Polycystic ovary syndrome (PCOS) is a heterogeneous condition characterized by androgen excess, ovulatory dysfunction, and polycystic ovaries. It is the most common endocrinopathy among women of reproductive age, affecting between 6.5% and 8% of women, and is the most common cause of infertility. Insulin resistance is almost always present in women with PCOS, regardless of weight, and they often develop diabetes and metabolic syndrome. The Rotterdam criteria are widely used for diagnosis. These criteria require that patients have at least two of the following conditions: hyperandrogenism, ovulatory dysfunction, and polycystic ovaries. The diagnosis of PCOS also requires exclusion of other potential etiologies of hyperandrogenism and ovulatory dysfunction. The approach to PCOS management differs according to the presenting symptoms and treatment goals, particularly the patient's desire for pregnancy. Weight loss through dietary modifications and exercise is recommended for patients with PCOS who are overweight. Oral contraceptives are the first-line treatment for regulating menstrual cycles and reducing manifestations of hyperandrogenism, such as acne and hirsutism. Clomiphene is the first-line drug for management of anovulatory infertility. Metformin is recommended for metabolic abnormalities such as prediabetes, and a statin should be prescribed for cardioprotection if the patient meets standard criteria for statin therapy.

To evaluate the prevalence of common mental disorders in women diagnosed with polycystic ovary syndrome as compared with paired controls without this syndrome. Cross-sectional study with a Control Group examining women between the ages of 18 and 30 who did not use antidepressants and who sought the Gynecology Service of the researched sites. For every woman diagnosed with the polycystic ovary syndrome, another with the same age, educational status and presence or absence of sexual partners was sought without this diagnosis. In total, 166 patients agreed to participate, consisting of 95 diagnosed with polycystic ovary syndrome and 71 in the Control Group. The diagnosis of polycystic ovary syndrome was made by the presence of two from three criteria: oligomenorrhea or amenorrhea, clinical or biochemical hyperandrogenism and polycystic ovaries on transvaginal ultrasound, following exclusion of patients with Cushing's syndrome, congenital adrenal hyperplasia, and androgen-secreting tumors. Weight and height were measured to calculate the body mass index. The Self-Reporting Questionnaire, which evaluated 20 items, was used as an indicator of common mental disorders. A χ² analysis stratified by the category of body mass index was used to compare the prevalence of common mental disorders, between the groups of women with and without the polycystic ovary syndrome. There were no significant differences in age, education, presence of sexual partners, ethnicity, socioeconomic status, use of psychiatric medication, and search for consultation in mental health between the studied groups. The prevalence of obese women with indications of common mental disorders was significantly higher in women with polycystic ovary syndrome than in the Control Group. In the group with healthy body mass index, the incidence of common mental disorders was statistically significant different between women with polycystic ovary syndrome and normal controls (p=0.008).

The evaluation the β-endorphin plasma levels in lean women with polycystic ovary syndrome as well as in women without this disorder. The associations between β-endorphins and other laboratory parameters were also investigated. 31 women lean, defined as women with normal range body mass index, 15 with polycystic ovary syndrome and 16 without this disorder were included to the study. In all the patients the level of β-endorphins was measured. Also the diagnostic laboratory profile including hormone assessment was made in all patients. There were significant differences in β-endorphin levels between the 2 groups. The β-endorphin level was higher in the polycystic ovary syndrome group compared to the healthy controls (15.5±4.37 pg/ml vs. 6.9±2.47 pg/ml, p<0.0001). The β-endorphin levels positively correlated with cortisol at 8 am (R=0.632, p=0.011) and negatively correlated with sex hormone binding globuline (R=0.518, p=0.0478) in polycystic ovary syndrome group. Increase in β-endorphin level of 1 pg/ml was associated with an increase of cortisol at 8 am level of 1.134 µg/dl and decrease of sex hormone binding globuline of 0.948 nmol/l in polycystic ovary syndrome group. Our study showed that the levels of β-endorphins were significantly higher in lean patients with polycystic ovary syndrome than in lean controls. Moreover, β-endorphins levels were found to be correlated with other hormonal parameters. In this respect, β-endorphins may play a role in polycystic ovary syndrome pathophysiology. © Georg Thieme Verlag KG Stuttgart · New York.

Ghrelin is an endogenous appetite stimulant that may have a role in ovarian function. Women with polycystic ovary syndrome have anovulation and frequently weight management issues; however the associations between ghrelin and hormonal markers in polycystic ovary syndrome have not been well studied. In order to characterize the association between total ghrelin levels and ovarian function and the possible modification of this relationship by obesity, we examined total ghrelin levels and anti-mullerian hormone, total testosterone, and insulin in obese and non-obese women with and without polycystic ovary syndrome. Total ghrelin levels were lower in obese women with polycystic ovary syndrome (n = 45) compared to obese controls (n = 33) (p = 0.005), but similar in non-obese women with polycystic ovary syndrome (n = 20) compared to non-obese controls (n = 21) (p = NS). In the obese polycystic ovary syndrome group, anti-mullerian hormone was associated with ghrelin levels independent of age, insulin, and total testosterone (p = 0.008). There was no association between total ghrelin and anti-mullerian hormone levels in non-obese women with polycystic ovary syndrome, non-obese controls, or obese controls (p = NS). Our results provide evidence for a potential relationship between ghrelin and ovarian function in obese women with polycystic ovary syndrome that was not observed in non-obese women with polycystic ovary syndrome or controls.

Polycystic ovary syndrome is a heterogeneous disorder and its presentation varies with race and ethnicity. Reproductive-age women with polycystic ovary syndrome are at increased risk of metabolic syndrome; however, it is not clear if prevalence of metabolic syndrome and clustering of its components differs based on race and ethnicity. Moreover, the majority of these women do not undergo routine screening for metabolic syndrome. We sought to compare the prevalence of metabolic syndrome and clustering of its components in women with polycystic ovary syndrome in the United States with women in India, Brazil, Finland, and Norway. This is a cross-sectional study performed in 1089 women with polycystic ovary syndrome from 1999 through 2016 in 5 outpatient clinics in the United States, India, Brazil, Finland, and Norway. Polycystic ovary syndrome was defined by the Rotterdam criteria. Main outcome measures were: metabolic syndrome prevalence, blood pressure, body mass index, fasting high-density lipoprotein cholesterol, fasting triglycerides, and fasting glucose. Data from all sites were reevaluated for appropriate application of diagnostic criteria for polycystic ovary syndrome, identification of polycystic ovary syndrome phenotype, and complete metabolic workup. The US White women with polycystic ovary syndrome were used as the referent group. Logistic regression models were used to evaluate associations between race and metabolic syndrome prevalence and its components and to adjust for potential confounders, including age and body mass index. The median age of the entire cohort was 28 years. Women from India had the highest mean Ferriman-Gallwey score for clinical hyperandrogenism (15.6 ± 6.5, P < .001). The age-adjusted odds ratio for metabolic syndrome was highest in US Black women at 4.52 (95% confidence interval, 2.46-8.35) compared with US White women. When adjusted for age and body mass index, the prevalence was similar in the 2 groups. Significantly more Black

Women with polycystic ovary syndrome have substantially higher rates of insulin resistance, impaired glucose tolerance, type 2 diabetes, dyslipidemia, and metabolic syndrome when compared with women without the disease. Given the high prevalence of these comorbidities, guidelines issued by the American College of Obstetricians and Gynecologists and the Endocrine Society recommend that all women with polycystic ovary syndrome undergo screening for impaired glucose tolerance and dyslipidemia with a 2 hour 75 g oral glucose tolerance test and fasting lipid profile upon diagnosis and also undergo repeat screening every 2-5 years and every 2 years, respectively. Although a hemoglobin A1C and/or fasting glucose are widely used screening tests for diabetes, both the American College of Obstetricians and Gynecologists and the Endocrine Society preferentially recommend the 2 hour oral glucose tolerance test in women with polycystic ovary syndrome as a superior indicator of impaired glucose tolerance/diabetes mellitus. However, we found that gynecologists underutilize current recommendations for metabolic screening in women with polycystic ovary syndrome. In an online survey study targeting American College of Obstetricians and Gynecologists fellows and junior fellows, 22.3% of respondents would not order any screening test at the initial visit for at least 50% of their patients with polycystic ovary syndrome. The most common tests used to screen for impaired glucose tolerance in women with polycystic ovary syndrome were hemoglobin A1C (51.0%) and fasting glucose (42.7%). Whereas 54.1% would order a fasting lipid profile in at least 50% of their polycystic ovary syndrome patients, only 7% of respondents order a 2 hour oral glucose tolerance test. We therefore call for increased efforts to encourage obstetrician-gynecologists to address metabolic abnormalities in their patients with polycystic ovary syndrome. Such efforts should include education of physicians early in their

To compare the efficacy of thiazolidinediones (TZDs) and metformin in polycystic ovary syndrome (PCOS) patients. This systematic review study was conducted at Shengjing Hospital of China Medical University, Shenyang, China between January and February 2012. We searched the following databases MEDLINE, EMBASE, the Cochrane Library, and Chinese National Knowledge Infrastructure until January 2012. Six randomized controlled trials records involving 267 patients were retrieved. The effect of TZDs on body mass index (BMI) was significantly lower than metformin (p=0.001; standardized mean difference [SMD] = 0.40, 95% confidence interval [CI]; 0.16-0.65). The effect of TZDs on the Homeostasis Model of Assessment-Insulin Resistance Index was not significantly different from metformin (p=0.955, SMD = 0.01, 95% CI: -0.38-0.40). The effect of TZDs on the androgen level was not significantly different from metformin (serum total testosterone: p=0.287, SMD = 0.20, 95% CI: -0.17-0.57). Compared to metformin, TZDs had the same effectiveness in treating insulin sensitivity and lowering androgen in PCOS patients, but the effect on weight loss was not as good as metformin.

Polycystic ovary syndrome (PCOS) and periodontal disease (inflammatory diseases of the tissues around teeth) are common disorders associated with diabetes and cardiometabolic risk. Comprehensively examining the periodontal status in PCOS, this study suggests that the susceptibility for periodontal disease may significantly increase in patients with PCOS compared with healthy young women, and that local/periodontal oxidant status appears to be affected in PCOS.

Polycystic ovary syndrome is a complex endocrine disorder affecting numerous women of reproductive age across the globe. Characterized mainly by irregular menses, hirsutism, skewed LH: FSH ratios and bulky polycystic ovaries, this multifactorial endocrinopathy results in unfavorable reproductive and metabolic sequelae, including anovulatory infertility, type 2 diabetes, metabolic syndrome and cardiovascular disease in later years. Increasing evidence has shown that the manifestation of polycystic ovary syndrome (PCOS) is attributable to a cumulative impact of altered genetic, epigenetic and protein profiles which bring about a systemic dysfunction. While genetic approaches help ascertain role of causal variants in its etiology, tissue-specific epigenetic patterns help in deciphering the auxiliary role of environmental, nutritional and behavioral factors. Proteomics is advantageous, linking both genotype and phenotype and contributing to biomarker discovery. Investigating molecular mechanism underlying PCOS is imperative in order to gain insight into the pathophysiology of PCOS and formulate novel diagnostic and treatment strategies. In this review we have summarized these three aspects, which have been successfully utilized to delineate the pathomechanisms of PCOS.

Background. We previously found that expression of SET gene was up-regulated in polycystic ovaries by using microarray. It suggested that SET may be an attractive candidate regulator involved in the pathophysiology of polycystic ovary syndrome (PCOS). In this study, expression and cellular localization of SET protein were investigated in human polycystic and normal ovaries. Method. Ovarian tissues, six normal ovaries and six polycystic ovaries, were collected during transsexual operation and surgical treatment with the signed consent form. The cellular localization of SET protein was observed by immunohistochemistry. The expression levels of SET protein were analyzed by Western Blot. Result. SET protein was expressed predominantly in the theca cells and oocytes of human ovarian follicles in both PCOS ovarian tissues and normal ovarian tissues. The level of SET protein expression in polycystic ovaries was triple higher than that in normal ovaries (P < 0.05). Conclusion. SET was overexpressed in polycystic ovaries more than that in normal ovaries. Combined with its localization in theca cells, SET may participate in regulating ovarian androgen biosynthesis and the pathophysiology of hyperandrogenism in PCOS. PMID:23861679

Polycystic ovary syndrome affects 6  percent of women. Symptoms include hirsutism, acne, and infertility. This research explores the impact of polycystic ovary syndrome on women's lives using photovoice. Nine participants photographed objects related to their quality of life and made diary entries explaining each photograph. Three themes emerged from thematic analysis of the diaries: control (of symptoms and polycystic ovary syndrome controlling their lives), perception (of self, others, and their situation), and support (from relationships, health care systems, and education). These findings illuminate positive aspects of living with polycystic ovary syndrome and the role pets and social networking sites play in providing support for women with polycystic ovary syndrome. © The Author(s) 2014.

Polycystic ovary syndrome is the most frequently seen endocrine disorder in women of reproductive age with a prevalence of about 10%. To investigate the efficiency of growth differentiation factor 9 and bone morphogenetic protein 15 during folliculogenesis in a dehydroepiandrosterone-induced mouse Polycystic ovary syndrome model. Animal experimentation. Mice were divided into 3 groups: control, vehicle and Polycystic ovary syndrome. Polycystic ovary syndrome model mice were developed by the injection of dehydroepiandrosterone dissolved in 0.1 mL of sesame oil. Ovarian tissues were examined for growth differentiation factor 9 and bone morphogenetic protein 15 using immunofluorescent labelling and electron microscopic examinations. The immunoreactivity of growth differentiation factor 9 and bone morphogenetic protein 15 proteins decreased (p<0.05) in the Polycystic ovary syndrome group (27.73±8.43 and 24.85±7.03, respectively) compared with the control group (33.72±11.22 and 31.12±11.05, respectively) and vehicle group (33.95±10.75 and 29.99±10.72, respectively). Apoptotic changes were observed in granulosa cells, lipid vacuoles increased in Theca cells and thickening and irregularities were noted in the basal lamina of granulosa cells. An increased electron density in the zona pellucida in some of the multilaminar primary and secondary follicles in the Polycystic ovary syndrome model was also observed at the ultrastructural level. These results suggest that the decrease in the growth differentiation factor 9 and bone morphogenetic protein 15 expression initiated at the primary follicle stage effect the follicle development and zona pellucida structure and may cause subfertility or infertility in Polycystic ovary syndrome.

To explore the impact of the diagnosis of polycystic ovary syndrome on health/ill health identity, how women experience this diagnosis and their health beliefs. Polycystic ovary syndrome is a common and heterogeneous condition, giving rise to a wide range of different health concerns. Previous research on polycystic ovary syndrome has been dominated by the medical perspective and less is known about the experiences and needs of women. A qualitative study of 32 premenopausal adult women with polycystic ovary syndrome (diagnosis confirmed by Rotterdam criteria), aged between 18 and 45 years, recruited from a primary and secondary care setting. Thematic analysis of transcripts from 11 focus groups conducted between 2013-2015. Women identified a range of concerns affecting personal and reproductive identity, health knowledge and beliefs: (1) delays and barriers to diagnosis; (2) general lack of empathy by the medical profession; (3) difficulty in accessing specialist referral; (4) lack of information from professionals; (5) inconsistent and sometimes unsatisfactory experiences with medications; (6) insufficient help and advice regarding in/fertility; (7) relative lack of awareness or concern about longer term risks such as diabetes; and (8) significant discrepancies between the beliefs of women with polycystic ovary syndrome and how they experienced the attitudes of healthcare professionals. There appears to be a divergence between women's experience and attitudes of healthcare professionals. The diagnosis, support and lived experience of women with polycystic ovary syndrome could be enhanced by better professional recognition of these concerns, improved knowledge and communication about polycystic ovary syndrome and better access to support and specialist advice. © 2017 John Wiley & Sons Ltd.

Although not often discussed, the ovaries of women with polycystic ovary syndrome (PCOS) show all the hallmarks of increased TGF-β activity, with increased amounts of fibrous tissue and collagen in the ovarian capsule or tunica albuginea and ovarian stroma. Recent studies suggest that PCOS could have fetal origins. Genetic studies of PCOS have also found linkage with a microsatellite located in intron 55 of the extracellular matrix protein fibrillin 3. Fibrillins regulate TGF-β bioactivity in tissues by binding latent TGF-β binding proteins. We therefore examined expression of fibrillins 1–3, latent TGF-β binding proteins 1–4, and TGF-β 1–3 in bovine and human fetal ovaries at different stages of gestation and in adult ovaries. We also immunolocalized fibrillins 1 and 3. The results indicate that TGF-β pathways operate during ovarian fetal development, but most important, we show fibrillin 3 is present in the stromal compartments of fetal ovaries and is highly expressed at a critical stage early in developing human and bovine fetal ovaries when stroma is expanding and follicles are forming. These changes in expression of fibrillin 3 in the fetal ovary could lead to a predisposition to develop PCOS in later life.—Hatzirodos, N., Bayne, R. A., Irving-Rodgers, H.

Women with polycystic ovary syndrome are more likely to suffer from obesity, insulin resistance, and chronic low-grade inflammation. In fact, the excessive activation of monocytes exacerbates oxidative stress and inflammation. However, high-density lipoprotein cholesterol neutralizes the pro-inflammatory and pro-oxidant effects of monocytes. The aim of this study is to investigate whether monocyte counts to high-density lipoprotein cholesterol ratio can predict the inflammatory condition in patients with polycystic ovary syndrome. In this cross-sectional study, a total of 124 women (61 of them with polycystic ovary syndrome and 63 age-matched healthy volunteers) were included in the study population. Obese polycystic ovary syndrome patients (n = 30) with a body mass index of ≥25 kg/m 2 and lean polycystic ovary syndrome patients (n = 31) with a body mass index of < 25 kg/m 2 were compared to age-and body mass index-matched healthy subjects (30 obese and 33 non-obese). The monocyte counts to high density lipoprotein cholesterol values in women with polycystic ovary syndrome were significantly higher than in control subjects (p = 0.0018). Moreover, a regression analysis revealed that body mass index, the homeostasis model assessment of insulin resistance and the high sensitivity C-reactive protein levels were confounding factors that affected the monocyte counts to high density lipoprotein cholesterol values. Additionally, a univariate and multivariate logistic regression analysis demonstrated that the increased monocyte counts to high density lipoprotein cholesterol values were more sensitive than the other known risk factors (such as increased body mass index, homeostasis model assessment of insulin resistance and high sensitive C-reactive protein levels) in the prediction of the inflammation in patients with polycystic ovary syndrome. The present study demonstrated that the monocyte count to high density lipoprotein cholesterol may be a novel and

The aim of this study was to investigate the risk factors of coronary heart disease, CRP and Lipoprotein-a in polycystic ovary syndrome patients. Prospectively collected data of polycystic ovary syndrome patients (n=62) and control group (n=40) were compared. PCOS patients had higher HOMA-IR, CRP, DHEAS, free testosterone, FAI, LH and prolactin levels when compared to the control group. Lipoprotein-a levels did not differ between the groups. The obese PCOS group had statistically significantly higher fasting blood glucose, total cholesterol, triglyceride, free testosterone, insulin, CRP and HOMA-IR and statistically significantly lower HDL and SHBG when compared to normal weight PCOS persons. Fasting blood glucose, total cholesterol, LDL, SHBG, CRP, Lipoprotein-a, FSH, LH, TSH, DHEAS and prolactin levels did not differ between the normal weight and obese control groups. CRP levels increase in polycystic ovary syndrome patients and can be used as a marker of coronary heart disease. Future studies can be directed at treatments to decrease CRP levels, including antiinflammatory treatments.

Polycystic ovary syndrome (PCOS) is a heterogeneous and complex endocrine disease which among the female population belongs to the most widespread endocrinopathies and it is the most frequent cause of hyperthyroidism, anticoagulation and infertility. Insulin resistance is one of the important diabetology factors impacting hyperglycaemia in a majority of women with PCOS (60-80 %). Clinical expressions of PCOS include reproduction disorders, metabolic characteristics and psychological implications. Reproduction disorders include hyperthyroidism, menstruation cycle disorders, infertility and pregnancy complications as well as early abortions, gestational diabetes and pregnancy induced hypertension. Long-term metabolic risks of PCOS include type 2 diabetes mellitus, dyslipidemia, arterial hypertension and endothelial dysfunction. The available data confirms higher incidence of cardiovascular diseases in women with PCOS. In particular among obese women PCOS is more frequently associated with non-alcoholic hepatic steatosis, sleep apnoea syndrome and endometrial cancer. The literature includes some controversial data about the relationship between PCOS and autoimmunity. Women with PCOS are more prone to suffer from insufficient confidence with higher incidence of anxiety, depression, bipolar disorder and eating disorders. autoimmunity - diabetes mellitus - pregnancy - insulin resistance - metabolic syndrome - menstrual disorders - polycystic ovary syndrome.

By virtue of insulin resistance being the common etiology for polycystic ovary syndrome (PCOS) and metabolic syndrome, the cardiometabolic risks of these two syndromes are shared. The usual concerns of a PCOS patient are cosmetic or reproductive. However, there are more serious concerns past the reproductive age. Early treatment of insulin resistance, hypertension and hyperlipidemia reduces the long-term risk. This review highlights the unhealthy association of metabolic syndrome with PCOS and emphasizes the importance of early diagnosis, patient education and long-term follow-up beyond the reproductive age into menopause to prevent the long-term serious co-morbidities.

Polycystic ovary syndrome (PCOS) is a heterogeneous disorder, where the main clinical features include menstrual irregularities, sub-fertility, hyperandrogenism, and hirsutism. The prevalence of PCOS depends on ethnicity, environmental and genetic factors, as well as the criteria used to define it. On the other hand, metabolic syndrome is a constellation of metabolic disorders which include mainly abdominal obesity, insulin resistance, impaired glucose metabolism, hypertension and dyslipidaemia. These associated disorders directly increase the risk of Type 2 diabetes mellitus (DMT2), coronary heart disease (CHD), cardiovascular diseases (CVD) and endometrial cancer. Many patients with PCOS have features of metabolic syndrome such as visceral obesity, hyperinsulinaemia and insulin resistance. These place patients with PCOS under high risk of developing cardiovascular disease (CVD), Type 2 diabetes (DMT2) and gynecological cancer, in particular, endometrial cancer. Metabolic syndrome is also increased in infertile women with PCOS. The aim of this review is to provide clear and up to date information about PCOS and its relationship with metabolic syndrome, and the possible interaction between different metabolic disorders.

Polycystic ovary syndrome is associated with obesity and insulin resistance in the non-pregnant state, but little is known about insulin sensitivity in the pregnant state. Our objective was to compare insulin resistance in pregnant women with and without polycystic ovary syndrome and explore the impact of polycystic ovary syndrome on body composition in offspring at birth and at three years of age. A prospective cohort study including 2548 live-born singleton mother-child pairs residing in Odense municipality, Denmark, during 2010-2013. Of the 2548 women, 241 (9.4%) had polycystic ovary syndrome. Homeostatic model assessment for insulin resistance assessments were comparable in women with and without polycystic ovary syndrome. However, the subgroup of overweight women with polycystic ovary syndrome had significantly higher levels of homeostatic model assessment for insulin resistance than overweight women without polycystic ovary syndrome (mean ± 2 SD): 4.4 (3.1) vs. 3.6 (3.4), p = 0.004. Maternal polycystic ovary syndrome did not affect offspring birthweight after accounting for age. However, polycystic ovary syndrome, adjusted for maternal body mass index, was associated with increased body mass index at three years of age (mean ± 2 SD): 16.0 (2.2) vs. 15.7 (2.1) kg/m 2 , p = 0.04. In our cohort, maternal polycystic ovary syndrome was not associated with insulin resistance after correcting for body mass index and was not an independent predictor of offspring birthweight. However, both polycystic ovary syndrome and high maternal body mass index may increase risk of childhood obesity at three years of age. © 2017 Nordic Federation of Societies of Obstetrics and Gynecology.

Hyperprolactinemia is the most common pituitary hormone hypersecretion syndrome in both men and women. Polycystic ovary syndrome (PCOS) is one of the most common endocrinopathies affecting 5%-10% of reproductive age women. Here, we present a patient with irregular menses, obesity, hirsutism and infertility, and hyperprolactinemia who was diagnosed as PCOS and prolactinoma and admitted to our clinic. Prolactinoma and PCOS association is a rare condition. This 33-year-old woman was admitted to the internal medicine outpatient clinic for irregular menses, obesity, hirsutism and infertility, and hyperprolactinemia. Her laboratory results were as follows: prolactin was 74 ng/mL (normal range:1.8-20.3 ng/mL). Pelvic ultrasonography was correlated with polycystic ovary syndrome. Pituitary MRI showed 6x8 mm microadenoma at left half. Bromocriptine was started with 1.25 mg/day and increased to 5 mg/day. After six months of bromocriptine treatment her prolactin level was normal and no adenoma was detected in pituitary MRI. PCOS and prolactinoma association should be taken into account in PCOS cases with mild hyperprolactinoma.

The development of polycystic ovary syndrome and its exact pathophysiological mechanism is still unclear, but environmental and genetic factors likely play a role. Exposition to teratogenic effects during the prenatal development can lead to chronic diseases in the postnatal period. This finding confirms the common familial aggregation as well. A literature search was conducted up to January 1, 2016 for articles dealing with the genetic or epigenetic factors of polycystic ovary syndrome. This review will discuss the current understanding of the genetic basis and clinical presentation of this disease. Orv. Hetil., 2016, 157(32), 1275-1281.

Polycystic Ovary Syndrome in Adolescence

Polycystic ovary syndrome (PCOS) is a syndrome of variable combinations of menstrual irregularity, hirsutism or acne, and obesity. It can be diagnosed in adolescence and has early childhood antecedents. PCOS is the single most common endocrine cause of anovulatory infertility and a major risk factor for the metabolic syndrome and, in turn, development of type 2 diabetes mellitus (T2DM) in women. Thus, it appears that PCOS increases a woman’s risk of developing cardiovascular disease. Therefore, identifying girls at risk for PCOS and implementing treatment early in the development of PCOS may be an effective means of preventing some of the long-term complications associated with this syndrome. This article reviews the definition, clinical features, diagnosis, and treatment of PCOS. PMID:16085166

Polycystic ovary syndrome (PCOS) is the most common endocrine disorder that affects women of reproductive age and is characterized by ovulatory dysfunction and/or androgen excess or polycystic ovaries. Women with PCOS present a number of systemic symptoms in addition to those related to the reproductive system. It has been associated with functional derangements in adipose tissue, metabolic syndrome, type 2 diabetes, and an increased risk of cardiovascular disease (CVD). A detailed literature search on Pubmed was done for articles about PCOS, adipokines, insulin resistance, and metabolic syndrome. Original articles, reviews, and meta-analysis were included. PCOS women are prone to visceral fat hypertrophy in the presence of androgen excess and the presence of these conditions is related to insulin resistance and worsens the PCO phenotype. Disturbed secretion of many adipocyte-derived substances (adipokines) is associated with chronic low-grade inflammation and contributes to insulin resistance. Abdominal obesity and insulin resistance stimulate ovarian and adrenal androgen production, and may further increase abdominal obesity and inflammation, thus creating a vicious cycle. The high prevalence of metabolic disorders mainly related to insulin resistance and CVD risk factors in women with PCOS highlight the need for early lifestyle changes for reducing metabolic risks in these patients.

To compare genome-wide DNA methylation profiles in ovary tissue from women with polycystic ovary syndrome (PCOS) and healthy controls. Case-control study matched for age and body mass index. University-affiliated hospital. Ten women with PCOS who underwent ovarian drilling to induce ovulation and 10 healthy women who were undergoing laparoscopic sterilization, hysterectomy for benign conditions, diagnostic laparoscopy for pelvic pain, or oophorectomy for nonovarian indications. None. Genome-wide DNA methylation patterns determined by immunoprecipitation and microarray (MeDIP-chip) analysis. The methylation levels were statistically significantly higher in CpG island shores (CGI shores), which lie outside of core promoter regions, and lower within gene bodies in women with PCOS relative to the controls. In addition, high CpG content promoters were the most frequently hypermethylated promoters in PCOS ovaries but were more often hypomethylated in controls. Second, 872 CGIs, specifically methylated in PCOS, represented 342 genes that could be associated with various molecular functions, including protein binding, hormone activity, and transcription regulator activity. Finally, methylation differences were validated in seven genes by methylation-specific polymerase chain reaction. These genes correlated to several functional families related to the pathogenesis of PCOS and may be potential biomarkers for this disease. Our results demonstrated that epigenetic modification differs between PCOS and normal ovaries, which may help to further understand the pathophysiology of this disease.

While female sexual dysfunction is a frequent occurrence, characteristics in infertile women are not well delineated. Furthermore, the impact of infertility etiology on the characteristics in women with differing androgen levels observed in women with polycystic ovary syndrome and unexplained infertility has not been assessed. The objective of the study was to determine the characteristics of sexual dysfunction in women with polycystic ovary syndrome and unexplained infertility. A secondary data analysis was performed on 2 of Eunice Kennedy Shriver National Institute of Child Health and Human Development Cooperative Reproductive Medicine Networks clinical trials: Pregnancy in Polycystic Ovary Syndrome Study II and Assessment of Multiple Intrauterine Gestations From Ovarian Stimulation. Both protocols assessed female sexual function using the Female Sexual Function Inventory and the Female Sexual Distress Scale. Women with polycystic ovary syndrome had higher weight and body mass index than women with unexplained infertility (each P < .001), greater phenotypic (Ferriman-Gallwey hirsutism score, sebum score, and acne score; each P < .001), and hormonal (testosterone, free testosterone, and dehydroepiandrosterone; each P < .001) evidence of androgen excess. Sexual function scores, as assessed by the Female Sexual Function Inventory, were nearly identical. The Female Sexual Distress Scale total score was higher in women with polycystic ovary syndrome. The mean Female Sexual Function Inventory total score increased slightly as the free androgen index increased, mainly as a result of the desire subscore. This association was more pronounced in the women with unexplained infertility. Reproductive-age women with infertility associated with polycystic ovary syndrome and unexplained infertility, despite phenotypic and biochemical differences in androgenic manifestations, do not manifest clinically significant differences in sexual function.

Polycystic ovary syndrome (PCOS) affects 5-20% of women of reproductive age worldwide. The condition is characterized by hyperandrogenism, ovulatory dysfunction and polycystic ovarian morphology (PCOM) - with excessive androgen production by the ovaries being a key feature of PCOS. Metabolic dysfunction characterized by insulin resistance and compensatory hyperinsulinaemia is evident in the vast majority of affected individuals. PCOS increases the risk for type 2 diabetes mellitus, gestational diabetes and other pregnancy-related complications, venous thromboembolism, cerebrovascular and cardiovascular events and endometrial cancer. PCOS is a diagnosis of exclusion, based primarily on the presence of hyperandrogenism, ovulatory dysfunction and PCOM. Treatment should be tailored to the complaints and needs of the patient and involves targeting metabolic abnormalities through lifestyle changes, medication and potentially surgery for the prevention and management of excess weight, androgen suppression and/or blockade, endometrial protection, reproductive therapy and the detection and treatment of psychological features. This Primer summarizes the current state of knowledge regarding the epidemiology, mechanisms and pathophysiology, diagnosis, screening and prevention, management and future investigational directions of the disorder.

Polycystic ovary syndrome (PCOS): metformin.

PubMed

Cahill, David J; O'Brien, Katherine

2015-03-27

Polycystic ovary syndrome (PCOS) is classically characterised by an accumulation of incompletely developed follicles in the ovaries due to anovulation. However, since the publication of the Rotterdam criteria, there is acceptance that menstrual cycle and endocrine dysfunction with hyperandrogenism is more important in reaching the diagnosis than ultrasound findings. It is diagnosed in up to 10% of women attending gynaecology clinics, but the prevalence in the population as a whole varies from 10% to 20%, depending on which diagnostic criteria are used. PCOS has been associated with hirsutism, infertility, acne, weight gain, type 2 diabetes, cardiovascular disease (CVD), and endometrial hyperplasia. We conducted a systematic review and aimed to answer the following clinical question: What are the effects of metformin on hirsutism and menstrual frequency in women with PCOS? We searched: Medline, Embase, The Cochrane Library, and other important databases up to May 2014 (Clinical Evidence reviews are updated periodically; please check our website for the most up-to-date version of this review). We included harms alerts from relevant organisations such as the US Food and Drug Administration (FDA) and the UK Medicines and Healthcare products Regulatory Agency (MHRA). We found 14 studies that met our inclusion criteria. We performed a GRADE evaluation of the quality of evidence for interventions. In this systematic review we present information relating to the effectiveness and safety of the following interventions: metformin compared with placebo/no treatment, metformin compared with weight loss intervention, or metformin compared with cyproterone acetate-ethinylestradiol.

The aim of this study was to compare the effects of Metformin and Acarbose accompanying Clomiphene on the successful ovulation induction in infertile women with polycystic ovary syndrome.This randomized double blind clinical trial study was performed on 60 women with polycystic ovary syndrome. Women were selected and randomly divided in two control and intervention groups. Intervention group received Acarbose 100 mg/day for 3 months. In the first, second, and third weeks, they received 1 tablet, 2 tablets, and 3 tablets per day respectively. In addition, they received 100 mg Clomiphene from third to seventh day of menstruation, during the 3 month treatment period. The control group received Metformin 500 mg/day for 3 months. In the first, second, and third weeks, they received 1 tablet, 2 tablets, and 3 tablets per day respectively. In addition, they received 100 mg Clomiphene from third to seventh day of menstruation, during the 3 month treatment period. All the subjects in both groups before and after the treatment were examined for hirsutism, acne, oral glucose tolerance test, serum triglycerides, cholesterol, LDL, HDL. Also, induction of ovulation was assessed by vaginal ultrasound. The Mean of BMI and fasting glucose tolerance test in Acarbose group was less than Metformin group (P = 0.05). The mean of triglycerides, LDL and HDL levels did not differ between the two groups after the intervention (P > 0.05). The mean of cholesterol levels were different in the two groups after the intervention (P = 0.04). Frequency of ovulation induction in those who received Acarbose (78.5%) was more than those who received Metformin (46.6) (P = 0.012). Comparing with Metformin, Acarbose accompanying Clomiphene was more effective in ovulation induction and decreasing body mass index in infertile women with polycystic ovary syndrome.

Polycystic ovary syndrome is a multi-factorial disease. Its etiopathogenesis has not been elucidated in detail. It is the most common endocrine disorder in women of child-bearing age. This disease entity is primarily characterized by disrupted ovulation and hyperandrogenism, but the clinical picture can be diversified and symptom intensity can vary. Currently, the sonographic assessment of ovaries is one of the obligatory criteria for the diagnosis of PCOS according to the Rotterdam consensus (2003) and Androgen Excess & PCOS Society (2006). This criterion is determined by the presence of ≥12 follicles within the ovary with a diameter of 2-9 mm and/or ovarian volume ≥10 cm(3). Such an ultrasound image in one gonad only is sufficient to define polycystic ovaries. The coexistence of polycystic ovaries with polycystic ovary syndrome is confirmed in over 90% of cases irrespective of ethnic factors or race. However, because of the commonness of ultrasound features of polycystic ovaries in healthy women, the inclusion of this sign to the diagnostic criteria of polycystic ovary syndrome is still questioned. The development of new technologies has an undoubted influence on the percentage of diagnosed polycystic ovaries. This process has caused an increase in the percentage of polycystic ovary diagnoses since the Rotterdam criteria were published. It is therefore needed to prepare new commonly accepted diagnostic norms concerning the number of ovarian follicles and the standardization of the technique in which they are counted. The assessment of anti-Müllerian hormone levels as an equivalent of ultrasound features of polycystic ovaries is a promising method. However, analytic methods have to be standardized in order to establish commonly accepted diagnostic norms.

To elucidate the prepubertal risk factors associated with the development of Polycystic Ovary Syndrome (PCOS) and determine the special clinical manifestations of the syndrome in this transitional time of a woman's life. To propose therapeutic targets and regimens, not only to prevent the long-term complications of the syndrome, but also to improve the self-esteem of a young girl who matures into womanhood. A systematic review of literature was performed through electronic database searches (Pubmed, Medline and Embase). Studies published in English-language, peer-reviewed journals from 1996 to 2013 were included. The selected studies focused on the risk factors, the unique features and treatment options of the PCOS in puberty. The pathogenesis of the PCOS was hypothesized to be based on interactions between genetic and certain environmental factors. The diagnosis was usually difficult in young girls. The syndrome was related to a greater risk of future infertility, type II diabetes mellitus, the metabolic syndrome and cardiovascular disease. Early treatment was crucial to prevent the long-term complications of the syndrome, especially infertility and cardiovascular disease. The recognition of the early signs of PCOS during or even before adolescence is of great importance. It is essential to establish the correct diagnosis for PCOS and rule out other causes of androgen excess in young women with hyperandrogenism. The type of treatment applied should be considered on an individual basis. PCOS = Polycystic Ovary Syndrome.

Polycystic ovary syndrome: current status and future perspective

Polycystic ovary syndrome (PCOS) is a widespread reproductive disorder that encompasses many associated health conditions and has an impact on various metabolic processes. PCOS is depicted by hyperandrogenism, polycystic ovaries, and anovulation. It increases the risk of insulin resistance (IR), type 2 diabetes, obesity, and cardiovascular disease. The etiology of the disease remains unclear, and the subjective phenotype makes a united diagnosis difficult among physicians. It seems to be a familial genetic syndrome caused by a combination of environmental and genetic factors. It can be linked with metabolic disorders in first-degree family members. PCOS is the cause of up to 30% of infertility in couples seeking treatment. Currently, there is no cure for PCOS. Despite the growing incidence of this syndrome, limited research has been done that encompasses the entirety of PCOS spectrum. In this review, the current status and possible future perspective will be discussed. PMID:24389146

Insulin Resistance, Metabolic Syndrome, and Polycystic Ovary Syndrome in Obese Youth.

2015-07-01

School nurses are well aware of the childhood obesity epidemic in the United States, as one in three youth are overweight or obese. Co-morbidities found in overweight or obese adults were not commonly found in youth three decades ago but are now increasingly "normal" as the obesity epidemic continues to evolve. This article is the second of six related articles discussing the co-morbidities of childhood obesity and discusses the complex association between obesity and insulin resistance, metabolic syndrome, and polycystic ovary syndrome. Insulin resistance increases up to 50% during puberty, which may help to explain why youth are more likely to develop co-morbidities as teens. Treatment of these disorders is focused on changing lifestyle habits, as a child cannot change his or her pubertal progression, ethnicity, or family history. School nurses and other personnel can assist youth with insulin resistance, metabolic syndrome, and polycystic ovary syndrome by supporting their efforts to make changes, reinforcing that insulin resistance is not necessarily type 2 diabetes even if the child is taking medication, and intervening with negative peer pressure. © 2015 The Author(s).

Objectives To identify differential protein expression pattern associated with polycystic ovary syndrome (PCOS). Methods Twenty women were recruited for the study, ten with PCOS as a test group and ten without PCOS as a control group. Differential in-gel electrophoresis (DIGE) analysis and mass spectroscopy were employed to identify proteins that were differentially expressed between the PCOS and normal ovaries. The differentially expressed proteins were further validated by western blot (WB) and immunohistochemistry (IHC). Results DIGE analysis revealed eighteen differentially expressed proteins in the PCOS ovaries of which thirteen were upregulated, and five downregulated. WB and IHC confirmed the differential expression of membrane-associated progesterone receptor component 1 (PGRMC1), retinol-binding protein 1 (RBP1), heat shock protein 90B1, calmodulin 1, annexin A6, and tropomyosin 2. Also, WB analysis revealed significantly (P<0.05) higher expression of PGRMC1 and RBP1 in PCOS ovaries as compared to the normal ovaries. The differential expression of the proteins was also validated by IHC. Conclusions The present study identified novel differentially expressed proteins in the ovarian tissues of women with PCOS that can serve as potential biomarkers for the diagnosis and development of novel therapeutics for the treatment of PCOS using molecular interventions.

History of discovery of polycystic ovary syndrome.

2017-01-01

Stein and Leventhal are regarded to have been the first investigators of polycystic ovary syndrome (PCOS); however, in 1721 Vallisneri, an Italian scientist, described a married, infertile woman with shiny ovaries with a white surface, and the size of pigeon eggs. It was not until the early 1990s at a National Institute of Health (NIH) sponsored conference on PCOS that formal diagnostic criteria were proposed and afterwards largely utilized. Many scientists tried to explain the pathophysiology of PCOS and many studies were made. It is now accepted that it is multifactorial, partly genetic; however, a number of candidate genes have been postulated. Insulin resistance has been noted consistently among many women with PCOS, especially in those with hyperandrogenism, but it is not included in any of the diagnostic criteria. Now there is strong evidence that cardiovascular disease risk factors and disturbances in carbohydrate metabolism are all increased in patients with PCOS compared to the healthy population. The criteria established by a group of experts during a conference in Rotterdam held in 2003 are obligatory (The Rotterdam ESHRE/ASRM - Sponsored PCOS Consensus Workshop Group). The subsequent "Rotterdam criteria" incorporated the size and morphology, as determined by an ultrasound, of the ovary into the diagnostic criteria.

Polycystic ovarian syndrome (PCOS) is characterized by a heterogeneous phenotype including chronic anovulation, hyperandrogenism and polycystic ovaries. The use of oral contraceptive pills (OCP) alters features characteristic for the syndrome. In the present study, PCOS features were compared between women using or not using OCP at the time of the study. One hundred and one women diagnosed with normogonadotrophic anovulatory infertility were included. A total of 81 (80%) women were diagnosed with PCOS (revised 2003 criteria). From these women, a total of 54 did not use OCP, whereas 27 women did. Corrected for age, women taking OCP had increased serum concentrations of sex hormone-binding globulin (P < 0.001). Serum concentrations of testosterone (P = 0.04) and androstenedione (P = 0.01) were decreased. These differences resulted in a decreased free androgen index for women currently taking OCP compared with women without (P < 0.001). The mean ovarian volume/ovary and the mean follicle number/ovary were not different. Use of OCP influences phenotype expression (the observable trait) of individual women known to suffer from PCOS by reducing hyperandrogenism. Despite taking OCP, women still fulfilled the revised 2003 criteria for the syndrome, as PCO morphology was still present. Hence, OCP use does not appreciably affect the PCOS phenotype.

Metabolic syndrome is an increasing pathology in adults and in children, due to a parallel rise of obesity. Sedentary lifestyle, food habits, cultural influences and also a genetic predisposition can cause dyslipidemia, hypertension, abdominal obesity and insulin resistance which are the two main features of metabolic syndrome. Polycystic ovary syndrome (PCOS) is a condition directly associated with obesity, insulin resistance (HOMA index) and metabolic syndrome, and it is very interesting for its relationship and overlap with the metabolic syndrome. The relationship between the two syndromes is mutual: PCOS women have a higher prevalence of metabolic syndrome and also women with metabolic syndrome commonly present the reproductive/endocrine trait of PCOS. Prevention and treatment of metabolic syndrome and PCOS are similar for various aspects. It is necessary to treat excess adiposity and insulin resistance, with the overall goals of preventing cardiovascular disease and type 2 diabetes and improving reproductive failure in young women with PCOS. First of all, lifestyle changes, then pharmacological therapy, bariatric surgery and laparoscopic ovarian surgery represent the pillars for PCOS treatment.

Basic infertility including polycystic ovary syndrome.

Infertility in women has many possible causes and must be approached systematically. The most common cause of medically treatable infertility is the polycystic ovary syndrome (PCOS). This syndrome is common in young women and is the cause of anovulatory infertility in 70% of cases. It is therefore an important condition to screen and manage in primary care medical settings. In the past 10 years, insulin sensitization with weight loss or metformin has been shown to be a safe and effective treatment for PCOS infertility that eliminates the risk of multiple pregnancy and may reduce the risk of early pregnancy loss as compared with ovulation-inductor drugs. The authors believe metformin should be considered as first-line therapy because it has the advantage to allow for normal single ovulation, for reduced early pregnancy loss, and, most importantly, lifestyle modifications and weight loss before pregnancy. Losing weight not only improves fertility but also reduces adverse pregnancy outcomes associated with obesity.

Polycystic ovary syndrome is the most common endocrine disease in women. Psychic consequences are significant; patients have difficulties to be pregnant and the disease disturbs the quality of life. Due to complications associated with polycystic ovary syndrome, studies on psychological state and disease perception of patients appear to be important. The aim of the authors was to assess how the disease influences quality of life and changes in body image. The authors used the Illness Intrusiveness Ratings Scale, Health-Related-Quality-of-Life Questionnaire for Women with Polycystic Ovary Syndrome and their own body image questionnaire. 121 women took part in the study. There was a negative correlation between illness intrusiveness and quality of life (r = -0.353) and a positive correlation between body image and quality of life (r = 0.614). A significant difference was observed in body satisfaction between patients who had visible body changes and those who had metabolic disturbances (p<0.05). Overweight patients who lost weight with lifestyle changes had significantly better quality of life (p<0.05). These results appear to be convincing in that in addition to gynecological care, psychotherapy could be offered to patients with polycystic ovary syndrome.

Polycystic ovary syndrome (PCOS) is a heterogeneous disorder characterized by chronic ovulatory dysfunction, hyperandrogenism, and polycystic ovaries. Wilms' tumor 1 (WT1) encoding a transcription factor involved in the differentiation of granulosa cells (GCs) regulates androgen receptor in the development of male genitalia. However, the expression pattern and possible role of WT1 in ovaries of PCOS patients are still unknown. GCs from 95 PCOS patients (PCOS group) and 62 healthy controls (control group) were isolated. The expression of WT1 in GCs was quantified using the reverse transcription-polymerase chain reaction. The correlation between WT1 expression and clinical characteristics was evaluated in PCOS patients. WT1 expression was increased in PCOS patients compared with the normal controls. The expression of WT1 was moderately correlated with testosterone (r = 0.334, p = 0.001) and luteinizing hormone (r = 0.357, p = 0.001) levels and the antral follicle counts (r = 0.337, p = 0.001). Our study provided novel insights into the relationship between hyperandrogenism and polycystic ovaries of PCOS and WT1. © 2018 S. Karger AG, Basel.

Polycystic ovary syndrome (PCOS) is a common endocrinopathy, associated with metabolic abnormalities. Metabolic features of various phenotypes of this syndrome are still debatable. The aim of present study hence was to evaluate the metabolic and hormonal features of PCOS phenotypes in comparison to a group of healthy control. A total of 646 reproductive-aged women were randomly selected using the stratified, multistage probability cluster sampling method. The subjects were divided into five phenotypes: A (oligo/anovulation + hyperandrogenism + polycystic ovaries), B (oligo/anovulation + hyperandrogenism), C (hyperandrogenism + polycystic ovaries) and D (oligo/anovulation + polycystic ovaries). Hormonal and metabolic profiles and the prevalence of metabolic syndrome among these groups were compared using ANCOVA adjusted for age and body mass index. Among women with PCOS (n = 85), those of groups A and C had higher serum levels of insulin and homeostatic model assessment for insulin resistance (HOMA-IR), compared to PCOS women of group D. Serum concentrations of cholesterol, low density lipoprotein, triglycerides and glucose in group A were higher than in other phenotypes, whereas the metabolic syndrome was more prevalent among group B. Women who had all three components of the syndrome showed the highest level of metabolic disturbances indicating that metabolic screening of the severest phenotype of PCOS may be necessary.

To investigate whether polycystic ovary syndrome further increases postpartum diabetes risk in women with gestational diabetes mellitus and to explore relationships between polycystic ovary syndrome and incident diabetes in women who do not develop gestational diabetes. This retrospective cohort study (Quebec Physician Services Claims; Hospitalization Discharge Databases; Birth and Death registries) included 34 686 women with gestational diabetes during pregnancy (live birth), matched 1:1 to women without gestational diabetes by age group, year of delivery and health region. Diagnostic codes were used to define polycystic ovary syndrome and incident diabetes. Cox regression models were used to examine associations between polycystic ovary syndrome and incident diabetes. Polycystic ovary syndrome was present in 1.5% of women with gestational diabetes and 1.2% of women without gestational diabetes. There were more younger mothers and mothers who were not of white European ancestry among those with polycystic ovary syndrome. Those with polycystic ovary syndrome more often had a comorbidity and a lower proportion had a previous pregnancy. Polycystic ovary syndrome was associated with incident diabetes (hazard ratio 1.52; 95% CI 1.27, 1.82) among women with gestational diabetes. No conclusive associations between polycystic ovary syndrome and diabetes were identified (hazard ratio 0.94; 95% CI 0.39, 2.27) in women without gestational diabetes. In women with gestational diabetes, polycystic ovary syndrome confers additional risk for incident diabetes postpartum. In women without gestational diabetes, an association between PCOS and incident diabetes was not observed. Given the already elevated risk of diabetes in women with a history of gestational diabetes, a history of both polycystic ovary syndrome and gestational diabetes signal a critical need for diabetes surveillance and prevention. © 2017 Diabetes UK.

Women with polycystic ovary syndrome have a three-fold higher risk of endometrial cancer. Insulin resistance and hyperlipidemia may be pertinent factors in the pathogenesis of both conditions. The aim of this study was to investigate endometrial sterol regulatory element binding protein-1 gene expression in polycystic ovary syndrome and endometrial cancer endometrium, and to correlate endometrial sterol regulatory element binding protein-1 gene expression with serum lipid profiles. A cross-sectional study was performed at Nottingham University Hospital, UK. A total of 102 women (polycystic ovary syndrome, endometrial cancer and controls; 34 participants in each group) were recruited. Clinical and biochemical assessments were performed before endometrial biopsies were obtained from all participants. Taqman real-time polymerase chain reaction for endometrial sterol regulatory element binding protein-1 gene and its systemic protein expression were analyzed. The body mass indices of women with polycystic ovary syndrome (29.28 ± 2.91 kg/m 2 ) and controls (28.58 ± 2.62 kg/m 2 ) were not significantly different. Women with endometrial cancer had a higher mean body mass index (32.22 ± 5.70 kg/m 2 ). Sterol regulatory element binding protein-1 gene expression was significantly increased in polycystic ovary syndrome and endometrial cancer endometrium compared with controls (p < 0.0001). Sterol regulatory element binding protein-1 gene expression was positively correlated with body mass index (r = 0.017, p = 0.921) and waist-hip ratio (r = 0.023, p = 0.544) in polycystic ovary syndrome, but this was not statistically significant. Similarly, statistically insignificant positive correlations were found between endometrial sterol regulatory element binding protein-1 gene expression and body mass index in endometrial cancer (r = 0.643, p = 0.06) and waist-hip ratio (r = 0.096, p = 0.073).

Activation of primordial follicles into the growing pool, selection of the dominant follicle, and its eventual ovulation require complex endocrine and metabolic interactions as well as intraovarian paracrine signals to coordinate granulosa cell proliferation, theca cell differentiation, and oocyte maturation. Early preantral follicle development relies mostly upon mesenchymal-epithelial cell interactions, intraovarian paracrine signals, and oocyte-secreted factors, whereas development of the antral follicle depends on circulating gonadotropins as well as locally derived regulators. In women with polycystic ovary syndrome (PCOS), ovarian hyperandrogenism, hyperinsulinemia from insulin resistance, and altered intrafollicular paracrine signaling perturb the activation, survival, growth, and selection of follicles, causing accumulation of small antral follicles within the periphery of the ovary, giving it a polycystic morphology. Altered adipocyte-ovarian interactions further compound these adverse events on follicle development and also can harm the oocyte, particularly in the presence of increased adiposity. Finally, endocrine antecedents of PCOS occur in female infants born to mothers with PCOS, which suggests that interactions between genes and the maternal-fetal hormonal environment may program ovarian function after birth.

Association of polycystic ovary syndrome with metabolic syndrome and gestational diabetes: Aggravated complication of pregnancy

PubMed Central

Yao, Kui; Bian, Ce; Zhao, Xia

2017-01-01

Polycystic ovary syndrome (PCOS) affects 5–20% of the reproductive age women globally. PCOS is diagnosed by the presence of hyperandrogenism, oligo-anovulation, and polycystic morphology of at least one ovary. Insulin resistance (IR), hyperinsulinemia and associated metabolic abnormalities including metabolic syndrome play a significant role in the development of PCOS. The chances of developing MS in PCOS women was shown to increase by almost 14-fold in patients with increasing body mass index. Even in the absence of overt obesity, a preferential deposition of intra-abdominal fat is noted in PCOS women and this intra-abdominal fat leads to impaired insulin action and functional IR and hyperandrogenism. Functional ovarian hyperandrogenism of ovaries was suggested to be a consequence of IR, which activates androgen synthesizing enzyme, cytochrome p450-c17α-hydroxylase, in ovarian theca cells and causes elevated oxidative stress accompanied by lower antioxidant status in ovaries, which contribute to PCOS pathogenesis. The elevated levels of luteinizing hormone that accompany the early stages of hyperandrogenemia, accelerate ovarian functional deterioration, which is further aggravated by hyperinsulinemia, in PCOS women. The risk of developing gestational diabetes in PCOS women is approximately three times greater, as compared to non-PCOS women, due to IR and hyperinsulinemia. Typical insulin-sensitizing drugs such as metformin, have been used to curtail IR and hyperinsulinemia in pregnant PCOS women, with varying results indicating the complexity of the disease and the need for better controlled studies and additional efforts for PCOS-specific drug discovery.

Adiponectin and Its Receptors in the Ovary: Further Evidence for a Link between Obesity and Hyperandrogenism in Polycystic Ovary Syndrome

PubMed Central

Comim, Fabio V.; Hardy, Kate; Franks, Stephen

2013-01-01

Polycystic ovary syndrome (PCOS), characterized by ovarian androgen excess, is the commonest endocrine disorder in women. Obesity increases androgen synthesis, a phenomenon attributed to the accompanying hyperinsulinemia. Our hypothesis was that adipokines, fat cell-derived hormones, play a direct role in modulating ovarian androgen secretion. Therefore, the aims of this study were to explore the effects of adipokines (in particular, adiponectin) on ovarian steroidogenesis and compare the expression of adiponectin receptors in ovaries from women with and without PCO. Sections of archived human ovaries (nine from women with normal ovaries and 16 with PCOS, classified histologically, with reference to menstrual history and ultrasound) were analysed by quantitative morphometry and the proportion of positive-labelling cells compared. In addition, studies of androgen production in relation to adipokine function in primary bovine theca cell culture were also performed. A significantly lower proportion of theca cells expressed adiponectin receptors 1 and 2 (AdipoR1, AdipoR2) in polycystic ovaries than in normal ovaries. In cultured theca cells, adiponectin suppressed androstenedione production and gene expression of LH receptor and key enzymes in the androgen synthesis pathway. Moreover, knockdown of genes for AdipoR1 and AdipoR2 was associated with increased androstenedione secretion by bovine theca cells. These results provide evidence for a direct link between fat cell metabolism and ovarian steroidogenesis, suggesting that disruption of adiponectin and/or its receptors plays a key role in pathogenesis of hyperandrogenism in PCOS.

For diagnosing of polycystic ovary syndrome (PCOS) it is currently recommended to follow the ESHRE criteria. For diagnosis according to them two of the following three symptoms are sufficient: 1. morphology of polycystic ovaria, 2. clinical manifestations of hyperandrogenism or laboratory proof of hyperandrogenemia, and 3. oligo-anovulation. PCOS is a complex disorder in whose pathogenesis genetic and environmental effects interact. It is not a gynecological disorder alone, the syndrome is accompanied by insulin resistance which leads to increased incidence of type 2 diabetes mellitus and impaired glucose tolerance (4 times and twice, independently of BMI). Also gestational DM occurs more frequently. Dyslipidemia, arterial hypertension, elevated CRP and homocysteine levels, endothelial dysfunction and greater intima-media thickness are also more frequent. It is not quite clear, however, whether women with PCOS suffer cardiovascular events more frequently as well. More often than is accidental PCOS is associated with depression, anxiety and eating disorders, further with nonalcoholic steatohepatitis and with the sleep apnoea syndrome - especially in obese women. Therapeutic measures include non-pharmacological methods - lifestyle adjustments focused on weight reduction in obese individuals, cosmetic measures for dermatologic manifestation of hyperandrogenism, in particular laser and pharmacotherapy (combined hormonal contraceptives and antiandrogens). Menstrual irregularities can be treated with contraceptives or cyclical administration of gestagens, also metformin can be used.

Oral contraceptives in polycystic ovary syndrome.

Polycystic ovary syndrome (PCOS) is the most common endocrine disorder of women of reproductive age and combined oral contraceptives (OCs) are often the first-line treatment of the syndrome by improving hyperandrogenism and regulating menstrual cycles. Oral contraceptives have some cardiovascular and metabolic effects that varies among different formulations depending upon the dose and type of the both estrogen and progestin components. These cardiometabolic effects of OCs raise some concerns about their long-term use in PCOS, but available data suggest that the benefits outweigh the risks. More studies are needed to clarify the safety of long-term use of OCs in PCOS.

Due to genetic heterogeneity and variable diagnostic criteria, genetic studies of polycystic ovary syndrome are particularly challenging. Furthermore, lack of sufficiently large cohorts limits the identification of susceptibility genes contributing to polycystic ovary syndrome. Here, we carried out a systematic search of studies deposited in the Gene Expression Omnibus database through August 31, 2016. The present analyses included studies with: 1) patients with polycystic ovary syndrome and normal controls, 2) gene expression profiling of messenger RNA, and 3) sufficient data for our analysis. Ultimately, a total of 9 studies with 13 datasets met the inclusion criteria and were performed for the subsequent integrated analyses. Through comprehensive analyses, there were 13 genetic factors overlapped in all datasets and identified as significant specific genes for polycystic ovary syndrome. After quality control assessment, there were six datasets remained. Further gene ontology enrichment and pathway analyses suggested that differentially expressed genes mainly enriched in oocyte pathways. These findings provide potential molecular markers for diagnosis and prognosis of polycystic ovary syndrome, and need in-depth studies on the exact function and mechanism in polycystic ovary syndrome.

MicroRNAs Related to Polycystic Ovary Syndrome (PCOS)

Polycystic ovary syndrome (PCOS) is the most common, though heterogeneous, endocrine aberration in women of reproductive age, with high prevalence and socioeconomic costs. The syndrome is characterized by polycystic ovaries, chronic anovulation and hyperandrogenism, as well as being associated with infertility, insulin resistance, chronic low-grade inflammation and an increased life time risk of type 2 diabetes. MicroRNAs (miRNAs) are small, non-coding RNAs that are able to regulate gene expression at the post-transcriptional level. Altered miRNA levels have been associated with diabetes, insulin resistance, inflammation and various cancers. Studies have shown that circulating miRNAs are present in whole blood, serum, plasma and the follicular fluid of PCOS patients and that they might serve as potential biomarkers and a new approach for the diagnosis of PCOS. In this review, recent work on miRNAs with respect to PCOS will be summarized. Our understanding of miRNAs, particularly in relation to PCOS, is currently at a very early stage, and additional studies will yield important insight into the molecular mechanisms behind this complex and heterogenic syndrome.

The purpose of this study was to compare the hormonal/clinical profiles and markers of bone health of women with hypothalamic amenorrhea (HA) to women with suspected HA and underlying polycystic ovary syndrome (PCOS). The results indicate that compared to women with HA, women with HA and underlying PCOS exhibit higher body mass index (BMI), bone mineral densities, and incidence of hyperandrogenism, that they may exhibit increased hyperandrogenism and irregular menses with weight gain, and that they remain at similar risk for osteopenia and osteoporosis.

Introduction Metabolic syndrome is comprised of a combination of the following states: increased insulin resistance, dyslipidemia, cardiovascular disease, and increased abdominal obesity. Women with polycystic ovary syndrome (PCOS) have an increased risk of developing metabolic syndrome over the course of their lives. Metabolic syndrome increases risk of major cardiovascular events, morbidity, quality of life, and overall health care costs. Though metabolic syndrome in women with PCOS is an area of great concern, there is no effective individual medical therapeutic to adequately treat this issue. Areas Covered This article will review key aspects of metabolic syndrome in PCOS. We will discuss classic and novel therapeutics to address metabolic syndrome in women with PCOS. We will conclude with the importance of developing strategic interventions to increase the compliance to lifestyle and dietary modification, in addition to appreciation of the emerging pharmaceutical therapeutics available. Expert Opinion Innovation in lifestyle modification, including diet, exercise, with and without dedicated stress reduction techniques is the future in treatment of metabolic syndrome in PCOS. Application of novel interventions, such as group medical care, may improve future adherence to lifestyle modification recommendations, in addition to or in combination with pharmaceutical therapeutics.

Whether electroacupuncture is effective for patients with polycystic ovary syndrome is still inconclusive. Therefore, this study aims to evaluate the add-on effects of electroacupuncture to conventional drugs for the treatment of polycystic ovary syndrome. This study is a two-center, open-labeled, randomized, controlled trial. A total of 116 eligible patients with polycystic ovary syndrome will be randomly allocated in a 1:1 ratio to the electroacupuncture plus clomiphene citrate group or to the clomiphene citrate group. Participants in the electroacupuncture plus clomiphene citrate group will receive electroacupuncture treatment in addition to clomiphene citrate capsules, whereas participants in the clomiphene citrate group will be prescribed clomiphene citrate capsules only. Electroacupuncture treatment will be performed from the fifth day of menstruation or withdrawal bleeding until the next menstruation, in three sessions per week for three menstrual cycles. The primary outcome is the ovulation rate. The secondary outcomes include the dominant follicle rate, mean number of dominant follicles, endometrial thickness, time point of ovulation, follicular size before ovulation, luteinizing hormone, estradiol level, and pregnancy rate. The measuring points for outcomes will be baseline and the completion of treatment. Any adverse events occurring during the trial process will be recorded. In addition, a quality-monitoring group independent from the research team will be set up to control the quality of the trial. The design and methodological rigor of this trial will allow for the collection of valuable data to evaluate the effectiveness of electroacupuncture for treating polycystic ovary syndrome. Therefore, this trial will contribute reliable evidence for use in clinical decision-making in acupuncture therapy of polycystic ovary syndrome as well as to future research in acupuncture for polycystic ovary syndrome.

Polycystic ovary syndrome (PCOS) is a disorder characterized by hyperandrogenism, ovulatory dysfunction, and polycystic ovaries. Its etiology remains unknown, and treatment is largely symptom based and empirical. PCOS has the potential to cause substantial metabolic sequelae, including an increased risk of diabetes and cardiovascular disease, and these factors should be considered when determining long-term treatment. The purpose of this document is to examine the best available evidence for the diagnosis and clinical management of PCOS.

Women with polycystic ovarian syndrome have a high prevalence of metabolic syndrome and type 2 diabetes mellitus. Blacks and Hispanics have a high morbidity and mortality due to cardiovascular disease and diabetes mellitus in the general population. Since metabolic syndrome is a risk factor for development of type 2 diabetes and cardiovascular disease, understanding any racial and ethnic differences in metabolic syndrome among women with polycystic ovarian syndrome is important for prevention strategies. However, data regarding racial/ethnic differences in metabolic phenotype among women with polycystic ovary syndrome are inconsistent. We sought to determine if there are racial/ethnic differences in insulin resistance, metabolic syndrome, and hyperandrogenemia in women with polycystic ovarian syndrome. We conducted secondary data analysis of a prospective multicenter, double-blind controlled clinical trial, the Pregnancy in Polycystic Ovary Syndrome II study, conducted in 11 academic health centers. Data on 702 women with polycystic ovarian syndrome aged 18-40 years who met modified Rotterdam criteria for the syndrome and wished to conceive were included in the study. Women were grouped into racial/ethnic categories: non-Hispanic whites, non-Hispanic blacks, and Hispanic. The main outcomes were the prevalence of insulin resistance, metabolic syndrome, and hyperandrogenemia in the different racial/ethnic groups. Body mass index (35.1 ± 9.8 vs 35.7 ± 7.9 vs 36.4 ± 7.9 kg/m 2 ) and waist circumference (106.5 ± 21.6 vs 104.9 ± 16.4 vs 108.7 ± 7.3 cm) did not differ significantly between non-Hispanic white, non-Hispanic black, and Hispanic women. Hispanic women with polycystic ovarian syndrome had a significantly higher prevalence of hirsutism (93.8% vs 86.8%), abnormal free androgen index (75.8% vs 56.5%), abnormal homeostasis model assessment (52.3% vs 38.4%), and hyperglycemia (14.8% vs 6.5%), as well as lower sex hormone binding globulin compared to non

To investigate factors associated with the response to ovarian stimulation in patients with polycystic ovary syndrome. Methods: The records of patients with polycystic ovary syndrome and infertility who underwent ovulation induction with clomiphene citrate were reviwed between January 2011 and December 2014 in Etlik Zübeyde Hanim Women's Health Training and Research Hospital Ankara, Turkey. The anthropometric and endocrine factors of patients who were resistant to treatment at a dose of 150 mg/day (n=84) were compared with those who responded with growth of at least one graaffian follicle at a dose of 50 mg/day (n=342). Results: Of the parameters examined, body mass index, luteinizing hormone level, and luteinizing hormone/follicle stimulating hormone ratio were significantly higher in the clomiphene citrate-resistant group compared with the responsive group. Conclusion: Reproductive treatment in patients with polycystic ovary syndrome show different outcomes. Significantly higher body mass index, luteinizing hormone level, and luteinizing hormone/follicle stimulating hormone ratio observed in clomiphene citrate resistant group can be a possible explanation for this impedance.

To characterize the population of patients excluded from a diagnosis of polycystic ovary syndrome (PCOS) when follicle number criteria are increased to 25 per ovary as suggested by the Androgen Excess and Polycystic Ovary Syndrome Society's recent task force. Cross-sectional study. Tertiary academic center. A total of 259 women with PCOS according to Rotterdam criteria who were systematically examined from 2007 to 2015, with 1,100 ovulatory women participating in the Ovarian Aging (OVA) Study as controls. Anthropometric measurements, serum testing, ultrasonic imaging, and comprehensive dermatologic exams. Body mass index (BMI), waist to hip ratio (WHR), serum cholesterol, fasting glucose and insulin, follicle count per ovary, biochemical hyperandrogenemia, and hirsutism. Forty-seven of 259 women meeting the Rotterdam criteria (18.1%) were excluded from a diagnosis of PCOS when the follicle number criteria was increased to 25. These women had clinical evidence of hyperandrogenism (68.1%) and biochemical hyperandrogenemia (44.7%), although fewer reported oligoanovulation (26.8%). The excluded women had elevated total cholesterol, fasting insulin, and homeostatic model of insulin resistance (HOMA-IR) when compared with controls despite controlling for age and BMI. The women excluded from the PCOS diagnosis by raising the threshold of follicle number per ovary to ≥25 continue to show evidence of metabolic risk.

Metformin is effective for the treatment of polycystic ovary syndrome, but conflicting results regarding its effect on adipocytokine levels (adiponectin, resistin, visfatin, and leptin) in patients with polycystic ovary syndrome receiving metformin treatment have been reported. To provide high-quality evidence about the effect of metformin treatment on adipocytokines in patients with polycystic ovary syndrome, relevant studies that assessed the levels of adipocytokines (adiponectin, resistin, visfatin, and leptin) in patients with polycystic ovary syndrome receiving treatment with metformin administration were reviewed and analyzed. A literature search was conducted in the SCI, PUBMED, EMBASE, and Elsevier databases, and personal contact was made with the authors. Standard mean differences and 95% confidence intervals were calculated and combined appropriately. To ensure synthesis of the best available evidence, sensitivity analyses were performed. A total of 34 data sets were included in 4 different outcomes, involving 744 women with polycystic ovary syndrome and adipocytokine levels measured both before and after metformin administration. Metformin treatment was associated with significantly elevated serum adiponectin concentrations (standard mean differences [95% confidence interval], -0.43 [-0.75 to -0.11]) and decreased serum leptin concentrations (0.65 [0.26 to 1.04]), whereas no significant difference in resistin level (-0.01 [-0.49 to 0.45]) or visfatin level (-0.04 [-1.55 to 1.46]) was found. Metformin administration was associated with increased serum adiponectin concentrations and decreased serum leptin levels. Further study is needed to elucidate whether this apparent effect decreases the incidence of type 2 diabetes and other metabolic diseases in patients with polycystic ovary syndrome later in life.

Clomiphene is the current first-line infertility treatment in women with the polycystic ovary syndrome, but aromatase inhibitors, including letrozole, might result in better pregnancy outcomes. In this double-blind, multicenter trial, we randomly assigned 750 women, in a 1:1 ratio, to receive letrozole or clomiphene for up to five treatment cycles, with visits to determine ovulation and pregnancy, followed by tracking of pregnancies. The polycystic ovary syndrome was defined according to modified Rotterdam criteria (anovulation with either hyperandrogenism or polycystic ovaries). Participants were 18 to 40 years of age, had at least one patent fallopian tube and a normal uterine cavity, and had a male partner with a sperm concentration of at least 14 million per milliliter; the women and their partners agreed to have regular intercourse with the intent of conception during the study. The primary outcome was live birth during the treatment period. Women who received letrozole had more cumulative live births than those who received clomiphene (103 of 374 [27.5%] vs. 72 of 376 [19.1%], P=0.007; rate ratio for live birth, 1.44; 95% confidence interval, 1.10 to 1.87) without significant differences in overall congenital anomalies, though there were four major congenital anomalies in the letrozole group versus one in the clomiphene group (P=0.65). The cumulative ovulation rate was higher with letrozole than with clomiphene (834 of 1352 treatment cycles [61.7%] vs. 688 of 1425 treatment cycles [48.3%], P<0.001). There were no significant between-group differences in pregnancy loss (49 of 154 pregnancies in the letrozole group [31.8%] and 30 of 103 pregnancies in the clomiphene group [29.1%]) or twin pregnancy (3.4% and 7.4%, respectively). Clomiphene was associated with a higher incidence of hot flushes, and letrozole was associated with higher incidences of fatigue and dizziness. Rates of other adverse events were similar in the two treatment groups. As compared with

Objective: Mean Platelet Volume (MPV) is an important indicator of platelet activation. It is known that MPV increases in patients with coronory artery disease, diabetes mellitus, atherosclerosis and Polycystic ovary syndrome (PCOS). Our aim was to measure the MPV in lean patients with polycystic ovary syndrome. Methods: The present study was designed to examine the platelet function by measuring MPV in non-obese women with PCOS. A total of 50 outpatients with PCOS were included. The control group consisted of 50 healthy subjects. Serum platelet, MPV, and white blood cell (WBC) levels were compared and evaluated retrospectively in all participants. These values were compared by statistical analysis. Results: There were no statistically significant difference in between groups regarding MPV (p═0.357), WBC (p═0,414) and platelet (p═0,666). Conclusion: There are studies implying MPV increase in PCOS patients, in our patients MPV levels did not correlate with PCOS except for patients with obesity. We think that PCOS itself has no effect on MPV levels and obesity changes MPV levels. PMID:24948985

Anti-Müllerian hormone and polycystic ovary syndrome.

PubMed

Bhide, Priya; Homburg, Roy

2016-11-01

Anti-Müllerian hormone (AMH) is expressed by the granulosa cells of the pre-antral and small antral follicles in the ovary. It is significantly higher in women with polycystic ovary syndrome (PCOS) due to an increased number of antral follicles and also a higher production per antral follicle. It is postulated to have an inhibitory role in folliculogenesis and may play an important role in the pathophysiology of anovulation associated with PCOS. Measurement of the serum AMH levels is very useful for the identification of PCOS and has been suggested as a diagnostic criterion. An international standardisation of the AMH assay, large population-based studies and a global consensus are needed before its incorporation into routine diagnosis. Serum AMH levels add significant value to the clinical markers for the prediction of hyperresponse to controlled ovarian stimulation for in vitro fertilisation treatment and development of ovarian hyperstimulation syndrome.

To characterize polycystic ovary syndrome (PCOS) in adolescents and determine whether a distinct clinical presentation differentiates normal-weight (NW) from overweight (OW) PCOS. Retrospective chart review of patients seen in a tertiary care center from 1998-2008 who met the National Institutes of Health and/or Rotterdam criteria for PCOS (N = 211; NW = 43, OW = 168). We collected data on clinical features, biochemical markers, and ultrasound findings. Patient age ranged from 11.3 to 20.3 years (mean, 15.7 ± 1.7 years), and body mass index (BMI) from 17.4 to 64.2 kg/m2 (mean, 31.7 ± 7.7 kg/m2). Seventy-one percent of patients were Caucasian, 85% had irregular menses, 69% reported hirsutism, 18% had moderate to severe acne, 91% had a high free androgen index (FAI), and 8% had abnormal thyroid-stimulating hormone (TSH) levels. The BMI-standard deviation (SD) score was 0.1 ± 0.5 in NW and 3.4 ± 1.8 in OW girls. NW girls were older at diagnosis (16.4 ± 1.4 years vs. 15.5 ± 1.7 years; P = .0006) than OW girls, less likely to have a family history of obesity (22% vs. 65%; P<.0001), and less likely to have acanthosis nigricans (11% vs. 68%; P<.0001). NW girls were more likely to have polycystic ovaries on ultrasound (88% vs. 52%; P = .01) and a lower FAI (7.3 ± 4.5 vs. 17.4 ± 12.9; P<.0001). The BMI-SD score was negatively associated with sex hormone binding globulin (r(s) = -0.52; P<.0001) and positively associated with FAI (r(s) = 0.42; P<.0001). NW girls are more likely to be older at diagnosis and have polycystic ovaries. Other differences in presentation between groups were attributable to differences in weight. NW PCOS is likely part of a continuous spectrum of clinical PCOS rather than a distinct entity.

To determine serum vascular endothelial growth factor B (VEGF-B) levels in polycystic ovary syndrome, their association with insulin resistance and β-cell dysfunction, and the effect of metformin on serum VEGF-B levels. A cross-sectional, interventional study. We recruited 103 women with polycystic ovary syndrome and 96 age-matched healthy controls. Serum VEGF-B levels were determined in all participants, and 44 polycystic ovary syndrome patients randomly received metformin. We measured VEGF-B levels in healthy controls and women with polycystic ovary syndrome before and after metformin treatment. Women with polycystic ovary syndrome had higher serum VEGF-B levels, which decreased with metformin treatment. In the lean and overweight/obese groups, patients with polycystic ovary syndrome had higher plasma VEGF-B levels than did healthy controls (P < 0·05). VEGF-B levels were correlated with body mass index, body fat percentage, M values, homeostasis model assessment of insulin resistance and β-cell function indices. A multiple linear regression analysis showed that VEGF-B level was associated with M values after adjusting for age, body mass index, serum sex hormones and serum lipids in women with polycystic ovary syndrome. Serum VEGF-B is significantly higher in women with polycystic ovary syndrome and is closely and positively related to insulin resistance. Metformin treatment reduces VEGF-B levels and ameliorates insulin resistance. © 2015 John Wiley & Sons Ltd.

Polycystic ovary syndrome (PCOS) is a common, complex endocrine disorder for women on reproductive age. A high incidence of ovulation failure is observed in PCO women and perhaps linked to insulin resistance related to metabolic features In the last few years some studies assessed hyperinsulinimea and insulin resistance attenuation effects, by insulin sensitizing agents such as metformin, in PCOS women suggesting potential scope for these drugs in CC ovulation induction quality improvement. Our prospective study aim is to compare the effectiveness of clomifene citrate plus metformin and clomifene citrate plus placebo in women with newly diagnosed polycystic ovary syndrome. From February 24 to September 29 (2007), PCOS was explored on women attending the Department of Obstetrics & Gynaecology sterility consultation unit (CHU Hedi Chaker-Sfax) according to the Rotterdam 2003 diagnostic criteria. PCOS patients were randomized to receive, in addition to clomifene citrate treatment, placebo or metformin 850 mg two times a day all ovulatory cycle for three trials maximum. Ovulation detection was done by the E2 serum measurements and ovarian transvaginal ultrasonography' evolution controlling on 7th, 11th and 13th day of the cycle. Within 7 months, 32 PCOS women were recruited in the study and equally allocated to the two groups. Baseline characteristics were similar in metformin group and placebo one. Ovulation was characterized by the presence of at least one mature follicle (> 16 mm), a circulating estradiol concentration in the edge of 150-250 pg and accessory an endometrial depth > 8 mm. The ovulation rate in the metformin group was 62.5% compared with 37.5% in the placebo group, a non-statistically significant (small study population) but important difference (1.66 times). Analyses show a higher mature follicle number and estradiol concentration in metformin group than in the placebo one. Metformin effect was, in our study, his only insulinosensitizer property

This retrospective cohort study evaluated the cumulative live birth rate in women with polycystic ovary syndrome (PCOS) and isolated polycystic ovaries (PCO) undergoing in-vitro fertilisation (IVF) treatment. We studied 104 women with PCOS, 184 with PCO and 576 age-matched controls undergoing the first IVF treatment cycle between 2002 and 2009. The main outcome measure was cumulative live birth in the fresh plus all the frozen embryo transfers combined after the same stimulation cycle. Women in both the PCOS (n = 104) and isolated PCO groups (n = 184) had higher ovarian response parameters compared to age-matched controls (n = 576), and higher rates of withholding fresh embryo transfer for risk of ovarian hyperstimulation syndrome (OHSS). The actual incidence of moderate to severe OHSS was significantly higher in the PCOS (11.5 %) but not the isolated PCO group (8.2%) compared to controls (4.9%). The live birth rates in the fresh cycle were comparable among the 3 groups, but the PCOS group had a significantly higher miscarriage rate compared to the other 2 groups. Cumulative live birth rate was significantly higher in the isolated PCO group (60.3%), but not the PCOS group (50.0%), compared to controls (47.5%). Women in the isolated PCO group, but not the PCOS group, had a significantly higher cumulative live birth rate compared to controls. This could be explained by the quantitative effect of the higher number of transferable embryos obtained per stimulation cycle, which is uncompromised by the unfavourable embryo competence otherwise observed in PCOS.

Polycystic ovary syndrome is a common cause of anovulation and infertility, and a risk factor for development of metabolic syndrome and endometrial cancer. Systematic review and meta-analysis of randomised controlled trials (RCT) that evaluated the effects of inositol as an ovulation induction agent. We searched MEDLINE, EMBASE, Cochrane and ISI conference proceedings, Register and Meta-register for RCT and WHO trials' search portal. We included studies that compared inositol with placebo or other ovulation induction agents. Quality of studies was assessed for risk of bias. Results were pooled using random effects meta-analysis and findings were reported as relative risk or standardised mean differences. We included ten randomised trials. A total of 362 women were on inositol (257 on myo-inositol; 105 on di-chiro-inositol), 179 were on placebo and 60 were on metformin. Inositol was associated with significantly improved ovulation rate (RR 2.3; 95% CI 1.1-4.7; I 2 = 75%) and increased frequency of menstrual cycles (RR 6.8; 95% CI 2.8-16.6; I 2 = 0%) compared with placebo. One study reported on clinical pregnancy rate with inositol compared with placebo (RR 3.3; 95% CI 0.4-27.1), and one study compared with metformin (RR 1.5; 95% CI 0.7-3.1). No studies evaluated live birth and miscarriage rates. Inositol appears to regulate menstrual cycles, improve ovulation and induce metabolic changes in polycystic ovary syndrome; however, evidence is lacking for pregnancy, miscarriage or live birth. A further, well-designed multicentre trial to address this issue to provide robust evidence of benefit is warranted.

2015-01-01

Background Metformin is effective for the treatment of polycystic ovary syndrome, but conflicting results regarding its effect on adipocytokine levels (adiponectin, resistin, visfatin, and leptin) in patients with polycystic ovary syndrome receiving metformin treatment have been reported. To provide high-quality evidence about the effect of metformin treatment on adipocytokines in patients with polycystic ovary syndrome, relevant studies that assessed the levels of adipocytokines (adiponectin, resistin, visfatin, and leptin) in patients with polycystic ovary syndrome receiving treatment with metformin administration were reviewed and analyzed. Methods A literature search was conducted in the SCI, PUBMED, EMBASE, and Elsevier databases, and personal contact was made with the authors. Standard mean differences and 95% confidence intervals were calculated and combined appropriately. To ensure synthesis of the best available evidence, sensitivity analyses were performed. Results A total of 34 data sets were included in 4 different outcomes, involving 744 women with polycystic ovary syndrome and adipocytokine levels measured both before and after metformin administration. Metformin treatment was associated with significantly elevated serum adiponectin concentrations (standard mean differences [95% confidence interval], −0.43 [−0.75 to −0.11]) and decreased serum leptin concentrations (0.65 [0.26 to 1.04]), whereas no significant difference in resistin level (−0.01 [−0.49 to 0.45]) or visfatin level (−0.04 [−1.55 to 1.46]) was found. Conclusions Metformin administration was associated with increased serum adiponectin concentrations and decreased serum leptin levels. Further study is needed to elucidate whether this apparent effect decreases the incidence of type 2 diabetes and other metabolic diseases in patients with polycystic ovary syndrome later in life.

We investigated the differences in anthropometrical, hormonal and insulin resistance parameters according to the subtype of polycystic ovary syndrome (PCOS) in Korean women. We recruited 166 women with PCOS and retrospectively recruited 277 controls. PCOS was diagnosed by irregular menstruation (IM), polycystic ovary (PCO) and hyperandrogenism (HA). Subjects were divided into four subgroups: the IM/HA/PCO group (n = 87, 52.4%), the IM/PCO group (n = 52, 31.3%), the IM/HA group (n = 23, 13.9%) and the HA/PCO group (n = 4, 2.4%). Clinical and biochemical variables were compared among the PCOS subgroups. The IM/HA/PCO and IM/HA groups showed higher body mass index (P < 0.001) and waist-to-hip ratio (P < 0.001) than the IM/PCO group. The IM/HA group had higher triglyceride levels than the other groups (P < 0.001). Higher fasting insulin (P < 0.001) and postprandial 2 h insulin (P < 0.01) were noted in the IM/HA/PCO group and the IM/HA group, compared with the IM/PCO group. Women with PCOS showed lower sex hormone-binding globulin (P < 0.001) and higher systolic blood pressure (BP) (P = 0.004), diastolic BP (P = 0.001), fasting insulin (P < 0.001), postprandial 2 h insulin (P < 0.001), homeostatic model for insulin resistance (P < 0.001) and clinical and biochemical parameters of metabolic syndrome (P < 0.05) compared with subjects without PCOS. Women with PCOS without HA are common in Korea and are less likely to have metabolic dysfunction, insulin resistance and elevated BP. PCOS without HA may be a mild phenotype of PCOS. Therefore, women with PCOS in Korea could have a reduced likelihood of having metabolic syndrome compared with women of other ethnicities.

To discuss the manifestations of endocrine and metabolism for polycystic ovary syndrome patients with different phenotype. This study selected 226 cases of Rotterdam Standard diagnosed polycystic ovary syndrome patients in People's Hospital of Zhengzhou from October 2013 to February 2015. The control group was the 100 cases of non hyperandrogen menstrual women as the control group. Polycystic ovary syndrome included 4 phenotype: /or anovulatio (O) combined with hyperandrogenism (H) and polycystic ovary morphology (P), phenotype of O and P, phenotype of H and P, and phenotype of O and P. All patients were detected for the clinical endocrine and metabolism related parameters. The phenotype of O and P occupied 55.8%, it had significant difference on the comparison between control group and the luteinizing hormone (LH) and luteinizing hormone/follicle stimulating hormone (LH/FSH) of phenotype of O, H and P, phenotype of O and H and phenotype of O and P; the testosterone (T) of phenotype of O,H and P and phenotype of O and H was apparently higher than phenotype of O and P and control group; The total cholesterol (TC) and triglyceride (TG) in phenotype of O, H and P was greatly higher than phenotype of O and P and control group. The phenotype of O and P was the most common phenotype in PCOS patients. It was same for the clinical endocrine and metabolism of two classic characteristics in PCOS. Compared to other PCOS phenotype, the metabolism in phenotype of O and P was lower. The phenotype classification of PCOS patients could better guide clinical individualized treatment in patients with PCOS.

The authors aimed to define the ocular symptomatology of women with polycystic ovaries and hyperandrogenism. Prospective, observational case series. Of the 62 consecutive patients with an ultrasonographic diagnosis of polycystic ovary (PCO), 16 were identified as having clinical and biochemical signs of hyperandrogenism. All women with a history of ocular symptoms (20/62 total patients [32.3%], 15/16 polycystic ovary syndrome (PCOS) patients [93.7%], and 5/46 PCO patients [10.8%]) underwent a complete eye examination with conjunctival impression cytologic sampling. Clinical measurements of tear function (tear film break-up time [BUT], Schirmer I test) were completed along with analysis of conjunctival goblet cell number, conjunctival immunostaining, and reverse-transcriptase polymerase chain reaction for the mucins MUC1 and MUC5AC. Clinical, histologic, and biochemical data of patients with PCOS were compared statistically with that of patients with PCO and with eight age- and gender-matched healthy controls. Eight of the most severely affected patients received systemic antiandrogen therapy and underwent further ocular evaluation four months after systemic therapy. Women with PCOS had greater conjunctival hyperemia (P < .001), dryness (P < .001), itching (P < .001), mucous discharge (P < .001), and contact lens intolerance (P < .001) than patients with PCO. Patients with PCOS had a significant reduction of the tear film BUT accompanied by a significant increase in goblet cell number and conjunctival MUC5AC messenger ribonucleic acid expression compared with both PCO patients and healthy subjects. Evaluation of the ocular surface should be considered in patients with PCO or PCOS. Women with PCOS were more likely to have itchy-dry eyes, decreased tear film BUT, and increased goblet cell density.

Polycystic ovary syndrome (PCOS) is a prevalent endocrinological disorder in reproductive-age women and is often associated with a metabolic syndrome. To investigate whether exercise intervention promotes PCOS prevention, a rat model was used. Polycystic ovary syndrome was induced by letrozole administration, and animals presented with obesity, sex hormone disorder, no ovulation, large cystic follicles, and increasing fasting insulin (FINS) and leptin levels. The intervention was set at 3 different intensities of swimming exercise: low (0.5 h/d), moderate (1 h/d), and high (2 h/d), and compared with a PCOS model group (letrozole administration without exercise intervention) and a control group. The exercise intervention in the low-intensity group did not produce changes in obesity, testosterone, progesterone (P), and follicle-stimulating hormone (FSH) levels. Moderate-intensity exercise reduced body weight, retained ovulation, and P levels were increased but remained lower than those in the control group. The FSH levels were significantly higher, and FINS and leptin levels were lower than in the model group ( P < 0.05) but not in the control group. The high-intensity group demonstrated the greatest effect of PCOS prevention. Testosterone, luteinizing hormone, FINS, and leptin levels were significantly lower in the high-intensity group, and FSH and P levels were higher compared with the model group. These results suggest that high-intensity exercise intervention can effectively prevent PCOS development.

Obesity Differentially Affects Phenotypes of Polycystic Ovary Syndrome

PubMed Central

Moran, Carlos; Arriaga, Monica; Rodriguez, Gustavo; Moran, Segundo

2012-01-01

Obesity or overweight affect most of patients with polycystic ovary syndrome (PCOS). Phenotypes are the clinical characteristics produced by the interaction of heredity and environment in a disease or syndrome. Phenotypes of PCOS have been described on the presence of clinical hyperandrogenism, oligoovulation and polycystic ovaries. The insulin resistance is present in the majority of patients with obesity and/or PCOS and it is more frequent and of greater magnitude in obese than in non obese PCOS patients. Levels of sexual hormone binding globulin are decreased, and levels of free androgens are increased in obese PCOS patients. Weight loss treatment is important for overweight or obese PCOS patients, but not necessary for normal weight PCOS patients, who only need to avoid increasing their body weight. Obesity decreases or delays several infertility treatments. The differences in the hormonal and metabolic profile, as well as the different focus and response to treatment between obese and non obese PCOS patients suggest that obesity has to be considered as a characteristic for classification of PCOS phenotypes.

Despite polycystic ovary syndrome (PCOS) being one of the most common endocrine disorders affecting reproductive-aged women, the etiopathogenesis and mechanisms of this syndrome remain unclear. Considering the ethical limitations in human studies, animal models that reflect many features of PCOS are crucial resources to investigate this syndrome. We aimed to introduce the most suitable rat model of PCOS that closely mimics the endocrine, ovarian and metabolic disturbances of human PCOS phenotype, while maintaining normal reproductive system morphology in adulthood, in order to further more detailed investigations about PCOS. We searched Pubmed, Science direct, and Web of science between 1990 and 2016, for relevant English manuscripts, using keywords including the "Polycystic Ovary Syndrome AND Rat Model" to generate a subset of citations relevant to our research. Included were those articles that compared at least both ovarian histology or estrous cycle and reproductive hormonal profiles in hormone-induced rat model of PCOS and controls. Differences in the findings between hormone-induced PCOS rats appear to be a result of the degree of transplacental transfer of the steroid administered into the fetus, dose and type of hormone, route of administration and timing and duration of exposure. We conclude that prenatal hormone-induced rat model with a lower dose and shorter time of exposure during the critical period of fetal development that exhibits endocrine, ovarian and metabolic disturbances similar to PCOS in women, while maintaining normal reproductive system morphology in adulthood is more suitable than postnatal hormone-induced rat model to facilitate studies regarding PCOS.

Androgen circle of polycystic ovary syndrome.

PubMed

Homburg, Roy

2009-07-01

Although the aetiology of polycystic ovary syndrome (PCOS) is still not known and the search for causative genes is proving elusive, it is generally agreed that hyperandrogenism is at the heart of the syndrome. Here, it is proposed that excess androgens are the root cause of PCOS starting from their influence on the female fetus in programming gene expression, producing the characteristic signs and symptoms which are then exacerbated by a propagation of excess ovarian androgen production from multiple small follicles, anovulation and insulin resistance in the reproductive life-span, thus setting up a vicious perpetual circle of androgen excess. This opinion paper, rather than being a full-scale review, is intentionally biased in support of this hypothesis that androgen excess is the 'root of all evil' in PCOS; in the hope that its acceptance could lead to more direct treatment of the syndrome in all its facets rather than the symptomatic treatment of side effects of androgen excess that we are addressing today.

Polycystic ovary syndrome (PCOS) is the most common female endocrine disorder with unknown etiology and with different complications. The aim of this study was to evaluate the effect of omega-3 supplementation on PCOS symptoms and metabolic syndrome. This double-blind clinical trial was performed in 2015 in Alzahra and Shahid Beheshti Hospitals, Isfahan, Iran, on 88 patients with PCOS. Intervention group took omega-3 supplements with dose of 2 g/day for 6 months (two capsules), but control group received two olive oil capsules. Finally, ultrasound and laboratory findings and the recovery rate of menstrual disorders in both groups were compared. After 6 months' intervention, waist circumference (WC) was significantly lower in omega-3 as compared to control (81.18 ± 2.87 vs. 84.22 ± 2.61 cm, respectively, P < 0.0001). High-density lipoprotein was increased (47.2 ± 1.37 vs. 41.56 ± 1.34 mg/dl, respectively, P < 0.0001) while low-density lipoprotein (107.79 ± 1.68 vs. 117.4 ± 1.57 mg/dl, respectively), triglyceride (116.02 ± 3.13 vs. 125.06 ± 2.91 mg/dl, respectively), and cholesterol (180.34 ± 6.34 vs. 189.56 ± 5.93 mg/dl, respectively) in omega-3 were significantly lower than control ( P < 0.0001).

Background Women with polycystic ovarian syndrome have a high prevalence of metabolic syndrome and type 2 diabetes mellitus. Blacks and Hispanics have a high morbidity and mortality due to cardiovascular disease and diabetes mellitus in the general population. Since metabolic syndrome is a risk factor for development of type 2 diabetes and cardiovascular disease, understanding any racial and ethnic differences in metabolic syndrome amongst women with polycystic ovarian syndrome is important for prevention strategies. However, data regarding racial/ethnic differences in metabolic phenotype amongst women with polycystic ovary syndrome is inconsistent. Objective To determine if there are racial/ethnic differences in insulin resistance, metabolic syndrome and hyperandrogenemia in women with polycystic ovarian syndrome. Study Design Secondary data analysis of a prospective multicenter, double blind controlled clinical trial, the Pregnancy in Polycystic Ovary Syndrome II study, conducted in 11 academic health centers. Data on 702 women with polycystic ovarian syndrome aged 18-40 years who met modified Rotterdam criteria for the syndrome and wished to conceive were included in the study. Women were grouped into racial/ethnic categories Non-Hispanic Whites, non-Hispanic Blacks and Hispanic. The main outcomes were the prevalence of insulin resistance, metabolic syndrome and hyperandrogenemia in the different racial/ethnic groups. Results BMI (35.1 ± 9.8 vs. 35.7 ± 7.9 vs. 36.4 ± 7.9 kg/m2) and waist circumference (106.5 ± 21.6 vs. 104.9 ± 16.4 vs. 108.7 ± 7.3 cm) did not differ significantly between non-Hispanic White, non-Hispanic Black and Hispanic women. Hispanic women with PCOS had a significantly higher prevalence of hirsutism (93.8 vs. 86.8%), abnormal free androgen index (FAI) (75.8 vs. 56.5%), abnormal homeostasis model assessment (HOMA) (52.3 vs. 38.4%) and hyperglycemia (14.8 vs. 6.5%), as well as lower sex hormone binding globulin compared to non

Polycystic ovary syndrome (PCOS) is the most common chronic endocrine disease in women. The prevailing complaints at a young age are menstrual irregularities, infertility, and hyperandrogenism-related problems. However, metabolic disorder-induced complications have been in the foreground over years. The review gives the current ideas on a change of clinical manifestations in the natural course of PCOS, as well as the pathogenetically grounded prevention of complications in patients.

Polycystic ovary syndrome (PCOS) is a heterogeneous disorder characterized by chronic anovulation, hyperandrogenism, polycystic ovary morphology (PCOM) and metabolic disturbances including insulin resistance and type 2 diabetes mellitus. Although insulin resistance could be associated with PCOM, recent studies have shown controversial results. The aim of this study was to determine the relationship between PCOM and insulin resistance. This was a cross-sectional clinical study. A total of 679 women with PCOS who were diagnosed using the National Institute of Child Health and Human Disease (NICHD) criteria and 272 control women were analysed. We measured fasting glucose and insulin levels, 75 g oral glucose tolerance test-derived glucose and insulin levels, testosterone levels, ovarian volume and follicle number. Polycystic ovary morphology was described in 543 women (80.0%) with PCOS. Women with PCOS had significantly higher 2 hours postload glucose, fasting and 2 hours postload insulin levels, ovarian volume, ovarian follicle numbers and lower insulin sensitivity compared with those of the controls (all P<.01). In women with PCOS, ovarian volume and ovarian follicle number were negatively associated with the quantitative insulin sensitivity check index after adjusting for age, body mass index and total testosterone; however, this association was not observed in the controls. In the logistic regression analysis, increased ovarian follicle number was associated with decreased insulin sensitivity in women with PCOS. In PCOS, enlarged ovarian volume and follicle excess were associated with insulin resistance, and the number of ovarian follicles could be a predictor of insulin resistance. © 2017 John Wiley & Sons Ltd.

We examined whether women with polycystic ovary syndrome (PCOS) have poorer health-related quality of life (HRQoL) than women in the general population and than patients with other medical conditions. Women with PCOS were recruited from an outpatient clinic and a control group was recruited from a family planning clinic. Both groups completed the Short Form-36 (SF-36) and the Polycystic Ovary Syndrome Questionnaire (PCOSQ). SF-36 data from the Oxford Health and Lifestyle Survey were used to compare PCOS with other conditions. Twenty-two women with PCOS and 96 control women took part. Women with PCOS scored lower in both summary scores of the SF-36 and in all domains of the PCOSQ. After adjusting for body mass index, the differences between the groups in the SF-36 disappeared, while those in the PCOSQ remained. When compared with asthma, epilepsy, diabetes, back pain, arthritis and coronary heart disease, our PCOS group had the same or better physical HRQoL but poorer psychological HRQoL. The PCOSQ showed good internal reliability, good concurrent validity and good discriminant validity. PCOS has a negative impact on HRQoL even when compared with other serious health conditions. The PCOSQ is reliable and valid for clinical use.

To investigate whether there is any therapeutic effect of colchicine on a rat model of polycystic ovary syndrome (PCOS). Twenty-two Wistar-Albino rats were randomly assigned into four with 8 rats in each group: control group; PCOS only group; PCOS-metformin group and PCOS-colchicine group. PCOS was induced by gavage with letrozole once daily at the concentration of 1 mg/kg orally with 21 consecutive days. After PCOS model assessment, PCOS-metformin group was received metformin orally with 500 mg/kg and PCOS-colchicine group was received colchicine orally with 1 mg/kg for the 35 day. Histopathology of ovaries, circulating estrone (E1), estradiol (E2), total testosterone, androstenedione and c-reactive protein (CRP) levels were evaluated. cystic and atretic follicle number was significantly decreased, but CRP and hormone parameters were not significantly changed with colchicine treatment. Colchicine has provided histopathological improvement compared with metformin in PCOS rat model.

Women with polycystic ovary syndrome (PCOS), the most common endocrine disorder among women of reproductive age, exhibit an adverse cardiovascular risk profile characteristic of the cardiometabolic syndrome. These women, compared with age- and body mass index-matched women without PCOS, appear to present a higher risk of insulin resistance, glucose intolerance, and dyslipidemia, and possibly a higher rate of type 2 diabetes mellitus and cardiovascular disease. However, despite the presence of cardiovascular risk factors and increased surrogate markers of cardiovascular disease, it is unclear whether they have accelerated atherosclerosis and greater mortality, the latter mainly because of a lack of endpoint studies. This article addresses, summarizes, and discusses salient data from the existing literature, including gaps and uncertainties, aspects, and mechanisms related to the spectrum of adverse cardiometabolic profile factors in women with PCOS.

Our aim is to assess whether the adiponectin (ADI) index (ADI/[FBG × FIns]) is a better surrogate index for the assessment of IR or metabolic syndrome (MetS).A population-based cross-sectional study was conducted including 100 healthy women and 99 polycystic ovary syndrome patients. The euglycemic-hyperinsulinemic clamp was performed. Circulating ADI levels were determined by ELISA.Polycystic ovary syndrome and polycystic ovary syndrome plus MetS subjects had higher products of fasting triglycerides and glucose (TyG), Homeostasis Model Assessment of Insulin Resistance (HOMA-IR), increased ratios of the area under the curve for insulin/the area under the curve for glucose (AUCi/AUCg), but lower ADI index as compared with healthy subjects. Partial correlation analysis in all populations showed that the M-value was significantly negatively correlated with HOMA-IR, TyG, TG/HDL, and AUCi/AUCg, and correlated positively with the ADI index. The r value of Pearson correlation between the ADI index and M-value was greater than that of the correlation between HOMA-IR, TyG, TG/HDL-C, and AUCi/AUCg. The optimal cut-off value of the ADI index for detection of IR was 0.67, with a sensitivity of 89.4% and a specificity of 88.1%, whereas for detection of MetS, it was 0.32, with a sensitivity of 88.7% and a specificity of 71.0%.The ADI index may be a surrogate marker in detecting IR and MetS.

Polycystic ovary syndrome in adolescent girls.

Polycystic ovary syndrome (PCOS) is a common heterogeneous disorder that appears to have its origins during the peripubertal years. The diagnostic conundrum is that the typical clinical features, irregular menses and acne, occur during normal female puberty. Understanding the physiologic origins and molecular basis of the dysregulated hypothalamic-pituitary-gonadal axis in PCOS is fundamental to interrupting the distinctive vicious cycle of hyperandrogenism and chronic anovulation. Newer ultrasound technology with better spatial resolution has generated controversy regarding the optimal imaging criteria to define polycystic ovary morphology. Using such equipment, the Androgen Excess PCOS Society Task Force Report recommends a threshold of at least 25 follicles per ovary as the definition of polycystic ovary morphology. The implementation and results of genome-wide association studies has opened a new window into the pathogenesis of PCOS. Recent genome-wide association studies have identified several loci near genes involved in gonadotropin secretion, ovarian function, and metabolism. Despite the impediments posed by phenotypic and genetic heterogeneity among women with PCOS, investigation into one locus, the DENND1A gene, is providing insight into the ovarian steroidogenesis. Anti-Mullerian hormone (AMH) has long been recognized to play a major role in the ovarian dysfunction. Recent animal data implicate AMH in the neuroendocrine dysregulation by demonstrating AMH-stimulated increased gonadotropin releasing hormone and luteinizing hormone secretion. PCOS is a common complex multifaceted disorder associated with genetic and environmental influences affecting steroidogenesis, steroid metabolism, neuroendocrine function, insulin sensitivity, pancreatic β cell function, and alternative adaptations to energy excess. Current research into the genetics and pathophysiology is reviewed. The difficulties inherent in diagnosing PCOS in adolescent girls are discussed.

Ovarian angiogenesis in polycystic ovary syndrome.

Polycystic ovary syndrome (PCOS) is the most prevalent endocrine pathology among women in reproductive age. Its main symptoms are oligo or amenorrhea, hyperandrogenism and the presence of ovarian cysts. It is also associated with infertility, obesity and insulin resistance. Mainly due to its heterogeneity, PCOS treatments are directed to manage its symptoms and to prevent associated diseases. The correct formation and regression of blood vessels during each ovarian cycle is indispensable for proper follicular development, ovulation and corpus luteum formation. The importance of these processes opened a new and promising field: ovarian angiogenesis. Vascular alterations characterize numerous pathologies, either with increased, decreased or abnormal angiogenesis. In the last years, several anomalies of ovarian angiogenesis have been described in women with PCOS. Therefore, it has been suggested that these alterations may be associated with the decreased - or lack of - ovulation rates and for the formation of cysts in the PCOS ovaries. Restoration of a proper vessel formation in the ovaries may lead to improved follicular development and ovulation in these patients. In the present review, we attempt to summarize the alterations in ovarian angiogenesis that have been described in women with PCOS. We also discuss the therapeutic approaches aimed to correct these alterations and their beneficial effects on the treatment of infertility in PCOS. © 2018 Society for Reproduction and Fertility.

Polycystic ovaries at ultrasound: normal variant or silent polycystic ovary syndrome?

It is not known whether polycystic ovaries (PCO) are an ovarian appearance without pathological meaning or whether they share with polycystic ovary syndrome (PCOS) the same ovarian follicle abnormality. There are few studies including strictly selected women with PCO but without other criteria of PCOS. In order to address these issues, we compared hormonal, metabolic and ultrasound parameters obtained from patients with PCO only, patients with PCOS and controls. This was a comparative analysis including three age-matched groups of 95 patients, who were included consecutively in a database: controls, patients with sonographic PCO but no symptoms (PCO group) and patients with PCOS. A clinical examination, fasting serum sampling and pelvic ultrasound examination were performed between cycle days 2 and 5 and results were compared between groups. The median serum anti-Mullerian hormone (AMH) level in the PCO group was intermediate between that in controls and that in the PCOS group (33.6 pmol/L, 19.8 pmol/L and 63.3 pmol/L, respectively), the differences being significant after adjustment for follicle number (P < 0.05), while the mean androgen serum level in the PCO group was similar to that in the control group and significantly lower than that in the PCOS group (P < 0.05) (median serum testosterone levels: 0.90 nmol/L, 0.79 nmol/L and 1.39 nmol/L; median androstenedione levels: 5.25 nmol/L, 4.37 nmol/L and 6.09 nmol/L, respectively). Body mass index, waist circumference and insulin levels had no effect on these differences. PCO is an abnormal condition, affected women showing no evidence of hyperandrogenism but having higher AMH serum levels compared with controls, suggesting a granulosa cell abnormality in PCO similar to that observed in PCOS. The absence of hyperandrogenism in PCO does not seem linked to the metabolic status. Copyright © 2012 ISUOG. Published by John Wiley & Sons, Ltd.

Treatment strategies for the infertile polycystic ovary syndrome patient.

Polycystic ovary syndrome (PCOS) is the most common endocrine disorder in women of reproductive age. Infertility is a prevalent presenting feature of PCOS, and approximately 75% of these women suffer infertility due to anovulation. Lifestyle modification is considered the first-line treatment and is associated with improved endocrine profile. Clomiphene citrate (CC) should be considered as the first line pharmacologic therapy for ovulation induction. In women who are CC resistant, second-line treatment should be considered, as adding metformin, laparoscopic ovarian drilling or treatment with gonadotropins. In CC treatment failure, Letrozole could be an alternative or treatment with gonadotropins. IVF is considered the third-line treatment; the 'short', antagonist-based protocol is the preferred option for PCOS patients, as it is associated with lower risk of developing ovarian hyperstimulation syndrome (specifically by using a gonadotropin--releasing hormone agonist as ovulation trigger), but with comparable outcomes as the long protocol.

Polycystic ovary syndrome is a complex and heterogeneous disease involving both reproductive and metabolic problems. It has been suggested a genetic predisposition in the etiology of this syndrome. The identification of calpain-10 gene (CAPN10) as the first candidate gene for type 2 diabetes mellitus, has focused the interest in investigating their possible relation with the polycystic ovary syndrome, because this syndrome is associated with hyperinsulinemia and insulin resistance, two metabolic abnormalities associated with type 2 diabetes mellitus. To investigate if there is association between the SNP-63 and the variant indel-19 of the CAPN10 gene and polycystic ovary syndrome in women of reproductive age. This study included 101 women (55 with polycystic ovary syndrome and 46 without polycystic ovary syndrome). The genetic variant indel-19 was identified by electrophoresis of the amplified fragments by PCR, and the SNP-63 by PCR-RFLP. The allele and genotype frequencies of the two variants do not differ significatly between women with polycystic ovary syndrome and control women group. The haplotype 21 (defined by the insertion allele of indel-19 variant and C allele of SNP-63) was found with higher frequency in both study groups, being more frequent in the polycystic ovary syndrome patients group, however, this difference was not statistically significant (p = 0.8353). The results suggest that SNP-63 and indel-19 variant of the CAPN10 gene do not represent a risk factor for polycystic ovary syndrome in our patients group. Copyright © 2015.

Polycystic ovary syndrome (PCOS) is the most common endocrine disorder in women of reproductive age and its etiology has not been characterized. Growth differentiation factor 8 (GDF8) is a member of the transforming growth factor-β superfamily that plays a critical role in the regulation of ovarian functions. However, the expression pattern of GDF8 in the human ovary is not yet clear. This study examined the cellular distribution of GDF8 and its putative cellular receptors (ACVR2A, ACVR2B, and ALK5) in a series of normal (n = 34) and PCOS ovaries (n = 14). The immunostaining of GDF8, ACVR2A, ACVR2B, and ALK5 was detected in the oocytes regardless of the developmental stage. All these proteins were localized in antral follicles in normal and PCOS ovaries, and the expression of these proteins increased with increasing follicle diameter. A significantly higher expression of GDF8 was detected in the granulosa cells than in the matched theca cells (TCs). These proteins were also localized in the luteal cells of the corpus luteum. Granulosa cells and TCs of large antral follicles in PCOS ovaries display a higher expression of these proteins. The higher expression levels of GDF8 and its functional receptors (ACVR2A, ACVR2B, and ALK5) in antral follicles of PCOS ovaries than those in normal ovaries suggest the possible involvement of dysregulated GDF8 in the pathogenesis of PCOS.

Polycystic ovary syndrome (PCOS) is a familial heterogeneous disorder affecting 6% to 10% of reproductive-age women. The use of criteria developed for adult women is problematic for the adolescent girl because the clinical features associated with PCOS are normal pubertal events. The recent consensus statement on PCOS in adolescents stated that hyperandrogenism and oligomenorrhea need to persist for at least 2 years to consider the diagnosis of PCOS. Although insulin resistance, hyperinsulinism, and obesity are often associated with PCOS, these features are not considered valid diagnostic criteria. Recent genomewide association studies implicate genetic loci involved in the hypothalamic-pituitary-ovarian axis. Copyright © 2016 Elsevier Inc. All rights reserved.

Polycystic ovary syndrome (PCOS) is a common endocrine disorder in women that has received an immense amount of attention in the recent years due to the possible associated risk of cardiovascular disease. Women with PCOS demonstrate an adverse cardiovascular profile characteristic of the cardiometabolic syndrome and an established risk of progression to type 2 diabetes. Despite the presence of cardiovascular risk factors and increased surrogate markers of cardiovascular disease, it is unclear if they develop accelerated atherosclerosis. This article summarized the recent development and findings of cardiovascular risk in women with PCOS, and finally the therapeutic options will be discussed.

Polycystic ovary syndrome (PCOS) is one of the most common endocrine disorders in humans, affecting approximately 7-8% of women of reproductive age. Despite the criteria adopted, PCOS is considered to be a predominantly hyperandrogenetic syndrome and the evaluation of metabolic parameters and insulin sensitivity is not mandatory. Most women with PCOS also exhibit features of the metabolic syndrome, including insulin resistance, obesity and dyslipidaemia. While the association with type 2 diabetes is well established, whether the incidence of cardiovascular disease is increased in women with PCOS remains unclear. Acknowledging the strong impact of insulin-resistance in the genesis of PCOS could be helpful not only to make the diagnosis more robust, but also for conferring better cardiovascular risk prevention. Several current studies support a strong recommendation that women with PCOS should undergo comprehensive evaluation for the metabolic syndrome and recognized cardiovascular risk factors, and receive appropriate treatment as needed. Lifestyle modifications remain the first-line therapy for all obese women with PCOS. However, many of these women do not lose weight easily. Insulin-sensitizing drugs are discussed as a promising and unique therapeutic option for the chronic treatment of PCOS.

Polycystic ovary syndrome (PCOS), which is characterized by anovulation, hyperandrogenism, and polycystic ovaries, is a complex endocrinopathy. Because the cause of PCOS at the molecular level is largely unknown, there is no cure or specific treatment for PCOS. Here, we show that transplantation of brown adipose tissue (BAT) reversed anovulation, hyperandrogenism, and polycystic ovaries in a dehydroepiandrosterone (DHEA)-induced PCOS rat. BAT transplantation into a PCOS rat significantly stabilized menstrual irregularity and improved systemic insulin sensitivity up to a normal level, which was not shown in a sham-operated or muscle-transplanted PCOS rat. Moreover, BAT transplantation, not sham operation or muscle transplantation, surprisingly improved fertility in PCOS rats. Interestingly, BAT transplantation activated endogenous BAT and thereby increased the circulating level of adiponectin, which plays a prominent role in whole-body energy metabolism and ovarian physiology. Consistent with BAT transplantation, administration of adiponectin protein dramatically rescued DHEA-induced PCOS phenotypes. These results highlight that endogenous BAT activity is closely related to the development of PCOS phenotypes and that BAT activation might be a promising therapeutic option for the treatment of PCOS.

The technological advance facilitates the hormonal analyses demonstrating the hyperandrogenism existence and the mechanism of the anovulation, the PCOS showed to be heterogeneous, reason why it was hindered to define it, this advanced the current trend to question the existence of the PCOS and to accept the convenience, either to change the name or to redefine it, leaving it as a simple syndrome with several phenotypes. The endocrine component includes abnormal secretion of insulin and consequently outlying resistance to this hormone, likewise is hyperandrogenism, dislipoproteinemia and obesity. The hormonal exams are unnecessary for the diagnostic and treatment; it is convenient to demonstrate for sonography the ovarian growth. Other dysfunctions like the congenital suprarenal hyperplasia, hyperprolactinemia and hypotiroidism should be discarded. The treatment should be individualized with relationship to the reason of the consultation and the patients age. It has not been demonstrated that the sensibilitizers use to the insulin avoids long term cardiovascular illness and diabetes. Therefore, the phenotype is heterogeneous with a fickle metabolic component and for it has arisen the restlessness of a better definition of the SPO.

Objective Many women with polycystic ovary syndrome (PCOS) experience infertility and hirsutism and often seek treatment for both concurrently. We investigated whether women who ovulate in response to treatment with clomiphene citrate), metformin, or both would have greater improvement in hirsutism compared to those who did not ovulate. Methods This is a secondary analysis evaluating the change in Ferriman-Gallwey score for the hirsute women (n = 505, 80.7%) from the Pregnancy in Polycystic Ovary Syndrome 1 study. This was a prospective, randomized, doubled-blind trial of 626 women with PCOS and infertility recruited from 12 university sites. They were treated with clomiphene citrate, metformin, or both (combination) for up to six cycles, and hirsutism evaluators were blinded to group assignment. Results There was a significant decrease in the Ferriman-Gallwey score between baseline and completion of the study in each of the three individual groups (clomiphene citrate, p=0.024; metformin, p=0.005; combination, p<0.001). There was no significant difference in the degree to which the hirsutism score changed when comparing the three groups (p=0.44). The change in hirsutism was not associated with the duration of treatment or with the presence or absence of ovulation. Conclusions In infertile hirsute women with PCOS, treatment with clomiphene citrate, metformin, or both for up to 6 cycles does not alter hirsutism.

To compare the efficacy of intrauterine insemination vs. timed intercourse with clomiphene citrate as a first-line treatment for anovulatory infertility associated with polycystic ovary syndrome. A randomized controlled trial following the CONSORT criteria. A university hospital and a private practice setting. 188 women (525 cycles) with polycystic ovary syndrome. Women received three consecutive cycles of ovulation induction with clomiphene citrate and intrauterine insemination (n=93, 259 cycles) or three consecutive cycles of clomiphene citrate with timed intercourse (n=95, 266 cycles). Clinical pregnancy rate per cycle, number of growing and mature follicles, serum estradiol, endometrial thickness at the hCG day, serum progesterone, ovulation, miscarriage and live birth rates. There were no differences between the two groups regarding the clinical pregnancy rate per cycle or per woman (8.49 vs. 7.89% and 23.6 vs. 22.1%; p=0.26 and p=0.33, respectively). Two twin pregnancies occurred in each group. Miscarriage and live birth rates were comparable (18.1 vs. 19% and 19.35 vs. 17.89%; p=0.31 and p=0.33, respectively). No ectopic, higher-order pregnancies or cases of ovarian hyperstimulation syndrome occurred. No differences were found regarding the number of follicles, serum progesterone, ovulation rates, estradiol levels or endometrial thickness at the hCG day (7.7±0.4 vs. 7.5±0.6mm; p=0.54). Ovulation induction with clomiphene citrate and timed intercourse is as effective as that with intrauterine insemination for achieving pregnancy in polycystic ovary syndrome and could represent the initial treatment option, being less invasive and less expensive than intrauterine insemination. © 2011 The Authors Acta Obstetricia et Gynecologica Scandinavica© 2011 Nordic Federation of Societies of Obstetrics and Gynecology.

To preliminary assess the efficacy of DONG 's extraordinary acupoints for the ovarian function of polycystic ovary syndrome. Fifty-six patients were randomized into an acupuncture group and a western medication group. In the acupuncture group, the acupoints were Fuke, Huanchao, Tianhuang (Yinlingquan, SP 9), Renhuang (Sanyinjiao, SP 6), Guanyuan (CV 4), Zigong (EX-CA 1). The treatment was used twice a week for continuous 12 weeks. In the western medication group, patients were given diane-35 for 3 menstrual cycles, once a day for 21 days with 7 days between the two sessions. The ratio of luteinizing hormone/flitropin (LH/FSH) was taken as the primary index, while the secondary indices were serum testosterone (T), FSH, LH, body mass index (BMI), the condition of ovary and menstruation. ①After treatment, the ratio of LH/FSH declined in both the two groups ( P <0.05, P <0.01). The decreasing values of the two groups were not significantly different ( P >0.05). ②T, LH and BMI dropped in the two groups ( P <0.05, P <0.01). The decreasing values of the three indices between the two groups were not significantly different (all P >0.05). ③The size of ovary did not change significantly after treatment in the two groups (both P >0.05), but the reduction degree of ovary size of the acupuncture group was larger than that of the western medication group ( P <0.05). The ovary number of more than 10 foliiculi in single ovary in the acupuncture group reduced compared with that before treatment ( P <0.05). The reduction degree of ovary number with the above feature was not significantly different between the two groups ( P >0.05). ④The times and days of menstruation within 3 months increased significantly in the two groups (all P <0.01), without significance of different valves between the two groups (both P >0.05). DONG 's extraordinary acupoints could improve the ovarian function of polycystic ovary syndrome, whose effect is similar as diane-35.

Polycystic ovary syndrome (PCOS) is characterized by chronic anovulation infertility, hyperandrogenemia, and frequently insulin resistance. This study investigated whether polymorphisms in the CAPN10 gene are related with PCOS etiology. The allelic frequencies and genotypes of CAPN10 polymorphisms UCSNP-44, 43, 19, and 63 were determined in 55 well characterized women with polycystic ovaries and 93 unrelated healthy controls using spectrofluorimetric analyses and real-time PCR. Our data indicate that CAPN10 UCSNP-44 allele is associated with PCOS in the Spanish population (P = 0.01). These results support a role of Calpain 10 gene in PCOS susceptibility in humans.

Several peripheral and central signals are involved in the sophisticated regulation of food intake. Women with polycystic ovary syndrome (PCOS) are prone to consume a diet higher in saturated fat and foods with high glycemic index and show impaired appetite regulation and measures of satiety. As a consequence, obesity, mostly of the central type, is prevalent in the syndrome and worsens the endocrine and metabolic profile of the affected patients. This review article briefly analyzes the current knowledge about the neuroendocrine mechanisms underlying the interplay between feeding behavior, obesity, and reproductive abnormalities in PCOS.

Polycystic ovary syndrome (PCOS) is a common endocrine-metabolic abnormality with a worldwide prevalence of 4% to 21%, depending on diagnostic criteria. The National Institutes of Health (NIH) is the largest single funding agency in the world; it invests nearly $30.0 billion annually in biomedical research. Using the NIH Research Portfolio Online Reporting tool, we searched for all grants awarded by the NIH for PCOS and three other disorders with similar degrees of morbidity and similar or lower mortality and prevalence [rheumatoid arthritis (RA), tuberculosis (TB), and systemic lupus erythematosus (SLE)]. We compared funding by the NIH for PCOS, RA, TB, and SLE research for the years 2006 to 2015, inclusive. PCOS, compared with RA, TB, and SLE, was relatively less funded (total mean 10-year funding was $215.12 million vs $454.39 million, $773.77 million, and $609.52 million, respectively). Funding for PCOS was largely provided by one NIH Institute/Center (ICs) vs at least two ICs for SLE and RA; more individual Research Project Grants were awarded for RA, SLE, and TB than for PCOS, whereas PCOS funding was more likely to be through General Clinical Research Centers Program or Specialized Centers Program awards. Our data suggest that PCOS research may be underfunded considering its prevalence, economic burden, metabolic morbidity, and negative impact on quality of life. Greater education of NIH leaders, including those at the National Heart, Lung, and Blood Institute and National Institutes of Diabetes and Digestive and Kidney Diseases; other federal and state agency leads; elected leaders; and the general public by professional societies, the scientific community, and patient advocates regarding this disorder is needed.

Polycystic ovary syndrome is an endocrine disorder affecting 1 in 10 women. Women with polycystic ovary syndrome can experience co-morbidities, including depressive symptoms. This research explores the experience of living with polycystic ovary syndrome and co-morbidities. Totally, 10 participants with polycystic ovary syndrome took part in Skype™ interviews and analysed using thematic analysis. Four themes emerged from the data: change (to life plans and changing nature of condition); support (healthcare professionals, education and relationships); co-morbidities (living with other conditions and depression, self-harm and suicidal ideation) and identity (feminine identity and us and them). The findings highlight the need for screening of women with polycystic ovary syndrome for depressive disorders. PMID:28070371

Polycystic ovary syndrome (PCOS) is one of the most common endocrine metabolic disorders of reproductive age women. The main signs of PCOS are as follows: androgen excess, menstrual dysfunction, infertility, obesity, and other numerous health problems. By different authors, the disorder affects 2-28% of reproductive age women. Polycystic ovary syndrome is characterized by presence of hyperandrogenism, anovulation, menstrual cycle disturbances, also by the other metabolic changes. The lack of well-defined and universally accepted diagnostic criteria makes identification of this syndrome confusing to many clinicians. There are only few studies concerning the correlations between phenotypic expression, body composition and PCOS, and relationship with the processes of growth and sexual maturation and various environmental factors (nutrition, physical activity, stress, and other factors). There is a lack of knowledge about further PCOS development and prognosis, considering the individual and environmental factors. Variation in human body composition and shape ranges considerably: many body size and shape indices (height, weight, body composition, and proportions) are the result of long evolution process and adaptation to environment. Obviously, the morphological body parameters, physiological and biochemical indices are complex and compound the interdependent system. By current literature, more than 50% of women are overweight or obese. If waist circumference and waist-to-hip ratio of women with PCOS increase, reproductive function and metabolic state of a woman is altered more than in cases when there are no changes in these parameters. The investigations of the strongest sexual dimorphism sign--the subcutaneous and visceral fat topography--showed that women with PCOS have greater adipose tissue mass in the areas of the abdomen, waist, and upper arms than control women. It is known that some indices of sexual dimorphism may be considered as the morphological signs of

Adiponectin and Polycystic Ovary Syndrome

Groth, Susan W.

2013-01-01

Introduction Polycystic ovary syndrome (PCOS) has a prevalence of 5–8% in women of reproductive age. Women with PCOS have an increased risk of metabolic syndrome and associated comorbidities. Adiponectin is a circulating protein produced by adipocytes. Circulating levels of adiponectin are inversely related to adipocyte mass. Low levels occur with insulin resistance, type 2 diabetes, metabolic syndrome, and obesity-related cardiovascular disease. This article reviews the literature on the link between adiponectin and PCOS and the potential use of adiponectin as a biomarker for PCOS. Method Data-based studies on adiponectin and PCOS and adiponectin measurement were identified through the Medline (1950–2009) and ISI Web of Knowledge (1973–2009) databases. Results Fifteen studies related to adiponectin and PCOS met inclusion criteria and were included in this review. These studies present evidence that adiponectin is linked to insulin resistance, insulin sensitivity, body mass index (BMI), and adiposity. In women with PCOS, lower levels, as opposed to higher levels, of adiponectin occur in the absence of adiposity. Conclusion The relationships between adiponectin and insulin resistance and sensitivity, metabolic syndrome, and BMI in women with PCOS suggest that adiponectin potentially could serve as a marker for disease risk and provide opportunity for earlier intervention if knowledge is successfully translated from laboratory to clinical practice. However, further study of the relationship between adiponectin and PCOS is required before there can be direct application to clinical practice. PMID:20498127

Cardiometabolic risk in polycystic ovary syndrome.

Polycystic ovary syndrome (PCOS) is a common disorder in women of reproductive age. Besides hyperandrogenism, oligomenorrhea and fertility issues, it is associated with a high prevalence of metabolic disorders and cardiovascular risk factors. Several genetic polymorphisms have been identified for possible associations with cardiometabolic derangements in PCOS. Different PCOS phenotypes differ significantly in their cardiometabolic risk which is worsening with severity of androgen excess. Due to methodological difficulties longer time-scale data about cardiovascular morbidity and mortality in PCOS and about possible beneficial effects of different treatment interventions is missing leaving many issues regarding cardiovascular risk unresolved.

Nonhuman primate models of polycystic ovary syndrome

With close genomic and phenotypic similarity to humans, nonhuman primate models provide comprehensive epigenetic mimics of polycystic ovary syndrome (PCOS), suggesting early life targeting for prevention. Fetal exposure to testosterone (T), of all nonhuman primate emulations, provides the closest PCOS-like phenotypes, with early-to-mid gestation T-exposed female rhesus monkeys exhibiting adult reproductive, endocrinological and metabolic dysfunctional traits that are co-pathologies of PCOS. Late gestational T exposure, while inducing adult ovarian hyperandrogenism and menstrual abnormalities, has less dysfunctional metabolic accompaniment. Fetal exposures to dihydrotestosterone (DHT) or diethylstilbestrol (DES) suggest androgenic and estrogenic aspects of fetal programming. Neonatal exposure to T produces no PCOS-like outcome, while continuous T treatment of juvenile females causes precocious weight gain and early menarche (high T), or high LH and weight gain (moderate T). Acute T exposure of adult females generates polyfollicular ovaries, while chronic T exposure induces subtle menstrual irregularities without metabolic dysfunction. PMID:23370180

The polycystic ovary syndrome (PCOS) it is a metabolic disorder with insulin resistance associated. Have been recently described contributor factors in the presence of insulin resistance that need to be studied. These factors can be the nutrients in the daily diet, final products of the advanced glycated end-products (AGEs), reactive derivatives of non enzymatic glucose-protein reactions either produced endogenously or ingested from dietary sources. The aim was to modifies the food intake to know the contribution on improve insulin resistance. Compare different diets and changes in insulin resistance in patients with polycystic ovary syndrome. As longitudinal, prospective and descriptive study, were included women with age among 18 to 40 years who received a compound with amino acids, extracts and anti-oxidants to dose of 660mg every 8 hours for 6 months. The inclusion approaches included the insulin resistance presence HOMA-IR > 2.6, elevated LH, and presence of ovaries with cysts by ultrasound. Statistical analysis with ANOVA one way to p <0.05. Were included a total of 30 patients, of which 28 patients had improvement in the insulin resistance from the 3 months, but until the 6 months they had significant difference (p<0.05), compared with 24 women from control group. With this result is demonstrated that it is necessary to modify the diet and to offer alimentary support to avoid the oxidative stress that takes impairment the insulin signaling with the subsequent insulin resistance.

To investigate the expression of silent information regulator 1 (SIRT1) in rats with polycystic ovary syndrome (PCOS) and its alteration after exenatide treatment. PCOS rat model was established by dehydroepiandrosterone induction. The animals were randomly divided into exenatide treatment group (EX group, n = 10), metformin treatment group (MF group, n = 10), PCOS group (PCOS group, n = 9) and normal control group (NC group, n = 10). Histological changes of the ovarian tissues were examined by HE staining. SIRT1 expression in the ovarian tissue was detected by RT-PCR and immunohistochemistry. Rats in the PCOS group lost their estrous cycle. Histological observation of the ovary showed saccular dilatation of the follicle, decreased number of corpora lutea, fewer layers of granulosa cells aligned loosely, and thickened layer of theca cells. The changes in reproductive hormones and the development of insulin resistance suggested the successful establishment of the animal models. Immunohistochemistry and Q-PCR detected the mRNA and protein expressions of SIRT1 in the ovary tissues of rats in the normal control group. The SIRT1 expression was significantly lower in PCOS group than in control group (P < 0.05); after drug intervention, the SIRT1 expression significantly increased in EX and MF groups (compared with the PCOS group), whereas no significant difference was noted between the EX group and MF group. The SIRT1 expression in the ovary tissue decreases in PCOS rats (compare with the normal rats) but can be up-regulated after Ex or MF treatment. These drugs may affect the process and development of PCOS by regulating the SIRT1 expression. Exenatide may be therapeutic for PCOS by up-regulating the SITR1 expression.

Polycystic ovary syndrome (PCOS) is the most common endocrine disorder amongst women of reproductive age and is associated with various metabolic perturbations, in addition to chronic anovulation and factors related to androgen excess. In general, women live longer than men and develop cardiovascular disease at an older age. However, women with PCOS, as compared with age- and body mass index-matched women without the syndrome, appear to have a higher risk of insulin resistance, hyperinsulinemia, glucose intolerance, dyslipidemia, and an increased prothrombotic state, possibly resulting in a higher rate of type 2 diabetes mellitus, fatty liver disease, subclinical atherosclerosis, vascular dysfunction, and finally cardiovascular disease and mortality. Further alterations in PCOS include an increased prevalence of sleep apnea, as well as various changes in the secretion and/or function of adipokines, adipose tissue-derived proinflammatory factors and gut hormones, all of them with direct or indirect influences on the complex signaling network that regulates metabolism, insulin sensitivity, and energy homeostasis. Reviews on the cardiometabolic aspects of PCOS are rare, and our knowledge from recent studies is expanding rapidly. Therefore, it is the aim of the present review to discuss and to summarize the current knowledge, focusing on the alterations of cardiometabolic factors in women with PCOS. Further insight into this network of factors may facilitate finding therapeutic targets that should ameliorate not only ovarian dysfunction but also the various cardiometabolic alterations related to the syndrome.

The aim of this study was to investigate the relationship between anger, impulsiveness, and biochemical parameters (testosterone, insulin, insulin resistance) in women with polycystic ovary syndrome. We recruited 84 women diagnosed with polycystic ovary syndrome according to the Rotterdam diagnostic criteria. Psychiatric interviews were performed using the Structured Clinical Interview for DSM-IV Axis I Disorders. The Barratt Impulsiveness Scale and the State Trait Anger Expression Inventory were also administered to each participant. Lastly, the women's biochemical parameters, which included total testosterone, free androgen index, dehydroepiandrosterone sulfate, insulin and insulin resistance, thyroid functions, and prolactin, were measured. A statistically significant correlation was found between participants' increasing total testosterone levels and total impulsiveness scores, and their increasing free androgen index levels and motor and non-planning-related impulsiveness (r=0.24, p=0.027; r=0.27, p=0.015; and r=0.26, p=0.017, respectively). High insulin and insulin resistance levels were associated with high non-planning-related impulsiveness scores (r=0.26, p=0.018; and r=0.26, p=0.019). Lastly, high trait anger and anger expression scores were related to high total testosterone and insulin and insulin resistance levels. Androgens and glucose dysregulation seemingly affect anger expression as well as the attentional, motor, and non-planning-related impulsiveness of women with polycystic ovary syndrome.

Idiopathic hirsutism (IH) or polycystic ovary syndrome (PCOS) are the most common causes of hirsutism which affects 5-10% of all women. The aim of this study was to evaluate the efficacy of flutamide plus diane 35 in the treatment of idiopathic hirsutism and polycystic ovary syndrome. 26 polycystic ovary syndrome and 24 idiopathic hirsutism patients were evaluated. Fifty patients were divided into two groups according to their diagnosis: idiopathic hirsutism or polycystic ovary syndrome. All patients received 125 mg Flutamide once a day and Diane 35 tablets for 21 days of each month, for 12 months. We measured hirsutism scores and hormonal levels of all patients. Evaluations were done before treatment, in the 6th and 12th months of therapy. There were no significant differences in Ferriman-Gallwey scores at the beginning and at the end of the therapy between the IH and PCOS groups. The decreases in Ferriman-Gallwey scores were significant in both groups in the 6th and 12th month of therapy. Combined treatment significantly decreased total and free testosterone, DHEAS and significantly increased SHBG levels in both groups and additionally decreased levels of LH, androstenodione and LH/FSH ratio in the polycystic ovary syndrome group. Combined treatment was effective and safe in the treatment of hirsutism. Combined regimens have additional effects on the treatment of hirsutism.

Polycystic ovary syndrome (PCOS) is the most common endocrine disorder in women. Its presentation is that of irregular menstruation associated with ovulation defects. Because of adverse outcomes such as metabolic and cardiovascular disorders, its diagnosis and treatment is very important. Therefore, the diagnostic value of prostatespecific antigen (PSA) in women with polycystic ovary syndrome was evaluated. A total of 32 women with PCOS and 32 aged matched healthy females were recruited in this case-control study. The subjects were compared by means of metabolic measures and serum PSA level. The correlations between these markers were evaluated. Sensitivity and specificity values and cut off levels of PSA were established for diagnosis of PCOS. Mean PSA, Ferriman Gallwey score (FGS), luteinizing hormone/follicle stimulating hormone ratio (LH/FSH), testosterone, dehydroepiandrosterone sulfate (DHEAS), 17(α) hydroxyprogesterone (17(α) HP) levels were significantly higher in PCOS (P<0.001, respectively). PSA levels greater than 0.07 ng/ml yielded a sensitivity of 91% and specificity of 82%, and was helpful as a diagnostic tool for women with PCOS. Circulating androgens and hirsutism were associated with higher levels of PSA in PCOS women. Our results showed direct correlation between PSA, hirsutism and hyperandrogemsm state. Therefore, it seems logical to use PSA level for detection of hyperandrogemsm state in women.

Sixty-three cases of polycystic ovary syndrome of kidney deficiency and phlegm stasis type were randomly divided in to a combined acupuncture and Chinese herb group (n=32) treated with acupuncture at Qihai (CV 6), Guanyuan (CV 4), et al. and oral administration of Chinese herbs, and a simple Chinese herb group (n=31) treated with oral administration of the same Chinese herbs as in the combined acupuncture and Chinese herb group. The therapeutic effects and changes of follicle stimulating hormone (FSH), luteotropic hormone (LH), testosterone (T) and LH/FSH were compared between the two groups. The total effective rate was 93.8% in the combined acupuncture and Chinese herb group and 80.6% in the simple Chinese herb group, the former being significantly better than the latter (P < 0.05). The decrease of T in the combined acupuncture and Chinese herb group was significantly su perior to that in the simple Chinese herb group (P < 0.01). Acupuncture combined with Chinese herb therapy is superior to the simple Chinese herb in the clinical therapeutic effect on polycystic ovary syndrome of kidney deficiency and phlegm stasis type and decrease of T level, indicating this method is a better one for polycystic ovary syndrome of kidney deficiency and phlegm stasis type.

To implement an evidence-based lifestyle modification intervention, guided by motivational interviewing, among a sample of infertile overweight and obese women with polycystic ovary syndrome to increase chances of conception while improving overall health. A prospective quantitative design was utilized (n = 12). Infertile overweight and obese women with polycystic ovary syndrome at an infertility practice completed questionnaires to assess diet and exercise practices at study onset and completion. Body mass index and weight measurements were obtained on participants at study onset and completion of intervention. Menstrual history was assessed by interview. There was a mean weight loss (p = .005) of 7(±5) pounds although a 5% weight reduction did not occur. Mean daily calorie (p = .005), fat (p = .006), and carbohydrate intake (p = .014) were significantly reduced. Frequency in brisk walking exercise significantly increased (p = .024). Frequency in home or gym exercise increased (p = .050). Menstrual cyclicity improved by 50% among prior amenorrheic subjects. An evidence-based lifestyle modification guideline could prove to be a cost effective intervention for infertile women with polycystic ovary syndrome (PCOS) who desire pregnancy. This intervention could be integrated into the primary care and reproductive medicine visits as sole therapy or in conjunction with infertility treatment. ©2013 The Author(s) ©2013 American Association of Nurse Practitioners.

The objective of this narrative review is to suggest a rational order of treatment choices in anovulatory women with polycystic ovary syndrome (PCOS), for whom a multitude of treatment options exist. In obese/overweight PCOS patients the importance of weight reduction should be stressed. Inositol, a dietary supplement with a documented effect on ovulation and without side effects in the doses recommended, may be suggested. Additional first line medical alternatives include insulin sensitizers, selective estrogen receptor modulators and aromatase inhibitors. Of these, the aromatase inhibitor letrozole and the combination of clomiphene citrate and metformin have the highest rates of ovulation and live birth. Second line treatments are ovarian electrocautery and low-dose follicle stimulating hormone stimulation. Controlled ovarian stimulation with in vitro fertilization, should be considered the last option since it carries a significant risk of ovarian hyperstimulation syndrome in patients with PCOS.

New adolescent polycystic ovary syndrome perspectives.

PubMed

Alemzadeh, R; Kansra, A R

2011-02-01

Polycystic ovary syndrome (PCOS) is a common but heterogeneous disorder that usually arises during puberty. This endocrine disorder is associated with chronic anovulation and hyperandrogenemia with clinical manifestation of oligomenorrhea, hirsutism and acne. While the underlying etiology of PCOS remains unknown, it is commonly associated with obesity and insulin resistance leading to increased risk of cardiovascular disease, dyslipidemia and type 2 diabetes mellitus in hyperandrogenemic phenotypes. Menstrual irregularities and insulin resistance in obese adolescents are usually indistinguishable from the clinical manifestations of PCOS and pose a diagnostic dilemma due to higher circulating androgens during puberty. Consequently, a universal consensus on the definition of hyperandrogenemia in adolescents has been elusive. Nevertheless, hyperandrogenemia, independent of obesity, in postmenarchal adolescents is associated with increased risk of cardiometabolic syndrome. Therefore, treatment strategies including lifestyle changes and/or use of insulin-sensitizers, hormone replacement and antiandrogens should be utilized in order to delay long-term cardiovascular and metabolic complications of this endocrinopathy.

To determine the prevalence of metabolic syndrome (MetSyn) and Framingham cardiovascular disease (CVD) risk in white and black adolescents and adult women with polycystic ovary syndrome (PCOS) compared with controls. Retrospective cohort study. Center for PCOS. Subjects with PCOS with data on race and cardiometabolic risk (n = 519). Controls were age and race matched from the National Health and Nutrition Examination Survey (NHANES) population (1999-2006). None. MetSyn, coronary heart disease risk, and general CVD risk. Black adolescents and young adults with PCOS had an increased prevalence of MetSyn compared with their white counterparts (adolescents relative risk 2.65 [95% confidence interval 1.29-5.4], adults relative risk 1.44 [95% confidence interval 1.21-2.6]). In contrast, there was no difference in risk of MetSyn between black and white adolescents and adult women in the NHANES dataset. After controlling for age and body mass index, black women with PCOS had a significantly increased prevalence of low high-density lipoprotein and high glucose. The general CVD risk was significantly increased in black adults with PCOS. This is the first study to comprehensively demonstrate increased risk of MetSyn in both black adolescents and adult women with PCOS compared with white subjects with PCOS. This racial disparity was not present in the NHANES controls. Longitudinal studies are needed to assess the independent impact of PCOS and race on CVD risk in women.

Polycystic Ovary Syndrome in the Pediatric Population

PubMed Central

2010-01-01

Abstract Polycystic ovary syndrome (PCOS) is a common disorder characterized by hyperandrogenism and disordered gonadotropin secretion, often associated with insulin resistance. The syndrome, which modulates both hormonal and metabolic processes, is the most common endocrinopathy in reproductive-age women and increases a woman's risk of infertility, endometrial pathology, and cardiometabolic disease. As it is currently defined, PCOS most likely encompasses several distinct diseases with similar clinical phenotypes but different underlying pathophysiological processes. However, hyperandrogenism remains the syndrome's clinical hallmark. The clinical manifestations of PCOS often emerge during childhood or in the peripubertal years, suggesting that the syndrome is influenced by fetal programming and/or early postnatal events. However, given that the full clinical spectrum of PCOS does not typically appear until puberty, a “two-hit” hypothesis has been proposed: (1) a girl develops hyperandrogenism via one or more of many different potential mechanisms; (2) the preexisting hyperandrogenism subsequently disturbs the hypothalamic–pituitary–ovarian axis, resulting in ovulatory dysfunction and sustained hyperandrogenism. No consensus guidelines exist regarding the diagnosis and management of PCOS in the pediatric population; however, because the syndrome is a diagnosis of exclusion, the clinical evaluation of girls suspected of having PCOS is aimed at excluding other causes of androgen excess and menstrual dysfunction. For the syndrome's management, emphasis is placed on lifestyle and symptom-directed treatment. PMID:20939704

To assess the interaction between insulin resistance and endothelial function and the optimal treatment strategy addressing cardiovascular risk in polycystic ovary syndrome. Randomized controlled trial. Controlled clinical study. Overweight age- and body mass index-matched women with polycystic ovary syndrome. Six months metformin (1 g two times per day, n = 36) or oral contraceptive pill (OCP) (35 microg ethinyl E(2)-2 mg cytoproterone acetate, n = 30). Fasting and oral glucose tolerance test glucose and insulin levels, endothelial function (flow-mediated dilation, asymmetric dimethylarginine, plasminogen activator inhibitor-1, von Willebrand factor), inflammatory markers (high-sensitivity C-reactive protein), lipids, and hyperandrogenism. The OCP increased levels of glucose and insulin on oral glucose tolerance test, high-sensitivity C-reactive protein, triglycerides, and sex-hormone binding globulin and decreased levels of low-density lipoprotein cholesterol and T. Metformin decreased levels of fasting insulin, oral glucose tolerance test insulin, high-density lipoprotein cholesterol, and high-sensitivity C-reactive protein. Flow-mediated dilation increased only with metformin (+2.2% +/- 4.8%), whereas asymmetric dimethylarginine decreased equivalently for OCP and metformin (-0.3 +/- 0.1 vs. -0.1 +/- 0.1 mmol/L). Greater decreases in plasminogen activator inhibitor-1 occurred for the OCP than for metformin (-1.8 +/- 1.6 vs. -0.7 +/- 1.7 U/mL). In polycystic ovary syndrome, metformin improves insulin resistance, inflammatory markers, and endothelial function. The OCP worsens insulin resistance and glucose homeostasis, inflammatory markers, and triglycerides and has neutral or positive endothelial effects. The effect of the OCP on cardiovascular risk in polycystic ovary syndrome is unclear. Copyright 2010 American Society for Reproductive Medicine. Published by Elsevier Inc. All rights reserved.

The Polycystic Ovary Morphology-Polycystic Ovary Syndrome Spectrum

Rosenfield, Robert L.

2014-01-01

Background Polycystic ovary syndrome (PCOS) is the most common cause of chronic hyperandrogenic anovulation. Two-thirds of PCOS patients have functionally typical PCOS, with typical functional ovarian hyperandrogenism manifest as 17-hydroxyprogesterone hyper-responsiveness to gonadotropin stimulation. Most, but not all, of the remainder have atypical functional ovarian hyperandrogenism. Many asymptomatic volunteers with polycystic ovary morphology (PCOM) have similar abnormalities. Objective The objective of this paper is to review the relationship of biochemical ovarian function to the clinical spectrum observed in PCOS and in normal volunteers with PCOM. Findings Adolescents and adults with PCOS are similar clinically and biochemically. Ninety-five percent of functionally typical PCOS have classic PCOS, ie, hyperandrogenic anovulation with PCOM. In addition to having more severe hyperandrogenism and a greater prevalence of PCOM than other PCOS, they have a significantly greater prevalence of glucose intolerance although insulin resistance is similarly reduced. Half of normal-variant PCOM have PCOS-related steroidogenic dysfunction, which suggests a PCOS carrier state. Conclusions There is a spectrum of ovarian androgenic dysfunction that ranges from subclinical hyperandrogenemia in some normal-variant PCOM to severe ovarian hyperandrogenism in most classic PCOS. A minority of mild PCOS cases do not fall on this spectrum of ovarian androgenic dysfunction, but rather seem to have obesity as the basis of their hyperandrogenism, or, less often, isolated adrenal androgenic dysfunction. Half of normal-variant PCOM also do not fall on the PCOS spectrum, and some of these seem to have excessive folliculogenesis as a variant that may confer mild prolongation of the reproductive lifespan. Improved understanding of PCOM in young women is needed. PMID:25840648

To evaluate the rate of major anomalies after first trimester (T1)-metformin exposure. Comparative, observational cohort study done at the Israeli Teratology Information Service between 2000 and 2013. 170 T1-metformin-exposed pregnancies [119 for diabetes and 51 for polycystic ovary syndrome (PCOS)] were prospectively followed-up and compared with 93 pregnancies of T1-insulin treated women and 530 non-teratogenic exposed (NTE) pregnancies. The differences in the rate of major anomalies excluding genetic/cytogenetic, and spontaneously resolved cardiovascular anomalies were not significant [4.4% (2/45) - metformin-PCOS, 1.1% (1/90) - metformin-diabetes, 2.5% (2/80) - insulin, and 1.7% (9/519) - NTE; OR adj metformin / NTE 1.77; 95% CI 0.45-7.01; OR adj insulin / NTE 1.69; 95% CI 0.35-8.11]. The rate of Cesarean section was higher in both the metformin-diabetes 51/90 (56.7%) and insulin 45/79 (57.0%) groups compared with the NTE group [138/503 (27.4%)]. Metformin-T1-exposure per se is not associated with an increased risk of major anomalies. Copyright © 2018 Elsevier Inc. All rights reserved.

Sheep models of polycystic ovary syndrome phenotype

Polycystic ovary syndrome (PCOS) is a fertility disorder affecting 5–7% of reproductive-aged women. Women with PCOS manifest both reproductive and metabolic defects. Several animal models have evolved, which implicate excess steroid exposure during fetal life in the development of the PCOS phenotype. This review addresses the fetal and adult reproductive and metabolic consequences of prenatal steroid excess in sheep and the translational relevance of these findings to PCOS. By comparing findings in various breeds of sheep, the review targets the role of genetic susceptibility to fetal insults. Disruptions induced by prenatal testosterone excess are evident at both the reproductive and metabolic level with each influencing the other thus creating a self-perpetuating vicious cycle. The review highlights the need for identifying a common mediator of the dysfunctions at the reproductive and metabolic levels and developing prevention and treatment interventions targeting all sites of disruption in unison for achieving optimal success.

Aim: To investigate the expression of silent information regulator 1 (SIRT1) in rats with polycystic ovary syndrome (PCOS) and its alteration after exenatide treatment. Methods: PCOS rat model was established by dehydroepiandrosterone induction. The animals were randomly divided into exenatide treatment group (EX group, n = 10), metformin treatment group (MF group, n = 10), PCOS group (PCOS group, n = 9) and normal control group (NC group, n = 10). Histological changes of the ovarian tissues were examined by HE staining. SIRT1 expression in the ovarian tissue was detected by RT-PCR and immunohistochemistry. Results: Rats in the PCOS group lost their estrous cycle. Histological observation of the ovary showed saccular dilatation of the follicle, decreased number of corpora lutea, fewer layers of granulosa cells aligned loosely, and thickened layer of theca cells. The changes in reproductive hormones and the development of insulin resistance suggested the successful establishment of the animal models. Immunohistochemistry and Q-PCR detected the mRNA and protein expressions of SIRT1 in the ovary tissues of rats in the normal control group. The SIRT1 expression was significantly lower in PCOS group than in control group (P < 0.05); after drug intervention, the SIRT1 expression significantly increased in EX and MF groups (compared with the PCOS group), whereas no significant difference was noted between the EX group and MF group. Conclusions: The SIRT1 expression in the ovary tissue decreases in PCOS rats (compare with the normal rats) but can be up-regulated after Ex or MF treatment. These drugs may affect the process and development of PCOS by regulating the SIRT1 expression. Exenatide may be therapeutic for PCOS by up-regulating the SITR1 expression. PMID:26339397

Polycystic ovary syndrome (PCOS) is a highly prevalent endocrine-metabolic disorder that implies various severe consequences to female health, including alarming rates of infertility. Although its exact etiology remains elusive, it is known to feature several hormonal disturbances, including hyperandrogenemia, insulin resistance (IR), and hyperinsulinemia. Insulin appears to disrupt all components of the hypothalamus-hypophysis-ovary axis, and ovarian tissue insulin resistance results in impaired metabolic signaling but intact mitogenic and steroidogenic activity, favoring hyperandrogenemia, which appears to be the main culprit of the clinical picture in PCOS. In turn, androgens may lead back to IR by increasing levels of free fatty acids and modifying muscle tissue composition and functionality, perpetuating this IR-hyperinsulinemia-hyperandrogenemia cycle. Nonobese women with PCOS showcase several differential features, with unique biochemical and hormonal profiles. Nevertheless, lean and obese patients have chronic inflammation mediating the long term cardiometabolic complications and comorbidities observed in women with PCOS, including dyslipidemia, metabolic syndrome, type 2 diabetes mellitus, and cardiovascular disease. Given these severe implications, it is important to thoroughly understand the pathophysiologic interconnections underlying PCOS, in order to provide superior therapeutic strategies and warrant improved quality of life to women with this syndrome.

This retrospective cohort study evaluated the obstetric outcomes in women with polycystic ovary syndrome (PCOS) and isolated polycystic ovaries (PCO) undergoing in vitro fertilization (IVF) treatment. We studied 104 women with PCOS, 184 with PCO and 576 age-matched controls undergoing the first IVF treatment cycle between 2002 and 2009. Obstetric outcomes and complications including gestational diabetes (GDM), gestational hypertension (GHT), gestational proteinuric hypertension (PET), intrauterine growth restriction (IUGR), gestation at delivery, baby's Apgar scores and admission to the neonatal intensive care unit (NICU) were reviewed. Among the 864 patients undergoing IVF treatment, there were 253 live births in total (25 live births in the PCOS group, 54 in the PCO group and 174 in the control group). The prevalence of obstetric complications (GDM, GHT, PET and IUGR) and the obstetric outcomes (gestation at delivery, birth weight, Apgar scores and NICU admissions) were comparable among the three groups. Adjustments for age and multiple pregnancies were made using multiple logistic regression and we found no statistically significant difference among the three groups. Patients with PCO ± PCOS do not have more adverse obstetric outcomes when compared with non-PCO patients undergoing IVF treatment.

To examine the relationship between polycystic ovary syndrome (PCOS), cardiovascular risk factors, cardiovascular disease (CVD), and chronic inflammation and analyze data regarding pharmacologic therapies that are recommended to reduce CVD risk in PCOS and the impact of those therapies on chronic inflammation. A search of MEDLINE (1950-October 2011) was conducted to identify clinical studies pertaining to the identification and treatment of CVD and chronic low-grade inflammation in PCOS. Search terms included polycystic ovary syndrome, cardiovascular disease, inflammation, metformin, thiazolidinedione, and statin. Bibliographies of these studies and review articles were also examined. English-language clinical studies evaluating the effect of metformin, thiazolidinediones, and statins on inflammatory markers, endothelial function, adhesion molecules, fibrinolysis, cytokines, and adipokines in PCOS were included. Women with PCOS have an increased prevalence of many cardiovascular risk factors including obesity, android fat distribution, insulin resistance, impaired glucose tolerance, diabetes, dyslipidemia, hypertension, and metabolic syndrome. Markers of chronic low-grade inflammation, which are associated with an increased risk of CVD, are also elevated in PCOS. Clinical guidelines recommend the use of insulin sensitizers and statins to prevent CVD in some patients with PCOS. Current literature indicates that each of these medication classes has beneficial effects on inflammation, as well. Although there are currently no studies to determine whether these treatments decrease CVD in PCOS, it can be hypothesized that drugs impacting chronic inflammation may reduce cardiovascular risk. Some studies show that metformin, thiazolidinediones, and statins have beneficial effects on inflammatory markers in PCOS; however, the data are inconsistent. There is insufficient information to recommend any pharmacologic therapies for their antiinflammatory effects in PCOS in the

To study oxidative stress (OS) markers on neonates. The specific aim was to evaluate advanced glycation end products (AGEs) and advanced oxidation protein products (AOPPs) serum levels along with the hormonal/metabolic profile and their possible relationship in a cohort of polycystic ovary syndrome PCOS(N) and gestational diabetes GDM(N) neonates and their mothers PCOS(M) and GDM(M). Prospective controlled study. Academic medical center. The study population comprised 151 mother/neonate pairs. Diet and/or insulin administration in GDM(M). Anthropometric, metabolic, hormonal parameters, and OS markers. The AGEs and AOPPs were higher in PCOS(M) and GDM(M) compared with controls (M). The same significant difference was observed in the corresponding groups of neonates. A strong relationship between mothers and neonates regarding AGEs (r = 0.605) and AOPPs levels (r = 0.735) was disclosed. Analogous findings were observed regarding androgens and insulin resistance in mothers and neonates, respectively. The present study demonstrated that in PCOS(N), the OS status was similar to that of GDM(N) and strongly associated with their mothers' oxidative status. These findings may have clinical implications, as exposure of PCOS(N) to high OS levels during pregnancy could affect several health issues of neonates.

To observe the therapeutic efficacy of Chinese medical syndrome typing and treatment combined cold needle puncture drainage operation or unipolar electrocoagulation drilling technique under laparoscope for treating clomiphene-resistant polycystic ovary syndrome (PCOS). Forty infertility patients with clomiphene-resistant PCOS were assigned to two groups using stratified random sampling method according to age, infertility time, and body mass index, 20 in each group. Patients in Group A were treated with Chinese medical syndrome typing and treatment combined cold needle puncture drainage operation, while those in Group B were treated with Chinese medical syndrome typing and treatment combined unipolar electrocoagulation drilling technique. After operation Chinese herbal treatment was administered to all patients according to syndrome typing. The serum levels of luteinizing hormone (LH), follicle stimulating hormone (FSH), androgen (T), estradiol (E2), and prolactin (PRL) were determined before and after operation. The ovulation was monitored. The pregnancy rate and the pregnancy outcomes were recorded after operation. There was no statistical difference in the 3-month spontaneous ovulation rate or the 1-year pregnancy rate (P > 0.05). The levels of LH, T, and PRL were significantly lower after operation than before operation in the two groups (P < 0.05). The menstruation and ovulation were obviously improved after operation. The total ovulation rate was 95% (19/20) in Group A. Successful pregnancy occurred in 15 cases of Group A. Ovarian hyperstimulation syndrome (OHSS) occurred in 1 case of Group A. The total ovulation rate was 90% (18/20) in Group B. Successful pregnancy occurred in 13 cases of Group B. Hypovaria occurred in 1 case of Group B.

A 13-year-old, obese girl presented with acute abdominal pain with abdominal distension for a year. The physical examination revealed marked abdominal distension with a large well-circumscribed mass sized 13×20 cm. Her body mass index (BMI) was 37.8 kg/m2. An abdominal CT scan revealed a huge multiloculated cystic mass and a left adnexal mass. She had an abnormal fasting plasma glucose and low HDL-C. Laparotomy, right salpingooophorectomy, left cystectomy, lymph node biopsies and partial omentectomy were performed. The left ovary demonstrated multiple cystic follicles over the cortex. The histologic diagnosis was a mucinous cystadenoma of the right ovary and a matured cystic teratoma of the left ovary. Both obesity and polycystic ovary syndrome (PCOS) are associated with a greater risk of ovarian tumours, where PCOS could be either the cause or as a consequence of an ovarian tumour. We report an obese, perimenarchal girl with bilateral ovarian tumours coexistent with a polycystic ovary and the metabolic syndrome.

To compare the effects of anastrozole (1 mg) and clomiphene citrate (CC; 100 mg) used for ovulation induction in women with polycystic ovary syndrome. Prospective controlled trial. University teaching hospital and private-practice setting. The study comprised a total of 216 infertile women (469 cycles) with polycystic ovary syndrome. Patients received anastrozole (1 mg/d; 115 patients, 243 cycles) for 5 days, starting on day 3 of menses. A matched historical group of patients with polycystic ovary syndrome who were treated with CC (100 mg/d; 101 patients, 226 cycles) was used as a control group. Timed intercourse was advised 24-36 hours after hCG injection. Number of follicles, serum E(2), serum P, endometrial thickness, and pregnancy and miscarriage rates. The mean age, parity, and duration of infertility in both groups were similar, but statistically significantly more polycystic ovaries were found in the anastrozole group (odds ratio = 2.44; 95% confidence interval = 1.19-5.02). The total numbers of follicles were significantly higher in the CC group (3.8 +/- 0.6 vs. 3.4 +/- 0.5). Endometrial thickness at the time of hCG administration was significantly greater in the anastrozole group (10.1 +/- 0.22 mm vs. 8.2 +/- 0.69 mm). The duration of stimulation was similar in the two groups. Ovulation occurred in 165 (67.9%) of 243 cycles in the anastrozole group and in 150 (68.6%) of 226 cycles in the CC group without significant difference. Serum P was significantly higher in the CC group (7.1 +/- 1.11 vs. 8.1 +/- 0.88 ng/mL). The pregnancy and miscarriage rates were similar in the two groups. Anastrozole was associated with significantly fewer mature and growing follicles, thicker endometrium, and slightly higher pregnancy rate. Anastrozole may be helpful in situations in which multiple pregnancy is not desirable or the risk of ovarian hyperstimulation syndrome is high.

It is unknown which phenotype of polycystic ovary syndrome (PCOS) has a greater metabolic risk and how to detect this risk. The aim of this study was therefore to compare the incidence of metabolic syndrome (MetS) and metabolic risk profile (MRP) for different phenotypes. A total of 100 consecutive newly diagnosed PCOS women in a tertiary referral hospital were recruited. Patients were classified into four phenotypes according to the Rotterdam criteria, on the presence of at least two of the three criteria hyperandrogenism (H), oligo/anovulation (O) and PCO appearance (P): phenotype A, H + O + P; phenotype B, H + O; phenotype C, H + P; phenotype D, O + P. Prevalence of MetS and MRP were compared among the four groups. Based on Natural Cholesterol Education Program Adult Treatment Panel III diagnostic criteria, MetS prevalence was higher in phenotypes A and B (29.6% and 34.5%) compared with the other phenotypes (10.0% and 8.3%; P < 0.001). Although the prevalence of obesity was similar, the number of patients with homeostatic model assessment insulin resistance index (HOMA-IR) >3.8 was significantly higher in androgenic PCOS phenotypes. After logistic regression analysis, visceral adiposity index (VAI) was the only independent predictor of MetS in PCOS (P = 0.002). VAI was also significantly higher in phenotype B, when compared with the others (P < 0.01). Phenotypes A and B had the highest risk of MetS among the four phenotypes, and VAI may be a predictor of metabolic risk in PCOS women. © 2016 Japan Society of Obstetrics and Gynecology.

Polycystic ovary syndrome is a common endocrinopathy characterized by oligo ovulation or anovulation, signs of androgen excess and multiple small ovarian cysts. It includes various metabolic abnormalities: insulin resistance, hyperinsulinemia, impaired glucose tolerance, visceral obesity, inflammation and endothelial dysfunction, hypertension and dyslipidemia. All these metabolic abnormalities have long-term implications. Treatment should be individualized and must not address a single sign or symptom. Studies are still needed to determine the benefits and the associated risks of the medication now available to practitioners.

Polycystic ovary syndrome (PCOS) is a complex disorder comprising both hormonal and metabolic abnormalities that include impaired glucose tolerance, type 2 diabetes, vascular disease, dyslipidemia, and obstructive sleep apnea. Insulin resistance is a central pathogenetic factor in PCOS that seems to result from a post-receptor-binding defect in insulin action. Insulin resistance and the consequent development of hyperinsulinemia contribute to the constellation of cardiometabolic abnormalities noted above. Although there is a paucity of data in regard to cardiovascular event rates and mortality in PCOS, an increased prevalence of cardiovascular risk factors has been well documented. Attention to the metabolic risks associated with PCOS, starting as early as adolescence, is essential to the medical care of these patients.

Polycystic ovary syndrome (PCOS) occurs in 6% to 10% of women and, as the most common worldwide endocrinopathy of reproductive-aged women, is linked to a constellation of reproductive and metabolic abnormalities, including anovulatory infertility, hirsutism, acne, and insulin resistance in association with metabolic syndrome. Despite a genetic component to PCOS, ethnicity plays an important role in the phenotypic expression of PCOS, with South Asian PCOS women having more severe reproductive and metabolic symptoms than other ethnic groups. South Asians with PCOS seek medical care at an earlier age for reproductive abnormalities; have a higher degree of hirsutism, infertility, and acne; and experience lower live birth rates following in vitro fertilization than do whites with PCOS. Similarly, South Asians with PCOS have a higher prevalence of insulin resistance and metabolic syndrome than do other PCOS-related ethnic groups of a similar body mass index. Inheritance of PCOS appears to have a complex genetic basis, including genetic differences based on ethnicity, which interact with lifestyle and other environmental factors to affect PCOS phenotypic expression. Obstetricians and Gynecologists, Family Physicians Learning Objectives: After completing this CME activity, physicians should be better able to state an ethnic difference in reproductive dysfunction between South Asian and white women with polycystic ovary syndrome (PCOS), state an ethnic difference in metabolic dysfunction between South Asian and white women with PCOS, identify a genetic abnormality found in South Asian women with PCOS, and list 2 environmental factors that predispose South Asian women to metabolic dysfunction.

The Androgen Excess and Polycystic Ovary Syndrome (AE-PCOS) Society created a panel to provide evidence-based reviews of studies assessing PCOS-CVD risk relationships and to develop guidelines for preventing CVD. An expert panel in PCOS and CVD reviewed literature and presented recommendations. Only studies comparing PCOS with control patients were included. All electronic databases were searched; reviews included individual studies/databases, systematic reviews, abstracts, and expert data. Articles were excluded if other hyperandrogenic disorders were not excluded, PCOS diagnosis was unclear, controls were not described, or methodology precluded evaluation. Inclusion/exclusion criteria were confirmed by at least two reviewers and arbitrated by a third. Systematic reviews of CVD risk factors were compiled and submitted for approval to the AE-PCOS Society Board. Women with PCOS with obesity, cigarette smoking, dyslipidemia, hypertension, impaired glucose tolerance, and subclinical vascular disease are at risk, whereas those with metabolic syndrome and/or type 2 diabetes mellitus are at high risk for CVD. Body mass index, waist circumference, serum lipid/glucose, and blood pressure determinations are recommended for all women with PCOS, as is oral glucose tolerance testing in those with obesity, advanced age, personal history of gestational diabetes, or family history of type 2 diabetes mellitus. Mood disorder assessment is suggested in all PCOS patients. Lifestyle management is recommended for primary CVD prevention, targeting low-density and non-high-density lipoprotein cholesterol and adding insulin-sensitizing and other drugs if dyslipidemia or other risk factors persist.

Obesity and polycystic ovary syndrome.

Obesity is now a major international health concern. It is increasingly common in young women with reproductive, metabolic and psychological health impacts. Reproductive health impacts are often poorly appreciated and include polycystic ovary syndrome (PCOS), infertility and pregnancy complications. PCOS is the most common endocrine condition in women and is underpinned by hormonal disturbances including insulin resistance and hyperandrogenism. Obesity exacerbates hormonal and clinical features of PCOS and women with PCOS appear at higher risk of obesity, with multiple underlying mechanisms linking the conditions. Lifestyle intervention is first line in management of PCOS to both prevent weight gain and induce weight loss; however improved engagement and sustainability remain challenges with the need for more research. Medications like metformin, orlistat, GLP1 agonists and bariatric surgery have been used with the need for large scale randomised clinical trials to define their roles.

To systematically review the impact of Yasmin (drospirenone pill) compares with other standard treatments for symptoms of Polycystic Ovary Syndrome (PCOS). The relevant studies of the randomized controlled trials in women with PCOS treated with drospirenone were retrieved and the systematic evaluation was conducted. Eighteen articles were included. Compared with drospirenone (DRSP) monotherapy, DRSP plus metformin was better in reducing body mass index (BMI), luteinizing hormone (LH) and low-density lipoprotein cholesterol (LDL-C). Compared with metformin, DRSP was better in modulating serum total testosterone (T), sex hormone-binding globulin (SHBG), follicle stimulating hormone (FSH) and free androgen index (FAI), while metformin was more effective in reducing BMI, total cholesterol (TC), LDL-C and Triglyceride (TG). DRSP was superior to cyproterone acetate (CPA) in reducing TC and homeostasis model assessment of insulin resistance (HOMA-IR). DRSP shows better effect in modulating LDL-C and high-density lipoprotein cholesterol (HDL-C) compared with desogestrel (DSG). The available data suggested that DRSP was effective in modulating hormones, insulin and lipid metabolism in women with PCOS. Compared with commonly used drugs for symptoms of PCOS as CPA and DSG, DRSP shows identical or better effect in improving symptoms and protect cardiovascular system. For the PCOS patients with IR, obesity or high LH/FSH ratio, DRSP combines with metformin maybe more effective than use DRSP alone. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

Polycystic ovary syndrome (PCOS) is a common heterogeneous endocrine disorder characterized by irregular menses, hyperandrogenism, and polycystic ovaries. The prevalence of PCOS varies depending on which criteria are used to make the diagnosis, but is as high as 15%-20% when the European Society for Human Reproduction and Embryology/American Society for Reproductive Medicine criteria are used. Clinical manifestations include oligomenorrhea or amenorrhea, hirsutism, and frequently infertility. Risk factors for PCOS in adults includes type 1 diabetes, type 2 diabetes, and gestational diabetes. Insulin resistance affects 50%-70% of women with PCOS leading to a number of comorbidities including metabolic syndrome, hypertension, dyslipidemia, glucose intolerance, and diabetes. Studies show that women with PCOS are more likely to have increased coronary artery calcium scores and increased carotid intima-media thickness. Mental health disorders including depression, anxiety, bipolar disorder and binge eating disorder also occur more frequently in women with PCOS. Weight loss improves menstrual irregularities, symptoms of androgen excess, and infertility. Management of clinical manifestations of PCOS includes oral contraceptives for menstrual irregularities and hirsutism. Spironolactone and finasteride are used to treat symptoms of androgen excess. Treatment options for infertility include clomiphene, laparoscopic ovarian drilling, gonadotropins, and assisted reproductive technology. Recent data suggest that letrozole and metformin may play an important role in ovulation induction. Proper diagnosis and management of PCOS is essential to address patient concerns but also to prevent future metabolic, endocrine, psychiatric, and cardiovascular complications.

2014-01-01

The prevalence of polycystic ovary syndrome (PCOS) and its distinct clinical phenotypes were assessed using 3 sets of international diagnostic criteria in women self-reporting concerns over outward features of PCOS. Revised ultrasonographic criteria for polycystic ovaries (PCO) based on modern ultrasound technology were used. Of the participants, 53%, 62%, and 70% were diagnosed with PCOS using National Institutes of Health, Androgen Excess and PCOS Society, and Rotterdam criteria, respectively. Prevalence of Frank, Ovulatory, Normoandrogenic, and Non-PCO PCOS were 66%, 13%, 11%, and 9%, respectively. Frank PCOS was associated with the severest metabolic disturbances whereas metabolic profiles in Normoandrogenic PCOS did not differ from controls, supporting reduced health risks in women without androgen excess. Metabolic disturbances and hyperandrogenism were linked to excess adiposity across all the groups. Using updated criteria for PCO, the prevalence of Non-PCO PCOS and PCO alone in healthy women recruited from the general population was reduced compared to the previous reports. PMID:24520081

Retinoids (retinol and its derivatives) are required for maintaining vision, immunity, barrier function, reproduction, embryogenesis, cell proliferation and differentiation. Furthermore, retinoid signaling plays a key role in initiating meiosis of germ cells of the mammalian fetal ovary. Recently, studies indicated that precise retinoid level regulation in the ovary provides a molecular control of ovarian development, steroidogenesis and oocyte maturation. Besides, abnormal retinoid signaling may be involved in the pathogenesis of polycystic ovary syndrome (PCOS), one of the most common ovarian endocrinopathies in reproductive-aged women worldwide. This review primarily summarizes recent advancements made in investigating the action of retinoid signaling in ovarian physiology as well as the abnormal retinoid signaling in PCOS. Copyright © 2017.

Hardy, Tristan S E; Norman, Robert J

2013-08-01

Polycystic ovary syndrome (PCOS) is the most common endocrinopathy affecting women of reproductive age and is increasingly recognized as a disorder manifesting in the peripubertal and adolescent period. Diagnosis in the adolescent is difficult due to the high background rate of menstrual irregularity, the high prevalence of polycystic ovarian morphology and hyperandrogenic features in this population. Recent guidelines suggest that menstrual irregularity for over two years, reduced reliance on ultrasound diagnosis of polycystic ovarian morphology, and accurate assessment of hyperandrogenic and metabolic features are suitable strategies for the diagnosis of PCOS in the adolescent. Accurate diagnosis is important given the long-term implications of the disorder, with increasing emphasis on metabolic sequelae. Copyright © 2013 Elsevier Inc. All rights reserved.

Polycystic ovary syndrome (PCOS) is the most common endocrine disorder occurring in women of childbearing age. The literature describes the relationship between PCOS and high blood pressure levels and increased risk of arterial hypertension development, which is an important and strong risk factor for adverse cardiovascular events in the future. Among the main causes of hypertension in PCOS women insulin resistance, hyperandrogenism, greater sympathetic nerve activity and concomitance of obesity are stressed. Because PCOS may contribute to earlier development of hypertension, as well as pre-hypertension, therefore it is advisable to monitor blood pressure systematically, to control known risk factors, and to initiate the treatment of hypertension when the disease occur.

Assessment of plasma prolidase levels in polycystic ovary syndrome (PCOS). PCOS patients were screened according to Rotterdam Criterion and prolidase levels were measured.  A total of 170 patients and 160 controls were recruited for the study and it was found that prolidase levels were significantly higher in PCOS group (991.10 ± 39.52) than control (621.89 ± 23.94). Furthermore it has been found that prolidase levels increase with the number of cysts in ovaries. Significant difference between prolidase levels in PCOS and control shows that it may be used as a diagnostic marker for disease. In addition to this, there is a positive correlation found between prolidase levels and number of cysts, hence may be used as a prognostic marker to monitor disease status.

Genes and proteins of the alternative steroid backdoor pathway for dihydrotestosterone synthesis are expressed in the human ovary and seem enhanced in the polycystic ovary syndrome.

Recently, dihydrotestosterone biosynthesis through the backdoor pathway has been implicated for the human testis in addition to the classic pathway for testosterone (T) synthesis. In the human ovary, androgen precursors are crucial for estrogen synthesis and hyperandrogenism in pathologies such as the polycystic ovary syndrome is partially due to ovarian overproduction. However, a role for the backdoor pathway is only established for the testis and the adrenal, but not for the human ovary. To investigate whether the backdoor pathway exists in normal and PCOS ovaries, we performed specific gene and protein expression studies on ovarian tissues. We found aldo-keto reductases (AKR1C1-1C4), 5α-reductases (SRD5A1/2) and retinol dehydrogenase (RoDH) expressed in the human ovary, indicating that the ovary might produce dihydrotestosterone via the backdoor pathway. Immunohistochemical studies showed specific localization of these proteins to the theca cells. PCOS ovaries show enhanced expression, what may account for the hyperandrogenism.

Setji, Tracy L; Brown, Ann J

2014-10-01

Polycystic ovary syndrome is now a well-recognized condition affecting 6%-25% of reproductive-aged women, depending on the definition. Over the past 3 decades, research has launched it from relative medical obscurity to a condition increasingly recognized as common in internal medicine practices. It affects multiple systems, and requires a comprehensive perspective on health care for effective treatment. Metabolic derangements and associated complications include insulin resistance and diabetes, hyperlipidemia, hypertension, fatty liver, metabolic syndrome, and sleep apnea. Reproductive complications include oligo-/amenorrhea, sub-fertility, endometrial hyperplasia, and cancer. Associated psychosocial concerns include depression and disordered eating. Additionally, cosmetic issues include hirsutism, androgenic alopecia, and acne. This review organizes this multi-system approach around the mnemonic "MY PCOS" and discusses evaluation and treatment options for the reproductive, cosmetic, and metabolic complications of this condition.

Objective To compare the prevalence of various metabolic and cardiovascular risk factors and insulin resistance between polycystic ovary syndrome (PCOS) patients with or without hyperandrogenism. Material and Methods This is a retrospective cross-sectional study involving women with PCOS as diagnosed according to the Androgen Excess (AE) Society definition (n=504) and women with normoandrogenemic PCOS (n=183). Anthropometrics, lipid profile, glucose, insulin, oral glucose tolerance test (OGTT), and reproductive hormone levels were evaluated. Results Women with PCOS diagnosed according to the AE Society had a significantly higher prevalence of metabolic syndrome compared with the normoandrogenemic PCOS phenotype: odds ratio (OR) 2.95 [95% confidence interval (CI) 1.21–7.21]. There was no significant difference in the prevalence glucose intolerance test between the groups [OR: 2.15, 95% CI 0.71–6.56]. The prevalence of low high density lipoprotein (HDL)-cholesterol in the group under the AE-PCOS Society criteria was higher than that of the normoandrogenemic PCOS group [OR: 2.82, 95%CI 1.29–3.36]. Conclusion The risks of metabolic syndrome and cardiovascular disease may vary among the phenotypes of PCOS based on the Rotterdam criteria. This new data may be of reference in informing women with PCOS, although further prospective studies are needed to validate this proposition. PMID:27990089

Polycystic ovary syndrome (PCOS) is a good example of obesity-related cardiovascular complication affecting young women. PCOS is not only considered a reproductive problem but rather represents a complex endocrine, multifaceted syndrome with important health implications. Several evidences suggest an increased cardiovascular risk of cardiovascular disease associated with this syndrome, characterized by an impairment of heart structure and function, endothelial dysfunction and lipid abnormalities. All these features, probably linked to insulin-resistance, are often present in obese PCOS patients. Cardiovascular abnormalities represent important long-term sequelae of PCOS that need further investigations.

This study compares the cycle characteristics of clomiphene (CC) with CC+HMG (Human Menopausal Gonadotropin or Menotropins) in Polycystic Ovary Syndrome (PCOS) and non-PCOS infertile patients. Patients were treated by CC + minimal HMg protocol. The cancellation rate, the mean number of different follicle sizes and endometrial thickness and pattern were compared. The cancelled cycles due to non-responsiveness were significantly higher in CC compared to CC+ minimal HMg protocol. PCOS patients are significantly nonresponsive in CC cycle and hyperresponsive in CC+ minimal HMg cycles. The mean number of different sizes of follicles and the endometrial thickness were significantly higher in CC+ minimal HMg. PCOS patients were significantly different from non-PCOS regarding the number of mature follicle and endometrial thickness. The pregnancy rate was 11% (10.2% in non-PCOS and 12.2% in PCOS). CC+ minimal HMg is a viable alternative to HMg /FSH only protocol in CC failure or resistant patients, and its efficacy can be mostly attributed to improvement of endometrial quality and increase in follicle number. Moreover, due to high cancellation of PCOS patients treated by this protocol, seemingly other alternatives should be found; perhaps sequential letrozole+HMg/FSH that have been shown to improve the ovarian response in this group of patients.

It has been shown that there is an increase in oxidative stress in polycystic ovary syndrome (PCOS). Statins are considered to have a pleiotropic effect other than their lipid-lowering effect. These effects may be mediated in part by reducing oxidative stress. This randomized, double-blind, placebo-controlled study was conducted to assess the effect of atorvastatin on serum malondialdehyde (MDA) concentrations as a marker of oxidative stress in patients with PCOS. Forty medication-naïve patients with PCOS were randomized to either atorvastatin 20 mg daily or placebo for 3 months. A 3-month extension study for both groups of patients was undertaken with metformin 1500 mg daily after completing initial 3 months of atorvastatin or placebo. There was a significant decrease of MDA concentrations with atorvastatin [mean (sem)] [0.29 (0.04) vs. 0.25 (0.02) μmol/liter; P < 0.01] compared with placebo [0.28 (0.02) vs. 0.29 (0.12) μmol/liter; P = 0.52]. Three months treatment with metformin resulted in further reduction of MDA levels with atorvastatin compared with baseline [0.25 (0.02) baseline vs. 0.23 (0.03) μmol/liter for atorvastatin treated; P = 0.02]. There was also a significant correlation between the reduction in MDA with a reduction in high-sensitivity C-reactive protein (r = 0.71, P < 0.01), an increase in 25-hydroxyvitamin D (25OHD; r = -0.68, P = 0.02), and a reduction in testosterone levels (r = 0.63, P = 0.01). Multiple linear regression analysis revealed Δ25OHD, ΔC-reactive protein, and Δtestosterone were independent predictors of changes in MDA after atorvastatin treatment. No correlation was observed between the reductions in serum MDA concentrations with changes in the lipid parameters. Twelve weeks of atorvastatin led to a significant reduction in oxidative stress as determined by MDA concentrations among patients with polycystic ovary syndrome that was independently predicted by changes in testosterone, 25OHD, and high-sensitivity C

Polycystic ovary syndrome (PCOS) is characterized by hyperandrogenism, oligo-/anovulation, and polycystic ovarian morphology and is a complex endocrine disorder that also presents with features of the metabolic syndrome, including obesity, insulin resistance, and dyslipidemia. These latter symptoms form cardiometabolic risk factors predisposing individuals to the development of type 2 diabetes and cardiovascular disease (CVD). To date, animal models to study PCOS in the context of the metabolic syndrome and CVD risk have been lacking. The aim of this study was to investigate the JCR:LA-cp rodent as an animal model of PCOS associated with the metabolic syndrome. Metabolic indices were measured at 6 and 12 wk, and reproductive parameters including ovarian morphology and estrous cyclicity were assessed at 12 wk or adulthood. At 6 wk of age, the cp/cp genotype of the JCR:LA-cp strain developed visceral obesity, insulin resistance, and dyslipidemia (hypertriglyceridemia and hypercholesterolemia) compared with control animals. Serum testosterone concentrations were not significantly different between groups at 6 wk of age. However, at 12 wk, the cp/cp genotype had higher serum testosterone concentrations, compared with control animals, and presented with oligoovulation, a decreased number of corpora lutea, and an increased number of total follicles, in particular atretic and cystic follicles. The cardiometabolic risk factors in the cp/cp animals were exacerbated at 12 wk including obesity, insulin resistance, and dyslipidemia. The results of this study demonstrate that the JCR:LA-cp rodent may be a useful PCOS-like model to study early mechanisms involved in the etiology of cardiometabolic risk factors in the context of both PCOS and the metabolic syndrome.

The detailed molecular mechanism of Bmovo-1 regulation of ovary size is unclear. To uncover the mechanism of Bmovo-1 regulation of ovarian development and oogenesis using RNA-Seq, we compared the transcriptomes of wild type (WT) and Bmovo-1-overexpressing silkworm (silkworm+Bmovo-1) ovaries. Using a pair-end Illumina Solexa sequencing strategy, 5,296,942 total reads were obtained from silkworm+Bmovo-1 ovaries and 6,306,078 from WT ovaries. The average read length was about 100 bp. Clean read ratios were 98.79% for silkworm+Bmovo-1 and 98.87% for WT silkworm ovaries. Comparative transcriptome analysis showed 123 upregulated and 111 downregulated genes in silkworm+Bmovo-1 ovaries. These differentially expressed genes were enriched in the extracellular and extracellular spaces and involved in metabolism, genetic information processing, environmental information processing, cellular processes and organismal systems. Bmovo-1 overexpression in silkworm ovaries might promote anabolism for ovarian development and oogenesis and oocyte proliferation and transport of nutrients to ovaries by altering nutrient partitioning, which would support ovary development. Excessive consumption of nutrients for ovary development alters nutrient partitioning and deters silk protein synthesis. PMID:26643037

Metabolic disturbances are common features of polycystic ovary syndrome (PCOS), which possibly enhance the risk of diabetes and cardiovascular disease. Lipid accumulation product (LAP) is an emerging cardiovascular risk factor. The aim of this study was to explore the ability of LAP to identify metabolic syndrome (MS) in PCOS women. In a cross-sectional study, anthropometric, biochemical and clinical parameters were measured in 105 PCOS women. Receiver operating characteristic (ROC) analysis was used to find out the cut-off points of LAP to predict MS. MS was categorized according to International Diabetes Federation (IDF) criteria. The prevalence of MS was 43.8% in this study. PCOS women with MS had significantly higher LAP levels compared to those without MS. LAP was highly correlated with components of MS. ROC analysis showed that LAP was a significant discriminator for MS in PCOS women, and the optimal cutoff point of LAP to predict MS was 54.2 (93.3% sensitivity, 96.7% specificity). LAP seems to be associated with MS and has a strong and reliable diagnostic accuracy for MS in PCOS women. © J. A. Barth Verlag in Georg Thieme Verlag KG Stuttgart · New York.

To measure the vascularization and ovarian volume with three-dimensional sonography in patients diagnosed of polycystic ovary syndrome with stimulated ovulation treatment, and to analyse the differences between the patients treated with clomiphen citrate versus clomiphen citrate and metformin. Therty patients were studied. Twenty ovulation cycles were obtained with clomiphen citrate and 17 with clomiphen citrate plus merformin (added in case of obesity or hyperglucemy/hyperinsulinemia). Ovarian volumes and vascular indexes were studied with 3D-sonography and results were analysed by treatment. There were no statistical differences of ovarian volume by treatment along the cycles, although bigger volume were found in ovulatory cycles compared to non-ovulatory ones (20,36 versus 13,89 ml, p = 0,026). No statistical differences were also found concerning vascular indexes, neither by treatment nor by the obtention of ovulation in the cycle. Ovarian volume and vascular indexes measured with three-dimensional sonography in patients diagnosed of polycystic ovary syndrome do not show differents values in patients treated with clomiphen citrate alone versus clomiphen citrate plus metformin.

Polycystic ovary syndrome (PCOS) is a complex and heterogeneous endocrine disorder. To understand the pathogenesis of PCOS, we established rat models of PCOS induced by letrozole and employed deep sequencing to screen the differential expression of microRNAs (miRNAs) in PCOS rats and control rats. We observed vaginal smear and detected ovarian pathological alteration and hormone level changes in PCOS rats. Deep sequencing showed that a total of 129 miRNAs were differentially expressed in the ovaries from letrozole-induced rat model compared with the control, including 49 miRNAs upregulated and 80 miRNAs downregulated. Furthermore, the differential expression of miR-201-5p, miR-34b-5p, miR-141-3p, and miR-200a-3p were confirmed by real-time polymerase chain reaction. Bioinformatic analysis revealed that these four miRNAs were predicted to target a large set of genes with different functions. Pathway analysis supported that the miRNAs regulate oocyte meiosis, mitogen-activated protein kinase (MAPK) signaling, phosphoinositide 3-kinase/Akt (PI3K-Akt) signaling, Rap1 signaling, and Notch signaling. These data indicate that miRNAs are differentially expressed in rat PCOS model and the differentially expressed miRNA are involved in the etiology and pathophysiology of PCOS. Our findings will help identify miRNAs as novel diagnostic markers and therapeutic targets for PCOS.

New biomarkers for diagnosis and management of polycystic ovary syndrome.

Polycystic ovary syndrome (PCOS) is the most common endocrine disorder affecting young women. Even though the definition of PCOS has changed over the years, all diagnostic criteria include two or more of the following: oligomenorrhea/oligoovulation/anovulation, androgen excess and polycystic ovaries (PCO). Traditional method of assessing the ovarian morphology has been transvaginal pelvic ultrasound. Recent studies support that serum anti-Mullerian hormone (AMH) levels correlate with the number of ovarian follicles and cysts. Hence, measurement of AMH is adequate to make the diagnosis. Traditionally, hyperandrogenemia has been assessed by measuring total-testosterone. The literature stresses the importance of sex hormone binding globulin (SHBG) measurements and bioavailable-testosterone and free-testosterone calculations, because insulin resistance decreases SHBG, lowers total-testosterone, and leads to under-estimation of bioavailable- and free-testosterone. Since 50-60% of PCOS patients have metabolic syndrome, assessment of metabolic risk is also necessary. It is important to diagnose insulin resistance before development of glucose intolerance and diabetes. This requires measurements of not only plasma glucose but also insulin concentrations. Determination of HgBA1 can be informative as well. This review aims to present an accurate and cost-effective approach to diagnosis and management of PCOS. Copyright © 2017 Elsevier B.V.

To summarize promising areas of investigation into polycystic ovary syndrome (PCOS) and to stimulate further research in this area. Summary of a conference held by international researchers in the field of polycystic ovary syndrome. Potential areas of further research activity include the analysis of predisposing conditions that increase the risk of PCOS, particularly genetic background and environmental factors, such as endocrine disruptors and lifestyle. The concept that androgen excess may contribute to insulin resistance needs to be re-examined from a developmental perspective, since animal studies have supported the hypothesis that early exposure to modest androgen excess is associated with insulin resistance. Defining alterations of steroidogenesis in PCOS should quantify ovarian, adrenal and extraglandular contribution, as well as clearly define blood reference levels by some universal standard. Intraovarian regulation of follicle development and mechanisms of follicle arrest should be further elucidated. Finally, PCOS status is expected to have long-term consequences in women, specifically the development of type 2 diabetes, cardiovascular diseases and hormone dependent cancers. Identifying susceptible individuals through genomic and proteomic approaches would help to individualize therapy and prevention. There are several intriguing areas for future research in PCOS. A potential limitation of our review is that we focused selectively on areas we viewed as the most controversial. © 2011 Blackwell Publishing Ltd.

To investigate the prevalence of metabolic syndrome in clomiphene citrate (CC) resistant polycystic ovary syndrome (PCOS) patients. 58 CC resistant PCOS patients, 52 CC responders, 53 fertile PCOS and 53 age and body mass index-matched normoandrogenic ovulatory fertile women were evaluated for metabolic syndrome. Metabolic syndrome prevalence was 41.4% in CC resistants, in 23.1% of CC responders, in 11.3% of PCOS fertiles and 0% of controls (p < 0.0001). Waist circumference (WC) > 88 cm was 44.8%, systolic blood pressure (BP) ≥ 130 mmHg and diastolic BP ≥85 mmHg were 27.6%, TG (triglyceride) ≥150 mg/dL was 36.2%, HDL(high density lipoprotein) < 50 mg/dL was 63.8%, fasting glucose levels ≥ 100 mg/dL was 20.7% in CC resistant PCOS women. There were positive associations between CC resistance and WC >88 cm, BP ≥ 130 ≥ 85 mmHg, TG ≥ 150 mg/dL, HDL < 50 mg/dL, fasting glucose ≥ 100 mg/dL, and presence of metabolic syndrome (p < 0.05, for all). Moreover, WC > 88 cm, and HDL < 50 mg/dL were independent variables that were associated by CC resistance by multivariate regression analysis. CC resistant PCOS patients have high prevalence of metabolic syndrome. These women have an increased risk of future cardiovascular disease.

To investigate the different characteristics in Chinese Han women with polycystic ovary syndrome, and to analyze the significance of hyperandrogenism in insulin resistance and other metabolic profiles. A cross-sectional study. Medical university hospital. A total of 229 women with polycystic ovary syndrome aged 18-45 years. Women with polycystic ovary syndrome, diagnosed by Rotterdam criteria, were divided into four groups according to the quartile intervals of free androgen index levels. Comparisons between groups were performed using one-way analysis of variance. Stepwise logistic regression analysis was performed to investigate the association between homeostasis model assessment-insulin resistance and independent variables. Within the four phenotypes, women with phenotype 1 (hyperandrogenism, oligo/anovulation, and polycystic ovaries) exhibited higher total testosterone, free androgen index, androstenedione, low-density lipoprotein, and lower quantitative insulin sensitivity check index (p < 0.05); women with phenotype 4 (oligo/anovulation and polycystic ovaries) showed lower total cholesterol, low-density lipoprotein, and homeostasis model assessment-insulin resistance, but higher high-density lipoprotein (p < 0.05). The levels of triglycerides, total cholesterol, low-density lipoprotein, and homeostasis model assessment-insulin resistance significantly increased, but high-density lipoprotein and quantitative insulin sensitivity check index decreased with the elevation of free androgen index intervals. After adjustment for lipid profiles, free androgen index was significantly associated with homeostasis model assessment-insulin resistance in both lean and overweight/obese women (odds ratio 1.302, p = 0.039 in lean vs. odds ratio 1.132, p = 0.036 in overweight/obese). Phenotypes 1 and 4 represent groups with the most and least severe metabolic profiles, respectively. Hyperandrogenism, particularly with elevated free androgen index, is likely a key contributing

Adolescence is a time of rapidly changing reproductive hormones and menstrual patterns making diagnosis of polycystic ovary syndrome (PCOS) challenging in this population. Nonetheless, there is significant concern that the metabolic and reproductive abnormalities that emerge at adolescence associated with a diagnosis of PCOS have lifelong implications for the individual. There are limited data available on the best treatments for the adolescent with PCOS. The focus of treatment is often best served by attention to the individual abnormalities such as menstrual dysfunction, symptoms of androgen excess such as hirsutism and acne, possible metabolic dysfunction primarily seen with concurrent obesity, and concerns related to self-image and mood disorders.

Polycystic ovary syndrome is a heterogeneous endocrine disorder that affects reproductive-age women. The mechanisms underlying the endocrine heterogeneity and neuroendocrinology of polycystic ovary syndrome are still unclear. In this study, we investigated the expression of the kisspeptin system and gonadotropin-releasing hormone pulse regulators in the hypothalamus as well as factors related to luteinizing hormone secretion in the pituitary of polycystic ovary syndrome rat models induced by testosterone or estradiol. A single injection of testosterone propionate (1.25 mg) (n=10) or estradiol benzoate (0.5 mg) (n=10) was administered to female rats at 2 days of age to induce experimental polycystic ovary syndrome. Controls were injected with a vehicle (n=10). Animals were euthanized at 90-94 days of age, and the hypothalamus and pituitary gland were used for gene expression analysis. Rats exposed to testosterone exhibited increased transcriptional expression of the androgen receptor and estrogen receptor-β and reduced expression of kisspeptin in the hypothalamus. However, rats exposed to estradiol did not show any significant changes in hormone levels relative to controls but exhibited hypothalamic downregulation of kisspeptin, tachykinin 3 and estrogen receptor-α genes and upregulation of the gene that encodes the kisspeptin receptor. Testosterone- and estradiol-exposed rats with different endocrine phenotypes showed differential transcriptional expression of members of the kisspeptin system and sex steroid receptors in the hypothalamus. These differences might account for the different endocrine phenotypes found in testosterone- and estradiol-induced polycystic ovary syndrome rats.

To evaluate the effects of in vitro maturation and fertilization of oocytes from unstimulated ovaries in infertile women with polycystic ovary syndrome (PCOS). Retrospective study. Reproductive Medicine Center, First Affiliated Hospital of Wenzhou Medical College, People's Republic of China. One hundred eighteen women with PCOS undergoing 152 cycles of in vitro maturation treatment. Oocyte retrieval was carried out by ultrasound-guided puncture on days 9-14 of the cycle. The oocytes were cultured in vitro using maturation culture medium, which consisted of M-199 + 20% fetal bovine serum (FBS) + 75 mIU/mL recombinant FSH +/- 0.5 IU/mL hCG. After the oocytes had matured in vitro, fertilization and embryo transfer were performed. Rates of clinical pregnancy, multiple pregnancies, and live birth. Relatively optimal laboratory results were obtained in this study. Embryo transfer was performed in 140 cycles, with a clinical pregnancy rate (PR) of 40.0% per transfer. Fifty-six babies have been born and there are 10 ongoing pregnancies. The overall multiple PR was 33.93%. Our results show that using in vitro matured oocytes from unstimulated ovaries could be offered as an alternative to conventional IVF in women with PCOS, and future work should address ways to decrease the incidence of multiple pregnancies.

Polycystic ovary syndrome (PCOS), also clinically known as Stein-Leventhal syndrome, is an endocrine disorder that affects 5-10% of women. To evaluate the risk factors for developing early onset of cardiovascular disease (CVD) in young patients with PCOS from our local population. Case-control study. Fifty women with PCOS selected by history and transvaginal ultrasounds and 30 age-matched healthy women (controls). The case subjects and controls were further divided into two age categories comprising of equal number of subjects, of 20-29 and 30-39 years of age. The subjects underwent a detailed medical history, general physical examination, systolic (SBP) and diastolic blood pressures (DBP). Fasting blood samples were analyzed for glucose, insulin, triacylglycerides (TAG), total cholesterol, high density lipoprotein-C (HDL-C), low density lipoprotein-C (LDL-C), follicle-stimulating hormone (FSH), and luteinizing hormone (LH). Women with the PCOS had significantly higher mean arterial pressure (MAP), serum TAG, LDL-C, insulin, and LH levels when compared with the age-matched control subjects. No significant differences were observed between serum cholesterol, glucose, and FSH levels between cases and controls. However, no marked differences were observed in biochemical parameters between the two age groups of PCOS patients. Younger women with PCOS are equally at risk of developing CVD as older women.

In order to develop a medical alternative to surgical ovarian diathermy (OD) in polycystic ovary syndrome (PCOS) more mechanistic information is required about OD. We therefore studied the cellular, molecular and vascular effects of diathermy on the ovary using an established ovine model of PCOS. Pregnant sheep were treated twice weekly with testosterone propionate (100 mg) from day 30-100 gestation. Their female offspring (n = 12) were studied during their second breeding season when the PCOS-like phenotype, with anovulation, is fully manifest. In one group (n = 4) one ovary underwent diathermy and it was collected and compared to the contralateral ovary after 24 hours. In another group a treatment PCOS cohort underwent diathermy (n = 4) and the ovaries were collected and compared to the control PCOS cohort (n = 4) after 5 weeks. Ovarian vascular indices were measured using contrast-enhanced ultrasound and colour Doppler before, immediately after, 24 hours and five weeks after diathermy. Antral follicles were assessed by immunohistochemistry and ovarian stromal gene expression by quantitative RT-PCR 24 hours and 5 weeks after diathermy. Diathermy increased follicular atresia (P<0.05) and reduced antral follicle numbers after 5 weeks (P<0.05). There was an increase in stromal CCL2 expression 24 hours after diathermy (P<0.01) but no alteration in inflammatory indices at 5 weeks. Immediately after diathermy there was increased microbubble transit time in the ovarian microvasculature (P = 0.05) but this was not seen at 24 hours. However 24 hours after diathermy there was a reduction in the stromal Doppler blood flow signal (P<0.05) and an increased ovarian resistance index (P<0.05) both of which persisted at 5 weeks (P<0.01; P<0.05). In the ovine model of PCOS, OD causes a sustained reduction in ovarian stromal blood flow with an increased ovarian artery resistance index associated with atresia of antral follicles.

The aim of this study was to investigate the clinical, endocrine, metabolic features and prevalence of metabolic syndrome (MBS) in Turkish adolescents with polycystic ovary syndrome (PCOS) and the differences in metabolic parameters between adolescent PCOS with or without the presence of polycystic ovaries (PCO) on ultrasound. Subjects (n = 77) were classified into two groups: oligomenorrhea (O) and clinical and/or biochemical hyperandrogenism (HA) (n = 38), without PCO and O + HA with PCO (n = 39). The control group consisted of 33 age-matched adolescents. Adolescents with PCOS had a significantly higher body mass index (BMI), waist circumference and levels of LH, LH/FSH ratio, triglyceride, insulin, HOMA-IR, free androgen index and lower levels of SHBG and FSH. After adjustment for BMI, LH, LH: FSH ratio remained significantly higher. Adolescents with PCOS had a higher prevalence of MBS. No significant differences in lipid profiles, insulin levels and insulin sensitivity in both the PCOS groups were seen. HDL-C levels were lower in the O + HA + PCO group compared to the controls. BMI may be the major contributing factor in the development of metabolic abnormalities in adolescents with PCOS. Impact statement Many studies have investigated the effect of PCOS on metabolic and cardiovascular risks. It is thought that PCOS increases metabolic and cardiovascular risks. Increase in metabolic and cardiovascular risks associated with PCOS may be handled with early diagnosis and early intervention of PCOS in adolescents, although the diagnosis of PCOS in adolescents could be hard because of the features of PCOS overlapping normal pubertal physiological events. However, early identification of adolescent girls with PCOS may provide opportunities for prevention of well-known health risks associated with this syndrome and reduction of long-term health consequences of PCOS by reducing androgen levels and improving metabolic profile.

Hillard, Paula J Adams

2005-09-01

Appropriate management of polycystic ovary syndrome in adolescents depends on recognizing the syndrome, which can have a variety of presenting complaints and must be differentiated from other causes of hyperandrogenism, as well as not dismissed as "normal adolescence." Oral contraceptives have long been considered the first line of treatment by obstetrician/gynecologists and have many advantages in treating the aspects of PCOS that are most bothersome to teens. Because of the potential risk for cardiovascular disease, early diagnosis and management may be helpful in minimizing the risk of the early metabolic correlates of adult disease.

The purpose of this study was to investigate chronic inflammation in the peripheral blood and ovaries of patients with polycystic ovary syndrome (PCOS). 86 PCOS patients and 50 controls were randomly enrolled in the study. Serum follicle stimulating hormone (FSH), luteinizing hormone (LH), testosterone (T), blood routine test, lipid metabolism index, inflammation cytokines were detected. Ovary samples from PCOS group and control group were collected for macrophage and lymphocyte immunohistochemistry staining. Patients with PCOS showed significantly higher serum CRP, lymphocytes, monocytes, eosinophilic granulocytes, as well as higher triglycerides (TG), TNF-α and IL-6. PCOS ovary had greater number of macrophages and lymphocytes immersed throughout. In conclusion, PCOS patients exhibited hypertriglyceridemia and chronic inflammation, with elevated peripheral lymphocytes, monocytes, and eosinophilic granulocytes. In addition, their ovaries showed persistent chronic inflammation with a larger number of inflammatory cells immersed. Copyright © 2011 Elsevier Ireland Ltd. All rights reserved.

MANAGEMENT OF ENDOCRINE DISEASE: Morbidity in polycystic ovary syndrome.

PubMed

Glintborg, Dorte; Andersen, Marianne

2017-02-01

Polycystic ovary syndrome (PCOS) is the most prevalent endocrine condition in premenopausal women. The syndrome is characterized by hyperandrogenism, irregular menses and polycystic ovaries when other etiologies are excluded. Obesity, insulin resistance and low vitamin D levels are present in more than 50% patients with PCOS, these factors along with hyperandrogenism could have adverse effects on long-term health. Hyperinflammation and impaired epithelial function were reported to a larger extent in women with PCOS and could particularly be associated with hyperandrogenism, obesity and insulin resistance. Available data from register-based and data linkage studies support that metabolic-vascular and thyroid diseases, asthma, migraine, depression and cancer are diagnosed more frequently in PCOS, whereas fracture risk is decreased. Drug prescriptions are significantly more common in PCOS than controls within all diagnose categories including antibiotics. The causal relationship between PCOS and autoimmune disease represents an interesting new area of research. PCOS is a lifelong condition and long-term morbidity could be worsened by obesity, sedentary way of life, Western-style diet and smoking, whereas lifestyle intervention including weight loss may partly or fully resolve the symptoms of PCOS and could improve the long-term prognosis. In this review, the possible implications of increased morbidity for the clinical and biochemical evaluation of patients with PCOS at diagnosis and follow-up is further discussed along with possible modifying effects of medical treatment. © 2017 European Society of Endocrinology.

To compare the effectiveness of clomifene citrate plus metformin and clomifene citrate plus placebo in women with newly diagnosed polycystic ovary syndrome. Randomised clinical trial. Multicentre trial in 20 Dutch hospitals. 228 women with polycystic ovary syndrome. Clomifene citrate plus metformin or clomifene citrate plus placebo. The primary outcome measure was ovulation. Secondary outcome measures were ongoing pregnancy, spontaneous abortion, and clomifene resistance. 111 women were allocated to clomifene citrate plus metformin (metformin group) and 114 women were allocated to clomifene citrate plus placebo (placebo group). The ovulation rate in the metformin group was 64% compared with 72% in the placebo group, a non-significant difference (risk difference - 8%, 95% confidence interval - 20% to 4%). There were no significant differences in either rate of ongoing pregnancy (40% v 46%; - 6%, - 20% to 7%) or rate of spontaneous abortion (12% v 11%; 1%, - 7% to 10%). A significantly larger proportion of women in the metformin group discontinued treatment because of side effects (16% v 5%; 11%, 5% to 16%). Metformin is not an effective addition to clomifene citrate as the primary method of inducing ovulation in women with polycystic ovary syndrome.

The superficial ovarian cortex constitutes the micro-environment where resting and early growing follicles reside. As small follicles do not possess an independent capillary network, both their survival and early growth depend on their proximity to the cortical vessels. Little is known about the possible changes in superficial ovarian cortex vascularization in normal women throughout reproductive life or in pathological conditions such as polycystic ovary syndrome (PCOS) involving abnormal early follicle growth. We studied the vascularization of the superficial and deep cortical stroma (DCS) in normal cycling ovaries from 21 to 50 years of age and in infertile women with PCOS. We used archival ovarian samples and specific CD34 immunostaining to determine blood vessel density and to analyse correlation with age and with the ovarian follicle reserve. Normal cycling ovaries showed an age-related increase in the superficial cortical stroma vascularization that was inversely correlated with the density of small (primordial and primary) follicles. In contrast, blood vessel density in the DCS significantly decreased in women aged >or=40 years. Ovaries from PCOS showed a 2-fold increase in blood vessel density in both superficial cortical stroma and DCS with respect to age-matched controls. The increased vascularization of the superficial cortical stroma in normal ovaries in relation to age and in ovaries from PCOS could have profound effects on cortical metabolic rate, primordial follicle survival/activation and early follicle growth, and may underline changes in follicle dynamics in mid-aged women and in PCOS.

Polycystic ovary syndrome (PCOS) is linked with metabolic syndrome, which includes obesity, insulin resistance, dyslipidemia, and endocrine function in patients with PCOS. The aim of this study was to determine the prevalence of adolescent PCOS and characteristics associated with PCOS in adolescents in Babol, Iran. A cross-sectional study was conducted on 1549 girl high school students aged 16-20 years who were living in Iran. After overnight fasting, blood samples were collected to determine hormones and lipid levels in PCOS patients between the first and fifth days of their menstrual period or withdrawal bleeding. The overall prevalence of adolescent PCOS was 129 (8.3%) (95% CI; 4.0, 12.0). Irregular menstruation was observed in 24.1% of adolescents. A total of 68% of PCOS adolescents had insulin resistance. Compared with non-PCOS adolescents, the OR of adolescent PCOS for family history of hirsutism was 1.53 (95% CI, 1.06-2.20; p=0.024), family history of irregular menstrual cycle was 2.27 (95% CI, 1.56-3.30; p<0.001), menarche age <13 years was 1.95 (95% CI, 1.36-2.81; p<0.001), hirsutism was 1.14 (CI 95%, 1.10-1.17; p<0.001), acne was 5.10 (CI 95%, 3.52-7.40; p<0.001), and wrist circumference was 1.28 (CI 95%, 1.07-1.54; p=0.007). The presenting findings showed the high prevalence of PCOS among Iranian adolescents. Emphasis should be placed on clinical screening in adolescents with high-risk factors, including irregular menstrual, menarche <13 years, hirsutism, acne, high wrist circumference, and paternal obesity to help reduce the risk of developing metabolic disturbance and to find ways to improve long-term health.

Insulin and the polycystic ovary syndrome.

Macut, Djuro; Bjekić-Macut, Jelica; Rahelić, Dario; Doknić, Mirjana

2017-08-01

Polycystic ovary syndrome (PCOS) is the most prevalent endocrinopathy among women during reproductive age. PCOS is characterised by hyperandrogenaemia, hyperinsulinaemia, and deranged adipokines secretion from the adipose tissue. In addition to the reduced insulin sensitivity, PCOS women exhibit β-cell dysfunction as well. Low birth weight and foetal exposure to androgens may contribute to the development of the PCOS phenotype during life. Further metabolic complications lead to dyslipidaemia, worsening obesity and glucose tolerance, high prevalence of metabolic syndrome, and greater susceptibility to diabetes. PCOS women show age-related existence of hypertension, and subtle endothelial and vascular changes. Adverse reproductive outcomes include anovulatory infertility, and unrecognised potentiation of the hormone-dependent endometrial cancer. The main therapeutic approach is lifestyle modification. Metformin is the primary insulin-sensitising drug to be used as an adjuvant therapy to lifestyle modification in patients with insulin resistance and impaired glucose tolerance, as well as in those referred to infertility treatment. Thiazolidinediones should be reserved for women intolerant of or refractory to metformin, while glucagon-like peptide 1 analogues has a potential therapeutic use in obese PCOS women. Randomised clinical trials and repetitive studies on different PCOS phenotypes for the preventive actions and therapeutic options are still lacking, though. Copyright © 2017 Elsevier B.V.

Polycystic ovary syndrome (PCOS) is the most prevalent endocrinopathy in women of reproductive age. The study was commenced to assess the favorable effects of Rutin against metabolic, biochemical, histological, and androgenic aspects of polycystic ovary syndrome in rats. Female Sprague-Dawley rats were administered letrozole (1 mg/kg) per orally (p.o) for a period of 21 days for the induction of PCOS, followed by dose of rutin (100 mg/kg and 150 mg/kg, p.o) for 15 days using 0.5% w/v CMC as vehicle. Metformin was also given as a standard control to one of the rat groups. Serum estradiol, progesterone, testosterone, serum lipid parameters, CRP and glucose levels were evaluated. Furthermore, antioxidant activity was tested using superoxide dismutase, catalase, glutathione per-oxidase and reactive-oxygen species level. Rutin flavonoid had a dose-dependent effect on androgenic levels depicting more recovery in the rutin-I treated group, while rutin-II treated groups showed better antioxidant and lipid profiles as compared with PCOS groups. A decrease in the value of C reactive protein (CRP) and a restoration in the proportion of estrous phase smears were observed in the rutin treated groups. Histopathological examination of ovary revealed a significant decrease in the number of cystic follicles in post treated groups. The effects observed with rutin were moderately similar to that with standard metformin, a widely used treatment drug for PCOS. The study provides evidence for the potential ameliorative effects of rutin against clinical and biochemical features of PCOS.

The role of ovarian surgery in polycystic ovary syndrome.

PubMed

Farquhar, Cynthia M

2004-10-01

Problems in inducing ovulation in women with polycystic ovary syndrome (PCOS) and anovulation are well recognized. In 1935, Stein and Leventhal first described surgical treatment by ovarian wedge resection at laparotomy for women with anovulation and PCOS. Ovarian wedge resection was eventually abandoned because of the significant risk of postsurgical adhesion formation, which resulted in tubal adhesions, and because of the advent of medical ovulation induction with clomiphene and gonadotrophins. However, since the arrival of minimally invasive surgical techniques, laparoscopic ovarian surgery has become feasible. The potential advantages of laparoscopic ovarian surgery include repeated single ovulations and less adhesion formation. Lowered costs make ovarian surgery an attractive alternative to gonadotrophins. However, although many case series have suggested that ovarian surgery is an effective strategy, few randomized, controlled trials have been undertaken comparing the success rates of surgery with gonadotrophins. The long-term concerns with surgery include adhesion formation and premature ovarian failure.

Environmental determinants of polycystic ovary syndrome.

In this review, we summarize existing research on a variety of environmental factors potentially involved in the etiology, prevalence, and modulation of polycystic ovary syndrome (PCOS), and we suggest avenues for future research. The main environmental factors we consider include environmental toxins, diet and nutrition, socioeconomic status, and geography. There is some evidence that environmental toxins play a role in disrupting reproductive health, but there is limited research as to how these toxins may affect the development of PCOS. Although research has also shown that PCOS symptoms are reduced with certain dietary supplements and with weight loss among obese women, additional research is needed to compare various approaches to weight loss, as well as nutritional factors that may play a role in preventing or mitigating the development of PCOS. Limited studies indicate some association of low socioeconomic status with certain PCOS phenotypes, and future research should consider socioeconomic conditions during childhood or adolescence that may be more relevant to the developmental onset of PCOS. Finally, the limited scope of comparable international studies on PCOS needs to be addressed, because global patterns of PCOS are potentially valuable indicators of cultural, environmental, and genetic factors that may contribute to excess risk in certain regions of the world.

Female Wistar rats were subcutaneously injected with 2.5 mg/kg testosterone propionate (Their female offspring were randomly divided into the medication group and the model group, 10 in each.) or neutral tea oil of the same dose (Ten female offspring was taken as the control group.) on the 16th day of pregnancy, once daily, for 3 successive days. BHC was given to rats in the medication group by gastrogavage, while equal volume of distilled water was given to rats in the model group and the control group by gastrogavage, both once daily for 20 successive days. The body weight and ovary weight were weighed to calculate the ratio of wet fat weight/body weight. The blood glucose levels were detected at 0, 0.5, 1, and 2 h using oral glucose tolerance test (OGTT). The serum concentrations of high-density lipoprotein cholesterol (HDL-C), triglyceride (TG), fasting blood glucose (FBG), and insulin were detected to calculate homeostasis model assessment of insulin resistance (HOMA-IR). The expressions of protein kinase B (AKT2), glycogen synthase kinase-3beta (GSK3beta), glucose transporter-4 (GLUT4), extracellular signal regulated kinase-1 (ERK1) protein, P-AKT2, P-GSK3beta, and P-ERK1 in ovaries were detected using Western blot. Compared with the control group, the ratio of wet fat weight/ body weight, the blood glucose levels at 0.5 and 2 h in OGTT, and HOMA-IR all obviously increased, and the HDL-C level obviously decreased in the model group (P < 0.05). Compared with the model group, the ratio of wet fat weight/body weight and the blood glucose levels at 2 h in OGTT obviously decreased, and the HDL-C level obviously increased in the medication group (P < 0.05). The expressions of AKT2, P-AKT2, GSK3beta, P-GSK3beta, GLUT4, and ERK1 in the ovary tissue were obviously

Our objective was to compare the effectiveness of metformin plus clomiphene citrate vs. gonadotrophins, laparoscopic ovarian diathermy, aromatase inhibitors, N-acetyl-cysteine and other insulin sensitizers+clomiphene for improving fertility outcomes in women with clomiphene-resistant polycystic ovary syndrome. PubMed, SCOPUS and CENTRAL databases were searched until April 2014 with the key words: PCOS, polycystic ovary syndrome, metformin, clomiphene citrate, ovulation induction and pregnancy. The search was limited to articles conducted with humans and published in English. The PRISMA statement was followed. Twelve randomized controlled trials (n = 1411 women) were included. Ovulation and clinical pregnancy rates per woman randomized. Compared with gonadotrophins, the metformin+clomiphene combination resulted in significantly fewer ovulations (odds ratio 0.25; 95% confidence interval 0.15-0.41; p < 0.00001, 3 trials, I(2) = 85%, n = 323) and pregnancies (odds ratio 0.45; 95% confidence interval 0.27-0.75; p = 0.002, 3 trials, I(2) = 0%, n = 323). No significant differences were found when metformin+clomiphene was compared with laparoscopic ovarian diathermy (odds ratio 0.88; 95% confidence interval 0.53-1.47; p = 0.62, 1 trial, n = 282; odds ratio 0.96; 95% confidence interval 0.60-1.54; p = 0.88, 2 trials, I(2) = 0%, n = 332, for ovulation and pregnancy rates, respectively). Likewise, no differences were observed in comparison with aromatase inhibitors (odds ratio 0.88; 95% confidence interval 0.58-1.34; p = 0.55, 3 trials, I(2) = 3%, n = 409; odds ratio 0.85; 95% confidence interval 0.53-1.36; p = 0.50, 2 trials, n = 309, for ovulation and pregnancy rates, respectively). There is evidence for the superiority of gonadotrophins, but the metformin+clomiphene combination is mainly relevant for clomiphene-resistant polycystic ovary syndrome patients and, if not effective, a next step could be gonadotrophins. More attempts with metformin+clomiphene are only relevant

To evaluate the relevance of body mass index (BMI), luteinizing hormone (LH), follicle-stimulating hormone (FSH) and LH/FSH ratio with clinical symptoms in polycystic ovary syndrome (PCOS) women. We reviewed the medical records of all women visited in the PCOS Clinic of Babol (Iran) from 2008 to 2012. A retrospective cross-sectional study was conducted on 175 PCOS women; aged 18-38 years diagnosed based on the Rotterdam criteria. Among the PCOs women, the prevalence of oligomenorrhea, acne, and hirsutism were found to be 92.0%, 31.4%, and 78.9%, respectively. Positive finding of polycystic ovaries was observed in 89.1% of PCOS women with by using sonography. A total of 69.2% overweight/obesity patients had polycystic ovary morphology on ultrasound image. Compared with non- overweight/obesity, the adjusted OR of PCOS women for sonographic view of polycystic ovaries was 4.33 (95% CI, 1.42-13.15, p=0.001), Nevertheless, the adjusted odds ratio (OR) showed no significant associations between LH, FSH, and LH/FSH ratio with clinical symptoms in these women. The findings of this study indicated that the overweight/obese women with PCOS are at an increased risk for sonographic view of polycystic ovaries. Therefore, it is suggested that successful weight loss is the most effective method of restoring ovulation, menstruation that should be used as major advice in obese PCOS patients.

Ms R, a 27-year-old woman with polycystic ovary syndrome (PCOS) diagnosed after irregular menses, hirsutism, and polycystic ovaries, is concerned about weight gain despite regular exercise and watching her diet. Prescribed oral contraceptives to regulate her menses and help reduce her androgen levels, she wants to know the alternatives for treatment of PCOS. The varying definitions of PCOS and its heterogeneity confound the interpretation of studies on PCOS. Specific diagnostic criteria have been established based on expert opinion but have not been validated. Several commonly performed laboratory tests are generally unhelpful and the pathophysiology is poorly understood. Treatment options for Ms R, including those that may affect her weight gain, are reviewed and implications for future fertility are discussed.

The effect of pharmaceutical intervention on lipid profile in polycystic ovary syndrome.

The polycystic ovary syndrome (PCOS), a prevalent endocrinopathy of women, has been associated with a clustering of adverse metabolic features, which co-exist with reproductive dysfunction. Lipid abnormalities are very common in lean as well as obese women with PCOS and should be cautiously considered in the therapeutic management of the syndrome. Clinicians should also critically assess the lipidemic effect of pharmaceutical intervention, primarily aimed at hyperandrogenism, anovulation or insulin resistance. Because dyslipidemia may contribute to long-term cardiometabolic and reproductive sequelae in PCOS, it should be considered as an additional therapeutic target when these patients are assigned to appropriate pharmaceutical treatment.

Women with polycystic ovary syndrome (PCOS) frequently exhibit central obesity, glucose intolerance, atherogenic dyslipidaemia and hypertension which are characteristic features of the metabolic syndrome (MetS). A total of 295 premenopausal Chinese women with PCOS diagnosed by the Rotterdam criteria (mean age: 30.2 +/- 6.4 years) and 98 control subjects without PCOS were evaluated for prevalence of MetS and cardiovascular risk factors, including dyslipidaemia and dysglycaemia. Using the 2005 modified Adult Treatment Panel III criteria, MetS (presence of three or more risk factors) was found in 24.9% of PCOS women compared to 3.1% of controls. The prevalence of MetS in PCOS women increased from 16.7% at under 30 years of age to 53.3% at over 40 years. MetS was also more prevalent in overweight and obese (41.3%) than normal-weight PCOS women (0.9%). However, multivariate regression analysis showed that women with PCOS had a 5-fold increase in risk of MetS (odds ratio 4.90; 95% confidence interval: 1.35-17.84) compared with women without PCOS even after controlling for age and BMI, suggesting PCOS alone is an independent risk factor for MetS. There is high prevalence of MetS in Hong Kong Chinese women with PCOS despite their relatively young age. Recognition of these cardiometabolic risk factors requires a high level of awareness in conjunction with early and regular screening.

This study was undertaken to study the effects of melatonin on metabolic and reproductive aspects of polycystic ovary syndrome (PCOS) in rats. PCOS was induced by daily subcutaneous administration of testosterone (20 mg/kg) to 21-day-old female rats for 35 days. Rats were given metformin (500 mg/kg), melatonin (1 mg/kg) or melatonin (2 mg/kg) along with testosterone. One group served as vehicle control. On the 36th day, the animals were euthanised, and anthropometrical, biochemical (glucose, insulin, lipids, testosterone, C reactive protein (CRP)), oral glucose tolerance test, and histopathological evaluation of ovaries, uterus and intraabdominal fat (IAF), were carried out. Daily colpocytological examination was carried out from 14(th) day of study until termination. Both the doses of melatonin significantly reduced body weight, body mass index, IAF, insulin and CRP. A favourable lipid profile, normal glucose tolerance and a decrease in the percentage of estrus smears were observed. Histopathological examination of ovary, uterus and IAF revealed a decrease in the number of cystic follicles, decrease in neoplastic endometrial glands, and decrease in adipocyte hypertrophy, respectively. The effects observed with melatonin were comparable to that with metformin. The study provides evidence of the potential beneficial effects of melatonin in PCOS. © 2014 Royal Pharmaceutical Society.

Polycystic ovary syndrome (PCOS) is the most common endocrine disease in women of reproductive age and is estimated to affect 5-10 % of the population. Women with PCOS have a clustering of cardiovascular risk factors, such as obesity, dyslipidemia, impaired glucose tolerance and hypertension. Homocysteine has been recognized recently as a risk factor for cardiovascular diseases. Preliminary investigations suggest that high sensitivity C-reactive protein, homocysteine and adiponectin are abnormal in women with PCOS. The possible determinants of elevated homocysteine concentration are still debated among authors who found significant correlations between homocysteine and insulin resistance or hyperandrogenism. The purpose of this study is to evaluate homocysteine levels in the PCOS population compared with controls. Study group comprised of 142 women with PCOS and 65 healthy non-PCOS controls. Body mass index (BMI), Waist circumference and serum homocysteine were measured in PCOS subjects and age matched controls. Statastical Analysis: All values are expressed as mean α SD. The results obtained are analysed statistically using the unpaired student t-test to evaluate the significance of differences between the mean values. The mean BMI, Waist circumference and serum homocysteine values are significantly increased in PCOS subjects when compared with non PCOS controls. The present study has demonstrated increase in mean serum homocysteine concentrations in women with PCOS.

Polycystic ovary syndrome (PCOS) is an under-recognized, common, and complex endocrinopathy. The name PCOS is a misnomer, and there have been calls for a change to reflect the broader clinical syndrome. The aim of the study was to determine perceptions held by women and primary health care physicians around key clinical features of PCOS and attitudes toward current and alternative names for the syndrome. We conducted a cross-sectional study utilizing a devised questionnaire. Participants were recruited throughout Australia via professional associations, women's health organizations, and a PCOS support group. Fifty-seven women with PCOS and 105 primary care physicians participated in the study. Perceptions of key clinical PCOS features and attitudes toward current and alternative syndrome names were investigated. Irregular periods were identified as a key clinical feature of PCOS by 86% of the women with PCOS and 90% of the primary care physicians. In both groups, 60% also identified hormone imbalance as a key feature. Among women with PCOS, 47% incorrectly identified ovarian cysts as key, 48% felt the current name is confusing, and 51% supported a change. Most primary care physicians agreed that the name is confusing (74%) and needs changing (81%); however, opinions on specific alternative names were divided. The name "polycystic ovary syndrome" is perceived as confusing, and there is general support for a change to reflect the broader clinical syndrome. Engagement of primary health care physicians and consumers is strongly recommended to ensure that an alternative name enhances understanding and recognition of the syndrome and its complex features.

Objective To compare the effectiveness of an electrocautery strategy with ovulation induction using recombinant follicle stimulating hormone in patients with polycystic ovary syndrome. Design Randomised controlled trial. Setting Secondary and tertiary hospitals in the Netherlands. Participants 168 patients with clomiphene citrate resistant polycystic ovary syndrome: 83 were allocated electrocautery and 85 were allocated recombinant follicle stimulating hormone. Intervention Laparoscopic electrocautery of the ovaries followed by clomiphene citrate and recombinant follicle stimulating hormone if anovulation persisted, or induction of ovulation with recombinant follicle stimulating hormone. Main outcome measure Ongoing pregnancy within 12 months. Results. The cumulative rate of ongoing pregnancy after recombinant follicle stimulating hormone was 67%. With only electrocautery it was 34%, which increased to 49% after clomiphene citrate was given. Subsequent recombinant follicle stimulating hormone increased the rate to 67% at 12 months (rate ratio 1.01, 95% confidence interval 0.81 to 1.24). No complications occurred from electrocautery with or without clomiphene citrate. Patients allocated to electrocautery had a significantly lower risk of multiple pregnancy (0.11, 0.01 to 0.86). Conclusion The ongoing pregnancy rate from ovulation induction with laparoscopic electrocautery followed by clomiphene citrate and recombinant follicle stimulating hormone if anovulation persisted, or recombinant follicle stimulating hormone, seems equivalent to ovulation induction with recombinant follicle stimulating hormone, but the former procedure carries a lower risk of multiple pregnancy.

Objective Polycystic ovary syndrome (PCOS) is characterized by phenotypic heterogeneity and has a wide variety of consequences. Approximately half of women with PCOS are overweight or obese, and their obesity may be a contributing factor to PCOS pathogenesis through different mechanisms. The aim of this study was to evaluate if PCOS alone affects the patients’ quality of life and to what extent obesity contributes to worsen this disease. Design To evaluate the impact of PCOS on health-related quality-of-life (HRQoL), 100 Mediterranean women with PCOS (group A), 50 with a body mass index (BMI) >25 kg/m2 (group A1) and 50 with BMI <25 kg/m2 (group A2), were recruited. They were evaluated with a specific combination of standardized psychometric questionnaires: the Symptom Checklist-90 Revised, the 36-Item Short-Form Health Survey, and the Polycystic Ovary Syndrome Questionnaire. The patients were compared with a normal-weight healthy control group of 40 subjects (group B). Another control group of 40 obese healthy women (group C) was used to make a comparison with PCOS obese patients (A1). Results Our results showed a considerable worsening of HRQoL in PCOS patients (A) compared with controls (B). In addition, patients with PCOS and BMI >25 (A1) showed a significant and more marked reduction in scores, suggesting a lower quality of life, compared with controls (B) and with normal-weight PCOS patients (A2). Conclusion PCOS is a complex disease that alone determines a deterioration of HRQoL. The innovative use of these psychometric questionnaires in this study, in particular the PCOS questionnaire, has highlighted that obesity has a negative effect on HRQoL. It follows that a weight decrease is associated to phenotypic spectrum improvement and relative decrement in psychological distress. PMID:28280314

Does unilateral laparoscopic diathermy adjusted to ovarian volume increase the chances of ovulation in women with polycystic ovary syndrome?

Does unilateral volume-adjusted laparoscopic diathermy increase the chances of ovulation in women with polycystic ovary syndrome (PCOS)? Although unilateral laparoscopic ovarian drilling (ULOD) using adjusted thermal doses was more efficient than bilateral laparoscopic ovarian drilling (BLOD) using fixed doses, the chances of ovulation were improved in patients irrespective of the technique used. The adjustment of the thermal dose to ovarian volume in BLOD increases ovulation and pregnancy rates compared with fixed-dose treatment, but BLOD causes the formation of adhesions, particularly on the left ovary, and increases the risk of damage to ovarian tissue. In contrast, ULOD with a fixed thermal dose minimizes the risk of ovarian tissue damage, and can increase the activity in both right and left ovaries, although this varies in humans and in other species. This prospective, longitudinal, study, between September 2009 and January 2013, included 96 infertile women with PCOS who were unresponsive to clomiphene citrate treatment and had underwent either ULOD or BLOD. After surgery, the groups were followed up for 6 months to assess ovulatory response. Patients were assigned to two groups; one group underwent laparoscopic ovarian drilling of the right ovary alone, while both ovaries were treated in the second group. The ULOD group (n = 49) received thermal doses adjusted to the volume of the right ovary (60 J/cm³). The BLOD group (n = 47) received fixed doses of 600 J per ovary, regardless of its volume. The two treatment groups were matched by the number of participants, age and baseline parameters. The ovulation rate during the first menstrual cycle after LOD was significantly higher in the ULOD group than in the BLOD group [73 versus 49%; absolute risk reduction (ARR), -0.25; 95% confidence interval (CI), -0.44 to -0.03; P = 0.014]. Treatment with ULOD on the right ovary significantly increased the chances of ovulation in patients with a larger right ovary compared

The frequency of polycystic ovary syndrome (PCOS) and the consequent fertility disorders cause many difficulties in the management of the assisted reproductive technics. Some studies are focused on different additional treatments, stimulation protocols or techniques that could optimize the in vitro fertilization cycles. The quality of the oocytes and embryos of these patients is also an outstanding issue. They remain difficult to actually evaluate during management, and none of the few published studies on this subject demonstrated any inferiority, compared to control patients. However, many differences have been highlighted, studying intra- and extra-ovarian factors. The advent of new genetic techniques could allow a better understanding of the pathophysiological mechanisms of the syndrome, as well as refining the evaluation of oocytes and embryos, in order to better predict the results of in vitro fertilization attempts. Pregnancy and birth rates, however, appear to be comparable to those of the general population. Copyright © 2017 Elsevier Masson SAS. All rights reserved.

Polycystic ovary syndrome (PCOS), an inflammatory, systemic, lifestyle endocrinopathy.

Patel, Seema

2018-04-17

Polycystic ovary syndrome (PCOS) is an endocrine disorder, afflicting females of reproductive age. This syndrome leads to infertility, insulin resistance, obesity, and cardiovascular problems, including a litany of other health issues. PCOS is a polygenic, polyfactorial, systemic, inflammatory, dysregulated steroid state, autoimmune disease, manifesting largely due to lifestyle errors. The advent of biochemical tests and ultrasound scanning has enabled the detection of PCOS in the affected females. Subsequently, a huge amount of insight on PCOS has been garnered in recent times. Interventions like oral contraceptive pills, metformin, and hormone therapy have been developed to bypass or reverse the ill effects of PCOS. However, lifestyle correction to prevent aberrant immune activation and to minimize the exposure to inflammatory agents, appears to be the sustainable therapy of PCOS. This holistic review with multiple hypotheses might facilitate to devise better PCOS management approaches. Copyright © 2018 Elsevier Ltd. All rights reserved.

Androgen excess fetal programming of female reproduction: a developmental aetiology for polycystic ovary syndrome?

PubMed

Abbott, D H; Barnett, D K; Bruns, C M; Dumesic, D A

2005-01-01

The aetiology of polycystic ovary syndrome (PCOS) remains unknown. This familial syndrome is prevalent among reproductive-aged women and its inheritance indicates a dominant regulatory gene with incomplete penetrance. However, promising candidate genes have proven unreliable as markers for the PCOS phenotype. This lack of genetic linkage may represent both extreme heterogeneity of PCOS and difficulty in establishing a universally accepted PCOS diagnosis. Nevertheless, hyperandrogenism is one of the most consistently expressed PCOS traits. Animal models that mimic fetal androgen excess may thus provide unique insight into the origins of the PCOS syndrome. Many female mammals exposed to androgen excess in utero or during early post-natal life typically show masculinized and defeminized behaviour, ovulatory dysfunction and virilized genitalia, although behavioural and ovulatory dysfunction can coexist without virilized genitalia based upon the timing of androgen excess. One animal model shows particular relevance to PCOS: the prenatally androgenized female rhesus monkey. Females exposed to androgen excess early in gestation exhibit hyperandrogenism, oligomenorrhoea and enlarged, polyfollicular ovaries, in addition to LH hypersecretion, impaired embryo development, insulin resistance accompanying abdominal obesity, impaired insulin response to glucose and hyperlipidaemia. Female monkeys exposed to androgen excess late in gestation mimic these programmed changes, except for LH and insulin secretion defects. In utero androgen excess may thus variably perturb multiple organ system programming and thereby provide a single, fetal origin for a heterogeneous adult syndrome.

Purpose Polycystic ovary syndrome (PCOS) is characterized by hyperandrogenic anovulation in women of reproductive age. We investigated the metabolic effects of lean and overweight adolescents with PCOS. Methods Anthropometric measurements and biochemical parameters were evaluated in 49 adolescents with PCOS and 40 age- and body mass index (BMI)-matched controls. We further divided both PCOS and control groups into those having BMI within the normal range of less than 85th percentile and those being overweight and obese with a BMI greater than 85th percentile. Results Hemoglobin, gamma-glutamyl transferase (r-GT), total cholesterol, low-density lipoprotein-cholesterol and 2-hour postglucose load plasma insulin levels were significantly elevated in the lean PCOS group than in the lean control group. In the overweight/obese PCOS group, hemoglobin and r-GT levels were significantly elevated than in the overweight/obese control group. In the normal weight group, none of the subjects had metabolic syndrome according to the Adult Treatment Panel III criteria, but the incidence of metabolic syndrome in the overweight/obese PCOS group was 8.3% and that in the overweight/obese control group was 6.7%. Conclusion PCOS in adolescents causes metabolic abnormalities, underscoring the importance of early diagnosis of PCOS in oligomenorrheic adolescents. PMID:26512349

Iron metabolism and the polycystic ovary syndrome.

PubMed

Escobar-Morreale, Héctor F

2012-10-01

The polycystic ovary syndrome (PCOS) is associated with insulin resistance and abnormal glucose tolerance. Iron overload may lead also to insulin resistance and diabetes. Serum ferritin levels are increased in PCOS, especially when glucose tolerance is abnormal, suggesting mild iron overload. Factors contributing to potential iron overload in PCOS include the iron sparing effect of chronic menstrual dysfunction, insulin resistance, and a decrease in hepcidin leading to increased iron absorption. Enhancement of erythropoiesis by androgen excess is unlikely, because soluble transferrin receptor levels are not increased in PCOS. Future venues of research should address the long-term effects of PCOS treatment on iron overload and, conversely, the possible effects of iron lowering strategies on the glucose tolerance of patients with PCOS.

Objective To compare the effectiveness of clomifene citrate plus metformin and clomifene citrate plus placebo in women with newly diagnosed polycystic ovary syndrome. Design Randomised clinical trial. Setting Multicentre trial in 20 Dutch hospitals. Participants 228 women with polycystic ovary syndrome. Interventions Clomifene citrate plus metformin or clomifene citrate plus placebo. Main outcome measure The primary outcome measure was ovulation. Secondary outcome measures were ongoing pregnancy, spontaneous abortion, and clomifene resistance. Results 111 women were allocated to clomifene citrate plus metformin (metformin group) and 114 women were allocated to clomifene citrate plus placebo (placebo group). The ovulation rate in the metformin group was 64% compared with 72% in the placebo group, a non-significant difference (risk difference - 8%, 95% confidence interval - 20% to 4%). There were no significant differences in either rate of ongoing pregnancy (40% v 46%; - 6%, - 20% to 7%) or rate of spontaneous abortion (12% v 11%; 1%, - 7% to 10%). A significantly larger proportion of women in the metformin group discontinued treatment because of side effects (16% v 5%; 11%, 5% to 16%). Conclusion Metformin is not an effective addition to clomifene citrate as the primary method of inducing ovulation in women with polycystic ovary syndrome.

Polycystic ovary syndrome (PCOS) is the most common cause of anovulatory infertility. There are multiple ways to induce ovulation in PCOS patients, which will eventually provide a successful live birth. Each of these treatments varies in aggressiveness and effectiveness. Ranging from lifestyle modifications, through insulin-sensitizing agents, selective estrogen receptor modulators, aromatase inhibitors, gonadotropins, to laparoscopic ovarian drilling and assisted reproductive techniques, each method achieves ovulation induction through different mechanisms of action. This review provides a description and specific characteristics of the different methods used for ovulation induction which can help to design a personalized approach to each PCOS patient, and a general stepwise approach to ovulation induction in these patients.

Complications and challenges associated with polycystic ovary syndrome: current perspectives.

Palomba, Stefano; Santagni, Susanna; Falbo, Angela; La Sala, Giovanni Battista

2015-01-01

Polycystic ovary syndrome (PCOS) represents the most common endocrine dysfunction in fertile women and it is considered a heterogeneous and multifaceted disorder, with multiple reproductive and metabolic phenotypes which differently affect the early- and long-term syndrome's risks. Women with PCOS present an adverse reproductive profile, including a high risk of pregnancy-induced hypertension, preeclampsia, and gestational diabetes mellitus. Patients with PCOS present not only a higher prevalence of classic cardiovascular risk factors, such as hypertension, dyslipidemia, and type-2 diabetes mellitus, but also of nonclassic cardiovascular risk factors, including mood disorders, such as depression and anxiety. Moreover, at the moment, clinical data on cardiovascular morbidity and mortality in women with PCOS are controversial. Finally, women with PCOS show an increased risk of endometrial cancer compared to non-PCOS healthy women, particularly during premenopausal period. Currently, we are unable to clarify if the increased PCOS early- and long-term risks are totally due to PCOS per se or mostly due to obesity, in particular visceral obesity, that characterized the majority of PCOS patients. In any case, the main endocrine and gynecological scientific societies agree to consider women with PCOS at increased risk of obstetric, cardiometabolic, oncology, and psychological complications throughout life, and it is recommended that these women be accurately assessed with periodic follow-up.

Polycystic ovary syndrome (PCOS) patients, frequently develop metabolic complications, such as insulin resistance (IR), impaired carbohydrate metabolism, dyslipidemia, obesity. Among the new markers responsible for metabolic disorders, preptin seems to be of great significance. One hundred and thirty-four women aged 17-45 were enrolled. PCOS was diagnosed in 73 women on the basis of ESHRE-ASRM criteria. Non-PCOS group consisted of 61 women with regular menstruation matched for nutritional status. All women underwent anamnesis, physical examination, anthropometric measurements, the abdominal ultrasound examination, and dual energy X-ray absorptiometry (DXA). Serum adropin levels were determined by ELISA. Biochemical and hormonal (testosterone, androstenedione, LH, FSH, estradiol) measurements were also performed. Insulin resistance indices (HOMA, QUICKI, Matsuda) and free androgen index (FAI) were calculated with the test results according to the standard formula. For all comparisons, statistical significance was defined by p ≤ .05. Serum preptin levels were significantly higher in the PCOS group. No significant correlations between preptin level and metabolic and hormonal markers were observed. The logistic regression analysis demonstrated that serum preptin level was an independent factor differentiating the two groups. Serum preptin levels were significantly higher in women with PCOS compared with controls. This peptide might be an independent predictor of PCOS in the future.

Polycystic ovary syndrome (PCOS) is a common condition in women at reproductive age associated with reproductive and metabolic dysfunction. Proposed diagnosed criteria for PCOS include two out of three features: androgen excess, menstrual irregularity, and polycystic ovary appearance on ultrasound (PCO), after other causes of hyperandrogenism and dysovulation are excluded. Based on these diagnostic criteria, the most common phenotypes are the "classic PCOS"--hyperandrogenism and oligomenorrhea, with or without PCO; the "ovulatory phenotype"--hyperandrogenism and PCO in ovulatory women; and the "non-hyperandrogenic phenotype", in which there is oligomenorrhea and PCO, without overt hyperandrogenism. The presence of obesity may exacerbate the metabolic and reproductive disorders associated with the syndrome. In addition, PCOS women present higher risk for type 2 diabetes and higher prevalence of cardiovascular risk factors that seems to be associated with the classic phenotype. The main interventions to minimize cardiovascular and metabolic risks in PCOS are lifestyle changes, pharmacological therapy, and bariatric surgery. Treatment with metformin has been shown to improve insulin sensitivity, lowering blood glucose and androgen levels. These effects are more potent when combined with lifestyle interventions. In conclusion, besides reproductive abnormalities, PCOS has been associated to metabolic comorbidities, most of them linked to obesity. Confounders, such as the lack of standard diagnostic criteria, heterogeneity of the clinical presentation, and presence of obesity, make management of PCOS difficult. Therefore, the approach to metabolic abnormalities should be tailored to the risks and treatment goals of each individual woman.

[Etiopathogenetic and clinical notes on the syndrome of the micropolycystic hyperandrogenic ovary and matrimonial sterility].

The nosological, clinical, aetiopathogenetic and therapeutic aspects of hyperandrogenic micropolycystic ovary are examined with particular reference to matrimonial sterility. There is not doubt about the existence of a syndrome substantially characterized, clinically, by menstrual trouble, inability to procreate, more or less evident signs of hyperandrogenism and a tendency to obesity and, morphologically, by ovarian micropolycystic alterations of typical pathognomonic aspect: the marked production of androgens on the part of the female gonad possibly accompanied by peripheral alterations interfering with their metabolism. The syndrome is not too frequent and, in personal experience, occurs in less than 1% of the series. The main therapeutic approach remains cuneiform resection of the ovary. Still in personal experience, 21.2% of cases treated led to pregnancy but not more than eight-ten months after operation. The effect would therefore appear to be transitory and the operation is decisively rejected where unmarried women are involved.

Polycystic ovary syndrome: definition, aetiology, diagnosis and treatment.

Polycystic ovary syndrome (PCOS) is one of the most common endocrine and metabolic disorders in premenopausal women. Heterogeneous by nature, PCOS is defined by a combination of signs and symptoms of androgen excess and ovarian dysfunction in the absence of other specific diagnoses. The aetiology of this syndrome remains largely unknown, but mounting evidence suggests that PCOS might be a complex multigenic disorder with strong epigenetic and environmental influences, including diet and lifestyle factors. PCOS is frequently associated with abdominal adiposity, insulin resistance, obesity, metabolic disorders and cardiovascular risk factors. The diagnosis and treatment of PCOS are not complicated, requiring only the judicious application of a few well-standardized diagnostic methods and appropriate therapeutic approaches addressing hyperandrogenism, the consequences of ovarian dysfunction and the associated metabolic disorders. This article aims to provide a balanced review of the latest advances and current limitations in our knowledge about PCOS while also providing a few clear and simple principles, based on current evidence-based clinical guidelines, for the proper diagnosis and long-term clinical management of women with PCOS.

Polycystic Ovary Syndrome: Effect and Mechanisms of Acupuncture for Ovulation Induction

Polycystic ovary syndrome (PCOS), the most common endocrine disorder among women of reproductive age, is characterized by the coexistence of hyperandrogenism, ovulatory dysfunction, and polycystic ovaries (PCO). PCOS also represents the largest part of female oligoovulatory infertility, and the management of ovulatory and menstrual dysfunction, comprises a third of the high costs of PCOS treatment. Current pharmacological and surgical treatments for reproductive symptoms are effective, however, associated with negative side effects, such as cardiovascular complications and multiple pregnancies. For menstrual irregularities and ovulation induction in women with PCOS, acupuncture has indicated beneficial effects. This review will focus on the results from randomized controlled acupuncture trials for regulation of menstrual dysfunction and for inducing ovulation in women with PCOS although there are uncontrolled trials with nonetheless interesting results. Animal experimental studies will be further discussed when they can provide a more mechanistic explanatory view. PMID:24073009

Polycystic ovary syndrome and weight management.

Polycystic ovary syndrome (PCOS) is a common condition in women of reproductive age, and has reproductive, metabolic and psychological implications. Weight gain and obesity worsen the features of PCOS, while weight loss improves the features of PCOS. While there are potential barriers to successful weight management in young women who do not suffer from PCOS, women with PCOS may experience additional barriers. Weight management strategies in younger women with or without PCOS should encompass both the prevention of excess weight gain and achieving and maintaining a reduced weight through multidisciplinary lifestyle management, comprising dietary, exercise and behavioral therapy, as well as attention to psychosocial stress and practical and physiological barriers to weight management. Further research is warranted in the examination of specific barriers to weight management in women with PCOS, as well as in the determination of optimal components of lifestyle weight management interventions in young women in order to facilitate long-term compliance.

Polycystic ovary syndrome is the most common endocrinological disorder affecting 4–12% of women and also the most controversial. Metformin was logically introduced to establish the extent to which hyperinsulinaemia influences the pathogenesis of the condition. Early studies were very encouraging. Randomized controlled studies and several metaanalyses have changed the picture and put the drug that was once heralded as magic in a much contracted place. More work is needed to establish its right place in particular with regards to the prevention of many gestational and long-term complications. PMID:23148156

The problem of Polycystic Ovary Syndrome (PCOS) is of a special importance due to its connection with not only medical but with psychosocial factors. PCOS is the most common endocrine cause of anovulatory infertility. It is a major factor for the metabolic syndrome, cardiovascular disease, type 2 diabetes mellitus (T2DM). Clinical symptoms of PCOS such as acne, hirsutism, obesity, alopecia represent psychological problem, especially for the adolescents. Many women who have PCOS have the onset of symptoms during adolescence. Early diagnosis and treatment of PCOS are important for preventing of the above mentioned long-term consequences associated with this condition. Adolescent patients often have diagnostic problems because the features of normal puberty are similar with symptoms of PCOS. This article reviews the diagnostic and differential diagnostic characteristics of PCOS in adolescents. In conclusion, consensus statement in adolescent patients is still awaiting. Our data suggest that it may be prudent to define adolescent PCOS according to the Carmina modified Rotterdam criteria. The increase rate of metabolic syndrome in adolescents with PCOS emphasize the importance of regular screening due to the high cardiometabolic disorders risk.

Pulsatile gonadotrophin releasing hormone for ovulation induction in subfertility associated with polycystic ovary syndrome.

PubMed

Bayram, N; van Wely, M; van der Veen, F

2004-01-01

In normal menstrual cycles, gonadotrophin releasing hormone (GnRH) secretion is pulsatile, with intervals of 60-120 minutes in the follicular phase. Treatment with pulsatile GnRH infusion by the intravenous or subcutaneous route using a portable pump has been used successfully in patients with hypogonadotrophic hypogonadism. Assuming that the results would be similar in women with polycystic ovary syndrome (PCOS), pulsatile GnRH has been used to induce ovulation in these women. Although ovulation and pregnancy have been achieved, the effectiveness of pulsatile GnRH in women with PCOS has not been clearly demonstrated. To assess the effectiveness of pulsatile GnRH administration in women with polycystic ovary syndrome (PCOS), in terms of ongoing pregnancy, ovulation, clinical pregnancy, ovarian hyperstimulation syndrome (OHSS), multiple pregnancy, miscarriage, and multifollicular growth. We searched the Cochrane Menstrual Disorders & Subfertility Group trials register (searched 13 August 2003), the Cochrane Central Register of Controlled Trials (CENTRAL) (Cochrane Library Issue 2, August 2001), MEDLINE (January 1966 to August 2003), EMBASE (January 1985 to August 2003) and reference lists of articles. We also contacted manufacturers and researchers in the field. All relevant published randomised clinical trials were selected for inclusion if treatment consisted of pulsatile GnRH administration versus another treatment for ovulation induction in subfertile women with PCOS. Relevant data were extracted independently by two reviewers (NB, MW). Validity was assessed in terms of method of randomisation, completeness of follow-up, presence or absence of crossover and co-intervention. All trials were screened and analysed for predetermined quality criteria. 2X2 tables were generated for all the relevant outcomes. Odds ratios were generated using the Peto method. Four randomised clinical trials involving 57 women were identified comparing four different treatments: Gn

Polycystic ovary syndrome (PCOS) is associated with insulin resistance and features in common with the metabolic syndrome (MetS)--factors shown to predict cardiovascular risk and type 2 diabetes. We investigated the prevalence and characteristics of the MetS in PCOS by three definitions-World Health Organization (WHO), National Cholesterol Education Program Adult Treatment Panel III (NCEP-ATP-III) and International Diabetes Federation (IDF)--and compared that with the background population. Cross-sectional study of 168 women with PCOS and 883 age-matched controls from the Australian Diabetes, Obesity and Lifestyle (AusDiab) study. Prevalence of the MetS in PCOS subjects was 33% by WHO, 37% by NCEP-ATP-III and 40% by IDF criteria, compared with 10% by NCEP-ATP-III and 13% by IDF in controls (P < 0.001). MetS by WHO criteria was not calculated in the AusDiab population. Age was an independent predictor of MetS in PCOS and controls. The prevalence of MetS was significantly higher among those with PCOS (P = 0.027) in obese women (BMI > 30 kg/m(2)), and higher but not significantly so in overweight (BMI 25-30 kg/m(2)) women (P = 0.052). Dehydroepiandrosterone sulphate was associated with a lower risk of the MetS--Odds ratio 0.86 (95% confidence interval, 0.77-0.97, P = 0.011). An approximate 4-fold increase in the prevalence of the MetS in women with PCOS compared with the general population, consistent with the proposed major role of insulin and obesity in the syndrome, implies greater risk of cardiometabolic disease in women with PCOS. However, this estimate is likely to vary according to PCOS definition, ethnicity and different aetiological pathways to PCOS.

Dyslipidemia is a feature of polycystic ovary syndrome (PCOS), but its pathogenesis remains controversial. We performed this study of mothers of women with PCOS to test the hypothesis that dyslipidemia is a heritable trait in families of women with PCOS and to investigate the impact of age on reproductive and metabolic phenotypes. Fasting blood was obtained in 215 non-Hispanic white mothers of women with PCOS and 62 control women. The prevalence of metabolic syndrome was compared with that in non-Hispanic white women of comparable age from the National Health and Nutrition Examination Survey III. Mothers had higher total (P < 0.001) and low-density lipoprotein (LDL) cholesterol levels (P = 0.007), whereas high-density lipoprotein and triglyceride levels did not differ compared with control women. The only predictors of LDL levels in mothers were their daughters’ LDL levels (r2 = 0.11, P < 0.001) and their own unbound testosterone levels (r2 = 0.04, P = 0.03). The prevalence of metabolic syndrome was increased in obese (body mass index ≥ 30 kg/m2) mothers compared with obese non-Hispanic white women from the National Health and Nutrition Examination Survey III (P = 0.04). Thirty-one percent of mothers reported a history of menstrual irregularity. These mothers had higher androgen levels, markers of insulin resistance, and LDL levels than mothers with regular menses. LDL levels are increased in mothers of women with PCOS, suggestive of a heritable trait. A history of menstrual irregularity identifies mothers with features of PCOS. Obese mothers have a very high prevalence of metabolic syndrome. These findings suggest that both the reproductive and metabolic abnormalities persist with age in PCOS. PMID:16632599

Androgens and polycystic ovary syndrome.

PubMed

Nisenblat, Vicki; Norman, Robert J

2009-06-01

Polycystic ovary syndrome (PCOS) is a common complex endocrine genetic disorder, which involves overproduction of androgens, leading to heterogeneous range of symptoms and associated with increased metabolic and cardiovascular morbidity. This review focuses on androgen biosynthesis, use, metabolism in PCOS and clinical consequences of hyperandrogenism. Controversial definition of the disorder and different phenotypic subgroups present a challenge for clinical and basic research. Further investigation of different phenotypes highlights the fact that PCOS probably represents a group of disorders with different etiologies. Prenatal androgen exposure and adolescent studies suggest early in life androgen excess as initiating factor of PCOS, but insufficient evidence available to confirm this hypothesis. Various intracellular signaling pathways implicated in PCOS steroidogenesis and in androgen action have been studied, however, PCOS pathogenesis remains obscure. Growing evidence links androgens with pathophysiology of PCOS and metabolic derangements. Despite intensive investigation, etiology and underlying mechanisms of PCOS remain unclear, warranting further investigation. Better understanding of molecular and genetic basis might lead to invention of novel therapeutic approaches. Long-term interventional studies that lower androgen levels in women with hyperandrogenism might protect against metabolic and cardiovascular comorbidities are needed.

A life course perspective on polycystic ovary syndrome

2014-01-01

Polycystic ovary syndrome (PCOS) is a major public health problem in the US. Worldwide, the public is largely unaware of the condition and health care providers do not seem to fully understand it. Research on PCOS has primarily focused on its etiology and clinical characteristics and less on the psychosocial aspects of human development associated with PCOS. This paper posits that a life course perspective provides a framework for further understanding the psychosocial experiences of women with PCOS and the contexts in which they live. The paper discusses how life course principles of human development, constraints on agency, interdependence of lives, time and place, and timing of events and experiences are relevant to the management of PCOS and prevention of its complications.

This study aimed to compare two methods of treatment of infertility with gonadotropin with laparoscopic ovarian electrocauterization in patients with clomiphene citrate-resistant polycystic ovary syndrome (PCOS). A number of 104 nulipara patients with polycystic ovary syndrome, who were resistant to clomiphene citrate were randomly assigned to two groups. One group received gonadotropin; after the bleeding withdrawal and from the third day of the cycle, the injection of human menopausal gonadotropin (HMG) was started with 10 mg medroxy progesterone. The patients were followed with serial trans-vaginal sonographies. When the diameter of follicles reached to 18 mm, human chorionic gonadotropin (HCG) was prescribed. The other group was treated with laparoscopic ovarian electrocauterization under general anesthesia. If after 3 cycles, the anovulation was established with progesterone measurement, the clomiphene citrate was prescribed. Gonadotropin was administered, if the lack of ovulation persisted. No significant difference was documented between the two groups in terms of the obesity indexes, duration of infertility, age, sonographic and laboratory findings. In the gonadotropin group, 37 cases (71%) of pregnancy occurred. The rate of pregnancy was the same in the other group consisting of 18 cases treated by electrocautery, 9 cases with cautery + clomiphene, and 10 cases with clomiphene + cautery + gonadotropin. In the group treated with gonadotropin, there were 1 triple and 4 twins pregnancies. In the group treated with ovarian electrocautery, one twin pregnancy was observed. In the group treated with gonadotropin, 2 cases of ovarian hyperstimulation syndrome, 1 case of ectopic pregnancy and 6 cases of miscarriage occurred; the corresponding figure in the ovarian electrocautery group consisted of 5 cases of miscarriage. Our findings suggest that ovarian electrocauterization is an appropriate method with good efficacy and low complication rate for infertility

Polycystic ovary syndrome (PCOS) is a heterogeneous and complex disorder that has both adverse reproductive and metabolic implications for affected women. However, there is generally poor understanding of its etiology. Varying expert-based diagnostic criteria utilize some combination of oligo-ovulation, hyperandrogenism, and the presence of polycystic ovaries. Criteria that require hyperandrogenism tend to identify a more severe reproductive and metabolic phenotype. The phenotype can vary by race and ethnicity, is difficult to define in the perimenarchal and perimenopausal period, and is exacerbated by obesity. The pathophysiology involves abnormal gonadotropin secretion from a reduced hypothalamic feedback response to circulating sex steroids, altered ovarian morphology and functional changes, and disordered insulin action in a variety of target tissues. PCOS clusters in families and both female and male relatives can show stigmata of the syndrome, including metabolic abnormalities. Genome-wide association studies have identified a number of candidate regions, although their role in contributing to PCOS is still largely unknown. PMID:26426951

Polycystic ovary syndrome (PCOS) is a heterogeneous syndrome characterized by oligo- or anovulation, clinical and/or biochemical signs of hyperandrogenemia and polycystic ovaries. Clinical expression is determined by both genetic and environmental factors. Dyslipidemia is very common in lean as well as in obese women with PCOS and should be considered in the therapeutic management of the syndrome. Additionally to dyslipidemia, other risk factors for cardiovascular disease strongly associated with PCOS include insulin resistance, impaired glucose tolerance and metabolic syndrome. Therefore, the ideal therapeutic approach for PCOS would be multi targeted treatment ameliorating not only ovarian dysfunction but also cardiometabolic aspects, including dyslipidemia. Recently, a new era of hypolipidemic agents like statins has been initiated with regard to PCOS. The spectrum of statins' targets has been expanded and in vitro and in vivo studies have explored the specific effect of statins on androgen production, insulin resistance and inflammatory markers in PCOS. Statins are potentially promising therapeutic agents targeting hormonal and metabolic disturbances in PCOS, though conclusive results are still pending. Since several hormonal and metabolic aberrations characterizing this multifaceted syndrome cluster and interact with each other, their effects on the lipid profile are interweaving and the therapeutic modalities targeting dyslipidemia appear to have a more broad beneficial effect.

Polycystic ovary syndrome (PCOS) is associated with psychological and metabolic disturbances. The aim of this study was to determine whether depression, anxiety and reduced health-related quality of life (HRQOL) are more common in women with PCOS and associated with metabolic risk. The study included 226 PCOS patients and 85 BMI-matched healthy control women. All participants completed standardized questionnaires assessing depression (Beck Depression Inventory), anxiety (State-Trait Anxiety Inventory) and both depression and anxiety (Hospital Anxiety and Depression Scale and General Health Questionnaire). Patients also completed a PCOS HRQOL questionnaire. Hirsutism scores, serum androgens and lipids were obtained. All subjects underwent a standard oral glucose tolerance test. 28.6% of PCOS women versus 4.7% of control women had clinical depression scores indicating an 8.1-fold increased risk of depression in PCOS (P < 0.001). Depression and anxiety scores were higher in PCOS women than controls (P < 0.01 for all subscales). Obese PCOS subjects had higher depression scores and rates than non-obese PCOS women (P < 0.05). Depression scores were significantly correlated with insulin resistance and lipid parameters and with the number of components comprising the metabolic syndrome. Menstrual and hirsutism problems were the most serious concerns followed by emotional problems on the HRQOL. Depression and anxiety are more common in patients with PCOS compared with healthy women. Depression in PCOS might be associated with obesity and metabolic abnormalities including insulin resistance and dyslipidemia.

Polycystic ovary syndrome represents 80% of anovulatory infertility cases. Treatment initially includes preconception guidelines, such as lifestyle changes (weight loss), folic acid therapy to prevent the risk of fetal neural tube defects and halting the consumption of tobacco and alcohol. The first-line pharmacological treatment for inducing ovulation consists of a clomiphene citrate treatment for timed intercourse. The second-line pharmacological treatment includes the administration of exogenous gonadotropins or laparoscopic ovarian surgery (ovarian drilling). Ovulation induction using clomiphene citrate or gonadotropins is effective with cumulative live birth rates of approximately 70%. Ovarian drilling should be performed when laparoscopy is indicated; this procedure is typically effective in approximately 50% of cases. Finally, a high-complexity reproduction treatment (in vitro fertilization or intracytoplasmic sperm injection) is the third-line treatment and is recommended when the previous interventions fail. This option is also the first choice in cases of bilateral tubal occlusion or semen alterations that impair the occurrence of natural pregnancy. Evidence for the routine use of metformin in infertility treatment of anovulatory women with polycystic ovary syndrome is not available. Aromatase inhibitors are promising and longer term studies are necessary to prove their safety. PMID:26602525

Polycystic ovary syndrome (PCOS) is associated with higher prevalence of cardiovascular risk factors but the relative prevalence of cardiovascular disease in women with PCOS has not previously been reported. We have compared cardiovascular mortality and morbidity in middle-aged women previously diagnosed with PCOS and age-matched control women. A retrospective cohort study of women diagnosed with PCOS in the United Kingdom before 1979. Seventy cohort members died before 31 March 1999. Morbidity data were collected from 319 women with PCOS and 1060 age-matched control women. Sixty-one women with PCOS and 63 control women attended a clinical examination. Data were collected from death certificates, general practitioners' records and questionnaires with measurement of cardiovascular risk factors in a subsample of questionnaire respondents. All-cause and cardiovascular mortality in the cohort were similar to women in the general population (standardized mortality ratios (95% CI): 93 (72-117) and 78 (45-124), respectively). Women with PCOS had higher levels of several cardiovascular risk factors: diabetes (P = 0.002) hypertension (P = 0.04), hypercholesterolaemia (P < 0.001), hypertriglyceridaemia (P = 0.02) and increased waist:hip ratio (P = 0.004). After adjustment for BMI, odds ratios (OR) were 2.2 (0.9-5. 2) for diabetes, 1.4 (0.9-2.0) for hypertension and 3.2 (1.7-6.0) for hypercholesterolaemia. A history of coronary heart disease (CHD) was not significantly more common in women with PCOS (crude OR (95%CI) 1.5 (0.7-2.9)) but the crude OR for cerebrovascular disease was 2.8 (1.1-7.1). At long-term follow-up, a history of nonfatal cerebrovascular disease and cardiovascular risk factors including diabetes are more prevalent among women with polycystic ovary syndrome. Morbidity and mortality from of coronary heart disease among women with polycystic ovary syndrome is not as high as previously predicted. This finding challenges our understanding of the aetiology of

Polycystic ovary syndrome (PCOS) is associated with cardiovascular risk but it is not clear if this is independent of obesity and insulin resistance. This study therefore investigates endothelial function and arterial stiffness in nonobese, noninsulin resistant women with PCOS. This is cross-sectional case-control study. A total of 19 young women with PCOS, with body mass index (BMI) <30 kg/m(2), and 19 healthy controls matched for age and BMI were included in the study. Endothelial function was assessed with flow mediated dilatation (FMD) of the brachial artery, while arterial stiffness was assessed with pulse wave velocity (PWV) and augmentation index (AI). There were no significant differences between PCOS and control subjects when assessing the following clinical and biochemical variables: blood pressure, homeostasis model assessment insulin-resistance index, lipids and oestradiol. Women with PCOS had higher free androgen index scores (5.14 ± 3.47 vs. 3.25 ± 1.42, P = 0.036). The PCOS subjects had significantly lower FMD of the brachial artery compared with the controls (6.5 ± 2.9%vs. 10.5 ± 4.0%, P < 0.01). There were no significant differences in markers of arterial stiffness (PWV 5.8 ± 1.1 vs. 6.0 ± 1.0, P = 0.58, AI 16.5 ± 10.2 vs. 20.3 ± 10.2, P = 0.25). Women with polycystic ovary syndrome who are young, nonobese, and have no biochemical evidence of insulin resistance, have abnormal vascular function, but normal arterial stiffness, when compared with age and weight matched control subjects. Whether this leads to a greater risk of cardiovascular disease requires further investigation. © 2009 Blackwell Publishing Ltd.

To evaluate the possible relationship between subclinical hypothyroidism (SCH) and metabolic syndrome (MS) and the response to clomiphene citrate (CC) stimulation in women with polycystic ovary syndrome (PCOS). One hundred and ninety-six women with PCOS were divided into two groups: (1) the SCH group with 92 patients; (2) the euthyroid (EU) group with 104 patients. Physical characteristics and metabolic parameters as well as the reaction to CC stimulating test were compared between these two groups. (1) In the SCH group, significantly higher body mass index, Ferriman-Gallwey score, serum triglyceride, insulin and glucose of oral glucose tolerance test, homeostatic model assessment-insulin resistance (HOMA-IR) and significantly lower serum high-density lipoprotein cholesterol was observed in comparison with those in the EU group (p < 0.05). (2) The prevalence of CC resistance (30.4%), IR (43.5%) and MS (34.8%) in the SCH group was significantly higher than that in the EU group (p < 0.05). SCH was found associated with IR, MS and CC resistance in women with PCOS. PCOS patients with SCH may have a poorer treatment response to ovulation induction with CC.

Polycystic Ovary Syndrome (PCOS) is a reproduction problem that causes irregular menstruation period. Insulin and androgen hormone have big roles for this problem. This syndrome should be detected shortly, since it is able to cause a more serious disease, such as cardiovascular, diabetes, and obesity. The detection of this syndrome is done by analyzing ovary morphology and hormone test. However, the more economical way of test is by identifying the ovary morphology using ultrasonography. To classify whether one ovary is normal or it has polycystic ovary (PCO) follicle, the analysis will be done manually by a gynecologist. This paper will design a system to detect PCO using Gabor Wavelet method for feature extraction and Elman Neural Network is used to classify PCO and non-PCO. Elman Neural Network is chosen because it contains context layer to recall the previous condition. This paper compared the accuracy and process time of each dataset, then also did testing on elman’s parameters, such as layer delay, hidden layer, and training function. Based on tests done in this paper, the most accurate number is 78.1% with 32 features.

High-fat diet exposure from pre-pubertal age induces polycystic ovary syndrome (PCOS) in rats.

Polycystic ovary syndrome (PCOS) is associated with hyperandrogenism, oligo-anovulation, polycystic ovaries and metabolic syndrome. Many researchers reported that PCOS often starts with menarche in adolescents. Presently available animal model focuses on ovarian but not metabolic features of PCOS. Therefore, we hypothesized that high-fat diet feeding to pre-pubertal female rats results in both reproductive and metabolic features of PCOS. Pre-pubertal female rats were divided into two groups: group I received normal pellet diet and group II received high-fat diet (HFD). In the letrozole study, adult female rats were divided into two groups: group I received 1% carboxy methyl cellulose and group II received 1 mg/kg letrozole orally. Oral glucose tolerance test, lipid profile, fasting glucose, insulin, estrus cycle, hormonal profile, ovary weight, luteinizing hormone (LH) receptor and follicle-stimulating hormone receptor expression were measured. Polycystic ovarian morphology was assessed through histopathological changes of ovary. Feeding of HFD gradually increase glucose intolerance and fasting insulin levels. Triglyceride level was higher in HFD study while total cholesterol level was higher in the letrozole study. Alteration in testosterone and estrogen levels was observed in both studies. LH receptor expression was upregulated only in HFD study. Histopathological changes like increase cystic follicle, diminished granulosa cell layer and thickened theca cell layer were observed in letrozole as well as HFD study. High-fat diet initiated at pre-puberty age in rats produces both metabolic disturbances and ovarian changes similar to that observed clinically in PCOS patients. Letrozole on the other hand induces change in ovarian structure and function. © 2018 Society for Reproduction and Fertility.

To study the therapeutic efficacy of Modified Zigui Decoction (MZD) in treatment of polycystic ovary syndrome of Gan-Shen yin deficiency syndrome. 66 polycystic ovary syndrome patients of Gan-Shen yin deficiency syndrome were randomly assigned to the MZD group (Group A) and the Westem medicine group (Group B), 33 patients in each. Patients in Group A orally took MZD, while those in Group B orally took Diane-35. Their menstrual cycle rate, basal body temperature (BBT), the ovarian size, the number of follicles, and changes of endocrine hormones were observed before treatment, the first menstrual cycle, and the sixth menstrual cycle after treatment. (1) The normal rate of one menstrual cycle after stopping taking medicine was 57.58% in Group A and 63.64% in Group B. There was no statistical difference between the two groups (P>0.05). The normal rate of six menstrual cycles after stopping taking medicine was 45. 45% in Group A and 21.21% in Group B. The former was superior to the latter, showing statistical difference (P<0.05). (2) The biphasic BBT rates of one menstrual cycle after stopping taking medicine were somewhat elevated in the two groups, better than before treatment respectively (P<0.01). But there was no statistical difference between the two groups (P>0.05). The biphasic BBT rate of six menstrual cycles after stopping taking medicine was 45.45% in Group A and 18.18% in Group B. The former was superior to the latter, showing statistical difference (P<0.05). (3) The bilateral ovarian volume of one menstrual cycle after stopping taking medicine was obviously reduced in both groups (P<0.01). The bilateral ovarian volume of six menstrual cycles after stopping taking medicine was still more reduced than before treatment in Group A (P<0.01), while it returned to the size of before treatment in Group B (P>0.05). (4) The number of follicles of one menstrual cycle after stopping taking medicine was obviously reduced in both groups (P<0.01). The number of follicles

The aim of this study was to investigate a proposed correlation between the incidentally discovered undescended ovaries and their confirmed diagnosis as a polycystic ovary disease (PCOD) for all cases included, and to evaluate the role of estimated insulin like factor 3 (INSL3) circulating level in the pathogenesis of both abnormal findings. The study group (A) comprised 35 women whose ovaries had been incidentally found to be undescended during the routine laparoscopy for infertility causes, and all had been diagnosed as PCOD. The control category included two subgroups; subgroup (B) included 35 women group, diagnosed as PCOD but with normally allocated ovaries in the true pelvis, and subgroup (C) included 35 healthy women with regular menses and no signs of hyperandrogenism. Correlations between the level of INSL3 and other PCOD relevant biochemical tests: [e.g. BMI, waist-to-hip ratio (WHR), LH, FSH, androstendione (A), total and free testosterone (T & Ft), DHEA-S, and SHBG] had been also investigated. INSL3 levels were significantly higher in PCOD groups (A) and (B) compared to the healthy fertile control subgroup (C) (80.5 ± 29.4, 65.11 ± 15.6, and 41.11 ± 10.2 pg/mL, respectively), and was highest in group (A). Moreover, we identified a strong correlation between INSL3 and androstenedione (r = 0.42, p = 0.0012), and free (r = 0.42, p = .0123) and total testosterone (r = 0.41, p = .004) in the PCOD (A) and (B) subgroup compared to the levels in subgroup (C). LH was significantly higher in all PCOD women in groups (A&B) (12. 3 ± 3.4, and 11.2 ± 1.4 mIU/L, respectively) compared to those in group (A) (5.7 ± 2.5 mIU/L), with a fair correlation with INSL3. However, there was no statistically significant correlation between INSL3 and FSH, DHEA-S, glucose, basal insulin concentration or HOMA-IR in all PCOD women. The strong positive correlation between INSL3, and high ovarian androgens levels in all PCOD women

Pulsatile luteinising hormone releasing hormone for ovulation induction in subfertility associated with polycystic ovary syndrome.

In normal menstrual cycles, gonadotrophin releasing hormone (GnRH) secretion is pulsatile, with intervals of 60-120 minutes in the follicular phase. Treatment with pulsatile GnRH infusion by the intra-venous or subcutaneous route using a portable pump has been used successfully in patients with hypogonadotrophic hypogonadism. Assuming that the results would be similar in polycystic ovary syndrome (PCOS), pulsatile GnRH has been used to induce ovulation in patients with PCOS. But, although ovulation and pregnancy has been achieved, the use of pulsatile GnRH in PCOS patients is controversial. To assess the effectiveness of pulsatile GnRH administration in women with clomiphene-resistant polycystic ovary syndrome (PCOS), in terms of ovulation induction, pregnancy, miscarriage, multiple pregnancy and ovarian hyperstimulation syndrome (OHSS). The search strategy of the Menstrual Disorders and Subfertility review group was used to identify all relevant trials. Please see Review Group details. All relevant published RCTs were selected. Non-randomised controlled trials were eligible for inclusion if treatment consisted of GnRH administration versus another treatment to induce ovulation in subfertile women with PCOS. A computerised MEDLINE and EMBASE search was used to identify randomised and non randomised controlled trials. The reference lists of all studies found were checked for relevant articles. One RCT (Bringer 1985a) and one abstract (Coelingh 1983) were identified this way. Relevant data were extracted independently by two reviewers (NB, MW). Validity was assessed in terms of method of randomization, completeness of follow-up, presence or absence of cross-over and co-intervention. All trials were screened and analysed for predetermined quality criteria. 2X2 tables were generated for all the relevant outcomes. Odds ratios were generated using the Peto modified Mantel-Haenszel technique. Three RCTs and one non-randomised comparative trial were identified comparing

Mediators of low-grade chronic inflammation in polycystic ovary syndrome (PCOS).

2013-01-01

Chronic low-grade subclinical inflammation has been increasingly recognized as an interposer in the endocrine, metabolic and reproductive disturbances that characterize the polycystic ovary syndrome (PCOS). Abdominal adiposity and obesity are often present in PCOS. Mounting evidence indicates that adipose tissue is involved in innate and adaptive immune responses. Continuous release of inflammatory mediators such as cytokines, acute phase proteins, and adipokines perpetuates the inflammatory condition associated with obesity in women with PCOS, possibly contributing to insulin resistance and other long-term cardiometabolic risk factors. Genetic variants in the genes encoding inflammation-related mediators underlie the development of PCOS and their interaction with environmental factors may contribute to the heterogeneous clinical phenotype of this syndrome. In the future, strategies ameliorating inflammation may prove useful for the management of PCOS and associated conditions.

OBJECTIVE To construct and validate a questionnaire for use in diagnosis of polycystic ovary syndrome (PCOS). DESIGN All participants completed a questionnaire, which asked clinical questions designed to assist in the diagnosis of PCOS, before their appointments with an endocrinologist. Following completion of the questionnaire, the endocrinologist (blinded to the answers) made or excluded a diagnosis of PCOS using clinical criteria and biochemical data as indicated. Questions were then evaluated for their power to predict PCOS, and a model was constructed using the most reliable items to establish a system to predict a diagnosis of PCOS. SETTING An outpatient reproductive endocrinology clinic in Calgary, Alta. PARTICIPANTS Adult women patients who had been referred to the clinic. Fifty patients with PCOS and 50 patients without PCOS were included in the study. MAIN OUTCOME MEASURES Demographic information, medical history, related diagnoses, menstrual history, and fertility history. RESULTS A history of infrequent menses, hirsutism, obesity, and acne were strongly predictive of a diagnosis of PCOS, whereas a history of failed pregnancy attempts was not useful. A history of nipple discharge outside of pregnancy strongly predicted no diagnosis of PCOS. We constructed a 4-item questionnaire for use in diagnosis of PCOS; the questionnaire yielded a sensitivity of 85% and a specificity of 85% on multivariate logistic regression and a sensitivity of 77% and a specificity of 94% using the 4-item questionnaire. Predictive accuracy was validated using a second sample of 117 patients, in addition to internal validation using bootstrap analysis. CONCLUSION We have constructed a simple clinical tool to help diagnose PCOS. This questionnaire can be easily incorporated into family physicians’ busy practices. PMID:17872783

The aim of study was to assess the relationship between zinc-α2-glycoprotein (ZAG) and androgen excess with insulin resistance in polycystic ovary syndrome (PCOS) women. 99 PCOS women and 100 healthy controls were recruited. Euglycemic-hyperinsulinemic clamp (EHC) was preformed to assess their insulin sensitivity. Circulating ZAG was determined with an ELISA kit. In healthy subjects, circulating ZAG levels exhibited a characteristic diurnal rhythm in humans, with a major nocturnal rise occurring between midnight and early morning. Circulating ZAG and M-value were much lower in PCOS women than in the controls. In all population, overweight/obese subjects had significantly lower circulating ZAG levels than lean individuals. Multiple linear regression analysis revealed that only M-value and the area under the curve for glucose were independently related factors to circulating ZAG in PCOS women. Multivariate logistic regression analysis showed that circulating ZAG was significantly associated with PCOS even after controlling for anthropometric variables, blood pressure, lipid profile and hormone levels. The PCOS women with high ZAG had fewer MetS, IGT and polycystic ovaries as compared with the low ZAG PCOS women. Taken together, circulating ZAG levels are reduced in women with PCOS and ZAG may be a cytokine associated with insulin resistance in PCOS women. PMID:27180914

Polycystic ovary syndrome (PCOS), a common female endocrinopathy, is a complex metabolic syndrome of enhanced weight gain. The goal of this pilot study was to evaluate metabolic differences between normal (n=10) and PCOS (n=10) women via breath carbon isotope ratio, urinary nitrogen and nuclear magnetic resonance (NMR)-determined serum metabolites. Breath carbon stable isotopes measured by cavity ring down spectroscopy (CRDS) indicated diminished (p<0.030) lipid use as a metabolic substrate during overnight fasting in PCOS compared to normal women. Accompanying urinary analyses showed a trending correlation (p<0.057) between overnight total nitrogen and circulating testosterone in PCOS women, alone. Serum analyzed by NMR spectroscopy following overnight, fast and at 2 h following an oral glucose tolerance test showed that a transient elevation in blood glucose levels decreased circulating levels of lipid, glucose and amino acid metabolic intermediates (acetone, 2-oxocaporate, 2-aminobutyrate, pyruvate, formate, and sarcosine) in PCOS women, whereas the 2 h glucose challenge led to increases in the same intermediates in normal women. These pilot data suggest that PCOS-related inflexibility in fasting-related switching between lipid and carbohydrate/protein utilization for carbon metabolism may contribute to enhanced weight gain.

Polycystic ovary syndrome (PCOS) is a heterogenous endocrine disorder with typical symptoms of oligomenorrhoea, hyperandrogenism, hirsutism, obesity, insulin resistance and increased risk of type 2 diabetes mellitus. Extensive evidence indicates that PCOS is a genetic disease and numerous biochemical pathways have been linked with its pathogenesis. A number of genes from these pathways have been investigated, which include those involved with steroid hormone biosynthesis and metabolism, action of gonadotropin and gonadal hormones, folliculogenesis, obesity and energy regulation, insulin secretion and action and many others. In this review, we summarize the historical and recent findings in genetic polymorphisms of PCOS from the relevant publications and outline some genetic polymorphisms that are potentially associated with the risk of PCOS. This information could uncover candidate genes associating with PCOS, which will be valuable for the development of novel diagnostic and treatment platforms for PCOS patients. © 2018 The authors.

Insulin sensitizers in adolescents with polycystic ovary syndrome.

LE, Trang N; Wickham, Edmond P; Nestler, John E

Polycystic ovary syndrome (PCOS) is the most common disorder of androgen excess in women of reproductive age. The diagnosis of PCOS can be more challenging in adolescents than in adult women given significant overlap between normal puberty and the signs of PCOS, including acne, menstrual irregularity, and polycystic ovarian morphology. Optimal treatments for adult women with PCOS vary depending on patient risk factors and reproductive goals, but mainly include hormonal contraception and insulin sensitizers. There is continued interest in targeting the intrinsic insulin resistance that contributes to metabolic and hormonal derangements associated with PCOS. The vast majority of published data on insulin sensitizing PCOS treatments are reported in adult women; these have included weight loss, metformin, thiazolidinediones, and the inositols. Furthermore, there is also a small but growing body of evidence in support of the use of insulin sensitizers in adolescents, with or without oral contraceptives. Discussion of the available treatments, including benefits, potential side effects, and incorporation of patient and family preferences is critical in developing a plan of care aimed at achieving patient-important improvements in PCOS signs and symptoms while addressing the longer-term cardiometabolic risks associated with the syndrome.

Mayer-Rokitansky-Küster-Hauser (MRKH) syndrome is a rare syndrome characterized by complete or partial agenesis of the uterus and vagina, due to a congenital defect of the Mullerian duct. Affected individuals have a 46,XX karyotype and a normal female phenotype. MRKH syndrome may be isolated (type I MRKH syndrome) or associated with renal, cardiac, and skeletal anomalies, short stature, and auditory defects. The latter is defined as type II MRKH syndrome or the Müllerian duct aplasia/hypoplasia, renal agenesis/ectopy, and cervicothoracic somite dysplasia (MURCS) association. The majority of patients with MRKH syndrome present with primary amenorrhea. We report a case of type II MRKH syndrome who has been referred by a pediatric surgeon for detection of gonadal function. During an inguinal hernia operation, the left ovary had been observed in the hernia sac. Clinical and radiological evaluation of the patient showed an absence of the uterus and left kidney, and cervical hemi vertebra. Based on these findings, the patient was diagnosed as having type II MRKH syndrome.

Long-term effects of laparoscopic electrocautery of the ovaries are unknown. To study the long-term effects of laparoscopic electrocautery of the ovaries and gonadotrophins, we followed women with clomiphene-resistant polycystic ovary syndrome (PCOS) randomly allocated to one of these treatments until 8-12 years after their initial treatment. Between February 1998 and October 2001 168 women with clomiphene citrate-resistant PCOS were included in a randomized controlled trial comparing an electrocautery strategy to a strategy starting with rFSH. In 2009 these women were contacted about their reproductive outcome and menstrual cycle regularity. Analysis was by intention-to-treat. We compared time to conception resulting in live birth, subsequent pregnancies, ectopic and multiple pregnancies, menopause, as well as minimal and maximal menstrual cycle length. After 8-12 years, the cumulative proportion of women with a first child was 86% in women who had been allocated to electrocautery versus 81% in women who had been allocated to immediate rFSH [relative ratio (RR): 1.1; 95% confidence interval (CI): 0.92-1.2]. Treatment with electrocautery resulted in a significantly lower need for stimulated cycles to reach a live birth; 53% after electrocautery versus 76% after rFSH (RR: 0.69; 95% CI: 0.55-0.88).The cumulative proportion of women with a second child was 61% after electrocautery versus 46% after immediate rFSH (RR: 1.4; 95% CI: 1.00-1.9). Overall, there were 7 twins out of 134 deliveries (5%) after electrocautery versus 10 twins out of 124 deliveries (8%) in the rFSH group (RR: 0.65; 95% CI: 0.25-1.6). Fifty-four per cent of the women allocated to electrocautery had a regular menstrual cycle 8-12 years after randomization versus 36% in those allocated to rFSH (RR: 1.5; 95% CI: 0.87-2.6). In women with clomiphene-resistant PCOS, laparoscopic electrocautery of the ovaries is as effective as ovulation induction with FSH treatment in terms of live births, but reduces

Whether or not acarbose benefits patients with polycystic ovary syndrome (PCOS) remains controversial. Therefore, we performed a meta-analysis to synthesize the literature regarding the therapeutic effects of acarbose on PCOS. A comprehensive literature search was performed using terms, such as polycystic ovary syndrome, ovary polycystic disease, PCOS, hyperandrogenemia, acarbose, alpha-glucosidase inhibitors, and randomized controlled trials (RCTs), in the following bibliographic databases: Medline; Embase; and Cochrane Controlled Trials Register. The identified reference lists were checked manually. 6 RCTs met the inclusion criteria. Based on the meta-analysis of 3 studies, acarbose was superior to placebo or no treatment in reducing serum levels of testosterone (Std MD = - 3.38, 95% CI:-5.97~-0.78, P = 0.01) and acarbose caused a significantly higher incidence of side effects, such as abdominal distention and diarrhea (OR = 23.78, 95% CI: 5.67~99.75, P < 0.0001). The changes in Ferriman-Gallwey score or body mass index (BMI) were not significant. Based on the meta-analysis of 2 studies, acarbose were superior to placebo or no treatment in reducing triglycerides (TG; WMD = -18.18, 95% CI:-36.30~-0.06, P = 0.05) and very low-density lipoprotein (VLDL) cholesterol (WMD = - 6.49, 95% CI:-9.14~-3.84, P < 0.00001), and increasing high-density lipoprotein (HDL) cholesterol (WMD = 5.14, 95% CI:1.73~8.55, P = 0.003). There were no significant differences between acarbose and metformin with respect to improvements in ovulation rate, menstrual patterns, or changes in serum levels of testosterone, adverse events, or BMI. Heterogeneities were detected during the meta-analysis. This is the first meta-analysis to evaluate the role that acarbose plays in the treatment of PCOS. The currently available data showed that acarbose can reduce testosterone, TG, and VLDL, and increase HDL. Acarbose caused a significantly higher incidence of gastrointestinal disturbance. Given the

Polycystic ovary syndrome (PCOS) is an ovulatory disorder that affects 6-10% of women of reproductive age. Serum AMH level may be an additional factor, or surrogate of PCOM, in the diagnostic criteria of PCOS. We evaluated the correlations between the serum AMH level and various endocrine and metabolic features in PCOS using the latest fully automated assay. Serum AMH level was compared between 114 PCOS patient (PCOS group) and 95 normal menstrual cycle women (Control group). Correlations between serum AMH level and various endocrine and metabolic factors were analysed in PCOS group. The serum AMH level was significantly higher in the PCOS group (8.35±8.19 ng/mL) than in the Control group (4.99±3.23 ng/mL). The serum AMH level was independently affected by age and the presence of PCOS on multiple regression analysis. Ovarian volume per ovary (OPVO) showed the strongest positive correlation (r=0.62) with the serum AMH level among related factors. On receiver operating characteristic (ROC) curve analysis, the cut-off value of AMH for the diagnosis of PCOS was 7.33 ng/mL, but this value did not have high efficacy (sensitivity 44.7%, specificity 76.8%). A cut-off value of 10 ng/mL had a high specificity of 92.6%, although the sensitivity was low (24.6%). The serum AMH level was elevated and reflected ovarian size in PCOS patients. The serum AMH level could be a surrogate for ultrasound findings of the ovaries in PCOS and might be useful for estimating ovarian findings without transvaginal ultrasound in the diagnosis of PCOS.

The present study was designed to evaluate the effects of metformin on metabolic and endocrine parameters in patients with polycystic ovary syndrome (PCOS). The study included 40 patients with PCOS. Patients were divided into 2 groups based on whether they will receive metformin (500 mg 3 times a day, n=20) or placebo (n=20) for 3 consecutive months. Serum concentrations of fasting blood glucose, insulin, HOMA-IR, INSL-3, visfatin, FSH, and LH were measured at baseline and after 3 months of therapy. The key endocrine and metabolic parameters significantly changed after metformin treatment. The systolic and diastolic blood pressures were significantly reduced in the metformin group after treatment compared to placebo (p<0.001). A significant reduction in the size of the right ovary was observed after metformin treatment (p=0.05), while no change was found in the size of left ovary (p>0.12). Moreover, a significant reduction was observed in the serum levels of FSH (p>0.01), LH (p>0.001), and visfatin (p>0.001) after metformin treatment. However, HOMA-IR (which is used to assess insulin resistance) failed to reach the statistical significance (p=0.20). We conclude that metformin treatment in females with PCOS showed significant improvement in systolic and diastolic blood pressures. In addition, an improvement in the hormonal profile in the form of reduction in LH, FSH, and visfatin levels was observed. Thus, therapeutic intervention with metformin could be of clinical importance in high-risk group of young females with PCOS. © Georg Thieme Verlag KG Stuttgart · New York.

Polycystic Ovary Syndrome(PCOS) is the most common endocrine disorders affected to female in their reproductive cycle. This has gained the attention from married couple which affected by infertility. One of the diagnostic criteria considereded by the doctor is analysing manually the ovary USG image to detect the number and size of ovary's follicle. This analysis may affect low varibilites, reproducibility, and efficiency. To overcome this problems. automatic scheme is suggested to detect the follicle on USG image in supporting PCOS diagnosis. The first scheme is determining the initial homogeneous region which will be segmented into real follicle form The next scheme is selecting the appropriate regions to follicle criteria. then measuring the segmented region attribute as the follicle. The measurement remains the number and size that aimed at categorizing the image into the PCOS or non-PCOS. The method used is region growing which includes region-based and seed-based. To measure the follicle diameter. there will be the different method including stereology and euclidean distance. The most optimum system plan to detect PCO is by using region growing and by using euclidean distance on quantification of follicle.

Polycystic ovary syndrome (PCOS) affects around 15% of Indigenous women who are also a group at high risk of cardiometabolic disease. To explore the impact of PCOS on metabolic syndrome in Indigenous women. A cross-sectional reproductive health questionnaire, biochemical and anthropometric assessments, of 109 Indigenous women (35 with PCOS and 74 without PCOS) aged 15-44 years in and around Darwin between 2003 and 2005. PCOS was defined using the National Institutes of Health criteria, and metabolic syndrome (MetS) using the National Cholesterol Education Programme Adult Treatment Programme III criteria. The outcome was prevalence of MetS by PCOS status; relationship of PCOS with MetS before and after adjustment for markers of obesity and insulin resistance. Women with PCOS had a significantly higher body mass index (BMI) (P = 0.0001) and MetS was more frequent in women with PCOS (51%) than those without PCOS (23%) (P = 0.003). The most frequent components of MetS in both groups were a high density lipoprotein cholesterol ≤1.29 mmol/L (80% PCOS, 55% non-PCOS) and a waist circumference >88 cm (77% PCOS, 41% non-PCOS); these were significantly more frequent in women with PCOS (P = 0.01). In logistic regression models, PCOS was significantly associated with MetS by itself but not after adjustment for BMI or sex hormone binding globulin. While MetS was more common in Indigenous women with PCOS, PCOS was not an independent predictor of MetS. This may be because obesity and insulin resistance are integral parts of PCOS and are the mechanisms through which PCOS exerts metabolic effects. © 2015 Royal Australasian College of Physicians.

Hypothalamic-pituitary, ovarian and adrenal contributions to polycystic ovary syndrome.

Polycystic ovary syndrome (PCOS) is a prevalent heterogeneous disorder linked with disturbances of reproductive, endocrine and metabolic function. The definition and aetiological hypotheses of PCOS are continually developing to incorporate evolving evidence of the syndrome, which appears to be both multifactorial and polygenic. The pathophysiology of PCOS encompasses inherent ovarian dysfunction that is strongly influenced by external factors including the hypothalamic-pituitary axis and hyperinsulinaemia. Neuroendocrine abnormalities including increased gonadotrophin-releasing hormone (GnRH) pulse frequency with consequent hypersecretion of luteinising hormone (LH) affects ovarian androgen synthesis, folliculogenesis and oocyte development. Disturbed ovarian-pituitary and hypothalamic feedback accentuates the gonadotrophin abnormalities, and there is emerging evidence putatively implicating dysfunction of the Kiss 1 system. Within the follicle subunit itself, there are intra-ovarian paracrine modulators, cytokines and growth factors, which appear to play a role. Adrenally derived androgens may also contribute to the pathogenesis of PCOS, but their role is less defined. Copyright © 2016. Published by Elsevier Ltd.

Polycystic ovary syndrome (PCOS) progression involves abnormal insulin signaling. SH2 domain-containing adaptor protein (Lnk) may be an important regulator of the insulin signaling pathway. We investigated whether Lnk was involved in insulin resistance (IR). Thirty-seven women due to receive laparoscopic surgery from June 2011 to February 2012 were included from the gynecologic department of the Sun Yat-Sen Memorial Hospital, Sun Yat-Sen University. Samples of polycystic and normal ovary tissues were examined by immunohistochemistry. Ovarian cell lines underwent insulin stimulation and Lnk overexpression. Expressed Lnk underwent coimmunoprecipitation tests with green fluorescent protein-labeled insulin receptor and His-tagged insulin receptor substrate 1 (IRS1), and their colocalization in HEK293T cells was examined. Ovarian tissues from PCOS patients with IR exhibited higher expression of Lnk than ovaries from normal control subjects and PCOS patients without IR; mainly in follicular granulosa cells, the follicular fluid and plasma of oocytes in secondary follicles, and atretic follicles. Lnk was coimmunoprecipitated with insulin receptor and IRS1. Lnk and insulin receptor/IRS1 locations overlapped around the nucleus. IR, protein kinase B (Akt), and ERK1/2 activities were inhibited by Lnk overexpression and inhibited further after insulin stimulation, whereas IRS1 serine activity was increased. Insulin receptor (Tyr1150/1151), Akt (Thr308), and ERK1/2 (Thr202/Tyr204) phosphorylation was decreased, whereas IRS1 (Ser307) phosphorylation was increased with Lnk overexpression. In conclusion, Lnk inhibits the phosphatidylinositol 3 kinase-AKT and MAPK-ERK signaling response to insulin. Higher expression of Lnk in PCOS suggests that Lnk probably plays a role in the development of IR.

Thirty-seven women due to receive laparoscopic surgery from June 2011 to February 2012 were included from the gynecologic department of the Sun Yat-Sen Memorial Hospital, Sun Yat-Sen University. Samples of polycystic and normal ovary tissues were examined by immunohistochemistry. Ovarian cell lines underwent insulin stimulation and Lnk overexpression. Expressed Lnk underwent coimmunoprecipitation tests with green fluorescent protein-labeled insulin receptor and His-tagged insulin receptor substrate 1 (IRS1), and their colocalization in HEK293T cells was examined. Ovarian tissues from PCOS patients with IR exhibited higher expression of Lnk than ovaries from normal control subjects and PCOS patients without IR; mainly in follicular granulosa cells, the follicular fluid and plasma of oocytes in secondary follicles, and atretic follicles. Lnk was coimmunoprecipitated with insulin receptor and IRS1. Lnk and insulin receptor/IRS1 locations overlapped around the nucleus. IR, protein kinase B (Akt), and ERK1/2 activities were inhibited by Lnk overexpression and inhibited further after insulin stimulation, whereas IRS1 serine activity was increased. Insulin receptor (Tyr1150/1151), Akt (Thr308), and ERK1/2 (Thr202/Tyr204) phosphorylation was decreased, whereas IRS1 (Ser307) phosphorylation was increased with Lnk overexpression. In conclusion, Lnk inhibits the phosphatidylinositol 3 kinase-AKT and MAPK-ERK signaling response to insulin. Higher expression of Lnk in PCOS suggests that Lnk probably plays a role in the development of IR. PMID:27459314

Polycystic ovary syndrome (PCOS) is an endocrinological abnormality which typically presents as hormones disorder and/or infertility. It has received more and more attention in recent years though its pathogenesis is still unclear. Ovarian mucinous adenoma is a rarely pathological type which generates from epithelial cell of ovary. Here we present a patient with PCOS and ovarian mucinous tumor (occasionally discovered by cesarean section) receiving a complete relief after benign ovarian tumor excision. In this case, tumor excision played as a partial resection of ovary which might result in the normalized concentration level of hormones and morphology of ovary. This report suggests that therapeutic strategies for PCOS should be considered more carefully and individually.

Dermatologists are in a key position to treat the manifestations of polycystic ovary syndrome (PCOS). The management of PCOS should be tailored to each woman's specific goals, reproductive interests, and particular constellation of symptoms. Therefore, a multidisciplinary approach is recommended. In part II of this continuing medical education article, we present the available safety and efficacy data regarding treatments for women with acne, hirsutism, and androgenetic alopecia. Therapies discussed include lifestyle modification, topical therapies, combined oral contraceptives, antiandrogen agents, and insulin-sensitizing drugs. Treatment recommendations are made based on the current available evidence. Copyright © 2014 American Academy of Dermatology, Inc. Published by Elsevier Inc. All rights reserved.

To formulate clinical consensus recommendations for screening depression, anxiety, health-related quality of life (HRQoL), and disordered eating symptoms in women with polycystic ovary syndrome (PCOS) and review prevalence based on phenotypes and ethnicity, changes over time, etiology, and impact of treatment. Systematic reviews and preparation of position statement. Not applicable. Women with PCOS and controls screened using validated tools. None. Depressive symptoms, anxiety symptoms, disordered eating, and HRQoL scores. Several studies demonstrate that women with PCOS have an increased prevalence of higher depression and anxiety scores and higher odds of moderate and severe depressive and anxiety symptoms compared with controls. Obesity, hyperandrogenism, and fertility have a weak association with these symptoms. HRQoL scores are consistently reduced in PCOS, with infertility and weight concerns having the most significant impact. Some studies suggest an increased prevalence of disordered eating in women with PCOS compared with controls. The few studies that have evaluated the impact of PCOS-related treatments (lifestyle interventions and pharmacotherapy) show no detrimental effect or some improvement in depressive and anxiety symptoms and HRQoL scores. In women with PCOS, screening for depressive and anxiety symptoms should be offered at the time of diagnosis and screening for disordered eating should be considered. Further research is required across PCOS phenotypes, in longitudinal cohorts and on impact of therapy on depressive and anxiety syptoms, HRQOL, and disordered eating.

Polycystic ovary syndrome (PCOS) affects approximately 7% of the reproductive-age women. A growing body of evidence indicated that epigenetic mechanisms contributed to the development of PCOS. The role of DNA modification in human PCOS ovary granulosa cell is still unknown in PCOS progression. Global DNA methylation and hydroxymethylation were detected between PCOS' and controls' granulosa cell. Genome-wide DNA methylation was profiled to investigate the putative function of DNA methylaiton. Selected genes expressions were analyzed between PCOS' and controls' granulosa cell. Our results showed that the granulosa cell global DNA methylation of PCOS patients was significant higher than the controls'. The global DNA hydroxymethylation showed low level and no statistical difference between PCOS and control. 6936 differentially methylated CpG sites were identified between control and PCOS-obesity. 12245 differential methylated CpG sites were detected between control and PCOS-nonobesity group. 5202 methylated CpG sites were significantly differential between PCOS-obesity and PCOS-nonobesity group. Our results showed that DNA methylation not hydroxymethylation altered genome-wide in PCOS granulosa cell. The different methylation genes were enriched in development protein, transcription factor activity, alternative splicing, sequence-specific DNA binding and embryonic morphogenesis. YWHAQ, NCF2, DHRS9 and SCNA were up-regulation in PCOS-obesity patients with no significance different between control and PCOS-nonobesity patients, which may be activated by lower DNA methylaiton. Global and genome-wide DNA methylation alteration may contribute to different genes expression and PCOS clinical pathology.

The sympathetic nervous system in polycystic ovary syndrome: a novel therapeutic target?

PubMed

Lansdown, Andrew; Rees, D Aled

2012-12-01

Polycystic ovary syndrome (PCOS) is a common endocrine condition associated with long-term health risks, including type 2 diabetes and vascular dysfunction in addition to reproductive sequelae. Many of the common features of PCOS, such as central obesity, hyperinsulinaemia and obstructive sleep apnoea (OSA), are associated with chronic sympathetic overactivity, suggesting that sympathoexcitation may be involved in the pathogenesis of this condition. Rodent models of polycystic ovaries have shown that ovarian sympathetic outflow may be increased, accompanied by elevated intra-ovarian synthesis of nerve growth factor (NGF) which may be involved in initiation of ovarian pathology. Patients with PCOS have evidence of increased muscle sympathetic nerve activity (MSNA), altered heart rate variability and attenuated heart rate recovery postexercise, compared with age- and BMI-matched controls, suggesting a generalized increase in sympathetic nerve activity. Active weight loss can reduce MSNA and whole body noradrenaline spillover, whereas low-frequency electroacupuncture decreased MSNA in overweight women with PCOS. Treatment of OSA with continuous positive airways pressure may reduce plasma noradrenaline levels and diastolic blood pressure and improve cardiac sympathovagal balance. Renal sympathetic denervation also reduced MSNA, noradrenaline spillover and blood pressure in two PCOS subjects with hypertension, accompanied by improved insulin sensitivity. The sympathetic nervous system may thus offer a new therapeutic target in PCOS but larger and longer-term studies are needed before these treatments can be considered in clinical practice. © 2012 Blackwell Publishing Ltd.

Role of androgen excess on metabolic aberrations and cardiovascular risk in women with polycystic ovary syndrome.

PubMed

Christakou, Charikleia D; Diamanti-Kandarakis, Evanthia

2008-11-01

Polycystic ovary syndrome (PCOS) is associated with a clustering of metabolic and cardiovascular risk factors. Insulin resistance is implicated as the major player in the metabolic abnormalities and contributes to the increased cardiovascular risk associated with the syndrome. However, androgen excess appears to participate as an independent parameter, which further aggravates the cardiovascular and metabolic aberrations in affected women with PCOS. The resultant impact of hyperandrogenemia possibly acquires clinical significance for women's health in the context of PCOS, particularly since recent data support an increased incidence of coronary artery disease and of cardiovascular events directly related to androgen levels in women with the syndrome.

To measure macrophage migration inhibitory factor (MIF) concentrations in obese and non-obese women diagnosed with polycystic ovary syndrome (PCOS). Women diagnosed with PCOS and age-matched healthy controls with regular menses and normal ovaries on ultrasound examination were selected and divided into 4 groups (group A, PCOS and obese; group B, PCOS and non-obese; group C, obese controls; and group D, non-obese controls) based on body mass index (obese >30 kg/m2 and non-obese <25 kg/m2). Luteinizing hormone, follicle-stimulating hormone, androstenedione, testosterone, sex hormone-binding globulin, serum glucose, insulin and MIF levels were measured. Obese and non-obese women with PCOS had higher luteinizing hormone, follicle-stimulating hormone, androstenedione, testosterone, and insulin levels as compared to the obese and non-obese control groups, respectively (P < .0001). Women with PCOS had significantly higher MIF levels (group A, 48.6 ± 9.9 mg/ml; group B, 35.2 ± 6.0 ng/ml) as compared to controls (group C, 13.5 ± 6.0 ng/ml; group D, 12.0 ± 4.3 ng/dl; P < .0001). A weak, positive and significant correlation was seen between fasting blood glucose and insulin levels in women with PCOS (P < .05). Significant differences exist in plasma MIF levels between obese and non-obese women with and without PCOS. Copyright © 2014 SEEN. Published by Elsevier Espana. All rights reserved.

Polycystic ovary syndrome (PCOS) is a common endocrinopathy in premenopausal women, associated with risk of metabolic syndrome and cardiovascular disease (CVD). CVD risk evaluation is recommended for PCOS patients. This study aimed to evaluate the risk of CVD in PCOS patients and to identify the best predictors for metabolic and cardiovascular disturbances. The study included 169 PCOS patients and 110 healthy women in reproductive age. We estimated cardiovascular risk according to American Heart Association and Androgen Excess-PCOS Society criteria that classified patients as metabolically unhealthy (MU) or metabolically healthy (MH). The PCOS group had significantly higher body mass index (BMI), waist circumference, and waist-to-hip ratio (P < 0.000001). Metabolic syndrome was only defined among PCOS patients (8.9%). No obesity was observed in the control group. Waist circumference ≥ 80 cm was presented in 44% of PCOS patients in comparison to 14.5% of control participants (P < 0.000001). There was a significant tendency for higher fasting insulin levels in the PCOS population (P < 0.00001). Surprisingly the PCOS-MH group had the highest high-density lipoprotein (HDL) levels. ROC curves were used to indicate parameters diagnosing metabolically unhealthy women and revealed that WC, BMI and HC seem to be the strongest predictors of metabolic disturbances in PCOS but in the healthy population in reproductive age biochemical findings such as low HDL or increased fasting glycemia presented stronger predictive value than patients' anthropometric features. Physicians need to remember to adopt different diagnostic approach while seeking metabolic complications in these different groups of women.

Exercise therapy in polycystic ovary syndrome.

PubMed

Hoeger, Kathleen M

2008-01-01

Women with polycystic ovary syndrome (PCOS) demonstrate a high prevalence of obesity across all populations studied. The role of decreased energy expenditure through reduced physical activity in contributing to obesity in PCOS is not well studied. The independent benefits of exercise in improving metabolic disease, cardiovascular health, and diabetes have been shown in the general population. Moderate activity incorporated into daily activities appears to be as effective in the reduction in diabetes risk and cardiovascular disease as that achieved with vigorous activity and may be more sustainable over the long-term. The role of physical activity in the management of the reproductive dysfunction of PCOS is less established, although lifestyle change incorporating increased physical activity with reduced caloric intake has shown benefit in small published trials. Studies of weight loss demonstrate an essential role for increased physical activity in maintenance of weight loss over the long-term although minimal effect in the achievement of weight loss with exercise alone. Further studies of the role for exercise in the management of reproductive dysfunction in PCOS as well as clarification of the type, frequency, and duration of exercise to achieve the best outcomes are needed.

to compare clinical and laboratory parameters in women with polycystic ovary syndrome (PCOS) using metformin or combined oral contraceptive (COC) after 6 months. retrospective study analyzing records of patients with PCOS using the Androgen Excess and Polycystic Ovary Syndrome (AE-PCOS) Society criteria. The groups were: I-COC (21 tablets, pause of 7 days; n=16); II-metformin (850 mg 12/12h, n=16); III-COC plus metformin (n=9). Body mass index (BMI), acne (% of improvement), modified Ferriman-Gallway index and menstrual cycle index (MCI), luteinizing hormone (LH), follicle-stimulating hormone (FSH), total testosterone (TT), androstenedione (A) and homeostasis model assessment: insulin resistance (HOMA-IR) index were assessed Results: isolated use of COC compared to metformin was better regarding to acne, Ferriman index, MCI, LH, TT and A levels. On the other hand, metformin was better in the HOMA-IR index (4.44 and 1.67 respectively, p=0.0007). The association COC plus metformin, compared to metformin alone shows the maintenance of improvement of acne, Ferriman index, MCI, and testosterone levels. The HOMA-IR index remained lower in the metformin alone group (4.19 and 1.67, respectively; p=0,046). The comparison between COC plus metformin and COC alone, in turn, shows no difference in the improvement of acne, Ferriman index, MCI, LH, TT and A levels, indicating that the inclusion of metformin did not lead to additional benefits in these parameters. Still, the HOMA-IR index was similar in both groups (4.19 and 4.44 respectively; p=0.75), showing that the use of metformin associated with COC may not improve insulin resistance as much as it does if used alone. our data suggest that the combination of metformin and contraceptive does not improve insulin resistance as observed with metformin alone.

To assess the importance of the menstrual pattern as a marker for clinical and laboratory alterations related to metabolic syndrome (MS) and polycystic ovary syndrome (PCOS) among Brazilian adolescents. A cross-sectional study. Endocrine Gynecology Outpatient Clinic of the Adolescent Health Studies Center (NESA) at the Pedro Ernesto University Hospital. 59 girls (12-19 years old) were classified by their menstrual cycles as regular (n = 23) and irregular (n = 36). None. Biochemical collections were made of peripheral blood after fasting for 12 hours, and the oral glucose tolerance test with 75 g of anhydrous glucose. PCOS, MS, and the criteria for MS were significantly more frequent (P < .05) in the subgroup with irregular menstruation. Adolescents with irregular cycles presented a significant increase in waist circumference, glycemia 2 hours after oral glucose overload (2 h), fasting and 2-h insulin, HOMA-IR, and triglycerides. In contrast, the glucose/insulin ratio, quantitative insulin-sensitivity check index, and HDL serum levels were significantly lower among patients with irregular menstruation, compared to those with regular cycles. In the logistic regression, we noted that insulin 2 h ≥ 75 μIU/mL (r = 1.90; P = .018), waist circumference > 95 cm (r = 2.21; P = .006) and diagnosis of PCOS (r = 1.93; P = .023) were significantly correlated to irregular cycles. We concluded that close observation of menstrual cycle patterns is an important tool for identifying adolescents at higher risk of developing PCOS and MS.

To evaluate the electrical activity of the pelvic floor muscles (PFM) in women with polycystic ovary syndrome. Forty-two women with polycystic ovary syndrome (PCOS group) and 13 premenopausal women (control group) were recruited in this cross-sectional study. Total testosterone and estradiol were measured and muscle tone and maximum voluntary contraction (MVC) of PFM were determined by surface electromyography. There was a difference in muscle tone (PCOS = 59.9 µV and Control group = 25.5 µV; P < 0.0001) and MVC (PCOS = 159.7 µV and Control group = 63.7 µV; P < 0.0002) between groups. The concentration of estradiol and testosterone showed a strong correlation with tone (r = 0.9, r = 0.8 respectively) and MVC (r = 0.9, r = 0.9 respectively) in women with PCOS. The control group exhibited a strong correlation between testosterone and muscle tone (r = 0.9) and MVC (r = 0.9). Women with PCOS display higher electromyographic values than those in premenopause. Moreover, electrical activity showed a positive relation with estradiol and testosterone concentrations. Although PCOS is a heterogeneous disorder affecting young women, it is suggested that the hyperandrogenic state associated with PCOS is a protective factor for PFM. Neurourol.

Polycystic ovary syndrome (PCOS) is associated with increased cardiovascular disease risk. The effect of weight loss on the vascular inflammatory markers plasminogen activator inhibitor-1 (PAI-1), asymmetric dimethylarginine (ADMA), soluble vascular cell adhesion molecule-1 (sVCAM-1) and intracellular adhesion molecule-1 (sICAM-1) is unknown. Overweight women with (n=14) and without (n=13) PCOS of comparable age and body mass index undertook an 8-week weight-loss programme. Women with PCOS had elevated PAI-1, sVCAM-1 and sICAM-1 before and after weight loss compared with the controls. For all women, sVCAM-1 (P=0.026) and sICAM-1 (P=0.04) decreased with weight loss. Women with PCOS have elevated inflammatory markers, which are partially reduced by weight loss. Copyright © 2012 Reproductive Healthcare Ltd. Published by Elsevier Ltd. All rights reserved.

To compare clomiphene citrate plus N-acetyl cysteine versus clomiphene citrate for inducing ovulation in patients with polycystic ovary syndrome. Prospective cross-over trial. University teaching hospital and a private practice setting. Five hundred and seventy-three patients were treated with clomiphene citrate for one menstrual cycle among which 470 patients were treated with clomiphene citrate plus N-acetyl cysteine for another cycle. All women suffered from polycystic ovary syndrome. Patients had clomiphene citrate 50-mg tablets twice daily alone or with N-acetyl cysteine 1,200 mg/day orally for 5 days starting on day 3 of the menstrual cycle. Primary outcomes were number of mature follicles, serum E2, serum progesterone, and endometrial thickness. Secondary outcome was the occurrence of pregnancy. Ovulation rate improved significantly after the addition of N-acetyl cysteine (17.9% versus 52.1%). Although the number of mature follicles was more in the N-acetyl cysteine group (2.1+/-0.88 versus 3.2+/-0.93), the difference was not statistically significant. The mean E2 levels (pg/ml) at the time of human chorionic gonadotropine injection, serum progesterone levels (ng/ml) on days 21-23 of the cycle, and the endometrial thickness were significantly improved in the N-acetyl cysteine group. The overall pregnancy rate was 11.5% in the N-acetyl cysteine group. Insulin resistance occurred in 260 patients (55.4%). There was no significant difference between the insulin resistance group (n = 260) and non-insulin resistance group (n = 210) as regards ovulation rate, number of follicles, serum E2 (pg/ml), serum progesterone (ng/ml), endometrial thickness (mm), or pregnancy rate. N-Acetyl cysteine is proved effective in inducing or augmenting ovulation in polycystic ovary patients.

Obesity has been linked with a host of metabolic and reproductive disorders including polycystic ovary syndrome (PCOS). While a clear association exists between obesity and PCOS, the exact nature of this relationship remains unexplained. The primary symptoms of PCOS include hyperandrogenism, anovulation, and polycystic ovaries. Most animal models utilize androgen treatments to induce PCOS. However, these models often fail to address the underlying causes of the disease and do not effectively reproduce key metabolic features such as hyperinsulinemia. Here, we present a novel rodent model of diet-induced obesity that recapitulates both the metabolic and reproductive phenotypes of human PCOS. Rats on a high-fat high-sugar (HFHS) diet not only demonstrated signs of metabolic impairment, but they also developed polycystic ovaries and experienced irregular estrous cycling. Though hyperandrogenism was not characteristic of HFHS animals as a group, elevated testosterone levels were predictive of high numbers of ovarian cysts. Alterations in steroidogenesis and folliculogenesis gene expression were also found via RNA sequencing of ovarian tissue. Importantly, the PCOS-like symptoms induced in these rats may share a similar etiology to PCOS in humans. Therefore, this model offers a unique opportunity to study PCOS at its genesis rather than following the development of disease symptoms.

Polycystic ovary syndrome is a common endocrinopathy in reproductive-age women, and associates with insulin resistance. Exercise is advocated in this disorder, but little knowledge exists on the optimal exercise regimes. We assessed the effects of high intensity interval training and strength training on metabolic, cardiovascular, and hormonal outcomes in women with polycystic ovary syndrome. Three-arm parallel randomized controlled trial. Thirty-one women with polycystic ovary syndrome (age 27.2 ± 5.5 years; body mass index 26.7 ± 6.0 kg/m2) were randomly assigned to high intensity interval training, strength training, or a control group. The exercise groups exercised three times weekly for 10 weeks. The main outcome measure was change in homeostatic assessment of insulin resistance (HOMA-IR). HOMA-IR improved significantly only after high intensity interval training, by -0.83 (95% confidence interval [CI], -1.45, -0.20), equal to 17%, with between-group difference (p = 0.014). After high intensity interval training, high-density lipoprotein cholesterol increased by 0.2 (95% CI, 0.02, 0.5) mmol/L, with between group difference (p = 0.04). Endothelial function, measured as flow-mediated dilatation of the brachial artery, increased significantly after high intensity interval training, by 2.0 (95% CI, 0.1, 4.0) %, between-group difference (p = 0.08). Fat percentage decreased significantly after both exercise regimes, without changes in body weight. After strength training, anti-Müllarian hormone was significantly reduced, by -14.8 (95% CI, -21.2, -8.4) pmol/L, between-group difference (p = 0.04). There were no significant changes in high-sensitivity C-reactive protein, adiponectin or leptin in any group. High intensity interval training for ten weeks improved insulin resistance, without weight loss, in women with polycystic ovary syndrome. Body composition improved significantly after both strength training and high intensity interval training. This pilot study

Polycystic ovary syndrome (PCOS) affects 12-21% of women in the childbearing age and is the most common cause of hyperandrogenaemia and anovulatory infertility. There is an increase in insulin resistance in both overweight and lean women with PCOS. Exercise treatment is mandatory among the overweight women due to sufficient evidence that it can improve the signs and symptoms of PCOS. This has not been fully investigated among the lean. However, new randomized controlled trials show that structured physical exercise can also improve insulin sensitivity, hyperandrogenaemia and menstrual frequency in lean women with PCOS.

Excess of Nerve Growth Factor in the Ovary Causes a Polycystic Ovary-Like Syndrome in Mice, which Closely Resembles Both Reproductive and Metabolic Aspects of the Human Syndrome

Polycystic ovarian syndrome (PCOS), the most common female endocrine disorder of unknown etiology, is characterized by reproductive abnormalities and associated metabolic conditions comprising insulin resistance, type 2 diabetes mellitus, and dyslipidemia. We previously reported that transgenic overexpression of nerve growth factor (NGF), a marker of sympathetic hyperactivity, directed to the ovary by the mouse 17α-hydroxylase/C17–20 lyase promoter (17NF mice), results in ovarian abnormalities similar to those seen in PCOS women. To investigate whether ovarian overproduction of NGF also induces common metabolic alterations of PCOS, we assessed glucose homeostasis by glucose tolerance test, plasma insulin levels, and body composition by dual-energy x-ray absorptiometry scan in young female 17NF mice and wild-type mice. 17NF mice exhibited increased body weight and alterations in body fat distribution with a greater accumulation of visceral fat compared with sc fat (P < .01). 17NF mice also displayed glucose intolerance (P < .01), decreased insulin-mediated glucose disposal (P < .01), and hyperinsulinemia (P < .05), which, similar to PCOS patients, occurred independently of body weight. Additionally, 17NF mice exhibited increased sympathetic outflow observed as increased interscapular brown adipose tissue temperature. This change was evident during the dark period (7 pm to 7 am) and occurred concomitant with increased interscapular brown adipose tissue uncoupling protein 1 expression. These findings suggest that overexpression of NGF in the ovary may suffice to cause both reproductive and metabolic alterations characteristic of PCOS and support the hypothesis that sympathetic hyperactivity may contribute to the development and/or progression of PCOS.

Polycystic ovary syndrome (PCOS) is a disorder characterized by hyperandrogenism, ovulatory dysfunction, and polycystic ovaries. Little is known about cardiovascular risk factors in patients with PCOS. We investigated plasma markers of cardiovascular disease in Saudi women with PCOS, with an emphasis on asymmetric dimethylarginine (ADMA) and total homocysteine (tHcy). Fifty Saudi women with PCOS diagnosed by the Rotterdam criteria (mean age [SD] 30.2 [3.0] years) and 40 controls without PCOS (mean age 29.3 [2.5] years) had measyrements taken of clinical, metabolic, and hormonal parameters, including plasma ADMA, tHcy, lipoprotein (a) ([Lp(a)], and serum high sensitivity C-reactive protein (hs-CRP), nitric oxid, and fibrinogen. Insulin resistance was calculated by the homeostasis model assessment (HOMA-IR). Women with PCOS had significantly higher fasting insulin, HOMA-IR, and luteinizing hormone (LH) levels than healthy controls (P P P CONCLUSION: Our study revealed that Saudi women with PCOS had a significantly different levels of plasma markers of cardiovascular disease compared with normal controls. Therefore, clinicians who manage women with PCOS should follow up on these markers to reduce the risk of cardiovascular disease.

Polycystic Ovary Syndrome (PCOS) is a common cause of female infertility and first line treatment is currently oral clomiphene citrate, a selective estrogen receptor modulator, which results in both a high nonresponse rate and multiple pregnancy rate. Aromatase inhibitors such as letrozole may have more favorable ovarian and endometrial effects. The goal of the Pregnancy in Polycystic Ovary Syndrome II (PPCOSII) study is to determine the safety and efficacy of clomiphene citrate (CC) compared to letrozole, in achieving live birth in infertile women with PCOS. The population will consist of 750 infertile women with PCOS. Additionally, the couple will have no other major infertility factor. This will be a multi-center, prospective, double-blind clinical trial of CC vs. letrozole for 5 treatment cycles (or approximately up to 25 weeks). The randomization scheme will be coordinated through the central data coordinating center (DCC) and the randomization is stratified by each participating site. After progestin withdrawal as needed, 750 women will be equally randomized to two different treatment arms: A) CC 50 mg every day for 5 days (day 3–7 of cycle), or B) letrozole 2.5 mg every day for 5 days (day 3–7 of cycle), for a total of 5 cycles or 25 weeks. The dose will be increased in subsequent cycles in both treatment groups for non-response or poor ovulatory response up to a maximum of 150 mg of CC a day (× 5 days) or 7.5 mg of letrozole a day (× 5 days). The primary analysis will use an intent-to-treat approach to examine differences in the live birth rate in the two treatment arms. PMID:22265923

To study the cardiometabolic profile characteristics and compare the prevalence of cardiovascular (CV) risk factors between women with different polycystic ovary syndrome (PCOS) phenotypes. A cross-sectional multicenter study analyzing 2,288 well phenotyped women with PCOS. Specialized reproductive outpatient clinic. Women of reproductive age (18-45 years) diagnosed with PCOS. Women suspected of oligo- or anovulation underwent a standardized screening consisting of a systematic medical and reproductive history taking, anthropometric measurements, and transvaginal ultrasonography followed by an extensive endocrinologic/metabolic evaluation. Differences in cardiometabolic profile characteristics and CV risk factor prevalence between women with different PCOS phenotypes, i.e., obesity/overweight, hypertension, insulin resistance, dyslipidemia, and metabolic syndrome. Women with hyperandrogenic PCOS (n=1,219; 53.3% of total) presented with a worse cardiometabolic profile and a higher prevalence of CV risk factors, such as obesity and overweight, insulin resistance, and metabolic syndrome, compared with women with nonhyperandrogenic PCOS. In women with nonhyperandrogenic PCOS overweight/obesity (28.5%) and dyslipidemia (low-density lipoprotein cholesterol≥3.0 mmol/L; 52.2%) were highly prevalent. Women with hyperandrogenic PCOS have a worse cardiometabolic profile and higher prevalence of CV risk factors compared with women with nonhyperandrogenic PCOS. However, all women with PCOS should be screened for the presence of CV risk factors, since the frequently found derangements at a young age imply an elevated risk for the development of CV disease later in life.

Data on glucose metabolism in Asian adolescents with polycystic ovary syndrome (PCOS) are limited. Glucose metabolism assessment using an oral glucose tolerance test (OGTT) in obese and lean Thai adolescents with PCOS, and a comparison between the two groups were done. Thirty-one patients (19 obese, 12 lean) were enrolled. Their median (range) age was 14.9 (11.0-21.0) years. Eighteen patients had abnormal glucose metabolism (13 hyperinsulinemia, 4 impaired glucose tolerance, and 1 diabetes). Compared between obese [median (range) BMI Z-score, 1.6 (1.2-2.6)] and lean [median (range) BMI Z-score, 0.1 (-1.4 to 0.6)] patients, the frequencies of each abnormal OGTT category, areas under the curves of glucose and insulin levels, and insulinogenic index were not different; however, insulin resistance was greater in the obese group. In conclusion, a high proportion of our adolescents with PCOS had abnormal glucose metabolism. Therefore, OGTT should be performed in adolescents with PCOS for the early detection of abnormal glucose metabolism.

Polycystic ovary syndrome is characterized by an excess in androgen levels, ovarian dysfunction, and polycystic ovarian morphology but is also associated with metabolic dysfunction and risk factors for cardiovascular disease. To our knowledge, there are few therapeutic recommendations for these cardiometabolic risk factors and little evidence of their long-term clinical relevance to cardiovascular health. To determine metabolic and/or cardiovascular outcomes in polycystic ovary syndrome treatment literature since the publication of the most recent Endocrine Society clinical practice guidelines in 2013. We searched PubMed using a string of variations of polycystic ovary syndrome, therapy/treatment, and adolescence, and we included English-language original research articles published while the 2013 clinical practice guidelines were disseminated (ie, articles published from January 1, 2011, to June 1, 2015). Articles that appeared relevant based on a review of titles and abstracts were read in full to determine relevancy. References from relevant articles were reviewed for additional studies. Four topic areas emerged: (1) lifestyle modification, (2) metformin vs placebo or estrogen-progestin oral contraceptives, (3) insulin-sensitizing agents, and (4) estrogen-progestin formulations. Most studies assessed the role of metformin as a monotherapy or dual therapy supplement and found significant benefit when including metformin in polycystic ovary syndrome treatment regimens. Studies showed improvements in cardiometabolic risk factors and, in several, androgen excess and cutaneous and menstrual symptoms. Studies were limited by sample size (range, 22-171), few adolescent participants, and short-term outcomes. Findings show potential for metformin and estrogen-progestin dual therapy but warrant longitudinal studies examining outcomes from adolescence through middle age to determine the effect on long-term cardiovascular health.

Polycystic ovary syndrome is a heterogeneous endocrine and metabolic disorder associated with abdominal obesity, dyslipidemia and insulin resistance. Since abdominal obesity is characterized by low-grade inflammation, the aim of the study was to investigate whether visceral adipose tissue inflammation linked to abdominal obesity and dyslipidemia could lead to impaired insulin sensitivity in the animal model of polycystic ovary syndrome.Female Wistar rats were treated with nonaromatizable 5α-dihydrotestosterone pellets in order to induce reproductive and metabolic characteristics of polycystic ovary syndrome. Glucose, triglycerides, non-esterified fatty acids and insulin were determined in blood plasma. Visceral adipose tissue inflammation was evaluated by the nuclear factor kappa B intracellular distribution, macrophage migration inhibitory factor protein level, as well as TNFα, IL6 and IL1β mRNA levels. Insulin sensitivity was assessed by intraperitoneal glucose tolerance test and homeostasis model assessment index, and through analysis of insulin signaling pathway in the visceral adipose tissue.Dihydrotestosterone treatment led to increased body weight, abdominal obesity and elevated triglycerides and non-esterified fatty acids, which were accompanied by the activation of nuclear factor kappa B and increase in macrophage migration inhibitory factor, IL6 and IL1β levels in the visceral adipose tissue. In parallel, insulin sensitivity was affected in 5α-dihydrotestosterone-treated animals only at the systemic and not at the level of visceral adipose tissue.The results showed that abdominal obesity and dyslipidemia in the animal model of polycystic ovary syndrome were accompanied with low-grade inflammation in the visceral adipose tissue. However, these metabolic disturbances did not result in decreased tissue insulin sensitivity. © Georg Thieme Verlag KG Stuttgart · New York.

To identify the androgen ratio that best predicts insulin resistance and metabolic syndrome among women with polycystic ovary syndrome (PCOS). Data for 180 women with PCOS and 180 healthy controls were extracted from two previous studies in Iran (conducted during 2008-2010 and 2011-2013). The diagnosis of PCOS was based on the Rotterdam criteria. The serum concentration of different androgens was measured. Receiver operating characteristic curve analysis was used to assess the ability of various androgen ratios to predict insulin resistance and metabolic syndrome. Among women with PCOS, the testosterone-to-androstenedione ratio was the best predictor of insulin resistance (sensitivity 0.83, specificity 0.42) and metabolic syndrome (sensitivity 0.85, specificity 0.70). Among healthy controls, the ratio of free androgen index to testosterone was the best predictor of insulin resistance (sensitivity 0.84, specificity 0.33) and metabolic syndrome (sensitivity 0.91, specificity 0.17). The prediction of insulin resistance and metabolic syndrome among women with PCOS was best accomplished with the testosterone-to-androstenedione ratio. © 2017 International Federation of Gynecology and Obstetrics.

BACKGROUND AND OBJECTIVES: Polycystic ovary syndrome (PCOS) is a disorder characterized by hyperandrogenism, ovulatory dysfunction, and polycystic ovaries. Little is known about cardiovascular risk factors in patients with PCOS. We investigated plasma markers of cardiovascular disease in Saudi women with PCOS, with an emphasis on asymmetric dimethylarginine (ADMA) and total homocysteine (tHcy). PATIENTS AND METHODS: Fifty Saudi women with PCOS diagnosed by the Rotterdam criteria (mean age [SD] 30.2 [3.0] years) and 40 controls without PCOS (mean age 29.3 [2.5] years) had measyrements taken of clinical, metabolic, and hormonal parameters, including plasma ADMA, tHcy, lipoprotein (a) ([Lp(a)], and serum high sensitivity C-reactive protein (hs-CRP), nitric oxid, and fibrinogen. Insulin resistance was calculated by the homeostasis model assessment (HOMA-IR). RESULTS: Women with PCOS had significantly higher fasting insulin, HOMA-IR, and luteinizing hormone (LH) levels than healthy controls (P<.001). Lipid profile, free androgen index (FAI), ADMA, tHcy, hsCRP, and Lp(a) were significantly higher in women with PCOS compared with healthy controls (P<.001). The women with PCOS had significantly lower nitric oxide and high-density lipoprotein cholesterol (HDL-C) levels compared with healthy controls (P<.001). CONCLUSION: Our study revealed that Saudi women with PCOS had a significantly different levels of plasma markers of cardiovascular disease compared with normal controls. Therefore, clinicians who manage women with PCOS should follow up on these markers to reduce the risk of cardiovascular disease. PMID:20622344

Nonalcoholic fatty liver disease (NAFLD) is the most common cause of chronic liver disease in the Western world comprising a spectrum of liver damage from fatty liver infiltration to end-stage liver disease, in patients without significant alcohol consumption. Increased prevalence of NAFLD has been reported in patients with polycystic ovary syndrome (PCOS), one of the most common endocrinopathies in premenopausal women, which has been redefined as a reproductive and metabolic disorder after the recognition of the important role of insulin resistance in the pathophysiology of the syndrome. Obesity, in particular central adiposity and insulin resistance are considered as the main factors related to NAFLD in PCOS. Moreover, existing data support that androgen excess, which is the main feature of PCOS and is interrelated to insulin resistance, may be an additional contributing factor to the development of NAFLD. Although the natural history of NAFLD remains unclear and hepatic steatosis seems to be a relatively benign condition in most patients, limited data imply that advanced stage of liver disease is possibly more frequent in obese PCOS patients with NAFLD. PCOS patients, particularly obese patients with features of the metabolic syndrome, should be submitted to screening for NAFLD comprising assessment of serum aminotransferase levels and of hepatic steatosis by abdominal ultrasound. Lifestyle modifications including diet, weight loss and exercise are the most appropriate initial therapeutic interventions for PCOS patients with NAFLD. When pharmacologic therapy is considered, metformin may be used, although currently there is no medical therapy of proven benefit for NAFLD. Long-term follow up studies are needed to clarify clinical implications and guide appropriate diagnostic evaluation, follow-up protocol and optimal treatment for PCOS patients with NAFLD.

Polycystic ovary syndrome (PCOS) is the most common, heterogeneous, and multifactorial endocrine disorder in premenopausal women. The pathophysiology of this endocrinopathy is still unclear; however, the heterogeneity of its features within ethnic races, geographic location, and families suggests that environment and lifestyle are of prime importance. This work is mainly focused on the possible role of the most common and studied environmental toxins for this syndrome in the pathogenesis of PCOS. Plasticizers, such as bisphenol A (BPA) or phthalates, which belong to the categories of endocrine disrupting chemicals (EDCs) and advanced glycation end products (AGEs), affect humans' health in everyday, industrialized life; therefore special attention should be paid to such exposure. Timing of exposure to EDCs is crucial for the intensity of adverse health effects. It is now evident that fetuses, infants, and/or young children are the most susceptible groups, especially in the early development periods. Prenatal exposure to EDCs that mimic endogenous hormones may contribute to the altered fetal programming and in consequence lead to PCOS and other adverse health effects, potentially transgenerationally. Acute or prolonged exposure to EDCs and AGEs through different life cycle stages may result in destabilization of the hormonal homeostasis and lead to disruption of reproductive functions. They may also interfere with metabolic alterations such as obesity, insulin resistance, and compensatory hyperinsulinemia that can exacerbate the PCOS phenotype and contribute to PCOS consequences such as type 2 diabetes and cardiovascular disease. Since wide exposure to environmental toxins and their role in the pathophysiology of PCOS are supported by extensive data derived from diverse scientific models, protective strategies and strong recommendations should be considered to reduce human exposure to protect present and future generations from their adverse health effects.

The present study investigated dietary intake, glucose metabolism and sex hormones in women with polycystic ovary syndrome (PCOS). A total of forty-five women (aged 25–40 years) with PCOS and 161 control women (aged 25–43 years) with non-PCOS-related infertility were recruited. Anthropometry, glucose tolerance and sex hormones were determined and dietary intake was assessed. Women with PCOS had lower serum sex hormone-binding globulin and increased BMI, waist:hip ratio, luteinising hormone, ratio of luteinising hormone: follicle-stimulating hormone, testosterone and free androgen index (FAI). Postprandial glucose, fasting insulin and insulin resistance were elevated in women with PCOS. Women with PCOS had reduced energy and carbohydrate intake but higher fat intake. Serum sex hormone-binding globulin level was negatively associated with BMI in both groups and negatively correlated with macronutrient intake in the PCOS group with hyperandrogenism. However, FAI was positively correlated with BMI, waist circumference and glucose metabolic parameters in both groups. Therefore, women with PCOS consume lower energy and carbohydrate compared with those with non-PCOS-related infertility and macronutrient intake is only negatively associated with serum sex hormone-binding globulin level in the PCOS group with hyperandrogenism.

Background: Polycystic ovary syndrome (PCOS) is the most prevalent endocrine disorder among fertile women. Studies show reduced quality of life, anxiety, depression, body dissatisfaction, eating disorder, and sexual dysfunction, but the etiology of these disturbs remains still debated. The aim of our study is to verify whether this hyperandrogenic syndrome characterizes a strong psycho(patho)logical personality. Method: Sixty PCOS subjects (mean age 25.8 ± 4.7 years) were evaluated by anthropometric, metabolic, hormonal, clinical, and psychological parameters. After the certainty of the diagnosis of PCOS, the Rorschach test, according to Exner’s comprehensive system (CS) and the Millon Clinical Multiaxial Inventory-III (MCMI-III) were administered to each patient. The control group, on which the comparison was carried out, was composed by 40 healthy and aged compared women who were exclusively administered the Rorschach test according to CS. Results: MCMI-III evidenced axis II DSM-IV personality disorders [4.1% schizoid, depressive, sadistic, negativistic (passive–aggressive), and masochistic, 6.1% avoiding, 12.2% dependent, 20.4% histrionic, 16.3% narcissistic, 2.0% obsessive–compulsive], and axis I DSM-IV psychiatric disorders: 10.2% anxiety, 2.0% somatoform disorder and bipolar disorder, 16.3% major depressive disorder. Finally, we found 44.9% delusional disorder and 4.1% thought disorder. Rorschach test’s results show 53.1% reduced coping abilities and social skills, 55.1% depression, 30.6% perceptual distortion and cognitive slippage, 24.5% constantly alert and worry, 8.1% at risk for suicide, and finally about 50% of our patients had chronic stress. Conclusion: PCOS women have relevant personality and psychiatric disorders, when compared with normal subjects. PMID:25429283

Yaks (Bos grunniens) are endemic species that can adapt well to thin air, cold temperatures, and high altitude. These species can survive in harsh plateau environments and are major source of animal production for local residents, being an important breed in the Qinghai-Tibet Plateau. However, compared with ordinary cattle that live in the plains, yaks generally have lower fertility. Investigating the basic physiological molecular features of yak ovary and identifying the biological events underlying the differences between the ovaries of yak and plain cattle is necessary to understand the specificity of yak reproduction. Therefore, RNA-seq technology was applied to analyze transcriptome data comparatively between the yak and plain cattle estrous ovaries. After deep sequencing, 3,653,032 clean reads with a total of 4,828,772,880 base pairs were obtained from yak ovary library. Alignment analysis showed that 16992 yak genes mapped to the yak genome, among which, 12,731 and 14,631 genes were assigned to Gene Ontology (GO) categories and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathways. Furthermore, comparison of yak and cattle ovary transcriptome data revealed that 1307 genes were significantly and differentially expressed between the two libraries, wherein 661 genes were upregulated and 646 genes were downregulated in yak ovary. Functional analysis showed that the differentially expressed genes were involved in various Gene Ontology (GO) categories and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathways. GO annotations indicated that the genes related to "cell adhesion," "hormonal" biological processes, and "calcium ion binding," "cation transmembrane transport" molecular events were significantly active. KEGG pathway analysis showed that the "complement and coagulation cascade" pathway was the most enriched in yak ovary transcriptome data, followed by the "cytochrome P450" related and "ECM-receptor interaction" pathways. Moreover, several novel pathways

Studies have demonstrated lipid differences among African-Americans and Caucasians and between women with polycystic ovary syndrome (PCOS) and normally ovulating women. However, few studies have examined racial differences in lipoprotein levels in women with PCOS. This study compared lipoprotein levels in African-American and Caucasian women with PCOS. We performed a retrospective chart review of 398 subjects seen as new patients for PCOS at the Duke University Medical Center Endocrinology Clinic in Durham, NC. We identified 126 charts appropriate for review, based on a diagnosis of PCOS (using the 1990 National Institutes of Health criteria), a self-reported race of either Caucasian or African-American, and a body mass index (BMI) higher than 25. We excluded patients taking glucophage, oral contraceptives, or lipid-lowering medications. Age, BMI, total cholesterol, high-density lipoprotein (HDL) cholesterol, non-HDL cholesterol, random triglycerides (TG), and oral glucose tolerance test measurements were collected and included in the analysis. African-American women with PCOS had higher HDL cholesterol levels (52.6 vs. 47.5 mg/dl, P = 0.019), lower non-HDL cholesterol (134.1 vs. 154.6 mg/dl, P = 0.046), and lower TG levels (97.5 vs. 168.2 mg/dl, P < 0.001) than Caucasian women. These differences could not be attributed to age, BMI, or differences in insulin resistance as determined by homeostasis model assessment of insulin resistance. African-American women with PCOS appear to have a more favorable lipid profile than Caucasian women with PCOS having higher HDL cholesterol, lower non-HDL cholesterol, and lower TG when BMI and insulin resistance are equal.

Hepatic manifestations of women with polycystic ovary syndrome.

Women with polycystic ovary syndrome (PCOS) have a higher prevalence of nonalcoholic fatty liver disease (NAFLD) and nonalcoholic steatohepatitis (NASH) than the general population. The link between NAFLD/NASH and PCOS is not just a coincidence. Indeed, both of these disorders comprise common risk factors, including central obesity, insulin resistance, chronic low-grade inflammation, and hyperandrogenemia. The characteristics of hyperandrogenemia in women with PCOS include elevated total and free testosterone levels and low sex hormone-binding globulin levels and are reported to be associated with NAFLD and elevated liver enzymes; however, not all elevated androgen levels in women with PCOS have the same adverse effects on the liver. With the exception of weight loss and encouraging exercise in obese women, few evidence-based effective treatments target NAFLD/NASH in women with PCOS. Selective antiandrogens and insulin sensitizers might be beneficial in treating NAFLD/NASH in women with PCOS, but further elucidation is needed. Copyright © 2016. Published by Elsevier Ltd.

The idea that diet can affect mood and behavior in women with polycystic ovary syndrome (PCOS) by altering blood glucose levels has become popular in recent years. This paper describes an online survey (N=462) of 24 women with PCOS, 299 healthy control women, 47 women who possibly had undiagnosed PCOS, and 92 men. The groups were compared for symptoms of mood and behavioral symptoms typical of reactive (postprandial) hypoglycemia. The outcome measures were two questionnaires that measure states associated with hypoglycemia: the Hypoglycemia Symptom Checklist-7 (HSC-7), which measures behavioral symptoms and the Mood Adjective Checklist (MACL), which measures emotional states. Controlling for age and body mass index (BMI) using between-groups analysis of covariance (ANCOVA), the women with PCOS scored significantly higher than the other three groups (p<0.001) on the outcome measures. These differences remained statistically significant in a subset of twelve women with PCOS compared to twelve healthy control women closely matched for age, BMI, and eating behavior. The findings are suggestive of hypoglycemia-related mood and behavioral problems in PCOS. Future research should test whether blood glucose levels correlate with these symptoms in PCOS, and whether a low glycemic index ('low-GI') diet improves the symptoms. Copyright © 2011 Elsevier Ltd.

Fetal programming of polycystic ovary syndrome

2015-01-01

Polycystic ovary syndrome (PCOS) is a common endocrine disorder that affects up to 6.8% of reproductive age women. Experimental research and clinical observations suggest that PCOS may originate in the very early stages of development, possibly even during intrauterine life. This suggests that PCOS is either genetically-transmitted or is due to epigenetic alterations that develop in the intrauterine microenvironment. Although familial cases support the role of genetic factors, no specific genetic pattern has been defined in PCOS. Several candidate genes have been implicated in its pathogenesis, but none can specifically be implicated in PCOS development. Hypotheses based on the impact of the intrauterine environment on PCOS development can be grouped into two categories. The first is the “thrifty” phenotype hypothesis, which states that intrauterine nutritional restriction in fetuses causes decreased insulin secretion and, as a compensatory mechanism, insulin resistance. Additionally, an impaired nutritional environment can affect the methylation of some specific genes, which can also trigger PCOS. The second hypothesis postulates that fetal exposure to excess androgen can induce changes in differentiating tissues, causing the PCOS phenotype to develop in adult life. This review aimed to examine the role of fetal programming in development of PCOS. PMID:26185601

2014-01-01

Polycystic ovary syndrome (PCOS) is a common endocrine disorder characterized by chronic oligoanovulation and hyperandrogenism and associated with insulin resistance, type 2 diabetes, and cardiovascular risk. In recent years, genetic studies have linked PCOS to a dinucleotide marker D19S884 in the fibrillin 3 gene. Fibrillins make up the major component of microfibrils in the extracellular matrix (ECM) and interact with molecules in the ECM to regulate transforming growth factor β (TGF-β) signaling. Therefore, variations in fibrillin 3 and subsequent dysregulation of TGF-β may contribute to the pathogenesis of PCOS. Here, we review the evidence from genetic studies supporting the role of TGF-β in PCOS and describe how TGF-β dysregulation may contribute to (1) the fetal origins of PCOS, (2) reproductive abnormalities in PCOS, and (3) cardiovascular and metabolic abnormalities in PCOS.

Polycystic ovary syndrome (PCOS) is a continuum of endocrine and reproductive disorders characterized by hyperandrogenism, antral follicle growth arrest and chronic inflammation. Macrophages play key role in inflammation and the balance between M1 (inflammatory) and M2 (anti-inflammatory) macrophages determines physiological/pathological outcomes. Here, we investigated if hyperandrogenism increases ovarian chemerin altering the balance of M1 and M2 macrophages and the granulosa cell death. Ovarian chemerin was up-regulated by 5α-dihydrotestosterone (DHT) in lean and overweight rats; while increased serum chemerin levels were only evident in overweight rats, suggesting that the serum chemerin may be reflective of a systemic response and associated with obesity, whereas increased ovarian chemerin expression is a localized response independent of the metabolic status. DHT altered follicle dynamics while increased the M1: M2 macrophages ratio in antral and pre-ovulatory follicles. While ovarian M1 macrophages expressing chemokine-like receptor 1 (CMKLR1) were increased, CMKLR1 + monocytes, which migrated towards chemerin-rich environment, were markedly decreased after 15 days of DHT. Androgen-induced granulosa cell apoptosis was dependent on the presence of macrophages. In humans, chemerin levels in follicular fluid, but not in serum, was higher in lean PCOS patients compared to BMI-matched controls and was associated with increased M1: M2 ratio. Our results support the concept that in PCOS, hyperandrogenemia increases chemerin expression while promotes CMKLR1 + monocytes recruitment and deregulates the immunological niche of ovaries. This study established a new immunological perspective in PCOS at the ovarian level. Hyperandrogenism is associated with up-regulation of chemerin and macrophage unbalance in the ovaries.

Classic polycystic ovary syndrome (PCOS) is a high-risk phenotype accompanied by increased risks of reproductive and metabolic abnormalities; however, the local metabolism characteristics of the ovaries and their effects on germ cell development are unclear. The present study used targeted metabolomics to detect alterations in the intermediate metabolites of follicular fluid from classic PCOS patients, and the results indicated that hyperandrogenism but not obesity induced the changed intermediate metabolites in classic PCOS patients. Regarding the direct contact, we identified mitochondrial function, redox potential, and oxidative stress in cumulus cells which were necessary to support oocyte growth before fertilization, and suggested dysfunction of mitochondria, imbalanced redox potential, and increased oxidative stress in cumulus cells of classic PCOS patients. Follicular fluid intermediary metabolic profiles provide signatures of classic PCOS ovary local metabolism and establish a close link with mitochondria dysfunction of cumulus cells, highlighting the role of metabolic signal and mitochondrial cross talk involved in the pathogenesis of classic PCOS.

The Androgen Excess and Polycystic Ovary Syndrome Society (AEPCOS) has recommended an updated threshold for polycystic ovarian morphology (PCOM) of 25 follicles or more, 10 ml or more of ovarian volume, or both. We describe the effect of these guidelines on reproductive and metabolic characteristics in 404 women. These women were separated into four groups: group A: hyperandrogenism and oligo-amenorrhoea (n = 157); group B: hyperandrogenism or oligo-amenorrhoea and PCOM meeting AEPCOS 2014 criteria (n = 125); group C: hyperandrogenism or oligo-amenorrhoea and PCOM meeting Rotterdam 2003 but not AEPCOS 2014 criteria (n = 72); and group D: non-PCOS not meeting either criteria (n = 50). Groups B, C and D did not differ across any metabolic markers. The AEPCOS 2014 guidelines may have limited utility in distinguishing metabolic risk factors and result in the exclusion of a large group of oligo-anovulatory women.

Evidence from various epidemiological studies and experimental animal studies has linked adverse intrauterine circumstances with health problems in adult life. This field of investigation is known as Developmental Origins of Health and Disease (DOHaD). Studies investigating the relation between developing polycystic ovary syndrome (PCOS) in adulthood and birth weight have yielded inconsistent results: PCOS is described more often in women with low birth weight and high birth weight, while other studies have failed to establish any relation. In this retrospective case-control study, we evaluated whether women diagnosed with PCOS had lower birth weight compared to women with a regular menstrual cycle (controls). Binary logistic regression models were used to analyze the data and correct for known confounders. About 65 women with PCOS and 96 controls were recruited for this purpose. The average birth weight of PCOS women (3357 g) did not differ from the average birth weight of controls (3409 g). Mean age at menarche differed significantly between groups, 13.7  years and 12.8  years (p = 0.006), respectively, for PCOS women and controls. In conclusion, we could not confirm the effect of adverse intrauterine conditions, reflected in birth weight, on developing PCOS.

Polycystic Ovary Syndrome: Insights into the Therapeutic Approach with Inositols

Sortino, Maria A.; Salomone, Salvatore; Carruba, Michele O.; Drago, Filippo

2017-01-01

Polycystic ovary syndrome (PCOS) is characterized by hormonal abnormalities that cause menstrual irregularity and reduce ovulation rate and fertility, associated to insulin resistance. Myo-inositol (cis-1,2,3,5-trans-4,6-cyclohexanehexol, MI) and D-chiro-inositol (cis-1,2,4-trans-3,5,6-cyclohexanehexol, DCI) represent promising treatments for PCOS, having shown some therapeutic benefits without substantial side effects. Because the use of inositols for treating PCOS is widespread, a deep understanding of this treatment option is needed, both in terms of potential mechanisms and efficacy. This review summarizes the current knowledge on the biological effects of MI and DCI and the results obtained from relevant intervention studies with inositols in PCOS. Based on the published results, both MI and DCI represent potential valid therapeutic approaches for the treatment of insulin resistance and its associated metabolic and reproductive disorders, such as those occurring in women affected by PCOS. Furthermore, the combination MI/DCI seems also effective and might be even superior to either inositol species alone. However, based on available data, a particular MI:DCI ratio to be administered to PCOS patients cannot be established. Further studies are then necessary to understand the real contents of MI or DCI uptaken by the ovary following oral administration in order to identify optimal doses and/or combination ratios.

To compare androgen responses during ACTH infusion among women with polycystic ovary syndrome (PCOS) and healthy women. Cross-sectional study. Academic medical center. Women with PCOS (n = 13) and healthy controls (n = 15). Blood samples were obtained frequently during a 6-hour dose-response ACTH infusion. Comparison of basal and stimulated levels of 17α-hydroxyprogesterone (17-OHP), androgens, and cortisol (F) during ACTH infusion with those after hCG injection within individual subjects. In women with PCOS increased 17-OHP, androstenedione (A), and DHEA responses during ACTH infusion were comparable to those observed in healthy controls. The magnitude of responses was highly variable among women with PCOS. Within individual women with PCOS adrenal responses to ACTH and ovarian responses to hCG were significantly correlated. Cortisol responses to ACTH were similar in women with PCOS and healthy controls. Within individual women with PCOS, enhanced androgen responses to ACTH are accompanied by comparable androgen responsiveness to hCG. These findings suggest that dysregulated steroidogenesis leading to hyperandrogenemia in this disorder is likely present in both adrenal and ovarian tissues. NCT00747617.

Obesity is a major factor in development of insulin resistance (IR) and metabolic features in polycystic ovary syndrome (PCOS) patients. Nearly two-thirds patients with PCOS (30 of 37 confirmed cases of PCOS) in our previous community based study were lean, in contrast to Caucasians. Metabolic parameters including IR and β cell function have not been characterized well in this group of lean PCOS. To study the metabolic features including IR and β cell function in lean PCOS patients, 53 patients with BMI, <23 kg/m 2 were compared with 71 obese PCOS and 45 age and body mass index matched controls. Lean patients had similar β cell function and IR as compared to controls and obese patients, though the latter group had more metabolic abnormality. Fasting c-peptide and its ratio to glucose were significantly higher in lean patients compared to controls. In subset of subjects with five point OGTT, disposition index and Matsuda index (MI) showed significant negative correlation with BMI and blood pressure. MI also negatively correlated with waist, WHR, and HOMAB. High fasting C-peptide is probably a class effect as is seen in both lean and obese PCOS.

The aim of this study was to systematically compare the clinical efficacy and safety of letrozole with clomiphene citrate for ovulation induction in women with polycystic ovary syndrome (PCOS). The Cochrane Central Register of Controlled Trials, PubMed, EMbase, CBMdisc and CNKI were searched for eligible randomized controlled trials (RCT) comparing letrozole with clomiphene citrate in PCOS patients. Two reviewers independently extracted information and evaluated methodological quality according to the Cochrane Handbook 5.0. Meta-analysis was performed with the fixed-effects model or random-effects model according to the heterogeneity. Six eligible RCT involving 841 patients were included. Letrozole was associated with a number of lower mature follicles per cycle (standardized mean difference (SMD) -1.41; 95% confidence intervales (CI) -1.54 to -1.28; P<0.00001) compared with clomiphene citrate. There were no significant differences in pregnancy rate (relative risk (RR) 0.97; 95% CI 0.79 to 1.18), abortion rate (RR 1.38; 95% CI 0.48 to -3.96) and multiple pregnancy rate (RR 0.34; 95% CI 0.07 to -1.72) between the two groups. The evidence from ovulation rates was not enough to support either letrozole or clomiphene citrate. In conclusion, letrozole is as effective as clomiphene citrate for ovulation induction in patients with PCOS. Copyright © 2011 Reproductive Healthcare Ltd. Published by Elsevier Ltd.

For to determine the effect of Diamel on the insulin resistance, insulin sensitivity, and sexual hormones results in women with polycystic ovary syndrome (PCOS). A study was carried out on 37 patients with this disorder. A triple-blind clinical trial was designed in which the Diamel food supplement was compared with a placebo. The women with reproductive ages were randomly distributed in two groups, with 18 and 19 women respectively, and they took Diamel or placebo and were followed up during 6 months with clinical and biochemical evaluation. A significant decrease in the HOMA-IR from the initial value at six months was observed in the group with Diamel. The insulin sensitivity improved considerably in this group. The rate of menstrual recovery was higher in the group with Diamel, and two patients from this group obtained pregnancy. The hormone levels shows a significant decrease in testosterone at 3 months in the group with Diamel compared with the control group. The LH also decreases in the same group when comparing the start with 6 months.We concluded that the Diamel decreases insulin resistance and improves sensitivity to this hormone in women with PCOS, with improvement in the levels of LH and testosterone.

Is it possible to distinguish metabolically healthy polycystic ovary syndrome (MH-PCOS) from metabolically unhealthy PCOS (MU-PCOS) by simple diagnostic tools such as body mass index (BMI), waist/hip ratio (WHR), at-risk category suggested by Androgen Excess Society (AES) and visceral adiposity index (VAI)? VAI could be an easy and useful tool in clinical practice and in population studies for assessment of MU-PCOS. VAI is a good indicator of insulin sensitivity and cardiometabolic risk in oligo-ovulatory women with PCOS. We conducted a cross-sectional study of 232 women with PCOS in a university hospital setting. Anthropometric, hormonal and metabolic parameters were evaluated. An oral glucose tolerance test measured areas under the curve (AUC) for insulin (AUC 2h insulin) and for glucose (AUC 2h glucose). Homeostasis model assessment of insulin resistance (HOMA2-IR), the Matsuda index of insulin sensitivity (ISI), the oral dispositional index (DIo) and VAI were determined. The prevalence of MU-PCOS according to the different criteria was: BMI, 56.0%; WHR, 18.1%; at-risk criteria of AES, 72.0% and VAI, 34.5%. The likelihood that a woman would exhibit MU-PCOS (except when diagnosed by the WHR criterion) showed a significant positive association with high HOMA2-IR [BMI criterion: (odds ratio (OR): 1.86; 95% confidence interval (CI): 1.43-2.41); risk criteria of AES (OR: 1.86; 95% CI: 1.36-2.56); VAI criterion (OR: 1.45; 95% CI: 1.17-1.80)] and a significant negative association with low ISI Matsuda [BMI criterion: (OR: 0.81; 95% CI: 0.72-0.91); risk criteria of AES (OR: 0.78; 95% CI: 0.69-0.89); VAI criterion (OR: 0.82; 95% CI: 0.71-0.94)]. Only MU-PCOS according to the VAI criterion showed a significant association with low DIo (OR: 0.85; 95% CI: 0.75-0.96); these women also showed a significant association with low luteal progesterone levels (OR: 0.97; 95% CI: 0.95-0.99). The analysis is limited by the lack of a gold standard definition of metabolic health that

To estimate rates of ovarian aging in polycystic ovary syndrome (PCOS) subjects versus a community control population. Longitudinal. Tertiary academic center. PCOS subjects diagnosed according to the 2004 Rotterdam criteria were systematically enrolled in a PCOS cohort study. The comparison control subjects were from the Ovarian Aging study, a prospective longitudinal study of ovarian aging in healthy women with regular menstrual cycles. Clinical data collection over two study visits. Antral follicle count (AFC), ovarian volume (OV), and antimüllerian hormone level (AMH). PCOS subjects were found to have higher baseline values for all ovarian reserve markers compared with control subjects. Univariate models indicated that, compared with control subjects, PCOS patients experienced significantly faster rates of decline for both AFC and AMH. Change in OV did not differ significantly. To account for potential confounder effects, multiple analysis of covariance models were evaluated for the best fit, considering age, body mass index, and baseline ovarian reserve markers. Adjusted models demonstrated that PCOS patients do not experience a significant difference in AFC decline compared with control subjects, but they do experience a faster rate of decline in AMH (P<.01) and slower rate of decline in OV (P<.01). Ovarian aging in PCOS is characterized by a more rapid decline in AMH and a slower decline in OV compared with control subjects. Copyright © 2017 American Society for Reproductive Medicine.

Few studies have assessed whether the amelioration of the clinical signs of polycystic ovary syndrome (PCOS) achieved by treatment leads to improvement in the health-related quality of life (HRQoL) of patients. This study was aimed to examine the HRQoL of ethnic Chinese women with PCOS who received metformin treatment. This prospective study was conducted at a medical center in Taiwan. Study participants aged 18-45 years were diagnosed as having PCOS according to the Rotterdam criteria, and all received metformin treatment. Their HRQoL was assessed using generic (WHOQOL-Bref) and PCOS-specific (Chi-PCOSQ) instruments. Mixed effect models were used to examine the effects of metformin on repeatedly measured HRQoL. Additional analyses using stratified patients characteristics (overweight vs. normal; hyperandrogenism vs. non-hyperandrogenism) were done. We recruited 109 participants (56 % were overweight, 80 % had hyperandrogenism). Among the domain scores of WHOQOL-Bref, the psychological domain score was the lowest one (12.64 ± 2.2, range 4-20). Weight (3.25 ± 1.59, range 1-7) and infertility (3.38 ± 1.93, range 1-7) domain scores were relatively low among the domain scores of Chi-PCOSQ. Overweight and hyperandrogenic patients had significantly lower HRQoL as compared with those of normal weight and non-hyperandrogenic patients, respectively. Metformin significantly improved the physical domain of WHOQOL-Bref (p = 0.01), and the infertility (p = 0.043) and acne and hair loss aspects (p = 0.008) of PCOS-specific HRQoL. In the subgroup analysis, significantly improved HRQoL following metformin treatment appeared for only overweight and hyperandrogenism subgroups. Metformin might improve health-related quality of life of polycystic ovary syndrome women by ameliorating psychological disturbances due to acne, hair loss and infertility problems, especially for overweight and hyperandrogenic patients.

To use the Androgen Excess-PCOS Society (AE-PCOS) criteria in adolescents to diagnose polycystic ovary syndrome (PCOS) and identify the prevalence of metabolic risk factors. Retrospective chart review of adolescents (>2 years postmenarche) presenting at a specialty clinic from 2008 through 2010 with complete evaluation for PCOS and metabolic risk were reviewed. Metabolic risk in adolescents with PCOS was compared with those with ≤ 1 AE-PCOS criteria. Of the 205 adolescents evaluated, 66% were found to have PCOS based on the AE-PCOS criteria. The most common presenting symptom was menstrual irregularity, followed by acne, hirsutism, and weight gain. Adolescents with PCOS had a significantly higher prevalence of obesity, hypertension, and low level of high-density lipoprotein cholesterol. Subjects with PCOS had ≥ 1 metabolic risk factor compared with the subjects without PCOS (63.6% vs 33.3%, P = .002). More adolescents with PCOS had ≥ 2 abnormal metabolic risk factors excluding body mass index compared with those without PCOS (P < .02). The prevalence of metabolic syndrome (≥ 3 risk factors) was 10.8% in adolescents with PCOS compared with 1.7% in those without PCOS (P < .04). Adolescents diagnosed with PCOS based on the AE-PCOS criteria are at a significantly increased risk of ≥ 1 metabolic abnormality. Our data underscore the need to accurately diagnose PCOS in the adolescent population instead of delaying the diagnosis to adulthood. Further, using similar criteria for the diagnosis of PCOS in adolescents (>2 years postmenarche) and adults will be more convenient for the clinician. Copyright © 2013 Mosby, Inc.

Polycystic ovary syndrome (PCOS) is one of the most common reproductive endocrine disorders among women of reproductive age, with a variety of complications and consequences mostly due to hyperandrogenism and insulin resistance (IR). PCOS patients with IR are at risk for metabolic syndrome and diabetes mellitus (DM) along with its complications such as cardiovascular events. There are several methods for screening IR in patients with PCOS to predict DM and other complications. Fasting plasma glucose test, oral glucose tolerance test, and insulin and glycosylated hemoglobin (HbA1c) levels are some available screening tools for IR. The American Diabetes Association recommended HbA1c to screen for DM because HbA1c is not affected by day-to-day plasma glucose levels and reflects the plasma glucose status during 2-3 months before measurement. Some studies have evaluated the role of HbA1c as a screening method to predict DM in PCOS patients, however, there are still controversies in this matter. Also some studies reported that HbA1c has a correlation with complications of PCOS such as metabolic syndrome and cardiovascular events. We found that HbA1c could be a suitable screening test for IR in PCOS patients but more studies are recommended, omitting confounding factors that could affect IR in patients with PCOS, such as antihyperglycemic agents like metformin, or lifestyle modification, which can be effective in reducing IR in patients with PCOS.

The phenotype of women with polycystic ovary syndrome (PCOS) is variable, depending on the ethnic background. The phenotypes of women with PCOS in Iceland and Boston were compared. The study was observational with a parallel design. Subjects were studied in an outpatient setting. Women, aged 18-45 yr, with PCOS defined by hyperandrogenism and fewer than nine menses per year, were examined in Iceland (n = 105) and Boston (n = 262). PCOS subjects underwent a physical exam, fasting blood samples for androgens, gonadotropins, metabolic parameters, and a transvaginal ultrasound. The phenotype of women with PCOS was compared between Caucasian women in Iceland and Boston and among Caucasian, African-American, Hispanic, and Asian women in Boston. Androstenedione (4.0 +/- 1.3 vs. 3.5 +/- 1.2 ng/ml; P < 0.01) was higher and testosterone (54.0 +/- 25.7 vs. 66.2 +/- 35.6 ng/dl; P < 0.01), LH (23.1 +/- 15.8 vs. 27.6 +/- 16.2 IU/liter; P < 0.05), and Ferriman Gallwey score were lower (7.1 +/- 6.0 vs. 15.4 +/- 8.5; P < 0.001) in Caucasian Icelandic compared with Boston women with PCOS. There were no differences in fasting blood glucose, insulin, or homeostasis model assessment in body mass index-matched Caucasian subjects from Iceland or Boston or in different ethnic groups in Boston. Polycystic ovary morphology was demonstrated in 93-100% of women with PCOS in all ethnic groups. The data demonstrate differences in the reproductive features of PCOS without differences in glucose and insulin in body mass index-matched populations. These studies also suggest that measuring androstenedione is important for the documentation of hyperandrogenism in Icelandic women. Finally, polycystic ovary morphology by ultrasound is an almost universal finding in women with PCOS as defined by hyperandrogenism and irregular menses.

Polycystic Ovary Syndrome (PCOS) is a common cause of female infertility and first line treatment is currently oral clomiphene citrate, a selective estrogen receptor modulator, which results in both a high nonresponse rate and multiple pregnancy rate. Aromatase inhibitors such as letrozole may have more favorable ovarian and endometrial effects. The goal of the Pregnancy in Polycystic Ovary Syndrome II (PPCOSII) study is to determine the safety and efficacy of clomiphene citrate (CC) compared to letrozole, in achieving live birth in infertile women with PCOS. The population will consist of 750 infertile women with PCOS. Additionally, the couple will have no other major infertility factor. This will be a multi-center, prospective, double-blind clinical trial of CC vs. letrozole for 5 treatment cycles (or approximately up to 25 weeks). The randomization scheme will be coordinated through the central data coordinating center (DCC) and the randomization is stratified by each participating site. After progestin withdrawal as needed, 750 women will be equally randomized to two different treatment arms: A) CC 50mg every day for 5 days (days 3-7 of cycle), or B) letrozole 2.5mg every day for 5 days (days 3-7 of cycle), for a total of 5 cycles or 25 weeks. The dose will be increased in subsequent cycles in both treatment groups for non-response or poor ovulatory response up to a maximum of 150 mg of CC a day (×5 days) or 7.5mg of letrozole a day (×5 days). The primary analysis will use an intent-to-treat approach to examine differences in the live birth rate in the two treatment arms. Copyright © 2012 Elsevier Inc. All rights reserved.

Women with polycystic ovary syndrome (PCOS) experience symptoms such as irregular menses, hirsutism, and acne, and are at heightened risk for developing obesity, metabolic syndrome, diabetes mellitus, infertility, and some cancers. Data also indicate an inverse correlation between PCOS and health-related quality-of-life indicators and self-image. The purpose of this study was to describe the lived experience of women with PCOS in the management of their disorder and the meaning of that experience for them. This qualitative study was conducted using a phenomenological approach based on the guidelines of Van Manen. Individual, semistructured interviews were completed with 10 participants who were diagnosed with PCOS and managed by a health care practitioner(s) within the past 5 years. Data were analyzed using the process of hermeneutic phenomenological reflection. The four major themes that described women's lived experience of managing PCOS were frustration, confusion, searching, and gaining control. Women with PCOS face many challenges in managing their disorder and desire to gain control, balance, and well-being through a comprehensive treatment plan. The findings have implications for health care providers in addressing quality of life issues and overall health outcomes.

Examine the effect of SGTA on AR subcellular localization in granulosa tumor cells (KGN) and SGTA expression in ovarian tissues. University-based research laboratory. Archived tissues from premenopausal women and granulosa cells from infertile women receiving assisted reproduction. None. AR subcellular localization and SGTA protein or mRNA levels. SGTA and AR proteins were expressed in the cytoplasm of KGN cells and exposure to androgen stimulated AR nuclear localization. SGTA protein knockdown increased AR nuclear localization at low (0-0.1 nmol/L) but not high (1-10 nmol/L) concentrations of androgen hormone. In ovarian tissues, SGTA was localized to the cytoplasm of granulosa cells at all stages of folliculogenesis and in thecal cells of antral follicles. SGTA protein levels were similar when comparing primordial and primary follicles within core biopsies (n = 40) from women with and without polycystic ovary syndrome (PCOS). Likewise, SGTA mRNA levels were not significantly different in granulosa cells from preovulatory follicles after hyperstimulation of women with and without PCOS. SGTA is present in human ovaries and has the potential to modulate AR signalling, but it may not be differentially expressed in PCOS. Copyright © 2013 American Society for Reproductive Medicine.

Background Yaks (Bos grunniens) are endemic species that can adapt well to thin air, cold temperatures, and high altitude. These species can survive in harsh plateau environments and are major source of animal production for local residents, being an important breed in the Qinghai–Tibet Plateau. However, compared with ordinary cattle that live in the plains, yaks generally have lower fertility. Investigating the basic physiological molecular features of yak ovary and identifying the biological events underlying the differences between the ovaries of yak and plain cattle is necessary to understand the specificity of yak reproduction. Therefore, RNA-seq technology was applied to analyze transcriptome data comparatively between the yak and plain cattle estrous ovaries. Results After deep sequencing, 3,653,032 clean reads with a total of 4,828,772,880 base pairs were obtained from yak ovary library. Alignment analysis showed that 16992 yak genes mapped to the yak genome, among which, 12,731 and 14,631 genes were assigned to Gene Ontology (GO) categories and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathways. Furthermore, comparison of yak and cattle ovary transcriptome data revealed that 1307 genes were significantly and differentially expressed between the two libraries, wherein 661 genes were upregulated and 646 genes were downregulated in yak ovary. Functional analysis showed that the differentially expressed genes were involved in various Gene Ontology (GO) categories and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathways. GO annotations indicated that the genes related to “cell adhesion,” “hormonal” biological processes, and “calcium ion binding,” “cation transmembrane transport” molecular events were significantly active. KEGG pathway analysis showed that the “complement and coagulation cascade” pathway was the most enriched in yak ovary transcriptome data, followed by the “cytochrome P450” related and �

Chemerin has been linked to adiposity, and insulin resistance (IR) which are the common characteristics of polycystic ovary syndrome (PCOS). Chemerin also shows inhibitory action on follicular steroidogenesis. We investigated the associations between chemerin and IR or polycystic ovary morphology in patients with PCOS. A total of 148 women with newly diagnosed PCOS using Rotterdam criteria and 88 healthy individuals were enrolled. The recruited patients with PCOS were further stratified by tertiles of serum chemerin concentrations as follows: Group 1 (< 24.79 ng/ml), Group 2 (24.79-30.27 ng/ml), and Group 3 (> 30.27 ng/ml). Compared to controls, women with PCOS in each tertile had higher serum chemerin concentrations. By linear regression analysis, homeostasis model assessment-insulin resistance and ovarian volume showed significant associations with chemerin after adjusting for confounding factors (β = 0.257, P = 0.028; β = 0.276, P = 0.005, respectively). The odds ratios (ORs) for ovarian volume excess gradually increased across increasing tertiles of chemerin in the adjusted model [Group 1: reference; Group 2: OR 1.602; 95% confidence interval (CI): 1.170–2.194; Group 3: OR 1.857; 95% CI: 1.335-2.583]. Patients with PCOS showed increased serum chemerin concentrations as compared to healthy women. Individuals with higher chemerin tended to have higher risk for ovarian volume excess in patients with PCOS, regardless of adiposity.

The aim of this study was to assess whether circulating anti-Müllerian hormone (AMH) levels in daughters of women with polycystic ovary syndrome (PCOSd) correspond with clinical and biochemical features of hyperandrogenism, polycystic ovary morphology and menstrual cycle disturbances. Menstrual cycle disturbances, hirsutism, acne and ultrasonographic ovarian morphology were assessed in 75 girls aged 13-18 years (35 PCOSd and 40 daughters of healthy women). Serum gonadotropins, androgens, sex hormone-binding globulin and plasma AMH were measured in a fasting state, and the free androgen index was calculated. A significant correlation between the AMH level and mean ovary volume was found (r = 0.36; p < 0.01). AMH levels were not related to hirsutism, acne and polycystic ovary morphology. Significantly higher AMH levels were found only in PCOSd with irregular menstruation or secondary amenorrhea. The results of logistic regression analysis showed that in that group for each 1-ng/ml increase in the AMH level, the odds ratio of the PCOS occurrence in the future was increased 1.27 times (95% CI: 1.09-1.47; p < 0.01). A higher AMH level in PCOSd is associated with menstrual cycle disturbances and larger ovarian volume but not with clinical and biochemical features of hyperandrogenism. Thus, the risk for PCOS development among genetically predisposed girls may be related to increased AMH levels. © 2016 S. Karger AG, Basel.

Targets to treat androgen excess in polycystic ovary syndrome.

PubMed

Luque-Ramírez, Manuel; Escobar-Morreale, Héctor Francisco

2015-01-01

The polycystic ovary syndrome (PCOS) is a common androgen disorder in reproductive-aged women. Excessive biosynthesis and secretion of androgens by steroidogenic tissues is its central pathogenetic mechanism. The authors review the potential targets and new drugs to treat androgen excess in PCOS. Besides our lab's experience, a systematic search (MEDLINE, Cochrane library, ClinicalTriasl.gov, EU Clinical Trials Register and hand-searching) regarding observational studies, randomized clinical trials, systematic reviews, meta-analyses and patents about this topic was performed. PCOS has a heterogeneous clinical presentation. It is unlikely that a single drug would cover all its possible manifestations. Available treatments for androgen excess are not free of side effects that are of particular concern in these women who suffer from cardiometabolic risk even without treatment. A precise characterization of the source of androgen excess must tailor antiandrogenic management in each woman, avoiding undesirable side effects.

Diagnosis and Management of Polycystic Ovary Syndrome in Adolescent Girls

Polycystic Ovary Syndrome (PCOS) is a common endocrine disorder in adolescent girls having both reproductive and metabolic implications. Patients with PCOS typically present to their pediatrician for evaluation of menstrual irregularity and/or signs of hyperandrogenism, such as hirsutism and acne. The diagnosis of PCOS is made by clinical symptoms and laboratory evaluation. Because of the long-term health consequences that can accompany the disorder, pediatricians should consider PCOS in their initial evaluation of menstrual irregularity. Lifestyle modification is the cornerstone of treatment for girls with PCOS, however hormonal medication such as oral contraceptive pills and insulin sensitizing agents are useful and effective adjuncts to therapy. The goals of treatment for girls with PCOS are to improve clinical manifestations of the disorder, health-related quality of life, and long-term health outcomes. PMID:26431241

Ovulation induction in women with polycystic ovary syndrome: an update.

PubMed

Bhagavath, Balasubramanian; Carson, Sandra A

2012-03-01

Infertility is frequently caused by anovulation. The affected women present with irregular menstrual cycles and the most common diagnosis is polycystic ovary syndrome. Ovulation induction is commonly used to treat these women. Clomiphene citrate (a selective estrogen receptor modulator or SERM) remains the most used medication for treating this condition. Alternatives that have been used include other SERMs such as tamoxifen, aromatase inhibitors, insulin sensitizing agents, and ovarian drilling. Evidence for and against the effectiveness of these agents has fluctuated over the last decade. Controversies surrounding the use of ovulation induction such as development of functional cysts, high-order multiple births, and development of ovarian cancer have been further studied and some controversies have almost been laid to rest in the last decade.

Polycystic ovary syndrome (PCOS), one of the most common endocrine disorders in women of reproductive age, has been associated with the cardiometabolic syndrome and increased risk for cardiovascular diseases. Large (C1) and small (C2) vessel compliance and fasting lipids were measured in 45 healthy women and 36 women with PCOS. There were no differences in vacular compliance (C1, C2) between the 2 groups. Systolic blood pressure (116.8 vs 124.3 mm Hg; P=.01), mean arterial pressure (82.5 vs 87 mm Hg; P=.03), and low-density lipoprotein cholesterol (98.1 vs 119 mg/dL; P=.001) were significantly higher in the PCOS group. This difference was not significant after adjusting for age and body mass index. High-density lipoprotein levels in subjects with PCOS were significantly lower than in healthy women (60.2 vs 48.9 mg/dL, P=.02) even after adjusting for age and body mass index. The study indicates that obesity and low high-density lipoprotein are the major contributing factors to cardiovascular changes in PCOS.

Cardiovascular disease in the polycystic ovary syndrome: new insights and perspectives.

2006-04-01

The new millennium has brought intense focus of interest on the risk of cardiovascular disease in women. The polycystic ovary syndrome (PCOS) is a common endocrine disorder in women characterised by hyperandrogenism and oligomenorrhoea. Most women with PCOS also exhibit features of the metabolic syndrome, including insulin resistance, obesity and dyslipidaemia. While the association with type 2 diabetes is well established, whether the incidence of cardiovascular disease is increased in women with PCOS remains unclear. Echocardiography, imaging of coronary and carotid arteries, and assessments of both endothelial function and arterial stiffness have recently been employed to address this question. These studies have collectively demonstrated both structural and functional abnormalities of the cardiovascular system in PCOS. These alterations, however, appear to be related to the presence of individual cardiovascular risk factors, particularly insulin resistance, rather than to the presence of PCOS and hyperandrogenaemia per se. However, given the inferential nature of the evidence to date, more rigorous cohort studies of long-term cardiovascular outcomes and clinical trials of risk factor modification are required in women with PCOS.

Polycystic ovary syndrome (PCOS) is a complex syndrome showing the clinical features of an endocrine/metabolic disorder, including hyperinsulinemia and hyperandrogenism. Two phenotypes are present, either lean or obese, with different biochemical, hormonal, and metabolic profiles. Evidence suggests many treatment modalities that can be applied. However, many of these modalities were found to be not suitable for the lean phenotype of PCOS. Much contradictory research was found regarding lean patients with PCOS. The aim of this narrative review is to shed light on the debate prevailing regarding characteristics, as well as metabolic, hematological, and potential management modalities. Literature review was performed from January 1, 2000 to March 31, 2017 with specific word search such as lean PCOS, hormonal abnormalities in lean PCOS, and the management of lean PCOS. All retrieved articles were carefully assessed, and data were obtained. We could conclude that the debate is still prevailing regarding this specific lean population with PCOS, especially with regard to their characteristics and management modalities. Further studies are still required to resolve this debate on the presence of PCOS in lean women.

Polycystic ovary syndrome (PCOS) is the most common endocrine disorder among reproductive-aged women and the main cause of infertility due to anovulation. However, this syndrome spans the lives of women affecting them from in-utero life until death, leading to several health risks that can impair quality of life and increase morbidity and mortality rates. Fetal programming may represent the beginning of the condition characterized by hyperandrogenism and insulin resistance which leads to a series of medical consequences in adolescence, adulthood, and old age. Menstrual and fertility problems evolve into metabolic complications as age advances. An early and precise diagnosis is important for an adequate management of PCOS, especially at the extreme ends of the reproductive lifespan. However, many different phenotypes are included under the same condition, being important to look at these different phenotypes separately, as they may require different treatments and have different consequences. In this way, PCOS exhibits a great metabolic complexity and its diagnosis needs to be revised once again and adapted to recent data obtained by new technologies. According to the current medical literature, lifestyle therapy constitutes the first step in the management, especially when excess body weight is associated. Pharmacotherapy is frequently used to treat the most predominant manifestations in each age group, such as irregular menses and hirsutism in adolescence, fertility problems in adulthood, and metabolic problems and risk of cancer in old age. Close surveillance is mandatory in each stage of life to avoid health risks which may also affect the offspring, since fetal and post-natal complications seem to be increased in PCOS women.

Atorvastatin therapy decreases androstenedione and dehydroepiandrosterone sulphate concentrations in patients with polycystic ovary syndrome: randomized controlled study.

Hyperandrogenaemia in polycystic ovary syndrome (PCOS) represents a composite of raised serum concentrations of testosterone, androstenedione, dehydroepiandrosterone (DHEA) and DHEA sulphate (DHEAS). In patients with PCOS, testosterone and androstenedione are primarily derived from the ovaries and DHEAS is a metabolite predominantly from the adrenals. It has been shown that atorvastatin reduces testosterone concentrations in patients with PCOS. The objective was to study the effect of atorvastatin on serum androstenedione and DHEAS concentrations in patients with PCOS. A randomized, double-blind, placebo-controlled study was performed. Forty medication-naive patients with PCOs were randomized to either atorvastatin 20mg daily or placebo for three months. Subsequently, a three-month extension study for all patients was undertaken with metformin 1500 mg daily. The main outcome measures were change in androstenedione and DHEAS concentrations. The mean (SD) baseline androstenedione (5.7 [0.8] versus 5.6 [1.3] nmol/L; P = 0.69) and DHEAS (7.1 [1.0] versus 7.2 [1.2] μmol/L; P = 0.72) concentrations were comparable between two groups. There was a significant reduction of androstenedione (5.7 [0.8] versus 4.7 [0.7] nmol/L; P = 0.03) and DHEAS (7.1 [1.0] versus 6.0 [0.9] μmol/L; P = 0.02) with three months of atorvastatin while there were no significant changes with placebo. Three months' treatment with metformin maintained the reduction of androstenedione and DHEAS concentrations with atorvastatin compared with baseline. There were no changes in either DHEAS or androstenedione concentrations in the initial placebo group after 12 weeks of metformin. Twelve weeks of atorvastatin significantly reduced both DHEAS and androstenedione contributing to the total reduction of androgen concentrations and indicating that the reduction of the hyperandrogenaemia could be partly due to the action of atorvastatin at both the ovary and the adrenal gland in PCOS.

To compare the effects of oral contraceptive pills containing desogestrel, cyproterone acetate, and drospirenone, in polycystic ovary syndrome (PCOS), after 6 and 12 months of therapy. Double-blind randomized controlled trial. Gynecologic clinic of the first author. Women (n = 171) with PCOS (Androgen Excess Society criteria, 2006). The three-arm trial involved 58, 56, and 57 cases in desogestrel, cyproterone acetate, and drospirenone groups, respectively. Body mass index, abdominal circumference, hirsutism score (modified Ferriman Galwey), acne and acanthosis nigricans scores, and blood pressure were noted. Blood levels of total T, sex hormone-binding globulin, fasting glucose, and fasting insulin were measured. Free androgen index, glucose-insulin ratio, and homeostasis model assessment-insulin resistance were calculated. Follow-up was after 6 and 12 months of treatment. Primarily, absolute change in the Free Androgen Index score between the three groups and, secondarily, changes in the clinical and other hormonal and biochemical parameters were studied. Six months of treatment showed similar effects. After 12 months, cyproterone acetate significantly decreased the modified Ferriman Galwey score (change = -5.29) compared with both desogestrel (change = -1.69) and drospirenone (change = -2.12); cyproterone acetate significantly increased sex hormone-binding globulin (change = 142.91) compared with desogestrel (change = 99.53); drospirenone significantly increased sex hormone-binding globulin (change = 131.52) compared with desogestrel; and cyproterone acetate significantly decreased the Free Androgen Index (change = -10.57) compared with desogestrel (change = -5.58). No difference in effects after 6 months. At 12 months, cyproterone acetate showed the strongest antiandrogen activities. Effects on metabolic parameters were identical. CTRI/2010/091/000332.

To compare lipid profile in lean and obese women with polycystic ovary syndrome with normal weight and obese controls. The case-control study was conducted at the Department of Chemical Pathology, Liaquat National Hospital, Karachi, from March 2006 to April 2007. It comprised 50 cases of polycystic ovary syndrome along with 50 healthy controls matching for age, gender and weight. SPSS 14 was used for statistical analysis. The mean fasting levels of triglyceride and Low density lipoprotein cholesterol were considerably higher in women with polycystic ovary syndrome than those in the control group (p < 0.05), while high-density lipoprotein cholesterolwas significantly low in patients than the controls (p <0.001). Obese patients had high triglyceride value (p < 0.05). There was significant interaction between polycystic ovary syndrome, obesity and triglyceride levels (p < 0.05). Polycystic ovary syndrome is associated with a more pronounced atherogenic lipid profile. Lipid parameters were adversely affected in a subgroup that was obese. As such, women with polycystic ovary syndrome are at high risk of developing cardiovascular disease due to the presence of dyslipidaemia.

Since its introduction in 1984, laparoscopic ovarian drilling has evolved into a safe and effective surgical treatment for anovulatory, infertile women with polycystic ovary syndrome (PCOS), unresponsive to clomiphene citrate. It is as effective as gonadotropins in terms of pregnancy and live birth rates, but without the risks of ovarian hyperstimulation syndrome and multiple pregnancies. It improves ovarian responsiveness to successive ovulation induction agents. Its favorable reproductive and endocrinal effects are sustained long. Despite its advantages, its use in unselected cases of PCOS or for non-fertility indications is not prudent owing to the potential risks of iatrogenic adhesions and ovarian insufficiency.

To determine the relationship between urinary albumin excretion and features of the metabolic syndrome in women with polycystic ovary syndrome (PCOS). We retrospectively analyzed the medical records of 189 premenopausal women (mean age +/- SD, 28.9 +/- 7.7 years) with PCOS and 81 control patients (mean age +/- SD, 37.9 +/- 8.6 years) from a single endocrinology practice. Exclusion criteria were diabetes, heart disease, kidney disease, use of lipid-lowering agents, and use of antihypertensive agents (except spironolactone). The urine albumin-to-creatinine ratio (ACR) was measured in a random single-voided urine sample. Premicroalbuminuria was defined as an ACR >7 mg/g. The prevalence of ACR >7 mg/g was 31.2% in the PCOS group (N = 189) and 35.8% in the control group (N = 81). The metabolic syndrome was noted in 16.3% (27 of 166) of patients with PCOS and in 2.9% (2 of 69) of control subjects. Nine percent of patients with PCOS who had an ACR 7 mg/g had the metabolic syndrome. Patients with PCOS who had an ACR >7 mg/g had significantly higher blood pressure and alanine aminotransferase levels than did those with an ACR 7 mg/g, no significant difference was found in frequency of use of metformin, spironolactone, or oral contraceptives. In women with PCOS, an ACR >7 mg/g was strongly associated with the metabolic syndrome, high blood pressure, and elevated alanine aminotransferase levels. It may be useful to consider ACR >7 mg/g as an associated sign of the presence of metabolic syndrome in women with PCOS.

Polycystic Ovary Syndrome: Important Underrecognised Cardiometabolic Risk Factor in Reproductive-Age Women

Polycystic ovary syndrome (PCOS) is the most common endocrine disorder amongst women of reproductive age. Although PCOS is diagnosed exclusively based on reproductive criteria, it is also a metabolic disorder. Insulin resistance, impaired glucose tolerance, type 2 diabetes mellitus, obesity, and dyslipidemia are more common in women with PCOS than in age-comparable women without PCOS. Many of the metabolic abnormalities that manifest in PCOS are worsened by the concurrent incidence of obesity. However, some of these metabolic perturbations occur even in lean women with PCOS and therefore are rightfully recognized as intrinsic to PCOS. The intrinsic factors that produce these metabolic disturbances are reviewed in this paper. The consequences of obesity and the other metabolic aberrations are also discussed. The metabolic perturbations in PCOS patients lead to chronic low-grade inflammation and to cardiovascular impairments that heighten the risk of having cardiovascular disease. Even though many studies have shown an elevation in surrogate biomarkers of cardiovascular disease in PCOS women, it is still not clear to what extent and magnitude the elevation precipitates more frequent and earlier events.

A genetic risk score is associated with polycystic ovary syndrome-related traits.

Is a genetic risk score (GRS) associated with polycystic ovary syndrome (PCOS) and its related clinical features? The GRS calculated by genome-wide association studies (GWASs) was significantly associated with PCOS status and its related clinical features. PCOS is a heterogeneous disorder and is characterized by oligomenorrhea, hyperandrogenism and polycystic ovary morphology. Although recent GWASs have identified multiple genes associated with PCOS, a comprehensive genetic risk study of these loci with PCOS and related traits (e.g. free testosterone, menstruation number/year and ovarian morphology) has not been performed. This study was designed as a cross-sectional case-control study. We recruited 862 women with PCOS and 860 controls. Women with PCOS were divided into four subgroups: (1) oligomenorrhea + hyperandrogenism + polycystic ovary, (2) oligomenorrhea + hyperandrogenism, (3) oligomenorrhea + polycystic ovary and (4) hyperandrogenism + polycystic ovary. Genomic DNA was genotyped for the PCOS susceptibility loci using the HumanOmni1-Quad v1 array. Venous blood was drawn in the early follicular phase to measure baseline metabolic and hormonal parameters. A GRS was calculated by summing the number of risk alleles from 11 single-nucleotide polymorphisms (SNPs) that were identified in previous GWASs on PCOS. A weighted GRS (wGRS) was calculated by multiplying the number of risk alleles for each SNP by its estimated effect (beta) obtained from the association analysis. The GRS was higher in women with PCOS than in controls (8.8 versus 8.2, P < 0.01) and was significantly associated with PCOS after adjusting for age and BMI. An analysis of GRS quartiles (Q1 = 3-5, Q2 = 6-8, Q3 = 9-11, Q4 = 12-15) revealed that the subjects in the highest quartile showed a remarkable increased risk of PCOS compared with those in the lowest quartile (odds ratio = 6.28, P < 0.001).

2016-03-01

This study was designed to assess the value of serum anti-Müllerian hormone (AMH) in the diagnosis of polycystic ovary syndrome (PCOS) in various phenotypes and to assess ovarian ultrasound parameters. We performed a retrospective matched controlled study of 113 females with various PCOS phenotypes and 47 matched controls. The diagnostic utility of AMH measurement and ovarian ultrasound were compared. Using receiver operating characteristic (ROC) curve analyses, the threshold for AMH (>4.7 ng/mL) and ultrasound parameters (follicle number per ovary [FNPO] >22 and ovarian volume [OV] >8 cc) were established. In the entire cohort, AMH had a low sensitivity of 79%; while FNPO and OV were 93% and 68%, respectively. Specificities ranged from 85 to 96%. In classic anovulatory PCOS, AMH exhibited a sensitivity of 91%, and for FNPO and OV the corresponding sensitivities were 92% and 72%. In the ovulatory phenotype, AMH sensitivity was only 50%, while FNPO and OV were 95% and 50%, respectively. In the nonhyperandrogenic phenotype, the sensitivity of AMH was 53% while those for FNPO and OV were 93% and 67%. AMH does not appear to be helpful for all subjects with PCOS but may be of some value in those who are anovulatory. However, FNPO was highly sensitive in all phenotypes, and was the single best criterion assessed for all subjects, suggesting the important role of ultrasound.

To assess the association between polycystic ovary syndrome (PCOS) and cancer, especially of the endometrium, breast and ovary. The Danish National Patient Register was used to identify 12,070 in- and outpatients in whom PCOS was diagnosed when they were aged 9-49 years during 1977-2012. Using the Danish Cancer Registry, we followed the cohort through 2012 and compared the women's cancer incidence with that of the general Danish female population by means of standardized incidence ratios (SIRs). Cancer was diagnosed in 279 women with PCOS (SIR = 1.19; 95% CI = 1.06-1.34). We found an almost fourfold increased risk for endometrial cancer (numbers observed (N) = 16, SIR = 3.9; 95% CI = 2.2-6.3), the large majority of cases being type 1 (N = 14, SIR = 4.7; 95% CI = 2.6-7.9). We found no association between PCOS and breast (N = 59, SIR = 1.1; 95% CI = 0.8-1.4) or ovarian cancer (N = 10, SIR = 1.8; 95% CI = 0.8-3.2); however, significantly increased risks were found for kidney, colon and brain cancers. The results of this large cohort study support those of case-control studies showing that women with PCOS are at increased risk for endometrial cancer, whereas their risks for breast and ovarian cancer are similar to those of women in the general population. Our finding that women with PCOS also are at increased risk for cancers of the kidney, colon and brain requires further study. Copyright © 2014 Elsevier Inc. All rights reserved.

The diagnosis of polycystic ovary syndrome (PCOS) is based on a combination of various clinical phenotypes in each patient. However, insulin resistance (IR) and dysmetabolism are not included in the diagnostic criteria of PCOS. Therefore, the definition of PCOS is controversial. The objective of this study is to investigate whether some PCOS phenotypes can be predicted by a circulating biomarker related to IR and metabolic dysfunction in PCOS women. One hundred and seventeen women with PCOS and 95 healthy women were recruited for this study. All individuals were assessed by the phenotypic and metabolic characteristics related to PCOS. A euglycemic-hyperinsulinemic clamp was performed to assess insulin sensitivity. Circulating irisin concentrations were determined with ELISA. In our PCOS cohort, 65.8% of individuals were found to have hyperandrogenism. 83.8% had chronic oligoanovulation, and 80.3% of subjects showed polycystic ovaries. According to the diagnostic criteria of PCOS, 30.8% of PCOS subjects were diagnosed with the classic phenotype. In addition, 65.8% of PCOS women had insulin resistance. Serum irisin levels were significantly higher in PCOS women compared with healthy women. However, PCOS women with a normoandrogenic phenotype had similar circulating irisin levels as healthy women. PCOS women with the normoandrogenic phenotype had a low homeostasis model assessment of insulin resistance (HOMA-IR) and higher M-values than PCOS women with other phenotypes. Circulating irisin levels were associated with hyperandrogenism, but not with oligoanovulation or PCO morphology. Circulating irisin may allow physicians to establish which women merit screening by a biomarker for PCOS.

Polycystic ovary syndrome in adolescence.

Polycystic ovary syndrome (PCOS) is a common disorder among reproductive-age women, yet the diagnosis may be overlooked during adolescence. Although the clinical and metabolic features are similar to those found in adult women, it can be difficult to distinguish the young woman with PCOS from a normal adolescent. Irregular menses, anovulatory cycles, and acne are not uncommon in adolescent women. Adolescents with a history of premature pubarche, a family history of PCOS, Caribbean-Hispanic and African-American ancestry, and/or obesity are at risk for PCOS and deserve close surveillance. The laboratory evaluation of the adolescent with suspected PCOS or hyperandrogenism should be individualized based on the history, symptoms, and examination findings. The cornerstone of management of PCOS in adolescence includes either a combination oral contraceptive or progestin. Consideration of insulin-sensitizing agents, antiandrogens, topical treatments for acne, and various treatments for hair removal are dependent on the patient's symptoms and concerns. Healthy eating, regular exercise, and for the overweight adolescent, weight reduction, are encouraged to reduce the risk of cardiovascular disease and type II diabetes mellitus. Numerous studies have shown that weight loss and exercise decrease androgen levels, improve insulin sensitivity, and lead to the resumption of ovulation. Although initial studies suggest that Metformin may be particularly useful for treating the PCOS adolescent with insulin resistance and obesity, additional studies are needed to determine the efficacy and long-term outcome. Management of the adolescent with PCOS is challenging and requires a supportive, multidisciplinary team approach for optimal results.

Our specific aim was to determine whether coronary heart disease (CHD) risk factors in polycystic ovary syndrome (PCOS) patients were independent of their higher body mass index (BMI) and centripetal obesity. In adult, premenopausal, white women, CHD risk factors were compared between 488 patients with well-defined PCOS and 351 healthy free-living population controls from the Princeton Follow-up Study (PFS). After excluding women with irregular menses (putative PCOS phenotypes), comparisons were also made between the 261 PFS women with a history of regular menses and the 488 women with PCOS. Fasting lipids, insulin, glucose, homeostasis model assessment of insulin resistance (HOMA-IR), HOMA insulin secretion, blood pressure, BMI, and waist circumference were measured. Compared with both the full cohort of 351 PFS women and the subgroup of 261 PFS women with regular menses, women with PCOS had higher BMI, waist circumference, total and low-density lipoprotein cholesterol, triglyceride, systolic blood pressure, diastolic blood pressure, insulin, glucose, and HOMA-IR (all Ps < or = .005). After adjusting for age and BMI, women with PCOS, compared with the 351 and 261 PFS women, had lower high-density lipoprotein cholesterol (P < .0001, .0008) and higher systolic blood pressure (P = .0002, < .0001), insulin (P = .017, .039), HOMA-IR (P = .013, .032), and HOMA insulin secretion (P = .022, .037). The small subgroup of PCOS women with normal BMI (<25 kg/m(2)) (36/488, 7%) also had higher age-adjusted insulin, glucose, and HOMA-IR (all Ps < .005) than the subgroup of PFS women with BMI less than 25 kg/m(2) (123/261, 47%). Increased CHD risk factors and high HOMA-IR in PCOS cannot be exclusively attributed to their preponderant centripetal obesity. Identification of women with clinical features of PCOS should alert the clinician to potentially increased risk for CHD and prompt CHD risk factor testing.

We aimed to compare a combined oral contraceptive (COC) plus the antiandrogen spironolactone with the insulin sensitizer metformin in women with polycystic ovary syndrome (PCOS). We conducted a randomized, parallel, open-label, clinical trial comparing COC (30 μg of ethinylestradiol and 150 μg of desogestrel) plus spironolactone (100 mg/day) with metformin (850 mg b.i.d.) for one year in women with PCOS (EudraCT2008-004531-38). The composite primary outcome included efficacy (amelioration of hirsutism, androgen excess and menstrual dysfunction) and cardiometabolic safety (changes in the frequencies of disorders of glucose tolerance, dyslipidemia and hypertension). A complete anthropometric, biochemical, hormonal and metabolic evaluation was conducted every three months and data were submitted to intention-to-treat analyses. Twenty-four patients were assigned to COC plus spironolactone and 22 patients to metformin. Compared with metformin, COC plus spironolactone caused larger decreases in hirsutism score (mean difference 4.6 points, 95% CI: 2.6-6.7), total testosterone (1.1 nmol/L, 0.4-1.7), free testosterone (25 pmol/L, 12-39), androstenedione (5.5 nmol/L, 1.8-9.2) and dehydroepiandrosterone sulfate (2.7 μmol/L, 1.4-4.0). Menstrual dysfunction was less frequent with COC plus spironolactone (OR: 0.06, 95% CI: 0.02-0.23). No differences were found in frequencies of abnormal glucose tolerance (OR: 1.7, 95% CI: 0.7-4.4), dyslipidemia (OR: 0.6, 95% CI: 0.2-1.8) or hypertension (OR: 0.3, 95% CI: 0.5-2.0). No major adverse events occurred and biochemical markers were similarly safe with both treatments. COC plus spironolactone was more effective than metformin for symptoms of PCOS showing similar safety and overall neutral effects on cardiometabolic risk factors. © 2017 European Society of Endocrinology.

Background/aim: Various studies have shown that adult patients with polycystic ovary syndrome (PCOS) have higher levels of anxiety and depression compared to their normal counterparts. However, it is still unclear whether these mood disorders already exist in adolescents affected by PCOS. The aim of the present study is to assess differences in anxiety and depression levels between adolescents with PCOS and age- and body mass index (BMI)-matched controls and to determine the possible factor(s) impacting these psychological parameters in adolescents with PCOS. Materials and methods: The study included 80 adolescents with PCOS and 50 age- and BMI-matched controls. All participants completed standardized questionnaires assessing anxiety and depression. A multiple linear regression model was used to analyze the impact of potential variables on anxiety and depression scores of the adolescents with PCOS. Results: Significantly higher levels of anxiety, specifically generalized and social anxieties, as well as depression were found in adolescents with PCOS compared to controls. Higher BMI was found to be associated with higher levels of depression and generalized anxiety, and higher modified Ferriman-Gallwey score with higher level of panic disorder in adolescents affected by PCOS. Conclusion: Adolescents with PCOS experience significantly more emotional distress compared to adolescents without PCOS. This emotional distress may be related, at least in part, to certain clinical features of PCOS including obesity and hirsutism. PCOS in adolescents should be assessed not only for the gynecological and metabolic aspects but also for the emotional aspects of the disease.

Skin improvement with two different oestroprogestins in patients affected by acne and polycystic ovary syndrome: clinical and instrumental evaluation.

Despite it is accepted that acne is mostly caused by an hyper-responsiveness of the pilo-sebaceous unit to normal circulating androgen hormones, in a few patients, especially women, acneic lesions can be associated with increased serum androgen levels (hyperandrogenism), of which polycystic ovary syndrome (PCOS) is the most common cause. In women with acne and proven PCOS therapy with estroprogestins (EPs) can be an excellent option. The aim of the study was to assess the effects of two estroprogestins (EPs), ethinyl-estradiol (EE) 30 mcg/drospirenone (DRSP) 3 mg, and ethinyl-estradiol (EE) 30 mcg/chlormadinone acetate (CMA) 2 mg, both on increased serum androgen levels and on several skin parameters in women affected by mild to severe acne and polycystic ovary syndrome (PCOS). Fifty-nine women were randomized to receive EE/DRSP (n = 32) or EE/CMA (n = 27) for six months. Evaluation of serum androgen levels, grading of acne and hirsutism (respectively with Pillsbury and Ferriman-Gallwey score) and non-invasive assessment of skin hydration, transepidermal water loss (TEWL) and skin homogeneity were performed at baseline, at 3 and 6 months (end of treatment). Both treatments were well tolerated and showed a significant improvement of skin and hormonal parameters, although EE/DRSP showed a more potent effect on acne and seborrhea. Estroprogestins represent an effective and safe treatment in women with acne and polycystic ovary syndrome (PCOS). Nevertheless, the combination EE 30 mcg/DRSP 3 mg appears to be a more potent therapeutic option. © 2011 The Authors.

Polycystic ovary syndrome (PCOS) is a common, heterogeneous disorder characterised by hyperandrogenic skin symptoms, irregular menstruation and subfertility, increased risk of endometrial malignancy, and increased risk of preventable diseases associated with metabolic syndrome. Cyproterone acetate (CPA) 2 mg, combined with ethinylestradiol (EE) 35 μg, is indicated for the treatment of moderate to severe acne related to androgen-sensitivity (with or without seborrhea) and/or hirsutism, in women of reproductive age. To review the present knowledge about PCOS and summarize the role of CPA/EE in the care of patients suffering from this condition for the practitioner. Experts with clinical interest and experience in treating symptoms of androgen excess performed a non-systematic review to provide updated information regarding the use of CPA/EE in patients with PCOS. Polycystic ovary-related hyperandrogenic skin symptoms are effectively treated by CPA/EE, reducing not only the symptoms but also their negative impact on quality of life and mental health. Proven additional benefits for these patients include the treatment of menstrual irregularities and reduction in endometrial cancer risk. Possible benefits include preservation of fertility. Treatment increases the risk for venous thromboembolic complications. The nature of other metabolic and cardiovascular long-term effects i.e., whether positive or negative, are still to be investigated. Cyproterone acetate/ethinylestradiol provides effective treatment for PCO-related hyperandrogenic skin symptoms. This efficacy and additional benefits related to menstrual irregularities and endometrial cancer risk, have to be weighed against the risk of venous thromboembolic complications based on an individual benefit/risk evaluation.

Adiposity and metabolic dysfunction in polycystic ovary syndrome.

PubMed

Sam, Susan

2015-02-01

Polycystic ovary syndrome (PCOS) is the most common hormonal disorder among reproductive-age women and is associated with a high risk for metabolic disorders. Adiposity and insulin resistance are two prevalent conditions in PCOS and the likely culprits for the heightened metabolic risk. Up to 60% of women with PCOS are considered to be overweight or obese, and even among non-obese women with PCOS there is an increased accumulation of adipose tissue in abdominal depots. Insulin resistance in PCOS is unique and independent of obesity, as even non-obese women with this condition are frequently insulin resistant. However, obesity substantially aggravates the insulin resistance and the metabolic and reproductive abnormalities in women with PCOS. Recently, it has been shown that many aspects of adipose tissue function in PCOS are abnormal, and these abnormalities likely predispose to development of insulin resistance even in the absence of obesity. This review provides an overview of these abnormalities and their impact on development of metabolic disorders. At the end, an overview of the therapeutic options for management of adiposity and its complications in PCOS are discussed.

Polycystic ovary syndrome (PCOS) affects 12-21% of women. Women with PCOS exhibit clustering of metabolic features. We applied rigorous statistical methods to further understand the interplay between PCOS and metabolic features including insulin resistance, obesity and androgen status. Retrospective cross-sectional analysis. Women with PCOS attending reproductive endocrine clinics in South Australia for the treatment of PCOS (n = 172). Women without PCOS (controls) in the same Australian region (n = 335) from the Australian Diabetes, Obesity and Lifestyle Study (AusDiab), a national population-based study (age- and BMI-matched within one standard deviation of the PCOS cohort). The factor structure for metabolic syndrome for women with PCOS and control groups was examined, specifically, the contribution of individual factors to metabolic syndrome and the association of hyperandrogenism with other metabolic factors. Women with PCOS demonstrated clustering of metabolic features that was not observed in the control group. Metabolic syndrome in the PCOS cohort was strongly represented by obesity (standardized factor loading = 0·95, P < 0·001) and insulin resistance factors (loading = 0·92, P < 0·001) and moderately by blood pressure (loading = 0·62, P < 0·001) and lipid factors (loading = 0·67, P = 0·002). On further analysis, the insulin resistance factor strongly correlated with the obesity (r = 0·70, P < 0·001) and lipid factors (r = 0·68, P < 0·001) and moderately with the blood pressure factor (loading = 0·43, P = 0·002). The hyperandrogenism factor was moderately correlated with the insulin resistance factor (r = 0·38, P < 0·003), but did not correlate with any other metabolic factors. PCOS women are more likely to display metabolic clustering in comparison with age- and BMI-matched control women. Obesity and insulin resistance, but not androgens, are independently and most strongly associated with metabolic syndrome in PCOS. © 2015 John Wiley

The objective of the study was to compare the effects of essential vs long-chain omega (n)-3 polyunsaturated fatty acids (PUFAs) in polycystic ovary syndrome. In this 6-week, prospective, double-blinded, placebo (soybean oil)-controlled study, 51 completers received 3.5 g n-3 PUFA per day (essential PUFA from flaxseed oil or long-chain PUFA from fish oil). Anthropometric variables, cardiovascular risk factors, and androgens were measured; oral glucose tolerance test (OGTT) and frequently sampled intravenous GTT (IVGTT) were conducted at baseline and 6 weeks. Between-group comparisons showed significant differences in serum triglyceride response (P = .0368), whereas the changes in disposition index also tended to differ (P = .0621). When within-group changes (after vs before intervention) were considered, fish oil and flaxseed oil lowered serum triglyceride (P = .0154 and P = .0176, respectively). Fish oil increased glucose at 120 minutes of OGTT (P = .0355), decreased the Matsuda index (P = .0378), and tended to decrease acute insulin response during IVGTT (P = .0871). Soybean oil increased glucose at 30 (P = .0030) and 60 minutes (P = .0121) and AUC for glucose (P = .0122) during OGTT, tended to decrease acute insulin response during IVGTT (P = .0848), reduced testosterone (P = .0216), and tended to reduce sex hormone-binding globulin (P = .0858). Fasting glucose, insulin, adiponectin, leptin, or high-sensitivity C-reactive protein did not change with any intervention. Long-chain vs essential n-3 PUFA-rich oils have distinct metabolic and endocrine effects in polycystic ovary syndrome; and therefore, they should not be used interchangeably.

In-vitro maturation (IVM) treatment has gained popularity for decreasing the incidence of ovarian hyperstimulation syndrome (OHSS) by eliminating or minimizing the use of gonadotrophins in women with polycystic ovary syndrome (PCOS). Studies have shown that IVF with GnRH-antagonist protocol is associated with a lower incidence of OHSS. Data comparing the relative success of these two treatments is, however, lacking. Treatment outcome and rates of OHSS were compared in patients with PCOS who underwent assisted conception with either IVM or IVF with GnRH-antagonist protocol between 2006 and 2011. The number of oocytes retrieved was higher in the IVM group, whereas the number of mature oocytes, fertilization rate and number of embryos cleaved were comparable. The implantation rate was higher in the IVF group. The clinical pregnancy rates per embryo transfer were not statistically different (IVF: 45.8% versus IVM: 32.4%). The live-birth rate was higher in the IVF group (IVF: 40.7% versus IVM: 23.5%; P = 0.04). Five women developed moderate or severe OHSS in the IVF group, whereas none did in the IVM group. Both IVM and IVF with GnRH-antagonist protocol seem to be effective treatment regimens in women with PCOS, although IVM is associated with a lower risk of OHSS.

Previous studies have indicated that berberine is an effective insulin sensitizer with comparable activity to metformin (Diabetes 2006, 55, 2256). Reduced insulin sensitivity is reportedly a factor adversely affecting the outcome of IVF in patients with polycystic ovary syndrome (PCOS) (Human Reproduction 2006, 21, 1416). Our objective was to evaluate the clinical, metabolic and endocrine effects of berberine vs metformin in PCOS women scheduled for IVF treatment and to explore the potential benefits to the IVF process. We performed a prospective study in 150 infertile women with PCOS undergoing IVF treatment. Patients were randomized to receive berberine, metformin or placebo tablets for 3 months before ovarian stimulation. The clinical, endocrine, metabolic parameters and the outcome of IVF. Compared with placebo, greater reductions in total testosterone, free androgen index, fasting glucose, fasting insulin and HOMA-IR, and increases in SHBG, were observed in the berberine and metformin groups. Three months of treatment with berberine or metformin before the IVF cycle increased the pregnancy rate and reduced the incidence of severe ovarian hyperstimulation syndrome. Furthermore, treatment with berberine, in comparison with metformin, was associated with decreases in BMI, lipid parameters and total FSH requirement, and an increase in live birth rate with fewer gastrointestinal adverse events. Berberine and metformin treatments prior to IVF improved the pregnancy outcome by normalizing the clinical, endocrine and metabolic parameters in PCOS women. Berberine has a more pronounced therapeutic effect and achieved more live births with fewer side effects than metformin. © 2013 John Wiley & Sons Ltd.

To observe the effect of Cangfu Congxian Decoction (CCD) on oxidative stress in granulosa cells of polycystic ovary syndrome (PCOS) patients. Forty PCOS patients underwent in vitro fertilization-embryo transfer (IVF-ET) were assigned to the treatment group and the control group 1 according to random digit table, 20 in each group. Patients in the treatment group took CCD (200 mL, once in the morning and once in the afternoon) 2 months before IVF-ET, while those in the control group 1 took no Chinese medical decoction. Recruited were another 20 patients undergoing IVF-ET for tubal factors (as the control group 2). The clinical effect of IVF-ET were observed, including oocyte retrieval number, 2 pronuclear (2PN) fertilization rate, good quality embryo rate, clinical pregnancy rate, and ovarian hyperstimulation syndrome (OHSS) induced transplantation cancel rate. The expression of relative oxygen species (ROS) in granulosa cells was detected using cell immunofluorescence combined with confocal microscopy and FCM. Compared with the control group 1, occyte retrieval number, 2PN fertilization rate, and good quality embryo rate increased in the control group 2 and the treatment group (P <0. 05). OHSS induced transplantation cancel rate decreased in the control group 2 (P < 0.05). Fluorescence intensity of ROS decreased in the treatment group and the control group 2, as compared with the control group 1 (P < 0.01). CCD increased good quality embryo rate by down-regulating the expression of ROS protein in ovarian granulosa cells, and correcting in vivo oxidative stress.

Polycystic ovary syndrome and risk of endometrial, ovarian, and breast cancer: a systematic review.

Polycystic ovary syndrome (PCOS) is a complex endocrine disorder with an estimated prevalence of 4-21% in reproductive aged women. The altered metabolic and hormonal environment among women with PCOS may increase their risk of some types of cancer. We performed a comprehensive review of the literature using numerous search terms for all studies examining the associations between polycystic ovary syndrome and related characteristics and cancer published in English through October 2016. This review summarizes the epidemiological findings on the associations between PCOS and endometrial, ovarian, and breast cancers and discusses the methodological issues, complexities, and underlying mechanisms of these associations. We identified 11 individual studies and 3 meta-analyses on the associations between PCOS and endometrial cancer, 8 studies and 1 meta-analysis for ovarian cancer, and 10 studies and 1 meta-analysis for breast cancer. Multiple studies reported that women with PCOS were at a higher risk for endometrial cancer; however, many did not take into account body mass index (BMI), a strong and well-established risk factor for endometrial cancer. The association with ovarian cancer was less clear, but a potentially increased risk of the borderline serous subtype was reported by two studies. No consistent association between PCOS risk and breast cancer was observed. The associations between PCOS and endometrial, ovarian, and breast cancer are complex, with the need to consider many methodological issues in future analyses. Larger well-designed studies, or pooled analyses, may help clarify these complex associations.

Limited data suggest that menstrual cycle abnormalities are more pronounced in younger and more obese patients with polycystic ovary syndrome (PCOS). We aimed to evaluate the association between menstrual cycle pattern and age, obesity and PCOS phenotype in a large population of women with PCOS. We studied 1,297 women with PCOS and divided them according to: a) age in ≤ 20, 21-30 and > 30 years old, b) body mass index in normal weight, overweight and obese and c) PCOS phenotype in phenotype 1 (anovulation, hyperandrogenemia and polycystic ovaries), 2 (anovulation and hyperandrogenemia without polycystic ovaries), 3 (hyperandrogenemia and polycystic ovaries without anovulation) and 4 (anovulation and polycystic ovaries without hyperandrogenemia). The proportion of women with regular menstrual cycles progressively increased in the older age groups, being 8.1, 10.5 and 12.7% in women ≤ 20, 21-30 and > 30 years old, respectively (p = 0.037). The proportion of women with regular menstrual cycles did not differ between normal weight and obese women but was higher in overweight women (9.3, 9.4 and 13%, respectively; p = 0.020). The proportion of women with regular cycles alternating with irregular cycles was highest in women with phenotype 4, intermediate in women with phenotype 2 and lowest in women with phenotype 1 (74.3, 69.4 and 61.7%, respectively; p = 0.027). Menstrual cycle pattern is more irregular in women with the "classic" PCOS phenotypes than in phenotype 4 but appears to normalize with ageing. On the other hand, obesity does not appear to have an important effect on menstrual cycle pattern in PCOS.

Polycystic ovary syndrome and insulin: our understanding in the past, present and future.

Insulin resistance is prevalent in women with polycystic ovary syndrome (PCOS), and plays a critical pathophysiologic role in both the metabolic and reproductive complications of PCOS. This review focuses on the contribution of insulin resistance to anovulation in PCOS and to the high risk for Type 2 diabetes, metabolic syndrome and early cardiovasular disease. Key points for clinicians emphasized by this review are the following: PCOS is a clinical diagnosis and alternative diagnoses must be excluded; PCOS carries an inherent risk of insulin resistance and, hence, metabolic consequences for which women with PCOS should be screened regardless of BMI or degree of obesity; and PCOS is associated with infertility and this should be discussed early on in care of women diagnosed with PCOS, recognizing that there are several possible strategies to address infertility in women with PCOS, each with its own risks and benefits.

Polycystic ovary syndrome (PCOS) is associated with significant risk factors for cardiovascular disease (CVD) like insulin resistance, hyperinsulinism, hypertension and dyslipidemia. We studied CVD risk in young women (18-35 years age) with PCOS using carotid intima media thickness (CIMT) and brachial artery flow mediated dilation (FMD) which are markers of subclinical atherosclerosis. Fifty women with PCOS (age: 24.3 ± 4 years; body mass index [BMI]: 24.6 ± 4 kg/m(2)) were compared with 50 age and BMI matched healthy controls (age: 24.6 ± 5 years; BMI: 23.9 ± 4 kg/m(2)). CIMT was significantly higher (0.55 ± 0.09 mm versus 0.40 ± 0.1 mm, p value <0.0001) and FMD was significantly lower (9.39 ± 4.36% versus 13.89 ± 4.77%, p value <0.0001) in cases as compared to controls. These differences in CIMT and FMD remained significant when subgroup were analyzed, obese PCOS versus obese controls and non obese PCOS versus non-obese controls. In stepwise linear regression PCOS was associated with CIMT and FMD independent of age, BMI and blood pressure. Young women with PCOS irrespective of their BMI have evidence for increased CVD risk as shown by increased CIMT and a lower FMD.

Clinical characteristics in Taiwanese women with polycystic ovary syndrome

PubMed Central

2015-01-01

Polycystic ovary syndrome (PCOS) is one of the most common hormonal endocrine disorders in women of reproductive age. It consists of a heterogeneous collection of signs and symptoms that together form a disorder spectrum. The diagnosis of PCOS is principally based on clinical and physical findings. The extent of metabolic abnormalities in women with PCOS varies with phenotype, body weight, age, and ethnicity. For general population, the prevalence of hyperandrogenism and oligomenorrhea decreases with age, while complications such as insulin resistance and other metabolic disturbances increase with age. Obese women with PCOS have a higher risk of developing oligomenorrhea, amenorrhea, hyperandrogenemia, insulin resistance, and lower luteinizing hormone (LH) to follicle stimulation hormone (FSH) ratios than non-obese women with PCOS. The LH to FSH ratio is a valuable diagnostic tool in evaluating Taiwanese women with PCOS, especially in the diagnosis of oligomenorrhea. Overweight/obesity is the major determinant of cardiovascular and metabolic disturbances in women of reproductive age. PMID:26473107

To investigate the presence of nonalcoholic fatty liver disease (NAFLD) in young lean women with polycystic ovary syndrome (PCOS) and insulin resistance (IR). Case control study. Women with PCOS and healthy controls in a metabolic day ward. Seventeen young lean women with PCOS and 17 matched controls were studied prospectively. Fasting blood and a glucose tolerance test. Ovarian and liver ultrasonography, and computed tomography (CT) of the liver (women with PCOS only). Anthropometric variables, biochemical and hormonal parameters, and several IR indices were determined. Hepatic lipid content was assessed with ultrasonography and CT of the liver. Women with PCOS had higher androgen levels, and the IR indices, glucose and insulin area under the curve, QUICKI, MATSUDA, and HOMA, compared to controls. In addition to IR, women with PCOS had normal aminotransferase levels, and higher, although within the normal range, alkaline phosphatase levels compared with controls. Women with PCOS had no evidence of NAFLD by either ultrasonography or CT of the liver. Young lean women with PCOS and IR do not have evidence of NAFLD. Because of the presence of IR, follow-up is required to determine whether they are at risk of developing NAFLD. Copyright 2010 American Society for Reproductive Medicine. Published by Elsevier Inc.

Polycystic ovary syndrome (PCOS) is a common endocrine disorder in adolescent girls that has both reproductive and metabolic implications. Patients with PCOS typically present to their pediatrician for evaluation of menstrual irregularity and/or signs of hyperandrogenism, such as hirsutism and acne. The diagnosis of PCOS is made by clinical symptoms and laboratory evaluation. Because of the long-term health consequences that can accompany the disorder, pediatricians should consider PCOS in their initial evaluation of menstrual irregularity. Lifestyle modification is the cornerstone of treatment for girls with PCOS; however, hormonal medication such as oral contraceptive pills and insulin-sensitizing agents are useful and effective adjuncts to therapy. The goals of treatment for girls with PCOS are to improve clinical manifestations of the disorder, health-related quality of life, and long-term health outcomes. Copyright 2015, SLACK Incorporated.

Insulin resistance and hyperinsulinemia play a key role in the pathogenesis of polycystic ovary syndrome (PCOS), which is characterized by hyperandrogenism, ovulatory dysfunction, and presence of polycystic ovaries on pelvic scanning. Insulin resistance is significantly associated with the long-term risks of metabolic syndrome and cardiovascular disease. Berberine has effects on insulin resistance but its use in women with PCOS has not been fully investigated. In this paper, we present a research design evaluating the effects of berberine on insulin resistance in women with PCOS. This is a multicenter, randomized, placebo-controlled and double-blind trial. A total of 120 patients will be enrolled in this study and will be randomized into two groups. Berberine or placebo will be taken orally for 12 weeks. The primary outcome is the whole body insulin action assessed with the hyperinsulinemic-euglycemic clamp. We postulate that women with PCOS will have improved insulin resistance following berberine administration. This study is registered at ClinicalTrials.gov, NCT01138930.

To decide if metformin augments clomiphene response for ovulation induction in non-obese women with polycystic ovary syndrome, a prospective randomised placebo-controlled trial was undertaken among 27 patients, who were found eligible for this study following clinical assessment and basic investigations. Women with polycystic ovary syndrome, even when non-obese, has increased insulin-resistance and do not respond favourably when treated with clomiphene for ovulation induction. The hypothesis is that by improving insulin- resistance and thus reversing from hyperinsulinaemia towards normal insulin secretion will enhance the responsiveness of these women to ovulation inducing effects of clomiphene. In the metformin group there were 15 patients who were given metformin 500mg orally 8 hourly daily for initial 3 months whereas in the placebo group there were 12 patients who were given folic acid (as placebo) 5mg orally once daily for initial 3 months. Thereafter, all the 27 patients in both groups were treated with clomiphene 50mg orally once daily from day 2 for 5 days in each month for subsequent 3 months. However, metformin and folic acid was continued in the metformin group and placebo group respectively for these subsequent 3 months when these patients were being treated with clomiphene for ovulation induction. Ovulation, as the outcome measure, was assessed by serial transvaginal ultrasound scanning from day 8/ day 9 and serum progesterone estimation on the 7th or 8th day following the ultrasound evidence of ovulation. Ovulation is taken to have occurred when serum progesterone was > or =8 ng/ml. Ovulation was noted to have occurred in 71.11% of the 45 cycles studied in 15 patients in the metformin group whereas ovulation occurred in 11.11% of the 36 cycles studied in 12 patients in the placebo group. This difference was highly statistically significant (p < 0.001) by Fisher's exact test. It can be conducted that metformin augments the ovulation inducing effects of

The morphological features of the ovaries in women with polycystic ovary syndrome (PCOS) have been well described by ultrasound imaging technology. These include enlarged ovary size, multiple small follicles of similar size, increased ovarian stromal volume and echogenicity, peripheral distribution of the follicles, and higher stromal blood flow. Ultrasound identification of the presence of polycystic ovarian morphology (PCOM) has been recognized as a component of PCOS diagnosis. With the advance of ultrasound technology, new definition has been proposed recently. There is, however, a paucity of data for the ovarian morphology in normal and PCOS adolescents. Magnetic resonance imaging has the potential to be an alternative imaging modality for diagnosing PCOM in adolescence. Copyright © 2016. Published by Elsevier Ltd.

PCOS (polycystic ovary syndrome) is called a pathology of the XX century and affects at least 10-15% women of childbearing age. The therapy involves pharmacotherapy of hormonal imbalance, as well as the change of lifestyle, including the diet. Performing the quantitative assessment of components of diets of women with PCOS, comparing the results with current dietary standards for Polish people and defining dietary requirements for the patients. The study was performed on 54 women of childbearing age (average age 26.03± 5.52) with PCOS syndrome diagnosed according to on the Rotterdam criteria. Anthropometric measurements of the patients were made and BMI and WHR calculated. Quantitative assessment of women’s diets was performed based on the analysis of 3-day food diaries and food records taken from the previous 24h with the interview method. The data were introduced to a dietary software DIETA 5.0, calculating the average intake of the energy, nutrients, vitamins, minerals, cholesterol and dietary fibre. The obtained results were compared to Polish dietary guidelines. Examined group was characterized by increased waist circumference (98.71± 13.6 cm) and an average WHR was 0.92± 0.08. An increased average value of BMI was also shown (28.91± 5.54 kg/m2). The patients consumed, on average, 1952.5±472.7 kcal daily, and the risk of insufficient intake of protein was determined in 36.7% of examined women. The highest risk of deficiency in minerals in women with PCOS was related to calcium (634 mg), potassium (3493 mg) and magnesium (250.1 mg), whereas with reference to vitamins deficiency as much as 70% of tested women were at risk of insufficient intake of folic acid, 36.7% of them - vitamin C, and 26.7% - vitamin B12. The average consumption of vitamin D was at the level of 3.4 μg. Test group was characterized by excessive average consumption of total fat (50%), SFA (70.4%) and saccharose (50%).

Introduction: The impact of pregnancy and parenthood on the long-term course of PCOS (polycystic ovary syndrome is still not known. The LIPCOS study (Lifestyle Intervention for Patients with Polycystic Ovary Syndrome [PCOS] - using the example of pregnancy and parenthood) systematically investigates long-term changes in PCOS symptoms. Method and Patients: The LIPCOS pilot study sent out a questionnaire to 403 patients who had presented with oligomenorrhea between 1991 and 2002. The prospective LIPCOS main study systematically investigated 64 women using structured interviews about lifestyle changes in the last 10 years, created a detailed hormone profile of these women and carried out vaginal ultrasound to calculate ovarian score. Results: Ovarian volume and ovarian score were not significantly lower for women with children (n = 25) compared to women with PCOS who had not had children (n = 39; p = 0.226). More women with children than women who did not have children currently reported a regular daily lifestyle, and the difference was statistically significant (92 % [n = 23/25] vs. 61.5 % [n = 24/39]; p = 0.009). Ten years ago or before the birth of their first child, respectively, no such difference was found between both groups (52 vs. 51.3 %). Over the last 10 years, women with children were more likely to have shorter cycles compared to women without children (p = 0.441). 88 % of women with children compared to 69.2 % of women without children reported that currently they had a "healthy diet" (p = 0.130). Serum testosterone levels were slightly lower for women with children (67.6 % of the upper limits of normal ranges) compared to women without children (80 % of the upper limits of normal ranges), but because of the small subgroup sizes the difference was not statistically significant (p = 0.106). Conclusion: The LIPCOS study shows for the first time that pregnancy and parenthood may have an impact on the long

Polycystic ovary syndrome (PCOS) is an endocrine disorder associated with several cardiometabolic risk factors, such as central obesity, insulin resistance, type 2 diabetes, metabolic syndrome, and hypertension. These factors are associated with adrenergic overactivity, which is an important prognostic factor for the development of cardiovascular disorders. Given the common cardiometabolic disturbances occurring in PCOS women, over the last years studies have investigated the cardiac autonomic control of these patients, mainly based on heart rate variability (HRV). Thus, in this review, we will discuss the recent findings of the studies that investigated the HRV of women with PCOS, as well as noninvasive methods of analysis of autonomic control starting from basic indexes related to this methodology.

Chronic low-grade inflammation has been suggested as a key contributor of the pathogenesis and development of polycystic ovary syndrome (PCOS). To investigate the association between oxidative stress status and inflammatory cytokines in follicular fluid of 21 PCOS women compared to 21 women with normal ovarian function who underwent intra-cytoplasmic sperm injection. Concentration of IL-6, IL-8, IL-10, and TNF-α was measured using sandwich ELISA. Oxidative stress was examined by measuring total oxidant status (TOS), malondialdehyde (MDA), total antioxidant capacity (TAC), and thiol groups. PCOS women had an elevated concentration of MDA and TOS compared to controls. Levels of TAC and thiol groups were lower in PCOS compared to controls. PCOS patients had a higher concentration of IL-6, IL-8, and TNF-α compared to controls. Concentration of IL-10 was lower in PCOS compared to controls. Significant correlations were found between MDA and TOS concentration with TNF-α and between IL-6 and MDA, IL-8 and TAC, IL-10 and TOS levels and also between IL-10 and TAC levels. TAC and thiol groups were negatively correlated with TNF-α. Increased oxidative stress in PCOS is associated with inflammation which is closely linked. Inflammation can induce production of inflammatory cytokines in this syndrome and directly stimulates excess ovarian androgen production.

To date no consensus has been reached on whether to administer statin to patients with Polycystic Ovary Syndrome (PCOS) routinely. Therefore, we conduct a meta-analysis to synthesize the literatures regarding therapeutic effects of statins on PCOS. A comprehensive literature search was performed using terms such as polycystic ovary syndrome, ovary polycystic disease, PCOS, hyperandrogaenemia; simvastatin, atorvastatin, lipidemic-modulating drugs, lipid lowering drugs, and testosterone; randomized controlled trials in the following bibliographic databases: Medline, Embase, Cochrane Controlled Trials Register. Identified reference lists were checked manually. In total, 4 RCTs were included. 3 of 4 studies were double-blinded while none reported whether of the data was analyzed using intention-to-treat analysis. Serum total testosterone and lipid profiles were included as investigation outcomes. Differences in reducing serum total testosterone were observed when comparing statin with placebo (Std MD= - 3.03, 95%CI - 5.85 ~ - 0.22, P=0.03) or statin + metformin with metformin (Std MD=- 1.07, 95%CI: - 2.06~ - 0.07, P=0.04). Heterogeneities were detected in both comparisons (I2=96% and 88% respectively). Meanwhile, statin was more effective than placebo in reducing LDL (WMD=- 0.87, 95%CI - 1.18~ - 0.55, P<0.0001), TC (WMD=- 1.23 95%CI - 1.35~ - 1.11, P<0.00001), TG (WMD= - 0.50, 95%CI - 0.73~ - 0.27, P<0.00001); and statin + metformin was more effective than metformin in lowering LDL (WMD= - 0.84, 95%CI: - 1.33 ~ - 0.354, P=0.0009), TC (WMD= - 1.28, 95%CI: - 1.47 ~ - 1.10, P<0.00001), and TG (WMD= - 0.27, 95%CI: - 0.36~ - 0.19, P<0.00001). Heterogeneities were detected during the meta-analysis. Statins can reduce the concentration of total testosterone, TC, TG and LDL. However, it cannot be concluded that statins have long-term benefit. A large-scale, randomized controlled study is needed to ascertain this uncertainty. © J. A.

Polycystic ovary syndrome (PCOS) is a heterogeneous endocrine disorder among reproductive-aged women. It is known to be associated with cardiovascular diseases. The aim of this study was to determine and compare the echocardiographic data of patients according to the phenotypes of PCOS. This study included 113 patients with PCOS and 52 controls. Patients were classified into four potential PCOS phenotypes. Laboratory analyses and echocardiographic measurements were performed. Left ventricular mass was calculated by using Devereux formula and was indexed to body surface area. Phenotype-1 PCOS patients had significantly higher homeostasis model assessment - insu-lin resistance (HOMA-IR) (p = 0.023), free testosterone (p < 0.001), LDL cholesterol levels (p < 0.001) and free androgen index (p < 0.001) compared with the control group. There were significant differences between groups regarding the septal thickness, posterior wall thickness, Left ventricular ejection frac-tion, E/A ratio and left ventricular mass index (for all, p < 0.05). PCOS patients with phenotype 1 and 2 had significantly higher left ventricular mass index than the control group (p < 0.001). In univariate and multivariate analyses, PCOS phenotype, modified Ferriman-Gallwey Score and estradiol were found as variables, which independently could affect the left ventricular mass index. This study showed that women in their twenties who specifically fulfilled criteria for PCOS phenotype-1 according to the Rotterdam criteria, had higher left ventricular mass index and decreased E/A ratio, which might be suggestive of early stage diastolic dysfunction.

Polycystic ovary syndrome (PCOS) is now recognized to be the most common endocrinopathy in women of reproductive age with a prevalence of 6.6-6.8%. PCOS, a syndrome of unknown etiology, was initially regarded as a reproductive disorder. However, in the last 15 years the role of insulin resistance (IR) has been identified as a significant contributor to the pathogenesis of PCOS, and the metabolic and cardiovascular sequelae of the syndrome have been increasingly appreciated. The coexistence and interaction of reproductive and cardiometabolic abnormalities in the context of PCOS have created a need for a modified therapeutic management of affected women. Insulin sensitizers, particularly metformin, have been introduced as a pharmaceutical option targeting not only IR, but several other aspects of the syndrome, including reproductive abnormalities. The landscape of the multifaceted actions of metformin evolves to broaden the therapeutic implications of this old drug in a new fashion for patients with PCOS. Most recently, the spectrum of metformin's targets has been expanded, and molecular studies have explored the tissue-specific mechanisms of metformin in the liver, the muscle, the endothelium, and the ovary. The use of metformin in pregnant women with PCOS comprises another scarcely explored, but promising area of research. This review attempts to cover the spectrum of metformin's cellular actions in different tissues and to summarize the current literature regarding the potential medical value of this medication in PCOS. Even if many of these actions are individually modest, they seem to be collectively sufficient to confer therapeutic benefits not only in cardiometabolic aspects but also in reproductive aspects of PCOS.

Glucose ingestion stimulates atherothrombotic inflammation in polycystic ovary syndrome

Women with polycystic ovary syndrome (PCOS) have chronic low-grade inflammation that can increase the risk of atherothrombosis. We performed a cross-sectional study to examine the effect of glucose ingestion on markers of atherothrombotic inflammation in mononuclear cells (MNC) of 16 women with PCOS (8 lean, 8 obese) and 16 weight-matched controls. Activator protein-1 (AP-1) activation and the protein content of early growth response-1 (EGR-1), matrix matalloproteinases-2 (MMP2), and tissue factor (TF) were quantified from MNC obtained from blood drawn fasting and 2 h after glucose ingestion. Plasma MMP9 and C-reactive protein (CRP) were measured from fasting blood samples. Truncal fat was determined by DEXA. Lean women with PCOS exhibited greater AP-1 activation and MMP2 protein content after glucose ingestion and higher plasma MMP9 and CRP levels than lean controls. Obese women with PCOS exhibited greater EGR-1 and TF protein content after glucose ingestion, and plasma CRP levels were even higher compared with lean subjects regardless of PCOS status. Truncal fat correlated with MMP9 and CRP levels and glucose-stimulated increases in AP-1 activation and EGR-1 and TF protein content. Testosterone correlated with glucose-stimulated AP-1 activation, and androstenedione correlated with MMP9 and CRP levels and glucose-stimulated AP-1 activation. Thus, both PCOS and obesity contribute to an atherothrombotic state in which excess abdominal adiposity and hyperandrogenism may be specific risk factors for developing atherothrombosis.

Polycystic ovary syndrome (PCOS) is an endocrine disorder among women of reproductive age characterized by chronic anovulation and polycystic ovary morphology and/or hyperandrogenism. Management of clinical manifestations of PCOS, such as menstrual irregularities and hyperandrogenism symptoms, includes lifestyle changes and combined hormonal contraceptives (CHCs). CHCs contain estrogen that exerts antiandrogenic properties by triggering the hepatic synthesis of sex hormone-binding globulin that reduces the free testosterone levels. Moreover, the progestogen present in CHCs and in progestogen-only contraceptives suppresses luteinizing hormone secretion. In addition, some types of progestogens directly antagonize the effects of androgens on their receptor and also reduce the activity of the 5α reductase enzyme. However, PCOS is related to clinical and metabolic comorbidities that may limit the prescription of CHCs. Clinicians should be aware of risk factors, such as age, smoking, obesity, diabetes, systemic arterial hypertension, dyslipidemia, and a personal or family history, of a venous thromboembolic event or thrombophilia. This article reports a narrative review of the available evidence of the safety of hormonal contraceptives in women with PCOS. Considerations are made for the possible impact of hormonal contraceptives on endocrine, metabolic, and cardiovascular health. PMID:29386951

Does second-hand smoke (SHS) exposure from husbands have adverse effects on sex hormones, metabolic profiles, clinical phenotypes and fertility outcomes in women with polycystic ovary syndrome (PCOS) undergoing ovulation induction? SHS exposure is associated with worsened biochemical hyperandrogenism, higher incidence of metabolic syndrome and reduced conception rates in women with PCOS. Smoking in women impairs fecundity at some stages of the reproductive process including folliculogenesis, embryo transport, endometrial angiogenesis and uterine blood flow. Yet little is known about the hazard of SHS exposure in women with PCOS. This study was a secondary analysis of the Polycystic Ovary Syndrome Acupuncture and Clomiphene Trial (PCOSAct), a large randomized controlled trial conducted at 27 hospitals from 2012 to 2015 in mainland China. Out of 1000 women with PCOS, SHS exposure status were available in 500 women, of whom 271 women were non-exposed and 229 exposed to cigarette smoke (170 women ≤10 cigarettes per day as low-SHS exposed and 59 women >10 cigarettes per day as high-SHS exposed). We compared circulating sex steroids, glucose and lipid metabolism, metabolic syndrome and phenotypes, fertility and obstetric outcomes between non-exposed and exposed women. Women exposed to SHS, compared to non-exposed women, had a higher serum total testosterone (1.7 vs 1.5 nmol/L, P = 0.01), free androgen index (5.7 vs 4.0, P = 0.001) and lower sex hormone binding globulin (30.1 vs 35.6 nmol/L, P = 0.03). Metabolic syndrome, but not other phenotypes, was more frequent in exposed women as compared to non-exposed women (21.8 vs 13.3%, adjusted odds ratio (OR)=1.66; 95% CI, 1.02-2.71, P = 0.04). Ovulation rates between exposed and non-exposed groups were not significantly different (76.9 vs 82.9%, adjusted OR=0.72; 95% CI, 0.45-1.15, P = 0.17). Conception rates were significant lower in the exposed group (26.6 vs 36.9%; adjusted OR=0.61; 95% CI, 0.41-0.91; P = 0.01), while

This study was intended to assess the effects of oral contraceptives given before treatment in infertile anovulatory patients with polycystic ovary syndrome who receive gonadotropins for controlled ovarian stimulation. Pretreatment with oral contraceptives increased the mono-ovulatory cycles, the duration of stimulation for noncanceled cycles, and the number of vials of gonadotropins used. It also reduced the number of dominant follicles and the peak E(2) levels for dominant follicles. No effect was observed in rates of cycle cancellation, pregnancy, abortion, live birth, multiple pregnancies, and ovarian hyperstimulation syndrome.

Chinese Herbal Medicine for the Optimal Management of Polycystic Ovary Syndrome.

PubMed

Ong, Madeleine; Peng, Jie; Jin, Xingliang; Qu, Xianqin

2017-01-01

Polycystic ovary syndrome (PCOS) is a complex heterogeneous disorder characterized by androgen excess and ovulatory dysfunction; it is now known to be closely linked to metabolic syndrome. Recent research suggests that insulin resistance plays an important role in the pathogenesis of PCOS which may lead to the excessive production of androgens by ovarian theca cells. Currently there is no single drug that can treat both the reproductive and metabolic complications of the disorder. Existing pharmaceutical agents such as hormonal therapies have been associated with side effects and are not appropriate for PCOS women with infertility. Additionally, insulin sensitizing agents useful for treating the metabolic abnormalities in PCOS have limited efficacy for treating reproductive aspects of the disorder. Chinese herbal medicines have a long history of treating gynaecological problems and infertility and therefore may be a novel approach to the treatment of PCOS. Current research demonstrates that the compounds isolated from herbs have shown beneficial effects for PCOS and when combined in an herbal formula can target both reproductive and metabolic defects simultaneously. Therefore, further investigation into Chinese herbal medicine in the treatment of PCOS is warranted.

Present status of understanding on the genetic etiology of polycystic ovary syndrome.

PubMed

Dasgupta, S; Reddy, B Mohan

Polycystic ovary syndrome (PCOS) is the most common endocrinopathy in women of reproductive age with a prevalence of approximately 7-10% worldwide. PCOS reflects multiple potential aetiologies and variable clinical manifestations. This syndrome is characterized by serious health implications such as diabetes, coronary heart diseases and cancer and also leads to infertility. PCOS can be viewed as a heterogeneous androgen excess disorder with varying degrees of reproductive and metabolic abnormalities determined by the interaction of multiple genetic and environmental factors. In this paper, we have attempted a comprehensive review of primarily molecular genetic studies done so far on PCOS. We have also covered the studies focusing on the environmental factors and impact of ethnicity on the presentation of this syndrome. A large number of studies have been attempted to understand the aetiological mechanisms behind PCOS both at the clinical and molecular genetic levels. In the Indian context, majority of the PCOS studies have been confined to the clinical dimensions. However, a concrete genetic mechanism behind the manifestation of PCOS is yet to be ascertained. Understanding of this complex disorder requires comprehensive studies incorporating relatively larger homogenous samples for genetic analysis and taking into account the ethnicity and the environmental conditions of the population/cohort under study. Research focused on these aspects may provide better understanding on the genetic etiology and the interaction between genes and environment, which may help develop new treatment methods and possible prevention of the syndrome.

Limited emphasis has been given to the molecular study of apomixis, an asexual method of reproduction where seeds are produced without fertilization. Most buffelgrass (Pennisetum ciliare (L.) Link syn = Cenchrus ciliaris L.) genotypes reproduce by obligate apomixis (apospory); however, rare sexual plants have been recovered. A modified differential display procedure was used to compare gene expression in unpollinated ovaries containing ovules with either sexual or apomictic female gametophytes. The modification incorporated end-labeled poly(A)+ anchored primers as the only isotopic source, and was a reliable and consistent approach for detecting differentially displayed transcripts. Using 20 different decamers and two anchor primers, 2268 cDNA fragments between 200 and 600 bp were displayed. From these, eight reproducible differentially displayed cDNAs were identified and cloned. Based on northern analysis, one cDNA was detected in only the sexual ovaries, two cDNAs in only apomictic ovaries and one cDNA was present in both types of ovaries. Three fragments could not be detected and one fragment was detected in ovaries, stems, and leaves. Comparison of gene expression during sexual and apomictic development in buffelgrass represents a new model system and a strategy for investigating female reproductive development in the angiosperms.

Polycystic ovary syndrome (PCOS) is the commonest endocrine disorder amongst women of reproductive age, which is characterized by reproductive and cardiometabolic disturbances with long-term health repercussions. Insulin resistance (IR), impaired glucose tolerance, type 2 diabetes mellitus (DM2), obesity and dyslipidemia occur more in women with PCOS than in age-comparable women without PCOS. Long term data regarding risks or benefits of medical intervention for metabolic dysfunction of PCOS are lacking. Therapies, such as oral contraceptives (OCPs) and anti-androgenic medications used to manage the reproductive manifestations of PCOS, may themselves be the cause of cardiometabolic perturbations. Hence, strategies regarding the management of reproductive issues in PCOS encompass a patient-specific tailored approach. Factors that influence the cardiometabolic side effects arising during treatment of the reproductive manifestations of PCOS (hirsutism/anovulation) are also discussed in this paper in order to build future strategies to minimize the overall cardiometabolic risk.

Polycystic ovary syndrome is a disorder which affects 5-10% of women in reproductive age. PCOS is a cause of hyperandrogenism, menstrual disorders and infertility. The most common clinical symptoms are hirsutism, acne and obesity. Patients often suffer from metabolic disorders: insulin resistance, hyperinsulinemia, dislipidemia, leading to atherosclerosis and others irregularities of the metabolic syndrome. Patients are in the high risk group for cardiovascular diseases (CVD) development because of the metabolic abnormalities. Obesity is observed in 35-60% of women with PCOS. Lean women with PCOS are also exposed to a greater risk of glucose intolerance development and abnormalities in lipid profile than women without PCOS with comparable BMI. Adipocytes are the source of many compounds of the paracrine and endocrine activity. Some of them are also markers and mediators of inflammation. Increased levels of proinflammatory cytokines in blood can promote atherosclerosis and cardiovascular disease. Markers: IL-18, TNF, IL-6 and hs-CRP are often elevated in patients with polycystic ovary syndrome. An increase in inflammatory markers may be an early indicator of the risk of developing insulin resistance and atherosclerosis, and may become a useful prognostic and therapeutic tool for monitoring patients with PCOS: lean and those with overweight and obesity. Assessment of the concentrations of inflammatory markers may become a very useful test in evaluating the risk of developing atherosclerosis and cardiovascular disease, long before their clinical manifestation. It will also allow for the appropriate prophylaxis.

Polycystic ovarian morphology (PCOM) is occasionally observed in women with hypothalamic amenorrhea (HA). Although these women with HA/PCOM meet two of the Rotterdam criteria, they are excluded from the diagnosis of polycystic ovary syndrome (PCOS) by having HA. We explored the coexistence of these two disorders in women with HA/PCOM by analyzing their androgen response to gonadotropins and by following their clinical characteristics over time. Baseline and dynamic endocrine profiles during controlled ovarian hyperstimulation for women with HA/PCOM [n = 6, median (interquartile range) age 30 yr (28-31), body mass index (BMI) 19.2 kg/m(2) (18.0-19.2)] were retrospectively compared with those of women with PCOS [n = 10, age 33 (31-34), BMI 24.8 (23.2-27.6)] and normoovulatory controls [n = 20, age 33 (31-35), BMI 21.5(20.3-23.1)]. Long-term outcomes for five women with HA/PCOM were followed during their spontaneous recovery from HA. With the exception of decreased LH [0.7 (0.3-0.8) vs. 6.0 IU/liter (4.8-7.4); P = 0.003], FSH [3.9 (2.5-5.7) vs. 7.5 IU/liter (5.3-9.5); P < 0.025], and estradiol [20 (14-24) vs. 32 pg/ml (20-39); P < 0.027], baseline endocrine profiles of women with HA/PCOM did not differ significantly from those of normoovulatory controls in terms of 17alpha-hydroxyprogesterone, dehydroepiandrosterone, dehydroepiandrosterone-sulfate, androstenedione, and total testosterone. However, controlled ovarian hyperstimulation with similar doses of gonadotropins resulted in an excess of androgen production compared with the controls [Deltaandrostenedione per dominant follicle 0.30 (0.23-0.37) vs. 0.10 ng/ml (0.05-0.18), P = 0.005; Deltatestosterone per dominant follicle 16 (7-24) vs. 6 ng/dl (2-12), P = 0.04], and these levels were comparable to those of women with PCOS. Recovery from HA/PCOM in some patients was associated with the development of oligomenorrhea and symptoms of androgen excess. Women with HA/PCOM may have inherently hyperandrogenic ovaries but

We analyzed two polymorphisms (-9C>G and IVS1+905A>G) within the BMP15 gene in women from Spain with polycystic ovary syndrome (PCOS). In this study, the BMP15 gene does not seem to be associated with PCOS. Nonetheless, we observed in both markers a genetic association with anovulation or infertility in these patients.

To compare the efficacy of clomiphene citrate (CC) plus tamoxifen with that of laparoscopic ovarian drilling in clomiphene-resistant women with polycystic ovary syndrome (PCOS). We randomly allocated 150 women with CC-resistant PCOS to a combined medication group (group 1) or a laparoscopic surgery group (group 2). The primary outcome was the live birth rate in each group; secondary outcomes were the rates of ovulation, clinical pregnancy and miscarriage. There were no significant differences between the groups regarding rates of ovulation (81.3% vs 85.3%), pregnancy (53.3% vs 50.7%), or live births (49.3% vs 44.0%), but the mean endometrium thickness was significantly greater on the day of human chorionic gonadotropin administration in group 1 (P<0.001). Clomiphene citrate plus tamoxifen was as effective as laparoscopic ovarian drilling in promoting ovulation and pregnancy.

Characterizing cardiovascular risk in women with polycystic ovary syndrome: more than the sum of its parts?

PubMed

Chang, Alice Y; Wild, Robert A

2009-07-01

Polycystic ovary syndrome (PCOS), a condition of irregular menses and androgen excess, is the most common endocrinopathy of young women. Insulin resistance is a well-established feature among many women with PCOS, even in the nonobese. Therefore, it is not surprising that PCOS is frequently associated with cardiovascular risk factors and the metabolic syndrome. However, it is not known whether PCOS is an independent risk factor for atherosclerosis and cardiovascular (CV) events or whether CV risk is attributable to associated risk factors. We review previous studies on CV risk and disease in women with PCOS, describing the pitfalls and challenges in ascribing CV risk to PCOS. Women with PCOS might be partly reassured that their relative risk approximates that of the metabolic syndrome (RR 1.5) and also strongly counseled at the individual level about the greatest potential threat to their CV health, the development of type 2 diabetes.

Injecting estradiol valerate (EV) to pre-pubertal or adult female rat results in effects similar to those observed in women with polycystic ovarian syndrome (PCOS). One of the mechanisms involved in PCOS development is the hyperactivity of the sympathetic nervous system. In EV-induced PCOS rats, the unilateral sectioning of the superior ovarian nerve (SON) restores ovulation of the innervated ovary. This suggests that, in addition to the sympathetic innervation, other neural mechanisms are involved in the development/maintenance of PCOS. The aims of present study were analyze if the vagus nerve is one of the neural pathways participating in PCOS development. Ten-day old rats were injected with EV dissolved in corn oil. At 24-days of age sham-surgery, unilateral, or bilateral sectioning of the vagus nerve (vagotomy) was performed on these rats. The animals were sacrificed at 90-92 days of age, when they presented vaginal estrous preceded by a pro-estrus smear. In EV-induced PCOS rats, unilateral or bilateral vagotomy restored ovulation in both ovaries. Follicle-stimulating hormone (FSH) levels in PCOS rats with unilateral or bilateral vagotomy were lower than in control rats. This result suggests that in EV-induced PCOS rats the vagus nerve is a neural pathway participating in maintaining PCOS. The vagus nerve innervates the ovaries directly and indirectly through its synapsis in the celiac-superior-mesenteric ganglion, where the somas of neurons originating in the SON are located. Then, it is possible that vagotomy effects in EV-induced PCOS rats may be explained as a lack of communication between the central nervous system and the ovaries.

To investigate whether the administration of an oral contraceptive containing the new antiandrogenic drospirenone is associated with reduced adrenal androgen synthesis in hyperandrogenic women with diagnosis of polycystic ovary syndrome. Drospirenone, an analogue of spironolactone and aldosterone antagonist, is a novel progestin under clinical development that is similar to the natural hormone progesterone, combining potent progestogenic with antimineralocorticoid and antiandrogenic activities. Prospective study. Healthy volunteers in University Department of Obstetrics and Gynecology. Fifteen women ages 18 to 28 years with the diagnosis of polycystic ovary syndrome. Three months of contraceptive use (30 mcg ethinylestradiol, 3 mg drospirenone). An adrenocorticotropic hormone test was performed before and after the study. Adrenal production of cortisol was unchanged after therapy with oral contraceptives. An interesting observation was reduced basal concentrations of androgens such as androstenedione, dehydroepiandrosterone sulfate, testosterone, and free testosterone during therapy. The ratios of the areas of substrates to products before and after oral contraceptive administration were compared for differences in 17alpha-hydroxylase (17-hydroxyprogesterone/progesterone) and 17,20-lyase (androstenedione/17-hydroxyprogesterone); activities were significantly reduced, indicating a reduction in the activities of these enzymes. The present results show for the first time that oral contraceptives containing drospirenone affect adrenal steroidogenesis by reducing synthesis and release of androgens in response to adrenocorticotropic hormone, leaving adrenal production of cortisol unchanged.

Polycystic ovary syndrome (PCOS) is the most common endocrine disorder in reproductive aged women and is characterized by two of the following three features: oligoovulation or anovulation, clinical and/or biochemical signs of hyperandrogenism, or polycystic ovaries. It has been demonstrated that PCOS includes a complex number of systemic symptoms in addition to symptoms related to the reproductive apparatus. It has been associated with obesity, metabolic syndrome, type 2 diabetes and an increased risk of cardiovascular disease. Several clinical and basic studies have investigated the link between PCOS and the cardiovascular disease risk, which seems to be due to blunted lipid/glucose metabolism, hypertension, and systemic inflammatory and coagulation disorders. Therefore, the current manuscript aims to review the main findings on PCOS and obesity/obesity-related disease (glucose derangements and cardiovascular disease risk factors). Although there are no long-term data on the morbidity and mortality for cardiovascular disease in PCOS, it is advisable to perform a careful metabolic and cardiovascular assessment in women with PCOS in order to tailor the most suitable strategy to prevent cardiovascular disease.

Functional hypothalamic amenorrhea is a disorder characterized by cessation of menstrual cycles in the absence of organic disease. In most patients, it occurs in adult life after a stressful event and may be related to a condition of mild chronic energy deprivation. The endocrine pattern is characterized by low estrogen levels with an absent response to a progestogen challenge test and low-normal gonadotropin levels. A few studies have shown that some of these women may have some features of polycystic ovary syndrome; these features include an increased androgen response to gonadotropins, increased anti-Mullerian hormone levels, and altered ovarian morphology or increased ovarian size. These findings suggest a link between these 2 completely different disorders: functional hypothalamic amenorrhea and polycystic ovary syndrome. The importance of the possible coexistence of these disorders in some women is important for follow-up of these women and in their treatment if they desire to become pregnant. To determine whether a subgroup of well-characterized women with functional hypothalamic amenorrhea may have the coexistence of polycystic ovary syndrome. Retrospective analysis of women with functional hypothalamic amenorrhea. Forty consecutive patients and 28 normal age-matched control patients were studied. Blood was obtained for serum anti-Mullerian hormone, androgens, and other hormone levels and all women had ovarian ultrasonographic measurements. In the entire group of women with functional hypothalamic amenorrhea, anti-Mullerian hormone and ovarian volume were greater than in control patients. In 13 patients (32.5%), anti-Mullerian hormone was elevated (>4.7 ng/mL, levels consistent with polycystic ovary syndrome) and in this group, ovarian volume was significantly greater than in the remaining patients with functional hypothalamic amenorrhea. Four of the 13 women with functional hypothalamic amenorrhea who had elevated anti-Mullerian hormone levels (10%), also

Polycystic ovary syndrome (PCOS) is a common endocrinopathy affecting reproductive-aged women. PCOS has been recognized as a syndrome combining reproductive and metabolic abnormalities with lifelong health implications. Cardiometabolic alterations require regular screening and effective and targeted lifestyle advice to lose weight as well as to prevent weight gain. Pharmacological therapy includes insulin-sensitizer drugs and agents that act directly on metabolic comorbidities, such as statins and antiobesity drugs. Bariatric surgery may be an option for severely obese women with PCOS Regarding reproductive aspects, ovulation induction with antiestrogens such as clomiphene citrate or letrozole is the first-line medical treatment. Exogenous gonadotropins and in vitro fertilization (IVF) are recommended as second-line treatment for anovulatory infertility. Laparoscopic ovarian diathermy may be used in special cases and metformin is no longer recommended for ovulation induction. Combined oral contraceptives (OCs) are the first-line treatment for the management of menstrual irregularities in women not seeking pregnancy, also providing endometrial protection and contraception. Progestin-only pills or cyclical progestins are recommended for those with contraindications to OCs. Metformin is also considered a second-line choice for improving menstrual cycles in women presenting insulin-resistance and dysglicemia. Hirsutism requires cosmetic procedures and medical treatment with OCs. More severe cases may need anti-androgen drugs added to the OCs. In conclusion, strategies regarding the management of reproductive issues in PCOS encompass a tailored approach to individual needs of each patient.

Complications and challenges associated with polycystic ovary syndrome: current perspectives

Polycystic ovary syndrome (PCOS) represents the most common endocrine dysfunction in fertile women and it is considered a heterogeneous and multifaceted disorder, with multiple reproductive and metabolic phenotypes which differently affect the early- and long-term syndrome’s risks. Women with PCOS present an adverse reproductive profile, including a high risk of pregnancy-induced hypertension, preeclampsia, and gestational diabetes mellitus. Patients with PCOS present not only a higher prevalence of classic cardiovascular risk factors, such as hypertension, dyslipidemia, and type-2 diabetes mellitus, but also of nonclassic cardiovascular risk factors, including mood disorders, such as depression and anxiety. Moreover, at the moment, clinical data on cardiovascular morbidity and mortality in women with PCOS are controversial. Finally, women with PCOS show an increased risk of endometrial cancer compared to non-PCOS healthy women, particularly during premenopausal period. Currently, we are unable to clarify if the increased PCOS early- and long-term risks are totally due to PCOS per se or mostly due to obesity, in particular visceral obesity, that characterized the majority of PCOS patients. In any case, the main endocrine and gynecological scientific societies agree to consider women with PCOS at increased risk of obstetric, cardiometabolic, oncology, and psychological complications throughout life, and it is recommended that these women be accurately assessed with periodic follow-up.

Polycystic ovary syndrome (PCOS) is a complex hormonal disorder characterized by reproductive, endocrine, and metabolic abnormalities. As the origins of PCOS remain unknown, mechanism-based treatments are not feasible and current management relies on treatment of symptoms. Hyperandrogenism is the most consistent PCOS characteristic; however, it is unclear whether androgen excess, which is treatable, is a cause or a consequence of PCOS. As androgens mediate their actions via the androgen receptor (AR), we combined a mouse model of dihydrotestosterone (DHT)-induced PCOS with global and cell-specific AR-resistant (ARKO) mice to investigate the locus of androgen actions that mediate the development of the PCOS phenotype. Global loss of the AR reveals that AR signaling is required for all DHT-induced features of PCOS. Neuron-specific AR signaling was required for the development of dysfunctional ovulation, classic polycystic ovaries, reduced large antral follicle health, and several metabolic traits including obesity and dyslipidemia. In addition, ovariectomized ARKO hosts with wild-type ovary transplants displayed normal estrous cycles and corpora lutea, despite DHT treatment, implying extraovarian and not intraovarian AR actions are key loci of androgen action in generating the PCOS phenotype. These findings provide strong evidence that neuroendocrine genomic AR signaling is an important extraovarian mediator in the development of PCOS traits. Thus, targeting AR-driven mechanisms that initiate PCOS is a promising strategy for the development of novel treatments for PCOS.

The aim of the present study was to evaluate the effect of modest weight reduction on serum concentrations of tumour necrosis factor alpha (TNF-alpha), TNF soluble receptors (sTNFRs) and interleukin-6 (IL-6) in obese women with polycystic ovary syndrome (PCOS). The study group consisted of 15 obese women with PCOS (mean age 28.5 +/- 7.7 years). Serum concentrations of TNF-alpha, sTNFRs and IL-6, insulin, FSH, LH, DHEAS, androstendione, total and free testosterone, cortisol, 17OH-progesterone, oestradiol and sex hormone binding globulin (SHBG), glucose, total cholesterol, HDL cholesterol and triglycerides were measured before treatment and after 10% weight loss. All patients were advised to follow a 1000-1200 kcal diet with a limited intake of simple carbohydrate and animal fats and to exercise regularly (30 min, 3 times a week). Body composition was measured by bioimpedance. Serum concentrations of TNF-alpha, sTNFRs and IL-6 were determined by enzyme linked immunosorbent assay (ELISA). Plasma insulin, FSH, LH, DHEAS, androstendione, total and free testosterone, cortisol, 17OH-progesterone, oestradiol and SHBG were measured by a commercial RIA. Blood glucose, total cholesterol, HDL cholesterol and triglycerides were measured by an enzymatic procedure. We observed no differences in serum concentrations of TNF-alpha, sTNFRs or IL-6 after treatment. It seems that more than a modest weight reduction is necessary to obtain a decrease in serum concentrations of proinflammatory cytokines and an improvement in ovarian function in obese women with polycystic ovary syndrome.

To compare the effects of cognitive-behavioral therapy (CBT) and lifestyle modification (LS) versus LS alone on weight, depressive and anxiety symptoms, and stress response in women with polycystic ovary syndrome (PCOS), overweight/obesity, and depressive symptoms. A 16-week pilot randomized clinical trial. Tertiary-care PCOS center. Overweight/obese women with PCOS and depressive symptoms. Weekly CBT (n = 7) or contact only/no therapy (n = 8) for 8 weeks. Both groups received weekly LS for 16 weeks. Changes in weight, depression (Center for Epidemiologic Studies Depression Scale [CES-D]), anxiety (State-Trait Anxiety Inventory [STAI]), quality of life (Polycystic Ovary Syndrome Health-Related Quality of Life Questionnaire [PCOSQ]), laboratory tests, and response to a Trier Social Stress Test (TSST). The CBT+LS group lost more weekly weight (-0.35 kg/wk vs. -0.16 kg/wk) compared with the LS group. Overall, the CBT+LS group lost 3.2 kg versus 1.8 kg for the LS group. The CBT+LS group had greater improvement in PCOSQ at 8 weeks (+3.7 vs. +1.2 points). In the overall cohort, STAI and CES-D decreased by -0.27 points per week and -0.31 points/wk, respectfully, and total and free T decreased at week 8. Heart rate response to TSST was lower at 15 minutes after stressor in the CBT+LS group. Weekly CBT+LS for 8 weeks compared with LS alone resulted in significant weight loss and improved quality of life in overweight/obese women with PCOS and depressive symptoms. These interventions were associated with a decreased autonomic response to a laboratory stressor, suggesting a potential link between CBT, weight loss, and modulation of the stress response.
