    Exposure to stress during puberty can lead to long-term behavioral alterations in adult rodents coincident with sex steroid hormone-dependent brain remodeling and reorganization. Social isolation is a stress for social animals like mice, but little is known about the effects of such stress during adolescence on later reproductive behaviors. The present study examined sexual behavior of ovariectomized, estradiol and progesterone primed female mice that were individually housed from 25 days of age until testing at approximately 95 days, or individually housed from day 25 until day 60 (during puberty), followed by housing in social groups. Mice in these isolated groups were compared to females that were group housed throughout the experiment. Receptive sexual behaviors of females and behaviors of stimulus males were recorded. Females housed in social groups displayed greater levels of receptive behaviors in comparison to both socially isolated groups. Namely, social females had higher lordosis quotients (LQs) and more often displayed stronger lordosis postures in comparison to isolated females. No differences between female groups were observed in stimulus male sexual behavior suggesting that female "attractiveness" was not affected by their social isolation. Females housed in social groups had fewer cells containing immunoreactive estrogen receptor (ER) α in the anteroventral periventricular nucleus (AVPV) and in the ventromedial nucleus of the hypothalamus (VMH) than both isolated groups. These results suggest that isolation during adolescence affects female sexual behavior and re-socialization for 1 month in adulthood is insufficient to rescue lordosis behavior from the effects of social isolation during the pubertal period.

    Recent syndemic models of sexual health disparities affecting racial/ethnic minorities have highlighted the role of discrimination. Yet no previous work has examined how acculturative stress (distress at the transition from one's original culture toward a new culture) associates with sexual HIV-risk behavior (SHRB). Work among other minority populations suggests sexual compulsivity (SC) may contribute to syndemic sexual health disparities as a means of coping with distress. With this in mind, the present study examined whether SC explained the relation between acculturative stress and SHRB. Separate analyses were conducted for males and females within a sample of 758 sexually initiated racial/ethnic minority college students. Among males and females, acculturative stress had an indirect effect on SHRB via SC. As the first study to examine SHRB in relation to acculturative stress, findings provide preliminary evidence that targeting SC among racial/ethnic minorities may help reduce sexual health disparities.

    In a sample of urban youth (N = 1,070), we examined the links between primary caregiver affect (i.e., warmth and hostility) and two measures of sexual behavior in adolescence--early sexual initiation and sex with multiple partners. We also examined the extent to which neighborhood disadvantage moderated associations between caregiver affect and…

    In rats, exposure to the polychlorinated biphenyl congener 3, 4, 3', 4'-tetrachlorobiphenyl (PCB 77) affects the brain and behavior of the offspring as well as the maternal behavior of the dams. In the present study, a cross-fostering design was used to examine the effects of pre- and/or postnatal exposure to PCB 77 on sexual behavior and partner preference in female rats, and to determine the role of altered maternal behavior in the mediation of these effects. Pregnant rats were treated with oil or PCB dissolved in oil (2 mg/kg b.w.) on gestation days 6-18 and then given pups that had been exposed to either the oil vehicle or PCB during gestation. As adults, the female offspring were tested for partner preference (that is, whether they preferred to spend time with a sexually receptive female or a sexually active male) and sexual behavior. None of the treatments affected female sexual behavior. However, both double exposure and postnatal exposure diminished the animals' preference for a male over a female stimulus, but partner preference was not affected by prenatal exposure alone. There were no significant correlations between the changes in partner preferences due to PCB exposure and the amount of maternal grooming and licking received by the treated litters. Thus, female partner preference is affected by early PCB exposure, and the effects depend upon whether the exposure is in utero or via lactation and may be independent of any effects of the PCB on maternal care.

  6. Operational sex ratio and density do not affect directional selection on male sexual ornaments and behavior.

    2008-01-01

    Demographic parameters including operational sex ratio (OSR) and population density may influence the opportunity for, and strength of sexual selection. Traditionally, male-biased OSRs and high population densities have been thought to increase the opportunity for sexual selection on male sexual traits due to increased male competition for mates. Recent experimental evidence, however, suggests that male-biased OSRs might reduce the opportunity for sexual selection due to increased sexual coercion experienced by females. How OSR, density, and any resultant changes in the opportunity for sexual selection actually affect selection on male sexual traits is unclear. In this study, we independently manipulated OSR and density in the guppy (Poecilia reticulata) without altering the number of males present. We recorded male and female behavior and used DNA microsatellite data to assign paternity to offspring and estimate male reproductive success. We then used linear selection analyses to examine the effects of OSR and density on directional sexual selection on male behavioral and morphological traits. We found that females were pursued more by males in male-biased treatments, despite no change in individual male behavior. There were no differences in sexual behavior experienced by females or performed by males in relation to density. Neither OSR nor density significantly altered the opportunity for sexual selection. Also, Although there was significant multivariate linear selection operating on males, neither OSR nor density altered the pattern of sexual selection on male traits. Our results suggest that differences in either OSR or density (independent of the number of males present) are unlikely to alter directional evolutionary change in male sexual traits.

    This study investigated the association between drugs and sexual behavior in a sample of polydrug substance abusers recruited from several Italian therapeutic communities; participants were 90 polydrug substance abusers (opiates, cocaine, amphetamine, inhalants, marijuana/sedatives or hallucinogens abusers) who were compared with 90 nonsubstance-abusing individuals. Sexual behavior was measured by the Italian version of the Sex and the Average Woman (or Man; SAWM), a questionnaire that assesses different kind of sexual attitudes. Results showed that drug-abusing individuals are particularly inclined to search for sexual intercourse and are open to different kinds of sexual experiences; however, they have difficulties in establishing committed and deep relationships with their partners, showing signs of inhibition, affective detachment or anger. Their sexual lives are also surrounded by negative emotions, disturbing thoughts and maladjusted behaviors. The importance of integrating sexual problems into therapeutic strategies is discussed.

    Reproductive behavior in male rodents is made up of anticipatory and consummatory elements which are regulated in the brain by sensory systems, reward circuits and hormone signaling. Gonadal steroids play a key role in the regulation of male sexual behavior via steroid receptors in the hypothalamus and preoptic area. Typical patterns of male reproductive behavior have been characterized, however these are not fixed but are modulated by adult experience. We assessed the effects of repeated sexual experience on male reproductive behavior of C57BL/6 mice; including measures of olfactory investigation of females, mounting, intromission and ejaculation. The effects of sexual experience on the number of cells expressing either androgen receptor (AR) or estrogen receptor alpha (ERα) in the primary brain nuclei regulating male sexual behavior was also measured. Sexually experienced male mice engaged in less sniffing of females before initiating sexual behavior and exhibited shorter latencies to mount and intromit, increased frequency of intromission, and increased duration of intromission relative to mounting. No changes in numbers of ERα-positive cells were observed, however sexually experienced males had increased numbers of AR-positive cells in the medial preoptic area (MPOA); the primary regulatory nucleus for male sexual behavior. These results indicate that sexual experience results in a qualitative change in male reproductive behavior in mice that is associated with increased testosterone sensitivity in the MPOA and that this nucleus may play a key integrative role in mediating the effects of sexual experience on male behavior.

    2013-08-01

    In this article we examine how members of fishing communities on the shores of Lake Victoria in Uganda respond to HIV diagnosis in terms of disclosure to sexual partners. We then explore the subsequent changes in sexual behavior and relationships. To access this information, we collected life history data from 78 HIV-positive individuals in five fishing communities. We found that the strength of the sexual relationships shaped how and why individuals disclosed to partners, and that these relationships tended to be stronger when partners shared familial responsibility. Those who perceived their current sexual partnership to be weak sought to conceal their status by maintaining prediagnosis patterns of sexual behavior. The majority of the study's participants rarely changed their sexual behavior following HIV diagnosis, regardless of their relationship's strength. These findings elucidate barriers to disclosure and behavior change, and suggest that a life-course approach might enhance individual-level counseling so that counselors can provide tailored support to individuals regarding disclosure decisions and outcomes.

  13. Inappropriate sexual behavior.

    1996-11-01

    Inappropriate sexual behavior, or sexually aggressive behavior, is a term which encompasses a variety of behaviors, including obscene gesturing, touching or hugging another person, exposing body parts or disrobing, and masturbating in public. Inappropriate sexual behavior often elicits feelings of anxiety, embarrassment, or unease in the caregiver and the result is often disruption in continuity of care for the patient. The cause of inappropriate sexual behavior varies among individuals and careful assessment of the etiology of the behavior is the first essential step in intervening. Nursing interventions focus upon providing opportunities for expression of appropriate sexual behavior while attempting to extinguish inappropriate sexual behavior.

  14. Pathways from childhood abuse to prospective revictimization: depression, sex to reduce negative affect, and forecasted sexual behavior.

    Research suggests that adverse events in childhood, such as childhood physical, sexual, and emotional abuse, confer risk for later sexual assault. Psychological distress, coping strategies, and sexual behavior may help explain the path from childhood abuse to revictimization. The present study explored how the use of sex to regulate negative affect (SRNA) operates independently, and in combination with other psychosocial factors to increase college women's (N=541) risk of experiencing prospective adult sexual assault (ASA). Sequential multiple mediator models in Mplus were used to assess the effect of three different forms of childhood abuse on prospective ASA, both independently and while controlling for other forms of childhood abuse. The indirect effect of adolescent sexual assault (AdolSA), depressive symptoms, SRNA, and participants' response to a sex-related vignette was tested using bias-corrected bootstrapping. In the full path model, childhood emotional abuse and AdolSA predicted ASA, while childhood physical and sexual abuse were directly associated with AdolSA, but not ASA. Additionally, depressive symptoms and participants' estimate of their likely behavior in a sex-related vignette directly predicted prospective ASA. Results using bootstrapping revealed that a history of childhood abuse predicted prospective ASA via diverse direct and indirect paths, as well as through a similar multiple mediator path. Overall, findings suggest that a combination of affective, coping, and sexual expectancy factors contribute to risk for revictimization in adult survivors of childhood abuse. Future research directions and targets for risk-reduction programming are discussed.

  15. Exposure to methylphenidate during peri-adolescence affects endocrine functioning and sexual behavior in female Long-Evans rats.

    The present study was designed to test the effects of methylphenidate (MPH) exposure on the maturation of endocrine functioning and sexual behavior. Female rat pups received either MPH (2.0mg/kg, i.p.) or saline twice daily between postnatal days 20-35. This period of exposure represents the time just prior to puberty as well as puberty onset. Approximately five weeks after the last injection of MPH or saline, female subjects were hormone-primed and tested during their first sexual experience. Subjects were given the choice to interact with a sexually active male or a sexually receptive female rat (i.e., the partner-preference test). The partner-preference paradigm allows us to assess multiple aspects of female sexual behavior. MPH exposure during peri-adolescence delayed puberty and, when mated for the first time, affected sexual behavior (e.g., increased time spent with the male stimulus and decreased the likelihood of leaving after mounts) during the test of partner preference. When monitoring estrous cyclicity, female subjects treated with MPH during peri-adolescence frequently experienced irregular estrous cycles. The results of the present study suggest that chronic exposure to a therapeutic dose of MPH around the onset of puberty alters long-term endocrine functioning, but with hormone priming, increases sensitivity to sexual stimuli.

    Using a sample of 1117 female college students, this study examined emotional, behavioral, and social-cognitive mechanisms of sexual abuse revictimization. It was hypothesized that numbing, alexithymia, alcohol problems, mistrust, and adult attachment dimensions would mediate the relationship between childhood sexual abuse (CSA) and adult sexual abuse (ASA). Aside from the close adult attachment dimension, the results indicated that all of the hypothesized mediators were associated with CSA. However, only alcohol problems and mistrust met the necessary conditions of mediation. The results with respect to mistrust are especially unique in that it is one of the first empirical demonstrations of a social-cognitive mechanism for sexual abuse revictimization. Thus, these results enhance our understanding of interpersonal mediators of the relationship between CSA and ASA and provide a new direction for future research.

    Reproductive behavior and physiology in adulthood are controlled by hypothalamic sexually dimorphic neuronal networks which are organized under hormonal control during development. These organizing effects may be disturbed by endocrine disrupting chemicals (EDCs). To determine whether developmental exposure to Ethinylestradiol (EE2) may alter reproductive parameters in adult male mice and their progeny, Swiss mice (F1 generation) were exposed from prenatal to peripubertal periods to EE2 (0.1-1 μg/kg/d). Sexual behavior and reproductive physiology were evaluated on F1 males and their F2, F3 and F4 progeny. EE2-exposed F1 males and their F2 to F4 progeny exhibited EE2 dose-dependent increased sexual behavior, with reduced latencies of first mount and intromission, and higher frequencies of intromissions with a receptive female. The EE2 1 μg/kg/d exposed animals and their progeny had more calbindin immunoreactive cells in the medial preoptic area, known to be involved in the control of male sexual behavior in rodents. Despite neuroanatomical modifications in the Gonadotropin-Releasing Hormone neuron population of F1 males exposed to both doses of EE2, no major deleterious effects on reproductive physiology were detected. Therefore EE2 exposure during development may induce a hypermasculinization of the brain, illustrating how widespread exposure of animals and humans to EDCs can impact health and behaviors.

  19. How REM sleep deprivation and amantadine affects male rat sexual behavior.

    PubMed

    Ferraz, M R; Ferraz, M M; Santos, R

    2001-01-01

    There are conflicting findings about the sexual effects of REM sleep deprivation (REMd). Otherwise, several studies show a dopaminergic hypersensitivity after REMd. The effect of REMd and amantadine (AMA) was studied for standard measures and temporal patterning in the first experiment, in four groups: normal with vehicle, normal with AMA (5.0 and 10 mg/kg), REMd with vehicle and REMd with AMA (5.0 and 10.0 mg/kg). REMd reduced mount latency (ML), intromission latency (IL) and mount number (MN) and increased copulatory efficiency (CE) and hit rate factor. REMd also reduced the mount bout number (MBN) and increased the sexual interaction (mount bout time, MBT) among male and female during copula. AMA stimulates initiation and hit rate factors and accelerates the temporal patterning of sexual behavior, evoking fewer and quicker mount bouts. In the experiments with combination of REMd and AMA administration, AMA did not increase behavior effects evoked by REM deprivation, probably due to a top or a bottom effect, depending on the measures considered. A second experiment studied the effects of AMA (1.25 to 5.0 mg/kg) and REMd on the sexual reflexes of nonimmobilized male rats. REMd enhanced the AMA effects upon the seminal emission reflex, but inhibited the penile erection reflex elicited by 1.25 mg/kg of AMA. Curiously, our results showed that REMd, like AMA, a dopaminergic agonist, causes similar effects of sexual behavior in the male rat, particularly those related to arousal mechanism and hit rate factor. The results are discussed and the effects of REMd probably involve dopaminergic hypersensitivity and increased sexual motivational response.

    Late-onset hypogonadism (LOH) is a clinical syndrome characterized with aging and declined serum testosterone levels. Sexual symptoms are also essential for the diagnosis of LOH. Testosterone replacement therapy is used widely to treat LOH. However, the side effects of it should not be ignored, such as fluid retention, hypertension and spermatogenic suppression. Therefore, alternate treatment modalities have been pursued. Herbal medicines used widely in China have achieved satisfying results with little side effects. Nonetheless, there are few pharmacological researches on them. In this study, 24-month-old mice were used as LOH animal models to explore the pharmacological effects of a herbal medicine, saikokaryukotsuboreito (SKRBT), on serum testosterone levels and sexual functions. Furthermore, the expression of steroidogenic acute regulatory (StAR) protein, a kind of rate-limiting enzyme of testosterone synthesis, was also examined. As a result, SKRBT improved the serum testosterone levels of these mice at a dose of 300 and 450 mg/kg. Multiple measures of sexual behavior were enhanced. The expression of StAR was also increased. Therefore, this study suggested that SKRBT can improve the serum testosterone levels by activating the expression of StAR and might be a viable option to treat sexual symptoms caused by LOH.

    Xenoestrogens are endocrine-disrupting chemicals that mimic the action of endogenous estrogen hormones. Effects of xenoestrogen on aquatic wildlife are well documented, whereas the experimental evidence for impairment of reproductive behavior and physiology in mammals after exposure to xenoestrogens has been debated. The strongest arguments against such studies have been that the route, time course, and intensity of exposure did not simulate environmental exposure and that the chemicals tested have additional nonestrogenic toxic effects, hindering generalization of actual xenoestrogenic effects. Here we show that environmental-like exposure to the pure estrogen 17alpha-ethinylestradiol during development alters reproductive behavior and physiology in adult female Sprague-Dawley rats. We simulated environmental exposure by giving low doses (0.4 and 0.004 microg/kg.d) of 17alpha-ethinylestradiol orally to pregnant females from conception to weaning of the pups, which continued to receive the treatment until puberty. We studied the sexual behavior, estrous cycle, and estradiol plasma levels of intact female rats when they reached 3 months of age. Exposure to the higher dose strongly affected female sexual behavior and physiology, with suppression of lordosis and the estrous cycle and enhanced aggression toward males. The lower dose disrupted appetitive components of sexual behavior that influence the rate of copulation. Estradiol plasma levels were not affected by the treatment. Our study revealed that exposure to low oral doses of a pure estrogen during development alters female sexual behavior and physiology. These results suggest potential risks of reproductive failure from xenoestrogen exposure in realistic ecological conditions.

    Intact adult male rats, in which aromatization of testosterone to estradiol was prevented pre- and/or neonatally by ATD (1,4,6-androstatriene-3,17-dione), were repeatedly tested for partner preference behavior (choice: estrous female vs active male). In consecutive tests increasing preference scores for the female were found. Neonatal ATD males showed significantly lower preference scores for an estrous female than controls or prenatal ATD males. Prenatal ATD caused preference scores only slightly lower than those of controls. Ejaculation frequencies were markedly reduced or even absent in neonatal ATD males. Prenatal ATD treatment only had no or a moderately lowering effect on ejaculation frequency. Lordosis behavior of adult intact males was more facilitated following neonatal ATD treatment than following prenatal ATD treatment. In a number of tests the serotonergic drug 8-OH-DPAT was injected prior to testing for sexual partner preference and copulatory behavior. DPAT significantly increased preference for an estrous female in all groups of males when interaction was possible, but had no effect when sexual interaction was prevented by wire mesh. DPAT was able to increase the number of ejaculators in nonejaculating groups (i.e., perinatally ATD-treated males). "Premature ejaculations," i.e., ejaculations with the first intromission, were frequently observed with DPAT treatment in all groups of males. In conclusion, the availability of neonatal estrogen (derived from testosterone) organizes, at least partially, the preference for an estrous female normally shown by adult male rats. The lack of neonatal estrogen causes males to be less masculinized, both in partner preference behavior and ejaculatory behavior, and less defeminized in lordosis behavior.(ABSTRACT TRUNCATED AT 250 WORDS)

    Selective phosphodiesterases (PDEs) inhibitors have been widely studied as therapeutic agents for treatment of various human diseases, including cardiotonics, vasodilators, smooth muscle relaxants, antidepressants, antithrombotics, antiasthmatics, and agents for improving learning and memory. Although Sildenafil(®) and Vardenafil(®) have similar chemical formulae, the same target and interact with many of the same residues at the active site of phosphodiesterse-5 (PDE-5), they exhibit both in vitro and in vivo some important functional differences that could differentially affect behavior. Therefore we assessed whether repeated and chronic administration of Vardenafil and Sildenafil at a dose based upon human treatment can differentially affect aggressive, social, emotional and sexual behavior. To this aim, the effects of Sildenafil (10mg/kg) or Vardenafil (2mg/kg) (t.i.w., for 5 weeks) were observed in CD1 subordinate male mice in a low aggression and social subordination context. The results show that Sildenafil increased competitive aggression, environmental and social exploration, and reduced anxiety like behaviors as compared to controls, whereas Vardenafil had a significant major effect on appetitive and consummatory aspect of sexual behavior. This demonstrates that Sildenafil and Vardenafil, although being structurally and functionally similar, are characterized by different neuro-behavioral actions and can have differential therapeutic potentials.

    Case material is presented from two patients suffering from addictive sexual behavior. The term addiction is used because of the intense, driven quality of the behavior and because of its mood-elevating effects. Psychodynamically, the patients' sexual acts helped to undo feelings of rejection at the hands of their mothers and to enhance feelings of lovability and of self-esteem. The behavior also helped to neutralize powerful feelings of rage toward the mother. In one patient, the acts also helped to ease inner turmoil related to an underlying attention deficit disorder. I speculate that some adults with addictive sexual behavior may have underlying attention deficit disorders. In both my patients, the sexual behaviors served the self-regulatory function of alleviating inner feelings of anhedonia and depression. When they decreased their sexual activities during the course of the treatment, they required adjunctive antidepressant medication. The underlying meaning of the medication and countertransference attitudes toward such patients are explored.

    There are limited studies on the prevalence and correlates of sexual risk behavior among adolescents in Pacific Island countries. In order to inform public sexual and reproductive health interventions, the aim of this study was to assess the prevalence and correlates of various sexual risk behaviors among in-school adolescents in 4 Pacific Island countries using data from the Global School-Based Health Survey. In a cross-sectional study, 6792 school-going adolescents (49.7% boys and 50.3% girls; 13-16 years old) from Fiji, Kiribati, Samoa, and Vanuatu were surveyed with a self-administered questionnaire. Overall, 18.9% of students reported to ever had sex (ranging from 12.9% in Vanuatu to 57.5% in Samoa), and of those sexually active, 38.0% had an early sexual debut (<14 years), 38.1% had 2 or more sexual partners during their lifetime, 39.5% had not used a condom at last sex, 50.9% had not used birth control at last sex, and 77.8% engaged in sexually risky behavior using a composite measure. Multivariate logistic regression found that male sex, older age, tobacco use, alcohol use, mental distress, having no close friends, and truancy were associated with several of 5 or all 5 sexual risk behaviors. Sexual and reproductive health promotion programs are indicated to address the high risk of sexually transmitted infection, HIV, and pregnancy in this adolescent population. PMID:27242369

    The purpose of this study was to analyze changes in early adolescents' intimate behaviors and the initiation of sexual intercourse over a one-year time period. The changes are interpreted within the context of recent progress in understanding the development of early adolescents. Public school students in sixth and ninth grades of selected schools in a midwestern industrial city were studied in two waves of data collection. A total of 106 students provided data for the second year, allowing comparisons of their Time 2 with their Time 1 responses. Five of eight intimate behaviors studied increased in frequency during the year. Also, the adolescents' perceived benefits of having sexual intercourse increased and perceived costs decreased during the follow-up year. Increases in the frequency of intimate behaviors but not changes in their perceptions of the benefits and costs predicted whether or not students had initiated sexual intercourse during the follow-up period. These findings support current understanding of early adolescence as a time of incremental learning about intimacy and about sexual relationships. The findings suggest that preventing early sexual intercourse may require understanding the specific behavioral competencies related to healthful development of intimacy. Pediatric nurses can be leaders in providing the necessary counseling and education to young adolescents, their families, and their communities.

    Prostitution involves the exchange of sexual services for economic compensation. As sexual behaviour is an important determinant in transmitting HIV and sexually transmitted diseases (STDs), sex workers (SWs), transgenders and clients are often labeled as a "high risk group" in the context of HIV and STDs. It has been documented that female sex workers in particular have an increased prevalence of untreated STDs and have been hypothesized to affect the health and HIV incidence of the general population. People involved in prostitution are a cause for concern from both public health and economic perspectives. However, little is known about why they remain in this type of activity given the risks prostitution presents, and even less is known about how to intervene and interrupt the complex cycle of prostitution. The aim of this paper is to provide a clinical and epidemiological analysis of the relationship between prostitution, sexual behavior and outbreaks of STDs; to assess the role that migrants, transgenders and clients of SWs have in prostitution and in the outbreaks of STDs. In addition, we also want to highlight how new sexual networks, like the Internet, have become an increasingly important vehicle to sharing information about prostitution, sexual behavior and STDs. Finally we present what may be the prevention strategies and the goals in order to stem the spread of STDs among these hard-to-access groups. PMID:23007210

    Understanding the role of socio-sexual cognitions and religiosity on adolescent sexual behavior could guide adolescent sexual health efforts. The present study utilized longitudinal data from 328 young women to assess the role of religion and socio-sexual cognitions on sexual behavior accrual (measuring both coital and non-coital sexual behavior). In the final triple conditional trajectory structural equation model, religiosity declined over time and then increased to baseline levels. Additionally, religiosity predicted decreased sexual conservatism and decreased sexual conservatism predicted increased sexual behavior. The final models are indicative of young women's increasing accrual of sexual experience, decreasing sexual conservatism and initial decreasing religiosity. The results of this study suggest that decreased religiosity affects the accrual of sexual experience through decreased sexual conservatism. Effective strategies of sexual health promotion should include an understanding of the complex role of socio-sexual attitudes with religiosity.

    Objective Assessment of mental health is important in understanding sexual risk behavior in adolescents, yet few studies have examined how affect is directly related to sexual behavior. Momentary sampling (MS) methods permit real-time assessment of affect in relation to specific events and embed the collected data in the context of the respondent’s moment-to-moment life. The objectives of this study were to review the literature on affect and sexual behavior and to compare the feasibility and acceptability of MS with diaries and retrospective self-report as a means of collecting temporally relevant data on affect and sexual behavior in adolescents. Methods Sexually active, nondepressed adolescent outpatients who were aged 15 to 18 years were randomly assigned to a schedule of the 3 methods of data collection for 2 weeks each. All participants completed a retrospective self-report by interview at the end of each 2-week period. In the diary arm, participants completed twice-daily paper-and-pencil diary cards, which were returned by mail. In the MS arm, participants used 2-way pagers to respond to several random pages per day. Primary outcomes included rates of completion (diaries vs MS reports) and the participants’ tolerance of and preferences for the methods. A secondary outcome was the agreement in means for positive and negative affect and in report of days on which substance use and sexual activity occurred. Associations of affect with contextual factors and with sexual activity were also explored in the MS arm. Results Ten youths completed 30 of 30 retrospective self-reports (100%, 3 per participant, by design), 254 of 280 diaries (91%; mean: 25.4 per participant), and 442 of 600 MS reports (74%; mean: 44.2 per participant). Most participants preferred the MS method to the diaries or retrospective self-report. Affect scores and reports of sexual activity and substance use were correlated among the methods. Measured with MS, affect was found to differ by

    This study examined the relationships between childhood attachment and coercive sexual behavior. One hundred sixty-two male undergraduate students completed self-report measures of childhood maternal attachment, childhood paternal attachment, adult attachment, antisociality, aggression, and coercive sexual behavior. As predicted, insecure childhood attachment, especially insecure paternal attachment, was associated with antisociality, aggression, and coercive sexual behavior. Moreover, childhood attachment independently predicted coercive sexual behavior after antisociality and aggression were statistically controlled. The hypothesis that paternal avoidant attachment would predict coercive sexual behavior independently of its relationship with aggression and antisociality was also supported. Posthoc analysis indicated that maternal anxious attachment was associated with antisociality and that paternal avoidant attachment was associated with both antisociality and coercive sexual behavior. These results are consistent with criminological and psychological research linking adverse early family experiences with offending and lend support to an attachment-theoretical framework for understanding offending behavior in general and sexual offending behavior in particular.

    Implanting testosterone (T) subcutaneously over Postnatal Days 5-20 masculinized sexual behavior, reduced proceptive responsiveness, and shifted sexual preference more readily in male than in female ferrets gonadectomized on Day 5. This enhanced sensitivity of males to neonatal T was best duplicated in females exposed transplacentally to T over Embryonic Days (E) 27-39 (41-day gestation) and injected at birth with T (2.5 micrograms sc in oil: 10% ethanol). Extended exposure of male ferrets to high levels of T, beginning shortly after the onset of testicular steroidogenesis (E25) and continuing for several hours after birth (E41) normally sensitizes their brains to the subsequent organizational effects on coital performance and sexual motivation of the relatively low levels of T that circulate in male ferrets during the first 3 postnatal weeks.

    The present study investigated 1) the importance of the aromatization process during the perinatal period for the development of the sexually dimorphic nucleus in the preoptic area of the hypothalamus (SDN-POA) of male rats, and 2) the relationship between SDN-POA volume and parameters of masculinization in male rats that were treated perinatally with the aromatase-inhibitor ATD. Males were treated with ATD either prenatally or pre- and neonatally, or with the vehicle. Masculine sexual behavior and partner preference were investigated in adulthood. Thereafter, animals were sacrificed and SDN-POA volume was measured. The SDN-POA volume was reduced in both the prenatally and the pre- and neonatally treated group, with a larger reduction in the latter than in the former group. Combined pre- and neonatal ATD treatment resulted in reduced frequency of mounts, intromissions, and ejaculations, as well as a reduced preference for a female over a male. The SDN-POA size was significantly and positively correlated with frequency of masculine sexual behavior, as well as preference for a female over a male.

  16. Sexual behavior of mares.

    Crowell-Davis, Sharon L

    2007-06-01

    The mare is seasonally polyestrus, having an anovulatory period during the short light days of late fall and early winter, and beginning to ovulate as the days become longer during the winter. The complete estrus cycle is typically about 3 weeks, with 5 to 7 days of estrus and approximately 2 weeks of diestrus. When a mare lives within the natural social structure of the horse, i.e. a family band with several adult mares and one or more stallions, estrus is characterized by repeatedly approaching the stallion, frequent urination, deviating the tail away from the perineum, and standing still with the hind limbs spread apart. Diestrus is characterized by avoidance of an approaching stallion, and aggression toward the stallion, such as squealing, striking, and kicking, if he persists in attempting to court the diestrus mare. However, mares and stallions with long-term social relationships will often rest together, graze together and groom each other, all without sexual interactions. Hormonally, estrous behavior in the mare is initiated by estradiol that is secreted by the follicle, while estrous behavior is suppressed by progesterone, secreted by the corpus luteum. Mares are unusual among the ungulates in that they periodically exhibit estrous behavior during the anovulatory period. This is probably due to the release of estrogenic steroids secreted by the adrenal cortex. The display of sexual behavior by the mare throughout the year is thought to facilitate maintenance of the horse's social structure, in which the male remains with a group of females year round, in contrast with most ungulates in which the females and males only come together during the mating season.

    A large-scale, community-based survey was done to assess the frequency of a wide variety of sexual behaviors in normal preadolescent children and to measure the relationship of these behaviors to age, gender, and socioeconomic and family variables. A sample of 880 2- through 12-year-old children screened to exclude those with a history of sexual abuse were rated by their mothers using several questionnaire measures. The frequency of different behaviors varied widely, with more aggressive sexual behaviors and behaviors imitative of adults being rare. Older children (both boys and girls) were less sexual than younger children. Sexuality was found to be related to the level of general behavior problems, as measured by the Achenbach Internalizing and Externalizing T scores and to a measure of family nudity. It was not related to socioeconomic variables. PMID:1881723

    To better understand temporal trends in sexual behavior and their determinants, it is important to look at the demographic and technologic context in which we live; both affect sexual behaviors. Mental disorders and CSA emerge as important correlates of high-risk sexual behaviors. The changing role and expectations of women-the result of major economic and social transformation-transform society further through changes to family and community structures. These changes occur alongside increasing inequality and upheavals in the world, all of which are more visible through increased mobility and communication in the "global village." Changes in sexual norms, relationships, abuse, and mental health are better understood in the context of this broad political background. PMID:15963873

    Background: Sex is a complex, important and sensitive issue in human being and interwoven with the whole of human existence. Given the serious changes in attitude, function and behavior in sex, the need to address sexual function, especially sexual satisfaction, is felt completely. Sexual satisfaction has a very important role in creating marital satisfaction and any defect in sexual satisfaction is significantly associated with risky sexual behaviors, serious mental illness, social crimes and ultimately divorce. Aim: The aim of this study was to explore affecting factors on sexual satisfaction in women based on an overview in scientific database. Methods: In this narrative review the researchers searched MEDLINE database, Google Scholar and Science Direct as well as Persian database like Scientific Information Database with search terms of sexual satisfaction and sexual function, restricted to English/ Persian language, during the 20 years ago. Then those articles written by renowned experts were selected. In this regard, 57 articles have been reviewed, which 30 articles related to this research have been extracted. Results: The findings were divided in to four categories including: Demographic factors, Pathophysiological factors, Psychological factors and Sociocultural factors. Conclusions: Sexuality, especially sexual intimacy is sophisticated and yet elegant affair that the other persons has different definitions and different functions. Discrepancies in the results of the studies show that analysis of factors affecting sexual satisfaction regardless of the women’s’ sociocultural context, religious beliefs, and personal attitudes is undoubtedly inefficient, unscientific and irrational.

    Although the idea that sexuality is a lifelong need is gaining greater research support and greater acceptability to the general public, few consider the institutionalized aged as having sexual needs or being able to benefit from sexual intimacy. The research presented here indicates that sexual activity in the institutionalized aged is related to their attitudes and behavior toward sexuality and to their sexual interest level and prior frequency of sexual activity. Institutionalized aged persons evidence sexual needs and do engage in sexual behavior.

    A high reproductive potential is one reason for the rapid spread of Drosophila suzukii in Europe and in the United States. In order to identify mechanisms that mediate mating and reproduction in D. suzukii we studied the fly's reproductive behavior, diurnal mating activity and sexual maturation. Furthermore, we studied the change of female cuticular hydrocarbons (CHCs) with age and conducted a preliminary investigation on the role of female-derived chemical signals in male mating behavior. Sexual behavior in D. suzukii is characterized by distinct elements of male courtship leading to female acceptance for mating. Time of day and age modulate D. suzukii mating activity. As with other drosophilids, female sexual maturity is paralleled by a quantitative increase in CHCs. Neither female CHCs nor other olfactory signals were required to induce male courtship, however, presence of those signals significantly increased male sexual behavior. With this pilot study we hope to stimulate research on the reproductive biology of D. suzukii, which is relevant for the development of pest management tools.

    Published research demonstrates an association between exposure to media sexual content and a variety of sex-related outcomes for adolescents. What is not known is the mechanism through which sexual content produces this "media effect" on adolescent beliefs, attitudes, and behavior. Using the Integrative Model of Behavioral Prediction, this article uses data from a longitudinal study of adolescents ages 16 to 18 (N = 460) to determine how exposure to sexual media content influences sexual behavior. Path analysis and structural equation modeling demonstrated that intention to engage in sexual intercourse is determined by a combination of attitudes, normative pressure, and self-efficacy but that exposure to sexual media content only affects normative pressure beliefs. By applying the Integrative Model, we are able to identify which beliefs are influenced by exposure to media sex and improve the ability of health educators, researchers, and others to design effective messages for health communication campaigns and messages pertaining to adolescents' engaging in sexual intercourse.

    The sequential separation of male and female function in flowers of dichogamous species allows for the evolution of differing morphologies that maximize fitness through seed siring and seed set. We examined staminate- and pistillate-phase flowers of protandrous Saponaria officinalis for dimorphism in floral traits and their effects on pollinator attraction and seed set. Pistillate-phase flowers have larger petals, greater mass, and are pinker in color, but due to a shape change, pistillate-phase flowers have smaller corolla diameters than staminate-phase flowers. There was no difference in nectar volume or sugar content one day after anthesis, and minimal evidence for UV nectar guide patterns in staminate- and pistillate-phase flowers. When presented with choice arrays, pollinators discriminated against pistillate-phase flowers based on their pink color. Finally, in an experimental garden, in 2012 there was a negative correlation between seed set of an open-pollinated, emasculated flower and pinkness (as measured by reflectance spectrometry) of a pistillate-phase flower on the same plant in plots covered with shade cloth. In 2013, clones of genotypes chosen from the 2012 plants that produced pinker flowers had lower seed set than those from genotypes with paler flowers. Lower seed set of pink genotypes was found in open-pollinated and hand-pollinated flowers, indicating the lower seed set might be due to other differences between pink and pale genotypes in addition to pollinator discrimination against pink flowers. In conclusion, staminate- and pistillate-phase flowers of S. officinalis are dimorphic in shape and color. Pollinators discriminate among flowers based on these differences, and individuals whose pistillate-phase flowers are most different in color from their staminate-phase flowers make fewer seeds. We suggest morphological studies of the two sex phases in dichogamous, hermaphroditic species can contribute to understanding the evolution of sexual

    Doramectin (DOR) is an antiparasitic drug that is widely used in domestic animals. In mammals, DOR acts as a γ-aminobutyric acid receptor agonist. This neurotransmitter plays an important role in the regulation of sexual behavior. The present study investigated the effects of two medically relevant doses of DOR on sexual behavior in male rats. We also examined whether previous sexual experience modulates responses to DOR. General activity was first observed in an open field 24, 48, and 72 h after administration of 0.1 and 0.3 mg/kg DOR to determine the dose and time effects of the drug. Apomorphine-induced penile erection and sexual behavior in inexperienced male rats were then analyzed. The effects of previous sexual experience on subsequent sexual behavior in DOR-treated rats (0.3 mg/kg, 24 h prior to the test) were also assessed. The standard therapeutic dose (0.2 mg/kg) did not modify general activity or penile erection. A slightly concentrated dose of 0.3 mg/kg, which is still within the therapeutic range, decreased apomorphine-induced penile erection, whereas 0.2 mg/kg did not modify this behavior. Compared with controls, sexual behavior in inexperienced male rats was impaired after 0.3 mg/kg DOR. Previous sexual experience had little impact on the effects of 0.3 mg/kg DOR. In conclusion, the 0.2 mg/kg dose of DOR did not affect motor behavior or apomorphine-induced penile erection. At a more slightly higher dose level, the appetitive and consummatory phases of sexual behavior in inexperienced male rats were impaired. Previous sexual experience was unable to reverse this sexual impairment, suggesting that previous sexual experience does not exert a positive effect in attenuating sexual impairment produced by DOR treatment.

    Although having a sexual victimization history is associated with engaging in sexual risk behavior, the mechanisms whereby sexual victimization increases risk behavior are unclear. This study examined use of sex as an affect regulation strategy as a mediator of the relationship between depressive symptoms and sexual risk behavior among 1,616 sexually active college women as well as examined having a history of child sexual abuse (CSA), adolescent/adult sexual assault (ASA), or both (CSA/ASA) as moderators. Results supported the mediated model as well as moderated mediation, where depressive symptoms were more strongly associated with use of sex as an affect regulation strategy among ASA victims, and sex as an affect regulation strategy was more strongly related to sexual risk behavior for CSA/ASA victims.

    Sexual coercion may affect the sexual experiences of sexual minority women differently. Women (n=445) aged 18 to 71 years (Mean=30.38) answered an online survey on sexual orientation, lifetime coercion, and sexual history. Sexual minority women (45.8%, n=204) were more likely to report having been coerced into unwanted sexual behavior (56.5%) than heterosexual women (44.8 %; p=0.010). Coerced sexual minority women reported earlier ages of initiation into performing oral sex (p=0.016), penile-vaginal (p=0.024), and penile-anal (p=0.027) intercourse. In multiple logistic regression models, currently being in a partnered relationship was the sole factor related to lifetime engagement in penile-vaginal intercourse and receiving oral sex from partners. Having at least a graduate degree was the only characteristic related to engagement in lifetime penile-anal intercourse. Sexual coercion was not related to any lifetime sexual behavior outcomes. The nature of sexual initiation and coercion should be explored further among sexual minority women, with the goal of incorporating their experiences into prevention and treatment initiatives.

Coerced sexual minority women reported earlier ages of initiation into performing oral sex (p=0.016), penile-vaginal (p=0.024), and penile-anal (p=0.027) intercourse. In multiple logistic regression models, currently being in a partnered relationship was the sole factor related to lifetime engagement in penile-vaginal intercourse and receiving oral sex from partners. Having at least a graduate degree was the only characteristic related to engagement in lifetime penile-anal intercourse. Sexual coercion was not related to any lifetime sexual behavior outcomes. The nature of sexual initiation and coercion should be explored further among sexual minority women, with the goal of incorporating their experiences into prevention and treatment initiatives.

    The cultural compatibility of sexually related instruments is problematic because the contexts from which the concepts and meanings were extracted may be significantly different from related contexts in a different society. This paper describes the instruments that have been used to assess sexual behaviors, primarily in Western contexts. Then, based on the instruments’ working definition of ‘sexual behavior’ and their theoretical frameworks, we will (1) discuss the applicability or cultural compatibility of existing instruments targeting women's sexual behaviors within an Iranian context, and (2) suggest criteria for sexually related tools applicable in Iranian settings. Iranian women's sexual scripts may compromise the existing instruments’ compatibility. Suggested criteria are as follows: understanding, language of sexuality, ethics and morality. Therefore, developing a culturally comprehensive measure that can adequately examine Iranian women's sexual behaviors is needed. PMID:25250346

    Some sexual behaviors are related to child sexual abuse experiences, but none unequivocally. Therefore, professionals might use non-empirical-based criteria and be biased when detecting and reporting victims. To check this hypothesis, we presented 974 Spanish and Latin American professionals from different fields (Psychology, Education, Health, Social Services, Justice, and Police Force) with hypothetical situations of child sexual behavior (varying the sex, age and behavior) by using an experimental vignette method based on Factorial Survey. Participants were asked to indicate whether such behaviors are a sign of abuse and whether they would report them. We also measured demographic, academic, professional and attitude factors. According to the analysis, professionals' suspicion of abuse is more affected by personal factors, whereas their reporting intention depends more on situational factors. The main criterion adopted is the type of sexual behavior, with professionals being more likely to suspect and report in response to aggressive sexual behavior and precocious sexual knowledge. Professionals' attitudes to sexuality seem to generate biases, as those who are erotophobic are more likely to suspect abuse. None of the sexual behaviors was seen as evidence of abuse.

    In a meta-analysis on controlled outcomes evaluations of 22,000 sex offenders, Losel and Schmucker found 80 comparisons between treatment and control groups. The recidivism rate averaged 19% in treated groups, and 27% in controls. Most other reviews reported a lower rate of sexual recidivism in treated sexual offenders. Of 2039 citations in this study (including literature in five languages), 60 studies held independent comparisons. Problematic issues included the control groups; various hormonal, surgical, cognitive behavioral, and psychotherapeutic treatments; and sample sizes. In the 80 studies compared after the year 2000, 32% were reported after 2000, 45% originated in the United States, 45% were reported in journals, and 36% were unpublished. Treatment characteristics showed a significant lack of pharmacologic treatment (7.5%), whereas use cognitive and classical behavioral therapy was 64%. In 68% of the studies, no information was available on the integrity of the treatment implementation; 36% of the treatment settings were outpatient only, 31% were prison settings, and 12% were mixed settings (prison, hospital, and outpatient). Integrating research interpretations is complicated by the heterogeneity of sex offenders, with only 56% being adult men and 17.5% adolescents. Offense types reported included 74% child molestation, 48% incest, and 30% exhibitionism. Pedophilia was not singled out. Follow-up periods varied from 12 months to greater than 84 months. The definition of recidivism ran the gamut from arrest (24%), conviction (30%), charges (19%), and no indication (16%). Results were difficult to interpret because of the methodological problems with this type of study. Overall, a positive outcome was noted with sex offender treatment. Cognitive-behavioral and hormonal treatment were the most promising. Voluntary treatment led to a slightly better outcome than mandatory participation. When accounting for a low base rate of sexual recidivism, the reduction

    SUMMARY Sex hormones such as estrogen and testosterone are essential for sexually dimorphic behaviors in vertebrates. However, the hormone-activated molecular mechanisms that control the development and function of the underlying neural circuits remain poorly defined. We have identified numerous sexually dimorphic gene expression patterns in the adult mouse hypothalamus and amygdala. We find that adult sex hormones regulate these expression patterns in a sex-specific, regionally-restricted manner, suggesting that these genes regulate sex typical behaviors. Indeed, we find that mice with targeted disruptions of each of four of these genes (Brs3, Cckar, Irs4, Sytl4) exhibit extremely specific deficits in sex specific behaviors, with single genes controlling the pattern or extent of male sexual behavior, male aggression, maternal behavior, or female sexual behavior. Taken together, our findings demonstrate that various components of sexually dimorphic behaviors are governed by separable genetic programs. PMID:22304924

    Several clades of spiders whose females evolved giant sizes are known for extreme sexual behaviors such as sexual cannibalism, opportunistic mating, mate-binding, genital mutilation, plugging, and emasculation. However, these behaviors have only been tested in a handful of size dimorphic spiders. Here, we bring another lineage into the picture by reporting on sexual behavior of Darwin's bark spider, Caerostris darwini. This sexually size dimorphic Madagascan species is known for extreme web gigantism and for producing the world's toughest biomaterial. Our field and laboratory study uncovers a rich sexual repertoire that predictably involves cannibalism, genital mutilation, male preference for teneral females, and emasculation. Surprisingly, C. darwini males engage in oral sexual encounters, rarely reported outside mammals. Irrespective of female's age or mating status males salivate onto female genitalia pre-, during, and post-copulation. While its adaptive significance is elusive, oral sexual contact in spiders may signal male quality or reduce sperm competition. PMID:27126507

    Background: Infertility is a reproductive health problem and its prevalence is increasing in developing countries. This problem has some significant effects on the sexual behaviors of infertile women, especially during infertility treatment periods. Discovering the existing beliefs in the field of sexual and reproductive health and also determining the misconceptions would define the educational needs for providing sexual health programs for infertile women. Women should be able to distinguish risky behaviors from healthy behaviors that falsely have been marked as infertility-related behaviors. This qualitative study was conducted to determine women's beliefs about infertility and sexual behaviors among Iranian infertile women. Materials and Methods: The present study was a qualitative conventional content analysis study conducted on 15 infertile women and 8 key informants until reaching data saturation. Guba and Lincoln evaluative criteria were used for ensuring rigor of the study. Results: Data analysis defined three classes of beliefs that directly or indirectly affected sexual behaviors in infertile women: 1) Cultural, religious, or ethnic beliefs, 2) believing in the effect of diet on infertility, and 3) effect of the type of intercourse on getting pregnant. Conclusions: Three themes of religious, cultural, and ethnic beliefs, believing in the effect of diet on infertility, and the effect of the type of intercourse were the most important factors indicating sexual behaviors among infertile women. It seems that cultural and social matters are the most effective factors on sexual behaviors of infertile Iranian women. PMID:27563321

    Sexual scripts are widely shared gender and culture-specific guides for sexual behavior with important implications for HIV prevention. Although several qualitative studies document how sexual scripts may influence sexual risk behaviors, quantitative investigations of sexual scripts in the context of sexual risk are rare. This mixed methods study involved the qualitative development and quantitative testing of the Sexual Scripts Scale (SSS). Study 1 included qualitative semi-structured interviews with 30 Black heterosexual men about sexual experiences with main and casual sex partners to develop the SSS. Study 2 included a quantitative test of the SSS with 526 predominantly low-income Black heterosexual men. A factor analysis of the SSS resulted in a 34-item, seven-factor solution that explained 68% of the variance. The subscales and coefficient alphas were: Romantic Intimacy Scripts (α = .86), Condom Scripts (α = .82), Alcohol Scripts (α = .83), Sexual Initiation Scripts (α = .79), Media Sexual Socialization Scripts (α = .84), Marijuana Scripts (α = .85), and Sexual Experimentation Scripts (α = .84). Among men who reported a main partner (n = 401), higher Alcohol Scripts, Media Sexual Socialization Scripts, and Marijuana Scripts scores, and lower Condom Scripts scores were related to more sexual risk behavior. Among men who reported at least one casual partner (n = 238), higher Romantic Intimacy Scripts, Sexual Initiation Scripts, and Media Sexual Socialization Scripts, and lower Condom Scripts scores were related to higher sexual risk. The SSS may have considerable utility for future research on Black heterosexual men’s HIV risk. PMID:24311105

    Sexual abuse is a problem of epidemic proportions in the United States. Given the scope of the problem of sexual abuse and the amount of media attention it receives, it is not unusual for parents or caretakers who witness a child exhibiting sexual behavior to become alarmed. Primary care providers, including pediatric nurse practitioners, may be the first professional parents contact with concerns regarding a child's sexual behavior. It is imperative that primary care providers understand childhood sexuality and respond appropriately when confronted with child sexual behaviors in their practice. Although the literature includes little research on the subject of normal child sexual development, certain guidelines have been identified to describe normal child sexual behaviors and those of concern. Case studies illustrate the response of two primary care providers when they are confronted with sexual behaviors in their patients. Implications for practice are discussed, with examples and guidelines provided for primary care providers to use when evaluating sexual behavior in their pediatric patients. PMID:15007288

    Feeding adult rats with high fat (HF) diets can alter their hypothalamic pituitary adrenal (HPA) axis responsiveness. In the present study, we examined the effect of a high fat diet, applied in rats from weaning to puberty, on their behavior and HPA axis status at puberty onset. Wistar rats of both sexes were fed postweaning with two diets containing either 24% fat (high fat, HF) or 4.3% fat (normal chow) by weight. HF enhanced puberty onset in female rats, without increasing body weight gain in either sex, compared with chow-fed animals. In the forced swim test, HF males exhibited a more active behavioral response on the first day, whereas HF females a more passive response during the second day of the test, as compared with their chow-fed counterparts. In the open field test, HF females showed increased sniffing but reduced rearing, compared with chow-fed females and were less explorative than HF males in the central arena. All animals could learn and recall a water maze task though HF males spent more time in the opposite quadrant than chow-fed males during memory test. The HPA axis status of these animals was investigated under basal conditions. Pubertal fat-fed males had lighter adrenals, while females heavier ones, compared with their counterparts. In addition, plasma corticosterone levels of female rats were increased and glucocorticoid receptor levels in their hypothalamus were reduced due to fat diet, while in males no such changes were detected. We conclude that HF feeding during the prepubertal period can affect behavior and the HPA axis of rats at puberty onset, well before the appearance of the obese state, in a sexually dimorphic manner. Fat diet impacted more the female HPA axis, suggesting that their system is more sensitive to fat-induced nutritional imbalance during adolescence. Present data suggest that the fat-induced nutritional imbalance in young females may lead to neuroendocrine dysfunction that in turn may trigger the appearance of stress

    Homeless youth commonly report engaging in sexual risk behaviors. These vulnerable young people also frequently report being sexually victimized. This systematic review collates, summarizes, and appraises published studies of youth investigating relationships between homelessness, perpetration of sexual offenses, experience of sexual victimization, and engagement in sexual risk behavior. A systematic search of seventeen psychology, health, and social science electronic databases was conducted. Search terms included "homeless*," "youth," "offend*," "victimization," "crime," "rape," "victim*," and "sex crimes." Thirty-eight studies were identified that met the inclusion criteria. Findings showed homeless youth commonly report being raped and sexually assaulted, fear being sexually victimized, and engage in street prostitution and survival sex. Rates of victimization and sexual risk behavior were generally higher for females. Given the paucity of longitudinal studies and limitations of current studies, it is unclear whether homelessness is prospectively associated with sexual victimization or engagement in sexual risk behavior, and whether such associations vary cross nationally and as a function of time and place. Future prospective research examining the influence of the situational context of homelessness is necessary to develop a better understanding of how homelessness influences the perpetration of sexual offenses, experience of sexual victimization, and engagement in sexual risk behavior among homeless youth.

    AID's prevention efforts can benefit from taking into account 5 main aspects (KEPRA) of community structure identified by anthropologists: 1) kinship patterns, 2) economics, 3) politics, 4) religion, and 5) associations. For example, in Uganda among the Basoga and paternal aunt or senga is responsible for female sex education. Such culturally determined patterns need to be targeted in order to enhance education and effectiveness. Economics can reflect differing systems of family support through sexual means. The example given involves a poor family with a teenager in Thailand who exchanges a water buffalo or basic necessity for this daughter's prostitution. Politics must be considered because every society identifies people who have the power to persuade, influence, exchange resources, coerce, or in some way get people to do what is wanted. Utilizing these resources whether its ministers of health, factory owners, or peers is exemplified in the Monterey, Mexico factor floor supervisor and canteen worker introducing to workers the hows and whys of a new AID's education program. His peer status will command more respect than the director with direct authority. Religious beliefs have explanations for causes of sickness or disease, or provide instruction in sex practices. The example given is of a health workers in Uganda discussing AIDS with rural women by saying that we all know that disease and deaths are caused by spells. "But not AIDS - slim. AIDS is different." Associations can help provide educational, economic, and emotional assistance to the AID's effort or families affected.

    Background There has been increased attention for the need to reduce stigma related to sexual behaviors among gay men and other men who have sex with men (MSM) as part of comprehensive human immunodeficiency virus (HIV) prevention and treatment programming. However, most studies focused on measuring and mitigating stigma have been in high-income settings, challenging the ability to characterize the transferability of these findings because of lack of consistent metrics across settings. Objective The objective of these analyses is to describe the prevalence of sexual behavior stigma in the United States, and to compare the prevalence of sexual behavior stigma between MSM in Southern and Western Africa and in the United States using consistent metrics. Methods The same 13 sexual behavior stigma items were administered in face-to-face interviews to 4285 MSM recruited in multiple studies from 2013 to 2016 from 7 Sub-Saharan African countries and to 2590 MSM from the 2015 American Men’s Internet Survey (AMIS), an anonymous Web-based behavioral survey. We limited the study sample to men who reported anal sex with a man at least once in the past 12 months and men who were aged 18 years and older. Unadjusted and adjusted prevalence ratios were used to compare the prevalence of stigma between groups. Results Within the United States, prevalence of sexual behavior stigma did not vary substantially by race/ethnicity or geographic region except in a few instances. Feeling afraid to seek health care, avoiding health care, feeling like police refused to protect, being blackmailed, and being raped were more commonly reported in rural versus urban settings in the United States (P<.05 for all). In the United States, West Africa, and Southern Africa, MSM reported verbal harassment as the most common form of stigma. Disclosure of same-sex practices to family members increased prevalence of reported stigma from family members within all geographic settings (P<.001 for all). After

    2014-01-01

    In this review, first a historical perspective of serotonin’s (5-HT) involvement in female sexual behavior is presented. Then an overview of studies implicating 5-HT is presented. The effect of drugs that increase or decrease CNS levels of 5-HT is reviewed. Evidence is presented that drugs which increase 5-HT have negative effects on female sexual behavior while a decrease in 5-HT is associated with facilitation of sexual behavior. Studies with compounds that act on 5-HT1, 5-HT2 or 5-HT3 receptors are discussed. Most evidence indicates that 5-HT1A receptor agonists inhibit sexual behavior while 5-HT2 or 5-HT3 receptors may exert a positive influence. There is substantial evidence to support a role for 5-HT in the modulation of female consummatory sexual behavior, but studies on the role of 5-HT in other elements of female sexual behavior (e.g. desire, motivation, sexual appetite) are few. Future studies should be directed at determining if these additional components of female sexual behavior are also modulated by 5-HT. PMID:24239784

Age, marital status, education, income, drinking alcohol, length of stay away from home, knowledge about transmission and prevention of HIV, and HIV-prone behavior of truck drivers were studied. Chi-square, mean, and SD were calculated. In all, 289 (97.6%) drivers had heard about HIV/AIDS. Only 242 (81.8%) were aware of HIV transmission by heterosexual route. Misconceptions such as HIV transmission by mosquito bites, living in same room, shaking hands, and sharing food were found. Out of 174 (58.8%) who visited Commercial Sex Workers (CSW), 146 (83.9%) used a condom. 38 (12.8%) visited more than 5 CSW in the last 3 months. Time away from home on the road, marital status, alcohol use, and income class were associated with visiting CSW. High-risk behavior was established in the study population. Safe sex and use of condoms need to be promoted among the truck drivers and better condom availability needs to be assured on highways.

    With the improvement of quality life in the elderly of technologically developed countries, sexuality has become an important aspect of aging. In the elderly there is a progressive decline of organic functions; the decrease of sexual and procreating activity is linked with the impaired male hormonal production. The four stages of sexual function are modified: 1. delayed erection; 2. plateau prolongation; 3. orgasm modifications; 4. fast penis detumescence. In addition to organic impairment, aesthetic, social, environmental and psychological factors can restrict sexual activity, as well as past sexual experiences and co-morbidity. There are specific aspects concerning sexuality in the elderly, such as the increased chances of public relations and emotional involvement, the more intense psychic activity and the stronger process of removal and sublimation of impulses. In conclusion the best way to deal with sexuality in the elderly is the multidimensional assessment. PMID:8252083

    The present study evaluated the effects of methamphetamine (MA) on sexual behavior in female rats. In Experiment 1, ovariectomized, hormone-primed rats were injected with MA (1.0mg/kg, i.p.) or saline prior to a test for mate choice wherein females could mate with two males simultaneously. Female rats treated with saline returned to their preferred mate faster after receiving intromissions and visited their preferred mate at a higher rate than their non-preferred mate. In contrast, MA-treated female rats spent a similar amount of time with their preferred and non-preferred mate and failed to return to their preferred mate faster than to their non-preferred mate following intromissions. Two weeks later, the females received the same drug treatment but were tested for partner preference wherein females could spend time near a male or female stimulus rat. All subjects spent more time near the male stimulus than the female stimulus. However, the MA-treated rats visited the male stimulus more frequently and spent less time near the female stimulus than the saline-treated rats. Similar to Experiment 1, female rats in Experiment 2 were tested for mate choice and then two weeks later tested for partner preference; however, females received three daily injections of MA (1.0mg/kg, i.p.) or saline. Females treated chronically with MA returned to both males faster following intromissions than females treated with saline, independent of preference (i.e., preferred mate and non-preferred mate). Furthermore, MA-treated rats were more likely to leave either male (i.e., preferred or non-preferred mate) than saline-treated rats after receiving sexual stimulation. Although MA-treated subjects spent more time near the male stimulus than the female stimulus, they spent less time near either when compared to saline-treated subjects. The present results demonstrate that MA affects sexual behavior in female rats partly by increasing locomotion and partly by directly affecting sexual

    Background: Infertility makes an essential challenge to the sexual life of couples, especially infertile women. When pregnancy does not happen, infertile women think that sexual intercourse is not fruitful and sexual desire became reduce gradually. Infertile women progressively forget that their sexual relationship is also a response to their natural need. Objective: This qualitative study was conducted to explore the infertility consequences in the sexual behavior of infertile women. Materials and Methods: This was a qualitative content analysis study; and it was part of a widespread study, used a sequential mixed-method and conducted from August 2014 until February 2015. A purposeful sampling was used to recruit infertile women who had referred to Yazd Research and Clinical Center for Infertility. Data gathering techniques employed in this research included in-depth semi structured open face-to-face interviews and field notes. Credibility, transferability, confirm ability, and dependability were assessed for the rigor of the data collection. Results: Totally, 15 infertile women and 8 key informants were interviewed. Data analysis showed four themes about impact of infertility on female sexual behavior: 1/ Impact of infertility drugs on couple sexual behavior, 2/ Impact of assisted reproductive technologies on female sexual behavior, 3/ Timed intercourse during infertility and 4/ The psychological impact of infertility on sexual behavior. Conclusion: Some of Iranian infertile women could cope with their problems, but some of them were very affected by infertility drugs and assisted reproductive technologies procedures. Psychosexual counseling before medical treatment could help them to have a better sexual life. PMID:26644793

A Somali-born bilingual interviewer conducted the semistructured interviews in English or Somali; 22 participants chose to be interviewed in Somali. Interviews were translated, transcribed, and analyzed using descriptive statistics and thematic analyses. Our study findings highlighted a sexually conservative culture that values sexual intimacy, female and male sexual pleasure, and privacy in marriage; vaginal sexual intercourse as the only sanctioned sexual behavior; and the importance of Islamic religion in guiding sexual practices. Findings related to human immunodeficiency virus (HIV) revealed HIV testing at immigration, mixed attitudes toward condom use, and moderate knowledge about HIV transmission modes. Female genital cutting (FGC) was a pervasive factor affecting sexual functioning in Somali women, with attitudes about the controversial practice in transition. We recommend that health professionals take the initiative to discuss sexual health care and safer sex, sexual behaviors/functioning, and likely challenges to sexual health with Somali women--as they may be unlikely to broach these subjects without permission and considerable encouragement.

    Studies concerning behaviorally bisexual men continue to focus on understanding sexual risk in according to a narrow range of sexual behaviors. Few studies have explored the subjective meanings and experiences related to bisexual men’s sexual behaviors with both male and female partners. In-depth, semi-structured interviews were conducted with 75 men who engaged in bisexual behavior within the past six months. Participants were asked about their subjective sexual experiences with male and female partners. Findings suggest adherence to normative gender roles, with attraction to men and women conforming to these stereotypes, as well as a segregation of sexual behaviors along gendered lines. Overall, condom use was influenced by perceptions of potential negative consequences. Based on these findings, it remains critical that public health and other social and behavioral sciences continue to study bisexual men’s sexual health issues as separate and distinct from their exclusively homosexual and heterosexual counterparts.

    It is not well understood how infection with HIV and prior experience of sexual violence affects sexual behavior in African women. We describe factors influencing current sexual practices of Rwandan women living with or without HIV/AIDS. By design, 75% of participants were HIV positive and ~50% reported having experienced genocidal rape. Univariate and multivariate logistic regression models were fit to describe demographic and clinical characteristics that influenced sexual behavior in the previous 6 months, condom use, history of transactional sex, and prior infection with a non-HIV sexually transmitted disease. Respondents’ age, where they lived, whether or not they lived with a husband or partner, experience of sexual trauma, CD4 count, CES-D and PTSD scores were strongly associated with risky sexual behavior and infection with non-HIV STI. HIV positive women with a history of sexual violence in the contexts of war and conflict may be susceptible to some high-risk sexual behaviors. PMID:25488169

    This study had three goals: first, to investigate whether sexually explicit Internet material (SEIM) affects sexual risk behavior; second, to study whether these effects differ between adolescents and adults; and third, to analyze, separately for adolescents and adults, whether gender and age moderate an influence of SEIM on sexual risk behavior. The authors conducted a 2-wave panel survey among nationally representative random samples of 1,445 Dutch adolescents and 833 Dutch adults. SEIM use increased sexual risk behavior among adults, but not among adolescents. More specifically, moderator analyses showed that SEIM use increased sexual risk behavior only among male adults, but not among female adults. In the adolescent sample, no moderating gender effect occurred. Neither among adolescents nor among adults did age moderate the effects. Our study shows that SEIM may influence outcomes related to people's sexual health. It also suggests that male adults may present a potential risk group for adverse effects of SEIM. PMID:21476164

    Although adolescents are at disproportionate risk for sexually transmitted infections, most sex education programs have shown little effect on sexual behavior. An interactive video intervention developed by our team has been identified as one of a few programs that have been documented to reduce sexually transmitted infections in this population. Building on behavioral decision research, we used a mental models approach to interview young women about their sexual decisions, finding, among other things, the strong role of perceived social norms. We based our intervention on these results, aiming to help young women identify and implement personally and socially acceptable decision strategies. A randomized controlled trial found that the video reduced risky sexual behavior and the acquisition of chlamydia infection. We recently revised the video to suit more diverse audiences, and upgraded it to modern standards of cinematography and interactivity. It is now in field trial.

    Obesity and unintended pregnancy differentially affect women based on sociodemographic factors. Because of the overlap of these factors, obesity and unintended pregnancy have been described as colliding epidemics. Understanding the relationship between obesity and unintended pregnancy, contraceptive use, and sexual behavior is important in improving the reproductive health of women given the increasing weight demographic. A review of the literature reveals contraceptive use versus nonuse does not differ in women of different body weights. Obese women use oral contraceptives less than normal weight women and are more likely to use procedural methods like sterilization. No difference was noted in most types of sexual behavior for women of different body weights.

    The aim of this study is to describe some characteristics of the sexual behavior of adolescents in Spain and to compare these characteristics according to gender, using a cross-sectional survey. Participants were 1.279 male and female adolescents who reported having had sexual intercourse. A questionnaire about sexual behavior was applied at their high schools and during school hours. Data were collected between 2006 and 2007. Mean age at the onset of sexual intercourse was 14.8 years in males and 15.0 years in females. Males and females were different according to the type of partner at the last sexual intercourse: 63.0% of males had a steady partner compared to 90.5% of females (p < 0.01). The mean number of sexual partners during the last 12 months was higher in males than in females (M = 2.1 and M = 1.5 partners, for males and females, respectively, p < 0.01). 50.0% of males had sexual intercourse under the effects of drugs versus 39.3% of females (p < 0.01). STD and HIV prevention programs should be designed considering the differences according to adolescents' sex.

    The aim of this study was to describe some characteristics of vaginal, anal and oral sexual behavior in Spanish adolescents. It was a cross-sectional descriptive population study conducted using a probabilistic sample survey. The sample was composed of 4,612 male and female adolescents, of whom 1,686 reported having penetrative sexual experience. Sample size was established with a 97% confidence level and a 3% estimation error. Data collection took place in secondary education schools. Mean age of vaginal sex initiation was 15 years. Compared to females, males reported an earlier age of anal and oral sex initiation and a larger number of vaginal and anal sexual partners. Males also reported a higher frequency of penetrative sexual relations under the influence of alcohol or other drugs. A higher percentage of females than males reported not using a condom in their first anal sexual experience. This study provides a current overview of the sexual behavior of adolescents that can be useful for the design of future programs aimed at preventing HIV and sexually transmitted infections (STIs).

    Male-to-female transgender persons are thought to be "vectors" for HIV/STI transmission, yet little quantitative information exists about the risk behavior of their male sexual partners who may serve as a "bridge" for HIV transmission into the general population. As part of an online survey examining the sexual risk behavior of Latino men who have sex with men (N = 1,026), we identified 44 (4%) participants who reported having had sex with a transgender partner. Compared with a randomly selected sub-sample of 200 men who did not report sex with a transgender person, sexual partners of transgender persons were almost three times more likely to have had unprotected sexual intercourse in the last three months. In addition, men who had sex with transgender persons were more likely to be HIV-positive; married, separated, or divorced; identify as bisexual or straight; have sex with women; and live in rural or small town communities. Regression analysis revealed that community size, sexual compulsivity, and having had a transgender partner were independent predictors of unprotected sex. Among Latino men who have sex with men, men with a history of sex with a transgender person appear more likely to be sexually compulsive and at greater risk for HIV and other sexually transmitted infections. These men may, therefore, also serve as a "bridge" for HIV transmission to (as opposed to from) the transgender population.

  16. Sexual motivation--an inquiry into events determining the occurrence of sexual behavior.

    PubMed

    Agmo, A

    1999-11-01

    For the individual engaged in it, sexual behavior has no finality or purpose other than its own execution. Data are presented showing that the execution of sexual reflexes can promote learning, i.e. it functions as reinforcement. Furthermore, positive affect is generated. Based on these principles, a model of sexual motivation has been elaborated. The conceptual framework is the incentive motivation theory previously proposed by Bindra D, A motivational view of learning, performance, and behavior modification, Psychol Rev 1974: 81:199-213; A Theory of Intelligent Behavior, New York: Wiley, 1976; How adaptive behavior is produced: a perceptual-motivational alternative to response reinforcement, Behav Brain Sci 1978; 1:41-52. Although the model is intended for application to most mammals, the rat is used as example. Essentially, sexual approach behaviors are activated by appropriate incentives (conditioned in the male, unconditioned in the female). Approach is, in the inexperienced male, followed by the execution of copulatory reflexes as a consequence of accidentally obtained tactile stimulation of the perineal region. In the female, copulatory acts are activated by tactile stimulation of the flanks and hinds provided by the mounting male. The role of conditioning for the execution of copulatory reflexes and for the acquisition of incentive value of neutral stimuli is analyzed. It is also shown that the incentive properties of sexual acts are not substantially different from those of other incentives. Sexual exhaustion is suggested to be either a case of negative alliesthesia or of stimulus habituation and the Coolidge effect is, in consequence, an example of dishabituation. Studies in women and men support this proposal. It is emphasized that sexual behavior is best understood as being entirely mechanistic albeit not deterministic.

    The relationship between facial expression and experienced affect presents many problems. The two diametrically opposed positions proposing solutions to this problem are exemplified using the conceptions of Mandler u. Izard. The underlying premises of both conceptions still prevail in various forms. The authors reject the concepts according to which facial expression is merely correlated to the affects (see Mandler 1975) as well as the view that facial expression controls the affects (see Izard 1977). The relationship between affect and facial expression is reexamined, subjecting it to a semiotic, essentially semantic analysis similar to the Ogden and Richards' language and meaning approach. This analysis involves a critical discussion of Scherer's attempt of a purely communicational interpretation using Bühler's organon model. In the author's approach, facial expression is seen not simply as a system of signals, but as a system of representative signs which signify the affects and refer to the emotive meaning of things for the subject. The authors develop the thesis that human beings are not born simply with the ability to speak, but also with the abstract possibility of performing facial expressions. This ability develops by way of coordinating patterns of expressions, which are presumably phylogenetically determined, with affects that take on a socially determined individual form, similar to language acquisition during socialisation. The authors discuss the methodological implications arising for studies investigating the affective meaning of facial expressions. PMID:9632951

    The past few years have seen an increased awareness of the relevance of studying the role of sexual response, emotion, and traits such as sensation seeking and the propensity for sexual inhibition in risky sexual behavior. The current study examined the association between self-reported sexual risk taking and psychophysiological response patterns in 76 heterosexual and homosexual men. Measures included genital, electrodermal, startle eyeblink, and cardiovascular responses, and stimuli included threatening (depicting coercive sexual interactions) and nonthreatening (depicting consensual sexual interactions) sexual film excerpts. Sexual risk taking was hypothesized to be associated with decreased inhibition of sexual arousal and hyporeactive affective and autonomic responses to threatening sexual stimuli. Controlling for age and number of sexual partners in the past year, sexual risk taking (number of partners during the past 3 years with whom no condoms were used) was found to be associated with stronger genital responses and smaller eyeblink responses to both threatening and nonthreatening sexual stimuli. Correlations between genital and subjective sexual arousal were relatively low. Sexual risk taking was related to sensation seeking but not to the propensity for sexual inhibition. The findings suggest that risky sexual behavior may involve a role for psychophysiological mechanisms that are specific to sex as well as for ones that are associated with more general approach/avoidance response tendencies.

    The purpose of the present study was to examine the relationship between college women's sexual victimization experiences, health risk behaviors, and sexual functioning. A sample of 309 college women at a mid-sized Midwestern university completed measures assessing sexual victimization, sexual risk taking, substance use behaviors, sexual desire, sexual functioning, prior sexual experiences, and social desirability. Severity of sexual victimization was measured using a multi-item, behaviorally specific, gender-neutral measure, which was divided into four categories based on severity (none, sexual contact, sexual coercion, rape). Within the sample, 72.8% (n = 225) of women reported at least one experience of sexual victimization since age 16. Results from MANCOVAs and a multinomial logistic regression, controlling for social desirability and prior sexual experience, revealed that sexual victimization among female students was related to increased drug use, problematic drinking behaviors, sexual risk taking, sexual dysfunction, and dyadic sexual desire. In addition, findings indicated that women exposed to more severe forms of sexual victimization (i.e., rape) were most likely to report these risk-taking behaviors and sexual functioning issues. Implications for sexual assault risk reduction programming and treatment are discussed.

  1. Positive urgency predicts illegal drug use and risky sexual behavior.

    2009-06-01

    There are several different personality traits that dispose individuals to engage in rash action. One such trait is positive urgency: the tendency to act rashly when experiencing extremely positive affect. This trait may be relevant for college student risky behavior, because it appears that a great deal of college student risky behavior is undertaken during periods of intensely positive mood states. To test this possibility, the authors conducted a longitudinal study designed to predict increases in risky sexual behavior and illegal drug use over the course of the first year of college (n=407). In a well-fitting structural model, positive urgency predicted increases in illegal drug use and risky sexual behavior, even after controlling for time 1 (T1) involvement in both risky behaviors, biological sex, and T1 scores on four other personality dispositions to rash action. The authors discuss the theoretical and practical implications of this finding. PMID:19586152

    Sexual sadism and psychopathy have been theoretically, clinically, and empirically linked to violence. Although both constructs are linked to predatory violence, few studies have sought to explore the covariation of the two constructs, and even fewer have sought to conceptualize the similarities of violence prediction in each. The current study considered all four Psychopathy Checklist-Revised (PCL-R) facets and employed well-defined, validated measures of sadism to elucidate the relation between sadism and psychopathy, as well as to determine the role of each in the prediction of non-sexual violence and sexual crime behaviors. Study 1 assessed 314 adult, male sex offenders using archival ratings, as well as the self-report Multidimensional Inventory of Development, Sex, and Aggression (the MIDSA). Study 2 used archival ratings to assess 599 adult, male sex offenders. Exploratory and confirmatory factor analyses of crime scene descriptions yielded four sexual crime behavior factors: Violence, Physical Control, Sexual Behavior, and Paraphilic. Sadism and psychopathy covaried, but were not coextensive; sadism correlated with Total PCL-R, Facet 1, and Facet 4 scores. The constructs predicted all non-sexual violence measures, but predicted different sexual crime behavior factors. The PCL-R facets collectively predicted the Violence and Paraphilic factors, whereas sadism only predicted the Violence factor.

  4. Sexual differentiation of the brain and behavior.

    PubMed

    2007-09-01

    During the intrauterine period the human brain develops in the male direction via direct action of a boy's testosterone, and in the female direction through the absence of this hormone in a girl. During this time, gender identity (the feeling of being a man or a woman), sexual orientation, and other behaviors are programmed. As sexual differentiation of the genitals takes places in the first 2 months of pregnancy, and sexual differentiation of the brain starts during the second half of pregnancy, these two processes may be influenced independently of each other, resulting in transsexuality. This also means that in the case of an ambiguous gender at birth, the degree of masculinization of the genitals may not reflect the same degree of masculinization of the brain. Differences in brain structures and brain functions have been found that are related to sexual orientation and gender.

  6. Gender and the organization of sexual behavior.

    Tiefer, L; Kring, B

    1995-03-01

    Gender socialization seems important in every culture although the precise nature of gender categories and the specifics of gender roles differ across societies. Gender socialization produces in most people a compulsion to behave according to appropriate rules and expectations, and a grave anxiety about not being considered by others, or by themselves, truly male or female. Sexual performance is tightly tied to appropriate gender role behavior, and the need to conform to conventional scripts probably inhibits most people from expressing individual desires and interests. The gratification obtained from gender affirmation, however, may compensate for any lost erotic or intimate rewards. Our society is in the throes of major changes in gender roles, and many of the frequent public debates about sexual issues (e.g., impact of pornography, prevalence of sexual abuse and harassment, advisability of public sex education, propriety of homosexuals in the military) reflect insecurities about the effect of these new roles on sexual behavior. Present knowledge suggests that any change in gender roles is bound to have a major effect on sexual behavior, both within the life of an individual and within a society. Insecurities and adjustment difficulties are likely to remain normative, and to be part of the problems brought to every mental health clinician. PMID:7761305

    Many antiepileptic drugs (AEDs) produce sexual impairments. Of commonly prescribed AEDs, primidone produces the greatest impairments. Here we examined the effects of primidone on male rat sexual behavior. Sexually-experienced male rats received administration of either vehicle or primidone. After baseline measures were obtained, the effects of daily primidone treatment on home cage sexual performance were assessed three times over the course of 14 days. Motor activity and sucrose preference were also assessed during this time period. Results indicate that primidone impaired copulation but not sexual motivation. Specifically, animals receiving primidone displayed fewer ejaculations, required more time to achieve an intromission, and displayed fewer intromissions per attempted mount as evidenced by a lower intromission ratio. However, animals treated with primidone also chose a goal box containing a sexually-receptive female in an x-maze as often as animals receiving vehicle. The lower intromission ratio suggests an inability to achieve intromissions perhaps as a result of impaired erectile function. Primidone did not affect motor activity or sucrose consumption, an additional measure of natural reward. Together, these data indicate that primidone impairs male sexual activity and suggest that these impairments result primarily from changes in erectile function and not changes to mechanisms mediating motivation.

    High school students today have high ambitions but do not always make choices that maximize their likelihood of educational success. This is the motivation for investigating relationships between high school sexual behavior and two important academic attainment milestones: earning a high school diploma and enrollment in distinct postsecondary programs. Analysis of data from 7,915 National Education Longitudinal Study of 1988–1994 participants indicates that timing of sexual initiation, contraceptive nonuse, and parenthood all predict female and male students’ academic attainment. Furthermore, sexual behavior has more ramifications as attainment milestones become more competitive. These findings point to the importance of considering how students’ choices across multiple life domains influence academic attainment, an important predictor of adult socioeconomic opportunity.

    2010-02-01

    Much research has been conducted on ethnic differences in sexuality, but few studies have systematically assessed the importance of acculturation in sexual behavior. The present study assessed general differences in normative sexual practices in healthy Euro-American, Asian, and Hispanic populations, using measures of acculturation to analyze the relative effects of heritage and mainstream cultures within each group. A total of 1,419 undergraduates (67% Euro-American, 17% Hispanic, 16% Asian; 33% men, 67% women) completed questionnaires which assessed sexual experience and causal sexual behaviors. In concordance with previous studies, Asians reported more conservative levels of sexual experience and frequency of sexual behaviors, fewer lifetime partners, and later ages of sexual debut than Euro-American or Hispanic counterparts. Hispanic reported sexual experiences similar to that of Euro-Americans. There was a significant interaction between mainstream and heritage acculturation in predicting number of lifetime sexual partners in Asian women such that the relationship between heritage acculturation and casual sexual behavior was stronger at lower levels of mainstream acculturation. On the other hand, in Hispanic men, higher levels of mainstream acculturation predicted more casual sexual behavior (one-time sexual encounters and number of lifetime sexual partners) when heritage acculturation was low but less casual sexual behavior when heritage acculturation was high. These results suggest that, for sexual behavior, Hispanic men follow an "ethnogenesis" model of acculturation while Asian women follow an "assimilation" model of acculturation.

    1984-01-01

    As part of a longitudinal study of the sociosexual development of black preadolescents, sexual maturation and sociosexual behaviors were assessed and the relationships between these variables determined in a sample of 101 nine- to eleven-year-old middle- and low-income boys and girls. Sexual maturation was measured by Tanner's staging criteria of specific secondary sex characteristics. Involvement in heterosexual behaviors was elicited via self reports and was classified on a five-point heterosexual physical activity scale (HPA). The data corroborate other studies in demonstrating that girls were more advanced than boys in the process of sexual maturation. Considerable variation in stages of maturation for chronological age existed in both boys and girls, but was more pronounced for girls. In girls, there was no significant association between HPA and degree of biologic maturation. However, genital development in boys was significantly related to their sexual behavior. Income level was not significantly associated with the HPA score. A baseline from which to chart the progress of sociosexual behaviors in these developing preadolescents was established.

  16. Characteristics of Sexual Abuse in Childhood and Adolescence Influence Sexual Risk Behavior in Adulthood

    2006-01-01

    Childhood and adolescent sexual abuse has been associated with subsequent (adult) sexual risk behavior, but the effects of force and type of sexual abuse on sexual behavior outcomes have been less well-studied. The present study investigated the associations between sexual abuse characteristics and later sexual risk behavior, and explored whether gender of the child/adolescent moderated these relations. Patients attending an STD clinic completed a computerized survey that assessed history of sexual abuse as well as lifetime and current sexual behavior. Participants were considered sexually abused if they reported a sexual experience (1) before age 13 with someone 5 or more years older, (2) between the ages of 13 and 16 with someone 10 or more years older, or (3) before the age of 17 involving force or coercion. Participants who were sexually abused were further categorized based on two abuse characteristics, namely, use of penetration and force. Analyses included 1177 participants (n=534 women; n=643 men). Those who reported sexual abuse involving penetration and/or force reported more adult sexual risk behavior, including the number of lifetime partners and number of previous STD diagnoses, than those who were not sexually abused and those who were abused without force or penetration. There were no significant differences in sexual risk behavior between nonabused participants and those who reported sexual abuse without force and without penetration. Gender of the child/adolescent moderated the association between sexual abuse characteristics and adult sexual risk behavior; for men, sexual abuse with force and penetration was associated with the greatest number of episodes of sex trading, whereas for women, those who were abused with penetration, regardless of whether the abuse involved force, reported the most episodes of sex trading. These findings indicate that more severe sexual abuse is associated with riskier adult sexual behavior. PMID:17192833

  17. Review: neuroestrogen regulation of socio-sexual behavior of males

    PubMed Central

    Ubuka, Takayoshi; Tsutsui, Kazuyoshi

    2014-01-01

    It is thought that estrogen (neuroestrogen) synthesized by the action of aromatase in the brain from testosterone activates male socio-sexual behaviors, such as aggression and sexual behavior in birds. We recently found that gonadotropin-inhibitory hormone (GnIH), a hypothalamic neuropeptide, inhibits socio-sexual behaviors of male quail by directly activating aromatase and increasing neuroestrogen synthesis in the preoptic area (POA). The POA is thought to be the most critical site of aromatization and neuroestrogen action for the regulation of socio-sexual behavior of male birds. We concluded that GnIH inhibits socio-sexual behaviors of male quail by increasing neuroestrogen concentration beyond its optimal concentration in the brain for expression of socio-sexual behavior. On the other hand, it has been reported that dopamine and glutamate, which stimulate male socio-sexual behavior in birds and mammals, inhibit the activity of aromatase in the POA. Multiple studies also report that the activity of aromatase or neuroestrogen is negatively correlated with changes in male socio-sexual behavior in fish, birds, and mammals including humans. Here, we review previous studies that investigated the role of neuroestrogen in the regulation of male socio-sexual behavior and reconsider the hypothesis that neuroestrogen activates male socio-sexual behavior in vertebrates. It is considered that basal concentration of neuroestrogen is required for the maintenance of male socio-sexual behavior but higher concentration of neuroestrogen may inhibit male socio-sexual behavior.

    Leclerc, Benoit; Tremblay, Pierre

    2007-03-01

    In this paper, the modus operandi of 103 adolescents involved in sexual offenses against children (12 year old or less) is analyzed. Modus operandi strategies were measured by the participants' responses to the Modus Operandi Questionnaire. Findings indicate that the degree of intrusiveness of the sexual behaviors committed by the adolescents is contingent on the participation of their victims during the sexual episodes. Moreover, the more strategic adolescents may be more likely to secure compliance. This study shows the relevance of analyzing adolescent modus operandi as purposeful behavior and discusses some implications of the findings for crime-commission or offending process models.

    2015-01-01

    Research has shown that gay male couples’ sexual agreements may affect their risk for HIV. Few U.S. studies have collected dyadic data nationally from gay male couples to assess what sexual behaviors they allow to occur by agreement type and the sequence of when certain behaviors occur within their relationships. In our cross-sectional study, dyadic data from a convenience sample of 361 male couples were collected electronically throughout the U.S. by using paid Facebook ads. Findings from our study revealed that couples discussed their HIV status before having UAI, but established their agreement some time after having UAI. About half of the couples (N = 207) concurred about having an agreement. Among these couples, 58% concurred about explicitly discussing their agreement, 84% concurred about having the same type of agreement, and 54% had both men adhering to it. A variety of sexual behaviors were endorsed and varied by agreement type. Concordance about aspects of couples’ agreements varied, suggesting the need to engage couples to be more explicit and detailed when establishing and communicating about their agreements. The allowed behaviors and primary reasons for establishing and breaking sexual agreements further highlight the need to bolster HIV prevention for gay male couples. PMID:23514544

    Most studies of risky sexual behaviors of men who have sex with men (MSM) have been conducted in cities. Few have documented risky sexual behavior of rural men despite increases in rural HIV. Fewer have addressed stigma and risk. This study explored the effects of stigma on sexual risk behavior among rural MSM. We hypothesized that stigma emanating from families, health care providers, and the communities of rural MSM would indirectly affect their sexual risk behavior through their mental health status, specifically self-esteem and internalized homophobia. A convenience sample of 414 rural MSM obtained through political, health service, and social organizations completed an anonymous self-administered questionnaire. Over half of the men reported high-risk sexual behavior. Sensation seeking directly affected levels of sexual risk while the effects of stigma on sexual risk behavior were mediated by mental health variables. Stigma related to respondents' low self-esteem, and low internalized homophobia increased risk behavior.

    Derbyshire, Katherine L.; Grant, Jon E.

    2015-01-01

    Background and Aims Compulsive sexual behavior (CSB) is a common disorder featuring repetitive, intrusive and distressing sexual thoughts, urges and behaviors that negatively affect many aspects of an individual’s life. This article reviews the clinical characteristics of CSB, cognitive aspects of the behaviors, and treatment options. Methods We reviewed the literature regarding the clinical aspects of CSB and treatment approaches. Results The literature review of the clinical aspects of CSB demonstrates that there is likely a substantial heterogeneity within the disorder. In addition, the treatment literature lacks sufficient evidence-based approaches to develop a clear treatment algorithm. Conclusions Although discussed in the psychological literature for years, CSB continues to defy easy categorization within mental health. Further research needs to be completed to understand where CSB falls within the psychiatric nosology. PMID:26014671

  4. Sexual Experience Enhances Drosophila melanogaster Male Mating Behavior and Success

    2014-01-01

    Competition for mates is a wide-spread phenomenon affecting individual reproductive success. The ability of animals to adjust their behaviors in response to changing social environment is important and well documented. Drosophila melanogaster males compete with one another for matings with females and modify their reproductive behaviors based on prior social interactions. However, it remains to be determined how male social experience that culminates in mating with a female impacts subsequent male reproductive behaviors and mating success. Here we show that sexual experience enhances future mating success. Previously mated D. melanogaster males adjust their courtship behaviors and out-compete sexually inexperienced males for copulations. Interestingly, courtship experience alone is not sufficient in providing this competitive advantage, indicating that copulation plays a role in reinforcing this social learning. We also show that females use their sense of hearing to preferentially mate with experienced males when given a choice. Our results demonstrate the ability of previously mated males to learn from their positive sexual experiences and adjust their behaviors to gain a mating advantage. These experienced-based changes in behavior reveal strategies that animals likely use to increase their fecundity in natural competitive environments. PMID:24805129

    Hall, Julie H; Fals-Stewart, William; Fincham, Frank D

    2008-04-01

    The current study explored whether the wives of men entering alcoholism treatment are at risk for sexually transmitted infections (STIs) exposure as a result of their husbands' sexual risk behaviors. The extramarital relationships of married alcoholic men entering outpatient treatment (n = 125) were compared with those of a demographically matched community sample of nonalcoholic married men (n = 125). The proportion of alcoholic men who reported 1 or more extramarital affairs in the previous year (14%) was significantly higher than that of the community sample (4%). Additionally, only 2 alcoholic husbands and 1 nonalcoholic husband reported that his wife was aware of the extramarital relationship. For both groups, none of the men who engaged in extramarital relationships reported consistent use of condoms when having sexual intercourse with their wives or with their extramarital partners. These results suggest that wives of alcoholic men are unknowingly placed at risk for indirect exposure to STIs as a result of their husbands' sexual risk behaviors. Thus, infidelity in treatment-seeking alcohol-abusing men represents a significant public health issue.

  7. Clinical report--the evaluation of sexual behaviors in children.

    PubMed

    Kellogg, Nancy D

    2009-09-01

    Most children will engage in sexual behaviors at some time during childhood. These behaviors may be normal but can be confusing and concerning to parents or disruptive or intrusive to others. Knowledge of age-appropriate sexual behaviors that vary with situational and environmental factors can assist the clinician in differentiating normal sexual behaviors from sexual behavior problems. Most situations that involve sexual behaviors in young children do not require child protective services intervention; for behaviors that are age-appropriate and transient, the pediatrician may provide guidance in supervision and monitoring of the behavior. If the behavior is intrusive, hurtful, and/or age-inappropriate, a more comprehensive assessment is warranted. Some children with sexual behavior problems may reside or have resided in homes characterized by inconsistent parenting, violence, abuse, or neglect and may require more immediate intervention and referrals.

  8. Sexual Differentiation of Behavior in Monkeys: Role of Prenatal Hormones

    Wallen, Kim; Hassett, Janice M.

    2009-01-01

    The theoretical debate over the relative contributions of nature and nurture to sexual differentiation of behavior has increasingly moved towards an interactionist explanation requiring both influences. In practice, however, nature and nurture have often been seen as separable, influencing human clinical sex assignment decisions, sometimes with disastrous consequences. Decisions about sex assignment of children born with intersex conditions have been based almost exclusively on the appearance of the genitals and how other’s reactions to the gender role of the assigned sex affects individual gender socialization. Effects of the social environment and gender expectations in human cultures are ubiquitous, overshadowing potential underlying biological contributions in favor of the more observable social influences. Recent work in nonhuman primates showing behavioral sex differences paralleling human sex differences, including toy preferences, suggests that less easily observed biological factors also influence behavioral sexual differentiation in both monkeys and humans. We review research, including Robert W. Goy’s pioneering work with rhesus monkeys which manipulated prenatal hormones at different gestation times and demonstrated that genital anatomy and specific behaviors are independently sexually differentiated. Such studies demonstrate that for a variety of behaviors, including juvenile mounting and rough play, individuals can have the genitals of one sex but show the behavior more typical of the other sex. We describe another case, infant distress vocalizations, where maternal responsiveness is best accounted for by the mother’s response to the genital appearance of her offspring. Together these studies demonstrate that sexual differentiation arises from complex interactions where anatomical and behavioral biases, produced by hormonal and other biological processes, are shaped by social experience into the behavioral sex differences that distinguish males

    2006-01-01

    This study examines patterns of sexual behavior, sexual relating, and sexual risk among HIV-positive men sexually active with women. A total of 278 HIV-positive men were interviewed every 6–12 months between 1994 and 2002 and reported considerable variability in sexual behaviors over time. Many were not sexually active at all for months at a time; many continued to have multiple female and at times male partners. Over one-third of the cohort had one or more periods when they had engaged in unprotected sex with a female partner who was HIV-negative or status unknown (unsafe sex). Periods of unsafe sex alternated with periods of safer sex. Contextual factors such as partner relations, housing status, active drug use, and recently exchanging sex showed the strongest association with increased odds of unsafe sex. A number of predictors of unsafe sex among African American men were not significant among the Latino sub-population, suggesting race/ethnic differences in factors contributing to heterosexual transmission. Implications for prevention interventions are discussed. PMID:16770702

  11. Subjective and objective measures of attractiveness and their relation to sexual behavior and sexual attitudes in university students.

    Weeden, Jason; Sabini, John

    2007-02-01

    This study examined both self-rated and objectively measured attractiveness in relation to sexual behaviors and attitudes in an undergraduate sample (N=456). About a quarter of the variance in self-ratings of attractiveness was predicted from combining standard objective measures of attractiveness, including face photo ratings, body mass index, and chest-to-waist ratio for men, and face photo ratings, body mass index, and waist-to-hip ratio for women. Correlations were investigated among self-rated attractiveness, measured attractiveness, the residual component of self-rated attractiveness (controlling for measured attractiveness), and a number of sexual and related variables. Measured attractiveness correlated moderately with sexual behaviors but not with sociosexuality or sexual moral attitudes, indicating that higher levels of observable attractiveness may serve to increase opportunities for sex with multiple desirable partners without affecting interests in or moral acceptance of casual sex. Self-rated attractiveness correlated positively with sexual behaviors and with sociosexuality, but the correlation with sociosexuality was based entirely on residual factors beyond the objective measures of attractiveness. Other predictors of sexual behavior were discussed in terms of their variable roles in affecting interest in, opportunities for, and social costs of promiscuous sexual activity. PMID:17136591

    The associations of body piercing with other social characteristics, personality, and sexual behavior were investigated in a population-based sample of young adults, in light of the theory that body piercing has meaning in terms of a corporeal expression of the self. At age 26 years, 966 (95%) of 1019 members of the birth-cohort of the Dunedin Multidisciplinary Health and Development Study were asked about body piercing (at interview) and sexual behavior (questions presented by computer). Assessment of personality traits was conducted at ages 18 or 21 years. In total, 183 participants (9% of the men and 29% of the women) had piercings at a site other than the earlobes. People who lived outside New Zealand or who were of Maori descent were more likely to be pierced, but unemployment and low occupational status were not significantly related to piercing. Women who were pierced, compared with those without piercings, were more likely to have personality traits of low constraint or high negative emotionality. Women with piercings were also more likely to report having had, during the previous year, five or more heterosexual partners (odds ratio, 5.8, 95% CI: 2.3-14.6) or any same-sex partner involving genital contact (odds ratio, 10.3, CI: 2.9-37.2). The associations with sexual behavior in men were weaker and not statistically significant. In this population, body piercing in women was associated with sexual behavior. Having multiple heterosexual partners or any same-sex partner was very rare among women without piercings. The theory of meaning for body piercing was generally supported, offering the possibility of a richer understanding of this phenomenon in the general population.

    2014-01-01

    Receiving more parent sexual communication is generally linked to a later age of first sexual intercourse and less sexual risk taking. However, Asian American youth report minimal parent sexual communication, later sexual initiation, and fewer sexual risks than their counterparts. What contributes to this unexpected pattern of sexual communication and sexual behaviors? To answer this question, we surveyed 312 Asian American college students ages 17 to 22 on their sexual behaviors, parent sexual communication, and peer sexual communication. Assessment of parent and peer sexual communication was completed via a measure in which participants rated the frequency with which they had received each of 22 sexual messages from each source. Young women generally received more messages promoting abstinence, traditional sex roles, and sex within a relational context than their male counterparts. Young men, however, reported greater parent and peer communications that were accepting of casual sex. Exposure to peer messages that were accepting of casual sex was associated with more sexual partners, casual sex encounters, and sexual experience. Being older, being raised outside the United States, being less religious, and being homosexual was each predictive of more sexual experience. Implications regarding the role of culture and gender on sexual socialization are discussed.

    Delta-5 androgen therapies seem to enhance the sexual response in experimental animal models and in clinical trial. This study analyzed the influence of dehydroepiandrosterone (DHEA) administration on receptive and proceptive components of female rat sexual behavior. Ovariectomized (OVX) adult rats were divided in six groups submitted to the following treatments for 4 weeks: DHEA 0.5 and 5 mg/kg, by oral gavage, alone or in combination with estradiol benzoate 3 µg/rat; EB 3 and 10 µg/rat as control groups. All animals received progesterone (500 µg/rat) 4 h before the behavioral tests. All animals were tested for the following: receptivity and proceptivity weekly for 4 weeks; partner preference and paced mating behavior at the end of the treatments. Oral administration of DHEA at 5 mg/kg in EB primed rats was able to significantly increase proceptive behaviors, already after 1 week of treatment. The increase was more marked after 3 and 4 weeks of treatment. Behavioral changes were associated to modifications of circulating and brain level of allopregnanolone and beta-endorphin, although circulating hormonal levels were within a physiological range. Hormonal treatment using physiological doses of delta-5 androgens (DHEA) positively affects sexual motivation in OVX rats.

    A few sexual fatalities show ambiguous or conflicting evidence of manner of death or, in cases involving partners, of the partner's intent. In such equivocal cases, postmortem behavioral analysis and reconstruction aid in understanding what happened and provide an explainable basis for expert judgment and opinion, even though some cases can never be resolved with certainty. Behavioral analysis and reconstruction are enhanced by experience with related cases that have been solved, detailed investigation of the death scene and other relevant settings, and interviews with survivors.

    2013-01-01

    Background Research has demonstrated a consistent relationship between early sexual experience and subsequent sexual risk-taking behaviors. We hypothesized that this relationship is due to a general predisposition towards behavioral disinhibition (BD), and that relationships among BD, early sex, and subsequent risky sexual behavior may be influenced by common genetic influences for males and common environmental influences for females. Methods A prospective sample of 1,512 same-sex adolescent twins (50.2% female) was used. Adolescent BD was measured by clinical symptom counts of conduct disorder, oppositional defiant disorder, and self-reported delinquent behavior (age 14). Age of sexual initiation was defined as first age of consensual oral or penetrative sex (mean age ~17). Adult risky sexual behavior was defined by sexual behaviors under the influence of drugs and alcohol and number of casual sexual partners in the past year (age 24). Results Multivariate analyses showed evidence for substantial common genetic variance among age 14 BD, age at sexual initiation, and adult risky sexual behavior for males, but not females. There was no significant difference in the degree of common environmental influence on these variables for females compared to males. Notably, age of sexual initiation was not significantly correlated with age 24 risky sexual behavior for females. Conclusion The relationship between early sex and later risky sex can be better understood through a general liability towards BD, which is influenced primarily by genetic factors for males. The association between age 14 BD and age of sexual initiation was influenced through a combination of genetic and environmental factors for females; however, age of sexual initiation does not appear to be a salient predictor of adult women’s sexual risk-taking behavior. Findings suggest that prevention programs aimed at reducing sexual risk behavior might target youth exhibiting BD by age 14, particularly males

    Purpose Sexual health refers a state of lifespan well-being related to sexuality. Among young people, sexual health has multiple dimensions, including the positive developmental contributions of sexuality, as well as the acquisition of skills pertinent to avoiding adverse sexual outcomes such as unintended pregnancy and sexually transmitted infections (STIs). Existing efforts to understand sexual health, however, have yet to empirically operationalize a multi-dimensional model of sexual health and to evaluate its association to different sexual/prevention behaviors. Methods Sexual health dimensions and sexual/prevention behaviors were drawn from a larger longitudinal cohort study of sexual relationships among adolescent women (N =387, 14–17 years). Second order latent variable modeling (AMOS/19.0) evaluated the relationship between sexual health and dimensions and analyzed the effect of sexual health to sexual/prevention outcomes. Results All first order latent variables were significant indicators of sexual health (β: 0.192 – 0.874, all p < .001). Greater sexual health was significantly associated with sexual abstinence, as well as with more frequent non-coital and vaginal sex, condom use at last sex, a higher proportion of condom-protected events, use of hormonal or other methods of pregnancy control and absence of STI. All models showed good fit. Conclusions Sexual health is an empirically coherent structure, in which the totality of its dimensions is significantly linked to a wide range of outcomes, including sexual abstinence, condom use and absence of STI. This means that, regardless of a young person’s experiences, sexual health is an important construct for promoting positive sexual development and for primary prevention. PMID:23332488

    2003-06-01

    A large sample of 2-12 year old children (N = 2311) was studied to determine the relationship between three sexually intrusive behavior items (SIBs) measured by the Child Sexual Behavior Inventory (CSBI) and a range of developmental, ecological, and behavioral correlates. The variables studied included age, gender, race, family income, single parent status, maternal education, family sexual behaviors, physical abuse, sexual abuse, domestic violence, social competence of the child, and three scales from the CBCL (Internalizing, Externalizing, and PTSD). Sexual abuse was not the primary predictor of SIB, but a model incorporating family adversity, modeling of coercive behavior, child behavior, and modeling of sexuality predicted a significant amount of variance.

    Sexual self-perceptions are important aspects of sexuality, which can undergo significant change during adolescence and early adulthood. The purpose of this study was to describe these changes among girls (N = 251; ages 16-25) over one year, and to examine associations of sexual self-perceptions (sexual subjectivity) with age, sexual behavior, and romantic status. Sexual body-esteem, perceptions of entitlement to desire and pleasure, sexual efficacy, and sexual self-reflection were investigated as elements of sexual subjectivity. All sexual subjectivity elements were higher among girls who had more sexual experience and/or had steady romantic partners during the study. Perception of entitlement to desire and pleasure increased over time, whereas sexual body-esteem showed the most stability and had minimal associations with sexual or romantic experiences. The greatest increases in sexual subjectivity were found among girls who began the study with the least sociosexual experience and self-reflection also increased for girls who had first coitus after the start of the study. Overall, girls who had sexual intercourse the earliest (before age 16) had the highest sexual subjectivity, but sexual subjectivity increased the most among girls without coital experience or who had more recent first coitus.

  12. Endocrine control of sexual behavior in teleost fish.

    Sexual behavior is one of the most profound events during the life cycle of animals that reproduce sexually. After completion of gonadal development that is mediated by various hormones, oviparous teleosts perform a suite of behaviors, often termed as spawning behavior. This is particularly important for teleosts that have their gametes fertilized externally as the behavior patterns ensures the close proximity of both sexes for gamete release, fusion and ultimately the production of offspring. As in other vertebrates, sexual behavior of fish is also under the control of hormones. Testicular androgen is a requirement for male sexual behavior to occur in most fish species that have been studied. Unlike tetrapods, however, ovarian estrogen does not appear to be essential for the occurrence of female sexual behavior for fish that have their gametes fertilized externally. Prostaglandins produced in the ovary after ovulation act as a trigger in some teleosts to induce female sexual behavior. Potentiating effects of gonadotropin-releasing hormone in the brain on sexual behavior are reported in some species. Under endocrine regulation, male and female fish exhibit gender-typical behavior during spawning, but in some fish species there is also some plasticity in their sexual behavior. Sex changing fish can perform both male-typical and female-typical sexual behaviors during their lifetime and this sexual plasticity can also be observed in non-sex changing fish when undergoing hormonal treatment. Although the neuroanatomical basis is not clear in fish, results of field and laboratory observations suggest that some teleosts possess a sexually bipotential brain which can regulate two types of behaviors unlike most other vertebrates which have a discrete sex differentiation of their brain and can only perform gender-typical sexual behavior.

    Adolescent sexual behavior is multidimensional, yet most studies of the topic use variable-oriented methods that reduce behaviors to a single dimension. In this study, we used a person-oriented approach to model adolescent sexual behavior comprehensively, using data from the National Longitudinal Study of Adolescent Health. We identified five latent classes of adolescent sexual behavior: Abstinent (39%), Oral Sex (10%), Low-Risk (25%), Multi-Partner Normative (12%), and Multi-Partner Early (13%). Membership in riskier classes of sexual behavior was predicted by substance use and depressive symptoms. Class membership was also associated with young adult STI outcomes although these associations differed by gender. Male adolescents' STI rates increased with membership in classes with more risky behaviors whereas females' rates were consistent among all sexually active classes. These findings demonstrate the advantages of examining adolescent sexuality in a way that emphasizes its complexity.

    This study examined the relationship between gender roles and sociosexuality (an individual difference variable describing attitudes about sexual permissiveness and promiscuity), and their predictive pattern of HIV-related sexual risk behaviors. A geographically diverse sample of 275 adult, heterosexual Black women (mean age = 33.60 years), participated in a self-administered survey. Significant relationships were found between feminine traits and sociosexuality, and between sociosexuality and four of the five risky sexual behavior variables. Neither masculine nor feminine gender roles were related to any risky sexual behavior variables. Sociosexuality emerged as an important correlate that requires further exploration of its relationship to the attitudes and behaviors of Black women, and its potential relationship to HIV risk-related sexual behavior. The need for more attention to psychosocial variables, and consideration of context, cultural norms, and values is discussed as an important undertaking in order to garner an accurate picture of sexual risk behavior.

    Children exhibiting sexual behavior have increasingly gained the attention of child welfare and mental health systems, as well as the scientific community. While a heterogeneous group, children with sexual behavior problems consistently demonstrate a number of problems related to adjustment and overall development. In order to appropriately intervene with these children, a comprehensive understanding of etiology is imperative. The overarching goal of the present paper is to review the extant research on mechanisms associated with the development of problematic sexual behavior in childhood within a developmental psychopathology framework. What is known about normative and nonnormative sexual behavior in childhood is reviewed, highlighting definitional challenges and age-related developmental differences. Further, the relationship between child sexual abuse and child sexual behavior problems is discussed, drawing attention to factors impacting this relationship. Risk factors for child sexual behavior problems, beyond that of sexual abuse, are also reviewed utilizing a transactional-ecological framework. Finally, we conclude with a discussion of implications of a developmental psychopathology perspective on problematic child sexual behaviors to inform future research and intervention efforts. Such implications include the need for attention to normative childhood sexual behavior, developmental sensitivity, and examinations of ecological domain in concert.

    2014-01-01

    A robust link between early sexual initiation and sexual risk-taking behavior is reported in previous studies. The relationship may not be causal, however, as the effect of common risk factors is often not considered. The current study examined whether early initiation was a key predictor of risky sexual behavior in the 20s and 30s, over and above co-occurring individual and environmental factors. Data were drawn from the Seattle Social Development Project, a longitudinal panel of 808 youth. Early predictors (ages 10 to 15) and sexual risk taking (ages 21 to 24 and 30 to 33) were assessed prospectively. Early sexual initiation (before age 15) was entered into a series of probit regressions that also included family, neighborhood, peer, and individual risk factors. Although a positive bivariate relation between early sexual initiation and sexual risk taking was observed at both ages, the link did not persist when co-occurring risk factors were included. Behavioral disinhibition and antisocial peer influences emerged as the strongest predictors of sexual risk over and above early sexual initiation. These results suggest that early sexual initiation must be considered in the context of common antecedents; public health policy aimed at delaying sexual intercourse alone is unlikely to substantially reduce sexual risk behavior in young adulthood.

    High rates of adolescent pregnancy, sexually transmitted infections, and unsafe abortions in Nigeria indicate the need for a greater understanding of factors that affect adolescent sexuality. The sexual health needs of adolescents remain poorly known and addressed particularly among vulnerable subpopulations like out-of-school adolescents. The objective of this study was to examine the sexual behavior of female out-of-school adolescents and to identify factors that influence their sexual behavior. This cross-sectional study was conducted among a representative sample of unmarried, out-of-school female adolescents (n = 332, mean age 17 y), selected using cluster sampling, who were working in a major market (Mushin) in Lagos, Nigeria. Data were collected using interviewer administered questionnaires. Many girls (43.7%) have had sexual intercourse. The mean age at initiation was 16 years. The main reason for initiation was curiosity. Risky sexual behavior and transactional sex was common. Nonconsensual sex was also reported. Sexual health knowledge was poor, and friends served as their main source of information on sexual health issues. Factors associated with the initiation of sexual activity were friends sexual behavior, the person adolescents reside with, parents marital status, availability of funds to meet basic needs, and watching pornography (p < .05). Out-of-school female adolescents engaging in risky sexual behavior are exposed to sexual abuse, lack skills to resist pressure, and have limited access to credible reproductive health information. Appropriate interventions including provision of sexuality education and a supportive environment must be instituted to address their needs.

    Sprague-Dawley rats were exposed to the stress of restraint, heat and bright lights three times daily from Days 14 to 22 of gestation. Because prepartal stress did not markedly disturb the mother's retrieving and crouching behavior, disturbances in postpartal nursing behavior do not seem to account for the abnormal sexual behavior of male offspring as adults. The most significant finding was that litter weights were reduced, not only at birth, but for 3 weeks thereafter, suggesting that prepartal stress not only altered the pups in utero but also affected postpartal milk synthesis. The possibility emerges that prepartal stress may alter adult sexual behavior in males by modifications in fetal and/or maternal pituitary glands.

    The term hypersexuality was introduced to describe excessive sexual behavior associated with a person's inability to control his or her sexual behavior. The main aim of the present study was to investigate the impact of different personality traits on the degree of hypersexual behavior as measured by the Hypersexual Behavior Inventory (HBI). A further aim was to evaluate the association between sexual inhibition and excitation [as described in the Dual Control Model (DCM)] and hypersexual behavior. A sample of 1,749 participants completed an internet-based survey comprised the HBI, the short form of the Sexual Inhibition/Sexual Excitation Scales (SIS/SES-SF) as well as more general personality measures: the Behavioral Inhibition System/Behavioral Activation System-scales (BIS/BAS-scales) and a short version of the Big Five Inventory (BFI-10). Using the recommended HBI cut-off, 6.0 % (n = 105) of the present sample could be categorized as hypersexual, which is comparable to the results of previous studies about the prevalence of hypersexual behavior in the general population. The results provided strong support for the components of the DCM-sexual excitation and inhibition-to explain hypersexual behavior, irrespective of gender and sexual orientation. Some of the general personality traits also showed significant relationships with hypersexual behavior. Taken together, the results of the present study provide further support for the relevance of research about the relationships between sexual problems and disorders, the DCM, and personality variables.

    This study examines the effects of different types of sexual expectancies on early sexual behavior among racial/ethnic minority young adolescents. African American and Latino participants between 11 and 13 years old were recruited through schools and community-based agencies in the South Bronx, New York (N = 223). Multiple logistic regression analyses were used to predict early sexual behavior outcomes, which include engagement in sexual possibility situations, kissing, and sexual touching. The moderating effect of gender was examined using multiplicative interaction terms. Higher expectations categorized as personal/parental and romantic/peer expectancies related to the negative consequences of sexual intercourse decreased the odds of engagement in early sexual behavior; whereas higher academic/career and sexual health expectancies did not. Gender moderated the relationships between personal/parental expectancies and engagement in sexual possibility situations and romantic/peer expectancies and kissing. Social workers formulating sexual health promotion and HIV prevention programs for racial/ethnic minority young adolescents should focus on personal/parental and romantic/peer expectancies in favor of negative expectancies regarding academic/career achievement, pregnancy, and HIV. Social work interventions to delay sexual debut should include a family-based component and should be sensitive to gender differences in sexual expectancies. PMID:22461958

    Sexuality education for children and young adults is one of the most heavily debated issues facing policy-makers, national AIDS program planners, and educators, provoking arguments over how explicit education materials should be, how much of it there should be, how often it should be given, and at what age instruction should commence. In this context, the World Health Organization's Global Program on AIDS' Office of Intervention Development and Support commissioned a comprehensive literature review to assess the effects of HIV/AIDS and sexuality education upon young people's sexual behavior. 52 reports culled from a search of 12 literature databases were reviewed. The main purpose of the review is to inform policy-makers, program planners, and educators about the impact of HIV and/or sexuality education upon the sexual behavior of youth as described in the published literature. Of 47 studies which evaluated interventions, 25 reported that HIV/AIDS and sexuality education neither increased nor decreased sexual activity and attendant rates of pregnancy and sexually transmitted diseases (STDs). 17 reported that HIV and/or sexuality education delayed the onset of sexual activity, reduced the number of sex partners, or reduced unplanned pregnancy and STD rates Only 3 studies found increases in sexual behavior associated with sexuality education. Inadequacies in study design, analytic techniques, outcome indicators, and the reporting of statistics are discussed. PMID:12348560

    Previous studies from our laboratory investigated the effects of picrotoxin (PT), a γ-aminobutyric acid receptor antagonist administered during several perinatal periods, on the sexual behavior of male and female rats. We observed that the time of perinatal exposure to PT is critical to determine either facilitation or impairment of sexual behavior. The present study evaluated the effects of prenatal administration of a single dose of PT on gestation day 18 of dams (the first critical period of male brain sexual differentiation) on sexual behavior of male and female offspring. Thus, female Wistar rats were mated with males and, on gestation day 18, received 0.6 mg/kg of PT or 0.9% saline solution subcutaneously. On postnatal day 1, the offspring were weighed and several measures of sexual development were assessed. The sexual behaviors and the general activity in the open field of adult male and ovariectomized, hormone-treated female rats were observed. On comparison with the control group, maternal PT treatment: (i) did not alter the maternal weight, pup weight, anogenital distance, or male and female general activity; (ii) increased female sexual behavior, that is, decreased the latencies to first mount, first lordosis, and tenth lordosis, and the percentage of females presenting lordosis; and (iii) did not alter male sexual behavior. It is suggested that prenatal PT exposure interfered with epigenetic mechanisms related to the development of sex differences in the brain, leading to the observed sexually dimorphic effects on sexual behavior.

    Understanding how demographic processes influence mating systems is important to decode ecological influences on sexual selection in nature. We manipulated sex ratio and density in experimental populations of the sex-role reversed pipefish Syngnathus typhle. We quantified sexual selection using the Bateman gradient (βss'), the opportunity for selection (I), and sexual selection (Is), and the maximum standardized sexual selection differential (smax'). We also measured selection on body length using standardized selection differentials (s') and mating differentials (m'), and tested whether the observed I and Is differ from values obtained by simulating random mating. We found that I, Is, and s'max, but not βss', were higher for females under female than male bias and the opposite for males, but density did not affect these measures. However, higher density decreased sexual selection (m' but not s') on female length, but selection on body length was not affected by sex ratio. Finally, Is but not I was higher than expected from random mating, and only for females under female bias. This study demonstrates that both sex ratio and density affect sexual selection and that disentangling interrelated demographic processes is essential to a more complete understanding of mating behavior and the evolution of mating systems.

  16. Sexual behavior in female western lowland gorillas (Gorilla gorilla gorilla): evidence for sexual competition.

    PubMed

    2009-07-01

    Previous research in gorillas suggests that females engage in post-conception mating as a form of sexual competition designed to improve their own reproductive success. This study focused on sexual behaviors in a newly formed group of western lowland gorillas (Gorilla gorilla gorilla) housed at Zoo Atlanta. All females engaged in mating outside their conceptive periods, although there was individual variation in the frequency of the behavior. An analysis of the presence/absence of sexual behavior found females, regardless of reproductive condition, were more likely to engage in sexual behavior on days when other females were sexually active. On these "co-occurrence" days, females were significantly more likely to solicit the silverback, but copulations did not differ from expectation. The results find further evidence for sexual competition among female gorillas and suggest that this may occur throughout their reproductive cycle rather than only during pregnancy.

    An experience of child sexual abuse (CSA) substantially increases women's risk of adult sexual assault (ASA), but the mechanisms underlying this relationship are unclear. Previous research often has not examined the full range of ASA experiences or included the influence of ethnicity, sexual behavior, and sexual attitudes on CSA and severity of ASA. The current study utilized path analysis to explore the relationships among ethnicity, sexual attitudes, number of lifetime sexual partners, CSA, and severity of ASA in emerging adult women. Results indicated a significant relationship between CSA and more severe ASA that was partially explained by having more lifetime sexual partners. Additionally, European American women, relative to Hispanic women, reported more severe victimization, which was fully explained by more positive attitudes toward casual sex and having more lifetime sexual partners. These results have implications in the design and implementation of universal and selective prevention programs aimed at reducing ASA and revictimization among emerging adult women. PMID:25258422

Previous research often has not examined the full range of ASA experiences or included the influence of ethnicity, sexual behavior, and sexual attitudes on CSA and severity of ASA. The current study utilized path analysis to explore the relationships among ethnicity, sexual attitudes, number of lifetime sexual partners, CSA, and severity of ASA in emerging adult women. Results indicated a significant relationship between CSA and more severe ASA that was partially explained by having more lifetime sexual partners. Additionally, European American women, relative to Hispanic women, reported more severe victimization, which was fully explained by more positive attitudes toward casual sex and having more lifetime sexual partners. These results have implications in the design and implementation of universal and selective prevention programs aimed at reducing ASA and revictimization among emerging adult women.

    A multidimensional measure assessing distinct motivations for and against sex was shown to be reliable, valid, and configurally invariant among incoming first-year college students. Three Motivations Against Sex Questionnaire subscales were developed to measure motivations against sexual behavior (Values, Health, Not Ready) to complement and extend a set of Sexual Motivations Scale-Revised subscales assessing motivations for sexual behavior (Intimacy, Enhancement, Coping). Participants were surveyed the summer prior to college (N = 1,653; 58.4% female). Exploratory factor analysis on a random one quarter of respondents supported the hypothesized factors. Multigroup confirmatory factor analysis demonstrated good overall fit to the data and configural invariance across gender and ethnicity and across lifetime sexual experience. Motivations were associated with lifetime oral and penetrative sexual behaviors. This combined measure may be used for identifying motivations, predicting behaviors, and tailoring motivational interventions for sexual health among adolescents and young adults.

    Data were collected on arrested youths processed at a centralized intake facility, including youths released back to the community and those placed in secure detention. This paper reports the results of a test of a structural model involving newly arrested male and female youths’ sexually transmitted diseases (STD) test results, urine analysis results for recent cocaine and marijuana use, and self-reported engaging in risky sexual behavior. The across gender, multiple group model involved: (1) a confirmatory factor analysis of these variables, reflecting a latent variable labeled Risk, (2) a regression of Risk on the youths’ age, and (3) an examination of the covariance between Risk and the youths’ race and seriousness of arrest charge. Results indicate the youths’ STD status, drug use, and reported risky sexual behavior are interrelated phenomena, similarly experienced across gender. Age was the only correlate of Risk status that demonstrated a significant gender group difference. The youths’ race and seriousness of arrest charges did not significantly affect Risk, regardless of gender. Research and policy implications of the findings are discussed. PMID:21221415

    Objectives Although numerous studies have documented linkages between childhood sexual abuse (CSA) and later sexual revictimization, mechanisms underlying revictimization, particularly assaults occurring in the context of substance use, are not well-understood. Consistent with Traumagenic Dynamics theory, the present study tested a path model positing that lowered perceptions of sexual control resulting from CSA may be associated with increased sex-related alcohol expectancies and heightened likelihood of risky sexual behavior, which in turn, may predict adult substance-related rape. Methods Participants were 546 female college students who completed anonymous surveys regarding CSA and adult rape, perceptions of sexual control, sex-related alcohol expectancies, and likelihood of engaging in risky sexual behavior. Results The data fit the hypothesized model well and all hypothesized path coefficients were significant and in the expected directions. As expected, sex-related alcohol expectancies and likelihood of risky sexual behavior only predicted substance-related rape, not forcible rape. Conclusions Findings suggested that low perceived sexual control stemming from CSA is associated with increased sex-related alcohol expectancies and a higher likelihood of engaging in sexual behavior in the context of alcohol use. In turn these proximal risk factors heighten vulnerability to substance-related rape. Programs which aim to reduce risk for substance-related rape could be improved by addressing expectancies and motivations for risky sexual behavior in the context of substance use. Implications and future directions are discussed. PMID:23312991

    In this study, we investigated attitudes toward sexuality, the prevalence of sexual behaviors and contraceptive use among Chinese medical and nursing undergraduates, and relationships between attitudes toward sexuality and sexual and contraceptive practices among these participants. This was a descriptive, cross-sectional study carried out by using a Personal Attitude toward Sexuality Scale and Sexual and Contraceptive Questionnaire. The participants were recruited in the researcher's lectures. A total of 158 participants joined this study. Overall, Chinese medical and nursing undergraduates in this study held relatively conservative attitudes toward sexuality. The prevalence of sexually-active students was relatively low, and the percentage of contraceptive use among those sexually-active students was also low. Participants' attitudes toward sexuality had statistically-significant effects on their sexual and contraceptive practices. Nearly half of the sexually-active participants reported never using any contraceptive method during sexual intercourse. This finding has important public health implications, as young people represent the group with the largest rate of new infections of HIV/AIDS in China. A more comprehensive sexual education program that extends to college undergraduates and promotes the social acceptability of using contraception, specifically condoms, is needed.

    We examined verbal sexual health communication, pleasure discussions, and physical sexual communication in relation to condom use by young adult, heterosexual Latinos (ages 18-30 years). Participants (N = 220, 51% female) were recruited in a Midwestern state. Verbal sexual health communication was positively associated with consistent condom use among men (odds ratio [OR] = 2.66, p < .05) and women (OR = 3.12, p < .05). For men, pleasure discussions were negatively associated with consistent condom use (OR = 0.21, p < .05). For women, verbal sexual health communication was positively associated with condom use at last sex (OR = 2.75, p < .05), whereas physical sexual communication was negatively associated with condom use at last sex (OR = .29, p < .05). Various aspects of sexual communication may be important in HIV-prevention programs with young Latinos. Physical sexual communication and pleasure discussions, in particular, warrant further exploration given negative relationships with condom use.

    This study aimed to systematically review the articles on factors affecting sexual function during menopause. Searching articles indexed in Pubmed, Science Direct, Iranmedex, EMBASE, Scopus, and Scientific Information Database databases, a total number of 42 studies published between 2003 and 2013 were selected. Age, estrogen deficiency, type of menopause, chronic medical problems, partner's sex problems, severity of menopause symptoms, dystocia history, and health status were the physical factors influencing sexual function of menopausal women. There were conflicting results regarding the amount of androgens, hormonal therapy, exercise/physical activity, and obstetric history. In the mental-emotional area, all studies confirmed the impact of depression and anxiety. Social factors, including smoking, alcohol consumption, the quality of relationship with husband, partner's loyalty, sexual knowledge, access to health care, a history of divorce or the death of a husband, living apart from a spouse, and a negative understanding of women's health were found to affect sexual function; however, there were conflicting results regarding the effects of education, occupation, socioeconomic status, marital duration, and frequency of sexual intercourse.

    Sexual esteem is an integral psychological aspect of sexual health (Snell & Papini, 1989), yet it is unclear if sexual esteem is associated with sexual health behavior among heterosexual men and women. The current analysis uses a normative framework for sexual development (Lefkowitz & Gillen, 2006; Tolman & McClelland, 2011) by examining the association of sexual esteem with sexual behavior, contraception use, and romantic relationship characteristics. Participants (N = 518; 56.0% female; mean age = 18.43 years; 26.8% identified as Hispanic/Latino; among non-Hispanic/Latinos, 27.2% of the full sample identified as European American, 22.4% Asian American, 14.9% African American, and 8.7% multiracial) completed web-based surveys at a large northeastern university. Participants who had oral sex more frequently, recently had more oral and penetrative sex partners (particularly for male participants), and spent more college semesters in romantic relationships, tended to have higher sexual esteem than those who had sex less frequently, with fewer partners, or spent more semesters without romantic partners. Sexually active male emerging adults who never used contraception during recent penetrative sex tended to have higher sexual esteem than those who did use it, whereas female emerging adults who never used contraception tended to have lower sexual esteem than those who did use it. Implications of these results for the development of a healthy sexual self-concept in emerging adulthood are discussed. PMID:25210789

    2014-01-01

    OBJECTIVES: This study aimed to examine the prevalence of sexting behaviors (sexually explicit messages and/or pictures) among an at-risk sample of early adolescents as well as the associations between sexting behaviors and sexual behaviors, risk-related cognitions, and emotional regulation skills. It also aimed to determine whether differences in risk were associated with text-based versus photo-based sexts. METHODS: Seventh-grade adolescents participating in a sexual risk prevention trial for at-risk early adolescents completed a computer-based survey at baseline regarding sexting behavior (having sent sexually explicit messages and/or pictures), sexual activities, intentions to have sex, perceived approval of sexual activity, and emotional regulation skills. RESULTS: Twenty-two percent of the sample reported having sexted in the past 6 months; sexual messages were endorsed by 17% (n = 71), sexual messages and photos by 5% (n = 21). Pictures were endorsed significantly more often by females (χ2[2] = 7.33, P = .03) and Latinos (χ2[2] = 7.27, P = .03). Sexting of any kind was associated with higher rates of engaging in a variety of sexual behaviors, and sending photos was associated with higher rates of sexual activity than sending text messages only. This was true for a range of behaviors from touching genitals over clothes (odds ratio [OR] = 1.98, P = .03) to oral sex (OR = 2.66, P < .01) to vaginal sex (OR = 2.23, P < .01). CONCLUSIONS: Sexting behavior (both photo and text messages) was not uncommon among middle school youth and co-occurred with sexual behavior. These data suggest that phone behaviors, even flirtatious messages, may be an indicator of risk. Clinicians, parents, and health programs should discuss sexting with early adolescents. PMID:24394678

Results Growth trajectories are linear for sexual behavior but not for exposure to sexual media content. The signs of the exposure slopes are not uniformly positive: Hispanic and African-American respondents show declines of exposure to sexual media content over the age range investigated here. Conclusions While changes in exposure to sex content are highly associated with changes in sexual behavior among Whites, there is little or no association between changes in these variables among Blacks.

    Background Previous research has extensively examined the relationship between the use of alcohol and illicit substances with sexual risk behaviors among sexual minority (i.e., gay and bisexual) male youth; however, no known studies have assessed the association of steroid use to risk behaviors among this population. Methods Participants were 556 sexually active sexual minority adolescent boys (M age = 16.2, SD = 1.3), taken from a pooled dataset of the 14 jurisdictions from the 2005 and 2007 Youth Risk Behavior Surveys that assessed sexual orientation. The association between lifetime use of steroids and sexual risk behaviors were examined. Results Controlling for number of sexual partners, depression, victimization, and race, boys who reported increased steroid use were at increased odds of engaging in condomless sex, OR = 1.55, p = .003, and use of alcohol/drugs during sex, OR = 1.48, p = .002. Conclusions Steroid use among sexual minority adolescent boys is prevalent and associated with HIV/STI sexual transmission risk behaviors. PMID:26144592

    Classic and contemporary approaches to the assessment of female sexuality are discussed. General approaches, assessment strategies, and models of female sexuality are organized within the conceptual domains of sexual behaviors, sexual responses (desire, excitement, orgasm, and resolution), and individual differences, including general and sex-specific personality models. Where applicable, important trends and relationships are highlighted in the literature with both existing reports and previously unpublished data. The present conceptual overview highlights areas in sexual assessment and model building that are in need of further research and theoretical clarification. PMID:8543712

    The present study tested associations between common developmental contexts (relationship involvement, independent living, college attendance, work) and risky sexual behavior (casual sex, inconsistent condom use, high-risk sex) across the two years following high school. Data were drawn from the Raising Healthy Children project, and included 801 participants aged 18–21 years. Longitudinal analyses, which controlled for early sexual debut, high school substance use, and high school grades, showed that living with a parent was protective against all three sexual risk behavior outcomes (ORs about 0.70). Being in a romantic relationship was associated with a lower probability of casual sex, but a higher probability of inconsistent condom use. Attending college was associated with a lower probability of high-risk sex (OR = 0.67). Working was not related to the sexual risk behaviors examined. Levels of sexual risk behavior showed little change across the two years following high school. Findings from this study suggest that developmental context may affect young adults’ engagement in risky sexual behavior. Programs aimed at promoting sexual health and reducing risk behaviors for STIs among young adults should consider targeting those in romantic relationships, those not living with parents, and those not attending college. Further, to develop effective prevention programs for these targeted youth, it is critical that we understand the mechanisms leading to risky sex in these groups. PMID:20571863

    Research indicates gender differences in sensitivity to psychomotor stimulants. Preclinical work investigating the interaction between drugs of abuse and sex-specific behaviors, such as sexual behavior, is critical to our understanding of such gender differences in humans. A number of behavioral paradigms can be used to model aspects of human sexual behavior in animal subjects. Although traditional assessment of the reflexive, lordosis posture of the female rat has been used to map the neuroanatomical and neurochemical systems that contribute to uniquely female copulatory behavior, the additional behavioral paradigms discussed in the current review have helped us expand our description of the appetitive and consummatory patterns of sexual behavior in the female rat. Measuring appetitive behavior is particularly important for assessing sexual motivation, the equivalent of "desire" in humans. By investigating the effects of commonly abused drugs on female sexual motivation, we are beginning to elucidate the role of dopaminergic neurotransmission, a neural system also known to be critical to the neurobiology of drug addiction, in female sexual motivation. A better understanding of the nexus of sex and drugs in the female brain will help advance our understanding of motivation in general and explain how psychomotor stimulants affect males and females differently.

    Childhood sexual abuse (CSA) is associated with a wide range of negative outcomes. This study investigated the relation between CSA and sexual risk behavior in 827 patients recruited from an STD clinic. Overall, CSA was reported by 53% of women and 49% of men, and was associated with greater sexual risk behavior, including more sexual partners, unprotected sex, and sex trading. Alcohol use for men, and drug use for women, mediated the relation between CSA and the number of partners in the past three months; intimate partner violence mediated the relation between CSA and the number of episodes of unprotected sex in the past three months for women. These results document the prevalence of CSA among patients seeking care for an STD, and can be used to tailor sexual risk-reduction programs for individuals who were sexually abused. PMID:16881780

    Gaining a healthy sexual attitude and behavior and being able to show appropriate approaches to patients in terms of sexual issues are important acquisitions for medical students. The aim of the present study was to determine, compare, and evaluate the sexual attitudes and behaviors of Dokuz Eylul University Faculty of Medicine students. An anonymous questionnaire was filled in by first- and sixth-year students in order to determine their sexual attitudes and behaviors. While information sources in the adolescence period for both genders were friends in the first place, these sources were mostly mothers, books, newspapers--magazines for females, and newspapers--magazines and television for males. The opinion of males about having sexual intercourse before marriage for males was positive, and females were more tolerant about males having this experience before marriage as compared to females having sexual experience before marriage. Rates of expression of having sexual intercourse and masturbation were found to be higher for male students. The first sexual experience with a sex worker or sentimentally insignificant partner was high among males. In general, the rate of condom use was lower, and the rate of coitus interruptus was found to be higher than in foreign studies. All the students declared 'my own will and values' as the most frequent factor affecting their sexual attitudes and behaviors, and high rates for 'social factors', 'religious requirements', 'the expectations of families', and 'protection from sexually transmitted diseases' were observed. The findings lead to the conclusions that gender differences exist in the sexual attitudes and behaviors of medical students; the enhancing effect of the traditional structure on gender discrimination is still continuing; students are not provided with sufficient scientific approach or training prior to the university education; and beyond biomedical training, they should receive more support in those fields during

  1. Sexual selection affects local extinction and turnover in bird communities

    Predicting extinction risks has become a central goal for conservation and evolutionary biologists interested in population and community dynamics. Several factors have been put forward to explain risks of extinction, including ecological and life history characteristics of individuals. For instance, factors that affect the balance between natality and mortality can have profound effects on population persistence. Sexual selection has been identified as one such factor. Populations under strong sexual selection experience a number of costs ranging from increased predation and parasitism to enhanced sensitivity to environmental and demographic stochasticity. These findings have led to the prediction that local extinction rates should be higher for species/populations with intense sexual selection. We tested this prediction by analyzing the dynamics of natural bird communities at a continental scale over a period of 21 years (1975-1996), using relevant statistical tools. In agreement with the theoretical prediction, we found that sexual selection increased risks of local extinction (dichromatic birds had on average a 23% higher local extinction rate than monochromatic species). However, despite higher local extinction probabilities, the number of dichromatic species did not decrease over the period considered in this study. This pattern was caused by higher local turnover rates of dichromatic species, resulting in relatively stable communities for both groups of species. Our results suggest that these communities function as metacommunities, with frequent local extinctions followed by colonization. Anthropogenic factors impeding dispersal might therefore have a significant impact on the global persistence of sexually selected species.

  2. Do feather-degrading bacteria affect sexually selected plumage color?

    Models of parasite-mediated sexual selection propose that males with more elaborate sexual traits will have fewer parasites. These models have generally been tested using metazoan or protozoan parasites of the blood, gut, or integument. Fewer studies have examined sexual ornaments in relation to bacterial infections. While most surface bacteria are harmless or beneficial, feather-degrading bacteria may have detrimental effects. In this study, we examined the relationships between overall bacterial load, feather-degrading bacterial load, and sexually selected carotenoid-based plumage color in a wild population of house finches ( Carpodacus mexicanus). We found that males with the redder plumage preferred by females had similar overall bacterial loads, but lower feather-degrading bacterial loads, than males with less red plumage. These data suggest that plumage color can signal abundance of feather-degrading bacteria to potential mates. It remains unclear whether feather-degrading bacteria directly or indirectly affect plumage color, but the observed correlations suggest that feather-degrading bacteria may play some role in sexual selection.

    BACKGROUND: This study examines the temporal sequencing of sexting and sexual intercourse and the role of active sexting (sending a nude picture) in mediating the relationship between passive sexting (asking or being asked for a nude picture) and sexual behaviors. METHODS: Data are from Wave 2 (spring 2011) and Wave 3 (spring 2012) of an ongoing 6-year longitudinal study of high school students in southeast Texas. Participants included 964 ethnically diverse adolescents with a mean age of 16.09 years (56% female; 31% African American, 29% Caucasian, 28% Hispanic, 12% other). Retention rate for 1-year follow-up was 93%. Participants self-reported history of sexual activity (intercourse, risky sex) and sexting (sent, asked, been asked). Using path analysis, we examined whether teen sexting at baseline predicted sexual behavior at 1-year follow-up and whether active sexting mediated the relationship between passive sexting and sexual behavior. RESULTS: The odds of being sexually active at Wave 3 were 1.32 times larger for youth who sent a sext at Wave 2, relative to counterparts. However, sexting was not temporally associated with risky sexual behaviors. Consistent with our hypothesis, active sexting at Wave 2 mediated the relationship between asking or being asked for a sext and having sex over the next year. CONCLUSIONS: This study extends cross-sectional literature and supports the notion that sexting fits within the context of adolescent sexual development and may be a viable indicator of adolescent sexual activity.

    Developmentally inappropriate sexual behavior has long been viewed as a possible indicator of child sexual abuse. In recent years, however, the utility of sexualized behavior in forensic assessments of alleged child sexual abuse has been seriously challenged. This article addresses a number of the concerns that have been raised about the…

    Researching the correlates of men's sexually aggressive behavior (i.e., verbal coercion and rape) is critical to both understanding and preventing sexual aggression. This study examined 120 men who completed an anonymous online questionnaire. The study aimed to determine the relative importance of two potential correlates of men's self-reported use of sexual aggression: (a) perceptions that male peers use and support sexual aggression and (b) perceptions of punishment likelihood associated with sexual aggression. Results revealed that perceptions of male friends' acceptance of sexual aggression were strongly associated with individual men's reports of using verbal coercion and rape. Perceptions of punishment likelihood were negatively correlated with verbal coercion but not with rape through intoxication and force. Implications for sexual aggression prevention are discussed.

    Two studies tested whether online social networking technologies influence health behavioral social norms, and in turn, personal health behavioral intentions. In Study 1, experimental participants browsed peers' Facebook photos on a college network with a low prevalence of sexually suggestive content. Participants estimated the percentage of their peers who have sex without condoms, and rated their own future intentions to use condoms. Experimental participants, compared to controls who did not view photos, estimated that a larger percentage of their peers use condoms, and indicated a greater intention to use condoms themselves in the future. In Study 2, participants were randomly assigned to view sexually suggestive or nonsexually suggestive Facebook photos, and responded to sexual risk behavioral questions. Compared to participants viewing nonsuggestive photos, those who viewed sexually suggestive Facebook photos estimated that a larger percentage of their peers have unprotected sexual intercourse and sex with strangers and were more likely to report that they themselves would engage in these behaviors. Thus, online social networks can influence perceptions of the peer prevalence of sexual risk behaviors, and can influence users' own intentions with regard to such behaviors. These studies suggest the potential power of social networks to affect health behaviors by altering perceptions of peer norms.

    2014-01-01

    Youth under 25 show substantial sexual and substance use risk behaviors. One factor associated with risk behaviors is delay discounting, the devaluation of delayed outcomes. This study determined if delay discounting for sexual outcomes is related to sexual risk and substance use among 18–24 year olds. Females (70) and males (56) completed the Sexual Discounting Task, which assessed their likelihood of having unprotected immediate sex vs. waiting for sex with a condom, at various delays, with four hypothetical sexual partners selected from photographs: the person they (1) most wanted to have sex with, (2) least wanted to have sex with, (3) judged most likely to have an STI, and (4) judged least likely to have an STI. They also completed instruments assessing HIV knowledge, sexual behaviors, substance use, risk attitudes, inhibition, impulsivity, and sensation seeking. Condom use likelihood generally decreased with increasing delay. Preference for immediate, unprotected sex was greater for partners whom participants most (vs. least) wanted to have sex with, and judged least (vs. most) likely to have an STI. Preference for immediate, unprotected sex in the 'most want to have sex with' and ‘least likely to have an STI' conditions was related to greater lifetime risky sexual partners, lifetime number of unique substances used, disregard of social approval/danger, disinhibition, and sensation/excitement seeking. Males showed greater likelihood of unprotected sex than females when condom use was un-delayed, but delay affected condom use similarly between sexes. Delay discounting should be considered in strategies to minimize youth risk behavior. PMID:25545764

    The aim of the present study was to investigate the prevalence of not reporting sexual attraction in the past year and its associations with factors related to partner relations as well as sexuality-related characteristics in a population-based sample of Finnish twins. The present study was based on a total of 3,540 participants (1,304 men and 2,236 women) aged 33-43 years. A total of 19 men and 73 women reported complete absence of sexual interest in women or men during the past year. Older age was associated with absence of sexual interest in the past year in women, but not men. Individuals who reported absence of sexual interest in the past year were more likely than individuals who reported sexual interest to be single, but those who were in a relationship did not express more dissatisfaction with their relationships. Individuals who reported absence of sexual interest in the past year had had fewer sexual partners and reported less experience of sexual behavior in childhood. Women who reported no sexual interest in the past year, but who were nevertheless sexually active, reported higher frequencies of sexual dysfunctions than matched controls. No significant differences regarding the tendency to fake orgasm were found between the sexually active individuals who reported absence of sexual interest in the past year and the group of matched controls. The present study suggests that absence of sexual interest may be a lifelong phenomenon which does not necessarily affect relationship satisfaction, but is associated with variation in sexual behaviors.

    Objectives Some individuals experience their first sexual intercourse through physically forced sex, which affects the way they experience and cope with stress. We examined differences in sexual risk behavior, experience of stressors, and use of stress-coping strategies among adolescents in Nigeria based on their history of forced sexual initiation and HIV status. Methods We analyzed data from 436 sexually active 10–19-year-old adolescents recruited through a population-based survey from 12 Nigerian states. Using Lazarus and Folkman’s conceptual framework of stress and coping, we assessed if adolescents who reported forced sexual initiation were more likely to report HIV sexual risk practices, to report as stressors events related to social expectations, medical care and body images, and loss and grief, and to use more avoidance than adaptive coping strategies to manage stress. We also assessed if HIV status affected experience of stressors and use of coping strategies. Results Eighty-one adolescents (18.6%) reported a history of forced sexual initiation; these participants were significantly more likely to report anal sex practices (OR: 5.04; 95% CI: 2.14–11.87), and transactional sex (OR: 2.80; 95% CI: 1.56–4.95). Adolescents with no history of forced sexual initiation were more likely to identify as stressors, life events related to social expectations (OR: 1.03; 95% CI: 0.96–1.11) and loss and grief (OR: 1.34; 95% CI: 0.73–2.65), but not those related to medical care and body images (OR: 0.63; 95% CI: 0.34–1.18). They were also more likely to use adaptive responses (OR: 1.48; 95% CI: 0.62–3.50) than avoidance responses (OR: 0.90; 95% CI: 0.49–1.64) to cope with stress, though these differences were not significant. More adolescents with a history of forced sexual initiation who were HIV positive identified as stressors, life events related to medical care and body images (p = 0.03) and loss and grief (p = 0.009).

    This study assessed early adolescents' attitudes and perceptions regarding nonconsensual sexual activity. A total of 371 surveys (94% return rate) was completed. More than one-third of respondents (35%) reported they had engaged in sexual intercourse; 17% reported having been sexually coerced by a teen-ager; 19% reported feeling pressure from their friends to have intercourse; 7% reported having been sexually coerced by an adult; and 6% reported having sexually coerced someone else. Students also demonstrated lack of knowledge regarding nonconsensual sexual behaviors. Analysis of variance tests determined if knowledge (KN), attitudes (AT), behavioral intentions (BI), and locus of control (LC) changed across specific background and demographic variables. One background variable (having been sexually coerced by a teen-ager) was associated with high risk orientation (lower scores) on all four subscales. Lower scores also were associated with being male (KN, AT, BI), having sexually coerced someone else (KN, AT, BI), having been sexually coerced by an adult (AT, BI), and having engaged in sexual intercourse (AT, BI).

    Involvement of septal nuclei in modulation of male sexual behavior in rats was investigated. Sexually active Wistar male rats were assigned to intact, sham, lateral septal nuclei lesioned (LSL), and medial septal nuclei lesioned (MSL) groups. All male rats were tested for sexual behavior in an arena in the presence of a sexually receptive female. Intromission and ejaculation latencies were increased, and mount, intromission, and ejaculation frequencies were decreased in the LSL group compared to the intact group. In contrast, mount and intromission latencies were decreased, and pursuit and mount frequencies were increased in the MSL group compared to the intact group. The results indicate that medial septal nuclei may inhibit and lateral septal nuclei may facilitate male sexual behavior in rats. PMID:7652045

    Research examining the sexual behaviors and experiences of behaviorally bisexual men is limited. Most studies focus primarily on highlighting sexual risk behaviors among groups of “men who have sex with men (MSM)” or “gay and bisexual men,” which may not be appropriate in terms of behaviorally bisexual men’s sexual repertoires with both men and women. This study aimed to assess a broad range of sexual behaviors and associated experiences among bisexual men living in the midwestern United States. An interviewer-administered questionnaire containing items from the National Survey of Sexual Health and Behavior assessed lifetime and recent (i.e., past six months and last event) sexual behaviors and experiences with both male and female partners among a diverse sample of 75 behaviorally bisexual men. Responses were quantified and analyzed using descriptive and multivariate statistics. A wide range of sexual behaviors with partners of both genders was found. Vaginal intercourse and oral sex with both men and women were the most commonly reported behaviors. Subjective reports of pleasure, arousal, and sexual function during sexual activity were similar with both male and female partners. Many participants reported using condoms during insertive sexual behaviors with male and female partners, but less during oral sex. Unprotected receptive anal sex was less commonly reported. Overall, participants reported a variety of sexual behaviors and experiences; however, unlike other populations, they shared these with partners of both genders. Results have implications for interventions targeting the sexual behaviors and associated issues among behaviorally bisexual men. PMID:22187027

    The sexual behavior of the Arashiyama West troop, a natural semi-free-ranging troop of Japanese macaques, was studied during the 1973-1974 and 1974-1975 breeding seasons. The troop was transported intact from Japan to its current location in South Texas. There they have been free to move about in a 42.2-hectare electric fence enclosure. This report describes the relationships among age, aging, and sexual behavior. Males beginning at the age of 2.5 years were observed to series-mount estrous females in the double foot clasp mount position. Mounting in series in the double foot position is the normal pattern for Japanese macaque males. The ejaculation of semen with concomitant body movements indicative of orgasm begins at age 4.5 years at the earliest and continues until death. Males 4.5 and 5.5 years of age, sexually mature in the physiological sense, were not consistently sexually mature in the behavioral sense. The oldest male displayed traits that appear analogous to traits observed in aging human males. Females begin to experience estrus at 3.5 years of age. However, like pubescent males, pubescent females display behavioral patterns of sexual immaturity. The oldest female of the troop has remained sexually active. The attainment of sexual maturity by adulthood can be viewed as a learned process leading to efficiency and prowess, followed in old age by sexual involution.

    Sexual behavior among older adults with HIV in Sub-Saharan Africa has been understudied despite the burgeoning of this population. We examined sexual behavior among older adults living with HIV in Uganda. Participants were eligible for the study if they were 50 years of age or older and living with HIV. Quantitative data were collected through face-to-face interviews, including demographic characteristics, health, sexual behavior and function, and mental health. Of respondents, 42 were men and 59 women. More than one-quarter of these HIV-positive older adults were sexually active. A greater proportion of older HIV-positive men reported being sexually active compared to women (54 vs. 15%). Among those who are sexually active, a majority never use condoms. Sixty-one percent of men regarded sex as at least somewhat important (42%), while few women shared this opinion (20%). Multivariate logistic regression analyses revealed that odds of sexual activity in the past year were significantly increased by the availability of a partner (married/cohabitating), better physical functioning, and male gender. As more adults live longer with HIV, it is critical to understand their sexual behavior and related psychosocial variables in order to improve prevention efforts.

    Human papillomavirus (HPV) prevalence varies widely worldwide. We used a transmission model to show links between age-specific sexual patterns and HPV vaccination effectiveness. We considered rural India and the United States as examples of 2 heterosexual populations with traditional age-specific sexual behavior and gender-similar age-specific sexual behavior, respectively. We simulated these populations by using age-specific rates of sexual activity and age differences between sexual partners and found that transitions from traditional to gender-similar sexual behavior in women <35 years of age can result in increased (2.6-fold in our study) HPV16 prevalence. Our model shows that reductions in HPV16 prevalence are larger if vaccination occurs in populations before transitions in sexual behavior and that increased risk for HPV infection attributable to transition is preventable by early vaccination. Our study highlights the importance of using time-limited opportunities to introduce HPV vaccination in traditional populations before changes in age-specific sexual patterns occur.

    2014-06-01

    The neurobiological bases of human sexual behavior are only partly understood. The etiology of most human sexual dysfunctions is not understood at all. Nevertheless, substantial progress has been made in the treatment of some male sexual disorders. The prime example should be erectile deficiency, where several efficient and safe treatments are available. Pharmacological treatment for premature ejaculation is also available, although it is still in an early stage. Disorders of sexual desire have attracted much attention when women are affected but far less so when men are concerned. Whereas animal models appropriate for testing treatments for problems with erection and premature ejaculation are available, it is questionable whether such models of the desire disorders have predictive validity. There seems to be many factors involved both in reduced and enhanced sexual desire, most of which are unknown. In this review we present some data suggesting that an electroencephalographic analysis of brain activity during exposure to sexually relevant stimuli in male rats and men and during execution of sexual behaviors in male rats may provide useful information. The effects of a commonly used drug, ethanol, on the electroencephalogram recorded during sexual events in rats and men are also described. Although this approach to the analysis of the central nervous activity associated with sexual desire, arousal and behavior is still in its infancy, the data obtained so far show a remarkable similarity between men and rats. This suggests that animal studies of electroencephalographic responses to drugs in sexual contexts may be useful for predicting effects in the human male.

    2005-02-01

    Because pathogens spread only within the unique context of a sexual union between people when one person is infectious, the other is susceptible to new infection, and condoms are not used to prevent transmission, the epidemiological study of sexually transmitted infections (STIs) is particularly challenging. Social network analysis entails the study of ties among people and how the structure and quality of such ties affect individuals and overall group dynamics. Although ascertaining complete sexual networks is difficult, application of this approach has provided unique insights into the spread of STIs that traditional individual-based epidemiological methods do not capture. This article provides a brief background on the design and assessments of studies of social networks, to illustrate how these methods have been applied to understanding the distribution of STIs, to inform the development of interventions for STI control.

    Repeated social subjugation in early puberty lowers testosterone levels. We used hamsters to investigate the effects of social subjugation on male sexual behavior and metabolic activity within neural systems controlling social and motivational behaviors. Subjugated animals were exposed daily to aggressive adult males in early puberty for postnatal days 28 to 42, while control animals were placed in empty clean cages. On postnatal day 45, they were tested for male sexual behavior in the presence of receptive female. Alternatively, they were tested for mate choice after placement at the base of a Y-maze containing a sexually receptive female in one tip of the maze and an ovariectomized one on the other. Social subjugation did not affect the capacity to mate with receptive females. Although control animals were fast to approach females and preferred ovariectomized individuals, subjugated animals stayed away from them and showed no preference. Cytochrome oxidase activity was reduced within the preoptic area and ventral tegmental area in subjugated hamsters. In addition, the correlation of metabolic activity of these areas with the bed nucleus of the stria terminalis and anterior parietal cortex changed significantly from positive in controls to negative in subjugated animals. These data show that at mid-puberty, while male hamsters are capable of mating, their appetitive sexual behavior is not fully mature and this aspect of male sexual behavior is responsive to social subjugation. Furthermore, metabolic activity and coordination of activity in brain areas related to sexual behavior and motivation was altered by social subjugation. PMID:24852486

    Early initiation of sexual intercourse has been associated with negative consequences, such as higher rates of unwanted pregnancy and HIV infection. This study examined the attitudes and behavior of rural Thai adolescent students aged 16 to 20 years from northern Thailand regarding sexual intercourse. Differences between participants who previously had sexual intercourse and those who had not were explored. Those who had not previously had sexual intercourse were asked about the reasons why they had not had sex, their future plans for having sex and their dating experiences. More than 70% of participants stated they had not previously had sexual intercourse but one third of this group reported engaging in other sexual behavior. There were significant differences by gender, religion, ethnicity, and household income between those who had previously had sex and those who had not. Among those who had not previously had sexual intercourse, concern for their parents' feelings was the most common reason for delaying intercourse. About two-thirds of this group had plans not to have sexual intercourse until after marriage; nearly half of them reported currently having a boyfriend/girlfriend. Interventions aimed at delaying sexual intercourse should involve adolescents in their design and include their attitudes for delaying intercourse. Because of many gender differences seen in our study, interventions should be designed differently for males and females in rural northern Thailand.

    The aim of this study was to investigate whether demographic characteristics and sexual behavior online and offline were associated with private, respectively, nonprivate access to the Internet in a Web sample of people who use the Internet for sexual purposes. A total of 1,913 respondents completed an online questionnaire about Internet sexuality, and 1,614 reported using the Internet for sexual purposes. The majority of these respondents reported having access to an Internet-connected computer no one else had access to (62 percent women and 70 percent men). The results showed that it is possible to differentiate between those who have access to an Internet-connected computer no one else has access to and those who have shared access to an Internet-connected computer. Not only did they differ in demographic characteristics, but also in the sexual activities they engaged in on the Internet. Different patterns were found for women and men. For example, men who had private access to Internet-connected computers were more likely than those who had shared access to seek information about sexual issues. Thus, having access to Internet computers no one else has access to may promote sexual knowledge and health for men. The results of this study along with the technological development implies that in future research, attention should be paid to where and how people access the Internet in relation to online behavior in general and online sexual behavior in particular.

    Objectives. To investigate whether forced sex of men by women was associated with sexual risk behaviors, and whether this association was mediated by substance use. Methods. Data from US men aged 18 years or older at interview in the National Survey of Family Growth 2006–2010 (n = 8108) who reported sexual behavior history. Outcome variables were condom use at most recent sex and number of lifetime sexual partners. Sexual activity covariates included age at first consensual sex and treatment of sexually transmitted infections. Alcohol and drug use were the mediating factors. Results. Six percent of men reported forced sex by a woman at a mean age of 18 years. On average, victimized men had 3 more lifetime sexual partners than nonvictimized men (P < .01). Furthermore, victimized men who reported drug use had, on average, 4 more female sexual partners (P < .01) than nonvictimized men. Marijuana (P < .05) and crack cocaine use (P < .05) partially mediated the association between forced sex and number of female partners. Neither condom use nor number of male partners differed between victimized and nonvictimized men. Conclusions. A nontrivial fraction of men experience forced sex by women; some of them have elevated sexual risk behaviors. PMID:27077345

This article compares sexual risk reports from two self-administered instruments, a standard survey and a sexual health history calendar (SHHC), among racially diverse youth (n = 232) ages 14 to 21 seeking services at a public health clinic. Agreement between methods was assessed using Lin's concordance correlation coefficients (CCC) and Bland-Altman plots. Lin's CCC showed poor to moderate agreement between instruments on reports of sexual partners in the past 3 (0.47), 6 (0.55), and 12 (0.49) months. While individual sexual partner questions were refused a total of 179 times on the survey, youth reported having sexual partners during the same time period on the SHHC in most (77.1%) of these instances. Poor agreement was also found for condom use frequency (CCC = 0.17), with youth's frequency of condom use on the SHHC differing from that reported on the survey for more than half (55.6%) of the months they were sexually active. While lack of objective sexual behavior measures limits conclusions about the accuracy of reports, the ways in which youth's responses varied across instruments may offer insight into the complexity of adolescent sexual risk taking as well as have important implications for development of HIV/STI preventive interventions.

    Purpose Cell phone use has become more widespread over the past decade. Young adults are frequently early adopters of new technologies, including cell phones. Most prior research examining sexting, the act of sending sexually explicit or suggestive images via text message, has focused on the legal or social consequences of this behavior. The current study focused on the public health implications of sexting by examining associations between sexting, substance use, and sexual risk behavior in youth. Methods Young adults (N=763) completed online questionnaires assessing demographics, cell phone use (e.g., texting, sexting), substance use, and sexual risk behaviors. Results Sexting was reported by a substantial minority of participants (44%). Compared to their non-sexting counterparts, participants who engaged in sexting were more likely to report recent substance use and high-risk sexual behaviors, including unprotected sex and sex with multiple partners. Of those who engaged in sexting, a considerable percentage (31.8%) reported having sex with a new partner for the first time after sexting with that person. In multivariate analyses, sexting was associated with high-risk sexual behavior after accounting for demographic factors, total texting behaviors, and substance use. Conclusions Results suggest that sexting is robustly associated with high-risk sexual behavior. Many individuals exchange explicit or provocative photos with long-term sexual partners, but at least some participants in this study were incurring new sexual risks subsequent to sexting. Additional research is needed to understand the contexts in which sexting occurs, motivations for sexting, and relationship of sexting to risk behavior. PMID:23299017

    Young people in secondary schools who are prone to engage in risky sexual behaviors spend considerable time watching Television (TV) which often presents sex scenes. The influence of exposure to sex scenes on TV (SSTV) has been little researched in Nigeria. This study was therefore designed to determine the perceived influence of exposure to SSTV on the sexual behavior of secondary school students in Ibadan North Local Government Area. A total of 489 randomly selected students were surveyed. Mean age of respondents was 14.1 ± 1.9 years and 53.8% were females. About 91% had ever been exposed to sex scenes. The type of TV program from which most respondents reported exposure to sexual scenes was movies (86.9%). Majority reported exposure to all forms of SSTV from secondary storage devices. Students whose TV watching behavior was not monitored had heavier exposures to SSTV compared with those who were. About 56.3% of females and 26.5% of males affirmed that watching SSTV had affected their sexual behavior. Predictor of sex-related activities was exposure to heavy sex scenes. Peer education and school-based programs should include topics to teach young people on how to evaluate presentations of TV programs.

  1. Experience of sexual coercion and risky sexual behavior among Ugandan university students

    2011-01-01

    Background Growing worldwide evidence shows that the experience of sexual coercion is fairly prevalent among young people and is associated with risky sexual behavior thereafter. The causal mechanisms behind this are unclear but may be dependent on specific contextual determinants. Little is known about factors that could buffer the negative effects of coercion. The aim of this study was to assess the association between the experience of sexual coercion and risky sexual behavior among university students of both sexes in Uganda. Methods In 2005, 980 (80%) out of a total of 1,220 students enrolled in Mbarara University of Science and Technology in Uganda participated in a self-administered questionnaire covering socio-demographic and religious factors, social capital, mental health, alcohol use, and sexual behavior. A validated scale of six items was used to assess the experience of sexual coercion. Logistic regression analyses were applied to control for confounders. Potential buffering factors were analyzed by testing for effect modification. Results Fifty-nine percent of those who responded had previously had sexual intercourse. Among the male students 29.0%, and among the female students 33.1% reported having had some experience of sexual coercion. After controlling for age, gender, and educational level of household of origin, role of religion and trust in others sexual coercion was found to be statistically significantly associated with previously had sex (OR 1.6, 95% CI; 1.1-2.3), early sexual debut (OR 2.4, 95% CI; 1.5-3.7), as well as with having had a great number of sexual partners (OR 1.9, 95% CI; 1.2-3.0), but not with inconsistent condom use. Scoring low on an assessment of mental health problems, reporting high trust in others, or stating that religion played a major role in one's family of origin seemed to buffer the negative effect that the experience of sexual coercion had on the likelihood of having many sexual partners. Conclusion The findings

  2. Sexual behavior correlates of female orgasm and marital happiness.

    The present study was designed to investigate sexual behavior correlates of marital happiness and female orgasm. Forty-eight female students of Baylor University who were 20 to 35 years old and had been married at least 2 years participated in the survey. A specially compiled 131-item marital relations questionnaire provided data for an intercorrelational analysis. Marital happiness, fidelity, and experience of orgasm correlated with certain specific sexual behaviors. These variables were related also to dissatisfaction with marital sex, which is consistent with previous research. However, when dissatisfaction resulting from performing less desired sexual acts was separated from dissatisfaction resulting from not performing desired sexual acts, the correlations differed, often markedly. Thus, the data suggest that unitary measures of dissatisfaction with marital sex may obscure meaningful differences. Also, information was obtained concerning the orgasmic and multiple orgasmic experience of the women, their extramartial experience, and their relative use of and preference for various intercourse positions and noncoital sexual activities.

    This survey produced baseline information about student knowledge of sexually transmitted diseases (STDs), their sexual attitudes, and their behavior to help establish control and education programs. The study was conducted at Ege University, Izmir, Turkey, during the 1999-2000 academic year. A total of 2,217 first- and fourth-year students determined by stratified sampling constituted the study group. All students who volunteered to participate completed a questionnaire assessing sociodemographic and knowledge factors, sexual attitudes, behavior, and history of STDs. The rate of students having had sexual experience was 36.6%. Males were more sexually active than females. Most students (71.4%) began sexual activity at ages 15-19 without any difference by gender. Males reported significantly more sexual partners than females. Similarly, the rate of male students never using condoms was significantly higher than females. Condom was the most frequent contraception method, followed by oral contraceptives and withdrawal. Mean score on the knowledge questions was 16.29 (highest score 30). The most widely known STD was HIV infection and AIDS. Students' knowledge of transmission routes, signs and symptoms, and risk groups of STDs was insufficient. Main sources of knowledge were visual and print media, and friends. Most students (84.7%) viewed prevention from STDs as a person's own responsibility. Young people in Turkey are sexually active and tend to engage in high-risk behavior. However, their knowledge on sexual health and sexually transmitted diseases is insufficient. Study results suggest a need for implementation of STD control programs and provision of school sexuality education for adolescents and young adults.

    Introduction More knowledge is needed about structural factors in society that affect risky sexual behaviors. Educational institutions such as universities provide an opportune arena for interventions among young people. The aim of this study was to investigate the relationship between sociodemographic and religious factors and their impact on sexual behavior among university students in Uganda. Methods In 2005, 980 university students (response rate 80%) were assessed by a self-administered questionnaire. Validated instruments were used to assess socio-demographic and religious factors and sexual behavior. Logistic regression analyses were applied. Results Our findings indicated that 37% of the male and 49% of the female students had not previously had sex. Of those with sexual experience, 46% of the males and 23% of the females had had three or more sexual partners, and 32% of the males and 38% of the females did not consistently use condoms. For those who rated religion as less important in their family, the probability of early sexual activity and having had a high number of lifetime partners increased by a statistically significant amount (OR = 1.7; 95% CI: 1.2–2.4 and OR = 1.6; 95% CI: 1.1–2.3, respectively). However, the role of religion seemed to have no impact on condom use. Being of Protestant faith interacted with gender: among those who had debuted sexually, Protestant female students were more likely to have had three or more lifetime partners; the opposite was true for Protestant male students. Conclusion Religion emerged as an important determinant of sexual behavior among Ugandan university students. Our findings correlate with the increasing number of conservative religious injunctions against premarital sex directed at young people in many countries with a high burden. of HIV/AIDS. Such influence of religion must be taken into account in order to gain a deeper understanding of the forces that shape sexual behavior in Uganda. PMID

    The relationship between participation in a sex education course in the public schools and premarital sexual behavior is studied using cross-sectional data from a national probability sample of 1177 male and female American college students interviewed in detail about their sexual behavior and sexual socialization experiences. There was no significant difference between the premarital heterosexual involvement of individuals who had attended a sex education course and those who had not. Furthermore, there were no differences between those who received information on birth control or coitus and those who did not. The implications of these findings for sex education programs are discussed and speculations about successful and unsuccessful programs are made.

    Sexual arousal is thought to be the result of the processing of sexual cues at two levels: conscious and unconscious. Whereas numerous studies have examined the affective and motivational responses to supraliminal (consciously processed) sexual cues, much less is known regarding the responses to subliminal (processed outside of one's awareness) sexual cues. Five studies examined responses to subliminal sexual cues. Studies 1–3 demonstrated increases in adults' positive affect following exposure to subliminal sexual cues compared to control cues. Study 4 demonstrated that the positive affect resulting from exposure to subliminal sexual cues increased motivation to further engage in a neutral task. Study 5 provided evidence suggesting that the affect and motivation found in Studies 1–4 were associated with motivation to engage in sex specifically, rather than a general approach motivation. The implications of these findings for the processing of subliminal sexual cues and for human sexuality are discussed. PMID:26494359

    The discipline of behavioral economics integrates principles from psychology and economics to systematically characterize decision-making preferences. Two forms of behavioral economic decision making are of relevance to HIV risk behavior: delay discounting, reflecting preferences for immediate small rewards relative to larger delayed rewards (i.e., immediate gratification), and probability discounting, reflecting preferences for larger probabilistic rewards relative to smaller guaranteed rewards (i.e., risk sensitivity). This study examined questionnaire-based indices of both types of discounting in relation to sexual risk taking in an emergency department sample of hazardous drinkers who engage in risky sexual behavior. More impulsive delay discounting was significantly associated with increased sexual risk-taking during a drinking episode, but not general sexual risk-taking. Probability discounting was not associated with either form of sexual risk-taking. These findings implicate impulsive delay discounting with sexual risk taking during alcohol intoxication and provide further support for applying this approach to HIV risk behavior.

    Latino gay men are at high risk for HIV/AIDS, and therefore it is critical that we increase our understanding of their sexual behavior. This paper discusses theoretical and methodological issues of conducting research with Latino gay and bisexual men. The importance of culture in psychological theory addressing sexual behavior is highlighted. Cultural and socioeconomic forces that impact the social construction of sexuality and sexual risk need to be taken into account to increase research validity. Social context and internalized sociocultural experiences can affect a variety of issues, including sexual scripts and the definition and fluidity of sexual orientation identity. Moreover, Latino gay men's sexuality may be influenced by experiences of oppression, discrimination, racism, and homophobia. Level of acculturation should also be considered. Measures that are developed by taking into account the cultural context and incorporating a Latino perspective are helpful in conducting meaningful research. Triangulation of quantitative and qualitative methods will help provide a picture rich in context and at the same time generalizable. The relationship between researchers and participants is affected by Latino cultural styles, and suggestions for approaches to conduct research in the Latino gay community are offered.

    It is known that in goldfish Carassius auratus, a non-sex changing fish, prostaglandin (PG) treatment can induce female-typical sex behavior in males, and androgen treatment can induce male-typical sex behavior in females. These facts suggest that goldfish have a sexually bipotential brain even after attaining sexual maturity unlike mammals which have sexually differentiated brain. In the present study, in order to further characterize the brain function of goldfish, whether hormonal treatments which induce heterotypical sexual behavior suppress the occurrence of sex-typical behavior and whether sex-typical and heterotypical behavior can be induced in a relatively short time were examined. In the first series of experiments, male goldfish were shown to retain their ability to perform male-typical sex behavior within a week after being induced to perform female-typical behavior. Likewise, female goldfish were also shown to retain their female-typical sex behavior a week after being induced to perform male-typical behavior. In the second series of experiments, when PG-injected experimental males were placed with both PG-injected females and sexually mature males, the experimental males performed male- and female-typical behavior alternately with the females and the males, respectively during 90 min test period. When methyltestosterone-treated experimental females were injected with PG and placed with both PG-injected females and mature males, the experimental females performed male- and female-typical behavior alternately during 90 min test period. The results of the present study are consistent with the current knowledge that goldfish possess a sexually bipotential brain that can regulate both male and female-typical sex behaviors.

    Two models of risky sexual behavior (RSB) were compared in a community sample of late adolescents (N = 223). For the traumagenic model, early negative sexual experiences were posited to lead to an association between negative affect with sexual relationships. For the cognitive escape model, depressive affect was posited to lead to engagement in RSB as a way to avoid negative emotions. The current study examined whether depression explained the relationship between sexual trauma and RSB, supporting the cognitive escape model, or whether it was sexual trauma that led specifically to RSB, supporting the traumagenic model. Physical trauma experiences were also examined to disentangle the effects of sexual trauma compared to other emotionally distressing events. The study examined whether the results would be moderated by participant sex. For males, support was found for the cognitive escape model but not the traumagenic model. Among males, physical trauma and depression predicted engagement in RSB but sexual trauma did not. For females, support was found for the traumagenic and cognitive escape model. Among females, depression and sexual trauma both uniquely predicted RSB. There was an additional suppressor effect of socioeconomic status in predicting RSB among females. Results suggest that the association of trauma type with RSB depends on participant sex. Implications of the current study for RSB prevention efforts are discussed.

    Mental health and school adjustment problems are thought to distinguish early sexual behavior from normative timing (16-18 years), but little is known about how early sexual behavior originates from these problems in middle-childhood. Existing studies do not allow for co-occurring problems, differences in onset and persistence, and there is no information on middle-childhood school adjustment in relationship to early sexual activity. This study examined associations between several middle-childhood problems and early sexual behavior, using a subsample (N = 4,739, 53 % female, 98 % white, mean age 15 years 6 months) from a birth cohort study, the Avon Longitudinal Study of Parents and Children. Adolescents provided information at age 15 on early sexual behavior (oral sex and/or intercourse) and sexual risk-taking, and at age 13 on prior risk involvement (sexual behavior, antisocial behavior and substance use). Information on hyperactivity/inattention, conduct problems, depressive symptoms, peer relationship problems, school dislike and school performance was collected in middle-childhood at Time 1 (6-8 years) and Time 2 (10-11 years). In agreement with previous research, conduct problems predicted early sexual behavior, although this was found only for persistent early problems. In addition, Time 2 school dislike predicted early sexual behavior, while peer relationship problems were protective. Persistent early school dislike further characterized higher-risk groups (early sexual behavior preceded by age 13 risk, or accompanied by higher sexual risk-taking). The study establishes middle-childhood school dislike as a novel risk factor for early sexual behavior and higher-risk groups, and the importance of persistent conduct problems. Implications for the identification of children at risk and targeted intervention are discussed, as well as suggestions for further research.

    To obtain information regarding sexual behavior and related policies in state residential facilities for individuals with mental retardation/developmental disabilities, we sent surveys to 168 members listed in the Association of Public Developmental Disabilities Administrators 1998-1999 directory. Response rate was 68.5%. For the 46 facilities where 50% or fewer of clients had profound retardation, sexual relations between clients was reported to occur "sometimes" or "often" by 29 (63%). Six of 115 (5.2%) administrators reported at least one client with a sexually transmitted disease (STD) in the past year. Of 110 instances of sexual abuse reported, the perpetrator was another client in 63% of cases. Ninety-six percent of administrators (n = 110) reported their facility had written guidelines concerning sexual abuse. Careful monitoring of STDs and the effectiveness of sex education will be instrumental in preventing HIV/STDs and helping prevent sexual abuse in this vulnerable population.

    Sexual behavior over the past year of 32 outpatients with Bipolar disorder is compared to that of 44 Comparison patients that had never had an episode of affective illness. Subjects were outpatients treated with drugs and psychotherapy in routine office practice. Differences in sexual behavior between the two groups as a whole were minimal, but meaningful differences emerged when subgroups were compared. Compared to control men, Bipolar men had had more partners in the last year and were more likely to have had sex without condoms. Compared to Bipolar females, Bipolar males had more sex partners, had more sex with strangers, and were more likely to have engaged in homosexual behavior. Even so, some patients in the Comparison group also had engaged in risky sexual behavior. They had failed to use condoms and had had sex with strangers and prostitutes during the previous year.

    Perinatal administration of the endocrine disruptor bisphenol A (BPA) reportedly inhibits the sexual behavior of sexually naïve adult male rats. In order to evaluate the effects of BPA administration during early development on later reproductive behavior, we administered one of five doses of bisphenol A daily to pregnant female rats throughout gestation and lactation, and quantified the appetitive and consummatory sexual behaviors of the resultant male and female offspring over multiple sexual encounters in adulthood. Males receiving low dose perinatal BPA (50 μg/kg bw/day) showed persistent deficits in sexual behavior in adulthood. Males receiving the highest dose (5 mg/kg bw/day), however, were indistinguishable from controls with respect to consummatory sexual behaviors but showed decreased latencies to engage in those behaviors when sexually naïve, with significant non-linear, or U-shaped, dose-response relationships observed on the first and last day of testing. Adult female sexual behavior was not affected by early BPA administration at any dose tested. These results are consistent with previous reports that BPA exerts behavioral effects especially at low doses, and further indicates that BPA can cause lasting impairment of sexual behavior in males, but does not alter the normal development of female appetitive or consummatory sexual behaviors. To our knowledge, this is the first report indicating that adult sexual performance is impaired in sexually experienced animals following perinatal exposure to bisphenol A.

    Nearly 20 million new sexually transmitted infections occur every year in the United States. Traditionally, men have demonstrated much greater risk for contraction of and mortality from STDs perhaps because they tend to engage in a number of risky sexual activities. Research on masculinity suggests that gender roles influence males' sexual health by encouraging risk-taking behavior, discouraging access to health services, and narrowly defining their roles as partners. However, despite the propensity of highly masculine men to engage in high-risk sexual behavior, there is reason to suspect that men at the other end of the continuum may still be driven to engage in similar high-risk behaviors as a consequence of gender socialization. Discrepancy stress is a form of gender role stress that occurs when men fail to live up to the ideal manhood derived from societal prescriptions (i.e., Gender Role Discrepancy). In the present study, we surveyed a national sample of 600 men via Amazon Mechanical Turk to assess perceived gender role discrepancy, experience of discrepancy stress, and the associations with risky sexual behavior and potential contraction of STDs. Results indicated that men who believe they are less masculine than the typical man (i.e., gender role discrepancy) and experience distress stemming from this discrepancy (i.e., discrepancy stress) engage in high-risk sexual behavior and are subsequently diagnosed with more STDs. Findings are discussed in relation to implications for primary prevention strategies.

    Purpose American Indian (AI) adolescent girls have higher rates of sexual activity, births and STIs compared to the national average. The purpose of this study was to explore factors that influence urban adolescent AI girls' sexual risk behavior (SRB). Design A qualitative study was conducted using grounded theory methodology to reveal factors and processes that influence SRB. Methods Talking circles, individual interviews, and event history calendars were used with 20 urban AI 15-19 year old girls to explore influences on their sexual behavior. Findings The generated theory, Framing Sexual Risk Behavior, describes both social and structural factors and processes that influenced the girls' sexual behaviors. The theory extends Bronfenbrenner's ecological model by identifying microsystem, mesosystem, and macrosystem influences on sexual behavior, including: Microsystem: Being “Normal,” Native, and Having Goals; Mesosystem: Networks of Family and Friends, Environmental Influences, and Sex Education; and Macrosystem: Tribal Traditions/History and Federal Policy. Discussion Urban AI girls reported similar social and structural influences on SRB as urban adolescents from other racial and ethnic groups. However, differences were noted in the family structure, cultural heritage, and unique history of AIs. Implications for Practice This theory can be used in culturally responsive practice with urban AI girls. PMID:24803532

    Online partner seeking is associated with sexual risk behavior among young adults (specifically men who have sex with men), but this association has yet to be explored among a probability sample of adolescents. Moreover, cell phone internet access and sexual risk taking online and offline have not been explored. A probability sample (N = 1,831) of Los Angeles Unified School District high school students was collected in 2011. Logistic regression models assessed relationships between specific sexual risk behaviors (online sexual solicitation, seeking partners online, sex with internet-met partners, condom use) and frequency of internet use, internet access points, and demographics. Students with cell phone internet access were more likely to report being solicited online for sex, being sexually active, and having sex with an internet-met partner. Bisexual-identifying students reported higher rates of being approached online for sex, being sexually active, and not using condoms at last sex. Gay, lesbian, and questioning (GLQ) students were more likely to report online partner seeking and unprotected sex at last sex with an internet-met partner. Additionally, having sex with an internet-met partner was associated with being male, online sexual solicitation, and online partner seeking. Internet- and school-based sexual health programs should incorporate safety messages regarding online sexual solicitation, seeking sex partners online, and engaging in safer sex practices with all partners. Programs must target adolescents of all sexual identities, as adolescents may not yet be “out,” and bisexual and GLQ adolescents are more likely to engage in risky sex behaviors. PMID:25344027

    Online partner seeking is associated with sexual risk behavior among young adults (specifically men who have sex with men), but this association has yet to be explored among a probability sample of adolescents. Moreover, cell phone internet access and sexual risk taking online and offline have not been explored. A probability sample (N = 1,831) of Los Angeles Unified School District high school students was collected in 2011. Logistic regression models assessed relationships between specific sexual risk behaviors (online sexual solicitation, seeking partners online, sex with internet-met partners, condom use) and frequency of internet use, internet access points, and demographics. Students with cell phone internet access were more likely to report being solicited online for sex, being sexually active, and having sex with an internet-met partner. Bisexual-identifying students reported higher rates of being approached online for sex, being sexually active, and not using condoms at last sex. Gay, lesbian, and questioning (GLQ) students were more likely to report online partner seeking and unprotected sex at last sex with an internet-met partner. Additionally, having sex with an internet-met partner was associated with being male, online sexual solicitation, and online partner seeking. Internet- and school-based sexual health programs should incorporate safety messages regarding online sexual solicitation, seeking sex partners online, and engaging in safer sex practices with all partners.

    Over the past two decades the sexual content on television has increased in frequency and explicitness but has seldom included depiction of the use of contraceptives. Concurrently, the age of initiation of heterosexual intercourse has decreased and the number of teenaged pregnancies has remained high. Are these trends related? This survey of 391 adolescents found that those who chose heavier diets of sexy television shows were more likely than those who viewed a smaller proportion of sexual content on television to have had sexual intercourse. This relationship held regardless of perceived peer encouragement to engage in sex and across race and gender groups. While causal direction is not clear from these data, the relationship suggests that either sexual activity results in increased interest in sexual content in the media and/or that viewing such content leads to sexual activity. In either case, the finding points to the need for further research and increased discussion and portrayal of the use of contraceptives on television.

    There appears to be a good deal of disagreement between professionals as to what constitutes child abuse. Attorneys as a group have been found to judge behaviors associated with child abuse more leniently than other abuse professionals. However, no one has discriminated between defense and prosecuting attorneys in these areas. It was hypothesized that because of divergent roles in child sexual abuse cases attitudes toward adult-child behaviors associated with sexual abuse would differ among attorney groups. Two prosecuting and two defense attorneys from every county in the state of Indiana were sent questionnaires. Participants were asked to indicate if a behavior was acceptable, inappropriate, or sexual abuse if it occurred on one or on multiple occasions. Prosecutors had more severe judgements than the defense attorneys on 32 of the 42 behaviors. They were more likely to indicate that a behavior was inappropriate or abuse. Cognitive dissonance theory is proposed as a possible explanation for these findings.

    Behavioral interventions to reduce sexual risk behavior depend on strong health behavior theory. By identifying the psychosocial variables that lead causally to sexual risk, theories provide interventionists with a guide for how to change behavior. However, empirical research is critical to determining whether a particular theory adequately explains sexual risk behavior. A large body of cross-sectional evidence, which has been reviewed elsewhere, supports the notion that certain theory-based constructs (e.g., self-efficacy) are correlates of sexual behavior. However, given the limitations of inferring causality from correlational research, it is essential that we review the evidence from more methodologically rigorous studies (i.e., longitudinal and experimental designs). This systematic review identified 44 longitudinal studies in which investigators attempted to predict sexual risk from psychosocial variables over time. We also found 134 experimental studies (i.e., randomized controlled trials of HIV interventions), but of these only 9 (6.7 %) report the results of mediation analyses that might provide evidence for the validity of health behavior theories in predicting sexual behavior. Results show little convergent support across both types of studies for most traditional, theoretical predictors of sexual behavior. This suggests that the field must expand the body of empirical work that utilizes the most rigorous study designs to test our theoretical assumptions. The inconsistent results of existing research would indicate that current theoretical models of sexual risk behavior are inadequate, and may require expansion or adaptation.

    2003-04-01

    This is the first of two papers which briefly outline the development of behavioral and cognitive behavioral treatment of sexual offenders from the mid-1800s to 1969. We first consider the historic role of Sigmund Freud and note that a broad scientific interest in deviant sexual behaviour was well established by 1900. In the early to mid-20th century, two psychologies were prominent in the development of behaviorial approaches, those of John B. Watson and Alfred Kinsey. Behavior therapy for a variety of problems emerged in the 1950s and soon found application to deviant sexuality. The development of penile plethysmography helped to focus interest on deviant sexual preference and behavior. While nonbehavioral approaches to sexual offenders paralleled these developments, a combination of behavioral and cognitive behavioral treatments began to emerge in the late 1960s which ultimately developed into the approaches more commonly seen today.

    Sexual behavior and formation of sexuality in men with obsessive-compulsive disorder is one of the pressing issues in contemporary medicine. Obsessive-compulsive disorder is characterized by the development of intrusive thoughts, memories, movements and actions, as well as a variety of pathological fears (phobias). Increase in the number of patients with this pathology in modern clinical practice of neurotic disorders, the young age of the patients and as a result violation of interpersonal, communicational and sexual nature is quite apparent. The study involved 35 men aged 23 to 47 years with clinical signs of OCD. We determined the severity of obsessive-compulsive symptoms using the Yale-Brown scale. We established the presence of a mild degree of disorder in 34,3% of cases; in 48,6% of cases disorder of moderate severity was diagnosed; remaining 17.1% were assessed subclinical condition of OCD at the applicable scale. The system of motivational maintenance of sexual behavior in men with obsessive-compulsive disorders is investigated. Motives of sexual behavior of the investigated men with the pathology are determined. The presented research in men with OCD have established multidimensionality and complexity of motivational ensuring of sexual behavior.

    Rates of STIs, HIV, and pregnancy remain high among adolescents in the US, and recent approaches to reducing sexual risk have shown limited success. Future expectations, or the extent to which one expects an event to actually occur, may influence sexual risk behavior. This prospective study uses longitudinal data from the National Longitudinal Survey of Youth 1997 (n = 3,205 adolescents; 49.8% female) to examine the impact of previously derived latent classes of future expectations on sexual risk behavior. Cox regression and latent growth models were used to determine the effect of future expectations on age at first biological child, number of sexual partners, and inconsistent contraception use. The results indicate that classes of future expectations were uniquely associated with each outcome. The latent class reporting expectations of drinking and being arrested was consistently associated with the greatest risks of engaging in sexual risk behavior compared with the referent class, which reported expectations of attending school and little engagement in delinquent behaviors. The class reporting expectations of attending school and drinking was associated with having greater numbers of sexual partners and inconsistent contraception use but not with age at first biological child. The third class, defined by expectations of victimization, was not associated with any outcome in adjusted models, despite being associated with being younger at the birth of their first child in the unadjusted analysis. Gender moderated specific associations between latent classes and sexual risk outcomes. Future expectations, conceptualized as a multidimensional construct, may have a unique ability to explain sexual risk behaviors over time. Future strategies should target multiple expectations and use multiple levels of influence to improve individual future expectations prior to high school and throughout the adolescent period.

    The present meta-analysis studies the relations of pubertal timing and status with sexual behavior and sexual risk behavior among youth aged 10.5-22.4 years. We included biological sex, age, and ethnicity as potential moderators. Four databases were searched for studies (published between 1980 and 2012) on the relation between pubertal timing or status and sexual behavior. The outcomes were (1) sexual intercourse; (2) combined sexual behavior; and (3) risky sexual behavior. Earlier pubertal timing or more advanced pubertal status was related to earlier and more sexual behavior, and earlier pubertal timing was related to more risky sexual behavior. Further, the links between (1) pubertal status and combined sexual behavior and (2) pubertal timing and sexual intercourse status, combined sexual behavior, and risky sexual behavior were stronger for girls than boys. Most links between pubertal status, timing, and sexual behavior and sexual risk behavior were stronger for younger adolescents. Moderation by ethnicity did not yield consistent results. There was significant variation in results among studies that was not fully explained by differences in biological sex, age, and ethnicity. Future research is needed to identify moderators that explain the variation in effects and to design sexual health interventions for young adolescents.

    High- versus low-novelty exploration predicts a variety of behavioral differences. For example, rats selectively bred for high-novelty exploration (bred-high responders, bHR) exhibit exaggerated aggression, impulsivity, and proclivity to addictive behaviors compared with low-novelty reactive rats (bred-low responders, bLRs), which are characterized by a high anxiety/depressive-like phenotype. Since bHR/bLR rats exhibit differences in dopaminergic circuitry and differential response to rewarding stimuli (i.e., psychostimulants, food), the present study examined whether they also differ in another key hedonic behavior-sex. Thus, adult bHR/bLR males were given five 30-min opportunities to engage in sexual activity with a receptive female. Sexual behavior and motivation were examined and compared between the groups. The bHR/bLR phenotype affected both sexual motivation and behavior, with bLR males demonstrating reduced motivation for sex compared with bHR males (i.e., fewer animals copulated, longer latency to engage in sex). The bHR males required more intromissions at a faster pace per ejaculation than did bLR males. Thus, neurobiological differences that affect motivation for drugs of abuse, aggression, and impulsivity in rats also affect sexual motivation and performance. PMID:23398441

    A multi-dimensional measure assessing distinct motivations for and against sex was shown to be reliable, valid, and configurally invariant among incoming first-year college students. Three Motivations Against Sex Questionnaire (MASQ) subscales were developed to measure motivations against sexual behavior (Values, Health, Not Ready) to complement and extend a set of Sexual Motivations Scale – Revised (SMS-R; Cooper, Shapiro, & Powers, 1998) subscales assessing motivations for sexual behavior (Intimacy, Enhancement, Coping). Participants were surveyed the summer prior to college (N = 1653; 58.4% female). Exploratory factor analysis on a random one-quarter of respondents supported the hypothesized factors. Multi-group confirmatory factor analysis demonstrated good overall fit to the data and configural invariance across gender and ethnicity and across lifetime sexual experience. Motivations were associated with lifetime oral and penetrative sexual behaviors. This combined measure may be used for identifying motivations, predicting behaviors, and tailoring motivational interventions for sexual health among adolescents and young adults. PMID:20581394

    This study examined parental, peer, and media influences on Taiwanese adolescents' attitudes toward premarital sex and intent to engage in sexual behavior. Participants included a convenience sample of 186 adolescents aged 13-15 recruited from two middle schools in Taiwan. Parental influence was indicated by perceived parental disapproval toward premarital sex and perceived peer sexual behavior was used to measure peer influence. Media influence was measured by the adolescents' perception of whether the media promotes premarital sex. We conducted structural equation modeling to test a hypothesized model. The findings suggested that the perceived sexual behavior of peers had the strongest effect on Taiwanese adolescents' sexual attitudes and behavioral intent, while parental disapproval and media influence also significantly contributed to adolescents' sexual attitudes and intent to engage in sex. School nurses are in an ideal position to coordinate essential resources and implement evidence-based sexually transmitted infection and HIV/AIDS prevention interventions that address issues associated with the influence of parents, peers, and media.

    Sexually transmitted infections (STIs) including human immunodeficiency virus (HIV) have disproportionately affected the non-Hispanic black population in the United States. A person's community can affect his or her STI risk by the community's underlying prevalence of STIs, sexual networks, and social influences on individual behaviors. Racial residential segregation-the separation of racial groups in a residential context across physical environments-is a community factor that has been associated with negative health outcomes. The objective of this study was to examine if non-Hispanic blacks living in highly segregated areas were more likely to have risky sexual behavior. Demographic and sexual risk behavior data from non-Hispanic blacks aged 15-44 years participating in the National Survey of Family Growth were linked to Core-Based Statistical Area segregation data from the U.S. Census Bureau. Five dimensions measured racial residential segregation, each covering a different concept of spatial variation. Multilevel logistic regressions were performed to test the effect of each dimension on sexual risk behavior controlling for demographics and community poverty. Of the 3643 participants, 588 (14.5%) reported risky sexual behavior as defined as two or more partners in the last 12 months and no consistent condom use. Multilevel analysis results show that racial residential segregation was associated with risky sexual behavior with the association being stronger for the centralization [aOR (95% CI)][2.07 (2.05-2.08)] and concentration [2.05 (2.03-2.07)] dimensions. This suggests risky sexual behavior is more strongly associated with neighborhoods with high concentrations of non-Hispanic blacks and an accumulation of non-Hispanic blacks in an urban core.

    In order to study the role of sex steroids in the differentiation of chick behavior, two groups of experiments were carried out. The first part of the study documented sexual dimorphisms in three behavioral measures in chicks: open-field activity, flocking response, and masculine sexual behavior activated by testosterone (crowing, waltzing, and mating attempts). In the second part, possible organizing influences on these sexually dimorphic behaviors were examined. Male and female embryos were injected with estradiol benzoate (EB) or testosterone propionate (TP). Treatment of males with EB or TP demasculinized all three behaviors. None of the steroid treatments had any effect on the behavior of the females. Plasma testosterone levels of the chicks were not affected by any of these treatments, either before or after testosterone activation. Comb weight was reduced by treatment of male embryos with EB and increased by TP in female embryos, which suggests different mechanism for the development of somatic and behavioral characteristics. The results suggest that exogenous T or E given embryonically can exert similar effects on both sexual behavior and nonreproductive activity of chicks. PMID:2066077

    We used the 2011 Arkansas Youth Risk Behavior Survey to estimate the prevalence of risky sexual behavior and sexual assault and to measure its association with teen suicidality. In Arkansas, 50.3% of students reported ever having sexual intercourse, 26% onset at 14 or younger, 36 % having had more than one partner, and 10.2% having been physically forced to have sex. "Being forced to have sex" was a risk factor for depression and all components of the suicide continuum. Additionally, early onset of sexual activity and having more than one partner increased the risk for depression, suicidal ideation, plan, and attempt. Suicide is a grievous and preventable tragedy, sadly standing among the leading causes of death for teens.' In this series, we examine risk factors for suicidality among Arkansas high school students; in this installment, we examine sexual behavior. A previous study utilizing the Rhode Island Youth Risk Behavior Survey (YRBS) found an association between having forced sexual intercourse and suicide. Furthermore, an association between psychiatric disorders and risky sexual behaviors, including both early onset and number of partners was found in a birth cohort study revealed. We hypothesize that Arkansas' teens reporting risky sexual behavior and sexual assault are at higher risk of depression and suicidality as well.

    Existing studies suggest that individual and household level economic shocks affect the demand for and supply of risky sex. However, little evidence exists on the effects of an aggregate shock on equilibrium risky sexual behavior. This paper examines the effects of the early twenty-first century copper boom on risky sexual behavior in Zambian copper mining cities. The results suggest that the copper boom substantially reduced rates of transactional sex and multiple partnerships in copper mining cities. These effects were partly concentrated among young adults and copper boom induced in-migration to mining cities appears to have contributed to these reductions.

We conducted a qualitative study to explore access and influences on sexual health care seeking among bisexual men in Vientiane. In 2013, behaviorally bisexual men were recruited from bars, clubs and dormitories for 5 focus group discussions and 11 in-depth interviews. Participants (aged 18-35 years) commonly reported high-risk sexual behaviors, yet most had never been tested for HIV, and none reported testing for sexually transmitted infections. Common barriers to testing were low perception of risk, expectation of symptoms, fear of HIV, shyness, perceived stigma, confidentiality concerns, and waiting times. Many men were unaware of available services. Most clinics cannot provide comprehensive HIV and sexually transmitted infection services. Strategies are needed to generate demand for testing, improve the capacity of sexual health care providers, and promote available services among behaviorally bisexual men in Vientiane.

    A variety of sexual behaviors occur online, including those that are highly unusual or even plainly illicit. There is a growing body of literature pertaining to sexual abuse of minors that occurs or may be promoted online, but there is a paucity of information regarding other Internet-based sexual interactions, such as manufacturing, dissemination, and online viewing of other atypical sexual material. In this article, I explore and analyze these different practices, which include, but are not limited to, videos of rape, sadomasochism with bodily disfigurement, zoophilia, and necrophilia, with the intention of diminishing the gap in information about this industry. The impact that these behaviors may have on clinical or forensic psychiatric evaluations is discussed, along with pertinent legal regulations and ethics-related considerations. PMID:25492077

    A variety of sexual behaviors occur online, including those that are highly unusual or even plainly illicit. There is a growing body of literature pertaining to sexual abuse of minors that occurs or may be promoted online, but there is a paucity of information regarding other Internet-based sexual interactions, such as manufacturing, dissemination, and online viewing of other atypical sexual material. In this article, I explore and analyze these different practices, which include, but are not limited to, videos of rape, sadomasochism with bodily disfigurement, zoophilia, and necrophilia, with the intention of diminishing the gap in information about this industry. The impact that these behaviors may have on clinical or forensic psychiatric evaluations is discussed, along with pertinent legal regulations and ethics-related considerations.

    A grounded theory approach was used to describe how males and females in late adolescence communicate with their sexual partners about sexual risk behaviors. Interviews were audiotaped with 18 women and 15 men from a university in the southeastern United States. Verbatim transcripts were analyzed using constant comparative analysis. Building trust was identified as the core variable for both men and women. For women, prerequisites for building trust were being involved in caring relationships and indirectly gathering information about potential sexual partners. For men, prerequisites were being involved in caring relationships and using their instincts. Women usually initiated safe-sex talk, but men were willing to discuss it, once the conversation was initiated. Findings can serve as a guide for developing nursing strategies that promote more effective communication about sexual risk behavior in this age group. PMID:9615598

    Pheromone and odor signals play a pivotal role in male mouse reproductive behaviors, such as sexual and aggressive behavior. There are several methods used to assess male behaviors, each of which examines a unique aspect of the biological function of mice. There are two major ways of assessing male aggressive behavior in mice, one is using isolation-induced aggression, and the other is territorial aggression in pair-housed males. To analyze male sexual behavior, a female mouse that is hormone-primed with estradiol and progesterone is usually introduced into a male home range, and mounting, intromission, and ejaculation behaviors are observed for 1 h. Here, we summarize the detailed protocols for assessing male behaviors.

    OBJECTIVE To analyze the relationships between sexual behavior and risk factors to physical and mental health in adolescents. METHODS Study of 3,195 pupils aged 15 to 19 in secondary education, in public and private schools in 10 state capitals in Brazil between 2007 and 2008. Multi-stage (schools and pupils) cluster sampling was used in each city and public and private educational network. All of the students selected completed a questionnaire on the following items: socioeconomic and demographic data; sexual behavior; having sex with those of the same sex, the opposite sex, or both; alcohol and cannabis use; using condoms; traumatic sexual experiences as a child or adolescent; suicidal thoughts. The analysis included describing frequencies, Chi-square test, analysis of multiple and cluster correspondence. Responses to an open ended question in which the adolescent expressed general comments about themselves and their lives were qualitatively analyzed using content analysis. RESULTS Around 3.0% of adolescents reported homosexual or bisexual behavior, with no difference according to sex, age, skin color, social status family structure or educational network. Adolescents with homosexual/bisexual sexual behavior, compared to their heterosexual peers, reported: (p < 0.05): getting drunk (18.7% and 10.5%, respectively), frequent cannabis use (6.1% and 2.1%, respectively), suicidal thoughts (42.5% and 18.7%, respectively), and having been the victim of sexual violence (11.7% and 1.5%; respectively). Adolescents with homosexual/bisexual sexual behavior reported that they used condoms less frequently (74.2%) than their heterosexual peers (48.6%, p < 0.001). In the correspondence analysis, three groups were found, one composed of adolescents with homosexual/bisexual behavior and experiencing risk factors; suffering sexual violence, never using a condom, suicidal thoughts, frequent cannabis use; another composed of occasional cannabis and condom users, who got drunk

    Fluidity in attractions and behaviors among same-sex attracted women has been well-documented, suggesting the appropriateness of dynamical systems modeling of these phenomena over time. As dynamical systems modeling offer an approach to explaining the patterns of complex phenomena, it may be apt for explaining variability in female same-sex sexuality. The present research is the first application of this analytical approach to such data. Dynamical systems modeling, and specifically generalized local linear approximation modeling, was used to fit daily diary data on same-sex attractions and behaviors over a 21 day period among a group of 33 sexual minority women characterized as lesbian, bisexual or "fluid" based on their identity histories. Daily measures of women's reported same-sex attractions were fit using a linear oscillator model and its parameters estimated the cyclicity in these attractions. Results supported the existence of a "core sexual orientation" for women in this sample, regardless of how they identified and despite a high degree of variability in daily same-sex attractions. Thus, modeling individual differences in the variability of attractions and behaviors of sexual minority women may be critical to furthering our understanding of female same-sex sexuality and human sexual orientation more broadly.

    This article summarizes data from a qualitative study investigating the ways in which female youth perceive and respond to challenges related to the interplay of late adolescence and a minority sexual orientation. Fifteen sexual minority females in late adolescence were interviewed individually and in focus groups. The interviews focused on participants' perceptions of challenges, the impact those stressors have in their lives, and methods they utilize to cope with them. The most common negative experiences reported were isolation, lack of acceptance, harassment, and violence. Sub-themes include: hearing negative messages about gender and sexual orientation, pressures to conform to a variety of cultural norms including gender norms, fears of future violence, and pressure to identify sexual orientation. Collectively, the participants described these negative consequences of experiences of heterosexism, sexism, and racism as their most difficult experiences. The most common responses to these stressors reported by participants were finding support in relationships, engaging in coping responses, pursuing education and activism, rebellion and resistance, and avoidance and deferment.

  16. Evolution of sexuality: biology and behavior

    PubMed Central

    2005-01-01

    Sexual reproduction in animals and plants is far more prevalent than asexual reproduction, and there is no dearth of hypotheses attempting to explain why. Even bacteria and viruses, which reproduce by cloning, engage in promiscuous horizontal gene exchange (“parasexual reproduction”) on such short time scales that they evolve genotypic diversity even more rapidly than eukaryotes. (We confront this daily in the form of antimicrobial resistance.) The host-parasite and host-pathogen arms race purports to explain the prevalence of sexual reproduction, yet there are over a dozen other hypotheses, including the proposition that sexual reproduction purges the genome of deleterious mutations. An equally daunting challenge is to understand, in terms of evolutionary logic, the jungle of diverse courtship and mating strategies that we find in nature. The phenotypic plasticity of sex determination in animals suggests that the central nervous system and reproductive tract may not reach the same endpoint on the continuum between our stereotypic male and female extremes. Why are there only two kinds of gametes in most eukaryotes? Why are most flowering plants, and few animals, hermaphroditic? Why do male animals compete more for access to females than the other way around in most animals that have been studied?This review presents more questions than answers, but an extraordinary wealth of data has been collected, and new genetic techniques will provide new answers. The possible relevance of these data to human sexuality will be discussed in a future article. PMID:16200180

    The current study investigated sexual initiations within the framework of the Theory of Planned Behavior (TPB) (Ajzen, 1991; Ajzen & Madden, 1986). Male and female daters in heterosexual dating relationships completed an online survey that assessed their sexual relationship with their partner and the TPB components (perceptions of social norms, attitudes, perceived behavioral control, and intentions). The TPB was supported for both men and women in that, as predicted, the more an individual perceived that important others would approve of them initiating sexual activities with their partner, the more positive their evaluations were of the outcomes of initiating, and the more confident they were in their ability to initiate, the stronger were their initiation intentions. In turn, stronger sexual initiation intentions were associated with more frequent initiation behaviors. Compared to women, men initiated more frequently, had stronger sexual initiation intentions, and perceived more positive social norms regarding initiation; men and women did not differ in their attitudes toward sexual initiation or in their perceived behavioral control. Both men and women who reported initiating more frequently and perceived their partner as initiating more frequently reported greater sexual satisfaction. These results are discussed in terms of the utility of the TPB for understanding sexual initiations and the role of the traditional sexual script in initiation-related cognitions and behavior.

  18. The development of female sexual behavior requires prepubertal estradiol.

    The classic view of brain and behavioral sexual differentiation holds that the neural mechanisms controlling sexual behavior in female rodents develop in the absence of ovarian sex hormone actions. However, in a previous study, female aromatase knock-out (ArKO) mice, which cannot convert testosterone to estradiol, showed deficient male-oriented partner preference and lordosis behaviors in response to adult ovarian hormones, raising the possibility that estradiol may contribute to the development of these female sexual behaviors. In the present experiments, administering estradiol prepubertally [between postnatal day 15 (P15) and P25] significantly enhanced the ability of ArKO female mice to display lordosis behavior in response to ovarian hormones administered later in adulthood, whereas treatment with estradiol over an earlier postnatal period (P5-P15) had no such effect. Treatment of ArKO females with estradiol between P15 and P25 also rescued their later preference to approach distal cues from an intact male over an estrous female. ArKO females also displayed significantly less female-directed (male-typical) mounting behavior than wild-type control females when treated with testosterone in adulthood. Prepubertal estradiol treatment failed to reverse this deficit in ArKO females, whereas earlier postnatal estradiol augmented later mounting in both genotypes. Our results provide new evidence for an organizing role of prepubertal estradiol in the development of neural mechanisms that control female-typical sexual behavior.

    In this study, we used data from Add Health Waves II and III to compare men who had been incarcerated to those who had not, and examined whether incarceration was associated with increased numbers of sexual partners and increased odds of concurrent partnerships. We used multivariate regression and propensity-score matching to compare sexual behavior of Wave III male respondents who had been incarcerated with those who had not, and compared sexual behavior at Wave II to identify differences in sexual behavior prior to incarceration. Incarceration was associated with an increased rate of lifetime sexual partnership, but this was attenuated by substance use. Criminal justice involvement was associated with increased odds of having partners who report concurrent partnerships, but no further increase was seen with incarceration. There were no significant sexual behavior differences prior to incarceration. These results suggest that the criminal justice system and substance use may interact to shape sexual behavior.

    OBJECTIVE Despite recent media attention and potential public health importance, little is known about the prevalence and nature of sexting. Using a large school-based sample of adolescents, we examined the prevalence of sexting behaviors, as well as its relation to dating, sex, and risky sexual behaviors. DESIGN Data are from Time 2 of a three-year longitudinal study. Participants self-reported their history of dating, sexual behaviors, and sexting (sent, asked, been asked, bothered by being asked). SETTING Seven public high schools in southeast Texas. PARTICIPANTS A total of 948 public high school students (55.9% female) participated. The sample consisted of African American (26.6%), Caucasian (30.3%), Hispanic (31.7%), Asian (3.4%), and mixed/other (8.0%) teens. MAIN OUTCOME MEASURES Having ever engaged in sexting behaviors. RESULTS 28% of the sample reported having sent a naked picture of themselves through text or email (sext), and 31% reported having asked someone for a sext. Over half (57%) had been asked to send a sext, with a vast majority bothered by having been asked. Adolescents who engaged in sexting behaviors were more likely to have begun dating and to have had sex than those who did not sext (all p<.001). For girls, sexting was also associated with risky sexual behaviors. CONCLUSIONS The results suggest that teen sexting is prevalent, and potentially indicative of teens’ sexual behaviors. Teen-focused health care providers should consider screening for sexting behaviors, so as to provide age-specific education about the potential consequences of sexting, and as a mechanism for discussing sexual behaviors.

    Background Uganda has reduced its prevalence of HIV/AIDS from 18 to 6.5% within a decade. An important factor behind this might have been the response from faith-based voluntary organizations, which developed social capital for achieving this. Three behaviors have been targeted: Abstinence, Being faithful, and Condom use (the ABC strategy). The aim of this study was to explore the association between social capital and the ABC behaviors, especially with reference to religious factors. Methods In 2005, 980 Ugandan university students responded to a self-administered questionnaire (response rate 80%). It assessed sociodemographic factors, social capital, importance of religion, sexual debut, number of lifetime sexual partners, and condom use. Logistic regression analysis was applied as the main analytical tool. Results Thirty-seven percent of the male and 49% of the female students had not had sexual intercourse. Of those with sexual experience, 46% of the males and 23% of the females had had three or more lifetime sexual partners, and 32% of those males and 38% of the females stated they did not always use condoms with a new partner. Low trust in others was associated with a higher risk for not always using condoms with a new partner among male students (OR 1.7, 95% CI 1.1–2.8), and with a lower risk for sexual debut among female students (OR 0.5, 95% CI 0.3–0.9). Non-dominant bridging trust among male students was associated with a higher risk for having had many sexual partners (OR1.8, 95% CI 1.2–2.9). However, low trust in others was associated with a greater likelihood of sexual debut in men, while the opposite was true in women, and a similar pattern was also seen regarding a high number of lifetime sexual partners in individuals who were raised in families where religion played a major role. Conclusions In general, social capital was associated with less risky sexual behavior in our sample. However, gender and role of religion modified the effect so that

    Study Objective To determine associations between religiosity and female adolescents' sexual and contraceptive behaviors. Design We conducted a secondary analysis on data from a randomized controlled trial comparing interventions designed to prevent pregnancy and STDs. Multivariable modeling assessed the association between a religiosity index consisting of items related to religious behaviors and impact of religious beliefs on decisions and sexual outcomes. Participants 572 female adolescents aged 13 to 21, recruited via a hospital-based adolescent clinic and community-wide advertisements. Main Outcome Measures Sexual experience, pregnancy, STDs, number of lifetime partners, frequency of sexual activity, previous contraceptive use, and planned contraceptive use. Results Mean participant age was 17.4±2.2 years and 68% had been sexually active. Most (74.1%) had a religious affiliation and over half (52.8%) reported that their religious beliefs impact their decision to have sex at least “somewhat.” Multivariate analyses showed that, compared with those with low religiosity, those with high religiosity were less likely to have had sexual intercourse (OR=0.23, 95% CI=0.14, 0.39). Among sexually active participants, those with high religiosity were less likely to have been pregnant (OR=0.46, 95% CI=0.22, 0.97), to have had an STD (OR=0.42, 95% CI=0.22, 0.81), or to have had multiple (≥4) lifetime partners (OR=0.38, 95% CI=0.21, 0.68) compared to those with low religiosity. Levels of religiosity were not significantly associated with frequency of intercourse, contraception use at last intercourse, or planned contraceptive use. Conclusion In this cohort, religiosity appeared to be a protective factor rather than a risk factor with regard to sexual behavior and was not associated with contraception use. PMID:20493738

    In nursing homes, extreme sexual behavior is one of the most challenging behaviors in dementia. Despite this, however, there is no conformity in the literature regarding how to label and define this type of behavior. Examples of labels used include inappropriate sexual behavior, improper sexual behavior, sexually disinhibited behavior, or hyper sexuality. According to recent theoretical perspectives, extreme sexual behavior may be regarded as a part of disinhibited behavior or could be considered as an independent neuropsychiatric symptom. In this multicenter study, it was investigated whether there is a relationship between extreme sexual behavior and the typical neuropsychiatric symptoms seen in dementia. In 179 residents diagnosed with dementia, extreme sexual behavior was measured using an observation scale. Twelve neuropsychiatric symptoms were measured by the Neuropsychiatric Inventory. Multivariate analysis of covariance with gender showed that residents with observed extreme sexual behavior (n = 43) only showed a higher score on neuropsychiatric symptom 'disinhibition', as compared to residents with non-observed sexual behavior (n = 136). In addition, the effect size was large. These findings indicate that among residents with dementia, extreme sexual behaviors should not be considered as an independent neuropsychiatric symptom. Instead, disinhibition may be an important underlying mechanism for extreme sexual behavior and thus validates the label 'sexually disinhibited behavior'.

    Environmental factors play a crucial role in influencing sexual selection in insects and the evolution of their mating systems. Although it has been reported that sexual selection in insects may change in response to varying environments, the reason for these changes remains poorly understood. Here, we focus on the mate selection process of a ladybird, Cryptolaemus montrouzieri, when experiencing low- and high-nutrition diet regimes both in its larval and adult stages. We found that female ladybirds preferred to mate with males reared under high-nutrition diet regimes, regardless of the nutritional conditions they experienced during their own larval stages, indicating that mate choice of female C. montrouzieri is non-random and phenotype-dependent. Such mate choice may depend on visual cues (body or genitalia size) and/or chemical cues (pheromones). Further, females from high-nutrition larval diet regimes produced more eggs than those from low-nutrition larval diet regimes. In addition, diet regimes during adulthood also exerted strong effects on egg production. In summary, our study provides new insight into the mate choice of C. montrouzieri as affected by seasonal changes in resources, and suggests that food availability may be a driving force in mate choice.

    OBJECTIVES: This study examined lifetime prevalence of suicide symptoms and affective disorders among men reporting a history of same-sex sexual partners. METHODS: In the third National Health and Nutrition Examination Survey, men aged 17 to 39 years were assessed for lifetime history of affective disorders and sexual behavior patterns. The study classified this subset of men into 3 groups: those reporting same-sex sexual partners, those reporting only female sexual partners, and those reporting no sexual partners. Groups were compared for histories of suicide symptoms and affective disorders. RESULTS: A total of 2.2% (95% confidence interval [CI] = 1.3%, 3.1%) of men reported same-sex sexual partners. These men evidenced greater lifetime prevalence rates of suicide symptoms than men reporting only female partners. However, homosexually/bisexually experienced men were no more likely than exclusively heterosexual men to meet criteria for lifetime diagnosis of other affective disorders. CONCLUSIONS: These data provide further evidence of an increased risk for suicide symptoms among homosexually experienced men. Results also hint at a small, increased risk of recurrent depression among gay men, with symptom onset occurring, on average, during early adolescence. PMID:10754972

    Understanding what social factors are associated with risk of HIV acquisition and transmission among gay, bisexual and other men who have sex with men (MSM) is a critical public health goal. Experiencing discrimination may increase risk of HIV infection among MSM. This analysis assessed relations between experiences of sexual orientation- and race-based discrimination and sexual HIV risk behavior among MSM in New York City. 1,369 MSM completed a self-administered computerized assessment of past 3-month sexual behavior, experience of social discrimination and other covariates. Regression models assessed relations between recent experience of discrimination and sexual HIV risk behavior. Mean age was 32 years; 32 % were white; 32 % Latino/Hispanic; 25 % African American/Black. Of MSM who self-reported HIV-positive or unknown status (377), 7 % (N = 27) reported having unprotected insertive anal intercourse with an HIV-negative or unknown status partner (“HIV transmission risk”). Of MSM who self-reported HIV-negative status (992), 11 % (110) reported unprotected receptive anal intercourse with an HIV-positive or unknown status partner (“HIV acquisition risk”). HIV acquisition risk was positively associated with sexual orientation-based discrimination in home or social neighborhoods, but not race-based discrimination. We observed that sexual orientation-based discrimination was associated with sexual HIV risk behavior among urban-dwelling MSM. Addressing environmental sources of this form of discrimination, as well as the psychological distress that may result, should be prioritized in HIV prevention efforts. PMID:25381561

    Previous studies suggest that mothers can help adolescents make responsible sexual decisions by talking with them about sexual health. Yet, it is not clear how and when mothers make decisions about talking with their adolescents about sex. We sought to determine: (1) the accuracy of mothers' and adolescents' predictions of adolescents' age of sexual debut; and (2) if mothers' beliefs about their adolescents' sexual behavior affected the frequency of mother-adolescent communication about sexual topics and, in turn, if mother-adolescent communication about sexual topics affected mothers' accuracy in predicting adolescents' current and future sexual behavior. Participants were 129 urban, ethnic minority HIV-negative youth (52% male and 48% female; ages 10-14 years at baseline; ages 13-19 years at follow-up) and their mothers; 47% of mothers were HIV-positive. Most mothers and adolescents predicted poorly when adolescents would sexually debut. At baseline, mothers' communication with their early adolescents about sexual topics was not significantly associated with mothers' assessments of their early adolescents' future sexual behavior. At follow-up, mothers were more likely to talk with their adolescents about HIV prevention and birth control if they believed that their adolescents had sexually debuted, though these effects were attenuated by baseline levels of communication. Only one effect was found for adolescents' gender: mothers reported greater communication about sex with daughters. Studies are needed to determine how mothers make decisions about talking with their adolescents about sex, as well as to examine to what extent and in what instances mothers can reduce their adolescents' sexual risk behavior by providing comprehensive, developmentally appropriate sex education well before adolescents are likely to debut.

    Within the existing body of research, the information pertaining to sexual compulsivity (SC) among women, both homo- and heterosexual, remains rather limited in comparison to men. The aim of this study was to assess the prevalence of SC in a community sample of gay and bisexual men and lesbian and bisexual women and to identify differences in sexual practices based on classification as sexually compulsive within gender. Supporting previous research, the findings indicated that gay and bisexual men were significantly higher in SC when compared to lesbian and bisexual women. Similarly, sexually compulsive gay and bisexual men were more likely to report drug use with sex than their non-sexually compulsive peers, suggesting that "party n' play" may play a larger role for men with SC. In addition, the findings demonstrated empirical support for the proposition that lesbian and bisexual women with symptoms of SC were more likely to engage in specialized sexual behaviors in comparison to their non-sexually compulsive peers. These data suggest that SC manifests differently in gay, lesbian, and bisexual men and women.

    While the media have been used effectively to promote sexual responsibility in other countries for decades, few such opportunities have been seized in the United States. Mass media may be especially useful for teaching young people about reproductive health because elements of popular culture can be used to articulate messages in young people s terms, in language that won t embarrass them and may even make safe sex more attractive. Media can potentially change the way people think about sex, amidst cultural pressures to have sex at a young age, to have sex forcefully, or to have unsafe sex. Information can be communicated through a variety of channels--small media (e.g., pamphlets, brochures, and the Internet) and mass media--and in a variety of formats--campaigns, news coverage, and educational messages inserted into regular entertainment programming. Several international studies show that exposure to family planning messages through television, radio, and print media are strongly associated with contraceptive use. Domestically, safe sex media campaigns have been associated with increased teen condom use with casual partners, and reductions in the numbers of teenagers reporting sexual activity. Due to private ownership and First Amendment concerns, U.S. sexual health advocates have been working with the commercial media to incorporate subtle health messages into existing entertainment programming.

    This study examined sexual risk behaviors and sexual refusal assertiveness in relationship to child sexual abuse, emotion dysregulation, and adult sexual revictimization. Path analyses of 1,094 survivors who had sex in the past year were done to examine sexual risk behavior and sexual refusal assertiveness mediational pathways by which child sexual abuse severity and emotion dysregulation may affect revictimization over one year in adult female sexual assault survivors. Exchanging sex for money and sexual refusal assertiveness were significantly associated with emotion dysregulation, whereas exchanging sex for money, and not sexual refusal assertiveness, was only significantly related to child sexual abuse severity. Both exchanging sex for money and sex refusal assertiveness mediated the relationship between emotion dysregulation and adult sexual revictimization. Exchanging sex for money mediated the child sexual abuse severity-revictimization relationship. These findings demonstrate the importance of considering both risky and protective sexual behaviors in research and prevention programming that address sexual revictimization in women. PMID:25942287

    To further the understanding of the relationship between social class and sexual attitudes and behavior, we present data from a study of undergraduate students. We look at the education of students' fathers and how it relates to students' sexual profiles. Among the men, some traditional social class differences are found, indicating that class differences persist among some upwardly mobile men. For the women, fewer social class differences appear. Further, we compare our 1992 sample of 554 college students, 19-22 years old, with a university sample of 904 similar age students from 1967, and find our sample more coitally experienced. College students today are following norms that in the past were associated with a lower educational level. Implications of our findings for class convergence theory are addressed. Reliable birth control, gains in equality by women, and the sexual images of television and other media are discussed as major factors contributing to the increased sexual permissiveness among university students of the 1990s.

    The current study aimed to (1) offer a large-scale enumeration of college students' lifetime sexual behaviors and sexual behaviors at last event, and (2) apply a gender discrepancy lens to college students' sexual behaviors in order to examine potential gender differences in heterosexual college students' experiences. Nine-hundred and seventy college students between the ages of 18 and 27 from two large universities in the United States participated in the current study. Participants filled out a paper-pencil questionnaire during the last 30 min of class. Measures of lifetime sexual behaviors and engagement in behaviors at last sexual event were replicated from the National Survey of Sexual Health Behavior. Most college students engaged in some form of sexual behavior (manual, oral, vaginal-penile, anal). Men more frequently reported engaging in receptive sexual behaviors (e.g., receiving oral sex) where as women were more likely to engage in performative sexual behaviors (e.g., performing oral sex). At most recent sexual event, men were more likely than women to report being the sexual initiator. Findings highlight gender differences in sexual behavior and provide a foundation for social norms interventions. Holistic sexual health promotion for young adults includes acknowledging and discouraging sites of disparity in equity and pleasure. Therefore, college-level sexual health educators should pay attention to the potential pleasure gap between men and women in heterosexual encounters, and to see pleasure as an important part of sexual health that should be included in social norms campaigns.

  1. Childhood and Adolescent Sexual Abuse and Subsequent Sexual Risk Behavior: Evidence from Controlled Studies, Methodological Critique, and Suggestions for Research

    2008-01-01

    Childhood and adolescent sexual abuse (CSA) is associated with a wide variety of adverse psychological and health outcomes, including negative sexual health outcomes. In this paper, we review the literature investigating the relation between CSA and subsequent sexual risk behaviors among men and women. Previous research has found a relatively consistent association between CSA and higher rates of sexual risk behaviors, particularly sex trading, more sexual partners, and an earlier age of first intercourse. However, there are a number of limitations to this research, including lack of a consistent definition of CSA, failure to investigate gender as a moderator, and possible confounding of the CSA experience with some of the sexual behavior outcome variables. Further, although there appears to be an association between CSA and later sexual risk behavior, researchers have not established whether this association is causal. Suggestions for future research and implications for clinical practice are discussed. PMID:18045760

    Epidemiological studies find a positive association between physical and sexual abuse, neglect, and witnessing violence in childhood and same-sex sexuality in adulthood, but studies directly assessing the association between these diverse types of maltreatment and sexuality cannot disentangle the causal direction because the sequencing of maltreatment and emerging sexuality is difficult to ascertain. Nascent same-sex orientation may increase risk of maltreatment; alternatively, maltreatment may shape sexual orientation. Our study used instrumental variable models based on family characteristics that predict maltreatment but are not plausibly influenced by sexual orientation (e.g., having a stepparent) as natural experiments to investigate whether maltreatment might increase the likelihood of same-sex sexuality in a nationally representative sample (n = 34,653). In instrumental variable models, history of sexual abuse predicted increased prevalence of same-sex attraction by 2.0 percentage points (95% confidence interval [CI] = 1.4, 2.5), any same-sex partners by 1.4 percentage points (95% CI = 1.0, 1.9), and same-sex identity by 0.7 percentage points (95% CI = 0.4, 0.9). Effects of sexual abuse on men’s sexual orientation were substantially larger than on women’s. Effects of non-sexual maltreatment were significant only for men and women’s sexual identity and women’s same-sex partners. While point estimates suggest much of the association between maltreatment and sexual orientation may be due to the effects of maltreatment on sexual orientation, confidence intervals were wide. Our results suggest that causal relationships driving the association between sexual orientation and childhood abuse may be bidirectional, may differ by type of abuse, and may differ by sex. Better understanding of this potentially complex causal structure is critical to developing targeted strategies to reduce sexual orientation disparities in exposure to abuse. PMID:22976519

    Sexuality is a fundamental quality of human life, important for health, happiness, individual development, and indeed for the preservation of the human race. During the dynamic period of adolescence in which the passage from childhood to maturity takes place, sexuality takes on new dimensions; feelings become more intense, relationships become more complex, and the consequences of sexual behavior are radically altered. This not only affects the behavior of young people but also of those who interact with them, their families and peers, and those who work in the health, education, youth, social welfare, and other sectors. In the contemporary world the conditions of life for many young people have also changed, and with it patterns of sexual behavior. In general, earlier puberty, later marriage, a decline in the family leading to less control and more autonomy, and intense exposure to sexual stimuli via the mass media and travel across cultural boundaries have made pre-marital adolescent sexual activity more common. This has added to traditional problems of early marriage, newer problems of early pregnancy, childbirth, and induced abortion outside of marriage, sexually transmitted diseases, and human immunodeficiency syndrome infection leading to acquired immunodeficiency syndrome. But the work of the World Health Organization (WHO), along with many others in the field, strongly suggests that given appropriate information and services, trust and equity between the sexes, young people will behave responsibly and well. In this paper some of the findings from methods developed by WHO for research, training, advocacy, and evaluation, and findings in relation to patterns and determinants of sexual and reproductive health and development will be described, and future directions suggested.

    2013-04-01

    There is considerable interest in relations between sexual behavior and romantic attachment styles in adolescence as attachment needs are increasingly met through intimate partners rather than parents. The objectives of this research were to organize a measure of sexual behavior within an attachment theory framework, and then show that this new measure uniquely predicted sexual approach styles and invasive sexual experiences. 190 18- and 19-year-old university students in late adolescence completed sexual behavior items that were provided ambivalent (anxious) and avoidant dimensions. These were systematically related to the romantic attachment dimensions of the Experiences in Close Relationships - Revised. However, even after romantic relationship style, gender, and social desirability were controlled, avoidance in sexual relationships predicted lifetime sexual partner number and negatively predicted positive sexual strategies, and ambivalence in sexual relationships predicted invasive and coercive sexual behaviors. A measure specific to sexual relationships informs the attachment and romantic context of sex in late adolescence.

    Moore, Sarah R; Harden, K Paige; Mendle, Jane

    Girls who experience earlier pubertal timing relative to peers also exhibit earlier timing of sexual intercourse and more unstable sexual relationships. Although pubertal development initiates feelings of physical desire, the transition into romantic and sexual relationships involves complex biological and social processes contributing both to physical maturation and to individual interpretations of pubertal experiences. Using a sample of female sibling pairs (n = 923 pairs) from the National Longitudinal Study of Adolescent Health, the present study investigated associations among menarche and perceived pubertal timing, age of first sexual intercourse (AFI), and adolescent dating and sexual behavior using a behavioral genetic approach. Genetic factors influencing age at menarche and perceived pubertal timing predicted AFI through shared genetic pathways, whereas genetic factors related only to perceived pubertal timing predicted engagement in dating, romantic sex, and nonromantic sex in the previous 18 months. These results suggest that a girl's interpretation of her pubertal timing beyond objective timing is important to consider for the timing and the contexts of romantic and reproductive behavior.

    Out of control sexual behavior, also known as compulsive sexual behavior or sexual addiction, has not been studied in a representative sample of the general population. At age 32 years, 940 (93%) of 1,015 members of the birth cohort of the Dunedin Multidisciplinary Health and Development Study responded to a series of questions about sexual behavior, administered by computer. We enquired about sexual fantasies, urges or behavior that participants regarded as out of control during the previous year, and defined such experiences as out of control sexual experiences (OCSE). Nearly 13% of men and 7% of women reported OCSE in the past year. Women who reported such experiences were more likely than other women to have reported (elsewhere in the interview) having had high numbers of opposite sex partners, concurrent sexual relationships, or sex with a partner met on the internet, as well as a higher likelihood of same-sex attraction or behavior. Among men reporting OCSE, there was an association with having paid for heterosexual sex and with same-sex attraction and behavior. Few believed that OCSE had interfered with their lives (3.8% of all men and 1.7% of all women in the cohort). Only 0.8% of men and 0.6% of women reported that their actual sexual behavior had interfered with their lives. OCSE were also analyzed in relation to certain personality traits and to childhood sexual abuse (CSA). Some evidence of a link with impulsivity (women only) and negative affectivity was found. CSA was associated with OCSE among men. In conclusion, this population-based study has provided the first empirical estimations of the occurrence of OCSE and its relationship to a range of sexual behaviors in a representative sample.

    There is an endocrinological concern that environmental endocrine disrupters (EEDs) may influence sexual differentiation. Bisphenol A (BPA), one of EEDs, is released from polycarbonate plastics, and has been detected in the human umbilical cord. In this study, we examined the effect of BPA on the sexual differentiation of open-field behavior and the sexually dimorphic nuclei in the brain in the offspring of rats exposed to BPA during the fetal and suckling periods at a dosage below the human tolerable daily intake (TDI) level. In the control group, females were more active in the open field and had a larger locus coeruleus (LC) volume than males. BPA abolished and inverted the sex differences of the open-field behavior and the LC volume, respectively, without affecting the reproductive system. We also compared the effects of estrogenic compounds, diethylstilbestrol (DES) and resveratrol (RVT), to that of BPA because of their structural similarities. DES affected the open-field behavior, LC volume and reproductive system, while RVT affected the LC volume and the reproductive system. These results suggest that the brain is highly sensitive to BPA at a dosage below TDI and that the disrupting effects of BPA on sexual differentiation may vary from those of RVT and DES.

    This study assessed Kinsey self-ratings and lifetime sexual experiences of 17-year-olds whose lesbian mothers enrolled before these offspring were born in the longest-running, prospective study of same-sex parented families, with a 93% retention rate to date. Data for the current report were gathered through online questionnaires completed by 78 adolescent offspring (39 girls and 39 boys). The adolescents were asked if they had ever been abused and, if so, to specify by whom and the type of abuse (verbal, emotional, physical, or sexual). They were also asked to specify their sexual identity on the Kinsey scale, between exclusively heterosexual and exclusively homosexual. Lifetime sexual behavior was assessed through questions about heterosexual and same-sex contact, age of first sexual experience, contraception use, and pregnancy. The results revealed that there were no reports of physical or sexual victimization by a parent or other caregiver. Regarding sexual orientation, 18.9% of the adolescent girls and 2.7% of the adolescent boys self-rated in the bisexual spectrum, and 0% of girls and 5.4% of boys self-rated as predominantly-to-exclusively homosexual. When compared with age- and gender-matched adolescents of the National Survey of Family Growth, the study offspring were significantly older at the time of their first heterosexual contact, and the daughters of lesbian mothers were significantly more likely to have had same-sex contact. These findings suggest that adolescents reared in lesbian families are less likely than their peers to be victimized by a parent or other caregiver, and that daughters of lesbian mothers are more likely to engage in same-sex behavior and to identify as bisexual.

    The aim of this study was to investigate the effects of ethanolic extract of Pueraria tuberosa (PT) on sexual behaviour and androgenic activity. Male albino rats were divided into four groups of six animals each: control group 1 (2% acacia solution), PT-treated group 2 (50 mg/Kg), PT-treated group 3 (100 mg/Kg), and PT-treated group 4 (150 mg/Kg). Sexual behavior of male rats in the presence of a female rat was recorded. The treated groups were evaluated for sexual parameters. The extract was characterized using LC-MS. The effect of treatment on anabolic and weight of secondary sexual organs was determined. The histological changes in section of testis and epididymis after treatment were observed. Sperm count in epididymis and fructose content in seminal vesicles were also measured. Levels of hormones like FSH, LH, and T were determined. A dose-dependent increase in sexual behaviors was evidenced in the animals of extract treated groups. Increase in testis weight was recorded in PT. At the highest dose PT also affects the hormones level. The four compounds namely puerarin, daidzein, biochanin-A and formononetin were identified in ethanolic extract using LC-MS. It concluded that PT extract possesses androgenic effect and it significantly increased the sexual behaviour and hormones level. PMID:24489512

    Childhood sexual abuse (CSA) is associated with HIV sexual risk behavior. Although many psychosocial correlates of sexual risk among HIV-positive persons have been identified, studies predicting continued risk among HIV-positive adults with histories of CSA are limited. This cross-sectional study identified variables predictive of sexual transmission risk behavior among an ethnically diverse sample of 256 HIV-positive adults (women and men who have sex with men; MSM) with CSA histories. Participants were assessed for trauma symptoms, shame related to HIV and sexual trauma, substance use, coping style, and sexual risk behavior. Logistic regression analyses were conducted to identify variables predictive of unprotected sexual behavior in the past 4 months. Unprotected sex was significantly associated with substance use and trauma-related behavioral difficulties among women and men, and less spiritual coping among men. Unprotected sex with HIV negative or serostatus unknown partners was significantly associated with greater trauma-related behavioral difficulties, more HIV-related shame, and fewer active coping strategies. Thus, trauma symptoms, shame, coping style, and substance use were significantly associated with sexual risk behavior among HIV-positive adults with histories of CSA, with models of prediction differing by gender and partner serostatus. HIV prevention intervention for persons with HIV and CSA histories should address trauma-related behavioral difficulties and enhance coping skills to reduce sexual transmission risk behavior.

  20. Sexual behavior and social education in China.

    The application on a massive scale of various population, family planning, sex education measures in China is a societal feature that is quickly evident to the country's visitors. For anyone concerned with population limitation on a national scale, the Chinese experiments and progress are of particular interest. In China there is a clearly discernible 3 step program: the minimization of sexual interest or enforced "national abstinence standard" in the teen years; a period of intense propaganda to postpone marriage until the mid 20s and avoid sexual intercourse outside marriage; and a concerted educational campaign aimed predominantly at married females for the 20 year span covering the fertile ages of approximately 25-45 to limit families. The Chinese approach to family planning and sexual education is direct and ubiquitous. One of the more paradoxical aspects of China's campaign to enforce their severe and particular natalist policy is the relatively high level of preventive sex knowledge among young married couples and the virtual absence of any major form of sex education for teenagers in the schools. In the past few years there has been a modest yet detectable change in this approach. Some middle school students are now being introduced, albeit on a sexually segregated basis, to somewhat wider aspects of population knowledge and human population studies. For the most part these units fall into the traditional teaching areas utilized in many western nations, i.e., physiology, biology, and physical education courses. The development and expansion of such courses may foreshadow the gradual introduction nationally of new material into the middle schools, but the predominant aim of sex education will remain the limitation and control of population. Some of the answers to sex education questions posed by this author in various schools and to a range of senior education officials are reported. The answers represent a recent sample, extracted from a number gathered

  1. “Sexting” and its relation to sexual activity and sexual risk behavior in a national survey of adolescents

    2014-01-01

    Objective To examine the relation between “sexting,” (sending and sharing sexual photos online via text messaging and in-person) with sexual risk behaviors and psychosocial challenge in adolescence. Methods Data were collected online between 2010 and 2011 with 3,715 randomly selected 13- to 18-year-old youth across the United States. Results Seven percent of youth reported sending or showing someone sexual pictures of themselves, where they were nude or nearly nude, online, via text messaging, or in-person, during the past year. Although females and older youth were more likely to share sexual photos than males and younger youth, the profile of psychosocial challenge and sexual behavior was similar for all youth. After adjusting for demographic characteristics, sharing sexual photos was associated with all types of sexual behaviors assessed (e.g., oral sex, vaginal sex) as well as some of the risky sexual behaviors examined—particularly having concurrent sexual partners and having more past-year sexual partners. Adolescents who shared sexual photos also were more likely to use substances and less likely to have high self-esteem than their demographically similar peers. Conclusions While the media has portrayed “sexting” as a problem caused by new technology, health professionals may be more effective by approaching it as an aspect of adolescent sexual development and exploration and, in some cases, risk-taking and psychosocial challenge.

    This study focused on the sexual phenomenon of “hooking-up.” A hook-up is defined as a single sexual encounter that may or may not include sexual intercourse with someone who is a stranger, brief acquaintance, or friend. The aim of this study was to document the prevalence of hook-ups in a sample of 1,011 urban, middle and high school students and to examine the relationship between hooking-up and a variety of problem behaviors, including, alcohol, cigarette, illicit drug use, truancy, and school suspensions. The results revealed that 28% of the sample had engaged in at least one hook-up experience, and this percentage increased with age. Hook-ups were correlated moderately with all problem behaviors examined. PMID:22039333

    Background: Intimate partner violence (IPV) and risky sexual behaviors are serious and overlapping public health problems that disproportionately affect drug-involved women. Despite the fact that drug-using women experience extensive IPV, to date, no studies have investigated the association of IPV and risky sexual behaviors among drug-using women in Iran. Methods: Drug-using women (N =120) were recruited from a rehabilitation center in Tehran from March to October, 2009. The Revised Conflict Tactics Scale (CTS2), a standardized questionnaire, was used to collect data regarding violence. We used t-test and logistic regression models to explore the relationship between IPV domains and specific sexual risk behavior outcomes using SPSS 21. Results: The means (sd) for CTS2 domains were as follows: negotiation 4.29 (1.55), psychological violence 2.55 (1.51), sexual violence 0.37 (1.00), physical abuse 1.17 (1.49), injury 2.18 (1.97), and the mean total score was 1.69 (0.96). We found significantly higher injury scores, but lower sexual abuse scores among women with sexually-transmitted infection (STI) compared to women without STI (p-values 0.030 and <0.0001, respectively). In addition, we found that psychological abuse was positively associated with STI (p-value 0.03) and increased condom use (p = 0.010), possibly mediated through an increased likelihood of having multiple partners. Conclusion: The findings revealed that in Iran drug-involved women experience high rates of IPV and that IPV is associated with increased risky sexual behavior. Implication: Preventive interventions for violence that are integrated within drug treatment programs, as well as harm reduction programs are highly recommended. PMID:26034727

    Sexual behavior may be altered during pregnancy. The authors aimed to investigate the behavior of pregnant women in terms of level of sexual initiative and change in sexual positions for intercourse. The authors conducted a retrospective research with 156 pregnant Brazilian women who completed a questionnaire. Before pregnancy, both partners usually initiated sex, whereas during pregnancy, the male partner generally did. In general, women who took the sexual initiative showed better scores in the sexuality variables. During pregnancy, the use of each sexual position reduced significantly. Couples in which both partners take the sexual initiative tend to accept a wider variety of sexual positions.

    Kinsey's findings regarding the sexual behavior of black women were compared with data from a more recent study of sexual socialization and experiences among women in Los Angeles County, Ca. The study examined responses from two groups of college-educated black women, ages 18 to 36, 196 women from the original Kinsey sample and 64 women from the new sample. Log-linear analyses were used to control for differences between the samples on age and marital status. Comparisons were conducted in the areas of childhood family characteristics; sexual socialization and education; sexual behavior in childhood, adolescence, and adulthood; contraceptive practices; and child sexual abuse. Results reflected changes that have taken place in society and in patterns of sexual behavior. Differences in sexual socialization pointed to the increased role of the media and the schools and to more relaxed attitudes about nudity in the home. Shifts in sexual behavior were particularly dramatic. As compared to women in the Kinsey sample, newer subjects began intercourse earlier, were less likely to have a fiance or husband as their first partner, reported a higher number of sexual partners, and participated in a broader range of sexual behaviors. Contraceptive practices differed considerably, especially among never-married women. Women in this study were slightly more likely to report instances of child sexual abuse. Methodological and social factors contributing to the findings are discussed. PMID:3421826

    Sexually compulsive/addictive behavior is a pattern of sexual behaviors that cause distress and/or impairment of social functioning. It is marked by obsessive thoughts, compulsive behaviors, and the individual's inability to stop the behaviors despite negative consequences. Women experiencing sexually compulsive/addictive behavior are preoccupied with sex not as a response to desire but rather as a behavior that serves the purpose of anxiety reduction. Sexually compulsive/addictive behavior is associated with a number of health consequences, including sexually transmitted infections, unwanted pregnancies, abortions, and violence. It is important for providers to have an understanding of the addiction process, assessment, diagnosis, and interventions for these women.

  12. On sexual behavior and sex-role reversal.

    PubMed

    Schuiling, Gerard A

    2005-09-01

    Sex is not about reproduction; sex is about (re-)combination of DNA. Sex, not reproduction, always involves physical contact between two individuals; to achieve this, strategies of sexual behavior evolved. Sexual behavior, therefore, did not evolve as part of a reproductive strategy, but evolved to enable exchange of genetic material. In multicellular organisms the situation is more complicated than in unicellular organisms, as it is impossible for each cell within a multicellular body to have sex with another cell. Hence, evolution selected a system in which the possibility to have sex was limited to only one cell-line: the germ cells. As a result, sex adopted the character of fertilization, and sex and reproduction became inseparably linked. Still, in some species, including humans, sexual behavior still exhibits features of its evolutionary past: in humans (like in bonobo's) most sexual activity and many sexual behavioral patterns have nothing to do with reproduction (masturbation, homosexual behavior, for example); in humans, sexual behavior also became associated with other strategic objectives, such as intensifying the pair bond, expression of love or power. Different genders - male and female - evolved, and each gender evolved typical gender-related sexual and reproductive strategies as well. In most multicellular species, these strategies became inextricably mixed, and sexual behavior increasingly more - and in most species even exclusively - 'served' the interests of reproduction: sexual behavior became more or less synonymous with reproductive behavior. In most species, the 'mix' of sexual and reproductive strategies evolved into typical gender-related patterns of behavior, that is, in typical 'sex-roles'. Often, males are bigger and more 'beautiful' (= more intensely ornamented) than females; males compete with each other for access to females; males court females, while females choose males ('female choice'). However, ecological circumstances may cause

    Prior research shows that violence is associated with sexual risk behavior, but little is known about the relation between community violence (i.e., violence that is witnessed or experienced in one's neighborhood) and sexual risk behavior. To better understand contextual influences on HIV risk behavior, we asked 508 adult patients attending a publicly funded STI clinic in the U.S. (54 % male, M age = 27.93, 68 % African American) who were participating in a larger trial to complete a survey assessing exposure to community violence, sexual risk behavior, and potential mediators of the community violence-sexual risk behavior relation (i.e., mental health, substance use, and experiencing intimate partner violence). A separate sample of participants from the same trial completed measures of sexual behavior norms, which were aggregated to create measures of census tract sexual behavior norms. Data analyses controlling for socioeconomic status revealed that higher levels of community violence were associated with more sexual partners for men and with more episodes of unprotected sex with non-steady partners for women. For both men and women, substance use and mental health mediated the community violence-sexual risk behavior relation; in addition, for men only, experiencing intimate partner violence also mediated this relation. These results confirm that, for individuals living in communities with high levels of violence, sexual risk reduction interventions need to address intimate partner violence, substance use, and mental health to be optimally effective.

    Recent evidence suggests that young sexual minority men's sexual position identities (e.g., "top," "bottom," "versatile") may be governed by dynamic influences. Yet, no study has prospectively examined whether, how, and why this aspect of sexual minority men's sexuality changes over time. Consequently, the present study investigated the extent to which young sexual minority men use sexual position identities consistently over time, typical patterns of position identity change, explanations given for this change, and the correspondence of changing sexual position identities with changing sexual behavior and fantasies. A total of 93 young sexual minority men indicated their sexual position identity, behavior, and fantasies at two assessment points separated by 2 years. Following the second assessment, a subset (n = 28) of participants who represented the various sexual position identity change patterns provided explanations for their change. More than half (n = 48) of participants changed their sexual position identity. Participants showed a significant move away from not using sexual position identities toward using them and a significant move toward using "mostly top." Changes in position identity were reflected, although imperfectly, in changes in sexual behavior and largely not reflected in fantasy changes. Participants offered 11 classes of explanations for their identity changes referencing personal development, practical reasons, changing relationships, and sociocultural influences. Previous investigations of sexual minority men's sexual position identities have not adequately attended to the possibility of the changing use of the sexual position categories "top," "bottom," and "versatile" across young adulthood. Results of the present study suggest the possibility of a more fluid, context-dependent use of these terms than previously documented.

    2010-12-01

    China has been experiencing pronounced changes in its sex ratio, but little research has explored the consequences of these changes for sexual behavior and health. We merge data from the 1999-2000 Chinese Health and Family Life Survey with community-level data from the 1982, 1990, and 2000 Chinese censuses to examine the relationship between the local sex ratio and several dimensions of men's sexual behavior and sexual health. Multilevel logistic regression models show that, when faced with a relative abundance of age-matched women in their community, Chinese men are slightly less likely to have intercourse with commercial sex workers, but are more likely to engage in premarital noncommercial intercourse and to test positive for a sexually transmitted infection. These findings are consistent with hypotheses derived from demographic-opportunity theory, which suggests that an abundance of opposite-sex partners will increase the risk of early, frequent, and multi-partner sex and, through this, sexually transmitted infection risk.

    Indigenous migrant workers (IMWs) have a high vulnerability to HIV and STDs due to poverty and marginalization. This study examined factors associated with sexual risk behavior (SRB) according to type of partner in transnational young male IMWs at a sugar cane agro-industrial complex in western Mexico. A total of 192 sexually active IMWs were recruited from four laborer shelters to participate in a sexual partner survey. The IMWs were interviewed about their sexual partners and practices over the last 12 months during which it emerged that they had had a total of 360 sexual partners. Multiple linear regression analyses were performed to identify factors related to SRB in 222 main (spouse, mistress and girlfriend) and 138 casual partners (colleague, friend, casual encounter and sex worker). Results showed a significantly higher SRB score with casual partners. For the main partner regression model, prior exposure to HIV- and STD-preventive information and sexual intercourse with higher employment status partners (formal workers vs. self-employed in informal activities and unemployed) were associated with lower SRB scores, but if the sexual relations occurred in Mexico (vs. the U.S.), the SRB scores increased. For the casual partner model, the practice of survival sex (sex in exchange for basic needs), sexual relations in Mexico (vs. the U.S.), and being a circular migrant (person traveling for temporary work to return home when the contract is over) were related to higher SRB scores. Findings support the implementation of preventive interventions using different messages depending on the type of partners, main or casual, within the labor migrant context. PMID:22851155

  2. A selective androgen receptor modulator enhances male-directed sexual preference, proceptive behavior, and lordosis behavior in sexually experienced, but not sexually naive, female rats.

    Androgens influence many aspects of reproductive behavior, including sexual preference of females for males. In oophorectomized women with sexual desire disorder, testosterone patches improve libido, but their use is limited because of adverse side effects. Selective androgen receptor modulators offer an improved safety profile for both sexes: enhancing libido and muscle and bone growth in a manner similar to steroidal androgens but with fewer adverse effects, such as hirsutism, acne, and prostate growth. The current study investigated the action of a novel selective androgen receptor modulator (LGD-3303 [9-chloro-2-ethyl-1-methyl-3-(2,2,2-trifluoroethyl)-3H-pyrrolo-[3,2-f]quinolin-7(6H)-one]) on male-directed sexual preference, proceptivity, and lordosis behavior of female rats. LGD-3303 is a nonsteroidal, nonaromatizable, highly selective ligand for the androgen receptor and effectively crosses the blood-brain barrier. Gonadectomized female rats were treated with LGD-3303 (3-30 mg/kg) or vehicle by daily oral gavage. Results showed that LGD-3303 treatment enhanced sexual preference of females for males but only if females had previous sexual experience. This occurred after 1 or 7 d of treatment. In contrast, preference for males was inhibited by LGD-3303 treatments of sexually naive females. The LGD-3303 increase in male preference was blocked by pretreatment with the androgen receptor antagonist flutamide. LGD-3303 treatment increased lordosis and proceptivity behaviors in ovariectomized females primed with suboptimal doses of estradiol benzoate plus progesterone. These data support the concept that LGD-3303 can stimulate aspects of female sexual behavior and may serve as a potential therapeutic for women with sexual desire disorders.

    Background Little is known about the sexual health behaviors of Deaf American Sign Language (ASL) users. Objective We sought to characterize the self-reported sexual behaviors of Deaf individuals. Methods Responses from 282 Deaf participants aged 18–64 from the greater Rochester, NY area who participated in the 2008 Deaf Health were analyzed. These data were compared with weighted data from a general population comparison group (N=1890). We looked at four sexual health-related outcomes: abstinence within the past year; number of sexual partners within the last year; condom use at last intercourse; and ever tested for HIV. We performed descriptive analyses, including stratification by gender, age, income, marital status, and educational level. Results Deaf respondents were more likely than the general population respondents to self-report two or more sexual partners in the past year (30.9% vs 10.1%) but self-reported higher condom use at last intercourse (28.0% vs 19.8%). HIV testing rates were similar between groups (47.5% vs 49.4%) but lower for certain Deaf groups: Deaf women (46.0% vs. 58.1%), lower-income Deaf (44.4% vs. 69.7%) and among less educated Deaf (31.3% vs. 57.7%) than among respondents from corresponding general population groups. Conclusion Deaf respondents self-reported higher numbers of sexual partners over the past year compared to the general population. Condom use was higher among Deaf participants. HIV was similar between groups, though HIV testing was significantly lower among lower-income, less well-educated, and female Deaf respondents. Deaf individuals have a sexual health risk profile that is distinct from that of the general population. PMID:26242551

    Perinatal exposure to bisphenol A (BPA, 0.1 and 1 ppm in drinking water applied to mother rats for 6 weeks) has been shown to impair the sexual differentiation in exploratory behavior, but the exact critical period of this disrupting effect is still unknown. In this study, we examined the effects of prenatal exposure to BPA (0.1 ppm in drinking water applied to dams during the final week of pregnant) on emotional and learning behaviors in addition to exploratory behavior. Estimated daily intake was 15 microg/kg/day, below the reference dose (RfD) in the United States and the daily tolerable intake (TDI) in Japan (50 microg/kg/day). The rats were successively tested in open-field test, elevated plus maze test, passive avoidance test and forced swimming test during development from 6 to 9 weeks of juvenile period. Prenatal exposure to BPA mainly affected male rats and abolished sex differences in rearing behavior in the open-field test and struggling behavior in the forced swimming test. BPA increased the immobility of male rats in the forced swimming test. The avoidance learning and behaviors in the elevated plus maze were not affected. The present study demonstrates that male rats at the final week of prenatal period are sensitive to BPA, which impairs sexual differentiation in rearing and struggling behavior and facilitate depression-like behavior.

    Background The epidemic of HIV continues to grow in Nigeria. Personnel in the military are at increased risk of HIV infection. Although HIV-risk related sexual behavior of Nigerian police officers has been studied, little is known about the sexual behavior of their counterparts in the Navy. This study describes knowledge of AIDS, and HIV-risk sexual behavior of naval personnel in Lagos Nigeria. Methods Four hundred and eighty personnel of the Nigerian Navy completed a 70-item questionnaire in 2002. Group discussion and in-depth interviews of four key informants were also conducted to gain insights into the context of risky sexual behaviors and suggestions for feasible HIV primary prevention interventions. Results The mean age of the respondents was 34 years. Although the overall mean AIDS knowledge score was 7.1 of 10 points, 52.1% of respondents believed that a cure for AIDS was available in Nigeria and that one can get HIV by sharing personal items with an infected person (25.3%). The majority (88.1%) had had lifetime multiple partners ranging from 1–40 with a mean of 5.1; 32.5% of male respondents had had sexual contact with a female sex worker, 19.9% did so during the six months preceding the survey. Forty-one percent of those with sexual contact with a female sex worker did not use a condom during the most recent sexual encounter with these women. Naval personnel who have been transferred abroad reported significantly more risky sexual behaviors than others. Group discussants and key informants believed that sex with multiple partners is a tradition that has persisted in the navy even in the era of AIDS because of the belief that AIDS affects only foreigners, that use of traditional medicine provides protection against HIV infection, and influence of alcohol. Conclusion Many naval personnel report participating in high-risk sexual behavior which may increase their risk of acquiring and spreading HIV. Naval personnel live and interact freely with civilian

    Objective To assess longitudinal trajectories of college males’ sexually aggressive behaviors and determine time-varying individual- and peer-level risk factors that differentiate men who follow these different paths. Method Our analytic sample consisted of 795 men who participated in a longitudinal study on high-risk behaviors among college students. The sample was surveyed at the end of each of their four years at university on a variety of measures, including sexual aggression (SA) and its hypothesized risk factors (hostile masculinity, number of sexual partners, alcohol misuse, and peer norms). Results Using latent growth mixture modeling, we found four distinct SA trajectories – (1) consistently high, (2) decreasing, (3) increasing, and (4) consistently low. Multinomial logistic regression revealed that hostile masculinity and peer norms positively predicted trajectory membership at times when each trajectory reflected a high level of SA. Conclusions Our study adds to the knowledge base by elucidating the different ways sexually aggressive behaviors change during emerging adulthood and how confluence model-derived factors predict the different trajectories. The finding that changes over time in these risk factors correspond with SA perpetration risk informs prevention programming by illuminating the importance of continual focus on these risk factors throughout the college years, perhaps through annual self-assessments.

    Evidence is accumulating that sex steroids in the eggs, besides affecting progeny phenotype and behavior in the short term, also have enduring effects until adulthood, when they may translate into differences in reproductive strategies and success. Maternal steroids transfer may therefore affect both agonistic behavior and mate choice decisions, either through the promotion of body size and condition or through a priming effect on the neuroendocrine system. However, owing to the prevalence of a short-term perspective, relevance of maternal transfer of sex steroids to sexual selection processes has been seldom studied. Here we investigate the effects of an experimental increase in egg testosterone on male dominance and copulation success in the ring-necked pheasant, Phasianus colchicus, a polygynous galliform with multiple male ornamental traits, in captivity. We found that females from testosterone (T) injected eggs copulated less than control females. Males from T-injected eggs obtained more copulations than control males, specifically with control females. The effect of male 'ordinary' and secondary sexual traits on either dominance or copulation frequency did not depend on early exposure to T, nor did T treatment affect male dominance. Present results demonstrate that variation in the early hormonal environment set up by mothers affects sexual behavior of the offspring, which might translate into fitness differences.

    Female college students reporting a history of childhood sexual abuse (N=175) and not reporting a history of childhood sexual abuse (N=260) were compared on indices of six self-destructive behaviors, including drug use, alcohol abuse, binge eating, self-mutilation, risky sex, and suicidality. The samples were also compared on two measures of dissociation, the Trauma Symptom Checklist dissociation subscale and the Dissociative Experiences Scale. The CSA group had significantly higher mean scores on all the indices of self-destructive behavior except self-mutilation (where the mean difference approached significance), and on both measures of dissociation. One or both dissociation measures were related significantly to each index of self-destructive behavior except binge eating. Multiple regression mediation analyses provided support for the hypothesis that dissociation mediates the relationships between CSA and both drug use and alcohol abuse. Dissociation also explained significant variability when added to the regressions of risky sex and suicidality on CSA.

    Life History Theory (LHT), a branch of evolutionary biology, describes how organisms maximize their reproductive success in response to environmental conditions. This theory suggests that challenging environmental conditions will lead to early pubertal maturation, which in turn predicts heightened risky sexual behavior. Although largely confirmed among female adolescents, results with male youth are inconsistent. We tested a set of predictions based on LHT with a sample of 375 African American male youth assessed three times from age 11 to age 16. Harsh, unpredictable community environments and harsh, inconsistent, or unregulated parenting at age 11 were hypothesized to predict pubertal maturation at age 13; pubertal maturation was hypothesized to forecast risky sexual behavior, including early onset of intercourse, substance use during sexual activity, and lifetime numbers of sexual partners. Results were consistent with our hypotheses. Among African American male youth, community environments were a modest but significant predictor of pubertal timing. Among those youth with high negative emotionality, both parenting and community factors predicted pubertal timing. Pubertal timing at age 13 forecast risky sexual behavior at age 16. Results of analyses conducted to determine whether environmental effects on sexual risk behavior were mediated by pubertal timing were not significant. This suggests that, although evolutionary mechanisms may affect pubertal development via contextual influences for sensitive youth, the factors that predict sexual risk behavior depend less on pubertal maturation than LHT suggests.

    The study sought to determine whether maltreatment subtypes, family sexuality, and personal characteristics predicted and distinguished child problematic sexual behaviors (PSB) and externalizing problems (EP). Participants were families of 188 children, 6-11 years old, referred by child welfare services in four Quebec districts. Caregivers completed interviews and questionnaires. Results suggested that family environment and maltreatment subtypes had partially different impacts on PSB and EP. When EP and gender were controlled, younger children in a sexualized family environment and those verbally victimized were more likely to exhibit PSB. When PSB and gender were controlled, verbal abuse and neglect emerged as predictors of EP. Potential implications for child PSB research and interventions are discussed. PMID:20718000

    Research on the sexuality of Asians and Latinos in the United States has been sparse, and the studies that have been done suffer from a number of limitations. Using data from the National Latino and Asian American Study (2002-2003), this study examined self-identified sexual orientation and self-reported sexual behavior among Latinos (n = 2,554; age: M = 38.1, SE = 0.5) and Asians (n = 2,095; age: M = 41.5, SE = 0.8). This study also investigated implications for unfair treatment and psychological distress among sexual minorities identified in the sample. Results indicated heterogeneity in responses to items assessing sexual orientation and sexual behavior including differences in the adoption of lesbian, gay, or bisexual (LGB) identity by gender, ethnicity, nativity, and socioeconomic status. LGB sexual minorities reported higher levels of unfair treatment and psychological distress compared to their non-LGB-identified sexual minority counterparts, and unfair treatment was positively associated with psychological distress. Results highlight the need to consider multiple demographic factors in assessing sexuality, and also suggest that measures of both self-identified sexual orientation and sexual behavior should be collected. In addition, findings provide support for the deleterious influence of unfair treatment among Asians and Latinos in the United States.

    Prior research has established an association between sexual violence and HIV. Exposure to sexual violence during childhood can profoundly impact brain architecture and stress regulatory response. As a result, individuals who have experienced such trauma may engage in sexual risk-taking behavior and could benefit from targeted interventions. In 2009, nationally representative data were collected on violence against children in Tanzania from 13-24 year old respondents (n=3,739). Analyses show that females aged 19-24 (n=579) who experienced childhood sexual violence, were more likely to report no/infrequent condom use in the past 12 months (AOR=3.0, CI [1.5, 6.1], p=0.0017) and multiple sex partners in the past 12 months (AOR=2.3, CI [1.0, 5.1], p=0.0491), but no more likely to know where to get HIV testing or to have ever been tested. Victims of childhood sexual violence could benefit from targeted interventions to mitigate impacts of violence and prevent HIV.

    Although research has repeatedly demonstrated that adolescents' use of sexually explicit Internet material (SEIM) is related to their endorsement of permissive sexual attitudes and their experience with sexual behavior, it is not clear how linkages between these constructs unfold over time. This study combined 2 types of longitudinal modeling, mean-level development and cross-lagged panel modeling, to examine (a) developmental patterns in adolescents' SEIM use, permissive sexual attitudes, and experience with sexual behavior, as well as whether these developments are related; and (b) longitudinal directionality of associations between SEIM use on the 1 hand and permissive sexual attitudes and sexual behavior on the other hand. We used 4-wave longitudinal data from 1,132 7th through 10th grade Dutch adolescents (M(age) T1 = 13.95; 52.7% boys) and estimated multigroup models to test for moderation by gender. Mean-level developmental trajectories showed that boys occasionally and increasingly used SEIM over the 18-month study period, which co-occurred with increases in their permissive attitudes and their experience with sexual behavior. Cross-lagged panel models revealed unidirectional effects from boys' SEIM use on their subsequent endorsement of permissive attitudes, but no consistent directional effects between their SEIM use and sexual behavior. Girls showed a similar pattern of increases in experience with sexual behavior, but their SEIM use was consistently low and their endorsement of permissive sexual attitudes decreased over the 18-month study period. In contrast to boys, girls' SEIM use was not longitudinally related to their sexual attitudes and behavior. Theoretical and practical implications of these gender-specific findings are discussed.

    Sexually transmitted infections (STIs) continue to present a complex and costly challenge to public health programs. The preferences and social dynamics of a population can have a large impact on the course of an outbreak as well as the effectiveness of interventions intended to influence individual behavior. In addition, individuals may alter their sexual behavior in response to the presence of STIs, creating a feedback loop between transmission and behavior. We investigate the consequences of modeling the interaction between STI transmission and prophylactic use with a model that links a Susceptible-Infectious-Susceptible (SIS) system to evolutionary game dynamics that determine the effective contact rate. The combined model framework allows us to address protective behavior by both infected and susceptible individuals. Feedback between behavioral adaptation and prevalence creates a wide range of dynamic behaviors in the combined model, including damped and sustained oscillations as well as bistability, depending on the behavioral parameters and disease growth rate. We found that disease extinction is possible for multiple regions where R0>1, due to behavior adaptation driving the epidemic downward, although conversely endemic prevalence for arbitrarily low R0 is also possible if contact rates are sufficiently high. We also tested how model misspecification might affect disease forecasting and estimation of the model parameters and R0. We found that alternative models that neglect the behavioral feedback or only consider behavior adaptation by susceptible individuals can potentially yield misleading parameter estimates or omit significant features of the disease trajectory.

  17. Sexual dysfunction in epilepsy.

    PubMed

    Morrell, M J

    1991-01-01

    Sexual dysfunction may arise more frequently in men and women with epilepsy than with other chronic illnesses, manifesting primarily as diminished sexual desire and potency. Studies using retrospective self-report of sexual attitude and behavior find an incidence of sexual dysfunction ranging from 14-66%. Sexual dysfunction may be more common in partial than in generalized epilepsies. Sexual dysfunction in epilepsy may result from a disturbance in social or psychological factors affecting sexual responsiveness. Alternatively, epileptiform discharges may disrupt the function of structures mediating sexual behavior, particularly the limbic cortex, or alter the release of hypothalamic or pituitary hormones. Antiepileptic drugs modulate hormone release from the hypothalamic-pituitary-gonadal axis and may have direct inhibitory effects on sexual behavior. Evidence both supports and refutes each of these etiologies in the sexual dysfunction seen with epilepsy. Specific evaluation and treatment protocols for patients with sexual dysfunction are available.

    The discipline of behavioral economics integrates principles from psychology and economics to systematically characterize decision-making preferences. Two forms of behavioral economic decision making are of relevance to HIV risk behavior: delay discounting, reflecting preferences for immediate small rewards relative to larger delayed rewards (i.e., immediate gratification), and probability discounting, reflecting preferences for larger probabilistic rewards relative to smaller guaranteed rewards (i.e., risk sensitivity). This study examined questionnaire-based indices of both types of discounting in relation to sexual risk taking in an emergency department sample of hazardous drinkers who engage in risky sexual behavior. More impulsive delay discounting was significantly associated with increased sexual risk-taking during a drinking episode, but not general sexual risk-taking. Probability discounting was not associated with either form of sexual risk-taking. These findings implicate impulsive delay discounting with sexual risk taking during alcohol intoxication and provide further support for applying this approach to HIV risk behavior. PMID:25267115

    Similarities as well as differences across species in the control of sexual behavior are helping to fully understand the subtle relations between physiology and eco-ethological constraints and how the brain integrates such information. We will illustrate this with sexual behavior in domestic ruminants and especially ewes. Females of these species like humans, but unlike rodents, have a long luteal phase. A prolonged exposure to progesterone (Pg) before the preovulatory estradiol rise is necessary for estrous behavior to be displayed. Estradiol action and receptor localization is very similar to that observed in other species. But not too surprisingly, the role of Pg is rather different with a priming effect not observed in rodents. However, as in rodents, Pg also has an inhibitory effect, is necessary for the display of proceptivity and is responsible for the timing of the different periovulatory events. These steroids act on the central nervous system in similar areas across mammalian species to regulate estrous behavior. Steroid fluctuations during the estrous cycle cause changes in catecholaminergic activity in the hypothalamus. Interestingly, these neurotransmitters seem to have very similar effects in ewes and rats as illustrated by the norepinephrine rise after male-female interactions observed in both species. Similar comparisons can be made regarding the action of some neuropeptides, including oxytocin and GnRH, and more integrative processes like sexual differentiation and modulation of reproduction by social interactions. Data on sheep, goats and cows will be compared with those of rodents. PMID:17499740

    This study tested the Theory of Reasoned Action to examine the prediction of early sexual behavior among African American young teen girls. Baseline data from a longitudinal randomized clinical trial were used. Between 2001 and 2005, 198 middle-school girls aged 11 to 14 years were recruited. As girls aged, they held more permissive attitudes toward engaging in early sexual behavior and had a higher intention to engage in early sexual behavior. Intention was a significant predictor to explain sexual behavior among the girls. There is a need to develop strategies that promote intention related to delay and prevention of early sexual behavior.

    Background Nycthemeral (daily) oscillation has been documented in a variety of physiological and behavioral processes. The present study was carried out to evaluate the existence of a nycthemeral rhythm of human sexual behavior and to identify environmental factors responsible for the rhythmic pattern. Methods Non-traditional university students (ages 18 to 51 years) recorded the times of day when they went to sleep, when they woke up, and when they had sex for 3 consecutive weeks. They also answered a questionnaire designed to identify the causes of their selection of time for sex. Results The majority of sexual encounters took place at bedtime (11 pm to 1 am). The most common explanations for this temporal pattern were the rigidity of the professional work schedule and family obligations and the availability of the partner, which reduced the opportunity for sexual encounters at other times of the day. Conclusion Most sexual encounters take place around bedtime. Although the presence of an endogenous component responsible for this temporal pattern cannot be excluded, the evidence indicates strong environmental forcing, particularly from the work/family schedule of the individuals and from partner availability.

    Although research has increasingly emphasized how adolescent sexual behavior may be associated with aspects of health beyond unwanted pregnancy and sexually transmitted infections, no current theoretical or conceptual model fully explains associations between sexual behavior and multiple facets of health. We provide a conceptual model that explicates possible processes of how adolescent sexual behavior may influence physical, mental, and social health. Next, we review the current literature consistent with this conceptual model, demonstrating that although early sexual behavior can be associated with some negative outcomes, sex may be, on average, a positive experience in late adolescence. Finally, we discuss important future directions for research in these areas, including how individuals' attitudes about and perceptions of sexual behavior influence outcomes of sex.

    The last few decades have provided new perspectives on the increasingly complex interrelationships between the evolutionary epidemiology of STDs and their agents, human sexuality, and economic, social, cultural, and technological developments. Rapidly emerging HIV/AIDS, globalization, migration, and information technology are some factors that stress the importance of focusing on how old and new sexually transmitted infections (STIs) are spread, both in and between networks and populations. This review of determinants of STI transmission emphasizes their impact on disease prevalence and transmission, as well as their potential for affecting the agents themselves--directly or indirectly. Interventions aiming to control the spread of STIs and HIV on the different levels of society need to be adapted to the specific environment and need to integrate social structures, such as economic and gender inequality and mobility, as well as the great variability and complexity of sexual behavior.

    A newly developed Semantic Misattribution Procedure (SMP), a semantic variant of the Affect Misattribution Procedure (AMP), was used in three studies as an indirect measure of sexual interest. Using a known-group approach, homosexual men (Studies 1 and 2), heterosexual men (Studies 1 to 3) and heterosexual women (Study 3) were asked to guess the meaning of briefly presented Chinese ideographs as "sexual" or "not sexual". The ideographs were preceded by briefly presented primes depicting male and female individuals of varying sexual maturity. As hypothesised, the frequency of "sexual" responses increased after priming with pictures of individuals of the preferred sex and increasing sexual maturation. The SMP showed satisfactory reliability and convergent validity as indicated by correlations with direct and two indirect measures of sexual interest. In two further studies, the hypothesised pattern was replicated whereas a standard AMP with the identical prime stimuli did not produce this result. The potential usefulness of semantic variants of the AMP is discussed.

    This study examined the relations of unintentional exposure to Internet sexual content to intentions for sex and condom use and potential mediators of these relations, including attitudes, norms, and self-efficacy, among college students in China. A sample of 524 Chinese college students completed an online questionnaire. Mediation path analyses were conducted to test the theory of planned behavior as a model of the relations between unintentional exposure and intentions to have sex and use condoms. On average, students reported being unintentionally exposed to Internet sexual content about 3 to 4 times during the past month. Unintentional exposure was indirectly associated with intention to have sex, mediated through descriptive and injunctive norms. Descriptive norm was a stronger mediator for females than males. In contrast, unintentional exposure was unrelated to condom-use intention and mediators. The theory of planned behavior provides a model for the development of Internet-based interventions with these students.

    Two trials were conducted to evaluate the effect of diverse socio-sexual cues upon male sexual behavior and the reproductive performance of anestrous does (AD). Trials were conducted in northern Mexico (26°N) during the natural anestrous season (Feb-Mar) with crossbred dairy bucks. In Experiment 1, sexually inactive bucks (SIB, n=12) were randomly allotted to three groups, four males/group: a) DEE 9novelty stimulation) - daily exchange of estrogenized females (EF) 12&12h, b) NEE (no novelty stimulation) - no-exchange of EF, 24h, or c) CON (saline-treated_ -daily exchange of AF 12&12h. Sexually active bucks (SAB) from the DEE, NEE and CON groups were subsequently exposed to AD (n=72; n=24/group) and the reproductive outcomes were recorded. In Experiment 2, SAB (n=12; n=6/group) were randomly divided in: 1) B+EF - males+four-EF exposed to AF (n=36), and 2) B+NEF; males+four-saline-treated AD and exposed to AD (n=36). Prior to the onset of the experimental breeding in both experiments, the investigative (ISB), consummatory (CSB) and resting (RSB) sexual behavior of males were quantified (2h×d×2d). Sexual behaviors considered were: ISB - flehmen, ano-genital sniffing, approaches, vocalizations, kicking, penis extrusion, CSB; mount attempts and mounts, and RSB - isolation, attempted escape, aggression and distractions. While EF were an effective stimulus (P<0.05) for evoking mounting in SIB males, daily exchange of estrous does used to stimulate males promoted an enhanced response (P<0.05) in terms of both ISB and CSB. After being exposed to AD, the B+EF bucks induced an earlier estrous response (P<0.05) as compared with the B+NEF bucks. The untreated females did not induce any sexual activity in males and stimulation of ovarian function did not occur when saline treated (CON) AD were exposed to AD.

    Two trials were conducted to evaluate the effect of diverse socio-sexual cues upon male sexual behavior and the reproductive performance of anestrous does (AD). Trials were conducted in northern Mexico (26°N) during the natural anestrous season (Feb-Mar) with crossbred dairy bucks. In Experiment 1, sexually inactive bucks (SIB, n=12) were randomly allotted to three groups, four males/group: a) DEE 9novelty stimulation) - daily exchange of estrogenized females (EF) 12&12h, b) NEE (no novelty stimulation) - no-exchange of EF, 24h, or c) CON (saline-treated_ -daily exchange of AF 12&12h.

    The authors used the theory of planned behavior to examine the influence of parents and peers on early adolescent sexual attitudes, self-efficacy to limit sexual behavior, and behavioral intentions to have vaginal intercourse. Adolescents (N = 212) provided self-reports of their perception of parent and peer attitudes regarding sexual behavior. The authors used bivariate and regression analyses to examine the relation between parent and peer attitudes with adolescent sexual attitudes, self-efficacy to limit sexual behavior, and behavioral intentions to have vaginal intercourse. Although there were gender differences, the analyses revealed the importance of both parents and peers on adolescent sexual attitudes, self-efficacy to limit sexual behavior, and intentions to have vaginal sex in the next year.

  12. Sexual behavior patterns of customers of male street prostitutes.

    1992-08-01

    Information about male customers of male prostitutes, including sociodemographic and life-style characteristics, sexual and drug use behaviors, and knowledge about HIV infection were collected from a convenience sample of 211 male street prostitutes and a convenience sample of 15 male customers as part of a feasibility study. Data from these two groups indicate that despite knowledge of HIV infection and its transmission, customers engage in high-risk sexual and drug use behaviors with prostitutes. Because there is a high HIV infection rate within the male prostitute sample (175/1000) and because these customers for the most part describe themselves as bisexual or heterosexual, it is likely that male customers of male prostitutes serve as a vector of transmission of HIV infection to their other partners including the heterosexual population.

    Using propensity-matched controls, the present study examines the long-term adjustment of women reporting Childhood Sexual Trauma (CST) at or before the age of 14 in terms of parenting efficacy and parenting behavior. Data for these analyses were obtained from mother reports and from observational protocols from a longitudinal study of low-income, rural families. The novel use of propensity-matched controls to create a control group matched on family of origin variables provides evidence that, when women with CST are compared with the matched comparison women, females who experienced CST show poorer functioning across multiple domains of parenting (sensitivity, harsh intrusiveness, boundary dissolution), but not in parenting efficacy. Follow up moderation analyses suggest that the potential effects of trauma on parenting behaviors are not attenuated by protective factors such as higher income, higher education, or stable adult relationships. Implications for interventions with childhood sexual trauma histories and directions for future study are proposed. PMID:25680655

  16. Gender context of sexual violence and HIV sexual risk behaviors among married women in Iringa Region, Tanzania

    Nyamhanga, Tumaini M.; Frumence, Gasto

    2014-01-01

    Background There is a dearth of empirical research illuminating possible connections between gender imbalances and sexual violence among married women in Tanzania. There is a need to generate in-depth information on the connectivity between gender imbalances (asymmetrical resource ownership, sexual decision making, roles, and norms) and sexual violence plus associated HIV risky sexual behavior among married women. Design This paper is based on a qualitative case study that involved use of focus group discussions (FGDs). A thematic analysis approach was used in analyzing the study findings. Results The study findings are presented under the three structures of gender and power theory. On sexual division of labor, our study found that economic powerlessness exposes women to sexual violence. On sexual division of power, our study found that perception of the man as a more powerful partner in marriage is enhanced by the biased marriage arrangement and alcohol consumption. On cathexis, this study has revealed that because of societal norms and expectations regarding women's sexual behavior characterized by their sexual and emotional attachments to men, women find it hard to leave sexually abusive marriages. That is, because of societal expectations of obedience and compelled tolerance many married women do suffer in silence. They find themselves trapped in marriages that increase their risk of acquiring HIV. Conclusions This study suggests that married women experience a sexual risk of acquiring HIV that results from non-consensual sex. That non-consensual sex is a function of gender imbalances – ranging from women's economic dependence on their husbands or partners to socioculturally rooted norms and expectations regarding women's sexual behavior. The HIV risk is especially heightened because masculine sexual norms encourage men [husbands/partners] to engage in unprotected intra- and extramarital sex.

    1987-01-01

    This review examines the changes in brain composition and in various brain functions, including behavior, that can follow the ingestion of particular foods or nutrients. It details those that are best understood: the increases in serotonin, catecholamine, or acetylcholine synthesis that can occur subsequent to food-induced increases in brain levels of tryptophan, tyrosine, or choline; it also discusses the various processes that must intervene between the mouth and the synapse, so to speak, in order for a nutrient to affect neurotransmission, and it speculates as to additional brain chemicals that may ultimately be found to be affected by changes in the availability of their nutrient precursors. Because the brain chemicals best known to be nutrient dependent overlap with those thought to underlie the actions of most of the drugs used to treat psychiatric diseases, knowledge of this dependence may help the psychiatrist to understand some of the pathologic processes occurring in his/her patients, particularly those with appetitive symptoms. At the very least, such knowledge should provide the psychiatrist with objective criteria for judging when to take seriously assertions that particular foods or nutrients do indeed affect behavior (e.g., in hyperactive children). If the food can be shown to alter neurotransmitter release, it may be behaviorally-active; however, if it lacks a discernible neurochemical effect, the likelihood that it really alters behavior is small.

  18. Female homosexual behavior and inter-sexual mate competition in Japanese macaques: possible implications for sexual selection theory.

    PubMed

    2014-10-01

    In this paper, we review research related to female homosexual behavior in Japanese macaques (Macaca fuscata), including our 20-year program of research on this species. Multiple lines of evidence indicate that female homosexual behavior in this species is sexually motivated. In contrast, many sociosexual hypotheses have been tested in relation to female homosexual behavior in Japanese macaques, but none have been supported. Female Japanese macaques sometimes engage in same-sex sexual activity even when motivated opposite-sex alternatives are available. Within this context of mate choice, males compete inter-sexually for opportunities to copulate with females above and beyond any intra-sexual competition that is required. Anecdotal evidence suggests that inter-sexual competition for female sexual partners has been observed in a number of other species, including humans. At present it is unclear whether inter-sexual competition for sexual partners influences patterns of reproduction. Our understanding of sexual selection and the evolution of mating systems may be improved by investigating whether inter-sexual mate competition influences the acquisition and maintenance of reproductive partners in those species in which such interactions occur.

    Two surveys of a Northern Ireland student sample were conducted in 1987 and 1988. A total of 419 female and 201 male subjects completed self-administered anonymous questionnaires concerning their behavior, knowledge, and attitudes towards sex, AIDS, homosexuality, contraception, and relationships. Results indicated a relatively low level of sexual experience, and for those with experience, relatively few partners. The possible influences of gender and religiosity on sexual behavior and attitudes, in the context of Northern Ireland, are discussed. Subjects reported considerable variation in the amount of sex education, but the majority received little or none. This student sample held relatively conservative attitudes towards love, sex, and marriage and this was particularly true for females and for regular churchgoers. In addition, attitudes towards homosexuality were negative (particularly among regular churchgoers). Attitudes towards contraception were more positive than expected among Catholic subjects, and few indicated that they would refuse to use contraceptives on principle. Responses to items about AIDS were highly uniform, suggesting that much of the information made available to the public has been absorbed. However, the lack of uniformity of response to more general items about sex, relationships, and contraception may indicate that fundamental changes in sexual behavior are unlikely to be brought about by influencing a rather narrowly defined set of attitudes about AIDS.

    We introduce a model for the evolution of sexually transmitted diseases, in which the social behavior is incorporated as a determinant factor for the further propagation of the infection. The system may be regarded as a society of agents where in principle, anyone can sexually interact with any other one in the population, indeed, in this contribution only the homosexual case is analyzed. Different social behaviors are reflected in a distribution of sexual attitudes ranging from the more conservative to the more promiscuous. This is measured by what we call the promiscuity parameter. In terms of this parameter, we find a critical behavior for the evolution of the disease. There is a threshold below which the epidemic does not occur. We relate this critical value of promiscuity to what epidemiologists call the basic reproductive number, connecting it with the other parameters of the model, namely the infectivity and the infective period in a quantitative way. We consider the possibility of subjects to be grouped in couples.

    The study of affect in the workplace began and peaked in the 1930s, with the decades that followed up to the 1990s not being particularly fertile. Whereas job satisfaction generally continues to be loosely but not carefully thought of and measured as an affective state, critical work in the 1990s has raised serious questions about the affective status of job satisfaction in terms of its causes as well as its definition and measurement. Recent research has focused on the production of moods and emotions at work, with an emphasis, at least conceptually, on stressful events, leaders, work groups, physical settings, and rewards/punishment. Other recent research has addressed the consequences of workers' feelings, in particular, a variety of performance outcomes (e.g., helping behaviors and creativity). Even though recent interest in affect in the workplace has been intense, many theoretical and methodological opportunities and challenges remain. PMID:11752487

    Several legal cases in the United States in which adolescents were charged with child pornography distribution after sharing nude photographs of themselves with romantic partners or others have highlighted the issue of sexting behaviors among youth. Although policy makers, mental health workers, educators and parents have all expressed concern regarding the potential harm of sexting behaviors, little to no research has examined this phenomenon empirically. The current study presents some preliminary data on the incidence of sexting behavior and associated high risk sexual behaviors in a sample of 207 predominantly Hispanic young women age 16-25. Approximately 20% of young women reported engaging in sexting behavior. Sexting behaviors were not associated with most other high-risk sexual behaviors, but were slightly more common in women who found sex to be highly pleasurable or who displayed histrionic personality traits.

    Abstract Background Adolescent females who have early sexual experiences with older male partners report high rates of sexual risk behavior during adolescence, but little is known about whether these early sexual experiences are associated with adult sexual risk behavior. The purpose of this study was to investigate whether having first consensual sex with an older partner was associated with sexual risk behavior in adulthood. Methods Participants were 292 women (66% African American, mean age = 26 years) attending a public sexually transmitted disease (STD) clinic who reported having voluntary vaginal sex before age 18. Participants completed a computerized survey assessing child/adolescent sexual experiences and current adult sexual risk behavior. Results Participants were, on average, 14.6 years at first vaginal intercourse; their partners were, on average, 17.5 years. After controlling for covariates, a greater partner age difference at first intercourse was associated with more episodes of unprotected sex with a steady partner and a greater proportion of episodes of unprotected sex with a steady partner in the past 3 months. Conclusions Having an older first sex partner during adolescence was associated with sexual risk behavior in adulthood. Early sexual experiences may be important life events that influence subsequent sexual behavior. Sexual health interventions need to target female adolescents before they initiate sexual intercourse to reduce risk for STDs and human immunodeficiency virus (HIV) infection. PMID:21128817

    2014-12-01

    A relatively new theory of motivation posits that purposeful human behavior may be partly explained by multidimensional individual differences "traits of action" (motives). Its 15 motives can be characterized according to their purpose: individual integrity, competitiveness, and cooperativeness. Existing evidence supports the model on which the motives are based and the reliability and validity of strategies to assess them. This experiment tested whether the hypothetical results of consistent, motivated cooperative and competitive behavior could affect ratings of attractiveness. Male and female participants (N = 98; M age = 18.8, SD = 1.4) were shown 24 opposite-sex facial photos ranging in attractiveness. The photos were paired with one of three conditions representing theoretical outcomes that would result from low, control, and high levels of cooperative and competitive motives. As predicted, outcome descriptions representing high motive strength of six motives statistically significantly affected ratings of attractiveness. This result was independent of sex of participant and consistent with the theory. PMID:25457092

    This preliminary research provides a descriptive, systematic study of juvenile sexual homicide. Fourteen incarcerated juveniles, identified through a department of corrections computer search, were assessed using a structured diagnostic interview, an author-designed clinical interview, and a review of correctional files and other available records. Five of the offenders' victims survived the homicidal attack, but their cases were nevertheless included in this study as the offenders' intent was clearly to kill their victim, and the victim's survival was merely by chance. All victims were female and all offenders were male. Their crimes typically occurred in the afternoon, and involved a low-risk victim of the same race who lived in the offender's neighborhood. The sexual component of the crime consisted of vaginal rape in over one-half of the cases. Weapons, typically a knife or bludgeon, were used in all but one case. Thirteen of these youths had a prior history of violence, and twelve had previous arrests. Chaotic, abusive backgrounds and poor adjustment in school were typical for these boys. A conduct disorder diagnosis was present in twelve of the youths, and violent sexual fantasies were experienced by one-half of the sample. The findings in this study suggest that juvenile sexual murderers comprise less than 1% of juvenile murderers, and are likely to be an emotionally and behaviorally disturbed population with serious familial, academic, and environmental vulnerabilities.

    Sexually potent and sexually sluggish/impotent male rats were treated orally with different amounts of Turnera diffusa and Pfaffia paniculata fluid extracts (0.25, 0.50, 1.0 ml/kg). While having no effect on the copulatory behavior of sexually potent rats, both plant extracts--singly or in combination--improved the copulatory performance of sexually sluggish/impotent rats. The highest dose of either extract (1 ml/kg) (as well as the combination of 0.5 ml/kg of each extract) increased the percentage of rats achieving ejaculation and significantly reduced mount, intromission and ejaculation latencies, post-ejaculatory interval and intercopulatory interval. Neither extract affected locomotor activity. These results seem to support the folk reputation of Turnera diffusa and Pfaffia paniculata as sexual stimulants. PMID:10227074

    This study examined associations of psychological characteristics and sexual behavior with types of reasons for episodes of sexual intercourse among youth. After completing a baseline assessment, 62 adolescents (47 female) used a handheld computer to report when they had sex as soon as possible after the event as well as in response to random signals. Youth indicated for each sex event the main reason, categorized as intimacy/desire, external, affect management, and other; analyses were restricted to sex with a main partner (234 events). Baseline sexual behavior was not related to reasons for sex. Higher anxiety was associated with external reasons for sex; younger age and lower self-esteem were associated with affect management reasons. Female youth with higher impulsiveness reported more external reasons and fewer intimacy/desire reasons. Among male youth, lower self-esteem was associated with intimacy/desire reasons, but lower depression was associated with affect management reasons. These findings may aid health care providers and researchers in understanding the differences in young people's motivations for sex.

    Objectives. We examined the role of adolescent peer violence victimization (PVV) in sexual orientation disparities in cancer-related tobacco, alcohol, and sexual risk behaviors. Methods. We pooled data from the 2005 and 2007 Youth Risk Behavior Surveys. We classified youths with any same-sex sexual attraction, partners, or identity as sexual minority and the remainder as heterosexual. We had 4 indicators of tobacco and alcohol use and 4 of sexual risk and 2 PVV factors: victimization at school and carrying weapons. We stratified associations by gender and race/ethnicity. Results. PVV was related to disparities in cancer-related risk behaviors of substance use and sexual risk, with odds ratios (ORs) of 1.3 (95% confidence interval [CI] = 1.03, 1.6) to 11.3 (95% CI = 6.2, 20.8), and to being a sexual minority, with ORs of 1.4 (95% CI = 1.1, 1.9) to 5.6 (95% CI = 3.5, 8.9). PVV mediated sexual orientation disparities in substance use and sexual risk behaviors. Findings were pronounced for adolescent girls and Asian/Pacific Islanders. Conclusions. Interventions are needed to reduce PVV in schools as a way to reduce sexual orientation disparities in cancer risk across the life span. PMID:24825215

In Exp 1, ovariectomized, hormone-primed Wistar females formed three groups: G1 (1 CLS every second), G2 (1 CLS every 5s) and G3 (no CLS). Precopulatory CLS consisted of 5cycles of 1min of stimulation with the tip of a cotton swab connected to a vibrator device, followed by 1-2min of rest. CLS increased proceptive behavior in G1 compared to G2, but not compared to G3. In Exp 2, gonadally-intact rats in late proestrous received CLS prior to copulation. No differences in sexual behavior were detected between the groups, but CLS enhanced reproduction in females that received >9 intromissions. 28, 66 and 10% of females became pregnant in G1, G2, and G3, respectively. These data indicate that precopulatory CLS affects proceptive behaviors depending on the pattern and rhythm of stimulation in hormone-primed females. In virgin rats that have received sufficient vagino cervical stimulation CLS also increases fertility.

    Purpose The purpose of this study was to identify the ways in which urban Jamaican mothers influence their adolescent daughters’ sexual beliefs and behaviors in order to incorporate them into the design of a family-based human immunodeficiency virus (HIV) risk reduction intervention program. Design Focus groups were conducted with 46 14- to 18-year-old adolescent girls and 30 mothers or female guardians of adolescent girls recruited from community-based organizations in and around Kingston and St. Andrew, Jamaica. Separate focus groups were held with mothers and daughters; each included 6 to 10 participants. Focus group sessions were scripted, led by teams that included trained Jamaican and American facilitators and note-takers, and audio-taped to ensure data accuracy. Data were analyzed using qualitative content analysis. Findings Four major maternal influences were identified: mother-daughter relationship quality, mother-daughter sexual communication, monitoring or supervision, and maternal sexual role modeling. Mothers’ and daughters’ reports were consistent; both groups identified positive and negative influences within each category. Conclusions Some maternal influences were positive and health promoting; others were negative and promoted unsafe sexual activity and risk for HIV and other sexually transmitted infections. These influences were incorporated into the design of a culture-specific family-based HIV risk reduction intervention tailored to the needs of urban Jamaican adolescent girls and their mothers. Clinical Relevance In order to be effective, family-based HIV risk reduction interventions should be theory based and tailored to the target audience. The four maternal influences identified in this formative study were incorporated into the subsequent intervention design. PMID:22339731

    The field of social neuroscience has grown dramatically in recent years and certain social responses have become amenable to mechanistic investigations. Toward that end, there has been remarkable progress in determining mechanisms for a simple sexual behavior, lordosis behavior. This work has proven that specific hormone-dependent biochemical reactions in specific parts of the mammalian brain regulate a biologically important behavior. On one hand, this sex behavior depends on underlying mechanisms of CNS arousal. On the other hand, it serves as a prototypical social behavior. The same sex hormones and the genes that encode their receptors as are involved in lordosis, also affect social recognition. Here we review evidence for a micronet of genes promoting social recognition in mice and discuss their biological roles. PMID:18985112

    Twenty-four-month-old male C57BL/6 mice with low serum testosterone levels were used as a late-onset hypogonadism (LOH) animal model for examining the effects of velvet antler polypeptide (VAP) on sexual function and testosterone synthesis. These mice received VAP for 5 consecutive weeks by daily gavage at doses of 100, 200, or 300 mg kg−1 body weight per day (n = 10 mice per dose). Control animals (n = 10) received the same weight-based volume of vehicle. Sexual behavior and testosterone levels in serum and interstitial tissue of testis were measured after the last administration of VAP. Furthermore, to investigate the mechanisms of how VAP affects sexual behavior and testosterone synthesis in vivo, the expression of steroidogenic acute regulatory protein (StAR), cytochrome P450 cholesterol side-chain cleavage enzyme (P450scc), and 3β-hydroxysteroid dehydrogenase (3β-HSD) in Leydig cells was also measured by immunofluorescence staining and quantitative real-time PCR. As a result, VAP produced a significant improvement in the sexual function of these aging male mice. Serum testosterone level and intratesticular testosterone (ITT) concentration also increased in the VAP-treated groups. The expression of StAR, P450scc, and 3β-HSD was also found to be enhanced in the VAP-treated groups compared with the control group. Our results suggested that VAP was effective in improving sexual function in aging male mice. The effect of velvet antler on sexual function was due to the increased expression of several rate-limiting enzymes of testosterone synthesis (StAR, P450scc, and 3β-HSD) and the following promotion of testosterone synthesis in vivo.

    Sexually sluggish (SS) male rats represent a small proportion of animals that take a long time to ejaculate, or sometimes they do not ejaculate, when tested on repeated occasions with sexually receptive females. The current study was done in order to evaluate whether chronic estradiol (E(2)) or testosterone (T) treatment could induce consistent ejaculatory behavior in these male rats. Those males that displayed sexual behavior but did not ejaculate in at least four of five tests were classified as SS and included in the present experiment. They were implanted subcutaneously with Silastic capsules that were empty or filled with E(2) or T. Starting one week after the implant, subjects were tested weekly with sexually receptive females for seven consecutive weeks. At the end of the experiment all subjects were weighed and sacrificed to weigh the accessory sex glands. The results showed that SS males implanted with an empty or T-filled capsule remained as such; they displayed mounts and intromissions but not a consistent pattern of ejaculation despite the twelve weeks of testing (5 screening tests and 7 with the corresponding implant). In contrast, the percentage of SS males implanted with an E(2) capsule that displayed the ejaculatory pattern was significantly reduced. Subjects treated with E(2) also displayed a higher number of mounts than the empty capsule group during several weeks of testing. At the end of the experiment the weights of the body, testicles, epididymis, seminal vesicles, and prostate of the SS male rats chronically treated with E(2) were lower than those of the empty or T capsule groups. In addition, male rats with a T implant showed lower testicular weight than the empty capsule group. These results suggest that the lack of ejaculation patter in SS male rats is not due to estrogenic or androgenic alteration.

    This study examined sexual risk behaviors and sexual refusal assertiveness in relationship to child sexual abuse (CSA), emotion dysregulation, and adult sexual revictimization. Path analyses of 1,094 survivors who had sex in the past year were done to examine sexual risk behavior, and sexual refusal assertiveness mediational pathways by which CSA severity and emotion dysregulation may affect revictimization over one year in adult female sexual assault survivors. Exchanging sex for money and sexual refusal assertiveness were significantly associated with emotion dysregulation, whereas exchanging sex for money, and not sexual refusal assertiveness, was only significantly related to CSA severity. Both exchanging sex for money and sex refusal assertiveness mediated the relationship between emotion dysregulation and adult sexual revictimization. Exchanging sex for money mediated the CSA severity-revictimization relationship. These findings demonstrate the importance of considering both risky and protective sexual behaviors in research and prevention programming that address sexual revictimization in women. PMID:25942287

    Background: This study was conducted to identify the determinants of protective behavior in relation to HIV transmission. Since the risk of transmission is higher among those who have extramarital intercourse, the study sample constituted of such people. Methods: We started this study in 2010 and finished it in 2011. Participants were divided into low-risk and high-risk groups. High-risk people included sex workers and those who presented at drop-in centers. Interviewees were 18 men and women in the low-risk group and 12 men and women in the high-risk group. Data were collected through in-depth interviews and were analyzed using the thematic framework method. Results: In both groups, protective behavior was influenced by willingness to protect, intention or decision to protect, and personal, social, and environmental barriers and facilitators. In terms of willingness, behavior was influenced to preserve sexual pleasure by avoiding condoms. In terms of barriers and facilitators, trust in partner, misperceptions, condom inaccessibility, unplanned sex, fear of contracting the disease, partner’s wish, ethical commitments were mentioned by both groups, stigma of condom possession by the low-risk group, and partner’s force was mentioned by the high-risk group. Conclusion: Educational programs need to focus on changing the concept that “condoms reduce sexual pleasure”. In addition, interventional programs to strengthen factors such as self-efficacy, ethical commitments, faithfulness, and correct beliefs such as undue trust in partner, misconception of being safe, unplanned sex, and the stigma of possessing condoms can be very effective in changing high-risk sexual behavior.

  9. The relation between sexual behavior and religiosity subtypes: a test of the secularization hypothesis.

    Previous literature on religion and sexual behavior has focused on narrow definitions of religiosity, including religious affiliation, religious participation, or forms of religiousness (e.g., intrinsic religiosity). Trends toward more permissive premarital sexual activity in the North American Christian-Judeo religion support the secularization hypothesis of religion, which posits an increasing gap between religious doctrine and behavior. However, the recent rise of fundamentalist and new age religious movements calls for a reexamination of the current link between religion and sexual behavior. The use of dual definitions of religiosity, including religious affiliation and dimensional subtypes, may further characterize this link. The present cross-sectional study evaluated patterns of sexual behavior in a young adult sample (N = 1302, M age = 18.77 years) in the context of the secularization hypothesis using religious affiliation and a liberal-conservative continuum of religious subtypes: paranormal belief, spirituality, intrinsic religiosity, and fundamentalism. Results indicated few affiliation differences in sexual behavior in men or women. Sexual behaviors were statistically predicted by spirituality, fundamentalism, and paranormal belief, and the endorsement of fundamentalism in particular was correlated with lower levels of female sexual behavior. The secularization hypothesis was supported by consistent levels of sexual activity across affiliations and is contradicted by the differential impact of religiosity subtypes on sexual behavior. Findings suggested that the use of religious subtypes to evaluate religious differences, rather than solely affiliation, may yield useful insights into the link between religion and sexual behavior.

    Although there is continuing debate about whether sexual selection promotes or impedes adaptation to novel environments, the role of mating behavior in such adaptation remains largely unexplored. We investigated the evolution of mating behavior (latency to mating, mating probability and duration) in replicate populations of seed beetles Callosobruchus maculatus subjected to selection on life-history ("Young" vs. "Old" reproduction) under contrasting regimes of sexual selection ("Monogamy" vs. "Polygamy"). Life-history selection is predicted to favor delayed mating in "Old" females, but sexual conflict under polygamy can potentially retard adaptive life-history evolution. We found that life-history selection yielded the predicted changes in mating behavior, but sexual selection regime had no net effect. In within-line crosses, populations selected for late reproduction showed equally reduced early-life mating probability regardless of mating system. In between-line crosses, however, the effect of life-history selection on early-life mating probability was stronger in polygamous lines than in monogamous ones. Thus, although mating system influenced male-female coevolution, removal of sexual selection did not affect the adaptive evolution of mating behavior. Importantly, our study shows that the interaction between sexual selection and life-history selection can result in either increased or decreased reproductive divergence depending on the ecological context.

    Male sexual behavior (MSB) in rodents, in both its consummatory and motivational components, is regulated by hormones such as testosterone, 17β-estradiol and 5-α-dihydrotestosterone. In experiments, neonatal treatment with clomipramine (CMI; a serotonin reuptake inhibitor) reproduces some of the signs of depression in adult age, including reduced sexual behavior manifested in a lower percentage of subjects that mount, intromit and ejaculate, although their testosterone levels were not altered. However, the effect of this treatment on estrogen levels and the consequences of hormone substitution using 17β-estradiol and 5-α-dihydrotestosterone on the expression of male sexual behavior are still unknown. Therefore, the objective of the present study was to analyze the effect of neonatal treatment with CMI on plasma testosterone and 17β-estradiol levels, and the role of testosterone, 17β-estradiol and 5-α-dihydrotestosterone in altering the consummatory and motivational components of sexual behavior in male rats. To this end, it analyzed the copulatory parameters and sexual incentive motivation (SIM) of rats treated with CMI under two conditions: basal and post-hormone replacements. Neonatal treatment with CMI did not affect plasma testosterone or 17β-estradiol concentrations, but did decrease both the consummatory component and sexual motivation according to the results of the SIM test. These aspects were recovered after administering 17β-estradiol +5-α-dihydrotestosterone, but not testosterone.

    Gang youth are at an increased likelihood of participating in unsafe sexual behaviors and at an elevated risk of exposure to sexually transmitted infection (STIs), including HIV. This manuscript presents quantitative and qualitative data on sexual behaviors among a sample of predominately heterosexual, male gang youth aged 16 to 25 years interviewed in Los Angeles between 2006 and 2007 (n = 60). In particular, sexual identity, initiation and frequency of sex, and number of sexual partners; use of condoms, children, and other pregnancies; group sex; and STIs and sex with drug users. We argue that gang youth are a particular public health concern, due to their heightened risky sexual activity, and that behavioral interventions targeting gang youth need to include a component on reducing sexual risks and promoting safe sexual health.

    There is increasing evidence that exposure to stressors in adolescence has long-lasting effects on emotional and cognitive behavior, but little is known as to whether reproductive functions are affected. We investigated appetitive and consummatory aspects of sexual behavior in male rats that were exposed to chronic social instability stress (SS, n=24) for 16 days in mid-adolescence compared to control rats (CTL, n=24). Over five sexual behavior test sessions with a receptive female, SS rats made fewer ejaculations (p=0.02) and had longer latencies to ejaculation (p=0.03). When only data from rats that ejaculated in the fifth session were analyzed, SS rats (n=18) had reduced copulatory efficiency (more mounts and intromissions before ejaculation) compared to CTL rats (n=19) (p=0.004), and CTL rats were twice as likely as SS rats to make more than one ejaculation in the fifth session (p=0.05). Further, more CTL (14/24) than SS (5/25) rats ejaculated in four or more sessions (p=0.05). SS rats had lower plasma testosterone concentrations than CTL rats (p=0.05), but did not differ in androgen receptor, estrogen receptor alpha, or Fos immunoreactive cell counts in the medial preoptic area. The groups did not differ in a partner preference test administered between the fourth and fifth sexual behavior session. The results suggest that developmental history contributes to individual differences in reproductive behavior, and that stress exposures in adolescence may be a factor in sexual sluggishness.

    Using psychiatric interviews, sexual and affect rating scales, hormonal studies, and neurologic assessment, the authors assessed the effect of L-dopa treatment on men with Parkinson's disease. Patients demonstrated variable affect changes. Approximately one-half of the patients reported an increased sexual interest that was not related to improvement in locomotor function. Hormonal factors appeared to be involved. The findings suggest that male parkinsonian patients who possess an intact hypothalamic-pituitary-gonadal axis experience increased sexual function related to L-dopa treatment.

    The current study examined how impulsivity-related traits (negative urgency, sensation seeking, and positive urgency), behavioral measures of risk taking and reward seeking, and physiological reactivity related to three different risky sexual behaviors in sexually active undergraduate men (N = 135). Regression analyses indicated that sensation seeking and behavioral risk-taking predicted unique variance in number of sexual partners. These findings suggest that, for young men, acquisition of new partners is associated with need for excitement and reward and willingness to take risks to meet those needs. Sensation seeking, behavioral risk-taking, and skin conductance reactivity to arousing stimuli was related to ever having engaged in sex with a stranger, indicating that, for men, willingness to have sex with a stranger is related not only to the need for excitement and risk-taking but also with innate responsiveness to arousing environmental triggers. In contrast, regression analyses indicated that young men who were impulsive in the context of negative emotions were less likely to use condoms, suggesting that emotion-based impulsivity may be an important factor in negligent prophylactic use. This study adds to the current understanding of the divergence between the correlates of risky sexual behaviors and may lend utility to the development of individualized HIV prevention programming.

    Women represent almost half of the people living with HIV worldwide. Although social discrimination has been recognized as a major obstacle to HIV prevention, few empirical studies have examined the effects of sexism on women's HIV sexual risk behaviors. We analyzed data collected from an ethnically diverse sample of 754 women attending family planning clinics in the San Francisco Bay Area. A majority of respondents reported lifetime experiences of sexism (e.g., 94% reported sexual harassment). Structural equation modeling results demonstrated that experiences of sexism and reports of recent unprotected sex with a primary or a secondary sexual partner were linked through psychological distress and difficult sexual situations. Our results suggest the need to develop HIV prevention strategies for women that address two mechanisms-psychological distress and difficult sexual situations-that link social discrimination to women's sexual risk for HIV.

    This study examined the influence of demographic characteristics, sexual identity, hazardous drinking, and sexuality/intimacy enhancement alcohol expectancies on rates of risky sexual behaviors in a community sample of women who self-identified as lesbian, mostly lesbian and bisexual (N = 349). Structured interview data were collected as part of a larger longitudinal study of sexual minority women’s health, the Chicago Health and Life Experiences of Women study. We used structural equation modeling, controlling for demographic characteristics, to evaluate the influence of sexual identity, hazardous drinking, and alcohol-related sexuality/intimacy enhancement expectancies on sexual risk behaviors. Controlling for demographic characteristics and for sexual identity, higher levels of both hazardous drinking and sexuality/intimacy enhancement alcohol expectancies were associated with higher sexual risk scores. The final model predicted 36% of the variance in risky sexual behavior scores. Our findings regarding the central role of alcohol use and sexuality/intimacy enhancement expectancies in sexual risk behaviors among sexual minority women (SMW) are consistent with previous research focusing on predominantly heterosexual women. Future efforts at sexual risk reduction in SMW will need to address the influences of alcohol use and drinking-related expectancies on sexual behaviors and decision-making. PMID:24071822

    Galanin-like peptide (GALP) is a recently described neuropeptide, which shares a partial sequence identity with galanin but is derived from a separate gene. Central injections of GALP stimulate the secretion of gonadotropin-releasing hormone (GnRH) and luteinizing hormone (LH) and induce the expression of Fos in several brain areas known to regulate male sexual behavior in the rat. We postulated that GALP may also stimulate sexual behavior in concert with its stimulatory effect on the hypothalamic-pituitary-gonadal (HPG) axis. To test this hypothesis, we administered GALP, galanin, or the vehicle (artificial cerebrospinal fluid, aCSF) alone to sexually experienced male rats and assessed the effects of these agents on sexual behavior. We observed that compared to aCSF alone, GALP significantly increased all aspects of male-typical sexual behavior, whereas galanin inhibited all of these same behaviors. To examine whether the stimulatory effects of GALP on sexual behavior were mediated by GALP's stimulatory effects on the HPG axis, we castrated the same male rats and repeated the behavioral experiment. We found that GALP maintained its inductive action on male-typical sexual behaviors in the castrated animals, suggesting that the effects of GALP on sexual behavior are not the result of GALP's ability to stimulate testosterone secretion. These observations suggest that GALP neurons are part of the hypothalamic circuitry controlling sexual behavior in the male rat.

    In the Japanese quail, 7α-hydroxypregnenolone, a previously undescribed avian neurosteroid, is actively produced in the brain. 7α-Hydroxypregnenolone acts as a novel neuronal activator to stimulate locomotor activity of quail. Therefore, in this study, we determined whether 7α-hydroxypregnenolone changes the expression of sexual behavior in Japanese quail. We first measured diurnal changes in sexual behavior of male quail exposed to a long-day photoperiod. We found that sexual behavior of male quail was high in the morning when endogenous 7α-hydroxypregnenolone level is high. Subsequently, we centrally administered 7α-hydroxypregnenolone in the evening when endogenous 7α-hydroxypregnenolone level is low. In the 30 min after intracerebroventricular (ICV) injection, 7α-hydroxypregnenolone dose dependently increased the frequency of sexual behavior of male quail. However, 7β-hydroxypregnenolone, a stereoisomer of 7α-hydroxypregnenolone, did not effect on the frequency of sexual behavior of male quail. In addition, to confirm the action of 7α-hydroxypregnenolone on sexual behavior, male birds received an ICV injection of ketoconazole, an inhibitor of cytochrome P450s, and behavioral experiments were performed in the morning. Ketoconazole significantly decreased the frequency of sexual behavior of male quail, whereas administration of 7α-hydroxypregnenolone to ketoconazole-treated males increased the frequency of their sexual behavior. These results indicate that 7α-hydroxypregnenolone regulates diurnal changes in sexual behavior of male quail.

    Research on the role of sex-related Internet use in adolescents’ sexual development has often isolated the Internet and online behaviors from other, offline influencing factors in adolescents’ lives, such as processes in the peer domain. The aim of this study was to test an integrative model explaining how receptive (i.e., use of sexually explicit Internet material [SEIM]) and interactive (i.e., use of social networking sites [SNS]) sex-related online behaviors interrelate with perceived peer norms in predicting adolescents’ experience with sexual behavior. Structural equation modeling on longitudinal data from 1,132 Dutch adolescents (Mage T1 = 13.95; range 11-17; 52.7% boys) demonstrated concurrent, direct, and indirect effects between sex-related online behaviors, perceived peer norms, and experience with sexual behavior. SEIM use (among boys) and SNS use (among boys and girls) predicted increases in adolescents’ perceptions of peer approval of sexual behavior and/or in their estimates of the numbers of sexually active peers. These perceptions, in turn, predicted increases in adolescents’ level of experience with sexual behavior at the end of the study. Boys’ SNS use also directly predicted increased levels of experience with sexual behavior. These findings highlight the need for multisystemic research and intervention development to promote adolescents’ sexual health. PMID:26086606

  3. Identifying peer effects using spatial analysis: the role of peers on risky sexual behavior

    2014-01-01

    This paper explores the role of peer effects on early sexual debut for a sample of adolescents using data from the National Longitudinal Study on Adolescent Health (Add Health). Most studies analyzing peer influences ignore the “reflection” problem that occurs with studying peer effects. To address the reflection problem, this paper employs a spatial econometric approach to estimate a social interactions model. This is the first study in the literature on adolescent risky sexual behavior to use this approach to estimate peer effects. Similar to other research on peer effects and adolescent risky sexual behavior, this paper finds the existence of peer effects. However, the more vital outcome from this study is that older and male peers increase the likelihood of adolescent early sexual debut, while peers whose mothers are more open about sexual activity decrease adolescent risky sexual behavior. This methodology can help further our knowledge about the social context that influences adolescent sexual behavior. PMID:26300714

    Reviewed in this chapter are: (1) correlations among human sexual behavior, brain pathology, and brain activity, including caveats regarding the interpretation of "cause and effect" among these factors, and the degree to which "hypersexuality" and reported changes in sexual orientation correlated with brain pathology are uniquely sexual or are attributable to a generalized disinhibition of brain function; (2) the effects, in some cases inhibitory, in others facilitatory, on sexual behavior and motivation, of stroke, epileptic seizures, traumatic brain injury, and brain surgery; and (3) insights into sexual motivation and behavior recently gained from functional brain imaging research and its interpretive limitations. We conclude from the reviewed research that the neural orchestra underlying the symphony of human sexuality comprises, rather than brain "centers," multiple integrated brain systems, and that there are more questions than answers in our understanding of the control of human sexual behavior by the brain - a level of understanding that is still in embryonic form.

    Multiple mating by females is widely thought to encourage post-mating sexual selection and enhance female fitness. We show that whether polyandrous mating has these effects depends on two conditions. Condition 1 is the pattern of sperm utilization by females; specifically, whether, among females, male mating number, m (i.e. the number of times a male mates with one or more females) covaries with male offspring number, o. Polyandrous mating enhances sexual selection only when males who are successful at multiple mating also sire most or all of each of their mates' offspring, i.e. only when Cov♂(m,o), is positive. Condition 2 is the pattern of female reproductive life-history; specifically, whether female mating number, m, covaries with female offspring number, o. Only semelparity does not erode sexual selection, whereas iteroparity (i.e. when Cov♀(m,o), is positive) always increases the variance in offspring numbers among females, which always decreases the intensity of sexual selection on males. To document the covariance between mating number and offspring number for each sex, it is necessary to assign progeny to all parents, as well as identify mating and non-mating individuals. To document significant fitness gains by females through iteroparity, it is necessary to determine the relative magnitudes of male as well as female contributions to the total variance in relative fitness. We show how such data can be collected, how often they are collected, and we explain the circumstances in which selection favouring multiple mating by females can be strong or weak. PMID:23339237

    Males horses castrated prepubertally occasionally display stallion-like sexual and aggressive behavior as adults. A retrospective survey of 140 horse owners was undertaken to compare the effectiveness of prepubertal versus postpubertal castration on objectionable sexual and aggressive behavior. Of 94 geldings that had been castrated prepubertally (before 2 years of age), 20% to 30% displayed stallion-like sexual behavior and aggression toward horses, and 5% were aggressive toward people in a stallion-like manner. This occurrence of problem behavior was not significantly different from the occurrence of these behavioral patterns in 46 geldings that had been castrated as stallions (over 3 years of age). When castration was examined as a therapeutic measure to eliminate sexual and aggressive behavior in stallions in which the behavior had become objectionable, it was found that the operation was effective on sexual behavior and aggression toward people in 60% to 70% of horses and on aggression toward horses in 40% of horses.

    CONTEXT: Effects of zinc on male sexual competence are poorly understood. AIM: To study the effects of different doses of zinc on the sexual competence of males using a rat model. MATERIALS AND METHODS: Three subsets (eight in each subset) of sexually experienced adult male rats were supplemented with three different oral doses of zinc sulphate (a daily dose of 1 mg, 5 mg and 10 mg respectively) for two weeks. A subset of eight animals without zinc supplementation was used as the control group Sexual behavior was observed by placing them individually in cages with receptive females. STATISTICAL ANALYSIS: Data analysis was done using SPSS v10 for windows computer software. RESULTS: Supplementation of 5 mg of zinc/day for two weeks led to a prolongation of ejaculatory latency; 711.6 sec. (SEM 85.47) vs. 489.50 sec. (SEM 67.66), P < 0.05 and an increase in number of penile thrusting; 52.80 (SEM 11.28) vs. 26.50 (SEM 6.17), P < 0.05, compared to controls. The same group had elevated prolactin (PRL) and testosterone (T) levels compared to controls at the end of treatment period; PRL- 7.22 ng/dl (SEM 3.68) vs. 2.90 ng/dl (SEM 0.34) and T- 8.21 ng/ml (SEM 6.09) vs. 2.39 ng/ml (SEM 1.79), P < 0.05. In contrast, reduction of libido was evident in the same group, but this effect was not statistically significant (P > 0.05). However, partner preference index was positive and 5 mg zinc supplementation did not exert a significant adverse effect on the muscle strength and co-ordination. The subset of rats supplemented with 1 mg/day did not show a difference from the control group while supplementation with 10 mg/day led to a reduction of the libido index, number of mounts and intromissions. CONCLUSIONS: Zinc therapy improves sexual competence of male rats; the effect is dose dependent. Increase in the T levels is beneficial in this regard. However, increase in PRL is responsible for the reduced libido index. Further studies on pigs and monkeys are needed to evaluate the

    This paper brings together contemporary thinking about early attachment and affect regulation with our clinical and theoretical understanding of the problems of adult sexuality. In addition to recent theories of affect regulation and attachment, we incorporate Laplanche's idea of 'excess', which was an important transitional concept integrating real experience with fantasy in sexuality. We elaborate the idea of excess-- 'too-muchness' --to illuminate the early overwhelming of the psyche that affects the formation of sexuality. Linked to recent theoretical developments, this idea helps to grasp the relationship between sexual excitement and early affect regulation, showing how excitement becomes dangerous, thus impeding or distorting desire. The 'too-muchness' of excitement recalls the experience of being a stimulated, overwhelmed, unsoothed child and influences later inability to tolerate sexual arousal and the excitement affect. A clinical case illustrates this connection between attachment trauma, anxiety about sexuality, as well as shameful experiences of gender identity as an area of trauma. We emphasize the importance of working through the terrors and desires of the mother-baby relationship as they emerge in the transference-countertransference in order to develop the ability to hold excitement and stimulation without experiencing the too-much as the intolerable. This includes the working-through of ruptures related to overstimulation as well as the delicate balance of attention to fantasy and intersubjective work in the transference. PMID:25704459

    Parents have the potential to protect against adolescent sexual risk, including early sexual behavior, inconsistent condom use, and outcomes such as pregnancy and sexually transmitted infections (STIs). Identification of the specific parenting dimensions associated with sexual risk in adolescence and young adulthood is necessary to inform and focus prevention efforts. The current study examined the relation of proximal (e.g., discussions of sexual costs) and distal (e.g., parental involvement, relationship quality) parenting variables with concurrent and longitudinal adolescent sexual behavior. The National Longitudinal Study of Adolescent Health (Add Health) provided a nationally representative sample with information about the family using adolescent and parent informants. Longitudinal information about sexual risk included adolescent condom use and adolescent sexual initiation, as well as young adult unintended pregnancy, reports of STIs, and biological assay results for three STIs. Higher parent-adolescent relationship quality was associated with lower levels of adolescent unprotected intercourse and intercourse initiation. Better relationship quality was also associated with lower levels of young adult STIs, even when accounting for prior sexual activity. Unexpectedly, more parent reports of communication regarding the risks associated with sexual activity were negatively associated with condom use and greater likelihood of sexual initiation. These results demonstrate that parents play an important role, both positive and negative, in sexual behavior, which extends to young adulthood, and underscores the value of family interventions in sexual risk prevention.

    Little is known about the relationship between personality and sexual development among mid-adolescents. In the current study, we used a person-centered approach to investigate the relation between personality types and the development of sexual behavior. We hypothesized that undercontrolling adolescents would engage in more advanced, casual, and risky sexual behavior compared to their resilient and overcontrolling peers. Data were used from 407 mid-adolescents (Mage = 14.5) followed across four measurement waves spanning 18 months. Results from latent class analyses (LCA) identified the three classical personality types: resilients, undercontrollers, and overcontrollers. Controlling for perceived pubertal timing and biological sex, latent growth curve analyses in Mplus showed that, at baseline, undercontrollers were more sexually experienced and engaged in more casual and risky sexual behavior than resilients and overcontrollers. Although initial levels of sexual behavior differed by personality types, over time increases in sexual behavior occurred at a similar rate across the types. Overall, the current study showed that undercontrolling adolescents are early sexual developers who engage in more advanced, casual, and risky sexual behavior than other adolescents. The implications of these findings for longer-term differences in sexual behavior between personality types in later adolescence are discussed.

    Alcohol consumption is associated with sexual behavior and outcomes, though research indicates a variety of moderating factors, including demographic characteristics. To better target interventions aimed at alcohol-related sexual risk behavior, our analyses simultaneously examine demographic predictors of both day- and event-level associations between alcohol consumption and sexual behavior in a sample of young adults (N = 301) who are sexually active and consume alcohol. Young adults (aged 18-29) recruited using time-space sampling and incentivized snowball sampling completed a survey and a timeline follow-back calendar reporting alcohol consumption and sexual behavior in the past 30 days. On a given day, a greater number of drinks consumed was associated with higher likelihood of sex occurring, particularly for women and single participants. During a given sexual event, number of drinks consumed was not associated with condom use, nor did any demographic predictors predict that association. Findings highlight associations between alcohol and sexual behavior, though not between alcohol and sexual risk behavior, highlighting the need for additional research exploring the complex role of alcohol in sexual risk behavior and the need to develop prevention efforts to minimize the role of alcohol in the initiation of sexual encounters.

    The relationship between sex steroids and sexual behavior was examined in 19 oral contraceptive users. Retrospective assessment of sexual attitudes were obtained and women completed daily ratings of sexual behavior and well-being for 28 days. Plasma levels of free testosterone (T), estradiol, and progesterone were measured at weekly intervals. In addition, women performed a novel selective attention task designed to measure the strength of the tendency to be distracted by sexual stimuli. Multiple regression analyses using average sexual behavior variables as dependent variables, and hormone levels sexual attitudes and well-being as predictor variables, showed that free T was strongly and positively associated with sexual desire, sexual thoughts, and anticipation of sexual activity. A role for T in attention to sexual stimuli was also supported by the positive correlation between free T and the bias for sexual stimuli in a subgroup of women. These results are consistent with the hypothesis that T may enhance cognitive aspects of women's sexual behavior. PMID:8493300

    2015-09-01

    Much of the social behavior in which rodents engage is related to reproduction, such as maintaining a breeding territory, seeking mates, mating, and caring for their young. Rodents belong to the internally fertilizing species that require sexual behavior for reproduction. The dyadic, heterosexual patterns of most mammalian species are sexually dimorphic, but they also share mutual components in both sexes: sexual attraction is reciprocal, sexual initiative is assumed, appetitive behavior is engaged in, and mating involves consummatory and postconsummatory phases in females as well as in males. Serotonin, a phylogenetically ancient molecule, is the most widely distributed neurotransmitter in the brain and its signaling pathways are essential for numerous functions including sexual behavior. Since the late 1960s, brain serotonergic neurotransmission has been considered to exert an inhibitory influence on the neural mechanisms mediating sexual behavior. This contention was based mainly on the observations that a decrease in central serotonergic activity facilitated the elicitation of sexual behavior, whereas an increase in central serotonergic activity attenuated it. However, the discovery of over 14 types of serotonin receptors has added numerous layers of complexity to the study of serotonin and sexual behavior. Evidence shows that, upon activation, certain receptor subtypes facilitate, whereas some others suppress, sexual behavior, as well as sexual arousal and motivation. Furthermore, the role of these receptors has been shown to be different in the male and female sexes. The use of serotonergic pharmacological interventions, mouse strains with genetic polymorphisms causing alterations in the levels of brain serotonin, and animal models with genetic manipulations of various serotonin effectors has helped delineate the fundamental role of this neurotransmitter in the regulation of sexual behavior.

    Disruption of the sexual differentiation process during critical periods in male rodents produces changes in partner preference and sexual behavior. In this study we used prenatal (gestation days 10-22) letrozole (0.31 and 0.56 μg/kg) to inhibit aromatase and alter normal sexual differentiation of males. These animals and control rats (injected with vehicle) were used when adults to study: a) sexual preference (where the experimental male could choose to interact with a receptive female or a sexually experienced male); b) masculine and feminine sexual behaviors (tested in cylindrical arenas); c) non-contact erections when exposed to a female or a male and, d) serum sex steroids and gonadotropin levels. The results showed that 30% of the males treated with letrozole (0.56 μg/kg) had same-sex preference, 33% displayed lordosis and 63% showed non-contact erections in the presence of a sexually experienced male. However, 44% of these males also exhibited complete masculine sexual behavior towards receptive females. None of the control males displayed lordosis when mounted by another male and very few (12%) showed non-contact erections when exposed to a sexually experienced male. Similar low percentages were found in those males prenatally treated with the low letrozole dose (0.31 μg/kg). No difference was found in the serum levels of testosterone, estradiol, LH and FSH between control and letrozole-treated males regardless of their sexual preference. These results indicate that prenatal selective inhibition of aromatization produces feminization of sexual partner preference, arousal and sexual behavior but does not affect masculine sexual behavior.

    2006-01-01

    Since adolescents are now engaging in sexual activity in their early years, sexual behavior needs to be explored to prevent contact with HPVs and other sexually transmitted diseases (STD), including cervical cancer. This qualitative study aimed to explore this question from adolescents' view points in their natural context. The participants were 19 individuals aged 13-19 years living in rural families in Khon Kaen province, Thailand. The preliminary findings indicated that factors contributing to low sexual risk behavior were helping family to do housework, an emphasis on learning, listening to parents, and following their advice. Adolescent behavior leading to high sexual risk included being very close to friends, having a wide social circle, going out for enjoyment at night time, returning home late at night, drinking alcohol, smoking, paying less attention to learning, not listening to parents, and not following their advice. Adolescent sexual behavior was found to comprise: 1) sexual activities themselves; 2) non-disclosure of having sex; and 3) protective behavior. Sexual activities were ranked from low risk to high risk of sexual health. Low risk included having a steady boy/girlfriend, hugging, and kissing. High risk sexual behavior featured unprotected sex, abuse or rape, and abortion. Important influences were: eagerness to learn and try to have sex, mens' sexual desire, peer group value of having sex, and material value. The adolescents demonstrated no willingness to disclose having a boy/girl friend, having sex and negative consequences like becoming pregnant. Sexual protective behavior was up to males, whether they were willing to use a condom, with females having little power to negotiate. The study suggests that inappropriate adolescent risk behavior and social values need to be a focus of attention for education. In particular, families need to take action by early detection of adolescent sexual risk behavior. PMID:17250438

    Adolescents have high rates of sexually transmitted infections (STIs). Adolescents consuming alcohol and using drugs have markedly greater HIV/STI risk and are a priority population for intervention. Accurate measurement of sexual risk behavior is critical for understanding individual's risk for HIV/STI, transmission dynamics of HIV/STI, and evaluating the efficacy of interventions designed reduce HIV/STI risk. However, significant challenges to accurately measuring adolescents' self-reported sexual behavior are well-documented. Recent advances in microbiology, such as the use of less invasive specimen collection for DNA assays, can assist researchers in more accurately measuring adolescents' sexual risk behavior. However, the majority of studies of adolescents' sexual risk rely solely on self-reported behavior; therefore, methods to improve the validity of adolescents' self-reported sexual behavior are needed. In addition, integrating biologic measures to complement self-reported measures are recommended, when appropriate and feasible.

    Theory-based sexual risk reduction interventions are often demonstrated effective, but few studies have examined the mechanisms that mediate their behavior changes. In addition, critical contextual factors, such as alcohol use, are often not accounted for by social cognitive theories and may add to the explanatory value of intervention effects. The purpose of this study is to examine the underlying mechanisms driving condom use following a brief sexual risk reduction intervention grounded in the information, motivation, behavioral skills (IMB) model of behavior change. We examined IMB theoretical constructs and alcohol-related contextual factors as potential mediators in separate models. Patients (n = 617) from an STI clinic in Cape Town, South Africa were randomly assigned to either a brief risk reduction intervention or an education-only control condition. We assessed IMB, and alcohol-related variables at baseline, 3, 6, 9, and 12 months and modeled IMB constructs and alcohol-related factors as mediators of behavior change. Results of growth-curve mediational modeling showed that 1 year after counseling, the intervention indirectly affected sexual risk behavior through alcohol-related constructs, but not IMB constructs. Alcohol use and related factors play critical roles in explaining HIV and STI risk reduction intervention effects. Interventions that directly address alcohol use as a factor in sexual risk behavior and behavior change should be the focus of future research.

    Little is known about the association between self-reported academic performance and risky sexual behaviors and if this differs by gender, among university students. Academic performance can create psychological pressure in young students. Poor academic performance might thus potentially contribute to risky sexual behavior among university students. The aim of this study was to investigate the association between self-reported academic performance and risky sexual behaviors, and whether gender affects this relationship among Ugandan university students. In 2010, 1,954 students participated in a cross-sectional survey, conducted at Mbarara University of Science and Technology in southwestern Uganda (72% response rate). Multivariate logistic regression analysis was used for the analysis. 1,179 (60.3%) students in our study sample reported having debuted sexually. Of these 440 (42.2%) used condoms inconsistently with new sexual partners, and 344 (33.6%) had had multiple sexual partners. We found a statistically significant association between poor academic performance and inconsistent condom use with a new sex partner and this association remained significant even after adjusting for all the potential confounders. There was no such association detected regarding multiple sexual partners. We also found that gender modified the effect of poor academic performance on inconsistent condom use. Females, who were poor academic performers, were found to be at a higher risk of inconsistent condom use than their male counterparts. Interventions should be designed to provide extra support to poor academic performers, which may improve their performance and self-esteem, which in turn might reduce their risky sexual behaviors.

  13. Changes in Thai sexual behavior lower HIV spread.

    More than 700,000 people are thought to be HIV positive in Thailand. A booming sex industry and social attitudes which support the male patronage of prostitutes are major factors in the spread of disease in the country. A 4-day workshop on sexual behavior and AIDS in Thailand was attended by representatives from Burma, Cambodia, China, Indonesia, Malaysia, the Philippines, Thailand, and Vietnam. According to the Joint UN Program on HIV/AIDS (UNAIDS), the percentage of military conscripts in northern Thailand who visited a brothel in the past year fell from 58% in 1991 to 23% in 1995, while the percentage of recruits using condoms during their most recent brothel visits increased from 60% to 90% over the same period. Statistics from the Thai Public Health Ministry indicate that the percentage of men in the general population who used condoms when visiting a brothel increased from 40% in 1990 to 90% in 1994. Furthermore, a nationwide survey among military conscripts found the prevalence of HIV infection fell from 3.7% in 1993 to 2.5% in 1995, with the downward trend continuing in 1996. This success in reducing the level of sexual risk behavior and the incidence of HIV infection in Thailand lends hope for the possibility of changing the course of the HIV/AIDS epidemic elsewhere.

    There is little data on female-to-female transmission of HIV. Some women who have sex with women (WSW) have other high-risk behaviors that could lead to HIV infection. The belief that WSW are at no risk may lead to unsafe sexual practices. In this study, a convenience sample of 78 women was surveyed in order to explore the perception of HIV risk among lesbians, their sexual behaviors, and their sources of information about safer sex. Fifty-three percent reported they were at low risk for contracting HIV. Women reported knowledge of barrier methods (89% to 99%) and no sex during menstruation (92%). However, 35% to 40% reported no knowledge of less common safer sex practices. Women reported their source of knowledge as media (36%), workshops (22%), and friends (12%). Eighty-five percent stated that their health care provider knew they were lesbian, but only 15% reported receiving safer sex education. Nurses and nurse practitioners are aptly poised to provide critical HIV education and health care for this population.

    The empirical literature on sexual homicide has posited the sexual murderer as a unique type of offender who is qualitatively different from other types of offenders. However, recent research has suggested that sexual homicide is a dynamic crime and that sexual assaults can escalate to homicide when specific situational factors are present. This study simultaneously explored the utility of the sexual murderer as a unique type of offender hypothesis and sexual homicide as a differential outcome of sexual assaults hypothesis. This study is based on a sample of 342 males who were convicted of committing a violent sexual offense, which resulted in either physical injury or death of the victim. A series of latent class analyses were performed using crime scene indicators in an attempt to identify discrete groups of sexual offenders. In addition, the effects of modus operandi, situational factors, and offender characteristics on each group were investigated. Results suggest that both hypotheses are supported. A group of offenders was identified who almost exclusively killed their victims and demonstrated a lethal intent by the choice of their offending behavior. Moreover, three other groups of sex offenders were identified with a diverse lethality level, suggesting that these cases could end up as homicide when certain situational factors were present.

    Intimate partner violence (IPV) victimization is linked to sexual risk exposure among women. However, less is known about the intersection of IPV perpetration and sexual risk behavior among men. This study used data from a diverse, community sample of 334 heterosexually active young men, aged 18 to 25, across the United States to examine whether and how men with distinct IPV-related behavior patterns differed in sexual risk-related behavior and attitudes. Participants were recruited and surveyed online, and grouped conceptually based on the types of IPV perpetration behavior(s) used in a current or recent romantic relationship. Groups were then compared on relevant sexual risk variables. Men reporting both physical abuse and sexual coercion against intimate partners reported significantly higher numbers of lifetime partners, higher rates of nonmonogamy, greater endorsement of nonmonogamy, and less frequent condom use relative to nonabusive men or those reporting controlling behavior only. This group also had higher sexually transmitted infection (STI) exposure compared to men who used controlling behavior only and men who used sexual coercion only. Findings suggest that interventions with men who use physical and sexual violence need to account for not only the physical and psychological harm of this behavior but also the sexual risk to which men may expose their partners.

    Risky sexual behavior poses significant health risks by increasing sexually transmitted infections and unintended pregnancies. Previous research has documented many factors related to risky sexual behavior. This study adds to the literature by proposing a prospective, developmental model of peer factors related to risky sexual behavior. Developmental pathways to risky sexual behavior were examined in a sample of 517 individuals (51% female; 82% European American, 16% African American, 2% other) followed from age 5-27. Structural equation models examined direct and indirect effects of peer rejection (assessed via peer nominations at ages 5, 6, 7, and 8), affiliation with deviant peers (assessed via self-report at ages 11 and 12), and delinquency (assessed via maternal report at ages 10 and 16) on risky sexual behavior (assessed via self-report at age 27). More peer rejection during childhood, affiliation with deviant peers during pre- adolescence, and delinquency in childhood and adolescence predicted more risky sexual behavior through age 27, although delinquency at age 16 was the only risk factor that had a significant direct effect on risky sexual behavior through age 27 above and beyond the other risk factors. Peer rejection was related to subsequent risk factors for girls but not boys. Peer risk factors as early as age 5 shape developmental pathways through childhood and adolescence and have implications for risky sexual behavior into adulthood.

    Gender-based violence is a key determinant of HIV infection among women in South Africa as elsewhere. However, research has not examined potential mediating processes to explain the link between experiencing abuse and engaging in HIV sexual risk behavior. Previous studies suggest that alcohol use and mental health problems may explain how gender-based violence predicts sexual risk. In a prospective study, we examined whether lifetime history of gender-based violence indirectly affects future sexual risk behavior through alcohol use, depression and post-traumatic stress disorder (PTSD) in a high-risk socio-environmental context. We recruited a cohort of 560 women from alcohol drinking venues in a Cape Town, South African township. Participants completed computerized interviews at baseline and 4 months later. We tested prospective mediating associations between gender-based violence, alcohol use, depression, PTSD, and sexual risk behavior. There was a significant indirect effect of gender-based violence on sexual risk behavior through alcohol use, but not mental health problems. Women who were physically and sexually abused drank more, which in turn predicted more unprotected sex. We did not find a mediated relationship between alcohol use and sexual risk behavior through the experience of recent abuse or mental health problems. Alcohol use explains the link between gender-based violence and sexual risk behavior among women attending drinking venues in Cape Town, South Africa. Efforts to reduce HIV risk in South Africa by addressing gender-based violence must also address alcohol use.

    Relationships among alcohol use, strength of religious convictions, and unsafe sexual practices of 210 students at a large public university in the "bible belt" were examined. The women with strong religious beliefs consumed less alcohol and were less likely to engage in risky sexual behavior than were female participants with weaker religious convictions. Among the men, religious conviction was not significantly correlated with alcohol consumption or risky sexual behavior, but alcohol consumption and inconsistent use of condoms and multiple sexual partners were significantly correlated. Men had higher rates of alcohol consumption and unprotected sexual activity than women did, yet the two groups did not differ in overall frequency of sexual activity. Future research is needed to (a) provide greater understanding of gender differences in alcohol use, risky sexual behavior, and religious beliefs of college students in the region and (b) determine whether similar correlations exist in other areas of the country.

    Maternal behavior in mice is considered to be sexually dimorphic; that is, females show maternal care for their offspring, whereas this behavior is rarely shown in males. Here, we examined how social isolation affects the interaction of adult male mice with pups. Three weeks of isolation during puberty (5-8 weeks old) induced retrieving and crouching when exposed to pups, while males with 1 week isolation (7-8 weeks old) also showed such maternal care, but were less responsive to pups. We also examined the effect of isolation during young adulthood (8-11 weeks old), and found an induction of maternal behavior comparable to that in younger male mice. This effect was blocked by exposure to chemosensory and auditory social signals derived from males in an attached compartment separated by doubled opaque barriers. These results demonstrate that social isolation in both puberty and postpuberty facilitates male maternal behavior in sexually naïve mice. The results also indicate that air-borne chemicals and/or sounds of male conspecifics, including ultrasonic vocalization and noise by their movement may be sufficient to interfere with the isolation effect on induction of maternal behavior in male mice.

  5. Effect of sexual behavior change on long-term human immunodeficiency virus prevalence among homosexual men.

    1994-08-01

    Substantial changes in human immunodeficiency virus (HIV)-related sexual behavior have been reported by virtually every survey of homosexual/bisexual men in the last decade. This paper uses a behavior-based simulation to examine how such changes are likely to affect the long-term future of the acquired immunodeficiency syndrome (AIDS) epidemic among homosexual men. Data from the Longitudinal AIDS Impact Project in New York City are used to estimate age-specific patterns of unprotected anogenital contact and behavioral change from 1980 to 1991. Model projections are validated using New York City surveillance data on AIDS incidence from 1981 to 1991. The current levels of unsafe sex reported in the Longitudinal AIDS Impact Project are shown to be almost exactly on the epidemic threshold. If this behavior were maintained, HIV prevalence would slowly decline in the population, but with just one additional unsafe sexual partner per year HIV would instead become endemic, with seroprevalence of about 65% in the oldest group and about 25% in the youngest. Transmission dynamics in the youngest group are analyzed in detail. For this group, the assortative age-matching bias in partner selection patterns raises the unsafe behavior threshold slightly in the long run. PMID:8030625

    Purpose: This paper presents the findings of a cross-sectional survey on the risk and protective factors of premarital sexual behavior among rural female adolescents in Peninsular Malaysia. Methods: We investigated data on 770 female respondents aged 13-17 years in rural areas to identify predictive factors for premarital sexual intercourse. Data were analyzed using bivariate and multivariate regression. Specific socio-demographic factors, psychological and family domains, peer delinquency, and knowledge and attitudes about sexuality were considered in risky sexual behaviors in rural Malay girls. The effects of other covariates for premarital sexual intercourse were controlled by logistic regression model. Results: Of the 770 rural female students, about 3.2% of respondents reported experience of sexual intercourse in the past three months. Out of those sexually active girls, 36% were 17 years old and 20% stated having sexual intercourse with more than one partner, and 72% did not use contraception during the most recent sexual intercourse. Midnight activities, peer-sexual disorder, self-evaluation, and attitude toward sexual health were significant predictors of sexual intercourse in rural girls in Malaysia. Conclusion: The finding highlights the impact of psychological factors and peer group influences on the challenges of premarital sexual behavior among rural girls and the notion of school-based sexual health education for adolescents. This study triggers other researchers take into account a comprehensive view of protective factors operating in adolescents’ risky sexual behaviors in Asian culture seeing that family domain variables, unexpectedly, exerted no predicting influence on sexually active female teens in rural areas in Malaysia.

    Childhood sexual abuse (CSA) is associated with sexual risk behavior in adulthood, but little research has investigated processes that might mediate this relation. The purpose of this study was to investigate whether constructs suggested by the traumagenic dynamics (TD) model (a theory of the effects of CSA) or constructs suggested by the Information-Motivation-Behavioral skills (IMB) model (a theory of the antecedents of sexual risk behavior) better mediated the relation between CSA and sexual risk behavior in adulthood. Participants were 481 women attending an STI clinic (66% African American) who completed a computerized survey as well as behavioral simulations assessing condom application and sexual assertiveness skills. Forty-five percent of the sample met criteria for CSA and CSA was associated with sexual risk behavior in adulthood. In multiple mediator models, the TD constructs mediated the relation between CSA and the number of sexual partners whereas the IMB constructs mediated the relation between CSA and unprotected sex. In addition, the TD constructs better mediated the relation between CSA and the number of sexual partners; the TD and IMB constructs did not differ in their ability to mediate the relation between CSA and unprotected sex. Sexual risk reduction interventions for women who were sexually abused should target not only the constructs from health behavior models (e.g., motivation and skills to reduce sexual risk), but also constructs that are specific to sexual abuse (e.g., traumatic sexualization and guilt).

    only 36% of the schools provided a course, or a course unit, in sex education, and in most of these schools, students were not required to take the course. Efforts must be made to rectify this situation in light of the extensiveness of adolescent sexual problems in the US. The proportion of young teenagers who engage in sexual activity is increasing, and the use of contraception among young teenagers is totally inadequate. In 1976 there were 780,000 premarital pregnancies among teenagers, and most teenage mothers leave school. Little is known about male adolescent sexual behavior, yet many teenagers rely on male contraceptive methods. Recent retrenchment in the financing for federal programs, and the efforts of the conservative right wing to curtail adolescent access to family planning services, threatens the progress made during the 1970s.

    Although negative racial stereotypes may affect the mental and physical health of African Americans, little research has examined the influence of positive or complimentary racial stereotypes on such outcomes. More specifically, this study explored the relationship between African American women’s endorsement of complimentary stereotypes about their sexuality (CSS) and attitudes/behaviors that have been associated with sexual risk. Data were gathered from 206 African American women as part of the Black Women in the Study of Epidemics project (B-WISE). Multivariate regression models were used to examine associations between women’s endorsement of CSS and selected sex-related attitudes and behaviors. Participants’ endorsement of CSS was significantly positively associated with beliefs that having sex without protection would strengthen their relationship (B = .28, SE = .10, p < .01) and that they could use drugs and always make healthy choices about using protection (B = .31, SE = .09, p < .01). Significant positive associations were also found between CSS and the number of casual sexual partners women reported in the past year (B = .29, SE = .15, p = .05) and their willingness to have sex in exchange for money or drugs during that time (B = .78, OR = 2.18, p < .05). These findings suggest that endorsement of CSS by African American women can lead to increased risk behavior, particularly relating to possible infection with HIV or other sexually transmitted infections (STI).

    This study analyzes the impact of a neurotoxic lesion of the central noradrenergic system on the pharmacological reversal of the sexual inhibition present at sexual exhaustion, by IP treatment with yohimbine (2 mg/kg), 8-hydroxy-2-(di-n-propylamino)tetralin (8-OH-DPAT) (0.25 mg/kg), and naloxone (3 mg/kg). All drugs, at the doses tested, were able to increase the percentage of sexually exhausted intact rats showing copulatory behavior 24 h after a sexual satiation session. In N-(2-chloroethyl)-N-ethyl-2-2-bromobenzylamine (DSP4)-lesioned, sexually exhausted animals, naloxone and 8-OH-DPAT lost their stimulatory effect on sexual behavior; yohimbine treatment was still able to markedly increase the percentage of satiated rats mounting, intromitting, and exhibiting the ejaculatory motor pattern, but inhibited seminal emission. The data strongly suggest that the integrity of the central noradrenergic system is essential for the pharmacological reestablishment of copulatory behavior in sexually exhausted rats. Results are in line with previous data showing that the sexual behavioral variables more directly addressing motivational components are severely affected by sexual satiation. PMID:8535863

    2013-01-01

    There are dramatic individual differences among adolescents in how and when they become sexually active adults, and “early” sexual activity is frequently cited as a cause of concern for scientists, policymakers, and the general public. Understanding the causes and developmental impact of adolescent sexual activity can be furthered by considering genes as a source of individual differences. Quantitative behavioral genetics (i.e., twin and family studies) and candidate gene association studies now provide clear evidence for the genetic underpinnings of individual differences in adolescent sexual behavior and related phenotypes. Genetic influences on sexual behavior may operate through a variety of direct and indirect mechanisms, including pubertal development, testosterone levels, and dopaminergic systems. Genetic differences may be systematically associated with exposure to environments that are commonly treated as causes of sexual behavior (gene-environment correlation). Possible gene-environment correlations pose a serious challenge for interpreting the results of much behavioral research. Multivariate, genetically-informed research on adolescent sexual behavior compares twins and family members as a form of “quasi-experiment”: How do twins who differ in their sexual experiences differ in their later development? The small but growing body of genetically-informed research has already challenged dominant assumptions regarding the etiology and sequelae of adolescent sexual behavior, with some studies indicating possible positive effects of teenage sexuality. Studies of gene × environment interaction may further elucidate the mechanisms by which genes and environments combine to shape the development of sexual behavior and its psychosocial consequences. Overall, the existence of heritable variation in adolescent sexual behavior has profound implications for environmentally-oriented theory and research. PMID:23855958

Our understanding of the international epidemiology of child sexual abuse is considerably greater than it was just 10 years ago, and studies from around the world are examined. Childhood sexual abuse can involve a wide number of psychological sequelae, including low self-esteem, anxiety, and depression. Numerous studies have noted that child sexual abuse victims are vulnerable to later sexual revictimization, as well as the link between child sexual abuse and later engagement in high-risk sexual behaviour. Survivors of child sexual abuse are more likely to have multiple sex partners, become pregnant as teenagers, and experience sexual assault as adults. Various models which attempt to account for this inter-relationship are presented; most invoke mediating variables such as low self-esteem, drug/alcohol use, PTSD and distorted sexual development. Prevention strategies for child sexual abuse are examined including media campaigns, school-based prevention programmes, and therapy with abusers. The results of a number of meta-analyses are examined. However, researchers have identified significant methodological limitations in the extant research literature that impede the making of recommendations for implementing existing therapeutic programmes unreservedly.

    Previous studies have showed that lesions in the bed nucleus of the stria terminalis of experienced male rats impair some parameters of sexual behavior. The aim of this study was to examine the contribution of the medial posterior region of the bed nucleus of the stria terminalis (BSTMP), a sexually dimorphic region of this nucleus that pertains to the vomeronasal system, to the modulation of sexual behavior of the male rat. Small electrolytic bilateral lesions in the BSTMP were made in male heterosexual experienced and inexperienced rats. Sham lesioned animals were also tested as a control of the effects of the general surgical procedures. Behavioral tests were then performed to obtain standard measures of masculine sexual behavior. Our results indicate that the sexually experienced male rats with lesioned BSTMPs showed increases in the number of mounts and the number of intromissions and, consequently, in ejaculation latency. In contrast, the sexually naive male rats showed increases in first mount and intromission latencies and in ejaculation latency, but the latter occurred due to increases in the interintromission intervals. This group also showed low correlations between olfactory investigation of the anogenital area of the female and initiation and maintenance of copulatory behavior. The results suggest that sexual experience obtained in the very artificial conditions of laboratory tests could supply some of the cues provided by the BSTMP in the process of sensorial integration, which we hypothesize modulates the initiation and pacing of copulation. However, sexual experience does not apparently supply any other kinds of cues provided or processed in the BSTMP that are involved in modulating the elicitation of intromissions and ejaculations.
