Professor Nelson explains that the prostate is actually a male sex accessory gland that contributes about a third of the secretions to the ejaculate for sexual reproduction.

Arginase activity has been identified in the prostate, and may be important in the synthesis of polyamines in accessory sex glands in the male. Polyamines in turn may mediate the action of androgens. Diabetic patients have disordered androgen synthesis. The purpose of this work was to evaluate the effect of L-arginine on arginase ...

The uptake and retention of 1,2-3H-testosterone in accessory sex glands, muscle and liver of streptozotocin diabetic castrated male rats, insulin-treated diabetic castrated rats and non-diabetic castrated control rats were studied at various time intervals after an intravenous injection. Diabetes reduced the retention of ...

Male insects change behaviors of female partners by co-transferring accessory gland proteins (Acps) like sex peptide (SP), with their sperm. The Drosophila sex peptide receptor (SPR) is a G protein-coupled receptor expressed in the female¿s nervous system and genital tract. While most Acps show a fa...

The seasonal chronology of the events of the reproductive cycle, and changes in the structure and function of the primary and accessory organs of the male bent-winged bat, Miniopterus schreibersii, were studied at latitude 37 degrees S in temperate southeastern Australia. The testicular cycle commenced in late spring (November), and sperm appeared in the seminiferous tubules ...

The present invention provides a number of accessory gland proteins from Drosophila. The invention also provides an accessory gland protein which is toxic to insect cells and can be used to kill or inhibit the development of insects. Methods of controllin...

The hypothesis tested in this study was that the membrane vesicles present in ram seminal plasma are of testicular origin, rather than being secreted by the accessory sex glands as has been previously reported for a number of species. Membrane vesicles were present in cellular extracts from reproductive organs and ...

The relationship between reproductive organs, circulating testosterone, and androstenedione concentration in the male sheath-tailed bat, Taphozous longimanus, was studied. The masses of testis, accessory sex gland (prostate, ampullary), and epididymides showed three peaks, one each in October, January, and April. Monthly changes in ...

Adult pallids bats collected in April or May, were maintained in short or long photoperiods (10 or 14 h light/day) for 3-6 months. In August, the short-day bats had regressed testes, epididymal spermatozoa and fully developed accessory sex glands, corresponding to the autumnal reproductive condition of field animals; long-day bats had ...

Immature male albino rats, 30 days of age, were treated with 0.3 mg nicotine/100 g body weight either orally or intraperitoneally for 30 days. All the animals were autopsied on the 61 st day, by which time they were sexually mature. Testis, epididymis, seminal vesicle, prostate gland and vas deferens were dissected out, weighed, and processed for biochemical and histological ...

Very few cases of pheochromocytoma in functional accessory adrenal glands have been documented in literature. We present a twenty-four year old Nigerian female who presented with pheochromocytoma. Investigations revealed a suprarenal mass, which was diagnosed as an accessory gland adrenal tumour at surgery. This ...

The relative importance of testosterone and prolactin in regulating growth and protein synthesis in rat accessory sex glands has been investigated. Protein synthesis was measured by incubating tissue minces in vitro with [35S]methionine and analysing labelled proteins on polyacrylamide gels containing sodium dodecyl sulphate. Plasma ...

) transferred at mating affect the reproductive success of both sexes. Such reproductive proteins often evolve proteomic method that uses whole-organism isotopic labeling to detect transferred Sfps in mated female D on three areas: (a) the effects of the full set of Sfps (and especially of accessory gland proteins

Biochemical analysis of semen was performed in six men with bilateral macro-orchidism. It has been shown that marker levels of the seminal vesicle secretion (fructose) are higher, whereas marker levels of prostatic secretion (citric acid and calcium) are lower, in these men than in those of a control group of normal men. Whether the pathogenesis of these findings was due to a benign enlargement of ...

Vinclozolin is a fungicide that has been shown to cause Leydig cell tumors and atrophy of the accessory sex glands in adult rodents. In addition, exposure of rats during pregnancy causes a pattern of malformations in the male urogenital tract. A wealth of standard toxicological s...

This study investigated progesterone receptor (PR) cDNA expression in the testes, prostate and bulbourethral glands of prepubertal calves treated experimentally with high and low doses of 17beta-oestradiol and with testosterone. Tissue samples were examined histologically and immunohistochemically for PR. Western blot analysis and quantitative PCR against PR was performed on ...

Ceratotoxins are antibacterial 3-kDa molecular mass amphiphilic peptides isolated from the female reproductive accessory glands of the medfly Ceratitis capitata. They are physiologically related to bee melittin and show amino acid sequence homology with magainin peptides. In this paper, we report the complete sequence of cDNA coding for ceratotoxin A and ...

The volumetric changes of the corpora allata (CA) during the first 15 days of imaginal life of Blatta orientalis L. (Dictyoptera, Blattidae) are studied in connection with the growth of the accessory reproductive glands (GSAM). Both, the CA and the GSAM, grow in parallel during the first 3-4 days of imaginal life, which suggests a possible functional link ...

Concentrations of organotin compounds (butyltins and phenyltins) were determined in gonad, accessory sex organs, penis, digestive gland, kidney, radula with sac, oesophagus with crop, stomach, hypobranchial gland, rectum, mantle, osphradium, ctenidium, heart, salivary gland, head ganglia and ...

We herein describe a case of accessory parotid gland tumor, including diagnosis and surgical approach. The accessory parotid gland is salivary tissue separated from the main parotid gland and lying on masseter muscle. It has secondary duct empting into the Stensen's duct. The ...

Roe deer are seasonal breeders with a short rutting season from mid-July to mid-August. The seasonality of reproductive activity in males is associated with cyclic changes between growth and involution of both testes and the accessory sex glands. This study characterizes morphological and functional parameters of these organs prior to, ...

Ultrastructure of male reproductive accessory glands and ejaculatory duct in the Queensland fruit fly (Q-fly), Bactrocera tryoni, were investigated and compared with those of other tephritid flies. Male accessory glands were found to comprise one pair of mesodermic glands and three pairs of ...

BACKGROUND: Neuroendocrine (NE) cells are frequently present in the human prostate and urethra, whereas they are lacking in the other urogenital organs. This study was undertaken as there are only few detailed studies available on the distribution, form and function of NE cells and the structure of excretory ducts of the accessory sex organs in the male ...
