We previously found that female mice exhibited Fos responses in the accessory olfactory bulb (AOB) after exposure to volatile opposite-sex, but not same-sex, urinary odours. This effect was eliminated by lesioning the main olfactory epithelium, raising the possibility that the AOB receives information about gender via centrifugal ...

The current study was designed to examine the modulating effects of bisphenol A (BPA) on prostate cancer risk in male offspring exposed transplacentally and lactationally. BPA was administered to F344 female rats by gavage at 0, 0.05, 7.5, 30, 120 mg/kg/day during pregnancy and lactation periods. When F1 males reached 5 weeks old, they were given 10 subcutaneous injections of ...

In order to determine whether the secretion of androgen by the ovary of the adult rat increases after x irradiation, irradiated ovaries were implanted into castrated male litter-mates, and pieces of prostate into both x-irradiated and normal female rats. The grafts of irradiated ovaries failed to vascularize and grow, and did not appear to secrete androgen, as judged by the weight of the ...

Boric acid (H3BO3), an inorganic acid with widespread commercial use and consumer exposure, impairs fertility in male rodents at dose levels lower than those required to cause other adverse effects. Previous studies found a testicular lesion in adult Fischer rats fed 9000 ppm boric acid (1575 ppm boron) and slightly reduced basal serum testosterone levels. A CNS-mediated hormonal component to this ...

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, ...

The extragonadal source of the high levels of 5 alpha-reduced androgens in the peripheral blood of the male rabbit has been investigated. Adult 3-day castrated rabbits each received a single intravenous injection of 3H-labelled testosterone, and blood plasma was collected at various intervals thereafter. Two h post injection, animals were killed, various accessory ...

Rapid industrialization has increased the burden of chemicals in the environment. These chemicals may be harmful to development and reproduction of any organism. We therefore analyzed the adverse effects of leachates from a tannery solid waste on development and reproduction using Drosophila. We show a significant delay in mean emergence of flies observed at the higher ...

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.

The rodent Hershberger assay is being validated as an in vivo test method for detecting androgenic or antiandrogenic compounds by the Organization for Economic Cooperation and Development (OECD). As part of the international validation work, we studied 17alpha-methyltestosterone for evaluating androgenic activity, and procymidone and p,p'-DDE for evaluating antiandrogenic ...

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 activity in ...

Prostate cancer, the most prevalent non-cutaneous cancer in men, is associated with increased age. This suggests that dietary chemopreventive measures could be effective in delaying the onset or decreasing the severity of the disease. We utilized the Lobund-Wistar rat nitrosomethylurea induced, testosterone promoted (NMU-T) model of male sex accessory ...

Previous research suggests that volatile body odourants detected by the main olfactory epithelium (MOE) are processed mainly by the main olfactory bulb (MOB) whereas nonvolatile body odourants detected by the vomeronasal organ (VNO) are processed via the accessory olfactory bulb (AOB). We asked whether urinary volatiles from males and females ...

Rapid ejaculation is probably the most common form of male sexual dysfunction. Current research into the treatment of the condition has focused on centrally acting or topical desensitizing agents; however, no treatment has yet been approved. An alternative approach could be to develop drugs that act directly upon the target organ itself and our increasing knowledge of the ...

Androgen action on sex accessory organs influences rodent fertility, but the mechanisms remain unclear and investigation is difficult without the ability to restrict androgen action in specific tissues. We used Cre-LoxP technology to generate male mice with prostate epithelial-specific androgen receptor deficiency (denoted PEARKO). In ...

In male rats, experimentally induced diabetes mellitus has been reported to be associated with reduced serum levels of gonadotropins and testosterone as well as decreased sex accessory organ weights. The purpose of the present study was to determine if the decreased accessory organ weights and ...

BackgroundInternal reproductive organ size is an important determinant of male reproductive success. While the response of testis length to variation in the intensity of sperm competition is well documented across many taxa, few studies address the importance of testis size in determining other components of male reproductive success (such as mating frequency) or the ...

Non-volatile chemosignals in rodents are detected by unique receptors in the vomeronasal organ of the accessory olfactory system. Although the vomeronasal organ has been implicated in the regulation of sexually dimorphic behavioral and neuroendocrine functions, the underlying cellular mechanisms are undetermined. In previous studies we ...

Induction and branching morphogenesis of the prostate are dependent on androgens, which act via the mesenchyme to induce prostatic epithelial development. One mechanism by which the mesenchyme may regulate the epithelium is through secreted growth factors such as FGF-10. We have examined the male reproductive tract of FGF-10(-/-) mice, and at birth, most of the male secondary ...

Following chronic (15 or 30 days) treatment with oestradiol 3-benzoate (75 microg rat(-1) day(-1) in 100 microl of olive oil) to adult rats, androgen receptor (AR) expression was analysed simultaneously in testis, epididymis, seminal vesicle, prostate and pituitary utilising three independent tools i.e. immunohistochemistry, Western blotting and RT-PCR. All the five organs ...

In internally fertilizing organisms, mating involves a series of highly coordinated molecular interactions between the sexes that occur within the female reproductive tract. In species where females mate multiply, traits involved in postcopulatory interactions are expected to evolve rapidly, potentially leading to postmating-prezygotic (PMPZ) reproductive ...

Ceratotoxins are antibacterial peptides produced in the female reproductive accessory glands of the medfly Ceratitis capitata. Their expression is not affected by bacterial infection, but is enhanced after mating and is modulated by juvenile hormone. Three different peptides, named ceratotoxins A, B and C, have been previously purified from the female ...

Brain-derived neurotrophic factor (BDNF) is a growth factor belonging to the family of neurotrophins. Although neurotrophins in the male genital organs have been well documented, their role in the biology of these organs is far from clear. In particular, little is known about the influence of sex hormones on neurotrophin expression. In ...

The OECD has proposed a new, validated test guideline with the stimulated weanling male Hershberger assay to avoid the surgical castration step. In the present study, we assessed the relevance and reliability of the stimulated weanling Hershberger assay in four stages. All chemicals except for testosterone propionate (TP) were orally administered to sexually immature male rats of 22 days old for ...

The distribution and function of an Aplysia cardioexcitatory peptide, NdWFamide, were examined in the nervous system of pulmonate snails. We chemically identified the authentic NdWFamide from a land snail (Euhadra congenita) and a freshwater snail (Lymnaea stagnalis). NdWFamide potentiated the heartbeat of those snails. Immunohistochemistry using anti-NdWFamide antibody demonstrated the ...

We established an inbred rat strain with unilateral urogenital anomalies from an incidentally identified male rat with unilateral renal agenesis and an undescended left testis. These rats were characterized by unilateral renal agenesis in both sexes, undescended testes with agenesis and hypoplasia of the accessory sex ...

As a participating laboratory for the OECD Hershberger validation program, we conducted a phase 3 trial to test the reliability of the Hershberger assay using coded substances. Male Sprague-Dawley rats were castrated at 6 weeks of age and allowed to recover for 8 days. All the coded substances were administered orally once daily for 10 consecutive days. In the antagonist version of the assay, 0.4 ...

Hedgehog (Hh) proteins are expressed during vertebrate development in some tissues with inductive properties and at epithelial-mesenchymal boundaries in several developing organs, including the lung, gut, hair follicle, and tooth. The Hh signaling pathway is highly conserved, and important clues to understanding the mechanism of Hh signal transduction in vertebrates have come ...

For many organisms, pheromonal communication is of particular importance in managing various aspects of reproduction. In tetrapods, the vomeronasal (Jacobson's) organ specializes in detecting pheromones in biological substrates of congeners. This information triggers behavioral changes associated, in the case of certain pheromones, with neuroendocrine ...

The Organization for Economic Co-operation and Development (OECD) has initiated the development of new guidelines for the screening and testing of potential endocrine disrupters. The Hershberger assay is one of the assays selected for validation based on the need for in vivo screening to detect androgen agonists or antagonists by measuring the response of five ...

We evaluated the effects of three rodent diets differing in soybean meal content on the response of the seminal vesicles, prostate and bulbocavernosus/levator ani (BC/LA) muscle to androgens and anti-androgenic compounds in the Hershberger assay. The diets tested were (1) L5, a semi-synthetic phytoestrogen-free diet, (2) DO4, 8.5% (w/w) vegetable protein and (3) DO3, 22.5% (w/w) vegetable protein. ...

To determine if Butea superba Roxb., a traditional Thai male potency herb, has androgenic activity in 60-day-old male Wistar rats, we measured its effects on the pituitary-testicular axis and sex organs. Intact and orchidectomized adult male rats were subdivided into five groups (10 rats/group): distilled water, Butea superba (BS)-10, BS-50, BS-250, and ...
