Effect of androgens on the cranial suspensory ligament and ovarian position. (1/55)

Androgens have been postulated to have a major role in testicular descent via regression of the cranial suspensory ligament, which in normal rodents anchors the ovary to the retroperitoneum near the lower pole of the kidney. This study aimed to quantitate the degree of descent of the foetal ovary in androgen-treated female mice to determine the role of androgens in regression of the cranial suspensory ligament and descent of the testis. Time-pregnant mice were injected with testosterone propionate or methyl testosterone (2.5-3.0 mg) in vehicle on day 13 or 14. Control animals received vehicle only. Newborn mice were anaesthetised and dissected for macroscopic anatomy of the ovary, which was quantified by measuring the vertical distance from the lower pole of the kidney to the lower pole of the ovary. Histological analysis was also performed. The external genitalia were masculinised in all females exposed to prenatal androgens. The ovaries of treated animals were mobile, with no cranial suspensory ligament, and located slightly caudal to the kidney. Wolffian duct structures were identifiable, but the gubernaculum was qualitatively unchanged compared with control females. The ovary was displaced caudally (P< 0.001), but only 15-25% of the distance to the lower abdomen. Exogenous androgens induce regression of the cranial suspensory ligament, causing the ovary to be more mobile and lower in the abdominal cavity. However, since the testicular position at birth is at or below the bladder neck, androgen-mediated regression of the cranial suspensory ligament is only an adjunct to the control of transabdominal testicular descent.  (+info)

Anabolic steroids induce region- and subunit-specific rapid modulation of GABA(A) receptor-mediated currents in the rat forebrain. (2/55)

Anabolic-androgenic steroids (AAS) have become significant drugs of abuse in recent years with the highest increase reported in adolescent girls. In spite of the increased use of AAS, the CNS effects of these steroids are poorly understood. We report that in prepubertal female rats, three commonly abused AAS, 17alpha-methyltestosterone, stanozolol, and nandrolone, induced rapid and reversible modulation of GABAergic currents in neurons of two brain regions known to be critical for the expression of reproductive behaviors: the ventromedial nucleus of the hypothalamus (VMN) and the medial preoptic area (mPOA). All three AAS significantly enhanced peak synaptic current amplitudes and prolonged synaptic current decays in neurons of the VMN. Conversely all three AAS significantly diminished peak current amplitudes of synaptic currents from neurons of the mPOA. The endogenous neuroactive steroids, 3alpha-hydroxy-5alpha-pregnan-20-one and 5alpha-androstane-3alpha,17beta-diol, potentiated currents in the VMN as did the AAS. In contrast to the negative modulation induced by AAS in the mPOA, the endogenous steroids potentiated responses in this region. To determine the concentration response relationships, modulation by the AAS, 17alpha-methyltestosterone (17alpha-meT), was assessed for currents evoked by ultrafast perfusion of brief pulses of GABA to acutely isolated neurons. Half-maximal effects on currents elicited by 1 mM GABA were elicited by submicromolar concentrations of AAS for neurons from both brain regions. In addition, the efficacy of 10(-5) to 10(-2) M GABA was significantly increased by 1 microM 17alpha-meT. Previous studies have demonstrated a striking dichotomy in receptor composition between the VMN and the mPOA with regard to gamma subunit expression. To determine if the preferential expression of gamma(2) subunit-containing receptors in the VMN and of gamma(1) subunit-containing receptors in the mPOA could account for the region-specific effects of AAS in the two regions, responses elicited by ultrafast perfusion of GABA to human embryonic kidney 293 cells transfected with alpha(2), beta(3), and gamma(2) or alpha(2), beta(3), and gamma(1) subunit cDNAs were analyzed. As with native VMN neurons, positive modulation of GABA responses was elicited for alpha(2)beta(3)gamma(2) recombinant receptors, while negative modulation was induced at alpha(2)beta(3)gamma(1) receptors as in the mPOA. Our data demonstrate that AAS in doses believed to occur in steroid abusers can induce significant modulation of GABAergic transmission in brain regions essential for neuroendocrine function. In addition, the effects of these steroids can vary significantly between brain regions in a manner that appears to depend on the subunit composition of GABA(A) receptors expressed.  (+info)

Future possibilities in the prevention of breast cancer: luteinizing hormone-releasing hormone agonists. (3/55)

The cyclic production of estrogen and progesterone by the premenopausal ovary accounts for the steep rise in breast cancer risk in premenopausal women. These hormones are breast cell mitogens. By reducing exposure to these ovarian hormones, agonists of luteinizing hormone-releasing hormone (LHRH) given to suppress ovarian function may prove useful in cancer prevention. To prevent deleterious effects of hypoestrogenemia, the addition of low-dose hormone replacement to the LHRH agonist appears necessary. Pilot data with such an approach indicates it is feasible and reduces mammographic densities.  (+info)

Effects of 17alpha-methyltestosterone on seminal vesicle development and semen release response in the African catfish, Clarias gariepinus. (4/55)

The effects of 17alpha-methyltestosterone on seminal vesicle development in the African catfish, Clarias gariepinus, were investigated in an attempt to improve semen collection from this species. Treatment of larvae with dietary 17alpha-methyltestosterone at 50 mg kg(-1) for days 12-33 or days 12-40 after hatching, or at 20 mg kg(-1) for days 12-26, 12-33, 12-40 or 12-47 after hatching inhibited the development of the seminal vesicle finger-like extensions in male catfish, but did not affect the sex ratio. The minimum effective dose and period of treatment to inhibit seminal vesicle development in all male catfish treated with 17alpha-methyltestosterone was 20 mg kg(-1) for days 12-40 after hatching. Male catfish from this treatment group developed normal testes that, in some cases, contained a few oocytes, which tended to disappear before sexual maturation. After sexual maturation, the semen release response was evaluated in males with incomplete seminal vesicles. Fluid with viable spermatozoa was obtained after two consecutive injections of carp pituitary suspension, from 10 of 19 males that had been fed 20 mg 17alpha-methyltestosterone kg(-1) for days 12-40 or days 12-47 after hatching, but from only 4 of 15 males that did not receive any dietary steroid. Intratesticular semen quality was not affected by 17alpha-methyltestosterone treatment. The results of this study demonstrate that the absence of seminal vesicle extensions induced by treatment with 17alpha-methyltestosterone facilitated the collection of semen by stripping from this species of fish.  (+info)

Quantitative evaluation of virilizing activity of steroids by measuring morphological changes in uro-genital region of rats. (5/55)

A new technique to measure the uro-genital parameters such as the lengths of urovaginal septum, corpora cavernosa and anogenital distance on the sagittal sections of the pelvic region of female fetus of rat under microscope equipped with a micrometer was developed. In the examination of 180 normal female fetuses on the 21st day of gestation, relationships were observed between the fetal body weight and the length of urovaginal septum as well as anogenital distance, but not on the length of corpora cavernosa. Following maternal subcutaneous administration of various doses of 17alpha-methyltestosterone between the 17th and 20th day of gestation, dose-dependent abridgment in urovaginal septum length and extensions in corpora cavernosa length and anogenital distance were observed in female fetus on the 21st day's examination. When these three parametars were calculated on the relative value to the fetal body weight, however, linear relationships against log-dose were observed in all parameters. Among these three parameters the abridgment in urovaginal septum was shown to be the most sensitive. A quantitative assay of virilizing activity of steroids in female fetuses was examined on rats treated subcutaneously with 17alpha-methyltestosterone and norethandrolone. Linear regressions against the log-doses of both steroids were demonstrated in urovaginal septum length, and parallelism was noted between both regression lines. The relative potency of norethandrolone to 17alpha-methyltestosterone calculated on urovaginal septum length was 0.354 with fiducial limits of 0.293-0.44l, and it was suggested that the virilizing activities of steroids can be evaluated quantitatively.  (+info)

Androgens and the development of the vagina. (6/55)

Today it is generally held that the vagina develops from sinovaginal bulbs and that the lower third of the definitive vagina is derived from the urogenital sinus. Here we show that the entire vagina arises by downward growth of Wolffian and Mullerian ducts, that the sinovaginal bulbs are in fact the caudal ends of the Wolffian ducts, and that vaginal development is under negative control of androgens. We designed a genetic experiment in which the androgen receptor defect in the Tfm mouse was used to examine the effects of androgens. Vaginal development was studied by 3D reconstruction in androgen-treated female embryos and in complete androgen-insensitive littermates. In androgen-treated females, descent of the genital ducts was inhibited, and a vagina formed in androgen-insensitive Tfm embryos as it does in normal females. By immmunohistochemical localization of the androgen receptor in normal mouse embryos, we demonstrated that the androgen receptor was expressed in Wolffian duct and urogenital sinus-derived structures, and was entirely absent in the Mullerian duct derivatives. We conclude that the Wolffian ducts are instrumental in conveying the negative control by androgens on vaginal development. The results are discussed under evolutionary aspects at the transition from marsupial to eutherian mammals.  (+info)

Chronic administration of anabolic steroids disrupts pubertal onset and estrous cyclicity in rats. (7/55)

Use of anabolic-androgenic steroids (AASs) is becoming increasingly popular among adolescent girls, yet the effects of AASs on female physiology and development are not well understood. The present study compared the effects of chronic exposure to three individual AASs, stanozolol (0.05-5 mg/kg), 17alpha-methyltestosterone (0.5-5 mg/kg), and methandrostenolone (0.5-5 mg/kg) on the onset of puberty and estrous cyclicity in the rat. Female rats received daily injections of AASs for 30 days (Postnatal Day [PN] 21-51). Rats receiving the highest dose of each of the AASs (5 mg/kg) displayed vaginal opening at a younger age than rats receiving the oil vehicle. The day of first vaginal estrus was delayed in rats receiving stanozolol (5 mg/kg) or 17alpha-methyltestosterone (0.5-5 mg/kg) but not in rats receiving methandrostenolone. At the highest dose (5 mg/kg), each of the AASs reduced the incidence of regular estrous cyclicity during the treatment period. Concurrent administration (on PN21-51) of the androgen receptor antagonist, flutamide (10 mg/kg, twice daily), reversed the effects of 17alpha-methyltestosterone (5 mg/kg) on vaginal opening. Flutamide administration also eliminated the effects of stanozolol (5 mg/kg) and 17alpha-methyltestosterone (5 mg/kg) on the day of first vaginal estrus. In contrast, rats receiving flutamide and methandrostenolone (5 mg/kg) exhibited first vaginal estrus earlier than controls. The present results indicate that chronic exposure to AASs during development has deleterious effects on the female neuroendocrine axis and that these effects appear be mediated via multiple mechanisms.  (+info)

Influence of glucocorticoid, estrogen, and androgen hormones on transformation of human cells in vitro by feline sarcoma virus. (8/55)

Infection of human foreskin cells (D-550) by the Snyder-Theilen strain of feline sarcoma virus produced small but countable foci and demonstrated "single-hit" dose-response kinetics. Significant quantitative and qualitative enhancement of focus formation was observed when the glucocorticoid hormones, dexamethasone, hydrocortisone, cortisol acetate, and prednisolone were added to cell cultures (1.0 mug/ml) 24 hr postinfection. However, aldosterone, while inducing qualitatively larger foci, did not bring about a quantitative enhancement in total foci number. By contrast, 17beta-estradiol, progesterone, cortisone acetate, methyltestosterone, and estrone elicited little or no effect on focus induction by Snyder-Theilen feline sarcoma virus. Evidence is suggestive of a posttranscriptional effect possibly modulating viral genome expression resulting in an increased efficiency of viral transformation, and an increased proliferation of transformed cells.  (+info)

Methyltestosterone is a synthetic form of the hormone testosterone, which is primarily used in the treatment of low testosterone levels (hypogonadism) in men. It has a methyl group attached to it, which allows it to be taken orally and still have significant effects on the body.

Testosterone is an androgen hormone that plays important roles in the development and maintenance of male sex characteristics, such as deepening of the voice, growth of facial and body hair, and increased muscle mass. It also helps maintain bone density, red blood cell production, and sex drive.

Methyltestosterone is available in various forms, including tablets and capsules, and its use should be under the supervision of a healthcare professional due to potential side effects and risks associated with its use, such as liver toxicity, increased risk of cardiovascular events, and changes in cholesterol levels.

It's important to note that methyltestosterone is not approved for use in women, as it can cause virilization (development of male sex characteristics) and other side effects.

Gynecomastia is a medical term that refers to the benign enlargement of the glandular tissue in male breasts, usually caused by an imbalance of the hormones estrogen and testosterone. It's important to note that gynecomastia is not the same as having excess fat in the breast area, which is called pseudogynecomastia.

Gynecomastia can occur during infancy, puberty, or old age due to natural hormonal changes. Certain medications, medical conditions, and recreational drugs can also cause gynecomastia by affecting hormone levels in the body. In some cases, the exact cause of gynecomastia may remain unknown.

Mild cases of gynecomastia may not require treatment, but severe or persistent cases may be treated with medication or surgery to remove excess breast tissue. It's essential to consult a healthcare professional for an accurate diagnosis and appropriate treatment options if you suspect you have gynecomastia.

Testosterone is a steroid hormone that belongs to androsten class of hormones. It is primarily secreted by the Leydig cells in the testes of males and, to a lesser extent, by the ovaries and adrenal glands in females. Testosterone is the main male sex hormone and anabolic steroid. It plays a key role in the development of masculine characteristics, such as body hair and muscle mass, and contributes to bone density, fat distribution, red cell production, and sex drive. In females, testosterone contributes to sexual desire and bone health. Testosterone is synthesized from cholesterol and its production is regulated by luteinizing hormone (LH) and follicle-stimulating hormone (FSH).

An encyclopedia is a comprehensive reference work containing articles on various topics, usually arranged in alphabetical order. In the context of medicine, a medical encyclopedia is a collection of articles that provide information about a wide range of medical topics, including diseases and conditions, treatments, tests, procedures, and anatomy and physiology. Medical encyclopedias may be published in print or electronic formats and are often used as a starting point for researching medical topics. They can provide reliable and accurate information on medical subjects, making them useful resources for healthcare professionals, students, and patients alike. Some well-known examples of medical encyclopedias include the Merck Manual and the Stedman's Medical Dictionary.

Libido, in medical and psychological terms, refers to a person's overall sexual drive or desire for sexual activity. This term was first introduced by Sigmund Freud in his psychoanalytic theory, where he described it as one of the three components of human personality. Libido is influenced by biological, psychological, and social factors, and can vary significantly among individuals. It's important to note that a low or absent libido does not necessarily indicate an underlying medical issue, but could be a result of various factors such as stress, fatigue, relationship issues, mental health disorders, or hormonal imbalances. If you have concerns about your libido, it is recommended to consult with a healthcare professional for a proper evaluation and guidance.

Anabolic agents are a class of drugs that promote anabolism, the building up of body tissues. These agents are often used medically to help people with certain medical conditions such as muscle wasting diseases, osteoporosis, and delayed puberty. Anabolic steroids are one type of anabolic agent. They mimic the effects of testosterone, the male sex hormone, leading to increased muscle mass and strength. However, anabolic steroids also have significant side effects and can be addictive. Therefore, their use is regulated and they are only available by prescription in many countries. Abuse of anabolic steroids for non-medical purposes, such as to improve athletic performance or appearance, is illegal and can lead to serious health consequences.

Androgens are a class of hormones that are primarily responsible for the development and maintenance of male sexual characteristics and reproductive function. Testosterone is the most well-known androgen, but other androgens include dehydroepiandrosterone (DHEA), androstenedione, and dihydrotestosterone (DHT).

Androgens are produced primarily by the testes in men and the ovaries in women, although small amounts are also produced by the adrenal glands in both sexes. They play a critical role in the development of male secondary sexual characteristics during puberty, such as the growth of facial hair, deepening of the voice, and increased muscle mass.

In addition to their role in sexual development and function, androgens also have important effects on bone density, mood, and cognitive function. Abnormal levels of androgens can contribute to a variety of medical conditions, including infertility, erectile dysfunction, acne, hirsutism (excessive hair growth), and prostate cancer.

"Drug and narcotic control" refers to the regulation and oversight of drugs and narcotics, including their production, distribution, and use. This is typically carried out by governmental agencies in order to ensure public safety, prevent abuse and diversion, and protect the health of individuals. The goal of drug and narcotic control is to strike a balance between making sure that medications are available for legitimate medical purposes while also preventing their misuse and illegal sale.

Drug control policies may include measures such as licensing and registration of manufacturers, distributors, and pharmacies; tracking and monitoring of controlled substances; setting standards for prescription practices; and enforcement of laws and regulations related to drug use and trafficking. Narcotic control specifically refers to the regulation of drugs that have a high potential for abuse and are subject to international treaties, such as opioids.

It's important to note that while these regulations aim to protect public health and safety, they can also be controversial and have unintended consequences, such as contributing to drug shortages or creating barriers to access for people who need controlled substances for legitimate medical reasons.

The United States Department of Agriculture (USDA) is not a medical organization or entity, so it does not provide medical definitions. However, I can give you some information about what the USDA is and what it does.

The USDA is a federal executive department of the U.S. government responsible for developing and executing federal laws related to farming, forestry, and food. It was established in 1862 by President Abraham Lincoln and is headed by the Secretary of Agriculture, who is a member of the President's cabinet.

The USDA has several key missions, including:

* Promoting agricultural trade and production
* Ensuring the safety of the food supply
* Providing nutrition assistance to vulnerable populations
* Protecting natural resources and the environment
* Promoting rural development and economic stability

In terms of food and nutrition, the USDA plays an important role in setting dietary guidelines for Americans, establishing standards for school meals and other federal food programs, and regulating the safety of meat, poultry, and egg products. The agency also conducts research on agricultural and food-related topics and provides education and outreach to farmers, ranchers, and consumers.

A research subject, also commonly referred to as a "human subject" or "participant," is an individual who takes part in a research study or clinical trial. Research subjects are essential for the advancement of medical and scientific knowledge, as they provide data that can help researchers understand various phenomena, develop new treatments, and improve existing ones.

The term "research subject" emphasizes the ethical considerations involved in conducting research with human participants. It highlights the importance of protecting their rights, dignity, and well-being throughout the study. Researchers must obtain informed consent from subjects before enrolling them in a study, ensuring that they understand the purpose, procedures, potential risks, and benefits associated with the research.

Additionally, researchers are required to follow strict guidelines and regulations to minimize any harm or discomfort to the research subjects during the study. These guidelines may include requirements for data confidentiality, privacy protection, and monitoring of adverse events. Overall, treating research subjects with respect and care is crucial in maintaining the integrity of medical research and ensuring its societal benefits.

'Drug legislation' refers to the laws and regulations that govern the production, distribution, sale, possession, and use of medications and pharmaceutical products within a given jurisdiction. These laws are designed to protect public health and safety by establishing standards for drug quality, ensuring appropriate prescribing and dispensing practices, preventing drug abuse and diversion, and promoting access to necessary medications. Drug legislation may also include provisions related to clinical trials, advertising, packaging, labeling, and reimbursement. Compliance with these regulations is typically enforced through a combination of government agencies, professional organizations, and legal penalties for non-compliance.

I'm sorry for any confusion, but the 'United States Department of Homeland Security' (DHS) is not a medical term or concept. It's a cabinet department of the U.S. federal government, created in response to the September 11 attacks, with the primary responsibilities of protecting the United States from terrorism and managing border control. The DHS includes several components, including the U.S. Coast Guard, Transportation Security Administration (TSA), Federal Emergency Management Agency (FEMA), Customs and Border Protection (CBP), and Immigration and Customs Enforcement (ICE), among others.
