This study observed that inhibiting androgenic activity during early postnatal development significantly decreased body weight in female rats by day 90, while affecting food intake and fat distribution in both sexes based on the inhibited testosterone metabolic pathway.

This review examines the negative effects of anabolic-androgenic steroid use on the male reproductive system, including impaired testosterone production, sperm production issues, and adverse metabolic consequences without reporting new clinical results.

This study observed that the catagen phase in hairless mice displayed a slower shortening of the mutant epithelial column, resulting in longer total follicle length and abnormalities in the connective tissue sheath and glassy membrane.

This case study highlights a testosterone- and cortisol-secreting adrenal oncocytic neoplasm in an 18-year-old woman, illustrating the role of surgical excision in resolving hyperandrogenism and restoring menstruation.

GABAergic steroid precursors reduce ethanol withdrawal symptoms in certain mice.

In this study, prenatal androgen exposure was linked to altered sexual behaviors in both male and female mice, with specific effects on mounting and lordosis behaviors.

In this study, daily administration of 100mg DHEA for 16 weeks in women with adequate ovarian reserve did not modify metabolic or reproductive variables, apart from increased antral follicular count and anti-Müllerian hormone levels.

This study found that finasteride significantly reduced prostate weight and DHT levels in male mastomys, but not in females, suggesting unique androgen metabolism in female prostates.

This study suggested that moxibustion treatment before or at the early stage of diminished ovarian reserve in rats may improve ovarian function by modulating androgen balance, though its effects differ across intervention timings.

This study details a 15-year-old girl with secondary amenorrhea and other symptoms who was found to have a pituitary mass causing multiple hormonal deficiencies, diagnosed as lymphocytic hypophysitis.

This study observed that equine epididymis mainly expresses the type 1 isoform of 5α-reductase and effectively converts progesterone and testosterone to DHP and DHT, while finasteride and dutasteride inhibited this activity.

Women with pituitary adenomas often have reproductive issues, like irregular periods and trouble getting pregnant, but not always breast milk production without pregnancy.

This review discusses various noninflammatory alopecias in horses, particularly alopecia areata, and reports no new treatment results, emphasizing the need for differential diagnosis through examination and biopsy.

This study found that estrogen treatment induced premature catagen and apoptosis in hair follicles of wild-type mice, while having no effect on mice lacking estrogen receptor α.

This study found that androgenic hormone levels did not explain growth differences between furless and furred male rabbits, despite a potential growth advantage in furless rabbits.

This study found that blocking the hypothalamic-pituitary-gonadal axis in male rats reduced baroreflex dysfunction and inflammation caused by endotoxemia, highlighting potential therapeutic benefits.

This study found that administering a supraphysiological dose of testosterone to female rats significantly reduced estrogen and progesterone levels, disrupted sex steroid receptor expression, and interfered with the embryonic implantation window, indicating potential implications for androgen-related endometrial conditions.

This study observed that circulating testosterone affects baseline sex differences in voiding function in C57BL/6J mice, with prostate lobe mass having a lesser impact.

This study did not find any significant effects of estradiol or its antagonists on hair growth in two common mouse strains, challenging previous results reported by Oh and Smart.

In this study, a new hairless gene in the Donryu rat strain was identified, showing skin similarities to human skin tumors with multiple follicular cysts.

This study found that deslorelin may promote hair regrowth in intact male dogs with hair cycle arrest, but had no effect on neutered females.

This study observed that adult female acne may be associated with hyperandrogenic features and polycystic ovary syndrome, though routine hormonal tests often do not show abnormalities other than PCOS.

This study in female beagle dogs found that long-term exposure to oral contraceptive steroids resulted in significant reproductive and mammary gland changes, with the relevance to human tumor risk remaining uncertain.

In this study, researchers discovered that the MafB gene, which is important for macrophage differentiation, shows high expression in the pancreas and is influenced by sex steroids, with varied expression patterns in hamster tissues and during reproductive phases.

This review discusses the reproductive challenges and potential pathophysiological mechanisms related to anorexia nervosa, noting possible long-term effects on fertility and pregnancy outcomes.

This paper discusses the lack of a genetic model for androchronogenic alopecia in rodents, noting the stumptailed macaque as a better current model due to its similarities to human male-pattern baldness; it reports no new results.

This study reported a rare case of ovarian steroid cell tumor removal resulting in normalized hormone levels, resumption of menstruation, and subsequent spontaneous pregnancy in a 31-year-old woman.
