Low-dose gonadotropin treatment is effective for infertility in women with PCOS, leading to high ovulation rates and comparable pregnancy rates with fewer complications.

This study found that treatment with leuprolide plus cyclic estrogen/progestin may lead to a faster and greater improvement in hirsutism compared to a standard oral contraceptive regimen.

This review discusses the multifactorial origins and pathophysiology of PCOS and highlights the effectiveness of lifestyle modifications as a first-line intervention, reporting no new research results.

This study found that the pituitary gland is crucial for normal pelage color cycles in weasels, with certain hormones influencing regrowth of pigmented or white hair after molting.

This study describes a family with X-linked gynecomastia and undervirilization in men, finding a subtle androgen receptor abnormality that may not always lead to infertility despite androgen resistance.

This study suggests that decreased SHBG levels and increased FAI, free testosterone, and DHEAS concentrations are effective in diagnosing PCOS in epidemiological studies of women of reproductive age.

This review discusses the physiological roles of ovarian androgens in follicle development and atresia, emphasizing their contributions to polycystic ovary syndrome and normal follicle maturation but provides no new clinical results.

This study defined menstrual phase-specific reference intervals for circulating androgen levels in young women, highlighting that anovulatory females showed higher androgen, LH, and FSH levels compared to ovulatory females.

This systematic review and meta-analysis reported potential risk variants for acne in genes related to inflammation and sebaceous gland function, including TNF, CYP17A1, and FST, across diverse populations.

This study suggests men with early androgenetic alopecia might have hormonal profiles similar to women with polycystic ovarian syndrome, potentially indicating risk for related health complications.

This study found that keloid tissues exhibit epithelial-mesenchymal transition-related changes and alterations in gene expression, implicating these processes in the pathogenesis of keloids.

This study found that Florida manatees have unique types of specialized nerve endings in their vibrissae, which assist in their sensory and manipulative functions in aquatic environments.

In this study, ketoconazole treatment improved acne in all women and reduced hirsutism in some, but it caused several side effects and requires careful monitoring.

In this case study, clomiphene citrate therapy restored hormonal balance and improved symptoms in a young male runner with hypogonadotropic hypogonadism related to endurance exercise.

Testosterone replacement therapy can prevent men from fathering children and should not be used by those wanting to stay fertile.

This study found that GLI2 plays a key role in activating follistatin, an activin/BMP antagonist, in response to hedgehog signaling in human epidermal cells, with implications for hair follicle development and basal cell carcinoma.

The document concludes that identifying the cause of amenorrhea is crucial for proper treatment.

This study found that intravaginal testosterone significantly improved sexual satisfaction and reduced dyspareunia in postmenopausal women using aromatase inhibitors, with no effect on urinary incontinence.

This case report describes a male patient with aromatase deficiency, revealing that a c.628G>A mutation can lead to varied clinical features, such as low bone mass and normal metabolic profiles.

This study found that in mink, the pituitary gland is essential for normal seasonal pelage cycles, and manipulating hormone levels can affect hair growth and type.

Amenorrhea is when a woman doesn't have periods, with primary amenorrhea starting by age 15 or within five years of breast development, and secondary amenorrhea when periods stop for three months. It affects 3-4% of women not pregnant, breastfeeding, or in menopause, mainly due to polycystic ovary syndrome, hypothalamic amenorrhea, hyperprolactinemia, and ovarian failure.

This study found that lowering serum DHT levels with 5 mg finasteride daily did not significantly alter serum gonadotropin levels in healthy young men after 28 days.

This study found that combining Flutamide and an LHRH agonist in adult male rats effectively inhibited prostatic growth and reduced androgen-sensitive prostatic activity markers to levels similar to castrated rats.

This study suggests that many men with premature balding exhibit a hormonal pattern similar to some aspects of polycystic ovary syndrome in women.

This review examines menopause's endocrinology, treatment history, and associated changes, noting key issues for midwife management but reports no new clinical results.

This study found that increased serum A4A levels were associated with more severe polycystic ovary syndrome phenotypes and could be a useful marker for biochemical hyperandrogenemia.

This study found that L-type channel blockers can induce hair growth in Timothy syndrome by overcoming delays in anagen phase, suggesting a potential therapeutic role for tissue regeneration.

This article reviews the effect of aging on male hormone levels and fertility, highlighting the need for more research on the benefits and risks of androgen supplementation in older men.

This study reported that both drospirenone and chlormadinone acetate oral contraceptives had similar beneficial effects on clinical, metabolic, and hormonal parameters in women with polycystic ovary syndrome over six months.

In this study, decreased levels of SHBG and a high free androgen index were observed in men with severe premature baldness compared to controls, but this condition was not equivalent to PCOS or metabolic syndrome in females.
