This study found that nafarelin treatment significantly reduced androgen levels and improved hirsutism symptoms in women, suggesting it may be useful for managing this condition.

This study found that a nomogram prediction model based on clinical characteristics, bone metabolism, and ovarian function can effectively predict the treatment response to long-acting GnRHa in girls with idiopathic central precocious puberty.

In this study, significant elevations of DHA and testosterone were associated with pubic hair development and voice changes in boys during puberty.

This study found that women with polycystic ovary syndrome have more pronounced metabolic alterations and higher androgen levels compared to women with eumenorrheic hyperandrogenism, suggesting EuHyperA may be a milder form of PCOS.

This review discusses therapeutic options for pubertal induction in congenital hypogonadotropic hypogonadism, focusing on recombinant gonadotropins, and highlights the need for larger randomized trials to determine optimal treatment strategies.

In this study, patients with alopecia areata had significantly higher levels of luteinizing hormone and follicle-stimulating hormone compared to healthy controls, suggesting a link between hormone levels and the disease.

This study found that oral contraceptives effectively suppressed hyperandrogenemia in most patients with hyperandrogenic-insulin-resistant acanthosis nigricans syndrome, though GnRH-a therapy was beneficial for those not responding initially.

This study reported that ketoconazole may effectively normalize menstruation and reduce testosterone and hair growth in women with ovarian hyperandrogenism, though its safety needs further evaluation.

This study found that, among fertile egg donors, the AR gene CAG polymorphism was associated with differences in antral follicle count but did not impact ovarian response to gonadotrophins.

This study reports that a young man with severe testotoxicosis maintained spontaneous fertility despite suppressed FSH levels, underscoring the importance of high intratesticular testosterone levels for spermatogenesis.

This article reviews differential diagnosis approaches for 46,XY DSD, proposing a diagnostic algorithm focused on biochemical and genetic data, without presenting new clinical results.

This article discusses the hypothalamus-pituitary-testis axis in androgen production and spermatogenesis but presents no new research findings.

A 19-year-old male with delayed puberty was successfully treated for a condition that prevents normal hormone production.

In this study, subclinical hypothyroidism in women with PCOS was linked to changes in the thyroid-prolactin axis and a lack of correlation between TSH and AMH, while gonadotropin levels and ovarian morphology remained unaffected, indicating the need for further prospective research.

This case study of a subfertile couple highlighted the importance of considering haemochromatosis, particularly involving the C282Y mutation of the HFE gene, in patients with endocrine disorders linked to hypogonadism.

This study found that male volunteers with baldness had significantly decreased levels of gonadotropin hormones LH and FSH compared to healthy men, suggesting potential treatment targets for androgenetic alopecia.

This study observed a significant decrease in gonadotropins (LH and FSH) among men with androgenetic alopecia, suggesting their potential role as treatment targets for male baldness.

This review discusses hormonal therapies for acne related to endocrine disorders and provides practical guidelines for managing hormonally influenced acne in clinical practice, but reports no new clinical results.

Finasteride may decrease semen quality but not harm sperm production, and stopping the drug can improve semen quality; hyperprolactinemia can cause infertility but is treatable with medication.

This case study reports that in an 8-year-old male, a pituitary adenoma causing isolated high LH secretion led to early testosterone-driven puberty without typical testicular enlargement, highlighting the differential roles of LH and FSH in pubertal development.

This study suggests that metformin has a stronger impact on gonadotroph hormone levels in men with early-onset androgenic alopecia compared to those with normal hair growth.

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.

Lifestyle changes and medical treatments can help manage infertility in women with PCOS.

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.

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.

In this case report, an embryonal cell carcinoma of the testicle was associated with polycythemia and markedly elevated hormone levels without secondary sexual characteristics, which were restored after treatment.

This letter discusses alopecia universalis and Kallman’s Syndrome, and offers no new clinical results.

This case study observed that in four middle-aged men with ejaculation disorders, therapy with human chorionic gonadotropin (hCG) alone or combined with recombinant follicle-stimulating hormone (rFSH) improved sexual desire, semen volume, and various other symptoms, although some experienced elevated estradiol levels and hair loss.

In this study, women with a complete hydatidiform mole had significantly higher pre-evacuation levels of hCG, free testosterone, and DHEA-S compared to controls, which declined after HM evacuation.

This chapter reviews the biology and biochemistry of hormones involved in male sexual development and physiology, without reporting new research findings.
