This study found that lean women with PCOS have a similar degree of tissue insulin resistance as obese women with PCOS, suggesting that insulin resistance may be a primary feature of the syndrome.

This study found that prenatal antiandrogen treatment in female spotted hyenas significantly altered the LH response to GnRH, indicating partial masculinization of their anterior pituitary gland without affecting ovulatory function.

This study found that metformin treatment during pregnancy in women with PCOS was associated with higher SHBG levels in newborns, but did not affect androgen or estrogen levels at birth.

This study found that in dogs with alopecia, certain steroid hormone levels were elevated, particularly progesterone, but not all hormone abnormalities were consistent across breeds, suggesting the need for breed-specific evaluation.

This study found that among women above 15 years with acne, 54.56% exhibited hyperandrogenism, with dehydroepiandrosterone sulfate levels most frequently elevated.

In this study, two different estroprogestin treatments significantly improved skin conditions and decreased androgen levels in hyperandrogenic women, with EE/DRSP showing more pronounced hormonal changes and skin improvements compared to EE/CMA.

This article reviews the role of 5α-reductase in cutaneous hyperandrogenism and the potential of 5α-reductase inhibitors and antiandrogens in treating conditions like hirsutism and male-pattern baldness, reporting no clinical results.

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

This study observed that flutamide treatment reduced hair growth and improved acne and seborrhea in hirsute women, with increased androstenedione levels and no side effects noted.

This report describes two cases of alopecia in neutered female ferrets linked to neoplastic tissue at the site of an ovarian pedicle, suggesting an ovarian origin for the tumors.

This study found that one year of antiandrogen treatment with spironolactone significantly decreased bone mineral density in young women with androgen excess.

This study found that local androgen biosynthesis and metabolism in human sebaceous glands play a crucial role in sebum synthesis and secretion.

This study observed that testosterone metabolism and androgen receptor localization differ significantly across body sites, with beard hair follicles showing distinct characteristics compared to occipital scalp hair follicles.

In this study, men taking 1 mg/day of finasteride for 12 months showed minor metabolic changes and slight improvements in glucose metabolism.

Women's ovarian hormones and adrenal androgens change throughout life, affecting hair loss and health.

This study suggests that in women with androgenic alopecia and men with premature balding, enhanced 5α-reductase activity and altered androgen conjugation, favoring sulfurylation, may be involved in scalp hair loss.

This study found significant hormonal differences, including elevated cortisol and androstenedione levels, in both male and female androgenic hair loss patients compared to controls, suggesting complex hormonal interactions in the condition.

This study reports that oophorectomy significantly reduces serum testosterone levels in postmenopausal women, indicating the postmenopausal ovary's continued production of testosterone.

This meta-analysis confirmed associations between some androgenic and metabolic parameters in women with PCOS, suggesting that these measurements might help predict metabolic risk in this population.

This study found that male pattern hair loss may be associated with differences in serum levels of androstenedione, cortisol, 17 beta-estradiol, and luteinizing hormone, compared to controls.

In this study, treatment with flutamide combined with a low-dose oral contraceptive significantly improved hirsutism in women with polycystic ovarian disease who did not respond to oral contraceptive treatment alone.

This study found a high prevalence of hyperandrogenemia in women with PCOS, with distinct biochemical differences according to BMI and presence of hyperandrogenemia.

This study suggests that alterations in copper metabolism may play a key role in the development of androgenetic alopecia in women, presenting potential targets for treatment strategies.

In this study of hirsute women, researchers found that correlations between hirsutism and hyperandrogenism were observed only in patients with a low LH/FSH ratio.

This case study reports that hormonal imbalances in a young boy with precocious pseudopuberty returned to normal after the removal of a testicular interstitial cell tumor, with normal spontaneous puberty following.

This review discusses ovarian hyperthecosis as a rare cause of androgenetic alopecia in postmenopausal women and reports no new results; the authors highlight the need to explore its relationship to alopecia further.

This review discusses the challenges in measuring testosterone for assessing androgen excess in women and emphasizes the importance of quality control in laboratory methods, but it reports no new clinical results.

In this study, women with androgenic alopecia showed increased excretion of steroid metabolites and heightened 5α-reductase activity, suggesting these may contribute to the condition's hormonal abnormalities.

This study found that both cyproterone acetate alone and combined with ethinyl oestradiol reduced androgen levels and slightly increased SHBG binding in women with hirsutism, but showed no difference in hair regrowth rate between the treatments.

In this study, oral cyproterone acetate reduced hair density and diameter in women with idiopathic hirsutism, but the effects were not permanent after stopping treatment, and plasma androgen levels remained unchanged.
