research Recommendations for treatment of nonclassic congenital adrenal hyperplasia (NCCAH): An update
The document suggests treating individuals with nonclassic congenital adrenal hyperplasia who show symptoms, especially those related to excess male hormones.
research Allopregnanolone promotes proliferation and differential gene expression in human glioblastoma cells
Allopregnanolone increases growth and changes gene activity in human brain cancer cells.

Women with excessive hair growth or polycystic ovary disease may more often carry a gene variant for 21 hydroxylase deficiency.
research Invalidation of a commercially available human 5α-dihydrotestosterone immunoassay
The DHT immunoassay is unreliable due to high cross-reactivity with testosterone.
research Characteristics of flutamide action on prostatic and testicular functions in the rat
Flutamide combined with an LHRH agonist effectively inhibits prostate growth, suggesting it could treat prostate cancer.
research Vitamin D Status and the Effect of Oral Vitamin D Treatment in Children with Alopecia Areata
Oral vitamin D treatment can help some children with alopecia areata who have vitamin D deficiency.
research Cellular actions of testosterone in vascular cells: Mechanism independent of aromatization to estradiol
Testosterone affects vascular cells directly without converting to estradiol.
research Androgen treatment of postmenopausal women
Testosterone therapy can improve sexual desire and function in postmenopausal women but should be used cautiously and not based solely on testosterone levels.
research Role of 5α-dihydrotestosterone in testicular development of gilthead seabream following finasteride administration
DHT affects testicular development and regulates spermatogenesis in some fish.
research Effects of the 5α-Reductase Inhibitor Finasteride on Serum Levels of Gonadal, Adrenal, and Hypophyseal Hormones and its Clinical Significance: A Prospective Clinical Study
Finasteride reduces hair loss and treats BPH without major hormone changes, but may cause sexual dysfunction.
research The effect of spironolactone on genital skin 5α-reductase activity
Spironolactone reduces the enzyme activity that converts testosterone to DHT, helping treat excessive hair growth in women.
research Gene expression of type 2 17β hydroxysteroid dehydrogenase in scalp hairs of hirsute women
Hirsute women have lower type 2 17β-HSD enzyme levels, which improve with treatment.
research The differences between aromatizable and non-aromatizable androgens in relation to body composition and metabolic syndrome risk factors in men
Testosterone and dihydrotestosterone have similar effects on body composition and metabolic health in men.
research Polycystic Ovarian Morphology is Associated with Hyperandrogenemia and Insulin Resistance in Women with Polycystic Ovary Syndrome (PCOS)
Women with PCOS and polycystic ovaries have higher male hormone levels and more insulin resistance, especially if they are overweight.
research A comparative study of Aldactone® and Diane® in the treatment of hirsutism
Aldactone was more effective in reducing hair growth in women with hirsutism than Diane, despite having less impact on hormone levels.
research The therapeutic use of androgens in women
Testosterone replacement may improve sexual desire and bone health in women with low androgen levels, but more research is needed on its long-term safety.
research The clinical development of a 5α-reductase inhibitor, finasteride
Finasteride effectively treats BPH, but needs more trials to understand potential.
research Overexpression of aldo-keto reductase 1C3 (AKR1C3) in LNCaP cells diverts androgen metabolism towards testosterone resulting in resistance to the 5α-reductase inhibitor finasteride
Too much AKR1C3 enzyme causes resistance to finasteride by increasing testosterone.
