Dihydrotestosterone has a reduced effect on muscle-building in people with testicular feminization syndrome, especially after their gonads are removed.
research Female androgenic alopecia. The 3 alpha,17 beta-androstanediol glucuronide/sex hormone binding globulin ratio as a possible marker for female pattern baldness
Women with more 3α,17β-androstanediol glucuronide compared to sex hormone binding globulin are more likely to have female pattern baldness.
research 4 Anti-androgens in gynaecological practice
Cyproterone acetate is effective for treating hirsutism and acne in women by blocking androgens in the skin and also works as a contraceptive.
research In Silico Screening of DrugBank Compounds as Potential Inhibitors for Human Steroid 5α-Reductase 2 for Androgen-Related Diseases
Stiripentol shows promise as a potential treatment for androgen-related diseases but needs more testing.
research Prostate-Sparing Effects in Primates of the Potent Androgen 7α-Methyl-19-Nortestosterone: A Potential Alternative to Testosterone for Androgen Replacement and Male Contraception1
MENT could be a better option than testosterone for male hormone therapy and birth control because it works well at lower doses and has fewer side effects on the prostate.
research Exploring the mechanism of stigmasterol against androgenetic alopecia using geometry optimization, network pharmacology, molecular docking, and molecular dynamics studies
Stigmasterol may help treat hair loss, but more research is needed.
research The influence of obesity on Androstenedione to Testosterone ratio in women with polycystic ovary syndrome (PCOS) and hyperandrogenemia
Obesity changes androgen levels in women with PCOS, leading to higher testosterone relative to androstenedione.
