research Use of Insulin-Sensitizing Agents in Patients With Polycystic Ovary Syndrome
Insulin-sensitizing drugs like metformin can help with ovulation, weight loss, and lower testosterone in some women with PCOS.
research A Systematic Review of Antiandrogens and Feminization in Transgender Women
Some antiandrogens may lower testosterone better than others, but it's unclear which is best for feminization in transgender women; more research is needed.
research Metabolism of Androgens by Isolated Human Beard Hair Follicles
Human beard hair follicles change testosterone into other related hormones, but don't much change androstenedione into testosterone.
research Androgens
Testosterone is made by Leydig cells, is active when not bound to proteins, and works by binding to receptors in muscles and other tissues.
research Hormone-Dependent Medial Preoptic, Lumbar Spinal Cord, and Autonomic Coordination Supporting Male Sexual Behaviors
Testosterone and its byproducts help support male sexual behavior through different pathways in the brain and body.
research Mechanism of Action of Androgen in Hair Follicles
Testosterone affects hair follicles differently across body sites, with beard hair follicles showing more activity of a specific enzyme and presence of androgen receptors compared to scalp hair.
