Testosterone and dihydrotestosterone affect hair growth, and new techniques like the folliculogram help study it, but fully understanding hair growth is still complex.

Testosterone therapy is generally safe for transmen, improves sexual function, and has manageable health risks with proper monitoring.

Longer CAG repeat lengths in the androgen receptor gene are linked to higher testosterone levels in women with PCOS.

Finger length ratios are not linked to the number of specific gene repeats affecting testosterone sensitivity.

Young women with diffuse hair loss may have low SHBG levels, which could lead to more active testosterone and contribute to their hair loss.

Androgens like testosterone are important hormones for both men and women, made differently in each sex and affecting the body by regulating genes and quick interactions with cell components.

Epitestosterone may act as a weak antiandrogen and can inhibit an enzyme involved in testosterone metabolism.

Insulin-sensitizing drugs like metformin can help with ovulation, weight loss, and lower testosterone in some women with PCOS.

Some antiandrogens may lower testosterone better than others, but it's unclear which is best for feminization in transgender women; more research is needed.

Human beard hair follicles change testosterone into other related hormones, but don't much change androstenedione into testosterone.

Testosterone is made by Leydig cells, is active when not bound to proteins, and works by binding to receptors in muscles and other tissues.

Testosterone therapy seems safe and effective for transgender men with proper care, but more long-term research is needed.

Testosterone and its byproducts help support male sexual behavior through different pathways in the brain and body.

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.

Testosterone treatment in transgender teens can worsen acne, requiring careful treatment due to mental health and medication side effects.

Certain SHBG gene variants, like rs727428, are linked to higher testosterone levels in women with PCOS.

The substance MK386 effectively blocked testosterone conversion and reduced cell growth in certain skin cells, but inhibiting 5α-reductase alone may not greatly improve acne.

Androgens, male hormones, play a role in both men and women's health, and testosterone therapy can help women with low levels, but it's not suitable for pregnant or lactating women, or those with certain conditions.

These drugs cause hair growth without affecting testosterone or adrenal hormones.

New and future treatments for male hypogonadism include various forms of testosterone therapy and emerging drugs.

Hormone therapy with estradiol and spironolactone can regrow scalp hair in transgender women by lowering testosterone to female levels.

Researchers found potential urine markers for polycystic ovary syndrome, including testosterone-glucuronide and 11α-hydroxyprogesterone, which may help diagnose the condition.

Oophorectomy lowers testosterone and estrogen levels in both premenopausal and postmenopausal women, with postmenopausal women still producing significant testosterone.

Most hirsutism cases are due to PCOS, and treatment focuses on lowering testosterone and blocking its effects.

Some new progesterone derivatives are better at blocking testosterone conversion than a common drug.

Finasteride reduces dihydrotestosterone, increases testosterone, and may treat hirsutism in women.
