The bark of Myrica rubra contains compounds that can block testosterone effects and might help prevent hair loss.

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.

Spironolactone reduces the enzyme activity that converts testosterone to DHT, helping treat excessive hair growth in women.

Testosterone helps beard and axillary hair cells grow by releasing growth factors from dermal papilla cells.

Human skin produces sex hormones like estrogen and testosterone, influenced by ARO and StAR, which may affect skin elasticity and hair growth.

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.

Testosterone causes hair loss in AGA mice, which are good for testing baldness treatments, and both minoxidil and cyproterone acetate can prevent this 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.

Hormone therapy affects hair growth in transgender individuals, with testosterone potentially causing hair loss in trans men and estrogen reducing facial/body hair in trans women; treatment options vary.

Testosterone therapy and surgeries like mastectomy improve transgender men's lives and mental health with low risks and high satisfaction.

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.
