A potent androgen formed from testosterone in tissues such as skin and hair follicles.

Why it matters for PCOS

DHT (dihydrotestosterone) is an androgen stronger than testosterone. It is formed when the enzyme 5-alpha-reductase converts testosterone within local tissues, especially the skin and hair follicles. Because its effect happens at the tissue level, DHT is linked to the skin and hair symptoms of PCOS, including acne, oily skin, excess facial hair (hirsutism), and scalp hair thinning in women whose follicles are sensitive to androgens.

DHT is rarely measured routinely in PCOS blood tests, since doctors usually check testosterone instead. Some medicines that block androgen effects are prescription-only and need to be monitored by a doctor.

FAQ

Frequently Asked Questions

What is Dihydrotestosterone (DHT)?

DHT is an androgen stronger than testosterone, formed when the enzyme 5-alpha-reductase converts testosterone within tissues such as skin and hair follicles.

How does DHT relate to PCOS?

The sensitivity of hair follicles to DHT can contribute to acne, oily skin, excess facial hair, or scalp hair thinning in some women with PCOS.

Is DHT measured in PCOS blood tests?

Usually not. Doctors typically measure testosterone rather than DHT routinely, because DHT's effect depends on enzyme activity in local tissues.
