GlossarySteroid 5 Alpha-Reductase 2 (SRD5A2)

enzyme converting testosterone to potent androgen dihydrotestosterone (DHT)

Steroid 5 Alpha-Reductase 2 (also known as 5α-Reductase Type 2 or SRD5A2) is an enzyme that converts testosterone into dihydrotestosterone (DHT), a more potent androgen. This enzyme plays a crucial role in the development of male characteristics and is also implicated in conditions like male pattern baldness and benign prostatic hyperplasia.
