    Glossary 5α-reductase

    enzyme converting testosterone into potent dihydrotestosterone (DHT)

    5α-reductase is an enzyme that converts testosterone into dihydrotestosterone (DHT), a more potent androgen hormone. This enzyme plays a significant role in various biological processes, including the development of male characteristics and the regulation of hair growth. Inhibitors of 5α-reductase, such as finasteride, are commonly used to treat conditions like male pattern baldness and benign prostatic hyperplasia.
