5-alpha reductase

5-alpha reductase is an enzyme in the body that converts testosterone, the primary male hormone, into a more potent form called dihydrotestosterone (DHT). DHT plays a key role in the development of male characteristics such as facial hair, deep voice, and prostate growth. This enzyme is active in tissues like the skin, prostate, and hair follicles. Some medications target 5-alpha reductase to treat conditions like enlarged prostate or hair loss by reducing DHT levels, helping to manage symptoms associated with excessive DHT activity.
