Quick Summary

Dihydrotestosterone (DHT) is a potent androgen, a type of male sex hormone, that is a biologically active metabolite of testosterone. It is produced in various tissues, including the testes, prostate gland, hair follicles, and muscles, where it plays a crucial role in male development and characteristics.12

DHT is essential for the formation of external genitalia in boys during embryonic development and for sperm maturation during spermatogenesis. It is also responsible for sexual maturation at puberty and contributes to the development of secondary male characteristics such as facial hair and a deepening voice. While testosterone itself has androgenic effects, its conversion to DHT is critical for many of these processes.2
