Dihydrotestosterone has been implicated in muscle growth through its role in promoting protein synthesis, particularly in muscles and reproductive organs. Dihydrotestosterone can be produced directly by the testes or by peripheral tissues that convert androgens and estrogens as precursor substances, and belongs to the androgen class. The effects of dihydrotestosterone in the body mainly include maintaining normal sperm production; promoting the development of male reproductive organs and the emergence of secondary sexual characteristics; maintaining normal libido; promoting protein synthesis, especially protein synthesis of muscles and reproductive organs; promoting bone growth and regulating calcium and phosphorus metabolism, and so on. Dihydrotestosterone can be used clinically to assist in the diagnosis or differential diagnosis of benign prostatic hyperplasia, prostate tumors, infertility, hirsutism and other diseases.
