Prostate is the largest accessory gonad of human body and one of the exocrine glands of human body. Prostate fluid is an important part of semen, which plays an important role in the normal function of sperm and is very important for sperm reproduction. The secretion of prostatic fluid is regulated by androgen. Prostate is rich in 5α reductase, which can convert testosterone into dihydrotestosterone with stronger physiological activity. Dihydro testosterone plays an important role in the pathogenesis of benign prostatic hyperplasia. Blocking 5α reductase can reduce the production of dihydrotestosterone and shrink the benign prostate tissue.
