benign prostatic hyperplasia(BPH) pathogenesis(5α-redactase convert testosterone into dihydrotestosterone,DHT)
after 30yo,testosterone production decline by 1% every year
meanwhile,5α-redactase increase with age
eventually, more DHT allows luminal and basal cells in the prostate to keep growing and multiplying urologyreproductive May 11, 2019, 1:30 AM HirotoShishido
