The prostate produces a fluid which protects sperm in the vagina. It contributes about 30% to the volume of the ejaculate (semen), the seminal vesicles (the small glands located next to the prostate) contribute 60%, and sperm makes up the remaining 10%.
It converts testosterone to DHT (dihydrotestosterone).
Its contraction during orgasm contributes to sexual pleasure.
