Sperm is produced from the testes, and after developing and maturing in the epididymis, it passes through the vas deferens, seminal vesicles for storage, and then through the action of enzymes such as prostatic proteolytic enzyme and fibrinase, which ultimately liquefy the sperm. The normal quantity and quality of sperm will usually return to normal within 3 days.
