Sperm can be stored inside the male body for approximately 3 weeks after they've matured, after which they die inside the body if not ejaculated. So the entire sperm life cycle inside a man's body if not ejaculated (10 week maturation time + 3 week storage lifespan) is approximately 13 weeks or about 3 months.
The male reproductive organs include the testes, the epididymis, the vas deferens, seminal vesicles, prostate, bulbourethral glands, scrotum and penis.Nearby structures are the bladder and rectum. Sperm are produced in the testes and move into the epididymis where they mature over a period of 10 to 14 days.Sperm are stored here and in the vas deferens where they can remain viable for several months.earby structures are the bladder and rectum.
