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.
Once inside the epididymis, mature sperm wait to be ejaculated into the vagina -- not unlike the scene depicted in Woody Allen's satirical film, Everything You Always Wanted to Know About Sex, where the sperm are waiting to parachute out of an aircraft and complete their mission.he sperm are produced inside these tubules, where they stay until they're mature. Sperm cells have their own guardians, the Sertoli cells, also known as nurse cells, which help protect and nourish the sperm until they're mature.
