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.
Making the world better, one answer at a time. Mature sperm cells are stored in the epididmysis, a long tube that is coiled up behind the testes in the scrotum.his is where they are stored until needed. As needed, the sperm cells travel through a pair of tiny tubes called the vas deferens (Hence the term,'vas-ectomy'). The sperm enter the stream of semen near the urethra, or urinary tube.
