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.
Then the sperm travels to be stored in the epidydimus, which is a large, coiled-up tube outside the testicles, but still inside the scrotum (sac). This 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.his is where they are stored until needed.
