How long can sperm live inside a man's body?

Answer 1

It takes 2-3 months (about 74 days) for sperm to mature. Mature sperm gather in the center of the tubules, while the immature sperm remain on the outer edges of the tubules. The nurse cells continuously "sweep" sperm into the center as they mature. When the sperm mature, they leave the tubules and enter the epididymis, a coiled, tubular organ attached to the testes. Here, the mature sperm learn to "swim" and fine-tune their motility (movement). Mature sperm resemble microscopic tadpoles. They have an enzyme-coated head, a tail, and a thinner portion of the tail, called an end piece. 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. What happens to the sperm if no ejaculation takes place? They die and are reabsorbed by the body. This is as close as a man comes to having a "period."
