The good news, there are some very tangible lifestyle changes that men can make to improve their sperm health and overall fertility.

You also might not realize that when sperm are initially formed within the testicles, they lack the ability to swim forward or fertilize an egg until they make their way through the reproductive tract. Sperm are living cells within the male body and are subject to whatever conditions the rest of the body is exposed to throughout their development cycle.

A lot of numbers are thrown out there about the lifespan of sperm but here's the scoop: sperm can live as little as a couple of hours or as long as five days after sex. Once inside the vagina, the lifespan of the sperm depends on the woman's vagina, uterus, and fallopian tubes. Without fertile cervical fluid, sperm won't survive longer than a few hours inside the vagina or uterus if they make it that far. Many sperm die off in the very acidic vaginal canal within the first 12 hours.
