Sperm: 15 crazy things you should know
Hey Summer! This is an incredible feat compared to the brief lifespan of a mere few hours when there is no cervical fluid present. - Ejaculated sperm remain viable for several days within a woman's reproductive tract or in nutritive liquid culture medium in a lab setting.
How Long Can Sperm Survive After Ejaculation?
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. If they can make it past the uterus into the fallopian tubes using fertile cervical fluid channels, they can live there, waiting for the release of an egg. On average, each time a man ejaculates he releases nearly million sperm but it takes just one sperm to fertilise a woman's egg.
