Life long sperm

The length of time they stay alive has a lot to do with environmental factors and how fast they dry up.

Facts about sperm health and lifespan

In recent years, large volumes of evidence have supported the hypothesis that as males age their sperm is affected in ways that can lead to less viable offspring. Yet, as research gets more granular and takes a closer look at the sperm cells themselves, new information crops up—exactly what a team of investigators at the University of East Anglia UEA and Uppsala University in Sweden discovered. The researchers found that sperm who live for longer before fertilizing an egg produce healthier offspring. The new study shows that longer-lived sperm in an ejaculate of a zebrafish male produces offspring with longer and healthier lifespans—who in turn produce more and healthier offspring themselves—than the shorter-lived sperm in the same ejaculate.

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.
