Here's how long sperm actually lasts for after sex | gadicaplan.com
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.
The length of time they stay alive has a lot to do with environmental factors and how fast they dry up. If you ovulate shortly after you finish your period, the sperm may still be alive and can fertilize the egg. Learn more: Can you get pregnant if you have sex on your period?
