whats the living time
Once inside the fallopian tube, the sperms have a life span of about 5 days.
This means they can be in the fallopian tube for 5 days in advance of ovulation and still fertilize the egg.
How long sperm can live in the open-air depends on the situation, what kind of environment it's in and how much sperm is present. But, on average, sperm can't live for much longer than a few hours in the open-air.
