However, the average sperm will live just 3-4 days even after making it to the fallopian tubes. Only the heartiest of sperm will get a chance at fertilizing the egg. While a spermâs lifespan lasts several days, a womanâs egg is only viable for one day after it is released.

So if the sperm has dried it is not going to get anyone pregnant. Experts have differing estimates on how long sperm can live outside the man's body.

But outside of the human body, sperm have a much shorter existence, from 20 minutes to an hour, depending on such factors as exposure to air and humidity.
