NOT AT ALL !!!!! Fertile sperm are at the endpoint of an elaborate pathway that starts from stem cells and generates waves of new sperm continuously. Once they finish formation they contain the proper energy stores & genetic material to survive about 5-6 days at most after which the energy stores are gone & they are inactivated. Unwanted pregnancy occurs from intercourse without birth control.

Agree with Dr. F. Sperm is not viable beyond a few days, in the female genital tract. It is not useful after a day or so outside the body.
