Does Sperm Die As Soon As It Hits The Air?
  • If kept warm at body temperature (like on the skin or in a warm test tube), sperm remain motile for several hours. Inside the female reproductive tract, they can live for up to 3-7 days. Sperm are very sensitive to temperature and moisture and will eventually die outside the body, but since each ejaculate may contain as many as 750 million sperm, and it only takes one sperm to result in pregnancy, precautions are essential. Ejaculation anywhere near the vagina, without condom use, should be a reason to consider emergency contraception.

No. It's a little more complex than a simple "no." Sperm can live for about a week if they have the nourishment they find when they are inside a man or a woman. Air does not kill sperm, but without the moist, warm environment of the body, sperm usually die anywhere from 30 minutes to as much as four hours. Interestingly enough, they have recently shown that sperm that has been air dried and then rehydrated four weeks later could actually fertilize an egg. The bottom line is that if one is trying to prevent pregnancy and is participating in sexual activity that involves ejaculation outside of the body, good handwashing needs to be practiced. Hope this helps! Dr. B.

No, sperm can live outside the body on a surface for about a hour and even longer in the vagina.
