Fever can lead to morphologic changes in sperm which decrease production and longevity. These effects can last for several weeks after the fever and may be dependent on how long the fever existed. Sperm do not live long without moisture. Sperm account for between two and five percent of the composition of semen. The semen provides a moist, nutrient rich environment for sperm according to News Medical. Once outside the body, the sperm will only live until the semen dries. Web MD states that semen can live longer inside water such as a bathtub or pool than on a dry surface, but the likelihood of the sperm finding its way into a woman's body from a pool of water is slim.

Sperm can live inside a woman's cervix or upper genital tract for up to seven days after ejaculation according to the American Pregnancy Association. As long as the sperm remains alive there is a chance for pregnancy.

I was just wondering if you could tell me how long semen can survive outside of the human body. My girlfriend is worried as some semen got on her hand and about 10 minutes later she touched her vagina. There was no intercourse and no genital contact. She missed her Pill so we were playing it safe.

Answers from Landon Trost, M.D. The life span of sperm after ejaculation depends on the circumstances. Ejaculated sperm remain viable for several days within a woman's reproductive tract or in nutritive liquid (culture medium) in a lab setting. Fertilization is possible as long as the sperm remain alive — at least five days. Sperm also can be preserved for years when semen is frozen.

Inside a woman’s body, sperm can live much longer than they can outside of the body. That is because a woman’s body is just the right environment for sperm! Inside the cervix, fallopian tubes, and uterus, sperm can live for up to as long as five days. However, most sperm will die within one or two days even if they are inside of the uterus. Sperm that are inside the vagina will usually die within a few hours.

When To Have Sex. Since sperm can live in a woman’s body for up to five days, and the egg can only live for 12-24 hours, it makes sense to have the sperm “ready and waiting” when the egg is released, if a couple is trying to get pregnant.

Under ideal circumstances, if healthy sperm get beyond the cervix into the uterus and up to the fallopian tubes, they can live as long as 5-7 days after ejaculation. On average, though, sperm live about 3-4 days once they’ve made it all the way to the fallopian tubes, where fertilization takes place. (A woman’s egg, on the other hand, is viable for only about one day once it leaves the ovary.) Sperm can live outside of the body for only about 20 minutes to an hour, depending on how exposed the semen is to the air and other environmental factors. To avoid the slightest risk of pregnancy, a woman should make sure that ejaculated semen doesn’t get at all close to her vagina.
