Whether you are sexually active or not, you, and thousands of others, have all wondered the same thing: how long does sperm live outside the body. This article will provide you with the answer, as well as some interesting facts that you may also need to know.
The first thing you need to know is that the lifespan of sperm outside of a man’s body varies. The main reason for this is due to the environment that the sperm is in post ejaculation. In fact, some sperm are dead by the time they leave a man in the first place.
There are many different environments sperm can live in after ejaculation, and the most common are probably inside of a sexual partner’s mouth, vagina, or anus, in a condom, or on clothing or bed sheets.
Sperm will generally have the longest lifespan in a moist and protective environment, such as a woman’s vagina. Inside of a woman’s reproductive organs, sperm can live anywhere from a couple minutes or up to three days. This long lifespan gives sperm a chance to find an egg and fertilize it, otherwise it would be very difficult to conceive a child.
If a man ejaculates inside of another human orifice, such as an anus, his sperms lifespan may be as long as 72 hours as well, but it isn’t as likely due to the fact that it is where fecal matter resides. Sperm will also have a shorter lifespan inside of a mouth or stomach due to digestive enzymes and stomach acid killing off the sperm.
Any other surface that sperm might reside on outside of the human body is generally dry and inhospitable. The longest sperm will live, on say, a bed sheet, will be no longer than a couple hours. The strongest swimmers will survive the longest, but they will be so far and few in between that even if it gets into the vagina, it is unlikely she will get pregnant.
