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.
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 theyâve made it all the way to the fallopian tubes, where fertilization takes place. (A womanâs 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 doesnât get at all close to her vagina.
