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.
So it is possible for some sperm to survive that long in the uterus, usually in the cervical mucus or the fallopian tubes. But that is not typical. Most sperm die in the uterus within 24-48 hours after ejaculation, and the more time has passed after ejaculation, the less likely is the fertilization of the egg. In excellent laboratory conditions and in a nutrient medium they can remain alive for up to seven days.
