After ejaculation, sperm can live inside the female body for around 5 days. The fluid in a woman's reproductive tract has all of the nutrients that sperm need for their survival during that time.
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. Mayo Clinic does not endorse companies or products.
An important aspect of fertility and pregnancy is sperm, and the lifespan of sperm after ejaculation completely depends on where it's living. How long sperm live depends on where the sperm are deposited.

This is where the six-day fertile window comes from, as sex in the five days leading up to ovulation, or on the day of ovulation, can lead to conception.
Sperm can live outside the body for varying amounts of time, depending on several factors, including the environment Ie: cervical mucus, where they end up… 9. Inside the vagina. This is an incredible feat compared to the brief lifespan of a mere few hours when no cervical mucus is present 24.
