PATHOLOGY

Detailed explanation-1: -Ejaculated sperm remain viable for several days within the female reproductive tract. Fertilization is possible as long as the sperm remain alive-up to five days. Sperm can also be preserved for decades when semen is frozen.

Detailed explanation-2: -Sperm survival and the fertile window Did you know there are only a small number of days in any cycle when you’re fertile? After ovulation, an egg cell can only survive for about 12-24 hours. Since sperm can live for up to five days in the female body, this means the fertile window is six days long in total.

Detailed explanation-3: -Sperm can survive for up to five days in sperm-friendly cervical mucus. Cervical mucus around the time of ovulation helps protect the sperm and keeps it alive, plus it makes it easier for the sperm to reach the egg, should it be present.

Detailed explanation-4: -The first sperm enter the tubes minutes after ejaculation. The first sperm, however, are likely not the fertilizing sperm. Motile sperm can survive in the female reproductive tract for up to 5 days.
