The combination of male sperm and female eggs is necessary for a woman to conceive. Normally, mature males can produce tens of millions of sperm at once, but most of these sperm lose their vitality and die due to the acidic environment of the female reproductive tract. This is also one of the reasons for infertility. Many people may ask about this, how long does sperm survive in women's bodies?
Generally speaking, the lifespan of sperm in women does not exceed 8 hours. Then only a small portion of the sperm will escape and continue to move forward. Why is this? Because the sperm in the semen during sexual intercourse can be protected by a large amount of fructose and enzymes that break down sugars in the semen. However, when the sperm enters the uterine cavity and leaves the semen, the living conditions are far inferior to those in the semen, resulting in a greatly shortened lifespan. Inferior quality semen runs slowly and cannot reach the uterine cavity quickly, thus losing its vitality.
So, how long does sperm survive in a woman's body after entering it? Experts say that after passing through various checkpoints, there are very few sperm left that can ultimately reach the fertilized site of the fallopian tubes. However, as long as sperm enter the fallopian tube, they have strong fertilization ability. Of course, only 1-2 sperm were fortunate enough to combine with the egg, while the remaining sperm died within 24-36 hours. Only sperm stored in the crypt of the cervical mucosa have a lifespan of 2-6 days. However, their ability to fertilize has been basically lost, as most sperm can only maintain fertilization for about 20 hours.
The egg has the strongest fertilization ability within 15-18 hours after being discharged from the ovary, and can maintain fertilization ability for about 30 hours. Afterwards, the egg begins to degenerate, and fertilization ability rapidly weakens and disappears.
Although sperm injected into the female reproductive tract can survive for up to 4-5 days, it has strong fertilization ability for 1-2 days, which means that pregnancy is only possible within 1-2 days before and after ovulation. This is very important for guiding infertile couples in their sexual life. Some couples have no issues with their reproductive function, but due to neglecting the timing of conception, they become infertile for several years after marriage.
