How long can a man's sperm survive inside a woman's body?

Only when sperm and egg combine can a fertilized egg be formed. Therefore, if you have sex before you are ready for pregnancy, you must take appropriate contraceptive measures. When a couple who are not prepared for pregnancy have sex, they should try not to let the male's sperm enter the female's body, because this will greatly increase the chances of pregnancy. So how long can a man's sperm survive in a woman's body?

Experts say: Sperm can survive longer in a woman's body than an egg, generally 2-3 days, and even longer in some cases. Studies have shown that human sperm can only survive for a few minutes in the natural environment outside the body. After sperm pass through various checkpoints, only a few sperm can finally reach the fertilization site in the fallopian tube. However, as long as the sperm enters the fallopian tube, it has a strong fertilization ability. Of course, in the end only 1-2 sperms are lucky enough to combine with the egg, and the rest of the sperms will die within 24-36 hours. Only the sperm stored in the crypts of the cervical mucosa can live up to 2-6 days. Even so, its fertilization ability has been basically lost because the fertilization ability of sperm can only last for about 20 hours.

Although sperm ejaculated by men into the female reproductive tract can survive for up to 4 to 5 days, their strong fertilization ability lasts only 1 to 2 days. That is to say, conception is only possible if sexual intercourse occurs within 1 to 2 days before or after a woman's ovulation. This is very important for guiding the sexual life of infertile couples. Some couples have no problem with their reproductive function, but they remain infertile for several years after marriage because they ignore the opportunity to conceive. Therefore, if you are a woman who does not want to get pregnant for the time being, it is best to allow a few extra days when calculating the ovulation period and the dangerous period, and it is also best to take precautions three days before the ovulation period. Of course, for those who are planning to get pregnant, they can also act in advance to increase their chances.

The above is an introduction to how long a man's sperm can survive in a woman's body. In short, after you have sex, it is very necessary to know how long a man's sperm can survive in a woman's body. Because only if you correctly grasp the survival time of sperm can you better control the contraceptive method and the time of conception.
