Sperm usually survive in the female body for about 24 hours, and in rare cases, some sperm can survive for about 72 hours. After a couple has intercourse, the sperm enters the vagina and travels through the cervix into the uterine cavity, where it later meets the egg in the middle and upper part of the fallopian tube and turns into a fertilized egg. The survival time of sperm in a woman’s body is usually around 24 hours. However, in a few people, some of the sperm are particularly strong in terms of vigor and quality and can survive for up to 72 hours or so. In order to increase the conception rate, couples who plan to have a baby can try to accurately grasp the time of ovulation by calculating the ovulation period and monitoring it with ovulation test strips, etc. Having intercourse during ovulation will help to increase the conception rate. For couples who are preparing for pregnancy, a healthy lifestyle can also help improve the quality of sperm and eggs, which is conducive to conception.
