How long does semen survive?

Every male will have mature sperm discharged from his body every day after he reaches adulthood. Mature sperm can help women get pregnant. However, many men often suffer from diseases such as azoospermia or sperm cannot survive for too long, which has a great impact on the male body. So how long is the survival time of sperm? How to identify the survival time of sperm.

Sperm can survive in a woman's body for about eight days because some sperm enter the folds of the cervix. In the middle of a woman's menstrual period, the mucus on the surface of the cervix encourages sperm to enter the folds. At the beginning of ovulation, the cervix opens a little and the mucus layer changes, allowing sperm to swim forward into the uterus.

A test of cervical mucus taken 48 hours after intercourse showed the presence of many live, healthy sperm, just as there were immediately after intercourse. It is currently believed that sperm gradually leave the cervical area; some enter the uterus immediately after ejaculation, while others wait longer in the cervical folds, allowing sperm to ascend to the uterus in small groups, increasing the chances of sperm meeting the egg.

The junction of the two fallopian tubes and the uterus is also where sperm resides. Perhaps only a small number of sperm are allowed to pass through the fallopian tubes at a time, which again proves that sperm spends a long time entering the fallopian tubes in batches, increasing the chance of sperm and egg meeting.

Sperm can survive for 85 hours in the fallopian tube. The fallopian tube fluid contains enough sugar and necessary chemicals for sperm survival.

The length of sperm survival depends on the composition of cervical fluid and fallopian tube fluid, and these factors are different in each menstrual period. It is possible that at some time, cervical fluid blocks the entry of sperm. Because the vagina is a highly acidic environment, sperm that cannot enter the cervix can only survive for two to six hours.

Therefore, the time that sperm can survive in a woman's body varies greatly, ranging from two hours to eight days, depending entirely on the woman's physiological conditions at the time of ejaculation.

In the above article, we learned how long sperm can survive. First of all, after the sperm is discharged from the body and enters the female body, it will only survive in the body for about 8 days. If the sperm can combine with the egg in 8 days, it means pregnancy will occur.
