How many days can ovulation survive

In clinical medicine, the treatment effects of infertility in different hospitals are quite different, which has a great impact on our families. However, during the treatment of infertility, we should enhance our scientific understanding of relevant knowledge. So how long can the egg survive after ovulation?

How long does the egg survive after ovulation?

Generally speaking, the egg cell can survive in the body for 1-2 days, and the fertilization ability is strongest within 24 hours after ovulation. Male sperm can survive in the female reproductive system for 2 to 3 days. The chance of pregnancy varies with the proximity of ovulation. Therefore, it is easiest to get pregnant if you have sex during ovulation.

The fertile period of a month is about 10 days before and after the ovulation period, that is, 5 days before or 4 days after ovulation, and the rest of the period is the safe menstruation period. The 48 hours after ovulation is the survival period of the egg cell. In other words, it is best for the egg cell to meet and fuse with the sperm within these 48 hours. However, after the egg is released, if the sperm and egg cannot combine due to various reasons, the egg will die after 48-72 hours.

In rare cases, the female body can release two or more eggs, which is caused by the alternating ovulation of the left and right ovaries. If two egg cells fuse with the male sperm separately, dizygotic twins and fraternal twins will appear.

Under normal circumstances, the fertile period can be calculated based on the survival time of the egg and sperm: Normal women of childbearing age ovulate once a month, and the ovulation period is approximately 12-16 days before the next menstrual period. The egg cell survives for one day, and the male sperm can survive for three days in the female reproductive system. Therefore, if you have sex three days before ovulation or one day after ovulation, the probability of pregnancy is high, which is called the dangerous period of pregnancy. Although sperm can survive for about 2 to 3 days after entering the uterus, its reproductive function can only last for 1 to 2 days. Sperm that has not entered the uterus will not survive for more than 1 day.
