Effective sperm fertilization time

Pregnancy is an event that emphasizes probability. Nowadays, due to some environmental factors, human factors, lifestyle and other aspects, it is more difficult for many young people to get pregnant. How to get pregnant quickly is a question that young men and women have always wanted to know. So, when is the time for Y sperm to become pregnant after ovulation? The following editor will give you a detailed introduction.

Y sperm pregnancy time after ovulation

Sperm is produced in the testicles. The process of sperm production is very standardized. It takes 64 days for spermatogonia to undergo seven divisions and become a perfect sperm. Perfect male sperm contains male sperm with X and male sperm with Y. After the male ejaculation enters the female reproductive system, the life cycle is 1 to 3 days. If the sperm cannot meet the egg during this period, it will lose the ability to become pregnant.

Women's reproductive characteristics are regular, and they usually only ovulate one egg per week. The complete cycle of egg cells is only about 14 days. The egg is released and must be fertilized within 24 to 48 hours to become pregnant. Therefore, fertilization within 1 hour after ovulation is the most basic condition for pregnancy. At this time, the freshness and health of the egg cell are the prerequisites for ensuring the health of the test tube embryo.

Male sperm can survive in the human body for three days, so there is a chance of pregnancy if you have sex within three days before or after ovulation. There is a saying on the Internet that the survival time of Y male sperm is generally only one day, while X male sperm can survive for two to three days. If you are preparing for pregnancy, you can have sex within a few days before ovulation, which can increase the chance of pregnancy.

How long does it take to get pregnant after sex

How long does it take to get pregnant after having sex? Generally speaking, women become pregnant within 15-18 hours after the egg cell is released from the uterus and ovary. The egg can survive for two days after being released, so the probability of pregnancy after ovulation is relatively high. For a woman to successfully become pregnant after having sex, she must meet the following criteria.

1. Men's testicles can produce normal sperm

The sperm density of a normal adult male ejaculate at one time is 2-6 ml. The sperm count in 1 ml of semen should be more than 60 million, more than 60% of the sperm are motile, and the abnormal sperm is less than 15%-20%. If the male's sperm does not meet the above standards, it will be difficult for the female to become pregnant.

2. Female ovaries can produce healthy and complete eggs

For women with normal menstruation, there is always a healthy and complete egg cell released in each menstrual cycle, so there is still a chance of pregnancy. It is more difficult for women with ovarian insufficiency or irregular menstruation to get pregnant.

3. Have normal sexual intercourse around the ovulation period

Male sperm can survive in the female reproductive tract for 1-3 days, and the egg cell can survive for about 1 day after being released. The female ovulation time is about 14 days before the next menarche, and the possibility of pregnancy is high within a few days before and after ovulation.

4. The reproductive system is unobstructed

Men's ejaculation duct must be unobstructed so that male sperm can be discharged. Similarly, the female reproductive system must be smooth, so that the sperm entering the female vagina during intercourse can smoothly reach the fallopian tubes and meet the egg cells for fertilization.

5. Uterine extracellular fluid is suitable for embryo implantation and growth and development

After the egg is fertilized, it grows and moves toward the uterus. After 3-4 days, it reaches the uterine body. After 6-8 days, it is buried in the nutrient-rich uterine wall and continues to grow and develop to become a fetus. The combination of sperm and egg and the development of the uterine wall are carried out smoothly. If the sperm and egg combine too early or enter the uterine cavity too late, the uterine wall at this time is not suitable for embryo implantation and continued development, and pregnancy is impossible.
