How long after the egg is released is the most likely to be fertilized?

The time it takes for the egg to be released is two to three days. During this period, the chance of pregnancy is the highest. Therefore, this is the most suitable time for couples to have sexual intercourse. So, when is the best time for pregnancy after the egg is released? This problem must be something that many women do not understand. Let’s take a closer look at it next, and I hope it will be helpful to everyone.

How long does it take for the egg to be released before pregnancy is most likely to occur?

The egg cell is produced by what we generally call female sex hormones - the uterus and ovaries, and has a diameter of 0.2mm. The main function of the ovaries, in addition to secreting estrogen essential to women, is to produce oocytes. The prototype of the uterus and ovaries is already formed in girls during the test tube embryo stage at about 3 to 6 weeks of pregnancy. Before birth, there are millions of oocytes produced in the uterus and ovaries. After childhood and puberty, only about 100,000 oocytes remain by the time an adult reaches adulthood. The oocyte is encapsulated in the initial egg. Under the influence of estrogen, only one initial egg is perfected every month. The perfect egg cell is then discharged from the uterus and ovary into the abdomen. Generally speaking, a woman will have about 300 to 400 perfect oocytes in her lifetime, and the rest of the oocytes are left alone.

An egg cell can survive for about 48 hours after being released, during which time it waits to meet and fuse with sperm. If the egg cell cannot meet with the sperm to form sperm-egg fusion after being discharged due to various reasons, it will weave memory after 48 to 72 hours. If you miss the opportunity for fertilization this time, you will have to wait until another egg cell is perfected and released one month later, and the same process will be repeated. The left and right ovaries usually ovulate in turn, and in rare cases, two or more eggs will be released at the same time. If each of them combines closely with the male sperm, dizygotic twins and polyzygotic twins will appear.

Among the causes of female infertility, infertility caused by uterine and ovarian factors accounts for about 15% to 25% of infertility, and uterine and ovarian anovulation is one of the main reasons.

How long does it take for the egg to be released before pregnancy is most likely to occur?

The fertilization ability of the egg is strongest within 15 to 18 hours after being released from the ovary, and can maintain the fertilization ability for about 30 hours. After that, the egg begins to change, and the fertilization ability quickly weakens and disappears. Although sperm ejaculated into the female reproductive system can survive for up to 4-5 days, its strong fertilization ability lasts for 1-2 days. In other words, pregnancy is only possible if you have sex 1-2 days before and after the female ovulation period. This is very important for guiding the sexual life of infertile couples. Some couples have no problem conceiving each other, but they become infertile for many years after marriage because they ignore the opportunity to get pregnant.

Oocyte survival time

How long does the egg live in the body?

Let's talk in detail about the survival time of egg cells in the body. As mentioned above, egg cells always exist in the female body. When a newborn baby girl is born, there are 450,000 eggs in her uterus. Do you find it shocking? But these eggs will not always be there. One day they will decay and die. When the human body can no longer ovulate, the eggs basically complete their journey.

When women enter a stage where they are sometimes independent and sometimes tearful, the egg needs to leave us. When a woman is between 45 and 55 years old, it is basically difficult for her body to secrete eggs, and at this time the egg cells in her body are basically gone. The entire life span of the egg cell in the body is when the woman enters menopause.

In fact, when a woman gives birth, most of her eggs will die. As she gets older and her body becomes weaker, her body functions gradually weaken. At this time, both the eggs and other functions of the body are declining. However, it is a natural process and there is no need to worry.
