Nowadays, many older unmarried men and women's first thing after getting married is to have a child. If they want to get pregnant, it is best to understand some knowledge about conception in advance. Some people do not know how long it takes for the egg to be fertilized. Under normal circumstances, the survival time of the egg is within 24 hours. During these 24 hours, we need sperm for fertilization. If we miss this time, we will have to wait until the next ovulation period.
On the 6th to 7th day after fertilization, the blastocyst begins to implant. The implantation site is usually located in the upper one-third of the uterus. The completion of implantation means that the embryo has been placed and the placenta has begun to form, giving birth to the fetus.
The first step is for sperm and eggs with fertilization ability to meet at the ampulla of the fallopian tube and prepare for fertilization here. The egg released from the ovary has a fertilization ability that lasts for about 12-24 hours. If it fails to meet the sperm during this period and achieve fertilization, it gradually degenerates and dies, being absorbed or expelled from the body.
When having sexual intercourse, men usually ejaculate about 200-400 million sperm each time, however, most of the sperm are discharged from the vagina with semen. The uterine contractions and fallopian tube peristalsis caused by sexual intercourse accelerate the movement of sperm. The fastest time for sperm to reach the fallopian tubes from the vagina is only a few minutes, the latest is 4-6 hours, usually 1-1.5 hours, and the entire process takes about a week until reaching the endpoint.
After fertilization, the egg develops and moves towards the uterus. It reaches the uterine cavity 3-4 days later and is buried in the nutrient rich endometrium 6-8 days later before continuing to develop into a fetus.
Precautions for the combination of sperm and egg: Mastering how long it takes for sperm and egg to combine can be helpful for conception, but some precautions during this period should also be taken into account. Women should control their ovulation time well, and it is best not to engage in sexual activity during the first 5 days of ovulation to ensure sufficient sperm count for ovulation. On the day of ovulation, sexual activity can be carried out, and the best time is between 5 pm and 7 pm in the afternoon. Sexual activity can still be carried out 3 days after ovulation, and there is still a possibility of pregnancy.
If couples want to have a baby, we must understand how long it takes for sperm and egg to combine, as well as the activity cycle of egg and sperm, which will be more helpful for conception. Generally, one week after sexual activity, women can determine whether they have successfully conceived. If sexual activity is carried out during ovulation, the chances of pregnancy will be greatly increased.
