How does fertilization take place?


Maybe you do not know what fertilization is, how long does it take to get pregnant, but in fact, fertilization and conception can only happen when sperm combines with an egg cell. This process is not simple, even it takes a long time for sperm to reach the egg.

The process of fertilization, conception and development of the fetus can only happen when there are two important factors: sperm and egg. The fastest time when the sperm meets the egg is always at the beginning of the tube. The shortest estimated time is about 45 minutes and the slowest is 12 hours. However, if the sperm does not meet the egg, it will have to wait for 2-3 days when the egg is released to be able to fertilize and conceive.
The war begins after sexual intercourse between a man and a woman, after a man ejaculates, about 40 to 300 million sperms will enter the woman's vagina. Here, spermatozoa will start at different locations in the vagina to look for eggs. Millions of sperm will start a race with a distance of about 18cm from the cervix to the fallopian tubes to be able to fertilize and fertilize an egg. Healthy sperm can only move at a rate of 2.5 cm every 15 minutes. The first obstacle that the sperms encounter on the track is the mucus in the cervix. In the days around ovulation, the cervix secretes mucus and becomes loose, slippery, and smooth, making it easy for sperm to swim through. When the sperm meets the egg, it does not mean that they have merged immediately. And sperm also have to "break the eggshell" to get in. Only the strongest sperm can enter because after the sperm has combined with the ovum. The egg will secrete a substance that hardens the shell so that no other sperm can enter.
For the winning sperm, its journey has now officially begun. At this point, the tail is no longer needed, so it separates itself from the body. The first pole releases the nucleus and then disappears. Then the factors of the egg and the sperm meet. A new, unique cell is formed. It is the fertilized and fertilized egg, also known as the zygote. The zygote contains the inheritance of both parents. At this time, the process of fertilization, conception and fetal development begins.
The process of fertilization, conception and development of the fetus is counted from when the sperm combines with the egg to form a zygote. Until the embryo is implanted in the uterus. About 3-4 days after fertilization, the egg is fertilized and fertilized. That is, the zygote begins to gradually move into the uterus to find a place to nest and divide 3 times along the way.
In general, fertilization and conception will take 13-14 days. However, just because the implantation is not complete, you have successfully conceived.
