#vinmec #benhviendakhoaquoctevinmec #suthutinh #tinhtrung #mangthai The process of fertilization, conception and fetal development can only occur when there are two important factors: sperm and egg. The fastest time when sperm meets the egg is always at the beginning of the fallopian tube. The shortest estimated time takes 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 battle begins after intercourse between men and women, after the man ejaculates, there will be about 40 to 300 million sperm entering the woman's vagina. Here, the sperm will start to depart from different locations in the vagina to find the egg. When the sperm meets the egg, it does not mean that they have combined immediately. The sperm also has to "break the egg shell" to enter. Only the strongest sperm can enter because after the sperm has combined with the egg. The egg will secrete a substance that hardens the shell so that no other sperm can enter. For the winning sperm, its journey now officially begins. At this time, the tail is no longer needed, so it breaks off from the body. The head releases the nucleus and disappears. Then, the nucleus of the egg and sperm meet. A new, unique cell is formed. It is the fertilized and conceived egg, also known as the zygote. The zygote contains the genetic characteristics of both the father and mother. At this time, the process of fertilization, conception and development of the fetus begins. The process of fertilization, conception and development of the fetus is calculated from the time the sperm combines with the egg to form a zygote. Until the embryo implants in the uterus. After about 3-4 days of fertilization, the egg is fertilized and conceived. This means the zygote begins to gradually move into the uterus to find a place to nest and divides 3 times along the way. In general, the fertilization and conception process will take 13-14 days. However, nesting does not mean you have successfully conceived.
