Sperm and Egg Cell Movements Before and After Fertilization

It takes about 2-3 minutes for the egg cell to pass through the tube after ovulation, ie egg laying. The zygote (the cell consisting of the combination of the sperm and the egg) stays in the tube for about 3 days, during which the uterus travels inward. In other words, 3 days after spawning, the zygote (now called the blastocyst) is in the uterus. Since the zygote is dividing into the uterus, it becomes a cell cluster containing a cavity called a blastocyst. The blastocyst attaches to the uterus after an average of 3 days (2-4 days) after the uterus is inside the uterus. This is called implantation. So, after a total egg cell release, fertilization progresses to the uterus in the tube and the uterine wall is settled for 6 days. called pregnancy hormone can be detected at the earliest 6th day after laying, even 8-10 days after the laying. The place where the blastocyst is placed in the uterus is mostly located on the midline in the upper part of the uterus wall. The zygote composed of the combination of sperm and egg in the tube becomes an 8-cell ball shaped structure until it reaches the uterus, which is called morula. Morula continues to proliferate before the wall of the uterus is settled, and it becomes a hollow structure with 50-200 cells, called the blastocyst.
