The very process of fertilization of an ovum consists of several stages. Let's take a closer look at it and name the main points of each.
How is the process of fertilization of the egg?
Thus, approximately in the middle of the menstrual cycle, the oocyte leaves their follicle. This happens under the influence of hormones that soften its shell and help the matured germ cell enter the abdominal cavity. From there, the egg rushes to the fallopian tube, and is captured by its villi located on the edges.
After this, thanks to the contractile movements of the muscular structures, the egg gradually moves to the uterine cavity. Most often, the process of fertilization of the egg in humans occurs precisely in the fallopian tube.
It is here that many spermatozoa that surround the female germ cell wait for it. Each of them tries to get inside, but more often than not, only one can do it.
Thanks to the enzymatic substances that the sperm head releases, the integrity of the outer shell of the egg is broken. Through the resulting hole, the sperm penetrates inside. In this case, the flagellum of the male sexual cell is discarded, because it is used only for movement and does not contain any genetic information.
If we talk about how to calculate the process of fertilization of the ovule on the days of the menstrual cycle, then only women who have stable and regular menstrual periods can do this with high accuracy. In such cases, the duration of the whole cycle must be taken 14 days, -
Are there signs of the process of fertilization of the egg?
This kind of question is most often of interest to those women who want to diagnose an early possible conception that has occurred. However, to their disappointment, to learn that the egg is fertilized and conception has occurred, the woman is not able.
As a rule, a girl's pregnancy is diagnosed already when there is a delay in menstrual flow, i.e. approximately 2 weeks after sexual intercourse.
