In the ovaries, the sex cells of a woman (ovules) mature, the disorders in which entail problems with the conception of the child. And yet this cell is the strongest among many others.
How many ova in a female body?
Even in the mother's belly, the girl receives a certain number of ovules, which are surrounded by follicles. In a girl born, the number of eggs is several million, and only a few hundred thousand remain to adolescence. It is important to have an idea of how many ovules a woman has, and understand that with age, their number does not increase. On the contrary, it only decreases. In fact, unlike the male sperm, the egg does not renew in the woman. It is believed that by the age of 35 there are only about 70,000 eggs, many of which are defective. But even this number of eggs is usually enough for a woman to get pregnant.
The process of maturation of the egg
The egg begins to mature in adolescence, when the menstrual cycle is established. Accordingly, it is clear how often the ovum ripens from this moment - this occurs once during the monthly cycle. During ovulation, when a mature egg leaves the ovary and is sent to the spermatozoon, the woman has the opportunity to become pregnant.
The period of maturation of the egg can last from eight days to a month, but on average it lasts two weeks. First, under the action of follicle-stimulating hormone, the follicle begins to grow in the ovary. It is known how many ovules in the follicle are just one chosen for ovulation in this cycle. First, the diameter of the follicle with the egg is one millimeter, and after two weeks it already reaches two centimeters. Ovulation occurs in the middle of the cycle, when the pituitary gland discharges a significant amount of luteinizing hormone. The life time of the ovum after ovulation is 24 hours.
A woman lives for about 400 menstrual cycles, which means that thousands of eggs in her body should be enough for conception. But the problem is not only that with the age of the ova becomes smaller, but also in the fact that they gradually lose in their quality. Therefore, it is often important to determine how many oocytes a woman currently has and what her condition is. New methods for determining the reserve of ovaries are being developed. One effective test for the number of eggs is the EFORT test, which determines the response of the ovary to the introduction of follicle-stimulating hormone into the body.
