When does the egg begin to ripen?

Many girls, using as a method of contraception, physiological, are interested in the question of directly when the new egg begins to mature after the past month. Let's try to answer it, having considered features of a menstrual cycle at women.

How and when does the oocyte matured after the menstruation, necessary for fertilization?

To begin with, it must be said that the menstrual cycle itself in women is controlled by several hormones: gonadotropin, follicle-stimulating hormone (FSH), luteinizing, and estrogen and progesterone.

So, during the first phase of the hypothalamus cycle, gonadotropin is produced, which in turn promotes the release of pituitary gland FSH. It is carried by the general blood flow, reaches the reproductive system and stimulates the beginning of maturation of a new egg in the ovaries. In this case, up to 20 follicles are maturing in one cycle, but several of them (1-3) grow faster than the rest. They subsequently release a mature egg.

Then comes the 2nd phase - ovulatory. There is a release of luteinizing hormone, which provokes the rupture of the wall of the follicle and from it a mature egg leaves into the abdominal cavity.

The third phase, luteal, lasts from ovulation until the next menstruation. At this time, the follicle left by the egg turns into a yellow body. This gland synthesizes estrogen and progesterone, which contributes to the thickening of the uterine myometrium, which is preparing for the onset of pregnancy. If the latter does not start, the yellow body decreases, which leads to a decrease in the volume of sex hormones in the bloodstream. Endometrium begins to produce prostaglandins, - substances that cause destruction of the mucous uterus and provoke contractile movements of the muscular layer of this organ.

When exactly does the egg mature after the months?

After examining the process of maturation of the egg, which begins just after the menstrual period, let's try to determine the time frame for this period.

As a rule, the process itself begins literally 3-5 days after the last day of excreta. This happens in the first phase, which, in general, has the same duration.

Many women ask the doctor how to find out when the egg ripens. It must be said that this process has no practical value in calculating "safe" days. For fertilization, the important point is whether ovulation occurs. This can be done by increasing the basal temperature in the middle of the cycle or by performing an ovulation test.
