What happens during ovulation?
The presence of ovulation in the menstrual cycle of a woman is evidence of the normal functioning of the reproductive system and reproductive function. The very cycle of a woman consists of several phases. The first of these, follicular, is the period of ripening of the follicle in the ovaries. In the follicle, the egg lives and ripens. If the maturation process is completed, the follicle is ruptured and the mature egg is sent towards the uterine tube. There she is ready to meet with a sperm, which, perhaps, will fertilize her.
At this time, the mucous membranes increase in the uterus. They expand, a special fluid is released, and the cervix dilates. All this is the process of preparing for the egg & bdquo; met & rdquo; with a sperm that could fertilize it. Just this period is the ovulation - the most favorable time of the cycle for the conception of the child and the onset of pregnancy. And if & bdquo; meeting & rdquo; was successful (fertilization took place), then the next menstruation does not occur.
If fertilization does not occur, the uterus is cleared from the endometrium layer, which exits the vagina with menstrual blood and the same egg. In this case, the level of hormones of estrogen and progesterone again becomes normal. In comparison with the time of ovulation, it decreases 4-5 times.
Methods of determination
How to determine the time of ovulation? This question is asked by those who want to become pregnant, and those who fear an unwanted pregnancy. We will name the most common methods.
- The calendar method. If you regularly keep your menstrual calendar, if your cycle is stable and is 28 days, then ovulation with this cycle comes on day 14 from the beginning of menstruation. When the cycle is unstable, you need to add 3-4 cycles and calculate their average duration. In this case, it should be borne in mind that the egg in the body of a woman ripens not every cycle: the older the woman, the fewer months in which ovulation occurs and, accordingly, a mature egg enters the uterus.
- Measurement of basal temperature. This method is somewhat inconvenient in that it requires regularity and strict compliance with the rules. But still, women have been using it successfully since when they did not know about the tests and did not do blood tests for HCG in medical institutions. The essence of the method is the daily measurement of temperature in the mouth or rectum from the very first day of the cycle. These indicators of the thermometer are recorded in a special schedule. At the beginning of the cycle, as a rule, the temperature will be 36, 7-36, 9 degrees Celsius. With the onset of ovulation, it rises to 37-37, 2. It is this increase and is a signal that ovulation has occurred. Using this method, you need to measure the temperature at the same time in the morning, without getting out of bed.
- Ultrasound. Such a study makes it possible to determine ovulation by observing the development of the follicle.
- Tests for ovulation. They are affordable and work on the method of pregnancy tests. The onset of ovulation is characterized by the appearance of two strips on the test. This means that the favorable (fertile) period for the conception has come.
- Tangible changes in the body. It can be pain in the lower abdomen, viscous mucous discharge from the vagina, the onset of a peak of sexuality. A woman at this time feels a special tide of sexual desire.
