How does ovulation occur

Ovulation in women of childbearing age usually occurs 12-16 days before the onset of menstruation, that is, approximately in the middle of the 28-day menstrual cycle. The cycle phase preceding the ovulation process is called follicular, or estrogenic. Its length can vary from 7 to 22 days, although in some cases (usually pathological) it can reach 40 or more days. In the follicular phase under the influence of hormones, the egg matures and the follicle grows, through which it subsequently leaves the ovary. The moment of release of the egg from the bursted follicle is ovulation. The day in which this occurs is most favorable for conception.

Also favorable for conception are considered 3-5 days before ovulation and a day after it.

The second phase of the cycle is called the luteal phase, or the phase of the yellow body. At this time, the egg moves to the uterus on the fallopian tube. If fertilization has occurred, on the 5th-10th day the embryo is implanted into the uterine wall. If conception did not take place, the egg dies within 24 hours. Approximately two weeks after this under the influence of hormones, there is a rejection of the inner mucosa of the uterus – the endometrium, which externally manifests itself as a regular menstruation.

One common error during pregnancy planning is an attempt to calculate ovulation mathematically or sensations. Counting the days is often a useless occupation. It is much more reliable to determine ovulation with the help of tests, folliculometry (ultrasound) or, in extreme cases, using the basal temperature chart.

Also, do not try to calculate the effect of ovulation on the child`s sex. Despite the”scientific justification” of this kind of theories, in life they do not always work.

Causes of ovulation absence

To become pregnant, if there is no ovulation, it is impossible. The most common cause of its absence is hormonal failure in the body. Also, problems with ovulation may occur after prolonged use of oral contraceptives. In most cases, this is treatable. Obtain ovulation or bring it closer with hormonal therapy.

Ovulation may be absent in women with excessive or underweight. A special treatment is not required in this case. Once the weight returns to normal, problems with ovulation tend to disappear.


After 40 years of ovulation becomes irregular, and therefore get pregnant at this age is difficult. Treatment with hormones in this case is not always successful.
