The window of fertility - what is it?

Often, women, referring to doctors for help with pregnancy planning, face the term "fertility window", but what they do not know.

In reproductive medicine, this concept is used to understand the time interval during which the probability of conception is greatest.

How to calculate this parameter?

In order to establish an approximate window of fertility, a woman should know exactly at what time in her body ovulation occurs. It should be noted that in view of the large number of factors that have an indirect effect on the yield of the ovule from the follicles, a shift in the time of the ovulatory process is possible, which complicates the diagnosis.

Despite this, every woman can roughly determine the time when she is most fertile, and it is in this period that she plans to have a pregnancy.

So most often the fertility window opens 5-6 days before the ovulation process . This duration is due to the viability of the male sex cells, which are trapped in the genital tract of a woman, remain mobile up to 5 days. That's why, even if sexual intercourse was a few days before ovulation, a female reproductive cell can be fertilized.

Closure of the fertility window occurs 24-48 hours after the release of the oocyte from the follicle - after this time it dies.

With the help of which methods can correctly calculate the time of ovulation?

Changing the basal temperature is the more common and affordable way. However, it involves the measurement of temperature values ​​for 2-3 cycles minimum.

To more quickly and accurately establish the ovulatory process in the body, ovulation tests can be used. This study takes only 7 days, after which the woman receives the result with high accuracy.

Thus, having an idea of ​​what the fertility window means, how it is calculated for women, and for what it is needed, the girl will be able to calculate the favorable time of conception herself.
