Fertile period

The term fertile period in gynecology is usually understood as the time interval of the menstrual cycle, during which the probability of fertilization of the egg is greatest. It begins with the release of the sexual cell from the follicle and lasts until the time of its death. However, given the physiological characteristics of spermatozoa and their life expectancy, the length of the fertile period of the menstrual cycle is calculated somewhat differently. Let's take a closer look at this parameter, and let's talk about how women plan to conceive a baby correctly calculate it.

How often does the fertile period last?

As already mentioned, the duration of it directly depends on the viability and time of existence of spermatozoa and the egg.

So, usually male sex cells in a favorable environment can maintain mobility up to 3-6 days. That's why, after hitting the female reproductive organs, spermatozoa can remain mobile up to 5 days there.

Taking into account this fact, the fertile period in women is calculated. In order to calculate the window, during which conception is possible, a woman should take 5-6 days from the onset of ovulation. It is at this time that you can make active attempts to conceive a child. To the same women who do not yet plan children, it is worthwhile to be cautious and use contraception during this time period of the menstrual cycle.

From the above, we can conclude that the fertile period in each cycle lasts no more than 6-7 days.

What do you need to know to calculate the fertility period?

Having understood what the fertile period is and when it begins in women, I would like to tell you about the correct algorithm for calculating it.

First of all, a woman should know exactly when she has ovulation in her body. This can be done using a physiological method or using an ovulation test.

The first involves a long-term observation of basal temperature throughout the menstrual cycle. It should be noted that in order to obtain more reliable results using this method, measurements should be performed at least 2-3 menstrual cycles. On the graph of temperature values, the time at which a slight increase in basal temperature occurs to 37-37.2 degrees will be ovulation. It must be said that in view of the strong dependence of the onset of the ovulatory process on external conditions, it is not always possible to determine precisely the beginning of ovulation by this method.

That's why women resort to such a method of diagnosis, as an ovulation test. Following the instructions that are included with the test, a woman can, with an accuracy of one day, determine the time of release of the matured egg from the follicle. This method is the most reliable.

Speaking about the ways of establishing the period of ovulation in the body of a woman, it is impossible not to mention this method, which involves an assessment of the quality and abundance of secretions from the cervical canal. Using it, the girl produces after the past monthly evaluation of the nature of mucus, its viscidity in the first place. In the pre-ovulatory period, the mucus becomes transparent and viscous, externally very similar to the protein of a chicken egg.

Thus, if we talk about whether it is possible to become pregnant not in the fertile period, then this is impossible in principle, in view of the absence of a mature ovum from the follicle. Given this fact, every woman should have an idea of ​​what the fertile period means, and how this time is calculated correctly to conceive a child or, on the contrary, to prevent the onset of pregnancy.
