Even in the century before last, gynecologists noticed thatwomen's temperature with menstruation, and also shortly before their onset and at the end varies. And these changes are not the same - before the monthly it rises, and after their offensive decreases.

Later, scientists determined that the reason for the changetemperature is the features of the endocrine system and the ovaries. The most accurate measure in this case is the rectal temperature. This is explained by the fact that with the onset of menstrual flow of blood to the ovaries. To other parts of the body, changes in blood circulation are extremely rare. Sometimes the temperature is measured in the vagina. This method can also give the result of temperature fluctuations during menstruation.

Change in blood supply of internal femaleof the genitals is also explained by the fact that during the period of the month they receive an influx of hotter blood saturated with nutrients and oxygen. Especially intensively, blood flows to the ovaries before the onset of menstruation, and therefore there is an increased fever with menstruation. During menstruation, blood is gradually depleted of oxygen, chemical processes are declining - and the temperature decreases. Simultaneously, the veins of the ovaries flow hormones that were synthesized there before the menstruation.

Rectal temperature is best measured immediatelyAfter sleep, when the body is in complete rest. This temperature is called basal. In addition to the menstrual period, the basal temperature also increases with ovulation and pregnancy. In some cases, basal temperature may give unstable indicators when a woman, for example, is under stress or during long trips (business trips, holidays, etc.).

If basal temperature measurements are carried out withthe first days of menstruation, its indicators can be approximately in the range of 36.5-36.7 degrees. Approximately in the middle of the cycle, when ovulation occurs, the temperature reaches 37 degrees, sometimes slightly higher. The phase of the menstrual cycle before ovulation is called follicular. In such an elevated state, the temperature can be kept at monthly levels until the next cycle. This phase is called lutein. With the onset of menstrual temperature gradually decreases.

Thus, from this small surveythe menstrual cycle clearly shows that the temperature measured in the vagina or rectum increases in the period before the menstrual period, then it decreases after their onset.

Sometimes the temperature with the monthly does not change, thenthere is no reduction in the indices, which is mainly due to pathology. When the menstrual period is accompanied by pain, the temperature can stay high for some time and after the onset of menstruation.

The main reason for the state whenhigh fever with menstruation, is endometriosis, when pain and increased degrees can be observed throughout the entire period of menstruation. Endometriosis causes inflammation of the uterine mucosa, which explains the increase in temperature.

Another reason when the temperature afterthe onset of menstruation is not reduced, but goes up, there may be a pregnancy with insignificant discharge. At the onset of pregnancy, as in ovulation, the temperature inevitably rises during menstruation. And if there is any pathology, then pregnancy is accompanied by blood secretions, and in the first month a woman can take it for false menstruation.

If the woman is healthy and the pregnancy has not occurred,then by observing the basal temperature, you can accurately predict the onset of menstruation. This may be necessary for a non-permanent cycle or when planning any activities (travel, holiday, etc.), especially if a woman feels mildly ill during the menstruation. So, if an increased temperature is detected, a woman can determine that the menstrual cycle is in the state of the second phase, and if it decreases, that menstruation is about to come. For this, the basal temperature should be measured regularly and only at rest. Having thoroughly studied her menstrual cycle and especially the condition of her body during menstruation, a woman can be sure of her health.
