What is the rectal temperature for ovulation?

The measurement of rectal temperature is used by gynecologists to assess the woman's reproductive health. More often it is called basal. According to the data obtained, graphs are constructed that help determine the time of ovulation, the presence of hormonal disorders and inflammatory processes in the reproductive tract, as well as the threat of abortion.

On the first day of the cycle, the follicle begins to ripen under the influence of estrogens synthesized in the ovaries. When this process is over, it bursts and an egg leaves it. This ends the first phase of the cycle and the second phase begins.

Then the formation of the yellow body occurs. It synthesizes progesterone. This hormone prepares the endometrium. If pregnancy does not occur, then menstruation begins, this ends the second phase.

Estrogens help to reduce the rectal temperature, and progesterone - to increase it. Thus, in the first phase of the cycle it is low, and in the second phase it is high. Immediately before ovulation, a surge of estrogen is observed, which provides an even greater drop in temperature. However, this phenomenon can not always be fixed when it is measured.

Thus, ideally the rectal temperature for ovulation should be the lowest on the chart. And after it should be a jump up. When plotting a plot along the horizontal axis, the days of the cycle are plotted, and along the vertical axis, measurements are plotted.

Many women who build them, are interested in what temperature when ovulation is the norm. It depends on the individual characteristics. However, in most women in the first phase, the temperature lies in the range 36.4-36.8, and in the second -37-37.2. Accordingly, at the time of ovulation, it should drop below 36.4.

However, if a woman does not detect this phenomenon on her schedule, then you should not get upset. Most of those who build them, it faces this. Most often, the temperature during ovulation lies within the first phase.

The most important thing is that the graph clearly shows the area of low and high temperatures. The presence of a jump and indicates the occurrence of ovulation. Although this is not always the case. With luteinization of the follicle, progesterone is released, the temperature rises, and there is no ovulation, and, accordingly, pregnancy is impossible.

The fact is that the release of the egg from the mature follicle stimulates a sharp increase in the level of LH. By the way, it is he who fixes the tests for ovulation.

However, some women experience a splash earlier than necessary or not at all. In this case, the follicle does not burst, ovulation does not occur, and it lutes, existing until the end of the cycle and secreting progesterone. Experts believe that the graph on this may indicate a long rise in the temperature curve (more than 3 days).

The temperature at ovulation, in the first and second phase can be different from the given norms. This can be an individual feature. Very important is the difference in mean temperatures between phases. The value should exceed 0.4, otherwise this may indicate a lack of progesterone and / or estrogens.

The temperature during ovulation, in the first and second phases, which varies randomly throughout the cycle, may indicate that there is no exit of the matured egg. In this case, the graph resembles a fence, there is no region of high and low temperatures.

The duration of the second phase, which should be more than 10 days, and is better than 14. The high temperature throughout the cycle indicates a large amount of prolactin.

Based on the kind of graphs only, it is impossible to draw definitive conclusions. It is necessary to undergo a hormonal examination, and only then treatment can be prescribed.

Thus, the temperature during ovulation should be the lowest in a cycle. However, this does not happen to everyone. The most accurate method of determining the time of ovulation - folliculogenesis in combination with the delivery of hormones.
