What is the significance of changes in body temperature during the menstrual cycle?

I believe many people have noticed the changes in body temperature during the menstrual cycle. So, what is the reason for the changes in body temperature during the menstrual cycle? What's the point? These issues are of great concern to everyone, especially for women who want to get pregnant. They want to know whether the changes in body temperature during the menstrual cycle have any guiding significance for preparing for pregnancy. Let us learn about this.

In addition to ovulation, the ovaries also secrete hormones, mainly estrogen and progesterone. Before ovulation, the main process is the growth and maturation of the egg, with the main secretion of estrogen. After ovulation, the follicle forms a corpus luteum, which can produce two hormones, namely estrogen and progesterone. Progesterone can stimulate the body temperature center and cause the body temperature to rise slightly. The body temperature of a normal woman can rise by 0.3-0.5 degrees Celsius after ovulation.

The significance of body temperature changes:

1. Biphasic body temperature can be used as an important indicator of ovulation. The ovulation time is 2-3 days before the biphasic body temperature changes. Monophasic body temperature can confirm that there is no ovulation and corpus luteum formation.

2. It is generally believed that the high temperature period of the body temperature curve should not be less than 12 days, and the increase should not be lower than 0.3-0.5 degrees Celsius, otherwise it is luteal insufficiency.

3. If the high temperature phase of biphasic body temperature (luteal phase) lasts for more than 16 days, conception is possible, which is a good sign for infertile patients undergoing treatment. For those with a history of habitual miscarriage, protective measures should be taken at this time.

People can measure changes in body temperature by checking their basal body temperature. The method is to measure your own temperature after waking up from a long sleep of more than 6-15 hours and before doing any activity. After getting up, record the measured temperature on a basal body temperature sheet, and do this every day to draw a curve.

The normal curve is slightly lower before ovulation and lowest during ovulation; after ovulation, due to the thermogenic effect of progesterone, the body temperature is higher than that in the follicular phase. Therefore, the normal curve is biphasic. In an anovulatory menstrual cycle lacking progesterone, there is no regular change as mentioned above, and the body temperature is consistent and monophasic.

The above introduction lets us know about the changes in body temperature during the menstrual cycle. It can also be seen that getting pregnant is not an easy thing, especially for women with poor physical fitness. Paying attention to the changes in body temperature during the menstrual cycle will be of great help to their own pregnancy. If you don’t know how to measure it yourself, you can also find a professional to guide the measurement.
