The forehead temperature during ovulation refers to the period when a woman's body temperature is the highest, and it is also one of the periods when women are most fertile. During this period, a woman's body temperature will rise by 0.5 to 1 degree Celsius, which is caused by hormonal changes in the body and increased cell metabolism.

In addition to measuring forehead temperature, women can also determine ovulation through other methods. For example, they can observe their own body temperature changes, record their own basal body temperature curve, or determine the ovulation period by measuring a woman's menstrual cycle and body temperature changes.

For women who want to have children, accurate prediction of ovulation is very important for pregnancy and fertility. Therefore, women should pay attention to maintaining good physical condition in daily life and exercise, and try to have sex during the ovulation period to increase the chance of pregnancy.

To sum up, although forehead temperature measurement during ovulation is not always accurate, combined with other methods, it can help women better predict and control their ovulation period, thereby better protecting their fertility and chances of pregnancy. .
