Patient's question:
What is the difference in women's body temperature during the menstrual period, ovulation period, and safe period? How is it normal?Doctor's answer:
Basal body temperature can accurately reflect the function of ovarian ovulation and the corresponding endocrine changes. Generally, this ovulation period temperature change is a simple and effective self-monitoring method and approach for determining ovulation. Therefore, it can also effectively determine whether ovulation has reached a safe period.Medical Advice: The basal body temperature during a woman's ovulation period is primarily characterized by the follicular phase before ovulation, when the ovary secretes estrogen, and the basal body temperature is mostly maintained below 36.6°C. After ovulation, the ovary forms a corpus luteum, which secretes progesterone. Progesterone has a thermogenic effect on the central nervous system, raising the basal body temperature by 0.3-0.5°C. The date of the lowest temperature may be closest to the date of ovulation. On the fourth day of experiencing a high temperature, ovulation has definitely occurred. Therefore, for patients, sexual intercourse from this point onward until the next menstrual period is considered safe. Some basal body temperatures rise in a stepwise manner, taking several days to reach their peak, making it difficult to calculate the exact time of ovulation.
