summary

Basal body temperature refers to the body temperature measured before waking up after a long period of sleep without any activity. The basal body temperature of normal women of childbearing age changes periodically, just like the menstrual cycle. This change in body temperature is associated with ovulation. What is biphasic basal body temperature? Next, I'd like to share my views with you.

What is biphasic basal body temperature?

Women's menstrual cycle begins on the first day of menstruation. The length of the cycle varies from person to person, ranging from 21 to 35 days, with an average of about 28 days. Separated by ovulation day, it is divided into pre ovulation follicular phase and post ovulation luteal phase. The length of follicular phase is not certain, but luteal phase is fixed for about 14 days. On the next day after ovulation, due to the formation of corpus luteum in the ovary, the secretion of progesterone will make the body temperature rise by about 0.6 degrees Celsius, which makes the body temperature change in two phases. The high temperature period lasts about 12-16 days (average 14 days).

If you are pregnant, because the corpus luteum is supported by the hCG secreted by the embryo, it turns into the corpus luteum of pregnancy, continues to secrete progesterone, and the temperature continues to be high. If no pregnancy, corpus luteum atrophy, stop secreting progesterone, body temperature drops, back to the baseline, menstruation.

The basal body temperature of women of normal childbearing age changes periodically, just like the menstrual cycle, which is related to ovulation. If the ovarian function is poor, there is no ovulation and no corpus luteum formation, the body temperature will continue to be low.

matters needing attention

To more accurately determine the ovarian ovulation function, especially in the treatment of infertility, to know the exact date of ovulation, need to do other laboratory tests, in order to make a clear diagnosis, effective treatment.
