Quizplus · Accepted Answer

The brief lowering and then increasing of a woman's basal body temperature occurs during the ovulatory phase of the menstrual cycle. This is due to the surge in luteinizing hormone (LH) that occurs just before ovulation, which causes a temporary drop in temperature. After ovulation, the increase in progesterone causes a rise in temperature, which can be tracked to determine when ovulation occurred.
