Patient's question:
NoDoctor's answer:
It occurs in the middle of the menstrual cycle, releasing an egg while simultaneously forming a corpus luteum. In the pre-ovulatory phase, a large amount of estrogen is secreted, and after ovulation, the corpus luteum secretes a large amount of progesterone. Under the action of estrogen and progesterone, the endometrium transforms from the proliferative phase to the secretory phase; cervical mucus changes from thin and clear to thick and cloudy; and basal body temperature shows a bimodal pattern.
