Most of the luteal cysts can be absorbed and disappear on their own with menstruation. This is related to the formation of the corpus luteum, which refers to the outflow of follicular fluid from the follicle after ovulation, and the granulosa cells around the egg are invaginated, and a corpus luteum is formed. If the blood vessels inside the corpus luteum rupture and the corpus luteum is filled with fluid, a corpus luteum cyst is formed, so the corpus luteum cyst is a physiological cyst that appears after ovulation in women. With the end of the luteal phase, the progesterone drops, the endometrium peels off and bleeds, the luteal cysts will shrink, absorb and disappear, but there are a few cases where the luteal cysts still persist after menstruation, if this is the case, you can take short-acting oral contraceptive pills under the guidance of your doctor, usually the cysts will absorb and disappear on their own after 2-3 cycles of taking the pills. In case of luteal cysts after pregnancy, they usually disappear gradually after the third month of pregnancy, because after the third month of pregnancy, the progesterone produced in the body is mainly secreted by the placenta, so the luteal cysts will shrink and disappear.
