If the ovarian cysts are physiological, they will disappear after menstruation. This is due to the fact that most physiological ovarian cysts are caused by luteinizing cysts, which are mostly seen in the formation of corpus luteum after ovulation. If the corpus luteum is relatively large in size, the cysts can be found on top of the ovary, and they will disappear when the progesterone level in the body decreases after a woman’s menstruation. If the cyst still exists after menstruation, it is not a physiological ovarian cyst, but a pathological one, and it is necessary to go to the hospital every 3-6 months to review the ultrasound, to observe the growth rate of the cyst, and if the growth rate is too fast, it is necessary to consider that it is something malignant.
