Generally, physiologic follicular cysts take 2-3 months to disappear, but there are individual differences. Physiological follicular cysts are mostly unilateral, and the wall of the cyst is relatively thin, ultrasonography suggests that the cyst has good intracellular permeability, clear boundaries, and tumor markers are normal, no symptoms, follow the doctor’s instructions to observe dynamically, and avoid strenuous exercise. Generally, the cysts can disappear after 2-3 months of observation or oral contraceptive pills, but there are individual differences. However, when the ultrasound suggests that the follicular cyst persists or increases in size, it is necessary to further examine under the guidance of the doctor, such as vaginal ultrasound, tumor markers, etc. There may be the possibility of pathological masses, and it is necessary to decide whether surgical treatment is needed according to the size of the mass and one’s own symptoms. Physiologic follicular cysts can go to the hospital and be observed and rechecked under the doctor’s guidance.
