In women with normal menstruation, polycystic will disappear. With normal menstruation, polycystic is mostly a physiological change. Women of reproductive age will have a group of follicles developing every month, usually 3-11 follicles, all developing at the same time during each menstrual cycle. During the development of 3-11 follicles, the strength of the follicles may be balanced, and at the beginning of the cycle, polycystic changes may occur in the ovaries. As the follicles develop, only one follicle grows to 18-23 mm and becomes the dominant follicle, which is the only one capable of expelling eggs, while the other follicles degenerate on their own under the apoptosis mechanism, called follicular atresia. In such cases, women tend to have normal menstruation and normal cycles, so this kind of polycystic ovarian change does not require treatment. Moreover, the number of follicles in this kind of polycystic ovarian change is usually not more than 11, and most of them are less than 10.
