In the case of polycystic ovary syndrome, ultrasound examination will reveal more than 12 follicles in each follicle, and the diameter of this follicle will not exceed 9mm, which is highly suspected to be polycystic ovary syndrome. Patients with polycystic ovary syndrome often present with anovulation or sporadic ovulation, prolonged menstrual cycle or amenorrhea, and clinical symptoms such as weight gain and obesity, which should be treated systematically and supervised until menopause.
