Polycystic ovary syndrome can be detected with ultrasound, which is recommended through transvaginal ultrasound or rectal ultrasound. In patients with polycystic ovary syndrome, an enlarged ovary, enhanced cystic echogenicity, enhanced interstitial echogenicity, and more than 12 small follicles on either side of the ovary with no mature follicles are usually seen on ultrasound. For a definitive diagnosis, androgen levels and the presence of menstrual disorders, scanty menstruation, amenorrhea, and failure to ovulate should also be tested to determine whether polycystic ovary syndrome has been diagnosed. Patients with polycystic ovary syndrome are advised to go to a regular hospital, cooperate with the doctor to complete the relevant laboratory tests, and actively treat the disease, as well as rest more and maintain a good state of mind.
