Ovarian ultrasonography, preferably accomplished by using a transvaginal approach, can be performed to assess ovarian morphology. Perform ultrasonography if the pelvic examination is inadequate, the patient has abdominal pain, testosterone levels are unusually high (eg, >200 ng/dL), it is needed to support the diagnostic criteria, or the patient is amenorrheic (to assess the endometrial thickness and exclude anatomic causes of amenorrhea). (See the image below.)
