Diagnosis typically involves a combination of medical history, physical examination, and laboratory tests: 1. Hormonal Assays: Measuring levels of FSH, LH, estrogen, progesterone, and prolactin. 2. Imaging Studies: Ultrasound can assess ovarian morphology and identify any structural abnormalities. 3. Blood Tests: To rule out other potential causes of menstrual irregularities, such as thyroid dysfunction.
