Understanding assessment
People with PCOS do not all have the same symptoms, and an ultrasound finding alone does not establish the diagnosis. In adults, assessment generally considers two of three features: ovulation problems, signs or blood-test evidence of raised androgens, and polycystic ovarian appearance, after excluding other causes. Ultrasound is not always required.
Adolescents need a different assessment approach; ultrasound and AMH are not recommended for diagnosing PCOS in adolescents. Discuss irregular periods, acne or unwanted hair growth with a clinician rather than using this short introduction as a self-diagnosis checklist.
