PCOS Self-Check (Rotterdam)

Self-check, not a diagnosis. PCOS diagnosis under the Rotterdam criteria requires meeting 2 of 3 criteria AND excluding other causes — that's a clinician's call. This tool helps you organise what you already know about your symptoms before that conversation.

Menstrual cycles

Over the past 6–12 months, your periods have been:

Excess facial or body hair (hirsutism)

Coarse dark hair on the face (chin, upper lip, sideburns), chest, abdomen, or back. Male-pattern distribution. Distinct from typical body hair.

Persistent or adult-onset acne

Cystic / hormonal acne, especially along the jawline and chin. Persistent past adolescence.

Male-pattern scalp hair loss / thinning

Thinning at the crown or temples (rather than diffuse all-over thinning).

Unexplained weight gain or difficulty losing weight

Supportive — not a diagnostic criterion by itself, but common.

Blood test ever shown elevated testosterone or DHEAS

Biochemical hyperandrogenism. If you've had hormone labs done, you may know this; if not, mark No.

Pelvic ultrasound result

Have you had a pelvic ultrasound and what did it show? (PCO appearance = ≥20 follicles per ovary, or ovarian volume ≥10 mL.)

About PCOS. Polycystic ovary syndrome affects 6–13% of women of reproductive age and remains underdiagnosed. The Rotterdam criteria are the most-used diagnostic standard internationally (NIH and AE-PCOS criteria are alternatives). Long-term, PCOS increases risk for type 2 diabetes, cardiovascular disease, endometrial cancer, and infertility — but it's also highly manageable with the right treatment plan. If symptoms are interfering with your life or you're trying to conceive, the conversation with a PCP, OB/GYN, or endocrinologist is worth having.
