Rotterdam Criteria: 2 of 3 required for PCOS diagnosis
Oligo/Anovulation
Irregular, infrequent, or absent menstrual periods indicating disrupted ovulation.
Clinical Hyperandrogenism
Signs of elevated androgens including acne, hirsutism, or androgenic alopecia.
Polycystic Ovaries
Polycystic ovarian morphology on ultrasound (requires clinical evaluation).
How PCOScan Works
Assess menstrual regularity, cycle length, and ovulatory patterns.
Visual pattern-matching for acne distribution, hair growth, and hair thinning.
Family history, age of onset, and prior clinical evaluation.
Transparent symptom scoring with point breakdown and physician referral guidance.
Built for Rigor
Every point in the risk score maps to a specific criterion from the 2003 Rotterdam PCOS consensus.
See exactly which symptoms contributed how many points, with no black box. Includes a Judge Mode for presentations.
Safety-first throughout. PCOScan is a symptom pattern assessment, never a diagnosis. Always directs to physician follow-up.
Step 2 uses illustrated acne distribution diagrams. Tap your pattern rather than trying to describe it in words.
Create an account to log symptoms over time and build a picture you can share with your doctor.
Your health data is yours. No ads, no data selling, no tracking beyond what you explicitly log.

A PCOS diagnosis requires clinical evaluation including physical examination, laboratory testing, and in many cases pelvic ultrasound. Always consult a qualified physician.
