Built on Evidence
How Yumo's patterns relate to established clinical criteria, and how we keep claims honest before they reach you.
Clinical review
Every piece of clinical content and pattern logic in Yumo is reviewed by a gynecologist and a dietician before it reaches a user. Nothing about symptom weighting or pattern thresholds ships unreviewed. We don't publish specific accuracy or validation numbers until they've been through that same review.
Rotterdam criteria, explained
The Rotterdam criteria define PCOS diagnosis using four phenotypes, based on which of three features are present: hyperandrogenism, ovulatory dysfunction, and polycystic ovarian morphology.
Hyperandrogenism + ovulatory dysfunction + polycystic ovaries
Hyperandrogenism + ovulatory dysfunction
Hyperandrogenism + polycystic ovaries
Ovulatory dysfunction + polycystic ovaries
Our patterns
Yumo's Insight Engine classifies into four patterns, designed to sit alongside — not replace — Rotterdam phenotyping. A clinician's phenotype confirmation always takes precedence over the app's own inference.
Insulin-Resistant
Metabolic and insulin-related signals dominate — often overlaps with Phenotype A/C.
Androgen-Dominant
Hyperandrogenism-driven symptoms are the primary signal — overlaps with Phenotype A/B/C.
Cycle-Irregular
Ovulatory dysfunction is the primary signal — overlaps with Phenotype B/D.
Mood & Stress
Mood, sleep, and stress patterns are the primary signal — considered alongside, not instead of, Rotterdam phenotyping.
