PCOS is typically diagnosed via the Rotterdam Criteria which consists of four categories:
1️⃣Irregular menstrual cycles – typically defined as greater than 45 days apart or less than 10 per year
2️⃣Clinical or laboratory evidence of elevated male hormones (hyperandrogenism)
2️⃣Ultrasound findings consistent with polycystic ovaries and the absence of any other cause. The diagnosis is made when two of the three criteria are present. Also, keep in mind this syndrome is a spectrum and will have variable presentation and symptoms.
