PMOS (previously PCOS): guidelines

Below find guideline resources from the Royal College of Obstetricians and Gynaecologists (RCOG), and from the Centre for Research Excellence in Polycystic Ovary Syndrome (CREPCOS)  / European Society of Human Reproduction and Embryology (ESHRE) on the topic of polyendocrine metabolic ovarian syndrome (PMOS), previously referred to as polycystic ovary syndrome (PCOS).

As of May 2026, PMOS replaced the term PCOS, but both terms will appear on this page while organisations transition to the new term and update their guidance.
