Story summary

International endocrine societies and patient groups renamed PCOS to polyendocrine metabolic ovarian syndrome (PMOS) at the European Congress of Endocrinology in Prague.
Patients' long-standing frustration with the misleading “polycystic” label helped drive the global renaming effort.
