Summary
A global consortium proposed renaming polycystic ovary syndrome (PCOS) to "polyendocrine metabolic ovarian syndrome" (PMOS) in a May 2026 Lancet consensus paper, endorsed by 56 professional organizations. While most experts agree the original name needed changing due to its misleading focus on cysts, critics at ENDO 2026 questioned both the new PMOS terminology and the process used to develop it, arguing it remains imprecise and insufficiently inclusive of patient perspectives.
