Polyendocrine Metabolic Ovarian Syndrome (PMOS)
Polycystic Ovary Syndrome (PCOS) has officially been renamed to Polyendocrine Metabolic Ovarian Syndrome (PMOS) (as published in the Lancet Medical Journal, May 2026) to better reflect that it is a complex, whole-body hormone and metabolic disorder rather than just a gynecological issue. The name change addresses a long-standing misconception, as the "cysts" associated with the condition are harmless, underdeveloped egg follicles rather than painful, true cysts.
Despite the new name, the actual symptoms—such as irregular periods (with related infertility), weight gain, acne, and excess facial or body hair—and the medical criteria used to diagnose it remain the same. Doctors adopt this updated terminology to ensure patients receive more comprehensive care that focuses on long-term metabolic health, including managing insulin resistance and reducing the risk of diabetes.
From a fertility perspective, nothing really changes except the name. The goal of treatments will be to regularize menstrual cycles through medications and lifestyle changes, induce ovulation, or in some cases, bypass the condition by doing IVF to achieve pregnancy.
