PCOS is renamed PMOS to reflect endocrine-metabolic roots
Live Science reports that polycystic ovary syndrome (PCOS) will be renamed polyendocrine metabolic ovarian syndrome (PMOS) to better reflect its hormonal and metabolic nature. The term “polycystic” is considered inaccurate since arrested follicles, not cysts, drive many features, and the name has contributed to confusion and stigma. The change was led by an international coalition of 56 organizations, with input from thousands of patients and clinicians, and is set to roll out over about three years. The acronym may continue as PMOS, and there are plans to update diagnostic language beyond ovaries to mirror the systemic endocrine-metabolic effects; this may also stimulate broader research and awareness beyond gynecology.
