PCOS Is Officially Renamed, After Decades of Misinformation

A global consortium has renamed polycystic ovary syndrome as polyendocrine metabolic ovarian syndrome, or PMOS.

The old and new names will be used interchangeably for the next three years during the transition.

The change was announced at the European Congress of Endocrinology after a 14-year effort to replace a misleading label.

Advocates say the new name better reflects the condition’s hormonal and metabolic effects, not just the ovaries.

The rename could improve public understanding, diagnosis, and care for the roughly 170 million people affected worldwide.
