PCOS Is Now PMOS—What the New Name Means for the Women It Affects

A May 12, 2026 Lancet consensus renamed polycystic ovary syndrome as polyendocrine metabolic ovarian syndrome, or PMOS.

The change was backed by 56 organizations and more than 14,300 participants to better reflect the condition’s hormonal, metabolic, and ovarian features.

Experts say the new name could reduce diagnostic confusion and improve earlier treatment and long-term risk management for millions of women.
