You've probably seen it: PCOS is being called by a new name - PMOS. It's real. In May 2026, after more than a decade of work, a global coalition of medical and patient organisations officially renamed Polycystic Ovary Syndrome (PCOS) to Polyendocrine Metabolic Ovarian Syndrome (PMOS).
The condition itself hasn't changed - only its name has, and with good reason. Here's what PMOS means, why the change happened, and what it does (and doesn't) mean for you.
The essentials
What PMOS stands for
PMOS is Polyendocrine Metabolic Ovarian Syndrome. The new name leads with hormones ('polyendocrine') and recognises the metabolic side of the condition - a more accurate description than 'polycystic'.
Why PCOS was renamed
The old name could be misleading: many women with the condition don't have ovarian cysts, and 'polycystic' underplayed its hormonal and metabolic nature. Experts felt the name contributed to delayed diagnosis over the years.
Who made the change
The rename was led by Professor Helena Teede at Monash University, after 14 years of work with patients and clinicians around the world, and involved 56 patient and professional organisations, including the Endocrine Society. It was published in The Lancet on 12 May 202600717-8/fulltext) and announced by the Endocrine Society.
What happens next
A three-year transition has begun. You'll see both names used side by side, and the new name is due to be fully adopted in the 2028 update of the international PCOS guideline. Until then, most doctors, reports and searches will still say PCOS.

Common questions
Is PCOS really renamed to PMOS?
Yes. In May 2026 a global consensus led by Monash University's Professor Helena Teede, involving 56 patient and professional organisations including the Endocrine Society, renamed Polycystic Ovary Syndrome (PCOS) to Polyendocrine Metabolic Ovarian Syndrome (PMOS). It was published in The Lancet on 12 May 2026, with a three-year transition to the new name.
What does PMOS stand for?
PMOS stands for Polyendocrine Metabolic Ovarian Syndrome. The name reflects the condition's hormonal (endocrine), metabolic and ovarian nature more accurately than the older term 'polycystic ovary syndrome'.
Why was PCOS renamed?
Because 'polycystic ovary syndrome' could be misleading - many women with it don't have cysts, and the name underplayed its hormonal and metabolic core, which experts felt contributed to delayed diagnosis. The new name is more accurate.
Do I need to do anything if I was diagnosed with PCOS?
No. It's the same condition - your diagnosis, tests and treatment don't change. You'll simply see the name PMOS used more over time, alongside PCOS during the transition.
Should I still search for 'PCOS'?
Yes, for now. Most information, doctors and patients still use 'PCOS', and it remains widely recognised. PMOS is the new official name, and both are being used side by side while the change settles in.
