Polycystic O***y Syndrome (PCOS) has long been one of the most common hormonal conditions in women, affecting over 170 million people worldwide. But despite how widely used the term became, experts now say it was misleading in how it described the disease.
A new name has now been introduced: Polyendocrine Metabolic Ovarian Syndrome (PMOS).
This update, published in The Lancet and supported by international medical organizations and U.S. academic leaders (including experts from CU Anschutz), is being described as a major correction in how the condition is understood.

The term โpolycystic o***y syndromeโ implied that the condition:
๐น was mainly an ovarian problem
๐น was defined by ovarian cysts
But modern evidence shows this is not accurate.
In reality:
๐น many patients have no ovarian cysts at all
๐น some are told their ultrasound is normal despite clear symptoms
๐น what is often seen on scans are immature follicles, not true cysts
Over time, this misunderstanding narrowed medical focus to the ovaries, leading to:
๐น delayed diagnosis
๐น overemphasis on reproductive issues
๐น under-recognition of broader health effects

The new name shifts focus to the full disease picture. PMOS is now understood as a multisystem disorder, involving:
๐นHormonal imbalance (polyendocrine dysfunction)
๐นMetabolic dysfunction (especially insulin resistance and weight changes)
๐นReproductive effects (irregular ovulation and infertility)
๐นSkin manifestations (acne, hirsutism)
๐นPsychological effects (anxiety, depression)
๐น Long-term cardiometabolic risks

The change is the result of more than a decade of international collaboration involving clinicians, researchers, and patients.
Experts, including endocrinology leaders such as those at CU Anschutz and pediatric endocrinologist Melanie Cree, highlighted that:
๐นthe old term caused misunderstanding and stigma
๐นit contributed to missed or delayed diagnoses
๐นit particularly affected how fertility concerns were framed
Large global consultations, surveys, and workshops involving tens of thousands of responses repeatedly showed the same issue: the name did not reflect patient reality.
