Polycystic Ovary Syndrome Officially Renamed After 14-Year Study
The new name reflects the condition’s hormonal and metabolic effects and aims to reduce missed diagnoses, with 170 million people affected worldwide, experts said.
On Tuesday, medical experts announced Polycystic Ovary Syndrome is officially renamed Polyendocrine Metabolic Ovarian Syndrome , concluding a 14-year global consensus process involving thousands of stakeholders worldwide.
The previous name misleadingly focused on 'cysts' when patients actually have 'arrested follicles,' contributing to missed diagnoses because PMOS impacts metabolic and hormonal systems beyond the ovaries.
Professor Helena Teede at Monash University led the effort involving 56 organizations and about 22,000 global participants, aiming to improve scientific accuracy and reduce stigma linked to fertility.
Lorna Berry, an Australian woman with PMOS who helped lead the renaming, called the shift "accountability and progress," saying it will improve care for future generations of women.
Affecting 1 in 8 women, the condition remains largely undiagnosed; the team plans to integrate the new name into clinical practice over the next three years to ensure equitable healthcare.
