What was PCOS?
A hormonal condition named after the appearance of follicles on the ovaries — a term widely recognised as inaccurate, leading to delayed diagnoses and misunderstood care for millions.
What is PMOS?
A complex, long-term condition involving multiple hormone imbalances, metabolic effects like insulin resistance, and impacts on reproductive, mental, and cardiovascular health — far beyond just the ovaries.
After a decade-long global study with 22,000+ patients and clinicians, the new name was published in The Lancet to reduce diagnostic delays affecting up to 70% of women living with this condition.
