Polycystic Ovary Syndrome, which has just been renamed Polyendocrine Ovarian Syndrome (PMOS), is the most common hormonal and metabolic disorder affecting women of reproductive age, impacting up to 13% of this population and contributing to nearly 40% of infertility cases worldwide.

The Endocrine Society renames PCOS to Polyendocrine Metabolic Ovarian Syndrome for improved diagnosis and reduced stigma.
