Why a new name?
For decades, this syndrome was reduced to a problem of “polycystic ovaries.” Yet many people affected do not actually have true cysts, and primarily experience hormonal, metabolic, skin-related, psychological, and fertility-related symptoms.
On 12 May 2026, an international consensus published in The Lancet, led by the Endocrine Society and the team at Monash University, officially introduced a new name: PMOS — Polyendocrine Metabolic Ovarian Syndrome.
According to the Endocrine Society, this syndrome affects approximately 1 in 8 women — over 170 million people worldwide. The WHO estimates its prevalence at 10–13% of women of reproductive age, with up to 70% still undiagnosed.
The new name finally puts the whole body at the centre: hormones, metabolism, ovaries — and everyday lived experience.
