Hormone condition polycystic ovary syndrome gets new name
· Toronto Sun
A medical condition that affects more than 170 million women worldwide during their reproductive years has a new name.
Polycystic ovary syndrome (PCOS), a hormone health issue in females of child-bearing age, has been renamed polyendocrine metabolic ovarian syndrome (PMOS) following a rigorous global consensus process involving patients, health professionals and organizations, medical journal The Lancet announced .

The former name implied pathological ovarian cysts when in fact the gynecological disorder involves endocrine, metabolic, reproductive, dermatological, and psychological health.
Name change addresses shortcomings
Melanie Cree, a pediatric endocrinologist at the University of Colorado Anschutz who was involved in the renaming effort, said the change addresses shortcomings that has led to delayed diagnoses.
“Renaming this condition is more than semantics — it’s about finally recognizing the full reality of what patients experience,” Cree told the university’s website .
“For too long, the narrow definition of PCOS has overlooked its metabolic and hormonal complexity, leaving many patients undiagnosed or misunderstood.”
The new name also emphasizes the role of ovaries without narrowing down to its reproductive aspects.
“Language matters in medicine,” said Cree. “The previous name often led to misconceptions and stigma, particularly around fertility. This change helps shift the conversation toward overall health rather than a single aspect of the condition.”
Cysts grow on outer edge of ovary
The health condition happens when small sacs of fluid, known as cysts, grow along the outer edge of the ovary . Inside the fluid-filled cysts are immature eggs called follicles. These cysts are unable to release the eggs.
While formerly named for the small cysts, the condition actually involves androgen and insulin.
The authors said up to 70% of affected individuals go undiagnosed.
Women can experience many health effects
On the metabolic side, women can suffer from obesity, type 2 diabetes, hypertension, liver disease, cardiovascular disease, and sleep apnea.
Women’s reproductive health can also be affected by ovulatory disturbances, irregular menstrual cycles, infertility, pregnancy complications, and endometrial cancer.
Psychological effects of the condition include depression, anxiety, poor quality of life, and eating disorders.
In addition, women may experience dermatological effects such as acne, hair loss, and male-pattern hair growth on the face, chest, back, and abdomen.
“PCOS has long been primarily perceived as a gynecological or ovarian disorder; however, mounting research, evidence synthesis, and International Guidelines have shown that PCOS is underpinned by endocrine disturbances in insulin, androgens, and neuroendocrine and ovarian hormones,” authors of The Lancet paper wrote.
The change took more than a decade to occur after the U.S. National Institutes of Health first proposed a new name in 2012.
