Polycystic Ovary Syndrome

What is Polycystic Ovary Syndrome (PCOS)?

DotS the definition of PCOS may vary. In Polycystic Ovary Syndrome: Overview, dated 22 January 2026, the World Health Organization’s definition is:

“Polycystic ovary syndrome (PCOS) is a common hormonal disorder that affects women during their reproductive years and beyond, into later stages of life.

PCOS occurs when inappropriate hormonal signaling leads to higher than normal androgen levels and other hormonal imbalances. As a result, women with PCOS may experience irregular or infrequent menstrual periods, pain – including pain with heavy menstrual bleeding, abnormal ovulation, changes in hair (either excessive facial or body hair or female-pattern baldness), oilier skin, acne and/or cysts in the ovaries”.5

In Polyendocrine Metabolic Ovarian Syndrome (PMOS): PCOS Name Changed To PMOS the (Australian) Jean Hailes for Women’s Health explains:

“The name polycystic ovary syndrome suggests a problem with ovarian cysts, whereas polyendocrine metabolic ovarian syndrome reflects the whole-body nature of the condition.

In simple terms:

  • P is for polyendocrine, meaning multiple hormones are involved
  • M is for metabolic, as there’s an increased risk of developing health conditions, like type 2 diabetes and cardiovascular disease, in the long term
  • O is for ovarian, as multiple immature follicles (small fluid-filled sacs) in the ovaries can be seen on an ultrasound, but not in everyone
  • S is for syndrome, reflecting that multiple symptoms are involved, affecting women’s physical and mental health.

It’s hoped the new, more accurate, name will lead to earlier diagnosis and better treatment for women with PMOS.

The condition and method of diagnosis haven’t changed, but now the name fits the true nature of the condition”.6
