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 Polycystic Ovary Syndrome (PCOS): What Is PCOS? the (Australian) Jean Hailes for Women’s Health definition is:

“The name polycystic ovary syndrome suggests a problem with ovarian cysts. But PCOS is a condition where polycystic ovaries have more immature follicles (small sacs with eggs) than usual.

The main features used to diagnose PCOS include:

  • Irregular or absent periods
  • Polycystic ovaries
  • High levels of androgens”.6
