Polycystic Ovaries vs Polycystic Ovarian Syndrome

What is the Difference?

A common confusion among women, is understanding the difference between having polycystic ovaries (PCO) and having been diagnosed with a Polycystic Ovarian Syndrome (PCOS).

PCO refers to an ultrasound scan image of the ovaries that appear to be polycystic (ovaries containing high density of partially mature follicles).

PCOS is a metabolic condition that may or may not come with having polycystic ovaries.

PCOS Without PCO

PCO is more common than PCOS and a patient maybe diagnosed with PCOS without PCO.

For example she may have PCOS with the following symptoms:

  • Irregular periods
  • Increased male hormone in the blood test or associated symptoms such as extra hair growth or acne.

Other conditions such as thyroid or pituitary dysfunction need to be excluded before PCOS diagnosis is made.
