Characterized by ovulation irregularities, this syndrome is associated with the formation of a large number of small cysts in the ovaries.

But not every ovarian cyst means PCOS. At the heart of the disease are changes in hormone levels. Excessive secretion of male hormones, in particular, called androgens, can negatively affect menstrual patterns and the ovulation process.

Polycystic Ovary Syndrome is not limited to female diseases only. It can also have an impact on metabolism, insulin resistance, and cardiovascular health.
