Polycystic Ovary Syndrome

What is polycystic ovary syndrome? Polycystic means many cysts

Polycystic ovary syndrome (PCOS) is a condition where at least two of the following occur, and often all three:

  • At least 12 follicles (tiny cysts) develop in your ovaries.
  • Changes in the hormone balance in the ovaries like more testosterone (male hormone)
  • No ovulation. If you do not ovulate then you do not have a period.

You could have polycystic ovaries without the above symptoms furthermore you could have PCOS without multiple cysts in the ovary.

Causes polycystic ovary syndrome

The real cause is not clear. Several factors might contribute. These include


It is mainly control your blood sugar and act on the ovaries to cause them to produce testosterone (male hormone).but women with PCOS have insulin resistance so the cells in the body are resistant to the effect of a normal level of insulin. This will raise the level of insulin in the blood which causes the ovaries to make too much testosterone. A high level of insulin and testosterone interfere with the normal development of follicles in the ovaries. More testosterone level in the blood causes excess hair growth on the body and thinning of the scalp hair.
More insulin leads to weight gain.

Luteinising hormone (LH)

This hormone is made in the pituitary gland. It causes more testosterone production.

Genetic factors


More weight increases insulin resistance
