What Is Polycystic Ovary Syndrome (PCOS)


This is a common hormonal imbalance which may cause a variety of problems.

Please write your picture caption herePCOS is so called because scans of the ovaries show that they contain many small cysts a few mm in diameter. This does NOT mean that you have an “ovarian cyst”, which is a completely different problem. In fact polycystic ovaries are just the most obvious part of an imbalance in the production of several hormones from the ovaries, adrenal glands and the pituitary gland and levels of insulin the body.




People with this condition may complain of some or all of a number of symptoms including:

  • Excess facial and body hair (hirsutism)
  • Irregular or absent periods
  • Difficulty becoming pregnant
  • Some but not all patients are overweight


PCOS is very common. Surveys have shown that perhaps a quarter of normal women, including most of those with a mild excess of facial hair and many of those with slightly irregular periods, suffer from a mild version of the condition.

What Is Prolactinoma/ Hyperprolactinaemia?

A high level of the pituitary hormone Prolactin known as “Hyperprolactinaemia” is the commonest type of overactivity of the pituitary gland. This is often due to a benign pituitary tumour known as a Prolactinoma.




Too much prolactin in the blood may cause the following problem:

  • Irregular or absent periods in women
  • Milky discharge from the breasts and breast tenderness
  • Difficulty becoming pregnant (which is usually reversed by treatment)
  • Loss of libido in both men and women and often impotence in men.
