Part of the diagnosis is finding the symptoms mentioned above. Other tests to confirm the diagnosis include:


This is usually done as an internal scan, meaning a small ultrasound probe is placed just inside the vagina, giving the best views of the ovaries and pelvic organs. In PCOS, the ovaries are found to have multiple, small cysts around the edge of the ovary. These cysts are only a few millimetres in size, do not in themselves cause problems and are partially developed eggs that were not released.


A couple of blood tests will assist in making the diagnosis – one to check the level of androgens, such as testosterone. Another test will measure the hormones involved in egg development – in PCOS there is a characteristic rise in leutenising hormone (LH). A progesterone blood test 7 days before your expected menstrual period can check if you are ovulating.
