The diagnosis is often suspected when the woman experiences infrequent, irregular periods associated and with some of symptoms described above but to confirm the diagnosis two out of the following three are required.

• Irregular or absent ovulation (or menstruation)
• Symptoms of excessive androgens or blood test showing androgen excess.
• Ultrasound scan showing multiple small cysts (follicles) on the ovaries.

Many young women are found to have polycystic ovaries on an ultra sound scan but have none of the other features required to make the diagnosis of PCOS. It is important therefore to distinguish between polycystic ovaries as seen on a scan and polycystic ovarian syndrome. Many women with polycystic ovaries, however, may go on to develop PCOS particularly if they put on weight.
