25% of women have polycystic ovaries, but not the syndrome. To have the syndrome, you need to also have the high levels of androgens as well. So when we talk about the cause of PCOS, we really means is the cause of high androgens. This also means, that you can’t be diagnosed by an ultrasound alone, you need some blood tests to confirm high androgens.
Excess androgens, even just a small amount, can stop normal menstruation and ovulation. But great news is that its absolutely possible to reduce them and get ovulation again.
