However if you are looking for permanent cure then PCO cannot be cured per se.There are some surgeries in which they drill holes in the ovaries to help release of ova but not a definite cure.
Most of the time the treatment for PCO is to give hormonal
pills to regulate the periods. But if you want to get pregnant then you need to stop the contraceptive
pill and take up follicular studies along with some other medicines that your Gynecologist will prescribe.
Ideally considering your age and condition it is better to go ahead with conceiving. Waiting may not be fruitful.Do not worry. have a healthy diet and begin physical exercises as it benefits a lot of patients with this condition.
