Hello,
Polycystic ovaries are the commonest feature seen in majority of women in the reproductive age group with a complaint of irregular or no periods, acne, obesity and/or hirsutism. The condition is essentially a hormonal imbalance with a disturbance of HPO axis and mostly presents with infertility. Yet, it is the one condition that respond very well to treatment. Yasmin(ethinyl estradiol+drospirenone) is a good combination to be used in the treatment of this condition and you can continue with it as long as you need with regular monitoring. Also, maintain a healthy body weight and eat fresh fruits and vegetables, do some regular exercise, as this will help a long way in controlling your problem. Do not worry about having kids-many women with PCOD have a very good reproductive life with treatment. Take care.
