Will Medroxyprogesterone increase my pregnancy rate with PCOS? If not what will? I'm ready to have a child and I want to know what is best?

Not alone. Medroxyprogesterone all by itself won't increase your chances of getting pregnant with PCOS. If your PCOS is keeping you from ovulating, you may need to be on a medication to help you ovulate such as Clomid. This is a prescription medication and needs to be prescribed by a doctor. Best wishes!
