Metformin increases the chances of conception as well as prevents diabetes. I take it for diabetes prevention, but by chance found out that it also increases the chances of conception (not relevant for me) without the side effects of major infertility treatments. It is not considered an infertility treatment, possibly because it does not increase the chances that much, but - something is better than nothing. I would go see an endocrinologist and ask for a trial of Metformin. If you do not have side effects, you can take it for the rest of your life simply to keep the blood sugar in check. Metformin was developed in 1920's, so it is by now proven safe and is very cheap.
