Blue, Metformin is a drug given to people with type II diabetes. It can be given to PCOS women (and get ovulation working in some cases) as about half of PCOS sufferers have insulin resistance, which is a precursor to type II diabetes. The problem is that not many docs are willing to prescribe it (I had to hassle my doc to prescribe it to me, he didn't think it would work as I'm not overweight and most of the studies have been on large women). Do you have PCOS? I ask because I read of a recent UK study that found taking Metformin increased IVF success for PCOS women.
