I have PCOS and borderline IR. I take 2000mg of Glucophage and 30 mg of Actos. Gluc alone did nothing for my cycles, but adding the Actos made all the difference. I actually had cycles for the first time in my life!
I haven't had success yet, but we also have male factor issues. I'm hoping the Actos has changed something enough to make my last ivf cycle a success.
Good luck!
