question: Hi Doctor, I am 31 yrs old and since Sept 2009 I am trying to conceive without any sucess. My gynecologist did 3 tests (Endomtri biopsy, HSG and Semen analysis for my husband) and told everything is normal. My period is normal. I am on Metformin, my endocrinologist told my insulin is out of normal range. Please suggest what should I do.
