There is a Reproductive group at UNC. I was seeing a doctor there though I was not trying to conceive. Their 3 year fellows were involved in PCOS studies back in 2000-2001 and might have some new ones too. The doctor I saw is no longer there though since her fellowship ended.

I just had an appointment last Friday with Dr. Ann Brown at Duke, but she is not classified as a "reproductive" endo, just straight endo, though she is a PCOS "specialist". I was pleased with my appointment and her NP was extremely knowledgeable as well. I am waiting on the results of my 2 hr GTT from Friday. She is open to use of Glucophage and does use it on many of her patients, but as I just started working out at a gym again (3 weeks!) she advised we wait to see how that goes. I have a follow up in 4 months with her NP.
