D.
I went through infertility treatments a few years ago that lasted several years. Over the years I saw many doctors none of which were Dr. Douglas so I don't have direct experience with him personally. But in hindsight I regret that. Since I've stopped treatments I've heard nothing but wonderful things about him and have the impression that he's the absolute best around. He has alot of experience and he has a high success rate. I know several people personally that had great success with him and have done nothing but rave about him. If he's on your insurance, I wouldn't hesitate.
Good luck.
