ObGyn. Evidence. Ethics.

I'm an obstetrician–gynecologist and maternal-fetal medicine specialist, and a senior ethics consultant in New York. I write at ObGyn Intelligence (substack.obmd.com), turning evidence into clear, clinically grounded guidance for clinicians and parents-to-be. Evidence first — after 50 years, I see no reason to change that.
