Hi Ladies, does anyone know the difference? My doctor referred me to a specialist in recurring loss in NJ, he's an MFM and strongly recommends I see him for my 2 losses to determine the issue. I am also seeing a RE. I saw her today, she did blood test on myself and my husband for chromosomal issues, thyroid, testing sperm, etc. I'm going in for a saline ultra sound once I get my period. What is the difference? I noticed his (MFM) panel does something with egg quality too. I'm so confused and my husband said he only wants to deal with one doctor and he likes the RE. She's fast, smart, efficient, experienced, and based in the hospital ward that specializes in Reproductive medicine in the hospital.
