What maternal-fetal medicine (MFM) subspecialists do?

MFM subspecialists are obstetrician-gynecologists who have undergone further training in high risk pregnancies. We partner with patients, their families, and healthcare providers to ensure the best outcomes for both the mother and her baby. We provide counseling, evaluation, and management for the following:

  • women with a previous high-risk pregnancy who want to get pregnant or are already pregnant
  • women with chronic health conditions who want to get pregnant or are already pregnant
  • women with unexpected pregnancy problems including newly diagnosed medical or surgical complications, fetus with complications or birth defects, and multiple pregnancies


Specific services that MFMs may provide include:

  • Routine and specialized ultrasound procedures for pregnant women, including first trimester ultrasound, biometry, biophysical scoring, Doppler, congenital anomaly scan, fetal echocardiogram, and 3D ultrasound
  • Pre- and post-pregnancy gynecologic ultrasound evaluation of the patient
  • Early diagnosis of fetal aneuploidies and other genetic disorders through non-invasive prenatal testing (NIPT) and first trimester screening tests
  • Non-stress test and contraction stress test to evaluate fetal well-being
  • Amniocentesis, amnioreduction, and amnioinfusion
  • Cervical cerclage and pessary insertion to prevent preterm birth
