Society for Maternal Fetal Medicine Guidelines for IVF Pregnancies

By: Vinita Alexander, MD

The Society for Maternal Fetal Medicine (SMFM) recently updated guidelines for the management of pregnancies resulting from in vitro fertilization (IVF). Research has shown infertility and subfertility, and pregnancies conceived via IVF, can be associated with small for gestational age neonates and early delivery; thus, SMFM has made the following recommendations for patients pregnant after IVF. All of the SMFM recommendations can be found here

1. Regardless of whether PGT (preimplantation genetic testing) of embryos is performed, all patients pregnant after IVF should be counseled on options for prenatal genetic screening (like cell-free DNA or noninvasive prenatal testing at as early as 9 weeks) and diagnostic testing for chromosomal disorders (like amniocentesis).

2. A detailed, specialized anatomy ultrasound should be performed for all pregnancies resulting from IVF (including assessment of the brain’s third and fourth ventricles, facial features, abdomen, chest, extremities, and placenta).

3. Subfertility and infertility may be associated with an increased prevalence of congenital heart disease. Given this, a fetal echocardiogram should be offered to patients with pregnancies achieved with IVF and ICSI.

4. Recommend specialized monitoring ultrasounds:

  • to evaluate the location of the placenta (to be completed at the same time as the detailed fetal anatomy scan mentioned above)
  • to monitor growth (with at least one growth ultrasound in the third trimester)
  • to monitor development of the fetus and intrauterine conditions (with antenatal fetal surveillance ultrasounds beginning by 36 weeks)

5. Low-dose aspirin is *not* needed for all patients with a pregnancy resulting from IVF. However, if risk factors for preeclampsia are present, this is reasonable.
