Maternal Fetal Medicine Units Network (MFMU)

Since the inception of the Network in 1986, a total of 58 studies (33 randomized trials and 25 observational studies) have been completed or are in process. As of January 2024, Network investigators have made over 650 presentations and published over 400 peer-reviewed manuscripts. 

The major aims of the MFMU Network are to:   

  1. Reduce the rates of preterm birth, fetal growth abnormalities, newborn morbidity, and maternal complications of pregnancy
  2. Evaluate maternal and fetal interventions for efficacy, safety, and cost-effectiveness

Project Overview:

The network is designed to focus on clinical questions in maternal-fetal medicine and obstetrics, particularly with respect to the continuing problem of preterm birth.

Major findings/impact of study:

A recently completed trial by the Network found that cervical pessary in nonlaboring individuals with a singleton gestation and with a cervical length of 20 mm or less did not decrease the risk of preterm birth and was associated with a higher rate of fetal or neonatal/infant mortality.
