Do MFM Doctors Deliver Babies? What MFMs Actually Do

Usually, no. Most maternal-fetal medicine (MFM) doctors do not deliver babies. Their role is to diagnose and manage pregnancy complications, then co-manage care alongside the OB, midwife, or hospital team that attends the birth. A small number of MFMs still perform deliveries, but consultation and co-management is the standard model.

What an MFM doctor actually does

MFM physicians, also called perinatologists, are OB-GYNs who complete three additional years of fellowship training in complicated pregnancy. They manage conditions such as preeclampsia, gestational diabetes, fetal growth problems, and congenital anomalies. For a full overview, see our guide to maternal-fetal medicine.

The work centers on diagnosis and planning. That includes detailed anatomy ultrasounds and expert ultrasound interpretation, genetic counseling, medication management for chronic conditions, and building a monitoring plan the whole care team follows.

Why the delivering clinician is usually someone else

Delivery is a hands-on, local event. It happens wherever the patient labors, often at 2 a.m., and it belongs to the OB, family physician, or midwife who has hospital privileges there.

The MFM's job is to make sure that delivery goes well before it happens. They set the plan: when to deliver, by what route, with what medications, and with which specialists on standby. Some MFMs at academic centers do attend the highest-acuity births, but that is the exception.

How co-management works

Most referrals follow one of three patterns. In a consult-only visit, the MFM evaluates one question and sends recommendations back. In co-management, the MFM follows the complication throughout pregnancy while the OB or midwife continues routine prenatal care and attends the birth. Full transfer of care is reserved for the most complex cases.

Patients in high-risk pregnancy care usually keep their own OB or midwife the entire time. The specialist adds a layer of expertise; the trusted local relationship stays intact.

When there is no MFM nearby

Access is the harder problem. 90.3% of U.S. counties have no practicing MFM, and counties without one are about 56% more likely to have above-average preterm birth rates.¹

Telehealth closes much of that gap. At Ouma, every consult is with a board-certified MFM physician, visits are available within 24 hours, and fewer than 10% of patients ever need an in-person transfer. The local team still delivers the baby. We partner with hospitals and clinics to make that model work in their communities.

Frequently asked questions

Will I still see my regular OB or midwife if I'm referred to an MFM?

Yes, in almost all cases. The MFM manages the complication and coordinates with your OB or midwife, who continues routine prenatal visits and attends your delivery. Full transfer to an MFM practice happens only in the most complex situations, and your referring clinician is part of that decision.

Do MFM doctors perform C-sections?

They are trained to. MFMs complete a full OB-GYN residency, which includes cesarean and vaginal deliveries. In practice, most MFMs focus on consultation, diagnosis, and management, so the delivering OB performs the cesarean while following the delivery plan the MFM helped design.

Does being referred to an MFM mean something is wrong?

Not necessarily. Many referrals are precautionary: age over 35, a chronic condition like hypertension, a prior preterm birth, or a screening result that needs a closer look. An MFM consult often provides reassurance and a clear plan rather than bad news.
