Maternal–fetal medicine
（重定向自Perinatologist）
Maternal-fetal medicine (MFM) (also known as perinatology) is a branch of medicine that focuses on managing health concerns of the mother and fetus prior to, during, and shortly after pregnancy.
Maternal-fetal medicine specialists are specialists within the field of obstetrics. They may perform prenatal tests, provide treatments, and perform surgeries. They act both as a consult during lower-risk pregnancies, and as the primary obstetrician in especially high-risk pregnancies. After birth, they may work closely with pediatricians or neonatologists. For the mother, perinatologists assist with pre-existing health concerns, as well as complications caused by pregnancy.
