Timing of Delivery for Twins.

Abstract

The optimal gestational age for delivery of twin gestations balances the risk to the mother with the risks to the fetus and newborn. Primary considerations should include chorionicity and the presence or absence of other obstetrical complications such as fetal growth restriction or hypertensive disorders of pregnancy. More than half of twin gestations will deliver preterm, and a significant portion will be due to spontaneous labor or medical indications, such that the timing of delivery for twins is typically less determined by the provider discretion. Future studies are needed to assist in clarifying the optimal timing for delivery of twin pregnancies.
