At what average gestational age are most twin pregnancies typically delivered?

Most twin pregnancies are typically delivered around 37 weeks of gestation. This is significant because multiple gestations often lead to a higher risk of premature delivery due to factors such as uterine overdistention and the increased likelihood of complications like preterm labor or preeclampsia.

A delivery occurring around 37 weeks is generally considered full-term for twins, whereas singletons are often delivered closer to 40 weeks. It's important to note that while some twin pregnancies may reach 38 or 39 weeks, the average is lower than that seen with singleton pregnancies. The expectation for earlier delivery reflects the unique considerations in managing the health of both the mother and the babies in a multiple gestation scenario.
