Medication Abortion and Preterm Birth
Considerable controversy exists about the effects of medication abortion on the incidence of preterm birth (PTB). Medication abortion of various types continues to be touted as a safe alternative to surgical abortion, and without increased risk for PTB. There is a paucity of evidence regarding medication abortion and PTB, but available papers are reviewed here. There is moderate-quality evidence that medication abortions which require surgical completion increase PTB rates more than surgical abortion alone.
