Studies have shown a slight increase in risk of infant mortality for births in the 41st and particularly 42nd week of gestation, as well as a higher risk of injury to the mother and child. Due to the increasing risks of advanced gestation, induction appears to reduce the risk for caesarean delivery after 41 weeks' gestation and possibly earlier. Inducing labour after 41 weeks of completed gestion is likely to reduce the risk of perinatal death and stillbirth compared with waiting for labour to start spontaneously.
