About one-quarter of births in western countries are induced using synthetic oxytocin. The oxytocin system plays an important role in human social behavior, so it's not well understood how exposure to high levels exogenous oxytocin during birth influences social behavior later in life. In this study, Guastalla and colleagues assessed the association between autistic-like behaviors and synthetic oxytocin exposure during birth in a cohort of 2,868 individuals from the Western Australia Pregnancy Cohort Study. There was no significant difference in child behavioral problems or autistic-like behaviors later in life, suggesting that it is unlikely that perinatal exposure to exogenous oxytocin contributes to autistic-like behaviors later in life.
