The aim of the current project is to investigate the consequences of developmental exposure to antidepressants on the oxytocinergic system. Current research indicates that boys exposed to antidepressants during early development are three times more likely to develop an Autism Spectrum Disorder. Since oxytocin is involved in the regulation of many social behaviors including parenting, social bonding, and "falling in love" we posit an altered oxytocin system may underlie Autism Spectrum Disorder.
