Seventeen females and eight males exposed during gestation to synthetic progestins showed a significantly higher potential for physical aggression than their sex-matched unexposed siblings. Exposure to androgen-based compounds appeared to be most closely associated with aggressive responses. There were no differences in verbal aggression or IQ between exposed and unexposed siblings.
