Study refutes testosterone link to anger

Nearly 500 children from the Western Australian Pregnancy Cohort (Raine) Study were prospectively followed at two, five, eight and 10 years of age after having their cord blood testosterone levels measured at birth.

The study identified no significant relationship between cord blood testosterone levels and overall Childhood Behaviour Checklist scores, internalising behaviours such as anxiety and withdrawal, or externalising behaviours such as aggression, conduct problems and impulsivity.
