This line graph shows the effect of prenatal exposure to methamphetamine on striatal dopamine levels of male and female adult mice. Adult mice were given two doses of methamphetamine 2 hours apart. One week after the drug injections, their brains were analyzed for dopamine. Males that had been prenatally exposed to methamphetamine had a greater reduction in striatal dopamine levels compared with females and unexposed males. The data for each category follows:

Female Mice:

Male Mice:
