pups that underwent prenatal stress showed lower plasma testosterone when compared to the control pups. this is caused by the disruption of prenatal development which did not allow the complete masculinization of the prenatally stressed pups’ central nervous system. particularly in the striatum of the prenatally stressed male pups showed an increase in vanilmandelic acid, dopamine, serotonin, 5-hydroxyindoleacetic acid which all can affect sexual behavior. the prenatally stressed male pups showed a significant latency in mounting behavior when compared to controls.
