[Inhibition by dehydroepiandrosterone of aggression responses of spayed female mice towards lactating intruders is potentiated by neonatal androgenization].

Female mice of an inbred Swiss strain were injected subcutaneously (s.c.) with either testosterone propionate or oil-vehicle on the day of birth. Once adult (8 week-old), they were spayed, and then treated either with dehydroepiandrosterone (80 micrograms/day s.c. for 15 days) or with solvent. The decrease of biting attacks by dehydroepiandrosterone was definitely more prominent in neonatally imprinted females than in controls.
