title: Neonatal androgen and mounting behaviour in female house mice.
abstract: Strains of intact, mature female mice were found to differ appreciably in their levels of performance of masculine copulatory patterns when presented with a stimulus oestrous female. Balb/c and DBA/2 strains, which showed few responses to stimulus females, were still unresponsive when given exogenous androgen, whereas the C57BL/6Fa strain and its R1 hybrids with the DBA/2 strain, showed more pre-injection masculine responses which increased to consistent and very high levels following androgen treatment. In a second study, injection of Balb/c females with testosterone propionate on the day of birth did not increase the number of masculine responses displayed, even after androgen treatment at maturity.
