title: GENOTYPE AND SEX DRIVE IN INTACT AND IN CASTRATED MALE MICE.
abstract: Male mice of two inbred strains and one hybrid strain were observed for sexual behavior for 42 consecutive days. Half the males of each strain were then castrated, and daily testing was continued until the ejaculatory reflex was lost. Strain differences were found in ejaculatory frequency both before and after castration.
