[The influence of sexual experience on sexual motivation and copulatory behavior in male rats].

The influence of sexual experience on male behavior induced by a possible sexual or social partner was studied in 12-month-old Wistar rats in direct interaction or under conditions excluding their direct partner contact. Sexually experienced males demonstrated an interest towards a social partner situated behind the partition to a greater extent than sexually naive males, whereas in direct contact sexually naive males showed greater communicative behavior than experienced ones. All the males demonstrated greatest activity in the presence of a receptive female.
