Abstract

The copulatory behavior of 14 male rats was measured following castration. Mating tests continued until the complete disappearance of ejaculations, intromissions, mounts, and incomplete mounts. The results showed that, whereas the ejaculation pattern responses disappeared within 8 weeks from castration, the last intromission was observed in the 18th week, and both complete and incomplete mounts were still performed by one male in the 28th postoperative week. These findings are interpreted as indicating that the motivation to copulate outlasts the sensory and motor components of copulatory behavior after castration.
