Abstract

In all species studied, the medial preoptic area has been found to be necessary for male copulatory behavior. No recovery of sexual function from the medial preoptic area lesions appears to have been reported. This study demonstrates that rats with large lesions of the medial preoptic area exhibit adult male sexual behavior when the surgery is performed prepuberally and the rats have interacted socially with peers.
