    Abstract

    The role of the cingulate cortex in regulating male sexual behavior was studied in testosterone propionate-treated castrated male rats. Males with lesions in the anterior part of the cingulate cortex showed lower levels of mount, intromission and ejaculation activities than sham-operated control males and males with lesions in the posterior part of the cingulate cortex or the frontal cortex. In male rats in which lateral connections of the anterior cingulate cortex were bilaterally interrupted by sagittal cuts, the sexual activity was much lower than in the control rats, being comparable to that of the anterior cingulate cortex lesion group, but transection of the anterior connections by a transverse cut made in the anterior part of the anterior cingulate had no effect. These results suggest that the anterior cingulate cortex and its lateral connections are critical in regulating male sexual behavior in male rats.
