Advances in functional imaging have allowed to investigate neuroanatomical correlates of sexual arousal (SA) in a noninvasive manner. Objective: To identify the neuroanatomical correlates of SA of healthy men presented with sexually stimulating photographs. Methods: in ten healthy men, functional magnetic resonance imaging was used to study brain responses to the presentation of highly arousing and of nonsexually arousing photographs representing women. Immediately after the fMRI run, rating scales were presented to subjects to assess perceived SA. Volumetric penile plethysmography was performed during scans. Results: both rating scales and plethysmography demonstrated SA in response to sexually stimulating photographs. Regions that were more activated in response to the sexually arousing than to the neutral photographs included bilaterally the fusiform gyri, the inferior occipital gyri, the superior and the inferior parietal lobules, the thalami, the right precentral gyrus, the left caudate body, the right septal nuclei, and the right insula. Conclusion: SA induced by sexually stimulating photographs was related to the activation of a network of regions implicated in the cognitive analysis of visual stimuli, in attentional processes, in motivational processes, the preparation of action and its control, and the assessment of the emotional qualities of bodily sensations.
