Objectives: To evaluate the in vivo effect of apomorphine sublingual versus placebo on cortical and subcortical brain activation during video sexual stimulation.
Methods: Ten patients with psychogenic erectile dysfunction and six potent controls underwent functional magnetic resonance of the brain during video sexual stimulation after the administration of either apomorphine sublingual 4mg or placebo following a randomized, double blind design. Functional magnetic resonance sessions were performed with a 7-day interval.
