Orgasmic aura originates from the right hemisphere.

The authors present a patient with right mesiotemporal epileptogenic region who experienced orgasmic epileptic aura. Twenty-two similar published cases were also evaluated. Among 15 patients with unilateral EEG foci, 13 (87%) had right and 2 (13%) had left focus. All of the nine patients who had sufficient data on ictal onset area had right-sided seizure onset. The authors suggest that orgasmic aura is an ictal lateralizing sign to the right hemisphere.
