Description:We used [15O]-H2O positron emission tomography to measure regional cerebral blood flow rCBF in 12 healthy women during a nonsexual resting state, clitorally induced orgasm, sexual clitoral stimulation sexual arousal control and imitation of orgasm motor output control. We propose that decreased blood flow in the left lateral orbitofrontal cortex signifies behavioural disinhibition during orgasm in women, and that deactivation of the temporal lobe is directly related to high sexual arousal. In addition, the deep cerebellar nuclei may be involved in orgasm-specific muscle contractions while the involvement of the ventral midbrain and right caudate nucleus suggests a role for dopamine in female sexual arousal and orgasm. Regional cerebral blood flow changes associated with clitorally induced orgasm in healthy women. Extracerebral markers of sexual performance and orgasm were rectal pressure variability RPstd and perceived level of sexual arousal PSA.
