Analgesia produced by vaginal self-stimulation in women is independent of heart rate acceleration.
In the present study, the analgesia produced by vaginal stimulation (VS) in women was found to be dissociated from heart rate. The VS-produced analgesia was not accompanied by an acceleration of heart rate. Heart rate acceleration produced by exercise did not result in analgesia. The independence of VS-produced analgesia from this index of autonomic activity is consistent with recent findings in rats.
