Results: Orgasm induced elevations in cardiovascular parameters and le — Orgasm

"In 2 studies with 10 women each, vaginal self-stimulation significantly increased the threshold to detect and tolerate painful finger compression, but did not significantly affect the threshold to detect innocuous tactile stimulation. The vaginal self-stimulation was applied with a specially designed pressure transducer assembly to produce a report of pressure or pleasure. In the first study, 6 of the women perceived the vaginal stimulation as producing pleasure. During that condition, the pain tolerance threshold increased significantly by 36.8% and the pain detection threshold increased significantly by 53%. A second study utilized other types of stimuli. Vaginal self-stimulation perceived as pressure significantly increased the pain tolerance threshold by 40.3% and the pain detection threshold by 47.4%. In the second study, when the vaginal stimulation was self-applied in a manner that produced orgasm, the pain tolerance threshold and pain detection threshold increased significantly by 74.6% and 106.7% respectively, while the tactile threshold remained unaffected. A variety of control conditions, including various types of distraction, did not significantly elevate pain or tactile thresholds. We conclude that in women, vaginal self-stimulation decreases pain sensitivity, but does not affect tactile sensitivity. This effect is apparently not due to painful or non-painful distraction."

"If you understand the way that the genital system gets to the brain, we can understand pathologies, where there is a blockage—say, in people who don’t have orgasms—where is their system blocked, and why. That’s where we are going now. Once we can understand the natural process, we can understand the pathology and how to attack."

"The idea of thinking yourself to orgasm is not new. In the early 1970s, the Masters and Johnson research team documented the strong connection between sexuality and thought. The connection is particularly strong in women, says Dr. Ian Kerner, author and sex therapist. "The brain is the most powerful sex organ," he says. Men, he adds, have a much harder time making themselves climax without any touch whatsoever, but there are documented cases in women."

"Orgasm is fantastic for your brain. A lot of different regions are activated, which means theyre getting a lot of blood flow. Its kind of a workout for your brain."

"Introduction: The effect of sexual arousal and orgasm on genital sensitivity has received little research attention, and no study has assessed sensation pleasurableness as well as painfulness."

"There is good reason to believe that orgasms while sleeping are not, in fact, the result of genital stimulation, but instead are created in the brain."
