NEW BRUNSWICK, New Jersey: Cloning. Artificial Insemination. Big Blue. Any way you look at it, man seems bent on his own obsolescence. Now two Rutgers University professors say they have hit upon the chemical that causes female orgasm, and one of these days they may be able to simulate it. In studies of women with spinal cord injuries, the professors discovered an alternate pathway through which the sensation of an orgasm is sent to the brain. Through the vagus nerve, sensation can travel directly from the cervix, through the abdomen and chest cavity, into the neck and to the brain stem, bypassing the spinal column. That surprising discovery led to the isolation of a chemical called vasoactive intestinal peptide, which Professor Barry Komisaruk says is the neurotransmitter, or nervous system chemical messenger, in the body that causes the orgasm sensation in the brain. Komisaruk mentioned that vasoactive intestinal peptide may have strong pain-suppressing qualities that one day may make it a natural source of pain relief. But other implications were inescapable. Could the ultimate form of Safe Sex be far off? After all, in the go-go brave new millennium, busy women may not have time to get to an Orgasmatron.
