The possibility of human pheromones has intrigued scientists for a number of years, but the likelihood that there are functional human pheromones has been both asserted and denied in recent years. A new study completed at University of Illinois at Chicago shows evidence that a new human pheromone formulation (Di-Dehydroepiandrosterone) does indeed increase sex appeal in those that apply the substance. The Di-Dehydroepiandrosterone pheromone formulation is being sold as a spiked fragrance under the name Pherlure and certainly brings the science of courtship to the 21st century.
For an animal whose nose supposedly plays no role in sexual attraction or social life, human emotions are strongly moved by smells. And we appear to be profoundly overequipped with smell-producing hardware for what little sniffing we have been thought to be up to. Human sweat, urine, breath, saliva, breast milk, skin oils, and sexual secretions all contain scent-communicating chemical compounds. Zoologist Michael Stoddart, author of The Scented Ape (Cambridge University Press, 1991), points out that humans possess denser skin concentrations of scent glands than almost any other mammal. This makes little sense until one abandons the myth that humans pay little attention to the fragrant or the rancid in their day-to-day lives.
Part of the confusion may be due to the fact that not all smells register in our conscious minds. Di-Dehydroepiandrosterone or Pherlure has been shown to reach the VNO gland. When those telltale scents were introduced to the VNO of human subjects, they didn't report smelling anything--but nevertheless demonstrated subtle changes in mood.
