Results: increased flirtatious behavior and self-reported attraction

From 2007 to 2009 we presented results five times during four different scientific assemblies (listed below).  We showed that a chemical mixture of androstenol and androsterone increases flirtatious behavior in women within 15 minutes of exposure. These women also reported that for some unknown reason they were significantly more attracted to the man wearing the mixture. This same mixture is used in the Scent of Eros product for men. If our study results are independently replicated, they will be published – if not before. However, given the bastardization of Kohl’s accurate conceptualization of human pheromones (see his book and journal publications, also listed below), research without publication may continue to be its own reward. From a scientist’s perspective, it makes no sense for researchers to attempt to compete with marketers who are convincing people to buy products that claim to elicit aphrodisiac-like affects on the behavior of the opposite sex. Human pheromone products enhance the appeal of the person wearing them, as you can read in the many unsolicited testimonies you can find in a search for “Scent of Eros.” But there’s no magical aphrodisiac involved; it’s just “chemistry”.

About James V. Kohl 1308 Articles
James Vaughn Kohl was the first to accurately conceptualize human pheromones, and began presenting his findings to the scientific community in 1992. He continues to present to, and publish for, diverse scientific and lay audiences, while constantly monitoring the scientific presses for new information that is relevant to the development of his initial and ongoing conceptualization of human pheromones. Recently, Kohl integrated scientific evidence that pinpoints the evolved neurophysiological mechanism that links olfactory/pheromonal input to genes in hormone-secreting cells of tissue in a specific area of the brain that is primarily involved in the sensory integration of olfactory and visual input, and in the development of human sexual preferences. His award-winning 2007 article/book chapter on multisensory integration: The Mind’s Eyes: Human pheromones, neuroscience, and male sexual preferences followed an award winning 2001 publication: Human pheromones: integrating neuroendocrinology and ethology, which was coauthored by disinguished researchers from Vienna. Rarely do researchers win awards in multiple disciplines, but Kohl’s 2001 award was for neuroscience, and his 2007 “Reiss Theory” award was for social science. Kohl has worked as a medical laboratory scientist since 1974, and he has devoted more than twenty-five years to researching the relationship between the sense of smell and the development of human sexual preferences. Unlike many researchers who work with non-human subjects, medical laboratory scientists use the latest technology from many scientific disciplines to perform a variety of specialized diagnostic medical testing on people.
