Study results: Human pheromones influence human behavior

Dr. Richard L. Doty’s claim that pheromones in mammals are a myth is again falsified by the presentation of data from a study of student women.  As always, I welcome challenges to our study design, constructive criticisms on our results, and comments on biologically based animal models of behavior that do not incorporate pheromones.  My question to Dr. Doty is:  If mammalian pheromones don’t exist, what shall we call the human pheromones that elicit behavioral affects?

Androsterone, as used here, smells like fresh sweat. It is an individual human male-specific and somewhat primate-specific part of a mixture of axillary chemical secretions that contain androstenol, which influences levels of luteinizing hormone (LH) and mood in women. LH is a hormonal measure of diet dependent sexual maturity and fertility, which is influenced by mammalian pheromones. Mammalian conditioning paradigms suggest that androstenol conditions hormonal effects in females, which may be unconsciously associated with behavioral affects of androsterone in women. We evaluated individual video-taped fifteen-minute interactions of fourteen women with fertile phase levels of LH during a cooperative task. During the task, our male accomplice wore either a standardized androstenol / androsterone mixture diluted in propylene glycol, or just the diluent — with sandalwood odor added to keep him blind to his condition.

When he was wearing the mixture compared to when he wore the diluent, women were more likely to make eye contact (t(12) = 3.43, p = .01; IRR: r = .964, p = .01). They also laughed more (t(12) = 5.20, p <.01; IRR: r = .810, p = .01), and they subsequently rated themselves as being more attracted to him (t(12) = 2.786, p = .016). Our results combine the known effects of androstenol on LH and on mood with a likely behavioral affect of androsterone. They also address contrarian opinions and extend to human females a eusocial insect model for the epigenetic effects of diet and of pheromones on hormone-mediated gene expression during behavioral development. Our mixture characterizes species-specific human pheromones, their epigenetic effects on physiology, and their affect on behavior. Our results are consistent with a validated, unaltered, decades-old, across-species concept of pheromones.

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.
