Manly Sweat Makes Other Men More Cooperative

Effect is more pronounced in men with high testosterone

Excerpt: “I didn’t know that this pheromone could interact with testosterone at all,” Rantala says.

Excerpt:  “We don’t know whether we would be able to observe a similar effect with [the] use of more realistic concentrations.”

My comment: Based on what I have detailed in a series of published works that include our award-winning review: Human pheromones: integrating neuroendocrinology and ethology and my award-winning journal article/book chapter: The Mind’s Eyes: Human pheromones, neuroscience, and male sexual preferences, we used a species-specific mixture of 1 mg/ml androsterone and 4 mg/ml androstenol that altered women’s observed flirtatious behaviors and their self-reported level of attraction. See: Human pheromones and nutrient chemicals: epigenetic effects on ecological, social, and neurogenic niches that affect behavior.

The authors of the article excerpted above state: “Our study was the first to integrate the two distinct branches of research: human pheromone research and research on decision making behavior.

1) There are no indications that they used a species-specific human pheromone. 2) Pheromones are found in mixtures. 3) Exposure to 30 mg of a crystalline compound does not represent “real life” exposure.

This study is not the first to claim to be “…the first to integrate…” anything. It may be the first to use yeast as a control, however.  The potential confound that should be addressed is that the alpha-mating pheromone of brewer’s yeast induces a luteinizing hormone (LH) response from cultured rat pituitary cells.  This suggests that the yeast they used could also alter testosterone levels via the epigenetic effects of pheromones that clearly extend across species from microbes to man.

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.
