Are human pheromones chemosignals?

1959: Pheromones’: a new term for a class of biologically active substances Article excerpt: ”Pheromones are defined as substances which are secreted to the outside by an individual and received by a second individual of the same species, in which they release a specific reaction, for example, a definite behavior, or a developmental process.”

Abstract excerpt: “…cortisol levels are probably not the inducer of the scent of fear and a hypothetical fear pheromone could have other origins.” This article cites Doty (1986):  “Doty [1] described the advantages of olfactory communication as follows: the sense of smell even works if the other two “major” senses (visual and acoustic) are functionally restricted (for example if it is too dark or too loud).” Citation two is Human pheromones: integrating neuroendocrinology and ethology. “Several studies indicate that humans do indeed seem to use olfactory communication and are even able to produce and perceive certain pheromones (for a detailed overview see [2]).”

Article excerpt: “Recent experiments have revolutionized the common beliefs about the control of hormonal responses by pheromones (26, 413). The effects of pheromones on the neuroendocrine status are mediated by a group of neurons in the hypothalamus, which constitutes the endocrine control center (for reviews, see Refs. 89, 245, 353). These neurons secrete the GnRH, also known as LH-RH, which in turn stimulates the anterior pituitary gland to release two gonadotrophins: the luteinizing hormone (LH) and the follicle-stimulating hormone (FSH). Both hormones control the development and the function of the gonads in males and females, although with different effects.”

2012  Article Excerpt:  “It is also clear that, in mammals, food odors and pheromones cause changes in hormones such as LH, which has developmental affects on sexual behavior in nutrient-dependent, reproductively fit individuals across species of vertebrates.” LH release in males “…unequivocally demonstrates that a classically conditioned stimulus can evoke the secretion of hormones from the pituitary gland and testis as effectively as a sexually receptive female.

My comment: Now that we know what pheromones do, and that they do it via the molecular biology common to species from microbes to man, the only reason to not use the term pheromones is to fool people who continue to think human pheromones don’t exist or to make some people think you have discovered something new. There is no problem with either the definition of pheromones or the concept of human pheromones. The problem is with human pheromone-deniers!

Article excerpt: Notes 1. We prefer not to use the term pheromone, as the concept of pheromones is controversial and fraught with problems (Doty, 2010), partly because of widely varying and very strict definitions of what constitutes a pheromone. We instead use the term chemosignal, which according to Doty (2010, p. 186) is less problematic when discussing communication.

Article excerpt:
“…fear and disgust are not only distinctive emotions in the way they are reflected in facial expressions and behavior, but also that they are distinctive with respect to the biomarker profile deposited onto the skin while individuals––in this case, sweat donors––are experiencing these respective emotions.”
My comment: Doty (2010): “The Great Pheromone Myth” is an attempt to redefine “pheromones” and convince others that mammals (e.g., dogs) do not produce pheromones. The “biomarker profile deposited onto the skin” is clearly a mixture of human pheromones that affect emotional expressions in other humans.

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.
