Human pheromones in tears automagically effect testosterone

Posted on January 10, 2011 by jim.

Automagically adv. Automatically in a way that seems magical.

Most people tend to think that human pheromones automagically effect behavior.  This form of magical thinking is appropriate for those who have little use for biologically based logic. Here’s  an example of biologically based logic:  The putative human pheromone pregna-4,20-diene-3,6-dione links increased progesterone levels to the likelihood of a signal in the tears of women. Predictably, when this signal is found, it will be one that varies with menstrual cycle phase.  That means there will be increased amount of the signal when women are menstruating (and reportedly are more prone to emotional tears).

Although this chemical was reported to act on testosterone via what turned out to be a non-functional human VNO in 1998: , the results reported here in January, 2011 continue to suggest that human pheromones act via a genetically conserved pathway in all mammals. Mammalian pheromones effect gonadotropin releasing hormone and luteinizing hormone/follicle stimulating hormone ratios, which links them to changes in levels of steroid hormones like testosterone. Changes in hormones link the pheromones to changes in behavior.

Predictably, the next report you read about pheromones in the emotional tears of women, will continue to refer to the pheromones as chemosignals, but will also mention that the chemosignals are derivatives of progesterone that automagically cause testosterone levels to decrease in men.  As long as people ignore biological facts, they can continue to assert that there are no human pheromones, just chemosignals that somehow influence human behavior in the same way that mammalian pheromones influence that behavior of all other mammals (e.g., automagically).

Those who are interested in how human pheromones cause changes in human behavior, and can tolerate learning more about biology, are directed to a recent review article:  The Mind’s Eyes: Human pheromones, neuroscience, and male sexual preferences

James Kohl owns, and he has published books and award-winning research journal articles about human pheromones. With colleagues he was the first to show that a mixture of human pheromones increases the flirtatious behaviors of women, and increases their level of attraction to the man wearing the mixture - during a real-life social circumstance lasting 15 minutes.

What is the vomeronasal organ (VNO)?

The vomeronasal organ (VNO) is a cone-shaped organ in the nasal cavity, which is believed to be one of the body's receptors of pheromones. More, specifically, the VNO, which is part of the accessory olfactory system in the nose, does not respond to normal scents, but may detect odorless, barely perceptible pheromones.

Other schools of thought believe that it is not the VNO but rather cells in our main olfactory system and their affects on hormones secreted by the hypothalamus that are responsible for the affects of pheromones.

What are optimized pheromones?

Optimized pheromones are lab-certified pheromone formulations that have the optimum concentration of biologically active pheromones scientifically proven to produce behavior-altering results -- particularly as sexual attractants. Optimized pheromone formulations do not necessarily contain the maximum level of pheromones available on the market, but rather contain the greatest degree (and combination)of human pheromones that trigger a conditioned biological response in humans that, in turn, dictate their sexual behavior. Optimized pheromones also release neurotransmitters that directly modify the behavior of the opposite sex, such as triggering sexual excitement. For example:

Optimized pheromones for men are scientifically proven to bring about an increase in the luteinizing hormone (LH) in women, thereby causing a woman to have a heightened sexual responsiveness to a man. This LH surge elevates a woman's predisposition towards sexual activity.

Optimized pheromones for women are scientifically proven to bring about a biochemical surge in men, thereby causing a man to have a heightened sexual responsiveness to a woman. This biochemical surge is what makes a man fiercely determined to copulate.
