Copulins: Human pheromones effect physiology and affect social behavior

Posted on August 14, 2012 by James Kohl.

Finally, there’s news for women interested in pheromone enhancement. We showed that the active ingredients in Scent of Eros for Men increased women’s flirtatious behavior and self-reported level of attraction in the poster available here: Human pheromones, epigenetics, physiology, and the development of animal behavior. A poster presentation at this week’s XXI BIENNIAL INTERNATIONAL CONFERENCE ON HUMAN ETHOLOGY VIENNA/AUSTRIA is reported and linked below:

Human pheromones: Do “copulins” have an effect on men`s testosterone levels and social behavior? (SFA) Xenia Steinbach, Elisabeth Oberzaucher, Karl Grammer

Excerpted from the abstract: This study indicates that copulins affect males both in physiology and behavioral response.

My comment: So far as I know, the copulin formula is the same one used in Scent of Eros for Women. It originated with work by RP Michael et al., which Astrid Juette worked with  under the professorship of Karl Grammer — as detailed in a 1997 presentation at the International Symposium on Olfaction and Taste XII and AChemS XIX.

We added androstenol (and fragrance) to the formula for its positive influence on the woman who wears it. I had no idea it would take this long for replication of the original work, but am glad to see it presented and hope to see it published soon.

For more information on my award-winning work with others from Vienna, including Karl Grammer, the co-presenter of this latest information, see Human pheromones: integrating neuroendocrinology and ethology.

You may also be interested in the slides from my 2010 International Society for Human Ethology presentation.

If you’re still struggling to find accurate representations of what can be done with pheromone-enhancement, you’re in the right place.  As you can see, the links to actual studies and reviews can be followed, as opposed to the wild-goose-chase you’re led on trying to find support for the claims of marketers who are not associated with or Scent of Eros products.

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.
