Pheromones and detectable odors

Posted on August 1, 2011 by James Kohl.

Sensitivity to the chemicals in food odors and social odors (our pheromones) varies among individuals. Some of the variation is genetic; some is due to individual experiences with odors from different foods or from different people. When concentrations of an odor increase or repeated exposure results in extreme sensitivity to an odor associated either with food or other people, the odor can leave a lasting unpleasant impression. That’s why a few people may not like an odor they associate with the pheromones contained in pheromone-enhanced products. Women raised on farms exemplify this fact; they almost invariably report a negative odor they associated with pheromones in products that contain any of the androstenes. Androstenone, is almost always offensive, and perceived as a urinous odor. But other androstenes: androstadienone, androstenol, and — to a lesser extent — even androsterone can smell urinous to some women, and even to some men. It is not possible to formulate any human pheromone-enhanced product that will appeal to everyone, just as not all foods appeal to everyone.  However, just as we can add spices to food to make some food more appealing, we can add human pheromones to products that make people more appealing to the vast majority of people in their social environment. That’s how pheromones enhance your social experiences, and it’s also how spices enhance your dining experiences.

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.
