Two studies suggested that pheromone cologne, whose ingredients we are not fully informed of, increases the sexual activity of both men and women when worn by the opposite gendered partner. In other words, you could wear these colognes to increase your chances of having sex.
However, the studies were small and their statistics have been shown to not actually demonstrate any increase in sexual activity. In short, these studies are crap. But if you need more convincing, one of the authors later started a company to sell pheromone colognes. I’m sure that is just a coincidence though…
Flawed Pheromone Studies
Other than the ﬂawed studies mentioned above, there have been no published studies investigating pheromone colognes to the best of my knowledge. So we are left with what we can find on the internet. By far the most popular pheromone products are sold by a company called Androtics Direct. They show customers how to best use the pheromones they purchase. The forum is a treasure trove of information about how to wear pheromones and what to expect.
I have examined each of the effects pheromones are supposed to be responsible for. And it is clear that pheromones don’t exist. Or they have a small inﬂuence on human behavior/physiology in a real-world setting according to http://astrobiosociety.org
Fake Pheromone Forums
The subtle effects that seem more commonly described are, well, subtle. Social interactions are always open to random inﬂuences and multiple interpretations. So, the subtle effects reported could have occurred by chance. Moreover, conﬁrmation bias likely plays a role; people wearing pheromones notice the strange things that happen when they wear pheromones, but they don’t keep track of all the time they wear pheromones and nothing happens.
And ﬁnally, no one on the forums as far as I can tell has done a double-blind experiment in which they wore a cologne that smelled like a pheromone cologne and compared the results they got to their experience wearing a pheromone cologne. Learn more at https://jail6letter.wordpress.com
Finally, in a poll conducted on Pherotalk forum, 60.11% of people felt that pheromones worked, 3.69% of people felt that pheromones don’t work, and 36.20% of people were not sure. This means roughly 40% of people who post on the forum either do not know if pheromones work or believe they do not. Since people who experienced no effects when wearing pheromones are probably less likely to post online, 40% is likely an underestimate of the true number of unconvinced pheromone users. Because of these statistics and the problems with the reliability of the reports, Pherotalk forum does not present methodology. Learn more at http://pheromones-work.weebly.com
Putative Human Pheromones
The three main putative pheromones are androstenone, androstenol, and androstadienone. Each of these chemicals is found in male and female sweat as break down products of the sex hormones testosterone and estrogen. However, only 2 of the 3, androstenol and androstadienone have been investigated in the lab at the time of this writing. Make sure to check out my review of the top pheromones.
