Surely more than once you have been trying to sell a pheromone perfume. If not, you should know that they sell it as a guarantee of success in your appointments. They promise you that just by spraying a light amount of human pheromones on your skin, your lover will fall at your feet.
We know that pheromones are very important substances for animals. For example, dogs that have such good sense of smell use them to communicate. However, scientists have long wondered whether people in pheromones have the same importance as in animals.
There are currently two compounds considered as human pheromones: androstenedione found in sweat and male semen and the stratetraenol that is found in women’s urine. Both substances are steroid hormones.
Can human pheromones influence our attraction to others?
Researchers wanted to know if humans actually secrete chemicals that alter other people’s behavior. To do this, they asked a series of heterosexual participants to evaluate the attractiveness of some faces of the opposite sex. At the same time, they were exposed to different human pheromones to see if they made them more attractive.
They also made a second round, in this case showing images of neutral faces, which had been achieved by mixing images of faces of men and women. The authors suggest that if the participants really felt the effect of the pheromones, the voluntary women would see the neutral faces as men and the voluntary men would see them as women.
What is love? Here is the science
The researchers found effect of steroid hormones on human behaviors. They came to the conclusion that the pheromone label that have androstenedione and the estratetraenol should be suppressed.
The results of the study have been published in the scientific journal “Real Society Open Science”. However, scientists still do not agree on whether or not human pheromones exist. The author of the study says that it has demonstrated that these substances are not, but that does not mean that they can not be other substances that have not yet been identified.
Does human pheromones exist and have been identified?
Tristram Wyatt, a pheromone researcher at the University of Oxford, UK, who was not involved in the work, is convinced that the work is solid and expects researchers to re-evaluate how to look for human pheromones.
Studies that focus on sex and attraction may be exploring a complicated terrain, since human sexual behavior is not fully understood, Wyatt says. Instead, he argues that scientists should examine infants who have not yet developed any association of confounding odors and who appear to respond to some pheromone-like substance that are removed by the areola glands of any mother and is responsible for start breastfeeding.
