do humans produce pheromones
The discussion revolves around whether humans produce pheromones, exploring the implications of pheromones in human behavior, particularly in relation to menstrual synchronization and attraction. The scope includes theoretical considerations, anecdotal evidence, and references to scientific studies.
Participants do not reach a consensus on the existence or effects of human pheromones, with multiple competing views and ongoing debate about the scientific evidence and interpretations surrounding the topic.
The discussion includes references to various studies and articles, but the interpretations of these findings vary among participants. There are unresolved questions regarding the functionality of the VNO and the reliability of anecdotal evidence related to menstrual synchronization.
Pheromones, which have been known to influence sexual activity, aggression, and territory marking, have been found in many animals, including amoebas, fish, hamsters, and monkeys (3). However, whether or not these chemicals affect, or even exist in humans, has been a subject for debate in the scientific community. Since pheromones are not detectable by the human sense of smell, scientists believe that pheromones are sensed by the vomeronasal organ (VNO), part of the olfactory system and located inside the mouth or nose (9). For many years, the existence of the VNO produced much speculation because it had only been found occasionally in adult humans, and when it was found, it was believed to be vestigial. However, in 1985 a study was conducted in which the noses of 100 human adults were examined post-mortem. The VNO was found in the septums of 70% of those examined. Since 1985, much evidence has been gathered to suggest the presence of the VNO in most adult humans (2), but many scientists still believe it to be a functionless organ that was inherited from some ancestor of humans. However, recent genetic research has shown the possibility of a receptor in the nose that could sense pheromones. When searching the human genome for genes that had similar sequences to those of rodent pheromone receptors, scientists found one gene that could produce a pheromone receptor, and when searching olfactory tissue from the human nose, they found this receptor (5).
