The Power of Human Pheromones

Today I am going to break down the power of pheromones. They are all around us and are used by animals, plants, and bacteria. Science has proven that they have incredibly powerful effects upon animals.

For example, female silk moths secret a pheromone that is capable of travelling for miles. If a female bore picks up the cent of androstenol, a pheromone found in the saliva of male bores, she walks on over to her and presents her hind side.

It basically causes sexual arousal. Human reactions are a bit more complicated. The main sensory organ in most animals is the vomeronasal organ which is located in the stem of the nose but its separate from the olfactory organs we normally associate with the sense of smell according to http://heartywomen.com/pheromones-are-important-for-behavioral-communication.

The bottom line is humans do not have a functioning VNO. George Sang at the University of Michigan believed this happened after the development of color vision. Over generations, our vomeronasal organ wilted away. This brought into question whether humans can detect or use pheromones at all thanks to http://www.liceoscientificopitagora.it/ashamed-for-their-pheromones/.

Although the vomeronasal organ excels at detecting pheromones its not the only organ that can do so. Studies have shown that the normal olfactory system can detect them too. We can’t consciously smell pheromones. PET brain scans show that blood flow increases through the hypothalamus when women inhale testosterone and men inhale estrogen. There have been a number of studies that have shown the myriad of effects pheromones can have on humans according to http://mapa-net.net/pherazone-pheromones-arouse-women/.

There are countless examples on record of animals communicating with one another acoustically and visually, but until quite recently there were few examples known which indicated that animals communicated by pheromones. To a large measure this paucity of information is because we humans have a poorly developed olfactory. Recently, however, the development of sensitive analytical techniques and an explosive rise of interest in animal behaviour, have led to increased attention being paid to mammalian pheromone production.

The senses of animals are designed for the maintenance of close contact between the organism and the whole of its environment, both biotic and abiotic. The primary role of olfaction is to make the detection of food and predators possible—its use in communication is, in evolutionary terms, a secondary development although it is of fundamental importance in the creation and maintenance of social organization of mammals and in the control of many facets of behavior.

In the class of mammals, the pheromones sense is extremely sensitive and appears to be highly developed in almost all terrestrial orders. This widespread occurrence is probably due to the very fast rate of mammalian evolution from primitive stock. Early mammals were small predators which doubtless relied heavily on their noses for detection of their prey. To them, an efficient pheromone olfactory system had a strong selective advantage. Their invasion of almost every possible ecological niche has meant that we now see mammals with highly developed olfactory systems in every part of the world and in almost all habitats.
