What Are Pheromones Used For?


In this article, I discuss what pheromones are used for. Pheromones are used for several things from an evolutionary sense.

To Follow a Food Trail

Another survival instinct occurs when animals are hunting. This has been observed and documented primarily in pack animals.

When one animal picks up on the scent of food, the other animals in the same pack pick up on the same sent quickly often in the form of a pheromone secreted by the first animal who picked up on the scent of food.

Sexual Arousal

Ah — of course. Pheromones have been known and documented as having the ability to cause a sexual arousal in other animals of the same species.

It is interesting that these chemicals will only work on other animals of the same species. This is why we do not see interspecies mating attempts in the wild.

To Be Territorial

Pheromones are responsible for more than just sexual arousal. They are also used for territorial purposes. In insects, pheromones communicate to other female insects that they need to lay their eggs elsewhere.

These are called Epideictic pheromones. Other pheromones the same class can tell other animals of different species to back off and to respect territories.

When one animal marks their territory by urinating, pheromones are at work. Urination often has a repelling scent.

However, the pheromones found in the urine will tell other animals to look for shelter elsewhere.

For Interspecies Bonding

Pheromones play a significant part in nurturing bonds between a mother and a child. The release of these pheromones has been found all throughout the earth, especially in mammals.

Mammals are one of the few types of animals that require the nurturing support of a mother up until a certain age. Pheromones assist in this mother/baby bond.

The Discovery of Pheromones

Gustav Jaeger was a German doctor. He is credited with being the first scientist to identify and document the very idea of human pheromones accurately. However, he did not call them pheromones. Learn more at

Instead, his studies identified them as anthropines.

His studies identified these pheromones as lipophilic compounds found in human skin and in hair follicles and were responsible for an individual human owner's scent signature.

In a very general sense, lipophilic compounds are chemicals that naturally combine with and carry the ability to dissolve in lipids.

It is interesting to note that Dr. Jager did not successfully identify or single out any individual pheromone. It wasn't until 1953 that the first pheromone was identified. This pheromone is called Bombykol and is found in moths and is used by the female to attract a male mate.

Swedish Pheromone Study

A Swedish Study A Swedish study found that lesbians have a different internal, chemical reaction to a particular type of pheromone identified as the AND pheromone than heterosexual women do.

This reaction is distinct because the AND pheromone is 10 times more potent in sweat from men than sweat from women.

4 Kinds of Pheromones

The Four Principal Kinds of Pheromones Scientists have identified four different types of pheromones found in human beings are as follows.

Releaser Pheromones

This is the kind of pheromone that has been linked to sexual attraction and arousal. The effect is usually immediate and the response is reliable.

Primer Pheromones

As the name implies, primer pheromones have to be primed — they take longer to elicit a response. These usually influence the development of reproduction physiology.

They're usually found in the menstruation cycles of females, puberty in both males and females, and can signal the success of pregnancy and reproduction. Primer pheromones have been observed a having the ability to alter hormone levels.

Signaler Pheromones

Signaler pheromones do exactly the name implies — they provide information in the form of signals. These are the pheromones that help a mother recognize her infant offspring by scent.

The fathers typically don't have the same ability. They are thought to signal information such as our genetic odor prints.

Modulator Pheromones

Modulator hormones have been deduced as having the ability to alter or synchronize bodily functions. These hormones are typically found in sweat.

 Scientists have observed a unique trait with these hormones when they are placed directly under the nose of female animals — they usually become a more relaxed and less tense.

It is further believed that modulator hormones are responsible for and may affect the menstruation cycle of females. Learn more about pheromones at
