What are pheromones?

Pheromone,  is a chemical messenger (semiochemical) that is secreted outside the body by an individual and is detected by other individuals of the same species through the olfactory organs (such as the accessory olfactory bulb and vomeronasal organ). Substances that cause the latter to exhibit changes in behavioral, emotional, psychological or physiological mechanisms. It has communication functions.

Almost all animals have pheromones. In 1959, it was announced that female silkworm moths secrete sex pheromones, which was the first scientific proof that sex pheromones existed.

The word pheromone is derived from the Greek words "φέρω" (meaning "I carry") and "ὁρμή" (meaning "stimulus"), which together mean "I carry stimulus".

In 1991, scientist David Berliner and his scientific team published research results: they discovered the existence of possible human pheromones androdiene and estradienol, and found that human pheromones are also divided into male and female. It has an activating effect on the hypothalamus, which is responsible for human sexual behavior and endocrine secretion. This has since begun the study of human sex pheromones.

Invisible chemicals emitted by humans play an important role in creating memories. By relieving stress, improving mood, and boosting confidence, they allow us to communicate instinctively when interacting with others.
