While the effects of pheromones on humans are less obvious than in other mammals, they still strongly affect our behavior. Many pheromones are air borne particles that pass through air after evaporation by the heat of the body. Some pheromones are heavy proteins that cannot be passed through the air by evaporation. These are passed by physical contact such as by kissing or skin-to-skin contact. Kissing occurs in all human cultures and is a way of passing identification pheromones. When a mother kisses her baby, this increases the mother-baby bonding.
Pheromones activate pre-coded genetic programs. They increase production of GnRH (Gonadotropin Releasing Hormone) that starts the pulses and cycles of sex hormones which govern sexual development. GnRH also affects activity in the brain that affects sexual development and behavior.
Pheromones act in two ways. The first is "signal pheromones" that cause others to become aware of your presence and cause immediate changes in behavior by activating certain areas of the brain. The second class is "priming pheromones" which trigger increases in GnRH production and which often require kissing or skin-to-skin contact. This, in turn, increases production of many hormones that affect development, metabolism, and mating behavior. Often, fertile women have difficulty becoming pregnant. In married couples, it takes, on average, six months of sexual intercourse to produce the first pregnancy. One theory is that the woman's body is slowly adjusting to her husband's pheromones before becoming receptive to pregnancy.
