- Do Hormones Exist in Humans and Affect Their Behavior?
-
-
- ------------------------------------------------------------------------------
-
- QUESTION: An article I have just finished tells of how hormones may affect
- the reaction of animals and their behavior to one another. Do these
- mechanisms exist in humans and affect their behavior as well?
-
- ------------------------------------------------------------------------------
-
- ANSWER: The release of hormones and the sense of smell has been proven to
- have a definite effect in many kinds of animals, but the relationship between
- human hormone secretions and scents is not fully understood.
- The hormone-like substances that make animals react to one another are
- called pheromones. The substance is released by one individual and prompts a
- change in the physiology or behavior of another.
- When a female dog goes into heat, male dogs all over town are attracted
- to her master's home because of the scent she releases.
- In colonies of naked mole rats, all females but the queen are infertile.
- That's because the queen sends out such a strong odor that the reproductive
- systems of the other females are shut down.
- In humans, however, over ten years of studies have not been able to
- establish beyond the shadow of a doubt that pheromones exist. There were two
- studies though that are caused considerable debate that human underarm
- pheromones can influence menstrual cycles. The research was done by the
- University of Pennsylvania and the Monell Chemical Senses Center in
- Philadelphia.
- The researchers collected underarm secretions from men who wore a pad in
- each armpit. The male essence was then dabbed on the upper lip of women whose
- menstrual cycles were irregular--lasting less than 26 days or more than 33.
- After three months of this "therapy" the women's cycles changed--lasting an
- average of approximately 29.5 days, which is the cycle length associated with
- the highest fertility. The scientists concluded that male scents produce at
- least one pheromone that helps promote female reproductive health. Another
- study with women who lived in close quarters showed that their menstrual
- cycles would eventually begin to coincide. This is believed to be due to
- underarm sweat secretions.
- The research will continue, in the hope of unlocking the secrets of the
- "chemistry" between human beings.
