Taking a Look at Pheromones

888 Words2 Pages

Pheromones were first introduced by Karlson and Luscher, as chemical messengers secreted from bodies into a surrounding environment (Grammer et al, 2004). This allows for the ability to trigger responses of members of the matching species either physiologically or behavioral (Grammer et al, 2004). Pheromones have been known to have many particular purposes that include acting as: opposite sex attractants, attractants for mother and infant bonding, repelling the same-sex, and regulation of the menstrual cycle (Grammer et al, 2004). Found in the axillary organs as well as the pubic region are the apocrine glands understood as the human pheromone manufacturers (Grammer et al, 2004). Pheromones generate sexual behavior changes as the hypothalamus becomes provoked that causes secretion of Gonadotropin-Releasing Hormone (GnRH), which later causes the release of Luteinizing-releasing hormone (LH) and Follicle-stimulating hormone (FSH) from the anterior pituitary gland (Grammer et al, 2004).

New research has looked towards the Vomeronasal organ (VNO), a region in the olfactory system whose main role is detecting pheromones (Grammer et al, 2004). Recent studies have stated that based on research in mammals that olfaction may lead to an even greater purpose in sexual reproduction for the selection of a mate (Bhutta, 2007). Uncertainty is then raised as the VNO is considered nonfunctioning in some primates and the accessory olfaction bulb is non-apparent in humans (Grammer et al, 2004). However, current studies have demonstrated that humans have an operative VNO that acts specifically in a sex related approach (Grammer et al, 2004). In one study done by Monti-Bloch and Grosser (1991), they observed at whether the human VNO was capable to ...

...ed to pheromones (Grammer et al, 2004). Next, the data in some cases had been self-reported and may have had no real records when comparing the placebo against pheromone known effects (Grammer et al, 2004). This would cause an increase in the proneness to error and subjective bias (Grammer et al, 2004). Another problem with the current research has been that groups differ in many ways with regards to their dating status. The participants in the studies are either married, in a long-term relationship or single. Those participants in relationships would be at an advantage as sociosexual behaviors would be recorded more often that those individuals being single (Grammer et al, 2004). Therefore, the evidence from recent studies does illustrate amplified sexual behaviors but should take into concern greater matching of placebo and pheromone groups (Grammer et al, 2004).
