Do Pheromones Actually Influence Human Attraction? A Scientific Exploration
Pheromones have long been a topic of fascination and hypothesis in the fields of biology and psychology. From perfumes promising to improve attractiveness to complex studies examining their role in human behavior, the concept of pheromones remains a subject of considerable debate. This article delves into the scientific evidence surrounding pheromones and human attraction, exploring current research and expert opinions.The Role of Pheromones in Human Attraction
Research has shown that humans do indeed possess and secrete pheromones, which can influence behaviors such as sexual arousal, hormone levels, and fertility. Pheromones are chemical substances secreted or excreted by an organism that elicit specific behavioral or physiological responses in other members of the same species. In humans, these chemicals can be found in a range of bodily secretions, including urine, semen, vaginal secretions, breast milk, and potentially saliva and breath.Scientific Research on Pheromones and Human Behavior
Scientists have long debated the existence and impact of pheromones in humans. A recent study published in Royal Society Open Science provides valuable insights into this debate. The study aimed to determine whether two specific pheromones, androstadienone (AND) and estratetraenol (EST), affected heterosexual participants' attraction to the opposite sex. Both AND and EST are found in male sweat and semen and female urine, respectively.The study involved heterosexual participants rating opposite-sex faces for attractiveness while being exposed to AND and EST. However, the results were striking: there was no observable effect of these pheromones on the participants' judgments. This is in contrast to previous findings that suggested these compounds could influence attraction.
The Divergent Views of Experts
The lack of observed effects has led to disagreements among experts. Researchers such as Simons believe that human pheromones are likely to exist, even if they haven't been definitively identified yet. He views AND and EST as a distraction that might be hindering the search for genuine human pheromones. On the other hand, researchers like Wen Zhou, who conducted a 2014 study showing the influence of AND and EST, contend that these compounds can indeed affect human behavior in a more nuanced manner.Wyatt, a Pheromone researcher at the University of Oxford, advocates for a more thorough examination of human pheromones. He suggests that studies focused on sex and attraction are exploring complex and poorly understood domains of human behavior. Instead, he proposes investigating infant behavior, as these individuals have not yet developed the associations with smells that adults have. Infants, for example, seem to respond to pheromonelike substances from their mothers' areola gland secretions, which prompt them to stick out their tongues and suckle.
Further Research Directions
The current debate highlights the ongoing need for rigorous research into pheromones and human attraction. Further studies are necessary to determine if AND and EST, or other compounds, truly affect human behavior. Tristram Wyatt, a professor at the University of Oxford, hopes that this new work will prompt scientists to re-evaluate their search strategies for human pheromones.Martha McClintock, a behavioral neuroscientist at the University of Chicago, acknowledges that the findings only refute an overly simplified view of AND and EST. She remains convinced that these compounds can influence behavior in more complex ways than previously thought. For example, her recent research focuses on how inhaling AND might affect a person's emotions.
