According to an article on www.inquisitr.com, scientists have discovered a connection between women’s cheating susceptibility and a specific gene. The lead researcher in the study, Brendan Zietsch from the University of Queensland in Australia notes that, “Isolating specific genes is more difficult because thousands of genes influence any behavior and the effect of any individual gene is tiny. But we did find tentative evidence for a specific gene influencing infidelity in women.” Many factors and emotions, such as empathy, trust, and sexual bonding, contribute to having an affair. Women have a specific gene that allows them to feel these emotions, which are identical to the emotions felt when experiencing “love.” It only makes sense that the same gene allowing women to feel these emotions is also the gene that would effect sexual behavior; the vasopressin receptor gene.
According to researchers, “When vasopressin gets involved with other ‘feel good’ hormones like dopamine and oxytocin, women are helpless and easily succumb to cheating. Interestingly, the very same phenomenon was observed between two closely related, but genetically different species of rodents, one of which was monogamous, while the other was highly sexually promiscuous.”
Studies such as the one mentioned above also demonstrate that sex is not only for the sole purpose of procreation, but reward and pleasure (which may also produce serial cheaters after they’ve experienced an affair).
