It's long been established that people with fewer or weaker dopamine receptors engage in riskier behavior — drug and alcohol abuse, and gambling — to get the same dopamine rush that the average person might get from eating a Snickers. Garcia tested participants, some of whom carried the weaker D4 variant of the dopamine receptor. In fact, Zietsch put a number on it: Not only do the faithful prairie voles have more of these receptors than their cheating cousins, but the receptors are located in a part of the brain that's closer to the reward center. That means women with these genetic changes were more likely to form extrapair bonds, or cheat on their spouses. As we enter the new age of genome sequencing, when knowing our genetic makeup will help prevent diseases and get us better treatments, we really need to stop and consider, how our increasing understanding of our own genetic sequence will change our lives forever. For Garcia, the genetic evidence points to a more nuanced understanding of what it means when somebody cheats in a relationship. Dancers, athletes and musicians all have different genetic versions of AVPR1A, linked together by pathways in the brain we use when connecting with other people. Remarkably, the genetically altered montane vole formed strong pair bonds just like its cousin.

It's long been established that people with fewer or weaker dopamine receptors engage in riskier behavior — drug and alcohol abuse, and gambling — to get the same dopamine rush that the average person might get from eating a Snickers. Of the women studied, 6. Aside from having a hand in these functions, the vasopressin receptor can also influence social behaviours. In fact, Zietsch put a number on it: Science can explain the tendency for infidelity in men, as a man who mates with multiple women will spread his genetic material more widely by leaving behind more children. And when he looked at all participants who cheated in the study, those with the D4 receptor were far more likely to do it multiple times. Oxytocin is another hormone released during sex and also during childbirth and nursing that strengthens social bonds, and female voles with more oxytocin receptors are also more likely to mate for life. Dopamine and Risky Behavior Garcia at the Kinsey Institute conducted a landmark study of dopamine receptors and sexual straying. Hormones and Bonding According to a number of studies, prairie voles have more receptors in their brains for a hormone called vasopressin, which is believed to play a key role in pair bonding. As we enter the new age of genome sequencing, when knowing our genetic makeup will help prevent diseases and get us better treatments, we really need to stop and consider, how our increasing understanding of our own genetic sequence will change our lives forever. But the fascinating finding was that the sets of identical twins — with identical genomes — reported the same exact levels of fidelity, while fraternal twins and regular siblings didn't. Their lives may be short — they're an easy snack for hawks and snakes — but once two prairie voles mate, they are bonded until the end. Vasopressin is a hormone that controls water retention and blood pressure. A vole with an innocent look on his face. For Garcia, the genetic evidence points to a more nuanced understanding of what it means when somebody cheats in a relationship. We may not be able to justify infidelity in women, but we definitely cannot just blame men for the increased need for paternity testing. Remarkably, the genetically altered montane vole formed strong pair bonds just like its cousin. The brains of montane voles, on the other hand, have far fewer vasopressin receptors and therefore make much weaker connections between pair bonding and pleasure. So it's on to the next conquest. That indicates that variations in genes are powerful enough to influence sexual behavior beyond other environmental factors. That means women with these genetic changes were more likely to form extrapair bonds, or cheat on their spouses. Dancers, athletes and musicians all have different genetic versions of AVPR1A, linked together by pathways in the brain we use when connecting with other people. As a society, we are quick to suspect a man of infidelity, illustrated by the booing that often accompanied the arrival of the men on the Jerry Springer show and we are less likely to suspect a woman of cheating on her partner. However, according to recent research, women with certain genetic changes in the AVPR1A gene have an increased tendency to cheat on their partners. Montane voles form weak social bonds and prefer the mating strategy of "use 'em and lose 'em. This explanation may have also tainted our perspective of cheating. Vasopressin isn't the only hormone that's been linked to varying levels of monogamy and infidelity.
