The way our body is made up somehow influences our behavioural pattern when it comes down to relationship in life of humanity. In this age, it is not just only men that cheat but the rate at which women cheat is on the high side. In this article, you’re going to see why more and more women and men are struggling with faithfulness.
Whether or not Janet, or any of us, crosses the line from flirty exchanges to infidelity might come down to what's in our DNA, according to a recent discovery by scientists at the University of Texas at Austin.
In a study of women between the ages of 17 and 30, those with higher levels of estradiol (an ovarian hormone that gives a woman the physical characteristics most desired by men like think high cheek bones, symmetrical facial features, and an hourglass figure) were more likely to flirt, kiss, and have a serious affair with someone other than their primary partner than were those with lower levels of this reproductive hormone.
Kristina Durante, Ph.D., a postdoctoral research associate at the University of Minnesota and co-author of this study says I quotes “For women who have more estradiol, their brains essentially tell them, 'You're a hot commodity: Your fertility is high, you can get the best-looking guy with the best resources, so go for it"
It's not that a high level of this hormone makes a woman sleep around, but it may unconsciously inspire her to keep her options open and trade up for a better partner if one comes along particularly if she's not satisfied with her current partner.
In some other researches, we found out that biology can also contribute to that kind of dissatisfaction with a husband or boyfriend and lead any woman to stray, regardless of her estradiol levels. We’ve heard about the research that shows that the more you like a guy's natural scent, the more dissimilar your genetic makeup is likely to be, and the more sexually attracted you'll be to him because of the high chance that you'll make healthy, good looking babies. Sure enough, the more similar a woman's genetic makeup was to her partner's, the less she seemed to enjoy having sex with him and the more likely she was to report having had affairs.
In addition, the more testosterone a male receives in utero, the higher his likelihood of infidelity, says psychiatrist Daniel G. Amen, M.D., a brain imaging specialist and the author of Change Your Brain, Change Your Body. (Here's a clue: If your dude got a hefty dose of the hormone before he was born, his ring finger is likely longer than his pointer finger, says Amen. Go ahead—put down the magazine and check out your guy's hand. We'll wait.)
So far, these biological markers for infidelity in both women and men are out of a person's control. After all, there's no pill for now that can lower estradiol levels in a woman or pump more vasopressin into a man. But there is a physiological cause of infidelity that Amen says we are controlling though we don't realize it:
