Men don't even know why they cheat,until recently researchers at Karolinska Institute in Stockholm, are stating that they found a correlation between genes of cheating voles( similar to a mouse) and genes of men who cheat on their spouse. The gene was present in 2 out of 5 men studied. The study shows that if you have this gene your more likely to have martial problems. If you have 2 kinds of the gene variant then your in double the trouble. However men who lack the variant are more likely to be devoted to their spouse.

The gene variant studied is believed to regulate the activity of a hormone in the brain and can affect a man's attitudes toward fidelity and monogamy. More than 1,000 heterosexual couples were studied. Researchers looked at men because the hormone is known to play a larger role in their brains than in women's brains. However, the study found that the gene also seems to predict whether women describe their mates as close or distant, and whether the men are more likely to marry, or simply live with their mates.
