Infidelity has long been a topic of interest to scientists who study sex and relationships. Over the years, they’ve uncovered a number of surprising things about who’s likely to cheat, why people do it, and the effects that it can have on us and on our relationships. Here’s a look at ten of the most interesting things scientists have discovered to date on the topic of cheating.  

1.) Research has found that certain physical traits and characteristics are linked to infidelity. For instance, men with larger testicles and higher levels of testosterone are more likely to cheat [1].
