"   Dreaming of a big family? Don&amp;#039;t cheat! A new study shows that people (ok, South American monkeys) in long-term, committed relationships are more fertile than those in unstable ones where one or both partners cheat. It makes sense. The theory behind the findings is that our bodies recognize that having a steady partner &amp;quot;reduces the burden of pregnancy and lactation&amp;quot; and thus produce more baby-makin&amp;#039; hormones. According to the study, fertility is affected regardless of which partner does the philandering, so not only should you dump his butt if he&amp;#039;s gone astray (obviously), but also reign yourself in if you get tempted.  We really shouldn&amp;#039;t need any other reasons not to cheat. Everyone knows cheating it terrible and easily avoidable, right? If you feel like you want to get with another guy, just be honest with the poor dude you&amp;#039;re with.  Maybe he&amp;#039;ll step up his boyfriend game or maybe you&amp;#039;ll both decide to break up, but at least you won&amp;#039;t be burdening him with misery and yourself with guilt (and reduced fertility!) If you think your guy might be sneaking around, check out our handy guide to signs he&amp;#039;s not being faithful. Then get the hell outta there! Frankly, I just really hope Todd Akin doesn&amp;#039;t get a hold of this study or he&amp;#039;ll twist it to back up his claim that women&amp;#039;s bodies have ways to &amp;quot;shut that whole thing down.&amp;quot; Ugh.
