GERMANY (WIFR) -- Scientists say a naturally-produced hormone might make men less likely to cheat on their partners.
German researchers found that men in relationships that were given the hormone oxytocin were more likely to want to stay further away from an attractive unknown woman.
Previous studies have shown that oxytocin creates a stronger bond between parents and children and even couples.
Some scientists say it may be what helps us stay in monogamous relationships.
