A recent research threw light on how the 'love hormone' oxytocin has been able to make males all the more faithful towards their partners. It has been claimed by German researchers that men who were given an oxytocinnasal spray managed to maintain a distance of some 4-6 inches from attractive women as compared to other men who received a placebo.

The team claimed that the 'Love hormone' makes men keep fidelity high. It was earlier that researchers had claimed that the same hormone has a key role to play in pair-bonding. "Previous animal research in prairie voles identified oxytocin as major key for monogamous fidelity in animals", said study researcher Rene Hurlemann of the University of Bonn in Germany, while asserting that the oxytocin may have a similar role for humans.

For the research, the team had recruited 86 heterosexual males and instructed randomly to take either oxytocin or a placebo with no effect. It is believed that Oxytocin instigates committed men to expand their personal "Don't come near me" bubble when they come close to any attractive woman. Apparently, the same hormone can make men less trustworthy of outsiders and is likely to make them feel uncomfortable in anyone's presence about them.
