An end to infidelity?

  • Oxytocin may help men remain faithful in relationships
  • Men given oxytocin nasal spray kept a greater distance from attractive women
An end to infidelity?

A new study shows a naturally occurring hormone may keep men from cheating.
The hormone oxytocin was first recognized for its role in triggering uterine contractions during labor.  It later earned the nickname “love hormone” for its role in promoting attachment between parents and their children -- and reducing conflict between couples.  

But according to a new study conducted at Bonn University in Germany, it may also help men remain faithful in relationships. 

The study, set to be published in The Journal of Neuroscience, involved 86 men classified by researchers as healthy and heterosexual, PsychCentral reported.  When the men were given a dose of oxytocin nasal spray, they kept a greater distance from attractive women they did not know.  The distance ranged anywhere from four to six inches.  Men receiving placebo did not consistently maintain distance from the women. 

Dr. Rene Hurlemann, M.D., Ph.D., of the University of Bonn explained, "Previous animal research in prairie voles identified oxytocin as major key for monogamous fidelity in animals.  Here, we provide the first evidence that oxytocin may have a similar role for humans," the Huffington Post mentioned.

However, researchers admit that increasing oxytocin in humans to achieve such effects has yet to be determined.
