Inject your guy with 'cuddle hormone' and he may never stray

Before you say "I do," you may want to stock up on oxytocin. The cuddle hormone that helps moms bond with babies and promotes lactation could be the key to keeping attached men on the straight and narrow. A study of 86 heterosexual men kept tabs on their responses when an attractive woman approached. The results, published in the Journal of Neuroscience, showed that men who'd had a dose of oxytocin and were in a relationship preferred to be further away from the bait than those who hadn't. So if you know a guy who's got a wandering eye, this may be the perfect X-mas gift — for his mate. [Source]
