The Fidelity Hormone

The fidelity hormone
Intriguing new research shows that a special hormone kicks in to stop men who are in committed relationships from getting "uncomfortably close" to other women.
Men in committed relationships choose to keep a greater distance between themselves and an unknown woman they find attractive when given the hormone oxytocin, according to research in The Journal of Neuroscience. The findings suggest oxytocin may help promote fidelity within monogamous relationships. Oxytocin plays a vital role in triggering childbirth and facilitating nursing. The hormone, which is produced in a region of the brain called the hypothalamus, is also involved in the formation of social bonds, bonds between parents and children, and between couples.
In the study, led by René Hurlemann, MD, PhD, of the University of Bonn, researchers found that heterosexual men in committed relationships who were given oxytocin via a nasal spray and introduced to a female that they later described as “attractive” kept a greater distance when approaching or being approached by her compared with those men given a placebo. They also reported that they felt “slightly uncomfortable” when she came closer than 10-50 centimetres away from them. In contrast, oxytocin had no effect on single men; nor did it have any effect on the distance men kept between themselves and male experimenter.
