Is infidelity genetic?
Research suggests that a hormone called oxytocin, which facilitates trust and allows people to form strong bonds, could be the key to whether or not a spouse strays.
A study published last year in the Journal of Neuroscience indicated that when men in committed relationships are given oxytocin, they stay physically further away from attractive women. Single men, and men in committed relationships who did not receive oxytocin, told researchers that they were comfortable standing at a closer distance to the women.
Kimberly Van Scoy with WXII 12 news recently interviewed Dr. Wiggy Saunders with Robinhood Integrative Health in Winston-Salem, N.C about these findings. Saunders said that low levels of oxytocin could lead a person to cheat.
