Do low levels of oxytocin cause a person to become unfaithful (have an affair)?

In hearing Paul Zak's discussion on 'Trust, morality and oxytocin', I began to wonder if a person's relationship 'morals' decline with lower levels of oxytocin...and this seems funny to write.....could it be that this may be part of the reason people engage in extramarital affairs, particularly people in long term marriages when a spouse describes: boredom, lack of sparks, etc?

  • Nov 2 2011: I was wondering the same thing as I was watching the video. If low levels of oxytocin could be a contributing factor to unfaithfulness.

    Nov 3 2011: I wonder how one would feel if the other partner says:" ...Dear, this isnt working any more...you know...my level of oxytocin has dropped recently and i dont know it will come again or not...so let's divorce!"(in other words,blame on the my oxytocin not me!)

    That just dosent make sense to me neither do boredom and lack of sparks.

    Nov 3 2011: Straight from Wikipedia:

    "Bonding. In the Prairie Vole, oxytocin released into the brain of the female during sexual activity is important for forming a monogamous pair bond with her sexual partner. Vasopressin appears to have a similar effect in males.[48] Oxytocin has a role in social behaviors in many species, and so it seems likely that it also does in humans. In 2003, a study showed that in both humans and dogs oxytocin levels in the blood rose after five to twenty-four minutes of a petting session. It is possible that this plays a role in the emotional bonding between humans and dogs.[49]"

    Nov 2 2011: Maybe not, since it's a social endorphine, and the trueness of the values is validated in the greater text of the culture, which can have contradictory sayings about values, such as fidelity, sharing or other things, and thus being moral is not a static and unique way of being.
