'Love Hormone' May Trigger Jealousy, Too
SUNDAY, Nov. 15 (HealthDay News) -- With a reputation as the "love hormone," oxytocin has been linked to trust, empathy and generosity.
But new research suggests that oxytocin plays a role in jealousy and gloating as well.
"Subsequent to these findings, we assume that the hormone is an overall trigger for social sentiments: When the person's association is positive, oxytocin bolsters pro-social behaviors; when the association is negative, the hormone increases negative sentiments," Israeli researcher Simone Shamay-Tsoory, of the University of Haifa, said in a news release from the university.
Scientists have linked the hormone to feeling good. It's released during childbirth and when people have sex. Research has found that people who inhaled a man-made form of the hormone were more altruistic.
But in earlier research, Shamay-Tsoory had discovered that mice who inhaled oxytocin were more aggressive so she decided to figure out if the hormone might have the same effect on people.
To do that, she had 56 people inhale a man-made version of the hormone or a placebo. They then played game designed to encourage feelings of envy and gloating.

This is fascinating; I've read about the hormone vasopressin playing a role in jealousy but not oxytocin. I guess it makes some sense though...it plays a role in attachment, and if you become attached to someone you're a lot more likely to be jealous if someone (or something) else becomes the focus of their attention...
Here's a link to the original journal article if anyone wants to read about it in more detail:
