Men spritzed with oxytocin, a hormone from the pituitary gland, showed a renewed attraction for the faces of their romantic partners, but not for equally attractive strangers, according to [new study published] in the journal Proceedings of the National Academy of Sciences.
“Monogamy is actually quite costly for humans, so there must be some form of benefit,” said Rene Hurlemann, a psychiatrist at the University of Bonn in Germany who led the study. “We’d expect humans, especially males, would disseminate their genes. That would be a very strong evolutionary force driving male behavior. But what drives males to stay in a monogamous relationship?”
The answer may lie in a steady diet of oxytocin that triggers dopamine, a neurotransmitter associated with reward, motivation and addiction, according to the study.
In humans, overtures of social support, hugs, massages and sexual intercourse all release oxytocin. And oxytocin, in turn, has been shown to induce pro-social behavior –- we tend to trust each other and feel more attached to others in response to the chemical.

We tend to see gesticulation as a behavioral quirk, but research shows these hand movements actually assist our mental processes.
A study published last year found that people were better able to explain math problems and simultaneously remember a string of letters if they were allowed to gesture meaningfully as they spoke [because] gesturing probably makes the math part of the task less mentally taxing by externalizing and visualizing relevant information, thereby freeing up cognitive resources for the memory challenge.
As a bonus, gesturing while you speak won’t only aid your thought processes, it likely will also help you make a good impression. Research has shown that presenters are judged as more effective and competent when they make hand gestures compared with when they keep their hands still. Like tone, volume, and pacing of your speech, gestures are another tool to punctuate what you’re saying. Gestures can also help the audience understand and remember what you said. The key thing here is to ensure your gestures are meaningfully related to what you’re saying, and not just random hand flapping.
