A new study has suggested that love hormone, oxytocin, does not only make you love people, but also racist and nepotistic. The study helped professor of psychology at the University Of Amsterdam Carsten De Dreu to understand that oxytocin also extends in-group favoritism.

You feel loved-up when you have lots of oxytocin released in your body, but it also extends to your in-group favoritism and derogation of outsiders. He added that love hormone had a role to play in the emergence of intergroup conflict and violence.

Love hormone is also released by the popular party drug Molly, also known as Ecstasy or MDMA. All participants in the study were Dutch males and they were asked to choose five persons out of six to gain access to a life-saving lifeboat. The men who had oxytocin had higher likelihood to deny the access for men with Muslim or German-sounding names, but they allowed the access to men with Dutch names.

On the other hand, men who were given a placebo were found to give no attention to the origin of the names. This led the professor to a conclusion that oxytocin is not as touchy-feely as previously thought

Apart from making you racist and nepotistic, a dose of love hormone can also make your orgasm more intense. It was found by another study that taking oxytocin before sex leads to more intense orgasms. Also, it provides a feeling of greater levels of contentment after sex. The dose of oxytocin works better in men.

"This field study demonstrates that oxytocin may alter specific aspects of sexual experience and partner interactions in healthy couples", said the researchers, from Hannover Medical School in Germany.

The researchers, however, said that further researches are needed to confirm the findings as the study was small and included adults who had no sexual problems.
