'Cuddle Spray' Makes Men Girly Hormone induces emotion, empathy By Emily Rauhala, Newser User Posted Apr 30, 2010 3:36 AM CDT Updated May 2, 2010 5:45 PM CDT 41 comments Comments He doesn't want to be a macho, macho man. (Shutter Stock) (Newser) – Watch out macho men: German researchers have found a way to make males more sensitive. A hormone-laced potion called "cuddle spray" shot into men's noses can make males more emotional, empathetic and snugly. The active ingredient is oxytocin, a so-called "trust hormone" that is released during orgasm and childbirth. The sprays are already available online. The research, published in the Journal of Neuroscience, compared how men reacted to images of crying children, a grieving man and a girl with a cat. Participants whose noses had been sprayed with oxtytocin expressed levels of empathy typical of women. Those without the spray did not. This is the first study to show the chemicals' link to empathy, the Telegraph notes.
