Scientists create spray to make men more sensitive

April 29, 2010 Researchers explain the spray uses the hormone oxytocin, which is called the "cuddle chemical" because it stimulates affectionate feelings in humans.

In the experiments, 24 men took nasal sprays containing oxytocin, while 24 others were given a placebo. Afterwards they were shown emotional photographs including a crying child and a man in mourning. Researchers explain the men who were given oxytocin showed higher emotional empathy levels than those on the placebo.

The study is published in the Journal of Neuroscience.
