New York: In trying to understand how "female Viagra" will affect the brain of women users, researchers from the University of Wisconsin-Madison have found that when brain metabolism dipped in monkeys during tests, desire went up in them for popping "female Viagra".

The findings showed that the drug, called flibanserin, by altering metabolic brain activity prompts increased female behaviour responses to grooming (intimate, gentle touching from males) -- a discovery that "offers the first insight into how the drug may be working in the brains of women".
