Testosterone may be associated with aggression but a new research claims the male hormone also drives social behaviour and honest interactions.
Researchers from the University of Bonn gave 46 people testosterone gel and 45 people a placebo. The next day, all 91 people were invited
to roll the dice in private, report the numbers they landed on, and receive money - with the higher rollers netting more cash.
After paying out the participants, the researchers found that men who received the testosterone gel self-reported their numbers more honestly, said researchers.
Researchers from Wayne State University also compared two groups of men competing to win the attention of an attractive woman and found that men with lower testosterone didn't even stand a chance.
Men with the highest testosterone levels were more assertive, controlled the conversation, and clicked better with women.
