Testosterone for fun -- and profit

From Times Staff and Wire Reports

Testosterone, the hormone that drives male aggression and sexual interest, also seems able to boost short-term success at finance.

But elevated testosterone levels over several days could lead to irrational risk-taking, researchers at the University of Cambridge in England reported Tuesday in the Proceedings of the National Academy of Sciences.

The team studied male financial traders in London, taking saliva samples in the morning and evening. Those with higher levels of testosterone in the morning were more likely to make an unusually big profit that day.
