Study: Pretty Women Boost Men's Libido

According to a study by researchers at the University of California, men get a biological lift by spending time with pretty women. Specifically, men were found to enjoy a temporary boost in testosterone and cortisol, both of which are associated with alertness. The research apparently did not address the anecdotal evidence of men experiencing a temporary muscle stiffness brought on by spending time with pretty women.

Reportedly, the study's results actually replicate the hormonal increase found in animals known as the "mating response."

[The researchers] recruited 149 male students aged between 18 and 24 with a third interacting with a male researcher of 25 and the others talking to one of seven young female undergraduates aged 18 to 22.

After the short five minute sessions the men were asked to rate the physical attractiveness of the women between one and seven. The average was 5.83 showing they found them alluring.

The participants then swished with mouthwash before providing a sample of saliva into a collection vial which was tested within 20 to 40 minutes of exposure to the women.

Psychologists found that just a five minute talk with an attractive women raised the levels of testosterone by 14 per cent and the anti-stress hormone cortisol by 48 per cent.

Understandably, the level of testosterone and cortisol decreased in men who spent time with other men, apparently despite how pretty they were.

In any event, some people might question the need for such research since the results are predictably obvious. Men with hot babes produces elevated testosterone. Duh.

Incidentally, a similar study in August found that hot cars increase testosterone levels in men. Again -- Duh!
