Action women and car

To test the theory that high-performance cars get people hot, Moxon had 40 men and women listen to recordings of the three Italian exotics and a Volkswagen Polo. Everyone had significantly more testosterone after hearing the exotics, and all of the women were turned on by the Maserati. The guys, on the other hand, were drawn to the Lamborghini.
"We saw significant peaks in the amount of testosterone in the body, particularly in women," Maxon says, noting that even women who said they had no interest in cars were turned on. "Testosterone is indicative of positive arousal in the human body so we can confidently conclude from the results out today that the roar of a luxury car engine actually does cause a primeval physiological response."

Wait a minute -- testosterone is what makes a person turned on?
