Women might want to think twice before spritzing Chanel No. 5. A new study suggests that a woman's natural scent may be all she needs.
Recent research shows that a man's testosterone levels, which are linked with sexual interest, are significantly higher when they smell the shirt of a woman who is ovulating.
Other studies have linked higher levels of testosterone with an increase in sexual arousal as well.
In surveys, men have reported being more attracted to ovulating women. The new study builds on this research by measuring the response of men to a specific chemical cue.
