Scent of a woman
men’s testosterone responses to olfactory ovulation cues
From Psychological Science
According to this research, odors can be a subtle factor affecting human mating, similar to the behavior of other animals. Monitoring the responses of men after smelling t-shirts worn by ovulating women, non-ovulating women and some not worn at all, they observed reactions and biological changes. This study provides evidence that ovulatory cues are detectable, the findings suggest that smell can be identified as a relatively subtle biological process that guides mating and can be linked to sexual behavior and initiation of romantic courtship.
