Men smelling women: null effects of exposure to ovulatory sweat on men's testosterone.

Although participants did not differentially detect human stimuli across the two conditions, there was evidence that they were more likely to detect odors in general in the sweat condition: participants reported having smelled nothing in 41 percent of the control sessions but in only 22 percent of the experimental sessions; a binary mixed logistic regression model revealed a marginally significant, within-subject effect of experimental condition on the likelihood of having reported detection of any scent ( b = 1.13, p = 0.067, Exp ( b ) = 3.10).
