Pour les non-anglophones, les larmes de femmes pourraient avoir comme effet sur les hommes :
-Baisse de la libido
-Baisse de la testosterone
Le tout corrobore par des dosages biologiques et des donnees de l'imagerie du cerveau.

Abstract
Emotional tearing is a poorly understood behavior that is considered uniquely human. In mice, tears serve as a chemosignal. We therefore hypothesized that human tears may similarly serve a chemosignaling function. We found that merely sniffing negative-emotion-related odorless tears obtained from women donors, induced reductions in sexual appeal attributed by men to pictures of women's faces. Moreover, after sniffing such tears, men experienced reduced self-rated sexual arousal, reduced physiological measures of arousal, and reduced levels of testosterone. Finally, functional magnetic resonance imaging revealed that sniffing women's tears selectively reduced activity in brain-substrates of sexual arousal in men.
