A woman's tears will make you erectile dysfunction...

Tears, in addition to protecting the eyes, can also produce other chemical reactions in humans, such as Anti-Viagra (that is, it makes you flaccid).

Neurobiologist Noam Sobel from the Weizmann Institute of Science in Israel found in his research that: after males smelled the tears of females, their sexual arousal decreased and their testosterone levels dropped. Furthermore, when female brains were imaged using magnetic resonance imaging, it was discovered that the brain regions which usually respond to erotic stimuli (the hypothalamus and fusiform gyrus) became calm and stable.
