The scent of women's tears also had a physical effect on men. There was less blood flow to areas of the brain related to sexual desire and the men showed low levels of testosterone. There were also signs of the absence of sexual arousal such as a slow heart rate and a slow breathing rate.
Interestingly, women are commonly sufferers of chronic dry eye. Is this evolution's way of suppressing "repulsive" tears to ensure successful mating? Just a thought.
