Why crying is good for your health

Several factors play a role in an individual's propensity to cry. ... Biologically, there may be a reason women cry more than men: Testosterone may inhibit crying, while the hormone prolactin (seen in higher levels in women) may promote it.We show an association of long-term testosterone levels with increased emotional reactivity in the brain. These results suggest a heightened emotional vigilance in individuals with high trait testosterone levels.
