How do tears affect men
Sources:
Tears have a significant physiological impact on men, particularly through their influence on testosterone levels. When men sniff women's tears, even though the tears are odorless, there is a pronounced reduction in testosterone levels. Specifically, research has shown that sniffing these tears can lead to about a 14% drop in free testosterone within 20 to 30 minutes. This reduction in testosterone can also influence brain activity and lower aggression in men 1 2.
