It has proved biologically that why men dislike women's tears.... when the weeping tears are sniffed by a man these little emotions in the form of water droplets can depress men's libido. When a woman cry its cause men to produce less testosterone ,which depress or dull their sexual desire like a cold shower and can cause women's face feels to them less arousing . It's not unique to women's but it was first time studied. The water flow from eye due to dust n emotional tears are chemically very different. It has been tested in a lab by Dr. Noam Sobel and his researchers AT Weizmann Institute of Science in Rehovot, Israel, they collected the tears of a lady, and than for a comparison trickled saline down the women's cheeks and collected those droplets, too... A healthy man couldn't smell a difference between the real tears and the saline water ,then they experiment by giving man the photographs of women .When they sniffed actual tears they found women less sexually attractive but when they sniffed saline it has less impact.. and saliva tests of testosterone levels found a regression in the hormones and brain activity also reduce after they sniffed tears but not the salt water..
Dr. Noam Sobel, said “ women cry much more during menstruation, and from a biological standpoint that is not a very effective time to have sex, so reducing sexual arousal in your mate at that time is really convenient,”
Female tears contain a chemical that makes her less attractive to the opposite sex, because women’s emotional tears contain a chemical called chemosignal that reduces sexual arousal in men,”
