A team of researchers from the Weizmann Institute of Science has found that tears turn men off and published results of the study in the journal Science. Biochemist Idan Frumin led a study into the effect of tears on people. The team collected tears samples after women viewed films like "Life Is Beautiful," "Terms of Endearment," "When A Man Loves A Woman," "My Sister's Keeper," and "Broken Wings." Researchers then had men smell the tears and view pictures of women's faces then follow up with answering a questionaire. One of the questions posed: "What is the state of sexual arousal of this specific subject in this specific moment?" Researchers found arousal dropped significantly following the men's sniff of the cup of tears.
Further studies found that testosterone levels dropped and brain sections which process sexual arousal diminished after men smelled the tears but no changes occurred upon smelling cups of salt water.
Psychologist Thomas Cleland from Cornell University praised the study with "It's probably the best study yet showing that chemical communications between humans is a reality."
