“梨花帶雨”會令男性興趣大減

Israel scientists claimed that the scent of a woman's tears is a major turn-off for men. Men who sniffed real tears became less sexually aroused than those who sniffed saline, according to the researchers from the Weizmann Institute of Science and Edith Wolfson Medical Center in Israel。

In the study, two women ageing 30 and 31 watched sad movies by themselves and placed vials beneath their eyes to collect teardrops. Their tears were collected one milliliter at a time and deposited onto small pads that were attached beneath men's noses, so they could continuously sniff the sadness。

Then 24 male participants, whose mean age was 27, were shown emotionally ambiguous photographs of women and asked to rate the faces' sadness and their attractiveness. The faces appeared less sexually attractive after sniffing real tears, according to the study. The researchers also learned the men experienced a drop in testosterone。

As a matter of fact, Israel scientists have expected tears' chemical signals to trigger empathy or sadness, but that didn't happen - women's tears just dampen men's sexual desire. Some researchers believe this phenomenon evolved to protect emotionally vulnerable women from male aggression。據美國“大衆科學”網7日報道，以色列科學家日前宣稱，女人眼淚的味道會讓男性興趣大減。據以色列魏茨曼科學研究所以及伊迪斯•沃爾芬森醫學中心的研究人員稱，與嗅過鹽水的男性相比，聞到了真實眼淚味道的男性慾望有所降低。

在研究中，兩名年齡分別爲30、31歲的女子各自觀看悲情電影，同時將藥水瓶置於眼睛下方以收集眼淚。每當眼淚聚滿1毫升後研究人員便將其滴入小墊並放置在男性鼻子下端，這樣他們可以持續地嗅到“悲傷的味道”。

然後24名平均年齡爲27歲的男性受試者，被要求在觀看一組表情不明確的女性照片後，按照面孔的悲傷程度和吸引力對照片進行排名。研究發現，男性聞過眼淚的味道後，這些面孔在他們眼中就變得不那麼有吸引力了。研究人員也瞭解到(聞過眼淚味道的)男性體內睾丸激素有所下降。

事實上，以色列科學家本來預期眼淚中的化學物質能夠引發同情或者悲傷心理，然而事與願違——女人的眼淚只是起到了抑制男人性慾的作用。一些研究人員認爲這種進化結果乃是爲了保護情感脆弱的女性不受男性的攻擊。
