Women's Tear Contents Lessen Men's Sexual Arousal

女性眼淚中的內(nèi)容物會(huì)減少男人的性喚起

We produce tears in response to insults to the eyes — the sting of onion fumes, a tiny insect that flew into your cornea. But we also produce emotional tears. And it’s long been known that emotional tears are chemically different from poke-in-the-eye tears. Now researchers at the Weizmann Institute of Science in Israel find that women’s emotional tears have definite physiological effects on men. The work appears in the journal Science.

當(dāng)眼中進(jìn)入異物時(shí)我們就會(huì)流淚——洋蔥的氣味會(huì)薰痛雙眼，小昆蟲飛進(jìn)眼角膜也會(huì)刺激淚腺。不過，當(dāng)我們情緒激動(dòng)時(shí)也會(huì)流下淚水，而且我們?cè)缇椭?，這種充滿感情的淚水，就化學(xué)形式而言，與眼睛受到刺激而流的淚完全不同。如今，以色列魏茨曼科學(xué)研究所的研究人員發(fā)現(xiàn)，女人們充滿感情的眼淚明顯會(huì)對(duì)男人產(chǎn)生生理影響。這一研究發(fā)表在《科學(xué)》雜志上。

The researchers knew that mouse tears contain pheromones that convey information to other mice. So they looked for similar kinds of signals in human tears.

研究人員知道老鼠眼淚中含有的信息激素會(huì)給其他老鼠傳遞信息。因此，他們?cè)谌祟惖难蹨I中也尋找著類似的信號(hào)。

Two women volunteered to watch sad movies and have their tears collected. Twenty-four men were then asked to sniff the movie tears or a saline solution. The men noted no particular smell in either sample of salty water. But the men’s own body chemistry could tell the difference.

兩名婦女自愿觀看一部悲情電影，讓科研人員收集她們的眼淚。然后，科研人員要求24名男子聞這些收集到的眼淚及生理鹽水。這些男人指出，這兩種含鹽液體的樣本并沒有特殊氣味。不過，他們體內(nèi)的化學(xué)反應(yīng)卻能識(shí)別出兩者的不同。

When the men looked at emotionally neutral images of women’s faces after sniffing real tears, they reported less sexual attraction. The men also had lower levels of testosterone and less physiological arousal after smelling emotional tears compared with saline. Future studies will look at men’s tears, once researchers have collected enough videos of heartbreaking losses in big football games.

當(dāng)男人們?cè)谛徇^眼淚之后看一些情緒中立的女性面孔的照片時(shí)，他們稱這些女性臉孔的性吸引力更少。這些男人在聞過充滿感情的淚水之后，同聞過生理鹽水相比，其體內(nèi)的睪酮激素更少，生理喚起的水平也較低。今后將側(cè)重于研究男人的眼淚，只要研究人員能夠收集到足夠多的大型足球比賽中令人心碎不已的失球瞬間的錄像。
