We produce tears in response to insults to the eyes — ____1____, 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 ____2____ effects on men. The work appears in the journal Science.
The researchers knew that mouse tears contain pheromones that ____3____ other mice. So they looked for similar kinds of signals in human tears.
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 ____4____. But the men’s own body chemistry could tell the difference.
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 ____2____ arousal after smelling emotional tears ____5____ saline. Future studies will look at men’s tears, once researchers have collected enough videos of heartbreaking losses in big football games.

女性眼泪中的内容物会减少男人的性唤起 当眼中进入异物时我们就会流泪——洋葱的气味会薰痛双眼，小昆虫飞进眼角膜也会刺激泪腺。不过，当我们情绪激动时也会流下泪水，而且我们早就知道，这种充满感情的泪水，就化学形式而言，与眼睛受到刺激而流的泪完全不同。如今，以色列魏茨曼科学研究所的研究人员发现，女人们充满感情的眼泪明显会对男人产生生理影响。这一研究发表在《科学》杂志上。 研究人员知道老鼠眼泪中含有的信息激素会给其他老鼠传递信息。因此，他们在人类的眼泪中也寻找着类似的信号。 两名妇女自愿观看一部悲情电影，让科研人员收集她们的眼泪。然后，科研人员要求24名男子闻这些收集到的眼泪及生理盐水。这些男人指出，这两种含盐液体的样本并没有特殊气味。不过，他们体内的化学反应却能识别出两者的不同。 当男人们在嗅过眼泪之后看一些情绪中立的女性面孔的照片时，他们称这些女性脸孔的性吸引力更少。这些男人在闻过充满感情的泪水之后，同闻过生理盐水相比，其体内的睾酮激素更少，生理唤起的水平也较低。今后将侧重于研究男人的眼泪——只要研究人员能够收集到足够多的大型足球比赛中令人心碎不已的失球瞬间的录像。
