Women's periods do not synchronize if they live together, a new study claims.
一项最新研究指出，女性同居并不会使得她们的生理周期趋同。
Scientists have been examining the baffling phenomenon ever since a 1971 study showed female college roommates inexplicably ended up with the same menstrual cycle.
1971年的一份研究指出，某大学寝室一群女生莫名其妙地同时结束了生理周期，自那以后，科学家们一直在研究这个令人费解的现象。
The lead researcher Martha McClintock concluded women give off pheromones that influence other women's hormones.
当时那项研究的首席研究员玛莎·迈克林塔克得出结论称，女性会释放出影响其他女性荷尔蒙的信息素。
But according to research by the University of Oxford, the whole idea - also known as 'the McClintock effect' - is nothing more than a myth.
但是根据牛津大学的一项最新研究显示，整个观念（亦被称之为“麦克林托克”效应）纯属虚构。

Researchers collaborated with the period-tracking app Clue to analyze data on 1,500 women who responded to a survey, the Guardian reports.
《卫报》报道称，研究人员们与生理期追踪软件Clue进行了合作，分析了1500名女性参与某项调查时的数据。
They honed in on 360 women who regularly used the app, do not use hormonal birth control, and have a close relationship with another woman who they see regularly.
他们重点关注了其中360名女性，她们定期使用该软件，从不使用激素避孕药，还和另一个经常见面的女性保持亲密关系。
Following three menstrual cycles, the researchers concluded that the majority of participants (273) actually saw their cycles become more distanced from their close female friend.
在跟踪过三次生理期之后，研究人员得出结论称，大多数参与者（273人）的生理期事实上和她们闺蜜的生理期隔得越来越远。
Only 79 pairs experienced the mythical syncing phenomenon.
只有79对研究对象经历了神奇的生理期同步现象。
And there was no clear correlation between menstrual cycles and living together. The findings are hardly groundbreaking. Few studies have been able to reach the same conclusion as the 1971 investigation by Martha McClintock at Wellesley College.
而且生理周期和同居也没有明显的相关性。这些研究并没有什么突破性。很少有研究能够得出和1971年麦克林托克在韦尔斯利学院调查所得出的一样结果。
In fact, even McClintock's former colleague, psychologist Jeffrey Schank who now works at the University of California, Davis, has since found flaws in their own methods.
事实上，就连麦克林托克以前的同事、心理学家杰佛里·尚克（他现在任教于加州大学戴维斯分校）自那以后也发现了他们研究方法中存在的缺陷。
In a highly-controlled pheromone study on rodents, Schank found that the idea of these two pheromones communicating and influencing one another does not work.
杰佛里发现，在一项对啮齿动物高度控制的信息素研究中，认为两种信息素会互相交流并互相影响是不正确的。
