研究:避孕药会收缩大脑中控制性欲的部分

The pill shrinks the part of the brain that controls your sex drive, according to new research.

根据一项新的研究，避孕药会收缩大脑中控制性欲的部分。

Top scientists found that women taking the contraceptive pill have a significantly smaller hypothalamus – a brain region responsible for regulating hormones.

顶级科学家发现，服用避孕药的女性的下丘脑要小得多，下丘脑是大脑中负责调节荷尔蒙的区域。

Damage to the hypothalamus can wreak havoc with a women’s sex drive, mood, appetite, heart rate and sleep cycles.

对下丘脑的损害会严重影响女性的性欲、情绪、食欲、心率和睡眠周期。

The shocking revelation comes following a study, presented at the annual meeting of Radiological Society of North America, that examined 50 women – 21 of whom were using the Pill.

在北美放射学会年会上公布的一项研究得出了这一令人震惊的结论，该研究调查了50名妇女，其中21名正在服用避孕药。

All 50 women underwent a brain scan, and doctors measured the size of the hypothalamus of each participant.

所有50名女性都接受了脑部扫描，医生测量了每位参与者的下丘脑的大小。

And doctors were stunned to discover the difference in brain structures in women taking the Pill compared to those who weren’t.

医生们惊讶地发现，服用避孕药的女性与未服用避孕药的女性在大脑结构上的差异。

Dr. Michael Lipton, professor of radiology at Albert Einstein College of Medicine in New York, said: “We found a dramatic difference in the size of the brain structures between women who were taking oral contraceptives and those who were not. This initial study shows a strong association and should motivate further investigation into the effects of oral contraceptives on brain structure and their potential impact on brain function.”

纽约阿尔伯特·爱因斯坦医学院的放射学教授迈克尔·利普顿博士说:“我们发现，服用口服避孕药的女性和未服用避孕药的女性在大脑结构大小上存在显著差异。这项初步研究表明，口服避孕药与大脑结构之间存在很强的相关性，这将促使人们进一步研究口服避孕药对大脑结构的影响及其对大脑功能的潜在影响。”

Dr. Lipton also found a strong correlation between smaller hypothalamic volume and greater anger and depressive symptoms.

利普顿博士还发现，下丘脑体积越小，越容易发怒和出现抑郁症状之间存在很强的相关性。

Despite this, he said that this finding was currently “preliminary”. This is the first time structural effects of sex hormones, including oral contraceptive pills, on the human hypothalamus have been reported, according to the researchers.

尽管如此，他说这个发现目前只是“初步的”。据研究人员介绍，这是包括口服避孕药在内的性激素首次对人类下丘脑产生结构性影响。

It comes after it was revealed the Pill can dictate who you fall in love with and significantly lower your sex drive.

此前有研究表明，避孕药可以决定你爱上谁，并显著降低你的性欲。

Top psychologist Dr. Sarah Hill revealed that it affects “sex, attraction, stress, hunger, eating patterns, emotion regulation, friendships, aggression, mood, learning, and so many other things”.

顶级心理学家萨拉·希尔博士透露，它会影响“性、吸引力、压力、饥饿、饮食模式、情绪调节、友谊、攻击性、情绪、学习以及许多其他事情”。

She said women on the Pill are attracted to less masculine men and are less interested in sex.

她说，服用避孕药的女性会被不那么阳刚的男性所吸引，对性也不那么感兴趣。

That’s because the hormone progesterone, which sends a message to the body that ovulation is not required, is dominant throughout your cycle.

这是因为荷尔蒙黄体酮在你的整个周期中处于主导地位，它向身体传递一个信息:排卵是不需要的。

She said: “Rather than experiencing an increased preference for sexy men at high fertility like naturally cycling women do, Pill-taking women exhibit an unwavering preference for men with less masculine faces and voices.

她说:“与自然循环的女性对高生育能力的性感男性的偏好不同，服用避孕药的女性对面容和声音不那么男性化的男性有着坚定的偏好。”

“This is the sort preferred by naturally cycling women during the second half of their cycles, when progesterone is high.”

“这是自然循环的女性在生理周期的后半段，也就是黄体酮含量高的时候所喜欢的。”

Earlier this year, experts warned that one million women could be taking the wrong contraceptive pill – and could be suffering nasty side effects in silence.

今年早些时候，专家们警告说，有100万女性可能服用了错误的避孕药，而且可能默默承受着严重的副作用。
