"We certainly don't want to put a message out there on the lines of 'pregnancy makes you lose your brain,' as we don't believe this is the case," said Elseline Hoekzema, a researcher at Leiden University in the Netherlands, who led the study at the Universitat Autonoma de Barcelona in Spain.

"我们肯定不想发出'怀孕让你变傻'这样的信息，因为我们不觉得情况是这样的，"荷兰莱顿大学的研究员埃尔斯利娜·赫克泽马说道。她领导了在西班牙巴塞罗那自治大学进行的这项研究。

Pregnancy, she explained, may help a woman's brain specialize in "a mother's ability to recognize the needs of her infant, to recognize social threats or to promote mother-infant bonding."

她解释说，怀孕有助于女性的大脑专注于培养"一个母亲意识到婴儿的需求，意识到社会威胁，以及拉近母婴关系的能力"。

The researchers also scanned the brains of 17 men who were not fathers and 19 first-time fathers before and after their partners' pregnancies. The two male groups showed no difference in brain volume.

研究人员也扫描了17名没有做过父亲的男子的大脑，和19位首次为人父的男子的大脑——在他们的伴侣怀孕前后各扫描了一次。结果显示，这两组人的脑容量并无差异。
