What is interesting is that saying men have post-natal depression severs the link with biology.

Ellie Lee还提到，有趣的是，男性的“产后抑郁”也是具有生物性的。

Post-natal depression affects around 25 percent of women, but little is known about the condition in men.

约有25%的女性患有产后抑郁症，然而男性的情况则始终备受忽视。

Sleep deprivation, which can continue well past an infant's first birthday, is a major contributor to post-natal depression.

睡眠剥夺将一直持续到婴儿周岁后，是造成产后忧郁症的主要原因之一。
