Marmosets are small primates.

Think of a monkey with huge fuzzy ears.
想象一只有巨大、毛绒绒耳朵的猴子。
Primatologists have often wondered whether nonhuman males evaluated their potential mates,or whether their sex drive was more like an on/off switch.
动物学家时常困惑：雄性动物选择“另一半”或者控制性欲是否更像是一个开关键。
We may think of animals as just responding to sexual invitations without thinking, but a study conducted in both the U.S. and Germany shows this isn't necessarily so.
我们可能认为动物只是不假思索地对性邀请做出反应，但美国和德国的一项研究表明，事实并非如此。
Male marmosets having their brains scanned were given sniffs of genital-gland secretions from ovulating females.
雄性绒猴开始用大脑扫描，嗅着正在排卵的雌性动物生殖腺的分泌物。
That's a scent that should trigger a mating response in the brain, and it did!
这种气味会引起大脑里的交配反应，这样它们才会进行交配。
But guess what else happened?
但你猜还会发生什么情况?
