Young men injected with the hormone and then given brain scans showed a flurry of activity in the parts of the brain activated by sexual arousal and romance.

Professor Waljit Dhillo, the lead author of the research from Imperial College London, said: 'Our initial findings are novel and exciting as they indicate that kisspeptin plays a role in stimulating some of the emotions and responses that lead to sex and reproduction.
该研究的首席作者、伦敦帝国学院的沃尔吉特•迪洛教授说：“初期研究结果显示，kisspeptin能激起导致性行为和生育的一些情感和反应，这一发现新奇又令人振奋。
'Ultimately, we are keen to look into whether kisspeptin could be an effective treatment for psychosexual disorders, and potentially help countless couples who struggle to conceive.'

Those injected with kisspeptin, discovered in the mid-1990s in Hershey, Pennsylvania, and named after sweets from the city called Hershey's Chocolate Kisses, reacted differently to sexual and non-sexual romantic pictures of couples.

In an MRI scanner, where their brains were monitored, there was greater activity in the parts of the brain typically activated by sexual arousal and romance than the men given a placebo.
核磁共振扫描发现，被注射kisspeptin的男性大脑中会被性唤起和浪漫事物激活的部位比那些服用安慰剂的男性有更大幅度的活动。
The effect is likely to come from kisspeptin's role in starting puberty, by stimulating the release of reproductive hormones.
产生这一效果很可能是因为kisspeptin能够刺激生殖激素的释放，正如kisspeptin催动青春期时的作用一样。
