“Hello! I’m Professor Sarah Tonin, and I’m going to tell you a little story about the science of love.
There are three key stages to falling in love. The first is lust – which is primarily driven by the sex hormone testosterone. The second stage is attraction – where you begin to focus all of your attention on your partner. The third and final stage is attachment – where your body and mind make a longer lasting bond to your partner

“Androgens such as testosterone are central to sex drive in both men and women. And it’s this sex drive that leads us to go out and look for love in the first place. But testosterone doesn’t act alone in this; a balance of social circumstances and experiences, oestrogen and other bodily systems determine when, where and how often someone feels lust. So what about attraction?”
