2005蘇黎世大學(Zurich University)費爾(Ernst Fehr)團隊進行研究時，要求受測者參與「信任遊戲」，同時使用功能性磁振造影術掃描他們的腦部。學者發現，催產素會抑制腦部兩個原本充當天然「防衛牆」之區域的活動。

Seeking a healthy boost to kick start your day?
Look no further than the bedroom.
Dr Debby Herbenick, an American research scientist and sex advice columnist,
said: ‘Having sex in the morning releases the feel-good chemical oxytocin, which makes couples feel loving and bonded all day long.’
Adults who make love first thing in the morning apparently not only feel more upbeat for the rest of the day,
but also benefit from a stronger immune system.
Research suggests that adults who begin their day this way are healthier
and happier than those who simply opt for a cup of tea and some toast before heading out of the door.
Not only does it make them less likely to catch a cold or flu, it can also improve the quality of their hair, skin, and nails.
Sex releases the hormone and will create a bond between the two people involved. Since the release of oxytocin can be classically conditioned, after repeatedly having sex with the same partner, just seeing that partner could release more oxytocin, making you want to be with that person all the more.
Breaking this bond is often difficult and can lead to depression and other psychological woes.
The world today promotes the notion that sex is pure recreation, that the “hook-up” culture is natural and even empowering to women, and that love and sex are two completely different things.
That’s not the whole story. Casual sex is not a natural part of the human make-up. Sex is a bonding experience and when the bond is broken by multiple partners, your body and mind have a conflict. This conflict is caused by a hormone called oxytocin and this is what makes love so ecstatic but also hurt.
Remaining sexually pure until marriage is the way the human body was designed. To be with and desire one person in your life time is part of the human chemical make up. Stepping outside of that natural design creates conflict between body and mind.
The hormone Oxytocin comes from a Greek word meaning “quick birth”. It is a mammalian hormone that also acts as a neurotransmitter in the brain. In women, it is released mainly after distension of the cervix and vagina during labor, and after stimulation of the nipples, facilitating birth and breastfeeding. Oxytocin is also released during orgasm in both sexes. In the brain, oxytocin is involved in social recognition and bonding, and is involved in the formation of trust between people.
