It has other effects. It encourages pair bonding, and parental behaviour. It is released during intimate moments during orgasms and even hugs. For this reason it is often called the 'love hormone'.
Strange to say, the oxytocin released by the pituitary gland cannot reach the brain: it does have effects on the rest of the body. The reason is that there is a blood–brain barrier which prevents large molecules from getting into the brain. Instead, the hormone is produced by special nerve cells inside the brain.
