New Dads Get Post Natal Hormone Rush Too - Or Is It Just 'Stress'?

It's generally thought that only mum gets the rush of hormones post delivery which make her bond with her baby and produce milk, but new research has suggested that dads do too.

Research carried out at the Bar-Ilan University in Israel found that new dads experienced a surge in oxytocin and prolactin (which is usually the 'milk' hormone) in the six months after the arrival of their first baby.

The university's researcher, Professor Ruth Feldman said: 'This seems to be evolution's way of helping men turn into good parents as soon as they have a baby. These hormones seem to have a powerful role in helping men bond with their newly-born children.'

She added: 'It is possible that, as the father's daily encounters with his infant increase the prolactin and oxytocin systems reorganise and create new connections.'

UK medics however, are not so convinced. Dr Michael Craig from King's College London, commented: 'Oxytocin is also known to rise in response to elevated levels of stress, so this could also be part of the explanation.'
