He might think he is being helpful as he holds your hand while you are in the throes of labour, but he could actually be making the pain far worse.
Research suggests that women who lack emotional intimacy with their partner feel more pain if he is with her.
The study, by University College London, King's College London and the University of Hertfordshire, found the pain felt by 39 women given "pinprick" laser pulses on their fingers was not reduced by the presence of their partner and, in many cases, it worsened the pain for women who most avoided closeness in their relationships.
The presence of men at a baby's birth has always divided opinion, but has grown in popularity since home births began to decline in the 70s. Previous studies had found that women in labour needed fewer painkillers if their partner was present.
In the new experiments, women were given a moderately painful laser pulse on a finger and asked to rate the pain's intensity. Researchers also measured how the electrical activity in their brains "spiked" in response to the laser pulses. Each woman then completed a questionnaire to measure the extent to which she either sought or avoided "closeness", or emotional intimacy, in relationships.
