Rare Gene Could Be Why Some Women Have Less Childbirth Pain, Say Scientists
Women who do not require pain relief during childbirth might have a rare genetic variant, according to scientists.
Researchers at the University of Cambridge found that the variant plays a role in reducing the ability of nerve cells to send pain signals to the brain.
