Experts are claiming that some women don't feel any pain at all during childbirth, due to a rare gene. According to researchers from Cambridge University around one in 100 women have a rare variant of the gene KCNG4, which is associated with a higher pain threshold. This variant means they don't require pain relief when giving birth, as it acts "like a natural epidural". From this they found that the women who had not required pain relief showed higher tolerance for heat, cold and mechanical pressure, as well as pain. The rare variant found is said to reduce the ability to open the gate and turn on nerves.
