weak cervix

A lawyer who struggled to have a baby for seven years has now given birth to a healthy little girl after being fitted with a 'bionic' cervix. Janett Walker, 41, suffered four miscarriages and lost a premature baby because her cervix was too weak to support an unborn baby.
Doctors 'clamped' the neck of her uterus using a synthetic material called mersilene, to stop a foetus from falling through.
