[Cervical ripening and labor induction].

To induce labour successfully, a good cervical status and favorable obstetrical conditions are necessary. If these conditions are not present, cervical ripening must take place before induction of labour. Cervical ripening is only justified when a pathology (maternal or foetal) indicates termination of pregnancy. Intracervical or intravaginal administration of prostaglandin E2 is actually the standard for cervical ripening.
