There is no fixed value for cervical ripeness. Cervical ripeness is often assessed by cervical Bishop’s score, which consists of five aspects: cervical rigidity, opening of the uterine opening, position of the fetal head, position of the uterine opening, and regression of the cervical canal. The success rate for a score of 4-6 is 50%, for a score of 7-9 is 80%, and a score of more than 9 is basically a success, and the higher the score, the better the ripeness, and the higher the success rate. It is important to note that a normal labor does not depend solely on cervical ripeness, but also on the condition of the birth canal, the size of the fetus, and the force of delivery. If a pregnant woman has a need for a normal delivery, she should be thoroughly evaluated by a medical professional to avoid a blind vaginal trial of labor, which may lead to an adverse outcome of the pregnancy.
