A long cervix generally has no special effect on labor.
The cervix belongs to the soft birth canal, the cervical canal is 2-3cm long before labor, the regular contractions after labor will pull the uterine muscle fibers and surrounding ligaments at the inner mouth of the cervix, coupled with the support of the fetal prenatal exposure part of the anterior amniotic fluid capsule is wedge-shaped, so that the cervical canal is funnel-shaped, and at this time, the cervix will be shortened and disappear gradually. Therefore, the length of the cervix generally has no effect on labor.
However, the length of the cervical canal is one of the scoring indicators of cervical maturity. A longer cervical opening indicates poor cervical maturity, and medications such as dinoprostenol suppositories may be needed to promote cervical maturity, thus speeding up the progress of labor.
Pregnant women are advised to consult a medical professional and undergo relevant examinations before delivery, and choose the appropriate mode of delivery under the guidance of the doctor, taking into account the results of the examination.
