Cervical stenosis is a narrowing of the canal of the cervix. The cervix is the lower part of the uterus (womb). It connects the uterus with the vagina.


This problem can happen when the canal becomes inflamed. Common causes of this are:

Some people have this problem at birth. It is not known why this happens.

Risk Factors

This problem is more common after menopause.

The risk of this problem is also higher in people:

  • Whose mothers took diethylstilbestrol during pregnancy
  • Have endometriosis


Most people do not have problems. Those who do may have:

  • Painful periods
  • Absent periods
  • Abnormal bleeding
  • Problems getting pregnant


The doctor will ask about symptoms and past health. Physical and pelvic exams will be done. The doctor may have problems passing tools through the cervix during the pelvic exam. This is often enough to make the diagnosis.


People who are not having problems do not need treatment.

If needed, a procedure will be done to widen the canal. Rods will be passed into the canal to stretch the cervix. A mesh tube may also be put into the cervix for a few weeks. It will help to prop open the cervix until the area heals. Tissue may be removed from the cervix.


There are no known steps to prevent stenosis of the cervix.
