N88: Other noninflammatory disorders of cervix uteri

N88.2: Stricture and stenosis of cervix uteri

The uterus or womb sits in the pelvis and is pear-shaped. The narrower part extends downward into the vagina and is called the cervix. When a woman is pregnant, the child grows in her uterus.

There is a canal in the cervix that connects the vagina to the inside of the uterus. The orifice at the end of this canal is called the mouth of the womb (ostium uteri). The mouth of the womb is visible during an internal examination of the vagina.

The canal in the cervix can become constricted as a result of disease, medical treatment or during the menopausal transition, for example. Tissue may then start to fuse together, for example.

If the cervix is narrower than usual you may experience severe periods, for example. If the cervix is too narrow, this can also cause periods to become irregular or cease entirely. You may also be unable to conceive.
