What is Cervical Stenosis?
The cervix is the small organ located at the bottom of the uterus, which opens into the vaginal canal. Cervical stenosis is a condition in which the endocervical cannal narrows or completely closes off, hindering or blocking the passage between the uterine cavity and the vaginal canal.
Not only does a narrow or closed-off cervix complicate pregnancy and conceiving, it can also cause problems with menstruation that can lead to more serious infections or complications.
What causes stenosis of the uterine cervix?
Cervical stenosis can be congenital (present at birth) or it can develop from other conditions or procedures, such as:
- Uterine, endometrial, or cervical cancer
- Cervical dysplasia
- Radiation therapy for cervical or endometrial cancers
- Surgical procedures on the cervix, such as surgery to treat dysplasia
- Surgeries that affect the uterine lining, such as an endometrial ablation
- Cervical/vaginal atrophy
- Postmenopausal vaginal dryness
What are the potential complications of cervical stenosis?
Retrograde menstruation — when menstrual blood flows up through the fallopian tubes into the pelvic cavity — is pretty common and doesn’t often cause problems. However, severe cervical stenosis can prevent regular menstruation, meaning all your menstrual blood has to flow back into the abdomen. Retrograde menstruation can cause extremely painful periods and increase your risk of endometriosis.
Cervical stenosis also increases the risk of cervical laceration and uterine perforation during certain medical procedures. The rigidity and narrowing of the cervix make it more susceptible to injury when instruments are introduced or when the cervix needs to be dilated.
Cervical stenosis can also cause more complications, such as:
Hematometra
A hematometra forms when blood is unable to flow through the cervix properly and accumulates in the uterus. The buildup of blood can lead to inflammation and other complications.
Pyometra
With cervical stenosis, pus can accumulate in the uterus. This condition usually affects women who have cervical stenosis as a result of endometrial or cervical cancer.
What are the symptoms of cervical stenosis?
For some women, especially women who have reached menopause, cervical stenosis may have few or no symptoms.
Some patients may not discover they have cervical stenosis until they start trying to conceive. A narrow or completely closed-off cervical canal can prevent sperm from reaching and fertilizing an egg. The condition can also complicate or prevent fertility treatments such as in vitro fertilization (IVF) and intrauterine insemination (IUI) as the necessary instruments are unable to pass through the closed-off cervix.
Noticeable symptoms of cervical stenosis may include:
- Irregular periods and abnormal bleeding
- No periods (amenorrhea)
- Pain during your period (dysmenorrhea)
- Chronic pelvic pain or bulging in the pelvic area
How is stenotic cervix diagnosed?
Our OB/GYN may suspect cervical stenosis if you’re experiencing some of the above symptoms, especially after cervical or uterine surgery. Sometimes, stenosis is suspected when our doctor has difficulty collecting a sample for a routine Pap or HPV test or difficulty performing an endometrial biopsy.
Hysteroscopy can be used in diagnosing cervical stenosis by allowing direct visualization of the cervical canal and the internal structures of the uterus. During the minimally invasive procedure, a hysteroscope — a thin, lighted telescope-like device — is inserted through the vagina and cervix into the uterus. This tool enables the doctor to examine the cervix and uterus closely for any signs of narrowing or obstruction in the cervical canal.
If you are diagnosed with cervical stenosis, Dr. Aliabadi may want to conduct tests to rule out cervical and endometrial cancers. In order to take a biopsy of your uterine lining, Dr. Aliabadi will need to open the cervix with medication or a procedure called dilation and curettage (also known as a D&C).
The cervical tissue sample is then sent off to our lab to check for cellular abnormalities that could indicate cancer.
What’s the treatment for stenotic cervix?
Our gynecologist can treat cervical stenosis by physically widening the cervix with instruments called dilators. Dilators are thin, lubricated rods that come in progressively larger sizes, which can be inserted one by one until the appropriate cervical dilation has been reached.
In some cases, the doctor will then insert a cervical stent, which is a tube that can keep the cervix from re-closing. The stent may remain in the cervix for four to six weeks.
Some cases can be effectively managed with a combination of dilation and estrogen therapy. A common treatment involves using a copper intrauterine device (IUD) alongside oral contraceptives.
In some cases, surgical intervention may be recommended. Excision of cervical tissue can surgically open the cervical canal by removing tissue. This is not recommended for patients who wish to become pregnant, as the cervix is essential for keeping your growing baby in the uterus.

Cervical stenosis FAQs
How do cervical stenosis symptoms differ between postmenopausal and premenopausal women?
In premenopausal women, cervical stenosis may present with symptoms like abnormal menstrual bleeding, increased menstrual pain, or infertility due to the obstruction of the cervical canal. For postmenopausal women, symptoms can include unusual discharge if fluid becomes trapped behind the blockage.
