What causes cervical insufficiency?

Women's cervix may have many abnormal problems, such as cervical erosion, cervicitis and other diseases. These diseases are often heard of and are relatively familiar to everyone. In contrast, many people do not know what cervical insufficiency is. In fact, cervical insufficiency is also called incomplete closure of the internal cervical os. This is an abnormal condition of women's cervix. So what is the cause of this result?

What are the causes of cervical insufficiency?

Cervical insufficiency is also one of the very common causes that can lead to cervical infertility, and therefore can cause great pain to female patients. So what are the common causes of this disease? Let's take a look.

1. Congenital cervical insufficiency

Research has found that one-third of patients with this disease have some congenital factors, the most common of which are unicornuate uterus or septate uterus.

2. Acquired cervical insufficiency

This is also a cause of cervical infertility. Generally, it is because after a woman undergoes gynecological surgery, the normal structure of the cervix or the lower part of the cervix is ​​damaged to a certain extent, leading to this situation.

3. Physiological cervical insufficiency

In addition, physiological cervical incompetence can also cause this disease. This situation is generally seen in patients with uterine contraction or hypotonic internal cervical os, which is a normal physiological phenomenon.

Cervical fibroids

The main cause of infertility caused by cervical fibroids is deformation and narrowing of the cervical canal, which affects the passage of sperm. The main clinical manifestations are irregular menstruation, increased menstrual blood volume, increased leucorrhea or bladder and rectal symptoms. Some patients have no symptoms. Gynecological examination may reveal protruding myoma nodules in the cervix or changes in the shape of the cervix. The cervix on the side where the myoma is located is enlarged, while the opposite side is compressed and thinned, and the external os of the cervix is ​​stretched and flattened into a twist shape.

Abnormal position

Chronic pelvic inflammatory disease or endometriosis can cause the uterus to be extremely retroverted, retroflexed or anteflexed, causing the external cervical os to stick to the anterior fornix, causing the posterior fornix to become shallow and lose its function as a sperm storage pool, which is not conducive to the upward movement of sperm. In addition, cervical elongation, shortening or cervical prolapse may also change the normal positional relationship between the external cervical os and the posterior fornix, hindering the upward movement of sperm.
