What is the cause of the crooked cervix?

If you find that your cervix is ​​crooked during the examination, it is still quite serious, and this situation usually cannot be effectively treated with medication. Most patients must go to the hospital for a detailed examination and then undergo surgery as soon as possible. This can prevent themselves from affecting future fertility and making fertility more difficult.

1. Cervical atresia and stenosis Congenital cervical atresia or stenosis is mostly caused by incomplete formation and fusion of the lower segments of the bilateral Müllerian ducts. It is rare clinically and is often accompanied by uterine hypoplasia, while secondary sexual characteristics mostly develop normally. If the patient's endometrium functions well, she may experience periodic lower abdominal pain or scanty menstruation with dysmenorrhea during adolescence due to blood accumulation in the uterine cavity. Menstrual blood may also flow back into the abdominal cavity through the fallopian tubes, causing pelvic endometriosis.

Acquired cervical atresia and stenosis are often seen after induced abortion or after electrocautery or cryotherapy for cervicitis. The main reason is that the cervix is ​​not fully dilated during suction, or the suction tube is removed with negative pressure, causing damage to the cervical endometrium and adhesion and closure of the wound. Electrocautery or cryotherapy for cervicitis may be too deep, leading to adhesion or stenosis of the cervical canal. The clinical manifestations are amenorrhea accompanied by cyclical lower abdominal pain after artificial abortion or treatment of cervicitis. Gynecological examination revealed that the vagina was purple-blue, the cervix was obviously painful when lifted, and the uterus was slightly full and mobile with tenderness.

2. Cervical hypoplasia may be accompanied by uterine hypoplasia. A severely dysplastic cervix is ​​elongated. The ratio of cervical length to uterine body in moderately hypoplastic cases is 1:1, which is the so-called "adolescent uterus". Cervical dysplasia can lead to insufficient secretory function of cervical glands.

3. Abnormal position of the cervical canal is often accompanied by abnormal position of the uterine body. 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.
