What are the clinical manifestations of cervical infertility?

Patient's question:

I've always had pain down there in the room, and it's been this long without getting pregnant. After a check-up, it was said to be cervical inflammation.

Doctor's answer:

1. Cervical canal dysplasia can be accompanied by uterine dysplasia. Severe dysplasia of the cervix appears slender. In moderate dysplasia, the ratio of cervical length to uterine body is 1:1, known as the "adolescent-type uterus." Cervical dysplasia can lead to insufficient secretion function of cervical glands.
2. Cervical canal atresia and stenosis Congenital cervical atresia or stenosis is mostly caused by incomplete formation and fusion of the lower segments of both Müllerian ducts. Clinically rare, it is often accompanied by uterine hypoplasia, and secondary sexual characteristics are mostly normal. If the patient's endometrium is functionally good, cyclic lower abdominal pain may occur during puberty due to endometrial hematoma, or menstrual hypomenorrhea with dysmenorrhea may occur. Menstrual blood can also flow retrograde through the fallopian tubes into the abdominal cavity, causing pelvic endometriosis. Acquired cervical canal atresia and stenosis are more common after artificial abortion or after cervical electrocautery or cryotherapy. The main reasons are insufficient cervical dilation during aspiration, or the removal of the aspirator with negative pressure, resulting in cervical endometrial injury and wound adhesion and atresia. Cervical inflammation treatment with excessive electrocautery or cryotherapy can lead to cervical canal adhesion or stenosis. Clinically, it manifests as amenorrhea with cyclic lower abdominal pain after artificial abortion or cervical inflammation treatment. Gynecological examination reveals a purplish-blue vagina, significant cervical elevation tenderness, slightly full and mobile uterine body with tenderness.
