Cervical adhesions are a condition in which the mucous membrane of the cervical canal is damaged or inflamed, resulting in narrowing or complete occlusion of the cervical canal. Typical symptoms usually appear about one month after the cervical injury. The symptoms vary depending on the degree of cervical adhesions. Patients with complete cervical adhesions may experience secondary amenorrhea, in which the menstrual blood cannot flow out at all and is retained in the uterine cavity, resulting in periodic severe lower abdominal distension, fluid and blood accumulation in the uterine cavity, and if secondary infection occurs, pus accumulation in the uterine cavity, which may also be accompanied by systemic symptoms such as elevated body temperature and elevated blood count. The menstrual cycle and duration of menstruation are the same as before. If the adhesions of the cervix prevent the sperm from entering the uterus through the cervix, fertilization cannot be achieved, thus causing infertility. When the doctor applies the probe, resistance can be felt at the cervix, and if it can be probed, dark red and sticky menstrual blood can subsequently flow out, and if there is pus accumulation, it can be seen after probing. The clinical symptoms caused by cervical adhesions vary depending on the degree of adhesion.
