What is the cause of tubal adhesion

Patient's question:

Why do fallopian tubes become adhesive? Are there any methods to prevent it? Help: Tell me the reasons and how to solve it

Doctor's answer:

Experts from infertility hospitals explain: The main causes of tubal adhesion are:
1) Postpartum or miscarriage infection: Patients are physically weak after childbirth or miscarriage, and the cervix has been expanded but has not yet fully sealed. At this time, bacteria present in the vagina and cervix may descend and infect the pelvic cavity. If there are residual placenta or fetal membranes in the uterine cavity, the risk of infection is even higher.
2) Infection after gynecological surgery: During procedures such as induced abortion, intrauterine device insertion or removal, tubal irrigation, tubal, polypectomy of the endometrium, or submucosal uterine fibroid removal, if sterilization is not strict or if there is existing chronic inflammation of the reproductive system, postoperative infection may occur.
