How is it generally understood and how can it be prevented if a woman has had three ectopic pregnancies?

Patient's question:

Treatment and outcomes in the past year: Didn't care what kind of help: Is there a problem with sperm?

Doctor's answer:

Generally, the causes of ectopic pregnancy include:
1. Women with chronic tubal inflammation.
2. Individuals with poorly developed or malformed fallopian tubes, such as inadequate muscle layer development or a lack of cilia in the lining.
3. Women with endometriosis. This is because the endometrium that has grown outside the fallopian tubes (specifically in the interstitial part) can thicken, leading to narrowed or blocked tubal lumen.
4. The presence of tumors in the pelvic cavity. The pushing and pulling of these tumors can cause rapid and abnormal movement or changes in the position and shape of the uterus or fallopian tubes, potentially even leading to structural abnormalities.
