Why do fallopian tubes become blocked?

Patient's question:

Got married for 2 years and have never been pregnant, and the body has always felt uncomfortable. During a physical examination, I found that my fallopian tubes were blocked. The doctor said it affects pregnancy. Please ask: Why are the fallopian tubes blocked?

Doctor's answer:

Why does fallopian tube blockage occur? The lumen of the fallopian tube is relatively narrow, with the diameter of the narrower section being only 1–2 mm. When tubal inflammation occurs again, the narrower section of the fallopian tube and the fimbriae are easily re-adhered or completely self-locked. Tubal inflammation often first affects the fallopian tube lining, causing edema of the inner lining, interstitial edema, congestion, and exudation. The shedding of the fallopian tube mucosal epithelium leads to mutual adhesion of the mucosa or adhesion of the fallopian tube fimbriae, resulting in lumen self-locking and infertility.
Why does fallopian tube blockage occur? If you want to conceive quickly, it is recommended to have a thorough examination at an infertility hospital before pregnancy to rule out the possibility of infertility.
