Tubal thickening may lead to normal pregnancy or infertility, depending on the severity of the tubal thickening and the presence of bilateral tubal thickening. Thickening of the fallopian tubes refers to morphological changes in the fallopian tubes, and is most commonly seen in diseases such as hydrosalpinx, pus accumulation, masses, pelvic tuberculosis, and acute tubal inflammation, all of which cause certain irritating injuries to the mucosa of the fallopian tubes, making the tubes appear to be adherent and blocked. If one side of the fallopian tube is thickened and the other side of the fallopian tube is functionally and morphologically normal, there is usually a possibility of pregnancy. If the thickening of the fallopian tube is more serious or the bilateral thickening of the fallopian tube may affect the normal fertilization or the fertilized egg can not enter the uterus smoothly, which will reduce the chances of pregnancy, and may even cause ectopic pregnancy. Therefore, when the thickening of fallopian tubes is detected during gynecological examination, women can confirm the diagnosis through relevant examinations such as tubal flushes and tubal angiograms on the advice of the doctor, and take active and effective treatments.
