The fallopian tubes are a pair of slender and curved tubes located on both sides of the uterus. The inner end of the tube communicates with the uterus and is the opening of the fallopian tube of the uterus; the outer end is free and often attached to the surface of the ovary; the total length is 8 to 14 cm.
The main function of the fallopian tube is to capture the egg released from the ovary and provide a place for the sperm and egg to meet.
Sperm and egg usually combine in the ampulla segment of the fallopian tube to become a fertilized egg. The peristalsis of the fallopian tube helps the fertilized egg travel to the uterine cavity. If the fallopian tube becomes pathological, it will affect the above functions to varying degrees. For example, inflammation of the fallopian tubes can lead to destruction of the mucosal layer of the lumen, the formation of scars, adhesions, and even blockage of the lumen. Mycobacterium tuberculosis is the main pathogenic bacteria that can cause salpingitis. It is also common for other pathogenic bacteria to cause fallopian tube inflammation. Failure to pay attention to menstrual hygiene and improper sexual life can cause pathogenic bacteria to spread through the vagina and uterus to the fallopian tube and pelvic cavity, causing adnexitis or pelvic inflammatory disease. If not treated promptly, it can lead to fallopian tube obstruction. Some women resume sexual life prematurely before their uterus returns to normal after abortion or childbirth, causing inflammation and obstruction of the fallopian tubes, and even secondary infertility, which they later regret.
Endometriosis can also affect the fallopian tube, or cause obstruction of the lumen, or adhesion between the fallopian tube and surrounding organs, seriously affecting the normal peristalsis of the fallopian tube or changing the normal anatomical position of the fallopian tube, making it Unable to capture eggs released by the ovaries. All these pathological changes have become important causes of infertility. Artificial fallopian tube ligation is to artificially block the fallopian tube lumen to achieve sterilization.
