The fallopian tube is an important organ for transporting sperm, collecting eggs and carrying fertilized eggs to the uterine cavity. If blockage of the fallopian tube occurs, the passage of sperm and fertilized eggs will be blocked, resulting in infertility or ectopic pregnancy. Most of the blocked fallopian tubes are asymptomatic and only show difficulties in getting pregnant. A few cases of blocked fallopian tubes due to diseases can have symptoms such as abdominal pain, back pain, increased discharge, painful intercourse, etc. There is no simple self-testing method for tubal blockage, and most of them need the doctor’s expertise and relevant auxiliary tests to determine it. If you are not pregnant after six months of marriage without contraception and with normal frequency of sexual intercourse, you should consider the presence of tubal blockage, and then you should go to the hospital for tubal lavage or tubal imaging or tuboscopy to determine the presence of tubal blockage. If the tubal blockage is proximal, it can be treated by hysteroscopic COOK catheterization or partial tubal resection and anastomosis, if it is interrupted, it can be treated by laparoscopic resection of the blocked part of the fallopian tube and anastomosis of the two broken ends of the tube. If the blockage is distal, it can be treated by tubal resection, ostomy and tubal paraplasty.
