The fallopian tubes play a pivotal role in the entire process of conception and are the conduits for the transportation of sperm and eggs. Once the fallopian tube is diseased, it will lead to infertility. In the research, it is found that traditional fallopian tube blockage, fallopian tube obstruction, fallopian tube pass but not smooth, fallopian tube accumulation, fallopian tube adhesion become the main culprits leading to women’s infertility, and the incidence rate is also increasing year by year. Fertility experts introduced, has suffered from adnexitis, purulent appendicitis, tuberculosis peritonitis, tuberculosis, endometriosis patients, have had an incomplete abortion, abortion fever, abdominal pain and puerperal infection patients, gonorrhea and other sexually transmitted diseases, as well as patients with tubal deformities, may lead to tubal function abnormalities, suffering from tubal infertility. Three kinds of tubal diseases are easy to cause infertility Tubal disease is a common gynecological disease, but also a common cause of infertility, accounting for 1/3 of infertility patients.clinically, tubal disease can cause infertility there are three kinds of cases: First, tubal obstruction Obstruction can be divided into three types: one is the tubal pass but not fluent, caused by the debris in the tube, the detached cells or blood clots obstruction, etc., which accounted for 53.2%; the second is the fallopian tube, the fallopian tube can not be closed, the degree of damage is mild, but the fallopian tube is not smooth. The second is that the fallopian tube is occluded and impassable, the degree of damage is light, and most of the fallopian tube is normal, which accounts for 29.7%; the third is that the fallopian tube is completely impassable, and the damage is serious, which accounts for 17.1%. Secondly, tubal pelvic adhesion Uterus, ovary, fallopian tube, intestinal adhesion, so that the egg can not be combined with sperm, resulting in infertility. Thirdly, tubal fluid accumulation and umbilical atresia After the inflammation of fallopian tube, due to adhesion and atresia, the secretion of mucous membrane cells accumulates in the lumen of the tube, or due to the inflammation of fallopian tube the isthmus and umbilical end of the tubal adhesion occurs, and pus accumulates in the tubal tube after the blockage is formed, and when the pus cells in the lumen of the tubal tube are absorbed, it eventually becomes watery fluid. Methods to prevent tubal infertility Infertility experts pointed out that the fallopian tube is a pair of slender and curved tubes, the inner and uterine horns are connected, the outer end of the free, and the ovary is close to the whole length of 8 ~ 14cm, with the transport of sperm, eggs and fertilized eggs, as well as to provide sperm storage, energy, acrosomal reaction and fertilization site and other physiological functions, is one of the main components of the female reproductive system. So the prevention of tubal infertility need to pay attention to the following points: 1, prevention of vaginal infections Disease occurrence and development have a process, there is a reason for the tubal infectious diseases, mainly should be in the prevention of vaginal (vaginal) inflammation, endometritis, etc. work, especially the vaginal (vaginal) infection, is the key to many reproductive system diseases “portal “It is extremely important to pay attention to the protection of the reproductive system, pay attention to sexual hygiene and prevent sexually transmitted diseases. 2, careful abortion abortion is also the main reason for tubal failure: abortion due to mechanical or drug stimulation, uterine smooth muscle tonic contraction, the contents of the uterine cavity is not only to the direction of the uterine mouth to move, at the same time will also enter the fallopian tube cavity, into the tubal cavity of the tissues is easy to stay mechanized, if the fallopian tube cavity is completely obstructed then the formation of infertility, if the formation of semi-obstructed state, the fallopian tube through and not smooth then easy to form an ectopic pregnancy. If the tubal cavity is completely blocked, infertility will be formed. Therefore, abortion should be done carefully before the end of childbearing. In addition, once found that there is inflammation of the reproductive system and pelvic and abdominal inflammation, we should actively find a specialist to carry out effective treatment. Many of the causes of tubal impassability are due to improper and excessive treatment in the process of infertility diagnosis and treatment. Such as repeated tubal lubrication and purging treatment in some small clinics. 3.Prevention of inflammation The main cause of tubal blockage is inflammation, including blockage of tubal lumen caused by salpingitis and blockage of umbrella end caused by pelvic inflammatory disease. Therefore, paying attention to the cleanliness and hygiene of the reproductive system and preventing the infection of various pathogens (especially sexually transmitted diseases) is the most crucial. In addition, most of the ectopic pregnancy is actually caused by inflammation that makes the fallopian tube partially blocked, after the occurrence of ectopic pregnancy, should avoid open tubectomy, try to use laparoscopic tubal opening, if the situation permits, can also be used in conservative treatment, so that the fallopian tube can be retained. 4, timely diagnosis and treatment as soon as possible Timely diagnosis of a variety of methods. Tubal ventilation test, tubal water test, hysterosalpingography, uterine tube ultrasonography, endoscopy (laparoscopy, hysteroscopy, tuboscopy), radionuclide hysterosalpingography and other tests can be carried out in general specialized hospitals, and if necessary, can also be opened to explore, in short, a clear and timely diagnosis can be made. Early diagnosis is good for controlling the development of the disease.
