The fallopian tubes are located in the female pelvis, in the uterus left, right fallopian tube each, for a pair of slender and curved tubes, located in the uterus broad ligament of the upper edge of the uterus, the inner and uterine horns connected to the outer end of the free, and the ovary close to the whole length of 8-15 cm. fallopian tubes are similar to other cavity organs, the wall of the tubes from the inside to the outside of the mucous layer, the muscle layer and the plasma membrane layer is made up of. The smoothness of the fallopian tube is one of the main conditions essential for conception, the lumen of the tube is relatively narrow, the narrowest part of the lumen diameter is only 1 ~ 2mm. when tubalitis, or pelvic inflammatory disease, the narrowest part of the tube and the umbrella end is easy to occur adhesion or complete atresia. As a result, sperms and eggs cannot meet in the tubal lumen, thus causing infertility. There are generally 3 types of tubal infertility: first, the fallopian tubes are completely blocked and severely damaged; second, the fallopian tubes are occluded and blocked but the degree of damage is relatively mild; third, the fallopian tubes are open but not smooth. How can women prevent the occurrence and spread of inflammation and reduce tubal diseases in their daily life? Pay attention to hygiene: pay attention to your own personal hygiene and that of your partner during sex. Before and after sex, both men and women should wash the external genitalia to prevent bacterial growth. If a woman is menstruating and has vaginal bleeding, she must prohibit sex to avoid bacterial growth and reproduction. In addition, female friends should use running water to wash the vulva, keep the vulva dry and clean. Enhance physical fitness: Women should pay attention to exercise and enhance physical fitness, especially after abortion, during menstruation or after delivery, they should pay attention to strengthen nutrition, eat more nutritious food, and actively participate in physical exercise to improve their immunity and resistance, and reduce the chances of disease attack. Scientific contraception: If you have no plan to have children, you should take scientific and reliable contraceptive measures such as taking oral contraceptive pills and using condoms correctly to prevent unwanted pregnancies, so as to avoid abortions that may lead to uterine adhesions and tubal obstruction. Active treatment of gynecological diseases: Inflammation or infection of adjacent organs can also lead to tubal blockage, such as: appendicitis spread to the fallopian tubes leading to tubal adhesions, pelvic adhesions. Vaginitis, cervicitis, endometritis and other upstream infections can cause inflammation of the fallopian tubes, therefore, once genital inflammation occurs, it must be treated in time to avoid inflammation infection of the fallopian tubes, resulting in tubal blockage. Avoid improper uterine surgery: women should pay attention to good disinfection measures when they have abortion, gynecological diseases, etc. for examination or treatment, so as not to breed bacteria. Scraping, episiotomy, tubal lubrication and other uterine surgery is not only easy to damage the reproductive organs, but also infected with bacteria, so women should try to avoid or reduce the number of uterine surgery, if you have to carry out abortion, the patient must choose a formal public hospital to protect the safety of the operation to avoid leading to tubopelvic disease.
