The fallopian tubes are located in the female pelvis, in the uterus left and right fallopian tube each, for a pair of slender and curved tubes, located in the upper edge of the broad ligament 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 composed of. The smoothness of the fallopian tube is one of the main conditions indispensable for conception. the lumen of the fallopian tube is relatively narrow, and the diameter of the narrowest part of the lumen is only 1-2mm. when tubalitis or pelvic inflammatory disease occurs, the narrowest part of the fallopian tube and the umbilical end of the tube will easily develop 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 tube is completely impassable and severely damaged; second, the fallopian tube is occluded and impassable, but the degree of damage is relatively mild; third, the fallopian tube is passable but not smooth. Women in daily life if prevent the occurrence and spread of inflammation, reduce fallopian tube disease? Pay attention to hygiene: pay attention to your own and your partner’s personal hygiene during sex. Before and after sex, both men and women should wash their 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 the regular public hospitals in order to protect the safety of the operation to avoid leading to fallopian tubal pelvic disease.
