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 tube is completely impassable and the damage is severe; second, the fallopian tube is occluded and impassable, but the damage is relatively mild; third, the fallopian tube is open but not smooth. Women in daily life if prevent the occurrence and spread of inflammation, reduce fallopian tube disease? 1, pay attention to hygiene Sexual life should pay attention to their own personal hygiene and partner. Before and after sex, both men and women should wash the external genitalia to prevent bacterial growth. If women menstruation and the appearance of vaginal bleeding, must prohibit sex, so as to avoid bacterial growth and reproduction. In addition, female friends should use running water to wash the vulva, keep the vulva dry and clean. 2, enhance physical fitness female friends should pay attention to exercise, enhance physical fitness, especially in the abortion, menstruation or childbirth should pay attention to strengthen the nutrition, eat more nutritious food, and actively participate in physical exercise, improve their own immunity, resistance, reduce the chances of disease attack. 3.Scientific contraception If there is no plan to have children, we should take scientific and reliable contraceptive measures such as taking oral contraceptive pills, the correct use of condoms, to prevent unwanted pregnancies, so as to avoid abortion resulting in uterine adhesions, tubal obstruction. 4, active treatment of gynecological diseases Inflammation or infection of nearby 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 the genital inflammation, must be treated in time to avoid inflammation infection of the fallopian tubes, resulting in tubal blockage. 5, avoid improper uterine surgery Women should pay attention to good disinfection measures during abortion, gynecological diseases and other examinations or treatments, so as not to breed bacteria. Scraping, episiotomy, tubal fluids 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 abortion, patients must choose the regular public hospitals to protect the safety of the operation to avoid leading to fallopian tubal pelvic disease.
