The main reason for not having intercourse within 1 month after tubectomy is the special anatomical relationship between women, such as the vagina and the cervix, and the cervix and the fallopian tubes, which will be traumatized if the tubes are removed. If the pathogenic bacteria enter the cervical area through the vagina and enter the uterine cavity to reach the traumatic area, it will lead to infection and cause serious consequences. Therefore, you should not have intercourse within 1 month after the tubectomy, but you can have sex if you have resumed menstruation once after the operation and if you have no other symptoms, not forever. When having sex, we should pay attention to the fact that it is impossible to get pregnant if both tubes are removed, but it is possible to get pregnant if one of the tubes is preserved. It is recommended to take good contraceptive measures and pay attention to the hygiene of sexual life if you are not planning to get pregnant.
