For women whose fallopian tubes are open after tubal ligation, if there is still inflammation in the fallopian tubes, then it will lead to its blockage again, and at the same time, due to individual differences cannot determine the time of its reoccurrence of blockage; if there is no inflammation in the local area, then it will not be blocked again in general. As women have a higher chance of getting pregnant in the six months after the tubal ligation, so women should actively prepare for pregnancy after the operation. Sexual life and pelvic bath should be prohibited in 2 weeks after the ligation operation, and antibiotics such as cephalosporin and penicillin should be given to prevent infection if necessary. For women who have normal sex life but have not been pregnant, it is necessary to improve the tubal imaging or tubal fluids to ensure the smoothness of the fallopian tubes.
