If the fallopian tube is blocked again after a tubal ligation, depending on the degree of blockage and the individual’s wish, he/she may choose to undergo another surgery or adopt a treatment plan such as artificial insemination. 1. Re-operation: Generally applicable to those with lesser degree of blockage, you need to choose the way of re-operation after consultation with your doctor, including laparoscopic surgery and other methods. If the reopening surgery is successful, it is recommended to get pregnant as soon as possible to avoid reoccurrence of adhesion and blockage. 2. Artificial insemination: Artificial insemination generally refers to in vitro fertilization (IVF), i.e., getting pregnant through in vitro fertilization and embryo transfer. It is generally used in cases where the degree of blockage is more serious, or if you no longer want to try tubal ligation surgery for personal reasons, you can achieve pregnancy through artificial fertilization. Therefore, when tubal blockage occurs again after tubal ligation surgery, the appropriate treatment plan can be chosen based on the severity of the blockage and the individual’s wishes.
