The best time for tubal reversal is usually 3~7 days after menstruation, and it is also recommended to perform it one or two months before pregnancy. 1. For uterine or abdominal operation, it is usually performed 3-7 days after menstruation when the uterine lining is relatively thin, which reduces the chance of bleeding and the chance of infection. 2. The best time to get pregnant after tubal ligation surgery is six months after the surgery. The longer the time after the surgery, the greater the chance of recurrence of tubal blockage, so this surgery is not advocated too early in the preparation for pregnancy, otherwise the fallopian tubes blocked again, the significance of the surgery will diminish, and the chances of a successful pregnancy diminish.
