Tubal ligation. 1  There is a slight risk of becoming pregnant after tubal ligation. This happens to about 5 out of 1,000 women after 1 year. 2  Pregnancy may occur if: The tubes grow back together or a new passage forms (recanalization) that allows an egg to be fertilized by sperm.
Besides your age, getting pregnant after tubal reversal depends on things such as: 1  Type of tubal ligation procedure you had. 2  Length of your remaining fallopian tubes, and whether they still work properly. 3  Amount of scar tissue in your pelvic area.  Results of your partner's sperm count and other fertility 1  tests. Your surgeon's skill.
