Question: how many years does it take for your tubes to come untied?
Answer: This happens to about 5 out of 1,000 women after 1 year. After a total of 5 years following tubal ligation, about 13 out of 1,000 women will have become pregnant. Pregnancy may occur if: The tubes grow back together or a new passage forms (recanalization) that allows an egg to be fertilized by sperm.
