Tubal reversal success rates vary from patient to patient, based on many difference characteristics. It also varies depending on what we call success.
Success at achieving reanastamosis (reconnection) of at least one fallopian tube exceeds 90%.
Success at achieving pregnancy depends on many factors, including patient age, where on the tube the sterilization was performed, what method was used to sterilize, how much healthy tube remains, and other fertility factors including the male partner.
Measuring all patients who have tubal reanastamosis, 60-70% of women undergoing reversal achieve pregnancy within 1 year of surgery.
