Objective To compare cost and efficacy of tubal anastomosis to in vitro fertilization (IVF) in women who desired fertility after a tubal ligation. Design Cost-effectiveness analysis. Setting Not applicable. Patient(s) Not applicable. Intervention(s) Not applicable. Main Outcome Measure(s) Cost per ongoing pregnancy. Result(s) Cost per ongoing pregnancy for women after tubal anastomosis ranged from $16,446 to $223,482 (2014 USD), whereas IVF ranged from $32,902 to $111,679 (2014 USD). Across maternal age groups <35 and 35–40, years tubal anastomosis was more cost effective than IVF for ongoing pregnancy. Sensitivity analyses validated these findings across a wide range of ongoing pregnancy probabilities as well as costs per procedure. Conclusion(s) Tubal anastomosis was the most cost-effective approach for most women less than 41 years of age, whereas IVF was the most cost-effective approach for women aged ≥41 years who desired fertility after tubal ligation. A model was created that can be modified based on cost and success rates in individual clinics for improved patient counseling.
