A decision analysis of treatments for obstructive azoospermia.
BACKGROUND
Treatments for post-vasectomy obstructive azoospermia include vasectomy reversal, microsurgical epididymal sperm aspiration (MESA) or percutaneous testicular sperm extraction (TESE) with IVF/ICSI. We examined the cost-effectiveness of these treatments.


METHODS
A decision analytic model was created to simulate treatment. Outcome probabilities were derived from peer-reviewed literature and the Society for Assisted Reproductive Technologies database. Procedural costs were derived from a sampling of high-volume IVF centers and the Medicare Resource Based Relative Value Scale. Indirect costs of complications, lost productivity and multiple gestation pregnancies were considered. Sensitivity analyses were performed.


RESULTS
Vasectomy reversal was more cost-effective than either MESA or TESE under all probability conditions. In 1999, vasectomy reversal demonstrated superior cost-effectiveness to TESE and MESA ($19,633 versus $45,637 and $48,055, respectively, equivalent to $25,321 versus $58,858 and $61,977 in 2005 dollars). In 2005, vasectomy reversal ($20,903) remained the most cost-effective treatment over TESE ($54,797) and MESA ($56,861). The cost-effectiveness of all treatments improved over projections by inflation. The relative cost-effectiveness of the therapies was unchanged over time.


CONCLUSIONS
Vasectomy reversal appears more cost-effective than percutaneous TESE and MESA for treatment of obstructive azoospermia when the impact of indirect costs is considered. The absolute cost-effectiveness of all therapies improved over time. These results may be tailored with institution-specific data to allow more individualized results.
