To compare the economic consequences of proceeding directly to IVF to those of proceeding with gonadotropins followed by IVF in patients < 35 years of age with unexplained infertility. Design: A decision-tree- model. The model incorporated the cost and success of each infertility regimen as well as the pregnancy-associated costs of singleton or multiple gestations and the risk and cost of cerebral palsy. Main Outcome Measure(s): Cost per live birth. Result(s): Both treatment arms resulted in a >80% chance of birth. The gonadotropin arm was over four times more likely to result in a high-order multiple pregnancy (HOMP). Despite this, when the base case estimates were utilized, immediate IVF emerged as more costly per live birth. In sensitivity analysis, immediate IVF became less costly per live birth when IVF was more likely to achieve birth (55.1% ) or cheaper (＄ 11,432) than our base case assumptions. Conclusion(s): After considering the risk and cost of HOMP, immediate IVF is more costly per live birth than a trial of gonadotropins prior to IVF.
