Abstract

Research question: What is the cost-effectiveness of gonadotrophins compared with clomiphene citrate in couples with unexplained subfertility undergoing intrauterine insemination (IUI) with ovarian stimulation under strict cancellation criteria? Design: A cost-effectiveness analysis alongside a randomized controlled trial (RCT). Between July 2013 and March 2016, 738 couples were randomized to gonadotrophins (369) or clomiphene citrate (369) in a multicentre RCT in the Netherlands. The direct medical costs of both strategies were compared. Direct medical costs included costs of medication, cycle monitoring, insemination and, if applicable, pregnancy monitoring. Non-parametric bootstrap resampling was used to investigate the effect of uncertainty in estimates. The cost-effectiveness analysis was performed according to intention-to-treat. The incremental cost-effectiveness ratio (ICER) between gonadotrophins and clomiphene citrate for ongoing pregnancy and live birth was assessed. Results: The mean costs per couple were €1534 for gonadotrophins and €1067 for clomiphene citrate (mean difference of €468; 95% confidence interval [CI] €464–472). As ongoing pregnancy rates were 31% in women allocated to gonadotrophins and 26% in women allocated to clomiphene citrate (relative risk 1.16, 95% CI 0.93–1.47), the ICER was €21,804 (95% CI €11,628–31,980) per additional ongoing pregnancy with gonadotrophins and €17,044 (95% CI €8998–25,090) per additional live birth with gonadotrophins. Conclusions: Gonadotrophins are more expensive compared with clomiphene citrate in couples with unexplained subfertility undergoing IUI with adherence to strict cancellation criteria, without being significantly more effective.
