A randomized clinical trial to evaluate optimal treatment for unexplained infertility: the fast track and standard treatment (FASTT) trial
Objective
To determine the value of gonadotropin/intrauterine insemination (FSH/IUI) therapy for infertile women aged 21–39 years.
Design
Randomized controlled trial.
Setting
Academic medical center associated with a private infertility center.
Patient(s)
Couples with unexplained infertility.
Intervention(s)
Couples were randomized to receive either conventional treatment (n = 247) with three cycles of clomiphene citrate (CC)/IUI, three cycles of FSH/IUI, and up to six cycles of IVF or an accelerated treatment (n = 256) that omitted the three cycles of FSH/IUI.
Main Outcome Measure(s)
The time it took to establish a pregnancy that led to a live birth and cost-effectiveness, defined as the ratio of the sum of all health insurance charges between randomization and delivery divided by the number of couples delivering at least one live-born baby.
Result(s)
An increased rate of pregnancy was observed in the accelerated arm (hazard ratio [HR], 1.25; 95% confidence interval [CI], 1.00–1.56) compared with the conventional arm. Median time to pregnancy was 8 and 11 months in the accelerated and conventional arms, respectively. Per cycle pregnancy rates for CC/IUI, FSH/IUI, and IVF were 7.6%, 9.8%, and 30.7%, respectively. Average charges per delivery were $9,800 lower (95% CI, $25,100 lower to $3,900 higher) in the accelerated arm compared to conventional treatment. The observed incremental difference was a savings of $2,624 per couple for accelerated treatment and 0.06 more deliveries.
Conclusion(s)
A randomized clinical trial demonstrated that FSH/IUI treatment was of no added value.
