Purpose:
To examine whether double transfer of embryos on day 2-3 and on day 5 after ovum pick-up (OPU) improves IVF/ET success rates in patients with multiple consecutive IVF failures
Methods:
Consecutive IVF failures patients (7.6 +/- 0.5) undergoing IVF/ET cycles were treated with interval double transfer on day 2-3 and on day 5 after OPU. Matched patients, that had embryos transferred only once on day 2 or 3 served as controls.
Results:
Baseline and cycle characteristics were similar in the study group and controls. The total pregnancy rate was 44.6% in the study group and 24.2% in the controls (p = 0.001), and the clinical pregnancy rates were 38.5% and 19.6%, respectively (p = 0.001).
Conclusions:
Patients with multiple consecutive IVF/ET failures, treated with the interval double transfer approach had significantly improved cycle success rates compared with regular day 2 or 3 embryo transfer protocol.
