The purpose of this study was to evaluate the effect of sequential embryo transfer in patients with repeated IVF failure. A retrospective matched case–control study was conducted and the outcomes of 213 patients with a history of repeated IVF–embryo transfer failure were analysed, of which 33 women underwent sequential embryo transfer on day 2 and day 3 (D2/D3 group), 66 women on day 3 and day 5 (D3/D5 group), 85 women underwent day-3 embryo transfer only (D3 control group) and 29 women underwent day-5 embryo transfer only (D5 control group) in the assisted reproduction centre of the Sixth Affiliated Hospital of Sun Yat-sen University from August 2010 to December 2011. The results showed that the clinical pregnancy rate of the D2/D3 group was higher than that of the D3 group (48.5% versus 22.4%, P = 0.006) while the clinical pregnancy rates of the D3/D5 and D5 groups were not significantly different (50.9% versus 45.8%). Day-2 and day-3 sequential embryo transfer may improve the clinical outcomes for patients with repeated IVF–embryo transfer failures.The purpose of this study was to evaluate the effect of sequential embryo transfer in patients with repeated IVF failure.
