Comparing sequential vs day 3 vs day 5 embryo transfers in cases with recurrent implantation failure: randomized controlled trial
OBJECTIVE: The recent improvement in sequential media has refocused its attention on the role of human blastocysts in ART, not only because of its advantages but also because of the possible cancellation of embryo transfer when relying on blastocyst transfer only. Hence, the idea of sequential trans...

description | OBJECTIVE: The recent improvement in sequential media has refocused its attention on the role of human blastocysts in ART, not only because of its advantages but also because of the possible cancellation of embryo transfer when relying on blastocyst transfer only. Hence, the idea of sequential transfer on day 3 and day 5 was proposed. Objective: To compare the pregnancy outcomes of sequential embryo transfer on day 3 and day 5, versus cleavage transfer on day 3 and blastocyst transfer on day 5 in cases of recurrent implantation failure. METHODS: This was a prospective and randomized trial, in which 210 qualified patients with recurrent implantation failures undergoing IVF/ICSI were randomized into three groups, each group included 70 patients. Embryo transfer was performed in day 3 in the first group, day 5 (blastocyst transfer) in the second group and sequential embryo transfer in days 3 and 5 in the third group. We assessed pregnancy outcomes from all the three groups. RESULTS: Clinical pregnancy and live birth rates were significantly higher in the sequential group than either group day-3 or day-5 of embryo transfer in cases with recurrent implantation failures. CONCLUSIONS: Sequential embryo transfer in cases with recurrent implantation failures and adequate number of retrieved oocytes is associated with higher implantation and clinical pregnancy rates, and it is advocated for patients having an adequate number of good quality embryos. |
