A variant of embryo transfer in which embryos are cultured in vitro for an extended period in sequential or continuous media until reaching the blastocyst stage (day 5 or 6 post-follicular aspiration). This technique allows for a more rigorous embryo selection, improves endometrial synchrony, and maximizes implantation rates, facilitating a single embryo transfer (SET) policy.

Examples

Despite there are no benefits in terms of cumulative pregnancy rate per initiated cycle, there is a trend toward to perform blastocyst transfer rather than cleavage embryo transfer, due to the fact that after fresh blastocyst transfer there are higher rates on live births and clinical pregnancies.

The study period spanned a decade during which significant advancements in ART occurred, including a transition from double cleavage-stage embryos to single blastocyst transfer practices and the widespread adoption of vitrification over slow-freezing methods.
