Journal Club Global - Recurrent Implantation Failures in ART: Myth or Reality?

Classically, implantation failures in ART were believed to result from alterations in embryo or endometrium quality. The advent of PGT-A has allowed for the transfer of only genetically normal embryos. However, not all euploid embryos implant, which leads us to question the role played by the endometrium. Several tests have been designed to assess receptivity, but none are fully validated.

In light of this, Pirtea, et al. from Richard Scott’s team in Basking Ridge, New Jersey designed a large retrospective study to assess whether women who previously failed a euploid embryo transfer were at greater risk of implantation failure on the occasion of the second and third frozen euploid blastocyst transfers. Results from 4,429; 784; and 131 successive frozen euploid embryo transfers showed practically no reduction in sustained implantation chances with successive transfers.

Ultimately, the cumulative sustained implantation and live birth rates after three successive frozen euploid blastocysts transfers (the definition of recurrent implantation failure) were 95.2% and 93.7%, respectively. These results therefore indicate that the role played by the endometrium in implantation failures is probably minimal.
