Double vitrification and warming does not compromise the chance of live birth after single unbiopsied blastocyst transfer.

ABSTRACT:

Study question

Does double vitrification and thawing of an embryo compromise the chance of live birth after a single blastocyst transfer?

Summary answer

The live birth rate (LBR) obtained after double vitrification was comparable to that obtained after single vitrification.

What is known already

Double vitrification-warming (DVW) is commonly practiced to accommodate surplus viable embryos suitable for transfer, to allow retesting of inconclusively diagnosed blastocysts in preimplantation genetic testing (PGT), and to circumvent limitations associated with national policies on embryo culture in certain countries. Despite its popularity, the evidence concerning the impact of DVW practice on ART outcomes is limited and lacking credibility. This is the first thorough inve
