Reproductive Outcomes of Transferring Blastocysts Derived From Frozen-Thawed Cleavage Embryos: A Systematic Review and Meta-Analysis.

ABSTRACT:

Background

In in vitro fertilization (IVF), transferring frozen-thawed blastocysts is a widely adopted practice. This meta-analysis aims to evaluate the reproductive outcomes of transferring blastocysts derived from frozen-thawed cleavage embryos (FT-CDB group) compared to direct frozen-thawed blastocyst (DFB group) transfers.

Methods

We searched the following electronic databases for relevant studies: PubMed/MEDLINE, EMBASE, Scopus, and Web of Science. Studies were included if they compared the clinical and neonatal outcomes of IVF patients receiving either FT-CDB or DFB transfer with vitrification method. The protocol for this review has been registered in PROSPERO.

Results

A total of seven studies (2057 patients) were included in the analysis. Participants in the F
