Single blastocyst stage versus single cleavage stage embryo transfer following fresh transfer: A systematic review and meta-analysis

CONCLUSIONS: Our results indicate that single blastocyst stage transfer is associated with higher ongoing pregnancy rate and delivery rate comparing to single cleavage stage transfer in the clinical practice. Due to the low quality of the evidence of the primary outcomes, other higher-quality lager RCTs are necessary before a fully informed decision is made.PMID:34689021 | DOI:10.1016/j.ejogrb.2021.10.004
