Pregnancy and perinatal outcomes after day 5 versus day 6 blastocyst‐stage embryo transfer: A systematic review and meta‐analysis
The findings suggested that transfer D5 blastocysts should be prioritized over D6 blastocysts in SFBT in clinical practice. Besides, poor-quality D5 blastocysts and D6 high-quality blastocysts exhibited comparable outcomes. Given the overall low quality of available evidence, the association between the pregnancy outcomes and blastocyst development speed requires further investigation.
