Summary

Story summary

A study on cryopreserved blastocyst transfer (CSBT) found non-re-expanded blastocysts can still result in pregnancies, though with lower success rates.
Maternal age and embryo quality had minimal impact on outcomes.
The study advises against discarding blastocysts based solely on re-expansion status, promoting informed patient choices.
Further research is needed to understand mechanisms influencing pregnancy outcomes in CSBT.
