Eligibility Criteria
Inclusion
- The study database will include all the patients who performed a single cryopreserved blastocyst transfer, between January 2019 and June 2023, including also PGTA and repeated ART cycles.
- The embryologist's experience will be assessed in terms of number of previous cryopreservation (vitrification) and thawing procedures. We will include in the study all the embryologists who performed at least 50 freezing and thawing.
Exclusion
- The blastocysts transferred from other centres and the donor blastocysts will be excluded from the study, as well as multiple blastocysts transfers and the LP cycles, to reduce the risk of selection bias or physician-embryologist couple bias.
- The embryologists who performed less than 50 freezing and thawing will be excluded from the study.
- Similarly, the first 50 procedures performed by each embryologist will not be counted in the data set.
