Abstract
OBJECTIVE
To investigate whether the euploidy rate of blastocysts derived from smooth endoplasmic reticulum aggregates (SERa) positive cycles and oocytes are impacted.
DESIGN
Retrospective cohort study.
METHODS
A total of 601 preimplantation genetic testing (PGT) cycles with at least one oocyte retrieved in our center between April 2017 and May 2021 were initially included in the study. Women>35 years and PGT cycles with chromosomal structural rearrangements (PGT-SR) were excluded. Embryological and blastocyst ploidy outcomes were compared among SERa+ oocyte, sibling SERa- oocytes and oocytes in SERa- cycles.
RESULTS
No significant difference was observed among the SERa+ oocyte group, sibling SERa- oocyte group, and SERa- cycle group in the normal fertilization rate (82.1% vs. 77.8% vs. 83.1%, respectively, P=0.061), blastocyst formation rate (71.0% vs. 72.5% vs. 68.4%, respectively, P=0.393), good quality blastocyst formation rate (46.4% vs. 48.3% vs. 42.6%, respectively, P=0.198). No significant difference was observed in the euploidy rate (50.0% vs. 62.5% vs. 63.3%, respectively, P=0.324), mosaic rate (12.5% vs. 9.7% vs. 13.4%, respectively, P=0.506), and aneuploidy rate (37.5% vs. 27.8% vs. 23.2%, respectively, P=0.137) among the three groups.
CONCLUSION
Our results suggest that the euploidy rate of blastocysts derived from SERa+ cycles and oocytes may not be impacted.
