REBIOPSY OF EMBRYOS WITH UNDETERMINED PGT-A RESULTS DOES NOT LEAD TO A . . . In this study, we aim to determine whether conclusive results can still be provided via rebiopsy of those “undetermined” embryos, by assessing whether the rate of undetermined results is consistent among first-time biopsied and rebiopsied embryos A multi-center study was performed
Blinded rebiopsy and analysis of noneuploid embryos with 2 distinct . . . Four rebiopsies were collected from each embryo: 3 TE biopsies and the remaining embryo Each rebiopsy was randomized, blinded, and assessed with an SNP array-based PGT-A platform that combines copy number and allele ratio analyses, without mosaicism reporting
Study examines PGT-A outcomes of inconclusive rebiopsied . . . - Remembryo Researchers in a 2023 study found reduced live birth rates with inconclusive embryos that were rebiopsied, and increased miscarriage rates They also examined the factors that are associated with inconclusive results, and found that the method of biopsy was the most significant
Effect of re-biopsy and re-vitrification on clinical outcomes in . . . To investigate whether re-biopsy and re-vitrification affect embryo developmental potential and clinical outcomes Embryos that underwent preimplantation genetic testing for aneuploidy (PGT-A) and single embryo transfer between December 2017 and April 2024 were studied
Impact of double versus single blastocyst biopsy and vitrification on . . . Current studies reveal a disparity between the reproductive potential of retested blastocysts and the supporting evidence This systematic review and meta-analysis compared clinical outcomes of rebiopsied and revitrified blastocysts with those biopsied and vitrified once
RETESTING EMBRYOS INITIALLY REPORTED AS CHAOTIC BY PREIMPLANTATION . . . This single center retrospective review examined embryos that underwent thaw, rebiopsy, and retesting of an embryo with an initial chaotic PGT-A report PGT-A testing was performed at a single commercial lab using next generation sequencing (NGS) platform
