Abstract
Pre-Implantation Genetic Testing for Aneuploidy (PGT-A) has become a powerful tool for improving pregnancy outcomes. When PGT-A results are “undetermined”, offering no insight on the chromosomal makeup of an embryo, many patients are skeptical about seeking rebiopsy of those embryos due to concerns that inconclusive results may be indicative of poor embryo or DNA quality that will prevent a conclusive result even after rebiopsy. Due to limited research on the relationship between undetermined embryos and their rebiopsy results, there is a prevalent exclusion of those embryos as transferable options. This limits the pool of utilizable embryos. 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.
