Lack of evidence to support the superiority of TLI over conventional morphology to select among euploid embryos determined by PGT-A.

Highlights from the article: But according to another large sample euploid blastocysts performed by Nazem et al. [[3]], there was no difference in the various pregnancy outcomes of blastocysts with a TE grade of A or B (inferred from the literature); then, inner cell mass (ICM) became a better predictor. These time parameters are closely related to the speed of blastocyst formation and ultimately affect the date of blastocyst biopsy.
