BACKGROUND Trophectoderm (TE) biopsy and next generation sequencing (NGS) are
currently the preferred techniques for preimplantation genetic testing for aneuploidies (PGT …

BACKGROUND Embryos that are able to form blastocysts have succeeded in activating their
genome and differentiating into two cell types—an external layer of trophectoderm cells …

Preimplantation genetic testing for aneuploidy (PGT-A) remains one of the most
controversial topics in reproductive medicine. With more than 40% of in vitro fertilization …

STUDY QUESTION What is the accuracy of preimplantation genetic testing for aneuploidies
(PGT-A) when considering human peri-implantation outcomes in vitro? STUDY ANSWER …

Objective To understand the clinical risks associated with the transfer of embryos classified
as a mosaic using preimplantation genetic testing for aneuploidy. Design Analysis of data …

Developmental arrest of the preimplantation embryo is a multifactorial condition,
characterized by lack of cellular division for at least 24 hours, hindering the in vitro …

The detection of chromosomal aneuploidies and mosaicism degree in preimplantation
embryos may be essential for achieving pregnancy. The aim of this study was to determine …

Purpose This paper aims to investigate the efficacy of IVF with preimplantation genetic
testing for aneuploidy (PGT-A), using only best-scoring blastocysts from young (≤ 35 years) …

Abstract STUDY QUESTION In PGS, does chromosomal constitution differ among
trophectoderm (TE) biopsy sites and between them and the inner cell mass (ICM) …

Purpose This study evaluated the potential viability of embryos with low mosaicism level (<
50%) by comparing the clinical outcomes of single mosaic versus euploid blastocyst …
