Abstract
Designed to minimize chances of transferring genetically abnormal embryos, preimplantation genetic diagnosis (PGD) involves
(PGT-A) aims to avoid miscarriage and live born trisomic offspring and to improve IVF success. Diagnostic approaches include
comparative genomic hybridization (aCGH), quantitative polymerase chain reaction (PCR), next-generation sequencing (NGS) and
simultaneously. Mosaicism (commonplace in human embryos) can arise by several mechanisms; those arising initially meiotically (but
are initially chromosomally normal (but then arise purely post-zygotically) can lead to unaffected live births is uncertain. Polar body
Historically, cleavage-stage (blastomere) biopsy has been the most popular; however, higher abnormality levels, mosaicism and
analysis. Improved biopsy, diagnosis and freeze-all strategies collectively have the potential to revolutionize PGT-A, and there is
consider the evidence base sufficient to justify routine PGT-A? Basic biological research is essential to address unanswered questions
more. This will benefit both IVF patients and prospective parents at risk of aneuploid offspring following natural conception. The aim
forward’ in terms of future diagnosis and applied research.
