Diverging guidelines and consensus statements on preimplantation genetic testing for aneuploidy: indications and strategies reviewed

The authors aim to assess the consistency and standardization of preimplantation genetic testing for aneuploidy (PGT-A) practices by comparing recommendations from various authoritative guidelines and position statements. They identify both areas of consensus, such as advanced maternal age as a primary indication for PGT-A, and significant divergences in other indications and methodologies, highlighting the challenges posed by the rapid evolution of medical knowledge and the lack of robust evidence-based recommendations.
