Genetic Screening and Its Role in Embryo Selection for IVF

Genetic screening plays a crucial role in the process of embryo selection for in vitro fertilization (IVF) by identifying potential genetic disorders in embryos before implantation. This screening, often referred to as preimplantation genetic testing (PGT), involves analyzing embryos for...

• Genetic testing, specifically preimplantation genetic testing (PGT), is used to diagnose embryos before implantation to avoid transferring embryos with DNA damage. It began focusing on inherited disorders but has expanded to encompass genetic screening for chromosomal abnormalities, potentially improving IVF outcomes. Selecting the best embryo involves multiple factors, including morphological assessment, cell symmetry, fragmentation, cell division, kinetics, blastocyst development, and time-lapse imaging, to maximize pregnancy success and minimize multiple pregnancies.
