Preimplantation Genetic Diagnosis

Preimplantation Genetic Diagnosis is a technique used to identify genetic defects in embryos created through IVF before pregnancy. The process consists of taking a biopsy of an embryo cell (blastomere) on the third day and submitting it to several genetic anomaly detection tests. This is a specialized procedure performed by qualified professionals under a powerful microscope, using a hollow glass needle to penetrate the outer cover of the embryo and eliminate a single cell.

Preimplantation genetic screening (PGS) for aneuploidy is a powerful genetic test that may be performed on embryos during IVF treatment to screen for numerical chromosomal abnormalities. Alterations in the chromosome endowment can lead to failure of implantation in cycles of assisted reproduction, spontaneous abortions and chromosomopathies in newborns.

This test is usually when one or both of the genetic parents has a known genetic abnormality.

The PGS for chromosomal abnormalities allows to select those chromosomally normal embryos of all the evolutionary embryos of a patient, which increases their reproductive possibilities. Embryos that are chromosomally normal are more likely to evolve properly and result in a healthy child.
