Preimplantation Genetic Screening (PGS) is a procedure designed to examine embryos for chromosomal abnormalities with the aim of de-selecting embryos with low implantation potential. Preimplantation genetic diagnosis (PGD) refers to genetic diagnosis of embryos prior to transfer in cases with a known inherited disorder. Vitrolife has conducted a survey within the IVF community to determine how wide spread the use of these procedures actually is in the everyday routines. The results will be shared in this blog post.
