Most embryos with chromosomal anomalies do not implant and those that do often miscarry during the first trimester of pregnancy.

Pre-implantation genetic screening improves IVF success because it identifies the embryos which have the correct number of chromosomes and are likely to develop a healthy pregnancy.
