Mark is interviewed on “The Project”, discussing IVF and genetic testing of embryos using the technique of Comparative Genomic Hybridization (CGH). This interview was conducted when Genea was presenting its first results from the technique.

Pre-implantation genetic diagnosis (PGD) is a process whereby cells are taken from an early embryo cell ball, the cells are then analysed for their chromosome complement using the CGH technique. Random errors in chromosome number are the commonest reason as to why human embryos fail to implant, or those that implant but then lead to miscarriage.

Who benefits from CGH? Probably not every IVF patient – but older women (whose older eggs are more likely to give rise to random chromosome errors in embryos) and women who suffer from repeated miscarriage of unknown cause may particularly benefit from this procedure.
