CGH ( cytogenetic comparative hybridization) is in its infancy worldwide and has only recently come to the fore. It is still very expensive due to the research phase that it is going through and has a while to go still before becoming commercially available. Due to the technical difficulties it will not be available everywhere in the world, but rather at larger dedicated centres with a dedicated genetics facility. The research is mainly being conducted in the U.K. and the U.S. and presently, and for a while still, will not be available locally.

“Failure to implant” is every fertility unit’s nightmare. 70% of the reasons for non implantation is usually due to embryo quality and the other 30% is made up of uterine and immunological factors such as anti nuclear factor, anti phospholipids syndrome, HLA incompatibility and chromosomal defects in either the male or female partner.CGH is a new kid on the block and should be generally commercially available in a year or two. It is a very exciting development in the world of IVF/ICSI and we all hope for it to be the proverbial “holy grail” of ART.I am not aware of any clinics in South Africa that can offer this technology at the time of writing this response and only know of a few units in the rest of the world at this stage.
