Array Comparative Genomic Hybdridization (aCGH) is technology that allows comprehensive gen screening before the embryo transfer to help selection of appropriate embryos.
Most of hereditary diseases are caused by genetic defects or abnormalities in chromosomes. Advanced technology led to a major development regarding diagnosis of genetic diseases. Now, it is possible to screen the entire genome quickly with a series of CGH (aCHG) methods to determine chromosomal diseases and imbalances.
aCGH ensures that all chromosomes (24 chromosomes) are examined and the healthiest embryo is selected for embryo transfer. Thus, pregnancy rates can increase. Moreover, this method can detect numerous chromosome damages that cannot be identified with another screening method, namely FISH.
