Diagnosis takes place using the array CGH method, which is capable of screening all 46 chromosome.

Target for Preimplantation Genetic Screening

• Numerical chromosomal abnormalities
• Advanced age in the prospective mother
• Recurrent pregnancy loss
• Repeated failure of implantation
• Oligozoospermia
• Prior pregnancy with a chromosome abnormality
