The number of embryos to transfer to a patient is not dependent on the technique performed for the genetic analysis of embryos, but on the stage, quality, and particularities of each patient. Preimplantation Genetic Diagnosis is usually performed in cases of advanced maternal age (aneuploidy screening) or when there exist severe genetic pathologies (in many cases, present in the woman). In both situations, a multiple pregnancy would be contraindicated.
So, given all these circumstances, doctors usually recommend Single Embryo Transfers (SETs).
