27. Blastocyst comprehensive screening and single-embryo transfer

After a comprehensive chromosome testing a single best embryo can be transferred in women. The initial data collected has revealed that frozen embryo transfer after comprehensive gene testing leads to a better on going pregnancy rates as compared to a fresh blastocyst transfer that was screened only morphologically [25, 26]. With the development of newer modalities like comprehensive chromosome screening and single embryo transfer older women will benefit and risks of multiple embryo transfer will be minimized.
