The “holy grail” of in vitro fertilization is identifying a single embryo that produces a healthy baby. Currently, we have the ability to select a single euploid embryo for transfer. This can be achieved without harming the embryo if the biopsy is done at the blastocyst stage. Blastocysts can be frozen with high survival rates and then transferred in a thaw cycle. The implantation of frozen thawed embryos has been shown to be superior to those transferred into an endometrium that is under the influence of the stimulated environment.
