Active Comparator: Blastocyst cryopreservation
Subjects randomly assigned to this arm of the study will have all of their embryos cryopreserved at the blastocyst stage, followed by thaw and transfer in a subsequent menstrual cycle.
Procedure: Blastocyst cryopreservation
Embryos cryopreserved at the blastocyst stage
Experimental: Bipronuclear oocyte cryopreservation
Subjects randomly assigned to this arm of the study will have all of their bipronuclear oocytes cryopreserved, followed by thaw, extended culture, and transfer in a subsequent menstrual cycle.
Procedure: Bipronuclear oocyte cryopreservation
Bipronuclear oocyte cryopreservation.
