Arm Description
ovarian stimulation, oocyte aspiration, embryo culture until the blastocyst stage (day 5/6), TE biopsy, vitrification of all embryos in the blastocyst stage, PGT-A by NGS and finally embryo transfer of genetically normal embryos in cumulative frozen-thawed embryo transfer cycles
ovarian stimulation, oocyte aspiration, embryo culture until the blastocyst stage, fresh embryo transfer of the morphologically best embryo on day 5/6, vitrification of supernumerary embryos and embryo transfer in cumulative frozen-thawed embryo transfer cycles if not pregnant from the fresh cycle.
