We evaluated the clinical efficacy of the transport fresh embryo frozen-thawed embryo transfer method, whereby fresh embryos are transported from the satellite center for cryopreservation at the main ART center. In the Transport group (T group), surplus embryos from the satellite center were transported to the main ART center for frozen-thawed embryo transfer in 28 cycles in 15 patients. In the Center group (C group), oocytes were collected for frozen-thawed embryo transfer at the main ART center in 256 cycles in 165 patients. The slow freezing method was used. No significant differences were seen between groups in rates of embryo viability, embryo transfer, pregnancy, IVF embryo viability, ICSI embryo viability, pronuclear phase embryo viability, and cleavage phase embryo viability, or the numbers of transferred embryos. The transport fresh embryo frozen-thawed embryo transfer method is suitable for clinical application because there were no adverse effects from either transport or freeze/thawing.
