Pregnancies after transfer of ultrarapidly frozen human embryos
Journal of Assisted Reproduction and Genetics, 1996We report our experience of freezing human embryos using an ultrarapid freezing method.The patients were superovulated. Oocytes were inseminated and cultured in HTF + 10% serum. A maximum of three embryos was transferred and the rest of the embryos were frozen ultrarapidly after a 3-min equilibration period in PB1 + 3.5 M DMSO + 0.25 M sucrose. Embryos

Frozen embryo-transfer: a review on the optimal endometrial preparation
Minerva MedicaFrozen-thawed embryo transfer (FET) has become a widely adopted method in assisted reproductive technology (ART), thanks to the advancements in vitrification techniques. FET now accounts for a significant proportion of ART cycles, but there is still no clear consensus on the optimal protocol for endometrial preparation. This review aims to evaluate the

Fresh Versus Frozen Embryo Transfer
2019The fresh embryo transfer has traditionally performed in vitro fertilization (IVF) since 1978. The first pregnancy following the transfer of a frozen-thawed human embryo was reported in 1983. Since then, the clinical value of embryo cryopreservation has steadily increased over the decades. Improvements in vitrification now make frozen embryo transfer a
