Frozen-thawed embryo transfer cycles
In order to reduce the chance of multiple pregnancy during in-vitro fertilisation (IVF)– embryo transfer treatment, there is an increasing trend towards transferring a lower number of embryos. Surplus good-quality embryos are then transferred in frozen-thawed embryo transfer (FET) cycles. The first pregnancy after FET was reported in 1983.1 It has been estimated that in IVF programmes in which ...
متن کاملMethods for endometrial preparation in frozen-thawed embryo transfer cycles.
Frozen-thawed (FT) embryo transfer is a procedure used for the storage and transfer of excess embryos obtained during in vitro fertilization- intracytoplasmic sperm injection cycles. In recent years, improvements in laboratory conditions and limitations on the number of embryos to be transferred have led to a progressive increase in FT embryo transfer cycles. However, the best solution for endo...
متن کاملEmbryo stage of development is not decisive for reproductive outcomes in frozen-thawed embryo transfer cycles
OBJECTIVE To evaluate if the outcomes of IVF/ICSI in frozen-thawed embryo transfer and fresh embryo transfer cycles differ in relation to cleavage and blastocyst stages. METHODS Retrospective cohort study to compare IVF/ICSI outcomes between fresh embryo transfer and frozen-thawed embryo transfer cycles, according to the stage of embryo development. Analysis was carried out on 443 consecutive...
متن کاملO-23: Transfer of Blastocysts Derived from Frozen Thawed Cleavage Stage Embryos Improved Ongoing Pregnancy
Background: The aim of our study was to compare the resulting from transfer of embryos that cryopereserved in cleavage stage after thawing and transfer of embryos after thawing and culture in sequentional media until blastocyst formation. Materials and Methods: In this prospective clinical study, we have evaluated 128 cycles in women undergone in vitro fertilization (IVF) or intracytoplasmic sp...
متن کاملBlastocyst transfer in frozen-thawed cycles
OBJECTIVE It is well known that fresh blastocyst transfer results in better pregnancy outcomes with a smaller number of transferred embryos compared with cleavage stage embryo transfer. However, in terms of frozen-thawed blastocyst transfer, only a few studies are available. We aimed to evaluate clinical outcomes of frozen-thawed embryo transfer (FET) with blastocysts. METHODS Retrospective a...
