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 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...
متن کاملCan letrozole plus HMG protocol improve pregnancy outcomes in frozen-thawed embryo transfer? An RCT
BACKGROUND There are different methods in endometrial preparation for frozen-thawed embryo transfer (FET). OBJECTIVE The purpose of this study was to compare the live birth rate in the artificial FET protocol (estradiol/ progesterone with GnRH-agonist) with stimulated cycle FET protocol (letrozole plus HMG). MATERIALS AND METHODS This randomized clinical trial included 100 women (18-42 year...
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...
