Use of cryopreserved embryos in assisted reproductive technology programs
Overall success rates for cryopreserved embryo transfer have increased over the past few years. The paper gives data on the higher efficiency of cryo protocols versus fresh in vitro fertilization (IVF) protocols. It demonstrates the greater contribution of cryopreserved embryo transfer to the total number of live births over the past decades. Moreover, clinical and embryological tactics during the IVF program using cryopreserved embryos are not clearly defined. The effectiveness of assisted embryological techniques in the transfer of cryopreserved embryos has not been studied. There is a high variability in the protocols for preparing the endometrium for cryotransfer, including differences in dose, routes of administration, duration of use of drugs, and the first day of progesterone administration. Despite a large number of studies in this area, all of them are retrospective. In addition, the cost-effectiveness of the widespread use of cyclic hormone therapy has not been investigated. All of the above necessitates further study of this problem.Petrosyan Ya.A., Frolova A.M., Syrkasheva A.G.
