Embryo 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...

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 ...

Methods 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...

P-203: The Impact of Low-Dose Aspirin on Clinical Reproductive Outcomes in Frozen- Thawed Embryo Transfer Cycles; A Randomized, Placebo-Controlled Double- Blind Study

Background: The objective of this study is to evaluate whether low-dose aspirin affects doppler sonographic parameters of the uterine arteries, endometrial thickness and pregnancy rate of women undergoing frozen-thawed embryo transfer cycles. Materials and Methods: This randomized, double- blind, placebo-controlled trial study was conducted between April 2012, and March 2013. A total of 60 elig...
