Study Summary

The purpose of this study is to compare the live birth rates of high concentration of Hyaluronic Acid (0.5 mg/ml) transfer medium (EmbryoGlue®) to those containing low Hyaluronic Acid concentrations (0.125 mg/ml) (G2 medium) in women undergoing single fresh and frozen blastocyst transfer.

Study Description

The single blastocyst-stage embryo transfer cycles will be randomised in a 1:1 allocation, with block sizes of 2 and 4 on the day of Embryo Transfer (ET). This randomisation process will be centrally managed via a web-based electronic data capture system and will be stratified according to the treatment center. The allocation sequence and the designated treatment will be completely concealed from the participating couples, clinicians - including those conducting the transfer procedures - and outcome assessors. Given the intrinsic viscous nature of EmbryoGlue, embryologists, who who are responsible for the procedures in the laboratory will not be subjected to blinding. Only at the end of the study, when data collection is completed, the allocation sequence will be revealed to the primary investigators.
