Single Embryo Transfers and Embryo Glue

Our aim is to help you achieve a healthy baby and the best way to do this is by transferring a single embryo. When more than one embryo is transferred, there is a high chance of having a multiple pregnancy that is not ideal for baby and mum. People think that by putting only one embryo back this decreases their chances of having a baby but the scientific evidence does not support this.

Research shows that by transferring a single embryo at the blastocyst stage (day 5 of embryo development) it not only increases your chance of having a baby, it reduces the time to pregnancy. This is because not all embryos can reach the blastocyst stage for various biological reasons and by culturing in a robust, state of the art culture system, we can select the best embryo without compromise.

We also use Embryo Glue as a standard practice for all of our embryo transfers to give you the best chance of implantation. Embryo Glue is rich in a protein called hyaluronan which has been demonstrated to be an important factor in the implantation process³.
