EmbryoGen/ Blastgen for Couples With Implantation Problems or Previous Miscarriage

EmbryoGen and BlastGen contain the cytokine growth factor Granulocyte-Macrophage Colony-Stimulating Factor (GM-CSF), which has been documented to give significant benefit to this difficult group of patients. Results showed a highly significant effect of 44% relative improvement in ongoing implantation rate (p=0.001) in women who have previously miscarried (Ziebe et al 2013). We wish to undertake a randomised Controlled trial to determine if EmbryoGen/BlastGen media improves pregnancy outcomes in women with recurrent implantation failure, recurrent miscarriage and poor embryo development when compared to standard media.
