EmbryoGlue® is an implantation-enhancing medium that contains high amounts of albumin and hyaluronic acid. Albumin, a globular protein found in abundance in the female reproductive system, serves as a source of energy to a growing embryo, supplying it with critical vitamins, metals, and hormones. Hyaluronic acid is found in the fallopian tubes and uterus and promotes angiogenesis—the generation of new blood vessels—following implantation. Both are essential to the health and development of the blastocyst following transfer. Due to its high viscosity, EmbryoGlue® also facilitates retainment of the embryo in the uterus.
