The genetic potential of embryos can be determined by PGT-A testing after a biopsy at the blastocyst stage. Approximately, 70-80% of donor eggs are euploid (healthy), hence these eggs have a high probability of producing euploid embryos. Yet sperm factor also has a direct effect on an embryos genetic potential.
At OVOGENE Egg Donor Bank our team created a unique method, known as “Genetically Certified Donor Egg”, where we are testing donor eggs by polar body biopsy with the PGT-A method. This has been shown to increase the chance of euploid blastocysts. Therefore, there is a higher probability a genetically healthy embryos.
