If you use donor eggs, preimplantation genetic diagnosis (PGD) is not required, as the hereditary factor disappears when donor eggs are used. Also, it should be taken into account that donors are young women, so the chances for their eggs to carry a genetic abnormality associated with advanced maternal age are very low.
Down syndrome runs in my family, can I pass it to my offspring despite using donor eggs?
