The risk of a congenital abnormality after treatment using donor eggs is believed to be the same as for natural conception in a normal couple that is approximately 1 – 2%. The risk of having a child with Down’s syndrome and other similar abnormalities, miscarriage or a still birth as a result etc is that in the donor’s age group in the normal population. GP’s and those responsible for the obstetric care (obstetricians and midwives) routinely advise the recipient couples about prenatal diagnostic tests as appropriate.
