During the past three decades, several technologies have been developed that allow medical professionals to assess the physical status of the foetus during a woman’s pregnancy. On the one hand, it has been argued that use of these technologies can be reassuring for parents who worry that their child may have a certain genetic disease. They can receive knowledge on which to base decisions of whether to carry the pregnancy to term. It has also been argued that those who know that they are at risk of a certain genetic disease and who, therefore, dare not try for pregnancy may dare to do so thanks to the availability of these technologies. On the other hand, uses of the technologies have also been criticised for imposing psychological burdens (Hildt 2002), particularly on women (Lippman 1998). Today, technologies are not only available for assessment of the prenatal physical status of the foetus but also for the genetic diagnosis of the embryo.
