The status of preimplantation genetic diagnosis in Japan: a criticism

Advances in preimplantation genetic diagnosis (PGD) are occurring worldwide. New clinics specializing in this approach to the control of disease genes or imbalanced chromosome numbers in human preimplantation embryos continue to increase. One exception is Japan, where the Japanese Society of Obstetrics and Gynecology disapproves of this practice because it discriminates against people with genetic abnormalities. Yet, some doctors there wish to introduce this method to help their couples to improved forms of IVF. This paper stresses the rights of patients to have a healthy baby, if necessary by the use of PGD. It argues against prohibition, since it complements the current nature of prenatal diagnosis and avoids the need for abortions in case of afflicted embryos. Consideration is also given to other attempts at restriction that have failed.
