[To design "the baby one wishes for" is theoretically possible. Ethical issues in preimplantation diagnosis must be defined]

Abstract

Preimplantation genetic diagnosis (PGD) is a controversial method: while it prevents genetic disorders it is also said to have a eugenic side. It gives rise to many questions: What are the ethical differences between PGD and prenatal postimplantation diagnosis? Is PGD an ethically justifiable method? The conclusion is that PGD is to be preferred to prenatal diagnosis for couples who are at high risk of giving birth to children with very serious genetical diseases with an early onset.
