Preimplantation genetic diagnosis as an alternative to amniocentesis and chorionic villus sampling: psychosocial and ethical aspects.
Social and ethical considerations play an increasing role in decisions about the use of diagnostic technologies. In this article expert opinions of a medical-biological and a social-ethical panel on psychosocial, ethical and social aspects of preimplantation genetic diagnosis (PGD) are discussed. PGD is a new diagnostic technology for identifying chromosomal or single gene defects, which is now available as a medical treatment in several western countries. In contrast to traditional technologies like amniocentesis and chorionic villus sampling PGD offers the possibility for diagnosis before pregnancy. The panels expected PGD to be chosen only in serious situations. IVF was considered to be a barrier for PGD but less so in more serious situations. Destruction of pre-embryos was thought more acceptable than selective abortion, but only marginally. Finally a substantial decrease was expected in the acceptance of handicapped people in society as a consequence of the possibilities of technologies like PGD. Although PGD offers new possibilities for couples at risk of having a child with a genetic defect, it is important that couples are counseled in a way that emphasizes both the advantages and disadvantages of the technology. The general public should be informed about possibilities and impossibilities of preventive diagnosis and the right of future parents not to use genetic diagnosis.
