title: Preimplantation genetic diagnosis: technological promise and ethical perils.
abstract: OBJECTIVE
  To describe the ethical issues inherent to the current and foreseeable uses of preimplantation genetic diagnosis (PGD).
  
  
  METHODS
  Review of ethical principles and their application to PGD.
  
  
  METHODS
  Academic medical center.

  METHODS
  A discussion of the current ethical perils surrounding the use of PGD, and a prediction of future ethical quandaries that will arise from the use of this technology.
  
  
  RESULTS
  Although PGD may be used to predict and prevent disease, it may also be used to determine nondisease traits. The ever-expanding ability of genetics to determine qualities of the preimplantation embryo continues to open up new ethical questions relating to the use of PGD for preimplantation diagnosis.
  
  
  CONCLUSIONS
  Preimplantation genetic diagnosis is a powerful technique with many positive applications. As with all such new technologies, care should be taken to ponder the ethical implications of its use before routinely accepting PGD as a tool in the reproductive armamentarium.
