RT Journal Article SR Electronic T1 Extending preimplantation genetic diagnosis: medical and non-medical uses JF Journal of Medical Ethics JO J Med Ethics FD BMJ Publishing Group Ltd and Institute of Medical Ethics SP 213 OP 216 DO 10.1136/jme.29.4.213 VO 29 IS 4 A1 J A Robertson YR 2003 UL http://jme.bmj.com/content/29/4/213.abstract AB New uses of preimplantation genetic diagnosis (PGD) to screen embryos prior to transfer raise ethical, legal, and policy issues that deserve close attention. Extensions for medical purposes, such as to identify susceptibility genes, late onset disease, and human leukocyte antigen (HLA) matching, are usually ethically acceptable. Whether embryo screening for gender, perfect pitch, or other non-medical characteristics are also acceptable depends upon the parental needs served and the harm posed to embryos, children, and society. Speculations about potential future uses of PGD should not prevent otherwise acceptable current uses of PGD.
