Question 9

One technology that has been valuable for couples who have a known increased risk of passing on a genetic disease (biochemical or chromosomal)is preimplantation genetic diagnosis (PGD).Ethically,some individuals feel this is "playing God" and should not be done; others consider the method a "scientific miracle" and are grateful for the opportunity to virtually insure that they will not have a disease-stricken child.Where would you fall on this spectrum of varying opinions? What factors have you considered in forming your opinion? Now suppose that you and your spouse are interested in starting a family but find out that the female (you or your spouse)is a carrier for Hunter syndrome,a genetic disorder in which the affected infants become blind,deaf,mentally retarded,and seldom live past age 5.Does this change your opinion of using PGD to select for a healthy child? Explain.
