Medically assisted reproduction and ethical challenges.
Many of the ethical challenges associated with medically assisted reproduction are societal. Should the technique be restricted to only ordinary couples or could it be used also to single females or couples of same sex? Should the future child be entitled to know the identity of the gamete donor? Should there be age limits? Can embryos or gametes be used after the death of the donor? Can surrogate mothers be part of the process? Can preimplantation diagnostics be used to select the future baby's sex? In addition, there are several clearly medical questions that lead to difficult ethical problems. Is it safe to use very premature eggs or sperms? Is the risk for some rare syndromes caused by imprinting errors really increased when using these techniques? Do we transfer genetic infertility to the offspring? Is the risk for multiple pregnancies too high when several embryos are implanted? Does preimplantation diagnosis cause some extra risks for the future child? Should the counselling of these couples include information of all these potential but unlikely risks? The legislation and practices differ in different countries and ethical discussion and professional guidelines are still needed.
