If the odds can't be improved in human embryos, it would require several surrogate mothers to insure that one clone was brought all the way to term, or multiple pregnancy attempts by a single woman. The U.S. government's National Bioethics Advisory Commission issued a report in 1998 calling for a voluntary ban on human cloning. Professional and scientific societies should make clear that any attempt to create a child by somatic cell nuclear transfer and implantation into a woman's body would at this time be an irresponsible, unethical, and unprofessional act. It took nearly 300 attempts before Dolly the sheep was born. Scientists don't know if cloned animals, let alone humans, will develop normally, or if they might be especially vulnerable to some diseases.
Cloning violates the religious values of many religions.
The controversy around human cloning is likely to keep any experiments out of the public limelight until someone has succeeded. The first human clone will likely be a fait accompli long before the ethical, moral or policy debate has reached a consensus. Shop O2 . All Rights Reserved.
