 The central argument in favor of reproductive cloning is expansion of opportunities for reproduction. Reproductive cloning could offer a new means for prospective parents to satisfy their reproductive goals or desires. Infertile individuals or couples could have a child that is genetically related to them. In addition, individuals, same sex couples, or couples who cannot together produce an embryo would no longer need donor gametes to reproduce if cloning were available (some might still need donor eggs for the cloning procedure, but these would be enucleated so that only the mitochondrial DNA remains). It would then be possible to avoid that one’s child shares half of her nuclear DNA with a gamete donor.
