 With the actual rate of advancement in cloning, one cannot exclude a future in which the safety and efficiency of SCNT will be comparable or superior to that of IVF or even sexual reproduction. A remaining question is, then, whether those who condemn cloning because of its experimental nature should continue to condemn it morally and legally. Some authors have reasoned that if, in the future, cloning becomes safer than sexual reproduction, we should even make it our reproductive method of choice (Fletcher 1988; Harris 2004, Ch. 4).
