Cloning is in this respect no different from any other new medical technology. Research is required on embryos in order to quantify and reduce the risk of the procedures. Embryo research is permitted in Britain until the fourteenth day of embryo development. Many other Western countries are also actively engaged in embryo research. The thousands of ‘spare’ embryos generated each year by IVF procedures and destroyed could be used to the good purpose of human cloning research. It should be noted that cloning has come a long way since dolly in 1997. In 2008 Japanese scientists managed to create clones from the bodies of mice which had been frozen for 16 years.
