Arguments in favour of embryo research Prevention of congenital defects. Reduction in number of miscarriages. Better understanding of infertility. Arguments against embryo research Morally unacceptable to take potential human life. The 14-day limit on research is arbitrary. Fears about the creation of 'superspecies' and 'designer babies'. Fear of embryo 'trade' in which embryos are bought and sold.
