Issues related to the use of genetic engineering in therapy and enhancement are currently attracting public attention. The sports community has promptly responded to these questions, for example, by holding a workshop on genetic doping in 2002. Although doping technology and the underlying medical and scientific techniques have been evolving rapidly, their ethical aspects have not yet been discussed in sufficient depth. In this study, we clarified the specific ethical problems inherent in genetic doping by examining the ethical problems surrounding genetic engineering and genetic doping. In addition, we focused on the moral status of genes to discuss whether we should allow their manipulation, a fundamental theme of research in genetic engineering.
