Impassable scientific, ethical and legal barriers to body-to-head transplantation.

This article consists of four parts. In the first part it briefly describes the history of body-to-head transplantation (BHT) and the surgical plan proposed by Drs. Sergio Canavero and Ren Xiaoping on a human subject. In the second part it argues that the BHT procedure that they propose is scientifically invalid and technically infeasible so therefore would end in failure. In the third part it argues that the present conceivable procedure of BHT cannot be ethically justified because it would bring great harm to the human subject, it is uncertain who would be the possible beneficiary, and valid informed consent cannot be obtained. In the fourth part it argues that the action of performing the procedure of BHT might violate China's current criminal and civil laws. The conclusion that follows from the arguments above is that BHT should be prohibited now and also in the near future. However, this conclusion does not preclude scientists, neurosurgeons and bioethicists doing research into scientific, technical, surgical and ethical issues raised by BHT.
