Three-Parent Babies or 2.001-parent Babies?: A Scientific and Bioethical Examination of Mitochondrial Replacement Therapy

This thesis critically examines the scientific and ethical dimensions of the novel and controversial technology of mitochondrial replacement therapy (MRT). The first portion provides a background on mitochondrial diseases and examines how these organelles (mitochondria) have left humans vulnerable to disease. The second portion of the thesis examines the technology of mitochondrial replacement therapy and what research contributed to the development of MRT. Finally, the third section responds to the ethical and legal concerns proposed and outlined by the Nuffield Council of Bioethics. After careful consideration of all legal and ethical concerns, it is concluded that the technology of MRT should be pursued under careful foresight with the idea that the technology is already happening and we must move forward in a way that provides the greatest information.
