Abstract

Researchers seek government support for “three-parent IVF” in the United Kingdom, for the purpose of bringing to clinical practice new techniques for avoiding inherited mitochondrial diseases. The author describes the development and processes of pronuclear transfer and maternal spindle transfer and offers an ethical evaluation of this cutting-edge science in light of the Church’s teaching in Dignitas personae. Promoting a eugenic mentality, both pronuclear transfer and maternal spindle transfer involve a radical manipulation of the human genome, inherited from three parents and passed on to future generations. Pronuclear transfer and maternal spindle transfer are immoral, because they represent an offense to marriage and the marital act and involve the destruction of innocent human life.
