In the light of recent strides made in the field of biomedical research, this document aims to address a range of issues including stem-cell therapies, embryo experimentation and infertility treatments. It reaffirms the Vatican's existing teachings, Donum Vitae (1987) and Evangelium Vitae (1995), and addresses new bioethical questions about issues such as hybrid embryos and cloning. Dignitas Personae focuses on the dignity of the human embryo, and promotes biomedical research that is respectful of the dignity of every human being and of human procreation.
