The possibility of embryo adoption has existed for over two decades and raises some questions that people really do not know how to answer. Over half a century ago, when the first child conceived through in vitro fertilization was born, Cardinal Albino Luciani, who within days would become Pope John Paul I, publicly welcomed her into the world without endorsing artificial fertilization. Today, there are over one million frozen embryos in cryostorage in the United States, and the question in Dignitas personae 19 on “what to do with them” is still unresolved. The legal status of the human embryo should be a person – some states have passed laws pertaining to this – but there is still a great deal of confusion about the morality of both embryo transfer and embryo adoption. This book was written in the hope of clarifying some of the ethical issues in the search for a moral solution.
