Description: This book provides a clear and simple account of the techniques involved in assisted reproduction and embryo research, and discusses the legal and ethical implications of some of these technologies, illustrated by compelling descriptions of real-life cases. The book also addresses the ways in which reproductive technologies are regulated, critically examining the role of the Human Fertilization and Embryology Authority and comparing the UK's approach with that of other countries. Finally, it contemplates the possibility that some of our most deeply-held assumptions about human nature may be called into question by further developments in stem cell research and fertility treatments.
