"This brief textbook of human development covers the events of fertilization, gestation, and sex determination, followed by descriptions of the science of cloning, stem cells, and genome sequencing. The chapter covering the science is juxtaposed with a chapter discussing ethical questions that arise, such as when does life begin, should assisted reproductive technologies be regulated, and should parents be allowed to choose their child's sex"--Provided by publisher.

Human embryo research touches upon strongly felt moral convictions, and it raises such deep questions about the promise and perils of scientific progress that debate over its development has become a moral and political imperative. From in vitro fertilization to embryonic stem cell research, cloning, and gene editing, Americans have repeatedly struggled with how to define the moral status of the human embryo, whether to limit its experimental uses, and how to contend with sharply divided public moral perspectives on governing science. Experiments in Democracy presents a history of American debates over human embryo research from the late 1960s to the present, exploring their crucial role in shaping norms, practices, and institutions of deliberation governing the ethical challenges of modern bioscience. J. Benjamin Hurlbut details how scientists, bioethicists, policymakers, and other public figures have attempted to answer a question of great consequence: how should the public reason about aspects of science and technology that effect fundamental dimensions of human life? Through a study of one of the most significant science policy controversies in the history of the United States, Experiments in Democracy paints a portrait of the complex relationship between science and democracy, and of U.S. society's evolving approaches to evaluating and governing science's most challenging breakthroughs.

How does one make decisions today about in vitro fertilization, abortion, egg freezing, surrogacy, and other matters of reproduction? This book provides the intellectual and emotional intelligence to help individuals make informed choices amid misinformation and competing claims. Scott Gilbert and Clara Pinto-Correia speak to the couple trying to become pregnant, the woman contemplating an abortion, and the student searching for sound information about human sex and reproduction. Their book is an enlightening read for men as well as for women, describing in clear terms how babies come into existence through both natural and assisted reproductive pathways. They update “the talk” for the twenty-first century: the birds, the bees, and the Petri dishes. Fear, Wonder, and Science in the New Age of Reproductive Biotechnology first covers the most recent and well-grounded scientific conclusions about fertilization and early human embryology. It then discusses the reasons why some of the major forms of assisted reproductive technologies were invented, how they are used, and what they can and cannot accomplish. Most important, the authors explore the emotional side of using these technologies, focusing on those who have emptied their emotions and bank accounts in a valiant effort to conceive a child. This work of science and human biology is informed by a moral concern for our common humanity.

The Human Embryo in vitro explores the ways in which UK law engages with embryonic processes under the Human Fertilisation and Embryology Act 1990 (as amended), the intellectual basis of which has not been reconsidered for almost thirty years. McMillan argues that in regulating 'the embryo' – that is, a processual liminal entity in itself - the law is regulating for uncertainty. This book offers a fuller understanding of how complex biological processes of development and growth can be better aligned with a legal framework that purports to pay respect to the embryo while also allowing its destruction. To do so it employs an anthropological concept, liminality, which is itself concerned with revealing the dynamics of process. The implications of this for contemporary regulation of artificial reproduction are fully explored, and recommendations are offered for international regimes on how they can better align biological reality with social policy and law.

Scientists and philosophers have long struggled to answer the questions of when human life begins and when human life has inherent value. The phenomenon of identical (monozygotic) twinning presents a significant challenge to the view that human life and human personhood begin at conception. The fact that a single embryo can split to generate two (or more) genetically identical embryos seems to defy the notion that prior to splitting an embryo can be a single human individual. In Untangling Twinning, Maureen Condic looks at the questions raised by human twinning based on a unique synthesis of molecular developmental biology and Aristotelian philosophy. She begins with a brief historical analysis of the current scientific perspective on the embryo and proceeds to address the major philosophic and scientific concerns regarding human twinning and embryo fusion: Is the embryo one human or two (or even more)? Does the original embryo die, and if not, which of the twins is the original? Who are the parents of the twins? What do twins, chimeras, cloning, and asexual reproduction in humans mean? And what does the science of human embryology say about human ensoulment, human individuality, and human value? Condic's original approach makes a unique contribution to the discussion of human value and human individuality, and offers a clear, evidence-based resolution to questions raised by human twinning. The book is written for students and scholars of bioethics, scientists, theologians, and attorneys who are involved in questions surrounding the human embryo.

Strategies or decisions aimed at affecting, in a manner considered to be positive, the genetic heritage of a child in the context of human reproduction are increasingly being accepted in contemporary society. As a result, unnerving similarities between earlier selection ideology so central to the discredited eugenic regimes of the 20th century and those now on offer suggest that a new era of eugenics has dawned. The time is ripe, therefore, for considering and evaluating from an ethical perspective both current and future selection practices. This inter-disciplinary volume blends research from embryology, genetics, philosophy, sociology, psychology, and history. In so doing, it constructs a thorough picture of the procedures emerging from today's reproductive developments, including a rigorous ethical argumentation concerning the possible advantages and risks related to the new eugenics.
