This book offers a vision of politics that govern the womb; from antiquity ('be fertile and replenish the earth'), through the ages (hysterectomy, to extirpate women's 'hysteria'), up to the present time (abortion wars; assisted reproduction), and into the future (reprogenetics; the artificial womb). It explores how the womb has served humanity, either tacitly or explicitly, through the ages and examines how women have accepted and still perceive the rules created by men as natural - including the new anti-abortion laws in the USA - because 'that is the way things are.' The book also explores how the emerging of assisted reproduction technologies and novel genetic tools (reprogenetics) will pose additional challenges to womb bearers, as all women will be made to reproduce with IVF. What is more, the advent of the artificial womb is in sight; the gender and social implications of this development would be enormous. Certainly not just another organ, the womb has been and remains a powerful tool that cannot be left to the decisions of half of the population. This book engages a wide audience, including women and men, professionals and laypersons who are interested in gender, politics, legislation, women's health, and ethics.

This book presents the contemporary history and dynamics of Mexican midwifery - professional, (post)modern or autonomous, traditional and Indigenous - as profoundly political and embedded in differing societal stratifications. By situated politics, the authors refer to various networks, spaces and territories, which are also constructed by the midwives. By politically situated, the authors refer to various intersections, unsettled relations and contexts in which Mexican midwives are positioned. Examining Mexican midwiferies in depth, the volume sharpens the focus on the worlds in which midwives are profoundly immersed as agents in generating and participating in movements, alliances, health professions, communities, homes, territories and knowledges. The chapters provide a complex panorama of midwives in Mexico with an array of insights into their professional and political autonomy, (post)coloniality, body-territoriality, the challenges of defining midwifery, and above all, into the ways in which contemporary Mexican midwiferies relate to a complex set of human rights. The book will be of interest to a range of scholars from anthropology, sociology, politics, global health, gender studies, development studies, and Latin American studies, as well as to midwives and other professionals involved in childbirth policy and practice.

This volume comprehensively focuses on polycystic ovary, metabolic syndrome and obesity and their impact on women's health, reproduction and quality of life from adolescence to old age. PCOS is analyzed form the early origins - highlighting the importance of diagnosis, management and treatment starting from the high-risk period of adolescence - throughout infertility PCOS-related issues, pregnancy and menopause transition. All aspects of this syndrome are covered also in relation with endocrine and metabolic features that affects women's health. This book is a very useful tool for gynecologists, endocrinologists, obstetricians, reproductive medicine and general practitioners and is an important resource for all physicians involved in women's health.

Diverse Pathways to Parenthood: From Narratives to Practice is a timely contribution to the study of reproduction and parenthood. Drawing on a wide breadth of projects, this book covers topics such as first time parents, donor conception, pregnancy loss, surrogacy, lesbian, gay and/or transgender parenting, fostering and adoption, grandparenting, and human/animal kinship. By presenting individual narratives focused on reproduction and parenthood, this book successfully translates empirical research into practical, applied outcomes that will be of use for all those working in the fields of reproduction and parenthood. Including recommendations for fertility specialists, educators, child protection agencies, reproductive counselors, and policy makers, Diverse Pathways to Parenthood: From Narratives to Practice is a vital new resource that will help guide practice into the future. As a contribution to the field of critical kinship studies, this book heralds new directions for the study of kinship, by revisiting as well as reimagining how we think about, research, and respond to a diversity of kinship forms.

Sex matters! Are there differences between the sexes when it comes to brain function and the behaviours that result? This volume attempts to answer this fundamental question. If the answer is 'yes' then this should impact upon our approach to treating mental illness in humans, and to modelling it in animals, as we look for aetiological and pharmacological solutions.

This book discusses the role of oxidative stress in human reproduction with a focus on men's health. The physiological roles of reactive oxygen species (ROS) in male fertility are the focus in this book. This topic is important because oxidative stress is a result of the imbalance between ROS and antioxidants in the body which may lead to sperm damage (DNA or count), deformity, and eventually, male infertility. Therefore, for a better understanding of the molecular mechanisms related to male genotoxicity and its regulation in infertility, this book provides an up-to-date view on the impact of oxidative stress factors in male reproduction . The main aim of this book is to collect a series of research articles and reviews from a diverse group of scientists to share their research work on the role of ROS or oxidative stress in physiological and pathological states in relation to (in)fertility in the male. This book presents various state-of-the-art chapters of the recent progress in the field of cellular toxicology and clinical manifestations of various issues related to men's health and fertility. Topics include cell signaling, DNA damage and infertility, the pathophysiology of disease instigation and distribution, immune toxicity and prevention.

Congenital malformations are worldwide occurrences striking in every condition of society. These severe physical abnormalities which are present at birth and affecting every part of the body happen more often than usually realized, once in every 33 births. The most common, after heart defects, are those of the neural tube (the brain and spinal cord) which happen in as many as one in every 350 births. They have been noted as curiousities in man and beast throughout recorded history and received great attention in our time by various fields of study, for example, their faulty prenatal development by embryologists, familial patterns by geneticists, causation by environmentalists and variability by population scientists.

Attention turned much in recent years to the relation of these malformations to deficiency of a particular dietary ingredient, folic acid, a subject this book analyzes in depth. The greatest conundrum of all, which this latest matter like so much else hinges on, is the amazing fact of the tremendous, almost universal decrease in the frequency of these anomalies since early in the 20th century. The puzzle is 'What can this downward trend possibly mean?' and at bottom 'Whether it is part of a long-term cyclical pattern'. This fascinating biological phenomenon is explored in the book together with various other topics.

How the fear of malpractice affects mothers and reproductive choices Giving birth is a monumental event, not only in the personal life of the woman giving birth, but as a medical process and procedure. In The Business of Birth, Louise Marie Roth explores the process of giving birth, and the ways in which medicine and law interact to shape maternity care. Focusing on the United States, Roth explores how the law creates an environment where medical providers, malpractice attorneys, and others limit women's rights and choices during birth. She shows how a fear of liability risk often drives the decision-making process of medical providers, who prioritize hospital efficiency over patient safety, to the detriment of mothers themselves. Ultimately, Roth advocates for an approach that protects the reproductive rights of mothers. A comprehensive overview, The Business of Birth provides valuable insight into the impact of the law on mothers, medical providers, maternity care practices, and others in the United States.

This second edition offers an expanded and updated history of the field of fetal and neonatal development, allowing readers to gain a comprehensive understanding of the biological aspects that contribute to the wellbeing or pathophysiology of newborns. In this concluding opus of a long and prominent career as a clinical scientist, Dr. Longo has invited new contributions from noted colleagues with expertise in various fields to provide a historical perspective on the impact of how modern concepts emerged in the field of fetal physiology and contributed to the current attention paid to the fetal origins of diseases in adults. In addition to new chapters on maternal physiology and complications during pregnancy, others trace the history of the Society for Reproductive Investigation, governmental funding of perinatal research, and major initiatives to support training in the new discipline of maternal fetal medicine, including the Reproductive Scientist Development program. The extensive survey provided by the author, who personally knew most of the pioneers in the field, offers a unique guide for all clinical and basic scientists interested in the history of - and future approaches to diagnosing and treating - pathologies that represent the leading causes of neonatal mortality and, far too often, life-long morbidity.

Reproductive donation is the most contentious area of assisted reproduction. Even within Europe there are wide variations in what is permitted in each country. This multi-disciplinary book takes a fresh look at the practices of egg, sperm and embryo donation and surrogacy, bringing together ethical analysis and empirical research. New evidence is offered on aspects of assisted reproduction and the families these create, including non-traditional types. One of the key issues addressed is should children be told of their donor origin? If they do learn the identity of their donor, what kinds of relationships may be forged between families, the donor and other donor sibling families? Should donation involve a gift relationship? Is intra-familial donation too close for comfort? How should we understand the growing trend for 'reproductive tourism'? This lively and informed discussion offers new insights into reproductive donation and the resulting donor families.

This book is the first to bring together an interdisciplinary collection of essays on surrogacy and egg donation from three socially, legally and culturally distinct countries - India, Israel and Germany. It presents contributions from experts in the field of social and cultural sciences, bioethics, law as well as psychology and provides critical-reflective comparative analysis of the socio-ethical factors shaping surrogacy and egg donation practices across these three countries. This book highlights the importance of a comparative perspective to 'make sense' of controversies and transitions in this highly contested area of artificial reproductive technologies. It demonstrates how local developments cannot be isolated from global events and vice versa. Therefore, this volume can be used as a standard reference for anyone seeking to understand surrogacy and egg donation from a macro-perspective in the next decade.

This insightful and thought-provoking 2002 collection of chapters describes the rapid advances that had revolutionised reproductive medicine in the years leading up to its publication. This transformation was the result of converging and overlapping developments in reproductive biology, molecular biology and genetics. These advances allied with remarkable technical developments pushed the boundaries of this discipline ever faster forward. This volume surveys this rapid expansion as it stood in 2002 and looks ahead at exciting prospects for the future that stand at the watershed between basic science and clinical application. From oogeneis and spermatogenesis, through to fertilisation, embryogenesis and cloning, this volume looks at scientific advances. Subsequent chapters focus on infertility and its diagnosis and treatment using the full armory of assisted reproductive technologies. A concluding section surveys the impact of these developments on the provision, regulation and financing of reproductive health care in the global community.

Pre-eclampsia is one of the leading causes of death and disability in mothers and babies. Over four million women worldwide will develop the disorder every year. This book, written by an international team of experts, focuses on both the scientific basis of pre-eclampsia and its management. The basic science section contains reviews of the most exciting research developments in pre-eclampsia. The clinical chapters provide a comprehensive review of the pertinent literature, highlighting data and ideas or developments in management. There is a section in each chapter (where relevant) that deals with practical management, giving clinicians a formulated treatment plan that they can implement directly. The book was originally published in 2007, and will have continuing relevance for all professionals interested in the reproductive sciences, and to obstetricians and physicians with an interest in pre-eclampsia.

Enhancing Fertility through Functional Medicine: Using Nutrigenomics to Solve 'Unexplained' Infertility provides cutting-edge information and solutions to help support the worldwide rise of fertility challenges. It addresses common, yet not commonly known, root-causes of oxidative stress that are at the heart of reproductive issues (and all chronic health issues). These solutions can help enhance the outcomes of Assisted Reproductive Technologies (ART) or support women to avoid them altogether. Enhancing Fertility through Functional Medicine: Using Nutrigenomics to Solve 'Unexplained' Infertility will show you how to improve cell health (including egg and sperm), lower inflammation, balance nervous system functioning, and optimize genetic expression, allowing the body to return to its naturally fertile state. It details information on numerous root causes of health-derailing inflammation and oxidative stress, while the appendices discuss the genetic and biochemical pathways related to these topics. Each chapter also provides easy "Action Steps" that can be implemented immediately. Chapter topics include iron dysregulation; oxalates; mold/mycotoxins; phase 2 liver detoxification pathways; fat utilization; introductory information on genetics, epigenetics, and nutrigenomics; everything one needs to know about histamine intolerance; and how these factors adversely affect metabolic and reproductive functions. Enhancing Fertility through Functional Medicine: Using Nutrigenomics to Solve 'Unexplained' Infertility is the handbook for people wanting to achieve and sustain a healthy pregnancy. It highlights lesser-known causes of fertility challenges the reader can learn how to investigate. This book also serves as a reference guide for practitioners, providing them with additional tools to add to their repertoires when other protocols have not been effective. It may also provide clarity as to why other protocols did not work, and will enable the practitioner to custom-tailor protocols for each patient.

Reflecting the increasing interest in fertility management for pediatric and adolescent patients and fulfilling an urgent need to have a comprehensive guide to the management of these individuals, this is the first book of its kind to present a comprehensive discussion of pediatric and adolescent oncofertility. It carefully examines the impact of pediatric cancer and cancer therapy on fertility and presents both current and emerging fertility preservation techniques for both males and females, such as cryopreservation. Fertility concerns beyond cancer are also discussed, including disorders of sexual differentiation, gender dysphoria and thalassemia. Practical chapters on pediatric oncofertility in the clinic round out the book, covering setting up a practice, counseling and consent, disclosure and insurance considerations. Concluding chapters document fertility preservation techniques and outcomes internationally, with contributions from Portuguese, Brazilian and Japanese authors. Timely and wide-ranging, Pediatric and Adolescent Oncofertility is an ideal resource for reproductive medicine specialists, pediatric oncologists, and primary care physicians treating pediatric and adolescent cancer patients looking to protect fertility options.

This book focus on genetic diagnostics for Uniparental Disomy (UPD), a chromosomal disorder defined by the exceptional presence of a chromosome pair derived from only one parent, which leads to a group of rare diseases in humans. First the molecular and cytogenetic background of UPD is described in detail; subsequently, all available information of the various chromosomal origins and the latest findings on genotype-phenotype correlations and clinical consequences are discussed. Numerous personal reports from families with a child suffering from a UPD-induced syndrome serve to complement the scientific and clinical aspects. Their experiences with genetic counseling and living with a family member affected by this chromosomal aberration present a vivid picture of what UPD means for its victims.

The ideal of equality constitutes a criterion for assessing current practice through attention to differences among individuals and groups. Inequality occurs when irrelevant differences are invoked in order to secure power or advantages over others. This book examines health care issues from an egalitarian perspective, focusing particularly on those that affect the lives of women and children. These are some of the most hotly debated, controversial, yet genuinely humanitarian issues of our time. They include gender stereotypes in medicine and in adolescent socialization, fertility curtailment and enhancement, coercive treatment during pregnancy, fetal tissue transplantation, decisions regarding newborns, decision-making by minors, the feminization of poverty and its impact on women's and children's health, and the meaning and role of "family" in health care decisions. The book describes a case-based or "feminine" model of reasoning as appropriate to the health care setting, but also as a possible rationale for exploitation of women. Different versions of feminism are clearly explained and specifically related to care-based reasoning. To overcome the pitfalls of paternalism and excessive stress on patient autonomy, a concept of "parentalism" is defended. An egalitarian perspective, the author claims, involves use of one's power to empower others. Because of the timeliness of the topics discussed, and the depth of detail, this book will be necessary reading for all bioethicists, health-care analysts and policy-makers, and women's studies researchers.

The versatility of oocyte and embryo donation has proven to be extremely valuable to both patients and doctors engaged in reproductive medicine. Originally thought to be applicable only to a rather small subset of infertile women, today busy practices commonly recommend the procedure and it is estimated that nearly all of the 400 or more IVF programs in the United States provide these services. Oocyte and embryo donation has established itself as a mainstay procedure within assisted reproductive care, and the breadth, depth and complexity of practice is deserving of focused attention. Much has changed within the field of oocyte and embryo donation since the publication of the first edition of Principles of Oocyte and Embryo Donation in 1998, thus the need for a completely updated and more expansive text. The second edition of this book provides an overview of the major issues affecting men and women engaged in the practice of oocyte and embryo donation. A primary emphasis has been placed on defining the standards of practice that have evolved over the past 30 years, clearly stating the outcomes expected from adhering to these established protocols. Details of both the basic science and the clinical medicine are presented together and attention is also focused on the non-reproductive aspects inherent to this unique method of assisted reproduction that involves opinions from lawyers, ethicists, mental health care professionals and theologians. Oocyte and embryo donation requires a working knowledge of the medicine, the law and the ethics that underlies its foundation. This book is intended to serve as a complete and comprehensive reference for all health care professionals that provide services related to egg donation, reproductive endocrinologists, obstetrician- gynecologists, and fellows and residents entering the fertility field.

This book provides a comprehensive overview on issues surrounding fertility in patients who have been diagnosed with breast cancer or belong to a high-risk population. The impact of breast cancer treatment on fertility is clearly explained and all the available options for fertility preservation are discussed, including the use of assisted reproduction technologies. Guidance is offered on family planning and on management options when breast cancer arises during pregnancy and when pregnancy occurs after breast cancer. Answers are provided to a wide range of key questions, including: What is the impact of pregnancy after breast cancer on prognosis? What advice should be given on the timing of pregnancy in relation to chemotherapy and endocrine treatment? What is the effect of reducing the duration of endocrine treatment to allow an earlier attempt at pregnancy? Is breast feeding possible? Medical treatments of breast cancer have a huge impact on fertility. While many procedures can be applied to preserve fertility, all must be put into action within the very short time available before starting treatment. Any delay in referral of a woman wishing to preserve her fertility to an ART center with experience in oncologic patients may preclude the possibility of a future pregnancy. In addition, an increasing number of high-risk patients are asking questions about their reproductive life, from choice of contraception to the risks of assisted reproduction techniques. Physicians will find this book an invaluable aid in providing flawless counseling to their patients and ensuring that they receive optimal management.

Infertility Comics and Graphic Medicine examines women's graphic memoirs on infertility, foregrounding the complex interrelationship between women's life writing, infertility studies, and graphic medicine. Through a scholarly examination of the artists' use of visual-verbal codes of the comics medium in narrating their physical ordeals and affective challenges occasioned by infertility, the book seeks to foreground the intricacies of gender identity, embodiment, subjectivity, and illness experience. Providing long-overdue scholarly attention on the perspectives of autobiographical and comics studies, the authors examine the gendered nature of the infertility experience and the notion of motherhood as an ideological force which interpolates socio-cultural discourses, accentuating the potential of graphic medicine as a creative space for the infertile women to voice their hitherto silenced perspectives on childlessness with force and urgency. This interdisciplinary volume will be of interest to scholars and students in comics studies, the health humanities, literature, and women's and gender studies, and will also be suitable for readers in visual studies and narrative medicine.

In this third volume, the Biennial Review of Infertility brings together the most up-to-date research and clinical information on male and female infertility, emerging assisted reproductive techniques, and controversial issues in reproductive medicine. An impressive panel of contributors presents cutting-edge information in a clear and well-balanced manner. This volume includes hot topics in reproductive medicine including age and its impact on fertility, lifestyle factors and reproductive health, fertility preservation for cancer patients, reproductive tourism and a discussion of clinical research design. The expanded section on controversies allows for point/counterpoint discussion between experts with differing opinions on topics like safety of the ICSI procedure and the role of IUI in modern reproductive medicine. Created to provide an ongoing appraisal of current knowledge, the Biennial Review of Infertility stimulates communication amongst all those working to help couples resolve their infertility.

If you had a dependable method for determining the healthiest and most viable conceptus from a cohort of growing preembryos, replacing more than a single one in order to achieve good pregnancy rates would be moot. Sometime in the not-so-distant future, this may be a reality. Taking a step towards that future, An Atlas of Human Blastocysts vividly illustrates the typical and atypical morphology of mammalian blastocysts. The atlas demonstrates that extended culture of blastocysts is now achieveable in the laboratory and points us toward the day when it will be possible to choose between a number of healthy hatched blastocysts.
