The central question of this book is whether or not particular cell entities of human origin ought to be considered human beings. The answer is crucial for making moral decisions for or against research and experimentation. Experts in the field discuss the production of embryonic-like pluripotent stem cells by altered nuclear transfer, parthenogenesis and reprogramming of adult somatic cells. They thoroughly analyse the biological and moral status of different cell entities, such as human stem cells, embryos and human-animal hybrid embryos, and make a decisive step towards establishing final criteria for what constitutes a human being. The topic is challenging in nature and of broad interest to all those concerned with current bioethical thought on embryonic human life and its implications for society.

This second edition emphasizes the environmental impact on reproduction, with updated chapters throughout as well as complete new chapters on species such as sharks and rays. This is a wide-ranging book that will be of relevance to anyone involved in species conservation, and provides critical perspectives on the real utility of current and emerging reproductive sciences.Understanding reproductive biology is centrally important to the way many of the world's conservation problems should be tackled. Currently the extinction problem is huge, with up to 30% of the world's fauna being expected to disappear in the next 50 years. Nevertheless, it has been estimated that the global population of animals in zoos encompasses 12,000 - 15,000 species, and we anticipate that every effort will be made to preserve these species for as long as possible, minimizing inbreeding effects and providing the best welfare standards available. Even if the reproductive biology community cannot solve the global biodiversity crisis for all wild species, we should do our best to maintain important captive populations. Reproductive biology in this context is much more than the development of techniques for helping with too little or too much breeding. While some of the relevant techniques are useful for individual species that society might target for a variety of reasons, whether nationalistic, cultural or practical, technical developments have to be backed up by thorough biological understanding of the background behind the problems.

Biological rhythms time the ebb and flow of virtually every physiological process, and their mutual coordination guarantees the integrity of the organism over space and time. Aging leads to the disintegration of this coordination, as well as to changes in the amplitude and/or frequency of the underlying rhythms. The results of this are accelerated loss of health during aging, and in experimental model systems curtailed lifespan occurs. This book will examine the machinery that constitutes circadian systems and how they impact physiologic processes. It will also discuss how disturbances of circadian rhythms can lead to complex diseases associated with aging. Much of this treatment will focus on metabolism and genome stability. Importantly, the chapters in this book will encompass work in several different models, in addition to human. The book will conclude with a discussion of modeling approaches to biologic cycles and chronotherapy, for future research and translation.

Providing the latest evidence-based information on etiology, evaluation and treatment, this unique text provides an in-depth, comprehensive discussion of the epidemiology, genetic and endocrinologic factors and medical and surgical management of recurrent pregnancy loss (RPL). Taking a multidisciplinary approach including psychological treatment and patient perspectives, all aspects of current RPL prevention and treatment are elucidated. Detailed chapters provide real-world illustrative material and cover the set-up and management of RPL clinics and databases, containing practical tips. Recurrent Pregnancy Loss will be an excellent resource for OB-GYN specialists, general and reproductive endocrinologists, radiologists, hematologists, psychiatrists, psychologists, and any other investigators or clinicians treating patients confronted with this emotionally and physically trying condition.

Epigenetics is a rapidly expanding field in medical and biological research which concerns heritable traits that are not attributable to changes in the DNA sequence. Epigenetic mechanisms play key roles in many biological processes, and it has become clear that their disruption can gives rise to diverse pathologies in humans. Edited by preeminent experts, Sophie Rousseaux and Saadi Khochbin, this volume in the Epigenetics and Human Health' series discusses the role of epigenetics in human reproduction. The book presents epigenetic transitions that are important at defined stages of gametogenesis and during meiosis. Several of the sixteen chapters written by experts in the field cover fundamental concepts discovered through cellular and biochemical work and from research on animal models. In other chapters, key examples are provided of how disruption of these mechanisms affects germ cell development and fertility, and contributes to the germinal cancers. Finally, the book discusses how in vitro manipulation and culture in assisted reproduction can epigenetically perturb germ cells, and how this can trigger disease phenotypes in the next generation. Conceived towards advanced students, medical professionals and research scientists, this is the first comprehensive textbook on this topic that will serve as a valuable reference during the years to come.

'Reprogen-ethics and the future of gender' bring together three tightly related topics, which have so far been dealt separately in bioethics: assisted reproduction, enhancing and gender. Part one in this book targets presents policies and legislature of assisted reproduction. Part two focuses on current views of the ethics of PGD and enhancing. Part three tackles the future of gender. Part four deals with artificial wombs and ectogenesis. The aim of this book is to provide a joint perspective in order to get the big picture. Contributors include John Harris, Matti Hairy, Tuija Takala, Soren Holm, David Heyd, Daniel Callahan, James Hughes, Harriet Bradley, Ekaterina Balabanova, Roy Gilbar and others. Some chapters in this book will significantly contribute to the current discussion of the topics at stake; other chapters will start a discussion on issues that have not yet been discussed. 'Reprogen-ethics and the future of gender' will certainly appeal to readers who are interested in any of the intersecting topics of assisted reproduction, genetic enhancing and gender; bioethicists, sociologists, genetic counsellors, gynaecologists, legislators, and students of the relevant disciplines.

The average age of the world's population is increasing at an unprecedented rate and this increase is changing the world. This "Silver tsunami" emphasizes the need to provide advanced training in epidemiology and increase the cadre of experts in the study of aging. This book is designed to summarize unique methodological issues relevant to the study of aging, biomarkers of aging and the biology/physiology of aging and in-depth discussions of the etiology and epidemiology of common geriatric syndromes and diseases. Contributing authors in the book represent many disciplines, not only epidemiology and clinical geriatrics, but also demography, health services, research, cardiovascular disease, diabetes, psychiatry, neurology, social services, musculoskeletal diseases and cancer. The aim of the book is to provide a broad multidisciplinary background for any student/researcher interested in aging. The material in the book is organized and comprehensive. It represents the most up-to-date information on the scientific issues in aging research written by academics who specialize in research and training in the broad field of aging. The structure and organization of the book reflects our course series in the Epidemiology of Aging starting with the broad issues of demography and methodology, and then addressing specific health conditions and geriatric conditions common to older persons.

Biogerontologists are now in a position to construct general principles of aging, and genuine attempts are being made to test and develop effective means of intervention, prevention and treatment of age-related diseases, and for achieving healthy old age. This book takes status of the molecular, cellular, hormonal, nutritional and lifestyle strategies being tested and applied. It comprises inter-dependent chapters written in the form of critical reviews by the world's leading researchers and practitioners in their respective fields. The format of the articles is a semi-academic style in which research data from various experimental systems is presented while focusing on their applications in human beings with respect to the prevention and treatment of age-related impairments.

The advent of robotic surgery brought a rise in the proportion of minimally invasive surgery in gynecology. This book provides a practical guide to this innovative field. First it introduces the basics of robotic surgery and then focuses on specific gynecology-related surgeries. Gynecologists currently practicing robotic surgery as well as those who would like to include robotic surgery in their practice will benefit greatly from this book.

Ever wondered why your life and health can sometimes be so hard to control? Or why it seems so easy for other people? Mark Hanson and Lucy Green draw on their years of experience as scientists and educators to cut through the usual information on genetics and lifestyle to reveal the secrets of early development which start to make each of us unique, during our first 1,000 days from the moment of conception. Some surprising discoveries, based on little-known new research, show how events during our first 1,000 days make each of us who we are and explain how we control our bodies, processes that go way beyond just the genes which we inherited. Provoking new ways of thinking about being parents, this book empowers individuals and society to give the next generation the gift of a good start to life and future health.

The continued debate regarding the stage at which the human embryo conceived in the laboratory should be placed in the mother, combined with recent developments in culture media formulations, have brought the role of the human blastocyst in ART back into the spotlight. ART and the Human Blastocyst presents the proceedings of the International Symposium on ART and the Human Blastocyst held from March 30- April 2, 2000 in Dana Point, California. This book brings to the forefront the main issues raised with the transfer of embryos at the blastocyst stage, including the reduction of high order multiple gestations and the role of the blastocyst culture and transfer in facilitating successful single embryo transfer. Sections include gamete quality and pregnancy outcome, physiology of the embryo, blastocyst development in culture, blastocyst transfer and fate, and implantation. More than 40 illustrations and 25 tables complement the text.

How and to what extent have Islamic legal scholars and Middle Eastern lawmakers, as well as Middle Eastern Muslim physicians and patients, grappled with the complex bioethical, legal, and social issues that are raised in the process of attempting to conceive life in the face of infertility? This path-breaking volume explores the influence of Islamic attitudes on Assisted Reproductive Technologies (ARTs) and reveals the variations in both the Islamic jurisprudence and the cultural responses to ARTs.

The over-arching goal of this volume is to help infertility practitioners evaluate and manage their patients with poor semen quality. The authors review the existing literature on the effects of medications on male fertility, and provide detailed information about what is known, giving the number of individuals and population characteristics for studies of medication effects on male fertility. Medications are designed to treat illness and reduce symptoms, but all have undesirable adverse effects such as headache or stomach upset. Some adverse reactions can even be life-threatening, so it is no surprise that some drugs have negative effects on male reproduction. Medical practitioners rarely consider a man's reproductive plans when prescribing medications. Men are routinely treated with drugs that can impair or abolish fertility. Although practitioners in the field of reproductive medicine generally realize that certain drugs impact negatively on reproductive health, there are limited resources providing evidence-based knowledge useful in counseling patients. Tables throughout this volume summarize the information for each drug, providing a handy reference for clinical use.

For counselor Nancy Wainer Cohen, this book is the sibling to "Silent Knife: Cesarean Prevention and Vaginal Birth after Cesarean "(Bergin & Garvey, 1983) her critically-acclaimed expose on America's growing reliance on cesarean sections. "Open Season "provides fresh insights and new information on the subject, offering guidance to childbearing couples, educators, health professionals, and scholars who value the natural path of childbirth.

Readers will find this book timely, informative, shocking, irreverent, and extremely readable. Cohen's intimate writing style presents a compendium of knowledge on childbirth in the fashion of a personal letter. Her aim is to lower America's alarming reliance on cesarean section, which is currently at 25 percent of all births, and to return the responsibility for childbirth to women by encouraging them to choose the kind of birthing experience they wish to have. In addition to cesarean section, Cohen discusses many other generally unnecessary interventions performed on women during pregnancy and childbirth--such as fetal monitoring and routinized hospital procedures.

The processes of aging and death remain one of the most fascinating, and mysterious, areas of biological research. Huge anomalies between species raise questions the answers to which could have fundamental implications for the field of medical science. As scientists unlock the secrets of the exceptionally long-lived little brown bat (up to 34 years), or the common budgerigar, for example, which despite having a metabolic rate 1.5 times that of a laboratory mouse, can live for up to 20 years, it has become more important than ever to be able to make a comparative analysis of the various species used in research.

Dealing with every one of the mammalian species that are employed in laboratory research, this is the first book on the subject of aging that provides detailed comparative data for age-related changes in its subjects. It does so at the level of the whole animal, its organs, organelles and molecules. The comparative data, supplied in 15 chapters by leading experts, provides information on fields as disparate as telomere function and loss, the importance of the Sirtuins and Tor, the influence of hormones on lifespans, the relationship between body size and lifespan, the effects of restricted calorific intake, age-related changes in cell replication, and DNA damage and repair. Chapters are devoted to cardiac aging, comparative skeletal muscle aging, the aging of the nervous and immune systems, the comparative biology of lyosomal function and how it is affected by age, and many other key areas of research.

This much-needed text will provide scientists working in a wide spectrum of fields with key data to aid them in their studies.

The world's population is growing at an unsustainable rate. From a baseline ?gure of one billion in 1800, global population is predicted to exceed nine billion by 2050 and 87. 8% of this growth will be localized in less developed countries. Such uneven population growth will yield a harvest of poverty, malnutrition, disease and en- ronmental degradation that will affect us all. Amongst the complex mixture of political, social, cultural and technological changes needed to address this issue, the development of improved methods of fertility regulation will be critical. The inadequacy of current contraceptive technologies is indicated by recent data s- gesting that the contraceptive needs of over 120 million couples go unmet every year. As a direct consequence of this de?cit 38% of pregnancies are unplanned and more than 50% end in an abortion, generating a total of 46 million abortions per annum particularly among teenagers. If safe, effective contraceptives were ava- able to every couple experiencing an unmet family planning need, 1. 5 million lives would be saved each year (UNFPA 2003). Progress in contraceptive technology should not only generate more effective methods of regulating fertility, but should also provide a range of methods to meet the changing needs of the world's population. Contraceptive practice was revo- tionized in 1960 in the US and 1961 in Europe by the introduction of the oral contraceptive pill by Gregory Pincus, MC Chang and colleagues, based on fun- mental hormone research conducted in Germany.

Stress is a double edged sword. Whereas chronic stress has well known harmful effects, recent research shows that intermittent exposure of cells and organisms to mild stress can improve various biological parameters, including severe stress tolerance, health span and longevity. Mild stress-induced hormesis is potentially a powerful tool in gerontological research and interventions. This book brings together some of the world leaders in this area of research who present a critical analysis of the ongoing research with respect to the effects and mechanisms of action of various types of mild stress, such as irradiation, heat, physical exercise, hypergravity, pro-oxidants and nutritional components, on a variety of biological systems ranging from fruitflies to human cells and bodies. Their separate chapters and a final collective chapter open up a whole new world of possibilities for future research in aging, successful aging, and health span extension.

Gender, Identity and Reproduction draws on a variety of perspectives relevant to an understanding of reproduction across the life-course. Through a consideration of the representation of reproductive identities and experiences, the book highlights difference and diversity in relation to contemporary reproductive choices. The book focuses on women's and men's experiences of agency, control and negotiation within the context of cultural, medical, political, theoretical and lay ideologies of the reproductive process in contemporary Western societies.

In recent years, the advancing science and increasing availability of assisted reproduction have given new hope to infertile couples. However, the use of IVF and ART has also led to marked increases in the number of multiple-infant live births. This poses a public health concern, as these neonates have a higher rate of pre-term delivery, compromising their survival chances and increasing their risk of lifelong disability. By optimizing the selection of gametes and embryos with high probabilities of implantation, it is possible to reduce the number of embryos transferred and, by extension, the number of high-risk multiple gestations, while maintaining or increasing pregnancy rates. Human Gametes and Preimplantation Embryos: Assessment and Diagnosis provides a broad yet concise overview of established and developing methodologies for assessment of gamete and embryo viability in assisted reproduction. This book elucidates the best practices for precisely selecting viable specimens based on morphology and cleavage rate and covers the spectrum of emerging adjunctive technologies for predicting reproductive potential. The authors present their extensive knowledge of "omics" approaches (genomics, transcriptomics, proteomics, and metabolomics), with unbiased delineation of the associated advantages and potential pitfalls. This valuable clinical resource is well suited to infertility specialists, Ob/Gyn physicians, IVF laboratory technicians, and researchers in the fields of embryology and reproductive medicine.

It has been over 40 years since the original report by Salmon and Daughaday demon strating that the ability of GH to stimulate sulfation of cartilage was mediated by a "sulfation factor. " In the ensuing decades, it has become apparent that this "sulfation factor activity" encompasses a complex system ofligands (IGFs), receptors, and carrier proteins that are, in tum, responsible for a wide array of cellular actions. The IGF system has been demonstrated to be critically involved in both intrauterine and postnatal growth, and to have important implications in cancer biology as well, owing to the ability of the IGFs to function in endocrine, paracrine, and autocrine modes and given the wide distri bution of IGFs in virtually every organ system. The contributions to The /GF System reflect the wide span of interest in the IGF system and its implications for normal and abnormal growth and metabolism. The chapters have been divided into four broad sections: I. Molecular biology of the IGF system; II. Bio logical actions of the IGFs; III. IGF physiology; and IV. Clinical aspects of the IGFs. We have made every effort to highlight the major contemporary themes in IGF biology, but as is inevitable in such a fast-moving field, perspectives will continue to change as new information is accumulated."

Since the late 1960s, there has been an acceleration of research focused on understanding how the efferent ducts, the epididymis, and the vas deferens function with respect to the maturation and storage of spermatozoa and as hormone dependent tissues. Another major interest in the epididymis is that it is an attractive target for the development of male contraceptives. There are well over 16,000 peer reviewed articles in the literature on these tissues, their structure, gene expression, protein synthesis and function. Regular international meetings have been initiated that are dedicated to this field. Thus, there is an urgent need for a comprehensive reference volume that spans every facet of epididymal biology, from historical background to the most current results, from basic cell and molecular biology to clinical issues. Well-established experts from every part of the world have contributed to this volume. By necessity, each author was given page limitations so that many topics are not dealt with exhaustively. Whenever possible, references to more comprehensive discussion of specific topics are included.

An analysis of cell death in reproductive physiology. It examines topics such as the control of apoptosis in the uterus during decidualization and stern cell factor regulation of apoptosis in mouse primordial germ cells.

Thanks to enormous scientific efforts of the last decades, in vitro fertilization (IVF) and in vitro production (IVP) have now been introduced successfully in the practice of human infertility treatment and cattle breeding programs. This comprehensive book allows us to bridge the knowledge from both biomedical and veterinary fields of research. For the first time, studies concerning the human embryo as well as embryos from domestic species are brought together. The central theme of the book is "the assessment of mammalian embryo quality." In 15 chapters, written by well-known scientists, different aspects of the assessment of mammalian embryo quality are summarized. Non-invasive and invasive techniques to evaluate embryo quality are separated in two parts. In addition the book is provided with appendices on practical aspects and, thus, the book should be present in each laboratory for IVF and IVP.
