A candid assessment of the pros and cons of delayed motherhood.
Biology does not bend to feminist ideals and science does not work miracles. That is the message of this eye-opening discussion of the consequences of delayed motherhood. Part personal account, part manifesto, Selvaratnam recounts her emotional journey through multiple miscarriages after the age of 37. Her doctor told her she still "had time," but Selvaratnam found little reliable and often conflicting information about a mature woman's biological ability (or inability) to conceive.
Beyond her personal story, the author speaks to women in similar situations around the country, as well as fertility doctors, adoption counselors, reproductive health professionals, celebrities, feminists, journalists, and sociologists. Through in-depth reporting and her own experience, Selvaratnam urges more widespread education and open discussion about delayed motherhood in the hope that long-lasting solutions can take effect. The result is a book full of valuable information that will enable women to make smarter choices about their reproductive futures and to strike a more realistic balance between science, society and personal goals.

The new reproductive technologies (NRTs) have given rise to new ethical questions that are widely debated. This book, the outcome of a European Union-wide collaborative process, draws on the experience and expertise of ethicists, lawyers, and clinical practitioners and focuses on some of the "burning issues" in different European countries. These include: donor insemination; surrogacy; preimplantation genetic diagnosis; embryo research; access to IVF treatment; and parental, professional and social responsibility. Familiar notions such as quality of life, parenthood, mothering, responsibility and personal identity surface at many points throughout the book and are refashioned to accommodate new questions. This book introduces and probes ethical questions and challenges in a hands-on way by working through relevant case studies with key commentaries and activities. It engages the reader directly in ethical reasoning and decision-making and provides clear explanations, insightful commentaries and informed debate on NRTs.

Statistical Analysis of Human Growth and Development is an accessible and practical guide to a wide range of basic and advanced statistical methods that are useful for studying human growth and development. Designed for nonstatisticians and statisticians new to the analysis of growth and development data, the book collects methods scattered throughout the literature and explains how to use them to solve common research problems. It also discusses how well a method addresses a specific scientific question and how to interpret and present the analytic results. Stata is used to implement the analyses, with Stata codes and macros for generating example data sets, a detrended Q-Q plot, and weighted maximum likelihood estimation of binary items available on the book's CRC Press web page. After reviewing research designs and basic statistical tools, the author discusses the use of existing tools to transform raw data into analyzable variables and back-transform them to raw data. He covers regression analysis of quantitative, binary, and censored data as well as the analysis of repeated measurements and clustered data. He also describes the development of new growth references and developmental indices, the generation of key variables based on longitudinal data, and the processes to verify the validity and reliability of measurement tools. Looking at the larger picture of research practice, the book concludes with coverage of missing values, multiplicity problems, and multivariable regression. Along with two simulated data sets, numerous examples from real experimental and observational studies illustrate the concepts and methods. Although the book focuses on examples of anthropometric measurements and changes in cognitive, social-emotional, locomotor, and other abilities, the ideas are applicable to many other physical and psychosocial phenomena, such as lung function and depressive symptoms.

Spermatogenesis involves the coordination of a number of signaling pathways, which culminate into production of sperm. Its failure results in male factor infertility, which can be due to hormonal, environmental, genetic or other unknown factors. This book includes chapters on most of the signaling pathways known to contribute to spermatogenesis. Latest research in germ cell signaling like the role of small RNAs in spermatogenesis is also discussed. This book aims to serve as a reference for both clinicians and researchers, explaining possible causes of infertility and exploring various treatment methods for management through the basic understanding of the role of molecular signaling. Key Features Discusses the signaling pathways that contribute to successful spermatogenesis Covers comprehensive information about Spermatogenesis at one place Explores the vital aspects of male fertility and infertility Explains the epigenetic regulation of germ cell development and fertility Highlights the translational opportunities in molecular signaling in testis

The book considers signaling events from the zygote embryo through to the blastocyst with relevant data from embryonic stem (ES) cells, including dialogue with the extracellular environment and with the maternal tract during the implantation process. Application of the knowledge described to improve the success of human and animal assisted conception is considered where appropriate, but the focus is largely on fundamental rather than applied cell/molecular biology, as this is the area that has historically been neglected. While the general features of metabolism during preimplantation development are well established, especially in terms of nutrient requirements, uptake and fate, remarkably little is known about early embryo signaling events, intracellular or intercellular, between individual embryos in vitro or with the female reproductive tract in vivo. This contrasts with the wealth of information on cell signaling in somatic cells and tissues, as a glance at any textbook of biochemistry illustrates. This lack of information is such that our understanding of the molecular cell biology of early embryos -- a prerequisite to defining the mechanisms which regulate development at this critical stage of the life cycle -- is seriously incomplete. This volume is the first to address this issue by describing the current state of knowledge on cell signaling during mammalian early embryo development and highlighting priority areas for research.

Embryology at a Glance is a highly illustrated and innovative introduction to key embryological concepts, with concise, memorable descriptions of major embryological developments.

It provides just the right level of detail on embryology and congenital abnormalities for all medical students and health professionals to develop a thorough understanding of human development and its implications for clinical practice.

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 book brings together the most up-to-date information about the physiology of progestogens. Addressing the bidirectional communication between hormones, fertility, tumors, and autoimmunity, it provides the basic science and clinical perspectives of progestogens which have not been previously available in one volume. In addition to estrogens, androgens, mineralocorticoids and glucocorticoids, progestogens are a major class of steroid hormone. While present in certain phases of estrous and menstrual cycles, progestogens are named for their function in maintaining pregnancy. This book is essentially practical in orientation, addressing the specific issues that confront the practitioner, and provides information to Obstetricians, Gynecologists, Reproductive endocrinologists, as well as Gynecological Oncologists and Rheumatologists. Contributions are from an international team of experts in the field, now completely updated in this new edition with new developments in primary dysmenorrhea and contraception.

Oncofertility is a specialty that bridges the disciplines of reproductive endocrinology and infertility and oncology, with the goal of expanding the reproductive options of cancer patients. Given fertility risks associated with specific cancer treatments, as well as the improved long-term survival made possible by these therapies, there has been growing interest in expanding reproductive options for cancer patients. Indeed, both cancer survivors and the medical community have acknowledged the importance of patient counseling and the pursuit of fertility preservation options prior to starting cancer treatment. Oncofertility Medical Practice: Clinical Issues and Implementation is the third in a series of timely and indispensable books on fertility preservation for cancer patients-the first one focused on advances in basic science research and the second one offered ethical, legal, and social perspectives on the theme. This book elucidates the latest practices and emerging treatments in oncofertility and provides necessary information on the successes, risks, and limitations of fertility preserving technologies. Authoritative and insightful, written by an impressive multi-disciplinary cadre of specialists, this book is a valuable up-to-date resource for all those practicing in this demanding field. "This excellent text is an invaluable resource and a "must read" for clinicians and researchers interested in Oncofertility. The editors and authors need to be congratulated for their fine work." Roger A. Lobo, MD, Professor of Obstetrics and Gynecology, Columbia University and Past President of the American Society for Reproductive Medicine

A much-needed overview of the available information now accumulating to indicate that assisted reproductive technologies are generally safe for both babies and mothers. However, the literature abounds with reports of a higher risk of obstetric and perinatal complications; regarding the long term outcomes for both women and children, the data are still scarce. The chapters summarized in this book review the current knowledge on long term safety of assisted reproduction and indicate the need for continued research to cover the lack of data in some specific patient groups and for recently developed treatments that only have a short period of follow-up.

A practical guide to how we can positively adapt to a changing world, from the internationally bestselling authors of The 100-Year Life 'The London Business School professors Andrew J. Scott and Lynda Gratton have been predicting how society must adapt for years. Now they have a post-pandemic road map for us all' Sunday Times Smart new technologies. Longer, healthier lives. Human progress has risen to great heights, but at the same time it has prompted anxiety about where we're heading. Are our jobs under threat? If we live to 100, will we ever really stop working? And how will this change the way we love, manage and learn from others? One thing is clear: advances in technology have not been matched by the necessary innovation to our social structures. In our era of unprecedented change, we haven't yet discovered new ways of living. Drawing from the fields of economics and psychology, Andrew J. Scott and Lynda Gratton offer a simple framework based on three fundamental principles (Narrate, Explore and Relate) to give you the tools to navigate the challenges ahead. The New Long Life is the essential guide to a longer, smarter, happier life.

In this book, leading academics and practitioners in the field of reproductive health address topics such as contraception, abortion, sexually transmitted infections, maternal and prenatal health, sexuality and reproductive rights by examining a number of critical issues in these areas. The authors describe new research, identify gaps and priorities in policy and practice, and illustrate innovative solutions. The book further addresses such current imperatives as understanding the social meanings of emergency contraception, measuring gender-based violence, improving reproductive health governance, strengthening health systems and services, and redressing institutional barriers. The book also assesses how reproductive health programs can be reconfigured to new challenges such as those posed by climate change, vulnerable youth in fragile states, and risks from new infertility treatments. Using a rich and varied set of cases, a broad public health and social science perspective, and novel methodological approaches, this book questions common assumptions, illustrates effective solutions and sets out research, policy, and programmatic agendas for the present and future. This is a comprehensive volume which provides a valuable resource to researchers, educators, practitioners, policymakers and students, as well as anyone studying or advocating for reproductive health.

The transnational industry surrounding assisted reproductive technology and regenerative medicine is based on the unacknowledged labour of gamete providers, surrogates and research subjects, and benefits from low labour costs in 'enabling' sectors such as logistics and transport. This finding calls for a comprehensive analysis of how the contemporary intersection of neoliberal capitalism and the life sciences - in short, the bioeconomy - capitalises on the body and its (re)productive capacities. The Reproductive Body at Work uptakes this challenge as it explores the relations between value production, labour and the body in one particular realm of the global bioeconomy: the South African bioeconomy of 'egg donation'. It highlights different forms and dimensions of unacknowledged or precarious human labour that are constitutive for the procurement, brokering and circulation of oocytes as valuable resources. The analysis illustrates that the respective organisation of value and labour renegotiate what 'the' (re)productive body can do, which status and roles it is ascribed, which cultural and economic values it signifies and how it is experienced and enacted within a matrix of intersectional power relations. A theoretically profound contribution to the interdisciplinary debate on 'New materialism', The Reproductive Body at Work will appeal to students and researchers interested in fields such as gender studies, medical anthropology, cultural studies, sociology, political economy and science and technology studies.

This important monograph summarizes a comprehensive study on the maturation of walking in normal children. Research, undertaken at one of the world's leading gait analysis centers, involved over 400 studies on a total of nearly 300 children in ten age-groups from one to seven years. Data are presented on anthropometric measurements; tests of developmental progress; time/distance parameters such as stride length and walking velocity; twelve joint angles on each side measured throughout the gait cycle; dynamic electromyography of phasic activity in seven lower-extremity muscle groups; and force measurements including vertical force, fore/aft shear, medial/lateral shear and torque. At each age, composite joint-angle graphs and time/distance parameters are brought together with film tracings of a representative child in that age group. In addition, advanced methods of statistical analysis have been applied to the joint-angle data to define prediction regions within which ninety-five percent of normal children should lie throughout the gait cycle. Finally, a 'decision tree' is presented from which a fitted age can be inferred for a subject based on non-age-specific data gathered in a motion analysis lab. Practical applications are demonstrated in a chapter devoted to two case studies.

Thoroughly examining the popular and expanding field of reproductive toxicology, this newly revised and expanded Third Edition provides the latest, cutting-edge scientific developments in this constantly evolving discipline. Reproductive Toxicologya (TM)s contributors are experienced regulatory agency and Clinical Research Organization representatives who currently utilize the new techniques discussed in the text and continue to revolutionize reproductive toxicology research.

This ground-breaking resource includes:

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.

It is not okay to call something a miracle without even trying to understand it. This is human developmental biology (human embryology, in terms of cells and molecules) for everyone curious enough to see it through, from the perspective of the business of becoming human - as individuals and as species; making new humans; how it happens (cells do it, ALL of it); and common variations of the process.It cannot be made quite simple and be kept quite true, but we will move as far toward simple as we can without losing touch with sound evidence. Variations from the "normal" version of the process, particularly malformations and twinning and chimerism, figure prominently in the story because there is no better way to learn about the usual than to study the unusual and see what differences in the endings these observable differences at the beginnings can make.In this book, when technical terminology is the only way, or the best way, to say what needs to be said, it is defined and explained - making the words a worthwhile part of what is here to be learned.This book defines its own new field. We cannot claim to understand how anything [human] works [as human], with no effort at understanding the emergence of its form and functions. Old and new unanswered questions are waiting to be dug out from under old unquestioned answers about how becoming human unfolds. We will also address some popular and weighty, but deeply empty assertions about the circumstances and mechanisms of our beginnings and our ceaseless becoming. We will find fundamental questions from 'the humanities' unanswerable except from biology. Human developmental biology is a foundational discipline within the humanities.

In the twentieth century, all developed nations began to undergo unprecedented demographic changes, as their birth rates declined, and life expectancies increased significantly --an average of thirty years in less than a century. These developments have caused major transformations in the composition of populations in these countries, especially in terms of the proportions of the various age groups. While the age groups of children and adolescents have decreased, those of elderly persons aged 65 and over, have increased.

Consistent with the situation in other developed nations, the absolute number and percentage of elderly persons in the Israeli population is increasing, while the percentage of younger persons is decreasing. Israel, however, differs from other developed countries in the pace of this demographic change, the composition of its population, and the ways it can address needs related to aging. The demographic figures in Israel indicate that not only is the proportion of elderly persons in the total population growing, but that the old population itself is rapidly aging as well.

This volume exemplifies how social science research can promote knowledge about and understanding of needs and opportunities for adaptation, and assist in evaluating the outcomes of policies and services on the personal, community and national levels, as well as suggest required changes. The variety of topics covered in this volume on age-related research, policies and practice reflects a wide range of research by Israeli scholars on social aspects of aging. Their research offers a glimpse into the knowledge base that has been built over the years on the aging process in Israel, the population of elderly people, and the national policies and network of services for the aged. Other developed countries with aging populations have much to learn from the Israeli experience.

Population growth and global health disparities for many reproductive and perinatal outcomes are but a few of the pressing issues facing public health today. Despite growing interest in the field, formal training in reproductive and perinatal epidemiology remains limited, with few available textbooks aimed at providing an overview of the field. In response to this need, faculty from the Eunice Kennedy Shriver National Institute of Child Health & Human Development (NICHD) and CIHR's Institute of Human Development, Child and Youth Health (IHDCYH) developed an intensive, competitive, Summer Institute in Reproductive and Perinatal Epidemiology. The curriculum of this Summer Institute has been developed into a textbook to provide students and researchers with a working knowledge of the substantive and methodologic issues underlying reproductive and perinatal epidemiology.
Reproductive and Perinatal Epidemiology offers a core curriculum that addresses the epidemiology of major reproductive and perinatal outcomes. From human fecundity to birth and neonatal outcomes, the subject is approached from as international a perspective as possible, and the unique methodologic issues underlying each outcome are discussed. Developed by leading researchers in collaboration with their students in response to their needs and concerns, this is the definitive textbook on the subject.

Although attitudes toward the aged and their care are inherent in any society, gerontology itself is a relatively recent field of study and practice. "Gerontology and the Construction of Old Age" applies the methods of discourse analysis and textual analysis to texts and documents in this newly evolved and eclectic fi eld. Green explores and identifies the literary methods and discursive regularities through which aging and the aged have been made into objects of study and treatment, and which together form a mode of knowledge production that will infl uence future texts in the field.

Because such formats of representation limit rational diagnoses of problems and rational courses of ameliorative action, policy implications in the fi eld of gerontology are a major interest of this study. Another interest is methodological. Within the broader constructionist approach to social reality, Green takes the position of "constitutive realism" the notion that social reality is linguistically constructed, primarily in speech and writing.

The book's two aims are to describe analytically the fi eld of gerontology. The field is important both for its growing academic presence and for its practical eff ects on discourse and policy concerning old age. It also hopes to help develop possibilities of inquiry associated with the linguistic, literary, and rhetorical turns of social science in recent years. "Gerontology and the Construction of Old Age" is a substantive investigation, at considerable theoretical depth, of gerontology itself, as well as a methodological treatise with broader implications for social science as it focuses upon the discourse of various professional fields.

Whilst assisted reproduction techniques (ART) have become increasingly successful and largely standardized, there is still only a partial understanding of what constitutes a 'true' embryo environment. Replicating the varying physiological conditions of the in-vivo environment that the embryo travels through in the in-vitro culture is still a major challenge in ART. This practical volume details how to organize and operate an IVF laboratory in order to mimic these conditions for successful embryo culture. Environments and equipment that are essential for running safe and efficient facilities such as maintaining good air quality and hygiene protocols, and utilizing an effective layout are covered in detail. Other chapters discuss the different consumables needed, optimal handling techniques and parameter monitoring systems, as well as recent advances in the area including artificial intelligence and automation. This is an indispensable guide to understanding the background science of culturing embryos, crucial to successful outcomes in ART.

Unlike other areas of medicine where statistics are meticulously kept by governments and global organizations, there are no accurate data to describe the number of the world's inhabitants who are overweight, obese, or morbidly obese. Despite this knowledge deficit, it should come as no surprise to readers that the medical community is facing an epidemic. Obesity is present in many of the developed countries and can also be observed in some urban areas of developing nations. The cause of this epidemic, simply stated, is overeating, but the overriding concern is more complex. Social factors, such as growing affluence since the 1950s, increasing reliance on pre-prepared meals, and the popularity of fast foods and sweetened drinks, have all contributed to the problem. Without doubt, the obesity epidemic has had adverse effects on both men and women, but in the case of women, some of its worse complications occur with those who are severely obese and pregnant. Obviously, this combination has been seen in the past, but it has increased so dramatically in its frequency that research has yet to catch up. Studies may discuss one or another aspect of caring for the obese pregnant patient, but until now, there has been no attempt to draw all such material together to try and present a comprehensive appraisal of the problem. Written by international experts, this practical guide draws on evidence-based material and is an invaluable resource for healthcare professionals dealing with obese pregnant women on a day-to-day basis.
