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.

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

Any events that challenge the survival of living organisms may be classified as stressors. These stressors could include, for example, lack of food, increased population pressure, predatory pressure, climatic events or in the case of humans, loss of a loved one, lack of financial security or uncertainty in the future. Although most physiological systems are affected by stress, those systems that regulate reproductive physiology and behaviour are the most sensitive. All multicellular organisms show a stress related effect on reproduction, although the more complex organisms, such as mammals, have the most complex effects.

The objective of this book is to provide a comparative analysis of the mechanisms by which stress regulates reproduction exploring the evolution of stress perceiving systems from the simplest organisms to humans. Taking an integrated approach, utilising a genes-to-environment overview, the book examines the stressors that occur at all levels of organisation. These theories are used to examine and explain human and animal reproductive behaviour and physiology under stressful conditions providing a well-written, concise introduction to this important subject.

A critical analysis of white, working class North Americans' motivations and experiences when traveling to Central Europe for donor egg IVF Each year, more and more Americans travel out of the country seeking low cost medical treatments abroad, including fertility treatments such as in vitro fertilization (IVF). As the lower middle classes of the United States have been priced out of an expensive privatized "baby business," the Czech Republic has emerged as a central hub of fertility tourism, offering a plentitude of blonde-haired, blue-eyed egg donors at a fraction of the price. Fertility Holidays presents a critical analysis of white, working class North Americans' motivations and experiences when traveling to Central Europe for donor egg IVF. Within this diaspora, patients become consumers, urged on by the representation of a white Europe and an empathetic health care system, which seems nonexistent at home. As the volume traces these American fertility journeys halfway around the world, it uncovers layers of contradiction embedded in global reproductive medicine. Speier reveals the extent to which reproductive travel heightens the hope ingrained in reproductive technologies, especially when the procedures are framed as "holidays." The pitch of combining a vacation with their treatment promises couples a stress-free IVF cycle; yet, in truth, they may become tangled in fraught situations as they endure an emotionally wrought cycle of IVF in a strange place. Offering an intimate, first-hand account of North Americans' journeys to the Czech Republic for IVF, Fertility Holidays exposes reproductive travel as a form of consumption which is motivated by complex layers of desire for white babies, a European vacation, better health care, and technological success.

The story of human evolution has been told hundreds of times, each time with a focus that seems most informative of the teller. No matter how it is told the primary characters are rarely mothers and infants. Darwin argued survival, but today we know that reproduction is what evolution is all about. Centering on this, Trevathan focuses on birth, which gives the study of human evolution a crucial new dimension. Unique among mammals, humans are bipedal. The evolution of bipedalism required fundamental changes in the pelvis and resulted in a narrow birth canal. Humans are also large-brained animals, which means that birth is much more challenging for our species than for most other animals. The result of this mismatch of large head and narrow pelvis is that women are highly dependent on assistance at birth and their babies are born in an unusually undeveloped state when the brain is still small. "Human Birth" discusses how the birth process has evolved and ways in which human birth differs from birth in all other mammals. "Human Birth" is also concerned with mother-infant interaction immediately after birth. While working as a midwife trainee, Trevathan carefully documented the births of more than one hundred women and recorded maternal and infant behaviors during the first hour after birth. She suggests ways in which the interactions served not only to enhance mother-infant bonding, but also to ensure survival in the evolutionary past. With clarity and compelling logic Trevathan argues that modern birth practices often fail to meet evolved needs of women and infants and suggests changes that could lead to better birth experiences. This paperback edition includes a new introduction by the author.

A wide-ranging history of assisted reproductive technologies and their ethical implications. Finalist of the PROSE Award for Best Book in History of Science, Medicine and Technology by the Association of American Publishers Since the 1978 birth of the first IVF baby, Louise Brown, in England, more than eight million children have been born with the help of assisted reproductive technologies. From the start, they have stirred controversy and raised profound questions: Should there be limits to the lengths to which people can go to make their idea of family a reality? Who should pay for treatment? How can we ensure the ethical use of these technologies? And what can be done to address the racial and economic disparities in access to care that enable some to have children while others go without? In The Pursuit of Parenthood, historian Margaret Marsh and gynecologist Wanda Ronner seek to answer these challenging questions. Bringing their unique expertise in gender history and women's health to the subject, Marsh and Ronner examine the unprecedented means-liberating for some and deeply unsettling for others-by which families can now be created. Beginning with the early efforts to create embryos outside a woman's body and ending with such new developments as mitochondrial replacement techniques and uterus transplants, the authors assess the impact of contemporary reproductive technology in the United States. In this volume, we meet the scientists and physicians who have developed these technologies and the women and men who have used them. Along the way, the book dispels a number of fertility myths, offers policy recommendations that are intended to bring clarity and judgment to this complicated medical history, and reveals why the United States is still known as the "Wild West" of reproductive medicine.

This extensive book provides an up-to-date overview by leading international authorities, spanning the disciplines of neuroscience, psychology, ophthalmology, optometry, and paediatrics, of normal and pathological infant visual development. It covers the development of retinal receptors; infant sensitivity to detail, colour, contrast, and movement; binocularity, eye movements, and refraction, and cognitive processing. Childrens' visual deficits, including amblyopia and cataract are covered.

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.

This book looks at the major changes that have occurred in the theory and practice of speech therapy for children with developmental speech disorders. It looks at current issues and their clinical implications, but the overall aim of the book is to set clinical practice firmly in a theoretical framework. While it is therefore essentially a practical book for practitioners, it also engages in the academic investigation of the nature of the different types of developmental speech disorders and their consequences for the children. This discussion provides the framework in which to consider clinical management and specific clinical techniques.

A recurrent theme throughout each chapter is the impact of linguistics upon our understanding and management of children' s problems in learning to pronounce. There is no doubt that the linguistic revolution in speech and language pathology has produced an entirely new perspective on these disorders by identifying the phonological dimension of speech development.

Of equal importance is the expansion of knowledge about children' s language development. Much more information is now available about phonological development in terms of what the developmental changes are and when they occur. This information is valuable in assessment and diagnosis. The book also includes a number of competing theories explaining how children develop their pronunciation patterns. These theories provide the premises upon which to establish a principled theory of therapy.

To reflect these issues and their clinical implications the book is divided into three sections. The first section explores the framework within which to discuss developmental speech disorders.The second section covers three specific types of pathological conditions with which developmental speech disorders are associated. The third section examines the problems of children who have no evident major disabling condition and yet they experience severe difficulties learning to pronounce and subsequently, more often than not, learning to read and write.

The enormous increase in our knowledge and understanding of diabetes mellitus in recent years has resulted in new management strategies for greatly enhancing care in diabetic pregnancy. Clinicians responsible for the care of women with diabetes need to keep abreast of these advances. Diabetes and Pregnancy: An International Approach to Diagnosis and Management is a comprehensive, yet practical guide to the present state of knowledge regarding diabetic pregnancy. It summarizes published literature, and offers clear and valuable information on the practicalities of providing special care before, during and after pregnancy. This volume will be indispensable to all members of the health care team involved in the care of pregnant diabetic women and their babies, including obstetricians, neonatologists, diabetes physicians, specialist nurses, midwives as well as general practitioners.

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.

This book provides an overview of the role and function of regulatory RNAs that lack protein-coding potential in key reproductive tissues. This includes the role of small interfering RNAs (siRNAs), microRNAs (miRNAs), PIWI-interacting RNAs (piRNAs), small nucleolar RNAs (snoRNAs) and long non-coding RNAs (lncRNAs). Through clear, detailed and comprehensive debate, international leading experts discuss the role these novel regulators in normal development of sexual dimorphisms, including the differentiation of ovaries and testes, the genital tract including prostate, epididymis and uterus, as well as mammary glands. In addition, particular attention is paid on their role in pathophysiological processes within the reproductive tract. The power of next generation sequencing has proved to be an invaluable tool to discover new non-coding RNAs. While the identification of non-coding RNA is relatively easy, analysing their function represents still a challenge today. In this book, authors present historical and conceptual background information, highlight the ways in which non-coding RNAs function is analysed and present their vision of the future research in their key research area.

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.

The first book to take an integrative approach to the treatment of male infertility issues, this easily digestible guide uses graphics and visual aids to help explain key concepts in diagnosis, anatomy and treatment from a Western and Chinese medicine perspective. Dr Olivia Pojer, a Western medical doctor and Chinese medicine practitioner, uses a dual approach to the largely unexplored treatment of male infertility. The book covers common causes of the topic, the microbiome of the testes, and how to encourage better sperm production. It also includes chapters on nutraceuticals and laser therapy, as well as herbal formulas and acupuncture protocols to implement in clinical practice, along with Chinese medical lifestyle and nutrition. Addressing the so-called male factor in reproduction and its underrepresentation in treatment, this book provides a complete overview for acupuncturists and Chinese medicine practitioners treating male infertility issues.

A collection of objective essays reviewing the principal arguments for and against stem cell research. Among the issues considered are whether stem cell research treats embryos as "commodities," violates the rights of human embryos, or alienates women from their reproductive labor, and whether human embryos are entitled to full membership in the moral community.

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.

This book provides a comprehensive overview of the structural, nanotribological and nanomechanical properties of skin with and without cream treatment as a function of operating environment. The biophysics of skin as the outer layer covering human or animal body is discussed as a complex biological structure. Skin cream is used to improve skin health and create a smooth, soft, and flexible surface with moist perception by altering the surface roughness, friction, adhesion, elastic modulus, and surface charge of the skin surface.
