ART treatment is vulnerable to the hazard of potential infection from many different sources: patients, samples, staff and the environment. Culture of gametes and embryos in vitro provides multiple targets for transmission of potential infection, including the developing embryo, neighbouring gametes and embryos, the couple undergoing treatment and other couples being treated during the same period. This unique situation, with multifaceted opportunities for microbial growth and transmission, makes infection and contamination control absolutely crucial in the practice of assisted reproduction, and in the laboratory in particular. Originally published in 2004, this practical book provides a basic overview of microbiology in the context of ART, providing a guide to infections in reproductive medicine. The relevant facets of the complex and vast field of microbiology are condensed and focused, highlighting information that is crucial for safe practice in both clinical and laboratory aspects of ART.

Illustrated with many case studies and including a final chapter on recommendations for researchers and practitioners, this book is written by expert authors involved in the prestigious IAHS PUB initiative. It is a key resource for academic researchers and professionals in the fields of hydrology, hydrogeology, ecology, geography, soil science, and environmental and civil engineering.

This addition to the Springer Brief in Stem Cells series focuses on aspects related to the specific mechanisms that ensure and control pluripotency and cell commitment in domestic animal species. This topic is generating rapidly-increasing interest due to the great potential for domestic animal species to be used as intermediate biomedical models, between the mouse and the human. The Brief addresses why we need large animal models for regenerative medicine. It also describes early embryo development with a careful and specific analysis of the regulatory mechanisms driving cleavage, polarization and genome activation in domestic species. How pluripotency is compartmentalized in domestic species as well as the different aspects that make the derivation of stem cells in domestic species very difficult are also addressed.

In the space of one generation major changes have begun to take place in the field of human reproduction. A rapid increase in the control of fertility and the understanding and treatment of sexual health issues have been accompanied by an emerging threat to reproductive function linked to increasing environmental pollution and dramatic changes in lifestyle. Organised around four key themes, this book provides a valuable review of some of the most important recent findings in human reproductive ecology. Major topics include the impact of the environment on reproduction, the role of physical activity and energetics in regulating reproduction, sexual maturation and ovulation assessment and demographic, health and family planning issues. Both theoretical and practical issues are covered, including the evolution and importance of the menopause and the various statistical methods by which researchers can analyse characteristics of the menstrual cycle in field studies.

"Studies on Men s Health and Fertility "provides a comprehensive series of up-to-the-minute reviews addressing the role of oxidative stress in the aetiology of reproductive pathologies in the male. This volume represents by far the most detailed, authoritative review of the field that has been produced to date. The text encompasses the basic science of reactive oxygen species (ROS) production by mammalian spermatozoa, the way in which these highly reactive molecules are processed by the germ line and the physiological significance of this redox activity in the generation of a functional gamete. The factors responsible for perturbing the delicate balance between physiological redox signaling on the one hand and oxidative stress on the other are also extensively reviewed and some of the first clues concerning the underlying mechanisms (age, heat, infection, cryostorage, aberrant lipid metabolism), clearly identified. From a clinical perspective there are chapters setting out the methods we should be using to diagnose oxidative stress in the male germ line, a clinical perspective on the aetiology of this condition and detailed considerations of the most suitable means of ameliorating such stress from a therapeutic point of view.

"Studies on Men s Health and Fertility "is intended to provide clinicians and scientists with a snap shot of the current status of this exciting, rapidly moving field. The book will be of value to clinicians interested in strategies for the management of oxidative stress in their infertility patients and scientists wishing to understand the molecular mechanisms underpinning the generation of ROS by these cells and its pathophysiological significance. It was not so long ago that the ability of spermatozoa to generate ROS was a hotly disputed topic. With the publication of this book such doubts can finally be laid to rest. There is now no doubt that these cells actively generate ROS, that oxidative stress is a major contributor to defects in male reproductive health and that the successful clinical management of this condition depends on developing a deeper understanding of the underlying molecular mechanisms. In this quest, "Studies on Men s Health and Fertility "will be seen as a clear and important milestone. "

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.

The births of more than 100 apparently normal infants at term following pregnancies initiated by in vitro fertilization and embryo transfer testifies to the successful clinical application of insights obtained from studies in reproductive biology over the last 20 years. In women, these studies have included: 1) characterization of the changes in blood hormone profiles throughout ovulatory menstrual cycles; 2) documentation of the hormonal composition of antral fluid in developing and degenerating preovulatory follicles; 3) correlation of these observations with the state of oocyte maturation and the fertilizability of the oocyte; 4) application of pharmacologic agents for perturbing the normal hormone profiles to regulate the number of preovulatory follicles developing and the time of ovulation; and 5) development of non-invasi ve methods for monitoring follicular development. Optimizing methods for maturing and fertilizing eggs, for moni toring normal development in vi tro, and for transferring and achieving implantation of embryos are continuing concerns of physicians and scientists responsible for extant programs. In addition, all serious students of reproductive biology should critically examine every facet of the processes which must concatenate to assure birth of normal infants following pregnancies achieved by these methods. However, the literature which contains the informational substrate is dispersed widely in a plethora of journals not always readily accessible. Bringing the essentials together facilitates both rapid retrieval of data and access to relevant literature.

This Brief offers a concise, handy overview of the main concepts related to Embryology, revisited through the novel concepts that are applied daily in stem cell research and cell therapy oriented investigations.It isbased on three main areas:

-The process involved in female gamete differentiation and maturation. The main aspects related to cell biology will be covered and an overview of the epigenetic regulation of gametogenesis will be presented.

-Early stages of embryo development with a careful analysis of the regulatory mechanisms driving cleavage, polarization and genome activation.

-Stem cell and gametogenesis.

The use of the oocyte as a possible source for the derivation of stem cell lines is discussed and depicted as a powerful tool to investigate oocyte potency and asymmetric imprinting. The potential biological implications are evaluated and use of stem cells to derive oocytesis presented."

Preimplantation genetic diagnosis (PGD) is a rapidly advancing field of reproductive genetics.

Most of the following chapters were presented as plenary lectures or symposium talks at the 1986 XXXth Congress of the International Union of Physiological Sciences in Vancouver, B.C. A distinguished international group of endocrinologists and physiologists have contributed up-to-date reviews of their particular fields. The early chapters are largely concerned with the brain and neuroendocrine mechanisms controlling the secretion of gonadotropin releasing hormone (GnRH) and its action on the anterior pitui- tary gland. Later chapters focus on the gonads themselves and the systemic and intrinsic hormones influencing the functional cytology of ovarian and testicular cells. Such comprehensive subjects as sex differentiation, puberty, placentation and parturition are also discussed authoritatively. According to Pfaff and Cohen and Arai et al., gonadal steroids, especially estrogen, exert multiple effects on certain hypothalamic and preoptic neurons, including growth, protein synthesis and electrical changes, which promote plasticity and facilitate synaptogenesis. The electrophysio- logy of the hypothalamic GnRH pulse generator in the rhesus monkey is reviewed more specifically by Knobil. In ovariectomized ewes, Clarke finds both positive and negative effects of estrogen on hypothalamic release of GnRH as well as on pituitary responsiveness to the peptide. Flerk6 et al.

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.

Many reproductive and developmental health problems are caused by exposure to chemicals that are widely dispersed in our environment. These problems include infertility, miscarriage, poor pregnancy outcomes, abnormal fetal development, early puberty, endometriosis, and diseases and cancers of reproductive organs. The compelling nature of the collective science has resulted in recognition of a new field of environmental reproductive health. Focusing on exposures to environmental contaminants, particularly during critical periods in development and their potential effects on all aspects of future reproductive life-course, this book provides the first comprehensive source of information bringing together the arguments that are spread out among various scientific disciplines in environmental health, clinical and public health fields. It provides a review of the science in key areas of the relationship between environmental contaminants and reproductive health outcomes, and recommendations on efforts toward prevention in clinical care and public policy.

Public attention on embryo research has never been greater. Modern reproductive medicine technology and the use of embryos to generate stem cells ensure that this will continue to be a topic of debate and research across many disciplines. This multidisciplinary book explores the concept of a 'healthy' embryo, its implications on the health of children and adults, and how perceptions of what constitutes child and adult health influence the concept of embryo 'health'. The concept of human embryo health is considered from preconception to pre-implantation genetic diagnosis to recent foetal surgical approaches. Burgeoning capacities in both genetic and reproductive science and their clinical implications have catalysed the necessity to explore the concept of a 'healthy' embryo. The authors are from five countries and 13 disciplines in the social sciences, humanities, biological sciences and medicine, ensuring that the book has a broad coverage and approach.

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

This volume provides a brief resume of the history of testosterone research, from the early pioneers through to the most recent advances in the field. We discover how steroid hormones were first identified and how testosterone was shown to be essential for male development. Moving forward we explore how and where testosterone is produced, and how the body controls testosterone production. We then investigate the impact testosterone has on different body systems both during their development and function, and how perturbation of testosterone action is associated with disease. We complete our story with an exploration of the emerging roles of testosterone in clinical therapy, and the future potential for manipulation of the testosterone signaling system for human health benefit.

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. Finally, the authors 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."

The processes that control senescence have been the subject of more then a century of serious biological research. Two institutions closely involved in this programme, the Society for the Study of Human Biology and the British Society for Research in Ageing, held a joint symposium in 1984 to consider human ageing and longevity from an interdisciplinary point of view. The resulting book has four main sections: the evolution and genetics of ageing, biological age assessment, demographic and social aspects, and the nutritional and physiological aspects of ageing and longevity. The fundamental nature of the subject will generate interest across a wide range of biological and medical disciplines.

Reproductive ageing affects both individuals and wider society, and obstetricians and gynaecologists are witness to the impact of reproductive ageing and to some of the fears and misapprehensions of the general public. This book raises awareness of societal trends and their implications. The wider importance of the subject to the whole of society is emphasized by contributions from outside the world of obstetrics and gynaecology, both within and outside medicine. The 56th RCOG Study Group brought together a range of experts to examine reproductive ageing. This book presents the findings of the Study Group, with sections covering: background to ageing and demographics basic science of reproductive ageing pregnancy: the ageing mother and medical needs the outcomes: children and mothers future fertility insurance: screening, cryopreservation or egg donors? sex beyond and after fertility fertility treatment: science and reality - the NHS and the market the future: dreams and waking up."

It is now routine to offer men the opportunity to bank sperm prior to medical treatments where there is a high risk of testicular damage. Some men also elect to bank sperm prior to vasectomy or before embarking on a high-risk activity, such as joining the armed services. This book examines the processes involved in banking sperm from sample production and storage, the subsequent treatment of the patient and the maintenance of the samples in storage, to the process of follow-up and the ultimate fate of frozen samples. Sperm Banking: Theory and Practice will be of particular interest to andrologists and embryologists involved in the running and establishment of sperm-banking services. The book will also be useful to medical and nursing professionals and counsellors involved in the diagnosis and treatment of conditions where there is a risk of infertility as a consequence of the treatment, including oncologists, hematologists and urologists.

Over the last several decades, many biologists have been intrigued with the "immunological paradox" of pregnancy, where maternal and fetal tissues peaceably coexist despite their genetic differences. With the development of new insights on the interactive components of the immune system as well as the generation of powerful new molecular and cellular tools, singular progress has been made in understanding immunological events that culminate in successful pregnancy. This volume contains the proceedings for the first US symposium on the "Immunobiology of Reproduction" held August 26 - 29, 1993 in Boston, Massachusetts. Papers address hemotopoietic cells in reproductive tissues; growth factors/cytokines in the female reproductive tract and placenta; growth factor networks in pregnancy loss and cancer; placental expression of major histocompatibility complex and associated genes; experimental models of MHC gene expression; and immunological aspects of human infertility.

This contemporary account of male fertility provides a much-needed bridge between those seeking to understand the subject from an evolutionary and biological perspective, and those with clinical responsibility for the investigation and treatment of male infertility. Accordingly, the first half of the book deals with evolutionary aspects of male reproduction and sperm competition, sperm production and delivery in man and other animals, spermatogenesis and epididymal function, sperm transport in the female tract, and the apparent decline in human sperm count. The second part of the book puts greater emphasis on clinical problems and opens with a discussion of ICSI, including its value and limitations. This is followed by a review of modern developments in the genetics of male infertility and proceeds to a further chapter on the role of surgical procedures in the treatment of male infertility. The contributors provide a critical review of semen analysis and a full description of the molecular techniques now being used in preimplantation diagnosis and in the study of mitochondrial inheritance. This volume, written by an international team of authors, illustrates the breadth of vision needed to tackle the problem of male infertility.
