In US security culture, motherhood is a site of intense contestation--both a powerful form of cultural currency and a target of unprecedented assault. Linked by an atmosphere of crisis and perceived vulnerability, motherhood and nation have become intimately entwined, dangerously positioning national security as reliant on the control of women's bodies. Drawing on feminist scholarship and critical studies of security culture, Natalie Fixmer-Oraiz explores homeland maternity by calling our attention to the ways that authorities see both non-reproductive and "overly" reproductive women's bodies as threats to social norms--and thus to security. Homeland maternity culture intensifies motherhood's requirements and works to discipline those who refuse to adhere. Analyzing the opt-out revolution, public debates over emergency contraception, and other controversies, Fixmer-Oraiz compellingly demonstrates how policing maternal bodies serves the political function of securing the nation in a time of supposed danger--with profound and troubling implications for women's lives and agency.

This revised and updated second edition provides a comprehensive account of the human male gamete. Detailed overviews of human sperm production, maturation, and function - and how these processes affect and influence fertility, infertility, and assisted reproduction - are given. A wide range of new developments including proteomics, spermatogenesis, sperm-specific WW domain-binding proteins, Ca2+ signalling, DNA packaging, epididymis are explored, whilst a new chapter presents information gained from mouse genetics, highlighting how it informs male fertility research. The impact of environmental factors during pre-pubertal and pubertal stages of life is also investigated. Featuring engaging prose with chapters organized topographically, The Sperm Cell remains an essential resource for andrologists, clinical scientists, and laboratory personnel.

Assisted Reproduction is a specialty undergoing rapid change as new technologies are introduced and new research challenges previous treatment options. This text examines a selection of controversial topics for both laboratory and clinical practice and tries to place them in perspective, so readers can understand how and why the current state of the question has come about and how future contributions to the debate should be measured. All physicians involved with the technologies concerned will learn from the expert contributions assembled here. CONTENTS: The use of ovarian markers * Use of molecular markers of endometrial receptivity * Use of GnRHa for triggering final oocyte maturation during ovarian stimulation cycles * Use of time-lapse embryo imaging in assisted reproductive technology practice * Use of cryopreservation for all embryos * Preimplantation genetic screening * The use of single embryo transfer * Use of luteal phase support * Measuring safety and efficiency in in vitro fertilization * To flush follicles during egg collection or not * Use of blastocyst culture * Use of mitochondrial donation * Controversies in recurrent implantation failure: From theory to practice * Fibroids: To remove or not? * Limitations of endometrioma surgery in in vitro fertilization: Possibilities of early disease control

Clinicians and scientists are increasingly recognising the importance of an evolutionary perspective in studying the aetiology, prevention, and treatment of human disease; the growing prominence of genetics in medicine is further adding to the interest in evolutionary medicine. In spite of this, too few medical students or residents study evolution. This book builds a compelling case for integrating evolutionary biology into undergraduate and postgraduate medical education, as well as its intrinsic value to medicine. Chapter by chapter, the authors - experts in anthropology, biology, ecology, physiology, public health, and various disciplines of medicine - present the rationale for clinically-relevant evolutionary thinking. They achieve this within the broader context of medicine but through the focused lens of maternal and child health, with an emphasis on female reproduction and the early-life biochemical, immunological, and microbial responses influenced by evolution. The tightly woven and accessible narrative illustrates how a medical education that considers evolved traits can deepen our understanding of the complexities of the human body, variability in health, susceptibility to disease, and ultimately help guide treatment, prevention, and public health policy. However, integrating evolutionary biology into medical education continues to face several roadblocks. The medical curriculum is already replete with complex subjects and a long period of training. The addition of an evolutionary perspective to this curriculum would certainly seem daunting, and many medical educators express concern over potential controversy if evolution is introduced into the curriculum of their schools. Medical education urgently needs strategies and teaching aids to lower the barriers to incorporating evolution into medical training. In summary, this call to arms makes a strong case for incorporating evolutionary thinking early in medical training to help guide the types of critical questions physicians ask, or should be asking. It will be of relevance and use to evolutionary biologists, physicians, medical students, and biomedical research scientists.

This volume explores the latest clinical and basic science advances in the field of reproductive sciences. Contributions from leading experts in the field cover a wide breadth of topics from in vitro fertilization to stem cell biology.Special focus is given to discussion of major obstacles in making clinical progress in the fields of in vitro fertilization, endometriois, uterine and ovarian transplantation, recurrent pregnancy loss, and preterm delivery. Novel evidence-based approaches to advance the field are discussed, including in vitro molecular approaches, translational studies, as well as those that may immediately be considered for use at the bedside to improve reproductive outcomes.

Are assisted reproductive technologies (ARTs) a medical issue or a matter of public policy, subject to restrictions? Francesca Scala employs the concept of boundary work to explain the protracted debates that ensued when Canada appointed a royal commission in 1989 to settle the issue. She reveals that both sides of the debate attempted to secure their position as authorities by challenging, defending, or blurring the boundaries between science and politics. This compelling account contributes to our understanding of the interaction between science and politics, the exercise of social control over science and technology, and the politics of expertise in policy making.
