Immunological Influence On Human Fertility

Immunological Influence on Human Fertility covers the proceedings of the Workshop on Fertility in Human Reproduction, held at the Department of Biological Science, University of Newcastle, Australia on July 11 -13, 1977. The book focuses on topics on the immunological control of human and animal fertility. The selection first discusses the zona pellucida as a possible target in immunocontraception, immunological aspects of vasectomy, and the clinical significance of antibodies to spermatozoa. Topics include performance and significance of the SCMC-test, antibodies and fertility after vasovasostomy, vasectomy and the blood-testis barrier, cellular immune response, active and passive immunization, and tissue and species specificity. The book then tackles the nature of the barrier to autoimmunity in the excurrent ducts of the mammalian testis, immune activities of the male and female reproductive tracts, and isolation of spermatozoal antigens. The manuscript examines the immunological capacity of the male genital tract, clinical significance of antibodies to antigens of the reproductive tract, immunological aspects of vasectomy, and antigens of human trophoblasts. The text also takes a look at the immunological and anti-tumor effects of orchidectomy, immune infertility and approaches to treatment, natural insemination as an immune phenomenon, and modified seminal plasma antigens and subfertility. The selection is a valuable source of information for researchers wanting to study the immunological control of human and animal fertility.

This book offers comprehensive coverage of both basic and clinical aspects of immune reactions responsible for infertility. It has four sections focusing on Sperm antigens, Antisperm antibodies (ASAs), Clinical impact of ASAs, and Immune contraception, and include contributions from leading experts in these fields. This new edition of the book offers a comprehensive update that reflects the very significant advances in reproductive immunology that have been achieved over the past five years, especially related to the sperm proteome, sperm-egg binding/fusion proteins, gene knockout studies, and immunocontraception. Reproductive immunology continues to be a fast-growing discipline in which new knowledge is emerging almost every day. Immune Infertility is a model source of vital and reliable information on the latest scientific developments in the field. It will be of value for clinicians, scientists, students, residents, and fellows working in reproductive biology, obstetrics and gynecology, and urology.

Infertility is defned as the inability to conceive after having unprotected intercourse for a year. Infertility is increasing worldwide and has various causes both in the male and the female partner. Immune reactions to sperm can contribute up to 2–30% of infertility. The sperm has both autoantigenic as well as isoantigenic potential, and is thus capable of p- ducing antisperm antibodies (ASAs) and sperm-reactive T cells in both infertile men and women. Also, over 75% vasectomized men produce autoantibodies to sperm that can cause a problem in regaining fertility even after successful re-anastomosis in vasovasostomy. Early claims regarding the incidence and involvement of ASAs in involuntary human infertility were probably overemphasized because of unreliable techniques and naivety concerning the complexity of the immune response and antigenic nature of the sperm cell. These factors, the lack of well-designed and controlled experimental studies, and the dearth of effective therapeutic modalities resulted in the confusion of the occurrence and importance of ASAs in human infertility. Consequently, evaluation of infertile couples for ASAs and their possible role in infertility was not considered a signifcant proposition. The development of more accurate assays and the discovery of mucosal immunity capable of responses independent of systemic immunity have caused inclusion of sperm cells and genital tract secretions in the analysis of ASAs.

Understanding immunology is increasingly important in obstetrics and gynecology. Written primarily to meet the needs of practicing obstetricians and gynecologists, this book explores the role of immunological processes in reproduction. It presents immunologic concepts and illustrates important points with examples familiar to the clinician. The boo

Reproductive Immunology: Basic Concepts gives a holistic insight into the understanding of the complex interactions between the maternal immune system and the fetal/placental unit necessary for the success of pregnancy. This interaction is critical for the support of the human fetal semiallograft and the protection against infections. The book covers various topics such as B cells, macrophages, T cells, discussion on fetal signals and their impact on maternal reproductive cells such as endometrial cells, mast cells, and the role of fetal Hofbauer cells, the immune regulatory role of glucorticoids, and many other novel topics within the field of reproductive immunology. Edited and written by experts in the field, this book introduces the up-to-date knowledge of the role of the immune system during pregnancy and provides the necessary background to understand pregnancy complications associated with alterations in the functioning of the immune system. The book provides a complete discussion on the immunological aspects of pregnancy and serves as a great tool for research scientists, students, reproductive immunologists and OBGYNs. Shows the detailed evaluation of the knowledge related to each immune cell type in the pregnant and not pregnant uterus Evaluates each immune cell type and its function during specific reproductive events Provides the biological background for understanding the clinical aspects that will be discussed in subsequent volumes in the series

Life history theory seeks to explain the evolution of the major features of life cycles by analyzing the ecological factors that shape age-specific schedules of growth, reproduction, and survival and by investigating the trade-offs that constrain the evolution of these traits. Although life history theory has made enormous progress in explaining the diversity of life history strategies among species, it traditionally ignores the underlying proximate mechanisms. This novel book argues that many fundamental problems in life history evolution, including the nature of trade-offs, can only be fully resolved if we begin to integrate information on developmental, physiological, and genetic mechanisms into the classical life history framework. Each chapter is written by an established or up-and-coming leader in their respective field; they not only represent the state of the art but also offer fresh perspectives for future research. The text is divided into 7 sections that cover basic concepts (Part 1), the mechanisms that affect different parts of the life cycle (growth, development, and maturation; reproduction; and aging and somatic maintenance) (Parts 2-4), life history plasticity (Part 5), life history integration and trade-offs (Part 6), and concludes with a synthesis chapter written by a prominent leader in the field and an editorial postscript (Part 7).
