This book provides a resource of current understandings about various aspects of the biology of spermatogonia in mammals. Considering that covering the entire gamut of all things spermatogonia is a difficult task, specific topics were selected to provide foundational information that will be useful for seasoned researchers in the field of germ cell biology as well as investigators entering the area. Looking to the future, the editors predict that the foundational information provided in this book -- combined with the advent of new tools and budding interests in use of non-rodent mammalian models -- will produce another major advance in knowledge regarding the biology of spermatogonia over the next decade. In particular, we anticipate that the core molecular machinery driving different spermatogonial states in most, if not all, mammals will be described fully, the extrinsic signals emanating from somatic support cell populations to influence spermatogonial functions will become fully known, and the capacity to derive long-term cultures of SSCs and transplant the population to regenerate spermatogenesis and fertility will become a reality for higher order mammals.
Biology of Fertilization, Volume 2: Biology of the Sperm is the second in a three-volume series that brings together various lines of research about reproduction in general and fertilization in particular. It is devoted to spermatogenesis, sperm physiology, and the initial interactions of sperm with egg components. The book is organized into three parts. Part I on spermatogenesis and sperm physiology includes studies on the evolution of the sperm cell; regulatory mechanisms, sperm antigen differentiation, and maturation of sperm in the reproductive tracts in mammals; physicochemical mechanisms of the acrosome filament extrusion process; and enzymes associated with sperm cell function. Part II deals with chemotaxis in microorganisms: bacteria and slime molds. Part III on gamete recognition and binding includes studies on identifying, isolating, and characterizing specific sperm and egg surface components involved in sperm-egg interaction; fertilization in the alga Fucus; fertilization in insects; and the role of lysins in fertilization.
Sperm Biology represents the first analysis of the evolutionary significance of sperm phenotypes and derived sperm traits and the possible selection pressures responsible for sperm-egg coevolution. An understanding of sperm evolution is fast developing and promises to shed light on many topics from basic reproductive biology to the evolutionary process itself as well as the sperm proteome, the sperm genome and the quantitative genetics of sperm. The Editors have identified 15 topics of current interest and biological significance to cover all aspects of this bizarre, fascinating and important subject. It comprises the most comprehensive and up-to-date review of the evolution of sperm and pointers for future research, written by experts in both sperm biology and evolutionary biology. The combination of evolution and sperm is a potent mix, and this is the definitive account. The first review survey of this emerging field Written by experts from a broad array of disciplines from the physiological and biomedical to the ecological and evolutionary Sheds light on the intricacies of reproduction and the coevolution of sperm, egg and reproductive behavior

Spermiogenesis summarizes the process of sperm structure and development in a variety of organisms. It attempts to illustrate the structure of the organelles that characterize mature spermatozoa and to trace the morphogenesis of these organelles during sperm formation. This task is complicated by considerable variations in the structure of spermatozoa among different species and the lack of good morphological studies of sperm structure and spermiogenesis in many animal groups. The general morphological features of mammalian sperm structure differ in some ways from the features of insect sperm, the spermatozoa produced by insects appearing relatively more simple. When the functions and developmental regions of the organelles are considered, homologies between complex structures found in mammalian sperm and simpler insect sperm structures may be deduced even though the organelles in question are quite dissimilar in appearance. Such homologies will be stressed in an effort to present as general a picture of spermiogenesis as seems consistent with the species-specific variations that exist. This book will be a useful, stimulating reference for students of reproductive biology.
In the past thirty years, significant advances have been made in the field of reproductive biology in unlocking the molecular and biochemical events that regulate spermatogenesis in the mammalian testis. It was possible because of the unprecedented breakthroughs in molecular biology, cell biology, immunology, and biochemistry. In this book entitled, Molecular Mechanisms in Spermatogenesis, a collection of chapters has been included written by colleagues on the latest development in the field using genomic and proteomic approaches to study spermatogenesis, as well as different mechanisms and/or molecules including environmental toxicants and transcription factors that regulate and/or affect spermatogenesis. The book begins with a chapter that provides the basic concept of cellular regulation of spermatogenesis. A few chapters are also dedicated to some of the latest findings on the Sertoli cell cytoskeleton and other molecules (e.g., proteases, adhesion proteins) that regulate spermatogenesis. These chapters contain thought-provoking discussions and concepts which shall be welcomed by investigators in the field. It is obvious that many of these concepts will be updated and some may be amended in the years to come. However, they will serve as a guide and the basis for investigation by scientists in the field.
