XIIIth International Symposium on Spermatology by Lars Björndahl,John Flanagan,Rebecka Holmberg,Ulrik Kvist Pdf

These proceedings of the 2018 XIII International Symposium on Spermatology focus on comparative biology, and encourages discussion and the exchange of ideas. The aim of this Symposium was to provide a unique opportunity and bring together scientists from a wide spectrum of research fields – human, domestic animals and other mammals, vertebrates, insects, and plants. The underlying focus is on the function of the spermatozoon – a common feature for sexual reproduction, but extremely varied. By exploring the variability, a better understanding of male reproductive functions can develop. These proceedings address the mechanisms of physiology and pathophysiology, rather than diagnosis and treatment. The symposium featured keynote lectures by invited speakers, followed by presentations on specific aspects of the general topic of the session. Experimental studies are given priority over clinical studies of patient populations. The proceedings comprise both keynote speakers' texts and selected free communications. Posters were considered for publication in the proceedings, and the volume includes exhibited materials on the work of prominent spermatologists, highlighting their important past achievements in the field.

Spermatology by Gerd Ludwig,Julian Frick Pdf

The analysis of ejaculate, known as the spermiogram, is the crucial investigative technique in the andrological check-up for childlessness. Althoug other impor tant factors such as medical history, physical examination, hormone analysis and tests, biochemical, microbiological, immunological, and genetic tests, and histological and histochemical investigations must all be considered before a final assessment can be made of male fertility, the spermiogram is the guiding factor in estimating the prospects of fertility. Furthermore, the improvement in insemination techniques in recent years and the development of in vitro fertilization have enhanced the importance of the accurate analysis of sperm morphology and function. In view of the multiplicity of andrological investigative techniques listed above, urologists, gynecologists, physicians specializing in endocrinology and immunology, general practitioners, pathologists, and dermatologists are routin ely involved in semen analysis today. We hope in this book to address people working in all these different medical specialities. Having regard for the requirements of daily practice, we will intentionally restrict ourselves to the spermiogram, which we hope to present step by step by means of a large number of illustrations. A substantial part of the book is devoted to the morphological assessment of normal and pathological forms of spermatozoa and other cellular elements, in the form of generously illustrat ed atlas. Dr. Rovan has given us outstanding assistance in preparing the majori ty of photomicrographs.

The Functional Anatomy of the Spermatozoon by Björn A. Afzelius Pdf

The Functional Anatomy of the Spermatozoon is the 23rd volume of the series Wenner-Gren Center International Symposium Series, documenting the proceedings of the Second International Symposium on Comparative Spermatology, held in August 1973. This volume mainly focuses on the understanding of the early events at fertilization and the preliminaries of this biological process. This text specifically tackles the sperm at fertilization of lower animals and mammals, sperm motility and diversity, and spermatogenesis. This book concludes with discussions on capacitation and maturation of mammalian spermatozoa. This compendium will be valuable to morphologists, physiologists, immunologists, and biochemists, as well as to academicians interested in the study of functional anatomy of the spermatozoon.

Reproduction in Aquatic Animals by Manabu Yoshida,Juan F. Asturiano Pdf

This book provides an up-to-date overview of the various reproductive systems of a variety of aquatic animals, from invertebrates to fishes. While all terrestrial animals use internal fertilization, aquatic animals have diverse reproductive systems. Some are internal fertilizers with or without mating, but many perform external fertilization. Because of this diversity, the reproductive systems of aquatic animals represent excellent models for the study of adaptive evolution and the species specificity of fertilization. In addition, many aquatic animals, including fish, crustaceans, and mollusks, are important as fishery and aquaculture resources. In this book, up-and-coming researchers examine reproductive systems in representative aquatic animals, covering both the basic knowledge and late-breaking results. Reproduction in Aquatic Animals: From Basic Biology to Aquaculture Technology will be of interest to graduate and postgraduate students in biology and agricultural sciences, as well as to researchers and technicians in the fields of reproductive biology and fishery science and to non-academics.

Sperm Biology by Scott S. Pitnick,Dave J. Hosken,Tim R. Birkhead Pdf

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 by David Phillips Pdf

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.
