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.

In this book the authors present current research in the study of spermatozoa. This compilation focuses on the biology, motility and function and chromosomal abnormalities of spermatozoa. Topics discussed are the epigenetic mechanisms in mammalian male germline; biological characteristics of sperm in two oyster species; sub-cellular dynamics occurring during capacitation of mammalian spermatozoa; new perspectives on the study of prion and prion-like proteins; meiotic segregation studies in spermatozoa of males carrying a structural chromosome abnormality; testicular germ cell apoptosis during orchitis; the influence of leukocytospermia on semen parameters; and spermatozoa motility and morphology.

Originally published in 2006, this is a comprehensive and definitive account of the human male gamete. The volume summarizes many unique and revealing characteristics of the sperm cell. It provides a detailed overview of human sperm production, maturation and function, and looks at how these processes affect and influence fertility, infertility and ART. The volume thus provides a detailed review of the most important research and developments, augmented with pertinent references. This book will appeal to all practitioners and scientists in reproductive medicine and in particular to clinical scientists, graduate and post-graduate scientists, and laboratory personnel.

Mammalian spermatozoa have complex structures. The structure-function relationship of sperm has been studied from various viewpoints. Accumulated evidence has shown that the sperm components undergo sequential changes from the beginning of spermatogenesis to the time of fertilization/embryogenesis. Structural analyses have been performed using various new techniques of light and electron microscopy as well as immunohistochemistry and immunocytochemistry in combination with specific probes such as antibodies against sperm components. Recently developed gene-manipulation techniques have accelerated investigations on the events that govern the relationship between the structure and molecular components of sperm. In addition, animal models with gene manipulations have been shown to exhibit various morphological and functional abnormalities that lead to infertility. In this book, I discuss the events that occur in the normal sperm head and govern the structure-function relationship from the time of spermatogenesis to that of fertilization or egg activation. In this regard, I describe dynamic modifications and maturation events occurring in sperm-head components and compare the outcomes of these events with the outcomes of their failure.
