| anatomy of a sperm: Dynamics of the Mammalian Sperm Head Kiyotaka Toshimori, 2009-05-08 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. |
| anatomy of a sperm: Sperm Competition in Humans Nicholas Pound, 2006 This volume presents the intricate ways in which sperm compete to fertilize eggs and how this has prompted reinterpretations of breeding behavior from a biological perspective.

| anatomy of a sperm: Infertility in the Male Larry I. Lipshultz, Stuart S. Howards, Craig S. Niederberger, 2009-09-24 The new edition of this canonical text on male reproductive medicine will cement the book's market-leading position. Practitioners across many specialties - including urologists, gynecologists, reproductive endocrinologists, medical endocrinologists and many in internal medicine and family practice – will see men with suboptimal fertility and reproductive problems. The book provides an excellent source of timely, well-considered information for those training in this young and rapidly evolving field. While several recent books provide targeted 'cookbooks' for those in a male reproductive laboratory, or quick reference for practising generalists, the modern, comprehensive reference providing both a background for male reproductive medicine as well as clinical practice information based on that foundation has been lacking until now. The book has been extensively revised with a particular focus on modern molecular medicine. Appropriate therapeutic interventions are highlighted throughout. |

| anatomy of a sperm: Male Reproductive Function and Semen T. Mann, C. Lutwak-Mann, 2012-12-06 To present a coherent and meaningful survey of scientific research endeavour in an area that has expanded as fast as physiology and biochemistry of reproduction in the male is no mean task these days. No less prodigious than the growth of knowledge of male reproductive function has been the rate at which the outpouring of publications on this subject has continued since the appearance of 'The Biochemistry of Semen and of the Male Reproductive Tract' in 1964. Since cyclopaedic treatment of this vast literature did not appeal to us, we have made no attempt either to rehash the material contained in that book or to enlarge the bibliography beyond the nearly 3500 references included in the present treatise. At the same time, whilst writing, we felt strongly that to advance, it is necessary to understand the past, and for this reason we have not hesitated to refer (especially in the introductory chapter) to a number of those fundamental early discoveries in which today's knowledge is deeply and firmly rooted. |
| anatomy of a sperm: Male Reproductive Anatomy Wei Wu, 2022-01-19 The male reproductive system, which is made up of the testes, scrotum, epididymis, vas deferens, seminal vesicles, prostate gland, bulbourethral gland, ejaculatory duct, urethra, and penis, functions mainly in the production, nourishment, and temporary storage of spermatozoa. Epigenetic modifications are essential to regulate normal gonadal development and spermatogenesis. The sperm epigenome is highly susceptible influence by a wide spectrum of environmental stimuli. This book focuses on the male reproductive system, discussing topics ranging from aspects of anatomy and risk factors for male infertility to clinical techniques and management of male reproductive health. |

| anatomy of a sperm: The Melancholy of Anatomy Shelley Jackson, 2010-12-01 Amusing, touching, and unsettling, The Melancholy of Anatomy is that most wonderful of fictions, one that makes us see the world in an entirely new light. Here is the body turned inside out, its members set free, its humors released upon the world. Hearts bigger than planets devour light and warp the space around them; the city of London has a menstrual flow that gushes through its underground pipes; gobs of phlegm cement friendships and sexual relationships; and a floating fetus larger than a human becomes the new town pastor. In this debut story collection, Shelley Jackson rewrites our private passages, and translates the dumb show of the body into prose as gorgeous as it is unhygienic. |
| anatomy of a sperm: Compendium of Histology Anders Rehfeld, Malin Nylander, Kirstine Karnov, 2017-09-07 This book has been designed to help medical students succeed with their histology classes, while using less time on studying the curriculum. The book can both be used on its own or as a supplement to the classical full-curriculum textbooks normally used by the students for their histology classes. Covering the same curriculum as the classical textbooks, from basic tissue histology to the histology of specific organs, this book is formatted and organized in a much simpler and intuitive way. Almost all text is formatted in bullets or put into structured tables. This makes it quick and easy to digest, helping the student get a good overview of the curriculum. It is easy to locate specific information in the text, such as the size of cellular structures etc. Additionally, each chapter includes simplified illustrations of various histological features. The aim of the book is to be used to quickly brush up on the curriculum, e.g. before a class or an exam. Additionally, the book includes guides to distinguish between the different histological tissues and organs that can be presented to students microscopically, e.g. during a histology spot test. This guide lists the specific characteristics of the different histological specimens and also describes how to distinguish a specimen from other similar specimens. For each histological specimen, a simplified drawing and a photomicrograph of the specimen, is presented to help the student recognize the important characteristics in the microscope. Lastly, the book contains multiple “memo boxes” in which parts of the curriculum are presented as easy-to-remember mnemonics. |
| anatomy of a sperm: Ultrastructure of Reproduction Jonathan van Blerkom, P. Motta, 2012-12-06 Advances in the development and application of electron microscopic techniques have occurred recently such that the electron microscope has evolved to become an essential tool in both basic and clinical research. Use of this instrument has contributed significantly to the formation of new perspectives and concepts concerning cell fine structure. These structural perspectives are now being integrated with specific functional, biochemical and pathophysiological events and processes of cells and tissues. Most recently, utilization of innovative electron microscopic techniques such as freeze-fracture, freeze etching, and scanning and high-voltage electron microscopy offers both the basic and clinical scientist potentially fundamental insights into many morphodynamic processes related to the activities of cells and tissues. Such an approach has been especially rewarding when applied to the dynamic events of gametogenesis and early embryonic development. The chapters comprising this book have been selected and edited with the aim of providing an up-to-date and comprehensive account of the most important aspects of vertebrate gamets and embryos as revealed by the integration of several different submicroscopic methods. The organization of the chapters is designed to indicate present gaps in our knowledge of the developmental and reproductive biology of gametes and the developing embryo and possible Iines of research which may lead to a lessening of these gaps. |

| anatomy of a sperm: Sperm Whales Hal Whitehead, 2003-08-15 Famed in story as the great leviathans, sperm whales are truly creatures of extremes. Giants among all whales, they also have the largest brains of any creature on Earth. Males can reach a length of sixty-two feet and can weigh upwards of fifty tons. With this book, Hal Whitehead gives us a clearer picture of the ecology and social life of sperm whales than we have ever had before. Based on almost two decades of field research, Whitehead describes their biology, behavior, and habitat; how they organize their societies; and how their complex lifestyles may have evolved in this unique environment. Among the many fascinating topics he explores is the crucial role that culture plays in the life of the sperm whale, and he traces the consequences of this argument for both evolution and conservation. Finally, drawing on these findings, Whitehead builds a general model of how the ocean environment influences social behavior and cultural evolution among mammals as well as other animals. The definitive portrait of a provocative creature, Sperm Whales will interest animal behaviorists, conservationists, ecologists, and evolutionary biologists as well as marine mammalogists. |

| anatomy of a sperm: Male Reproductive System Akmal El-Mazny, 2016-01-01 The male reproductive system consists of the hypothalamic-pituitary unit, the testes, the reproductive tract, and the external genitalia. The functions of the male reproductive system are to produce and deliver spermatozoa, for sexual reproduction, and produce hormones that regulate reproductive function and secondary sex characteristics. Abnormalities in anatomic or physiologic function affect the development and delivery of spermatozoa, and potential fertility. Male factors are often the cause of a couple's failure to conceive, therefore, it is important to evaluate and treat the male partner. A male factor may be due to abnormalities of hormonal control, testicular function, or sperm transport or delivery. This book provides a comprehensive review of the clinical anatomy and physiology specific to male reproductive system, emphasizing causes and management of male infertility. By developing a clear understanding of what is normal, you will better understand abnormalities affecting male fertility and the mechanisms behind treatment. |
| anatomy of a sperm: Sperm Counts Lisa Jean Moore, 2008-10-01 2007 Choice Outstanding Academic Title Winner of the Passing the Torch Award from the Center for Lesbian and Gay Studies It has been called sperm, semen, seed, cum, jizz, spunk, gentlemen's relish, and splooge. But however the “tacky, opaque liquid that comes out of the penis” is described, the very act of defining “sperm” and “semen” depends on your point of view. For Lisa Jean Moore, how sperm comes to be known is based on who defines it (a scientist vs. a defense witness, for example), under what social circumstances it is found (a doctor’s office vs. a crime scene), and for what purposes it will be used (in vitro fertilization vs. DNA analysis). Examining semen historically, medically, and culturally, Sperm Counts is a penetrating exploration of its meaning and power. Using a “;follow that sperm” approach, Moore shows how representations of sperm and semen are always in flux, tracing their twisting journeys from male reproductive glands to headline news stories and presidential impeachment trials. Much like the fluid of semen itself can leak onto fabrics and into bodies, its meanings seep into our consciousness over time. Moore’s analytic lens yields intriguing observations of how sperm is “spent” and “reabsorbed” as it spurts, swims, and careens through penises, vaginas, test tubes, labs, families, cultures, and politics. Drawn from fifteen years of research, Sperm Counts examines historical and scientific documents, children's “facts of life” books, pornography, the Internet, forensic transcripts and sex worker narratives to explain how semen got so complicated. Among other things, understanding how we produce, represent, deploy and institutionalize semen-biomedically, socially and culturally-provides valuable new perspectives on the changing social position of men and the evolving meanings of masculinity. Ultimately, as Moore reveals, sperm is intimately involved in not only the physical reproduction of males and females, but in how we come to understand ourselves as men and women. |
