This book was released on 2012-03-17 with total page 671 pages. Available in PDF, EPUB and Kindle. Book excerpt: Studies on Men’s Health and Fertility provides a comprehensive series of up-to-the-minute reviews addressing the role of oxidative stress in the aetiology of reproductive pathologies in the male. This volume represents by far the most detailed, authoritative review of the field that has been produced to date. The text encompasses the basic science of reactive oxygen species (ROS) production by mammalian spermatozoa, the way in which these highly reactive molecules are processed by the germ line and the physiological significance of this redox activity in the generation of a functional gamete. The factors responsible for perturbing the delicate balance between physiological redox signaling on the one hand and oxidative stress on the other are also extensively reviewed and some of the first clues concerning the underlying mechanisms (age, heat, infection, cryostorage, aberrant lipid metabolism), clearly identified. From a clinical perspective there are chapters setting out the methods we should be using to diagnose oxidative stress in the male germ line, a clinical perspective on the aetiology of this condition and detailed considerations of the most suitable means of ameliorating such stress from a therapeutic point of view. Studies on Men’s Health and Fertility is intended to provide clinicians and scientists with a snap shot of the current status of this exciting, rapidly moving field. The book will be of value to clinicians interested in strategies for the management of oxidative stress in their infertility patients and scientists wishing to understand the molecular mechanisms underpinning the generation of ROS by these cells and its pathophysiological significance. It was not so long ago that the ability of spermatozoa to generate ROS was a hotly disputed topic. With the publication of this book such doubts can finally be laid to rest. There is now no doubt that these cells actively generate ROS, that oxidative stress is a major contributor to defects in male reproductive health and that the successful clinical management of this condition depends on developing a deeper understanding of the underlying molecular mechanisms. In this quest, Studies on Men’s Health and Fertility will be seen as a clear and important milestone.
Download or read book Male Reproductive Function and Semen written by T. Mann and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 507 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book A Practical Guide to Basic Laboratory Andrology written by Lars Björndahl and published by Cambridge University Press. This book was released on 2010-04-01 with total page 357 pages. Available in PDF, EPUB and Kindle. Book excerpt: This practical, extensively illustrated handbook covers the procedures that are undertaken in andrology and ART laboratories to analyse and assess male-factor infertility, and to prepare spermatozoa for use in assisted conception therapy. The content is presented as brief, authoritative overviews of the relevant biological background for each area, plus detailed, step-by-step descriptions of the relevant analytical procedures. Each technical section includes pertinent quality control considerations, as well as the optimum presentation of results. In addition to the comprehensive 'basic' semen analysis, incorporating careful analysis of sperm morphology, the handbook provides established techniques for the use of computer-aided sperm analysis and sperm functional assessment. Throughout the handbook the interpretation of laboratory results in the clinical context is highlighted, and safe laboratory practice is emphasized. It is an invaluable resource to all scientists and technicians who perform diagnostic testing for male-factor infertility.

Download or read book Molecular Signaling in Spermatogenesis and Male Infertility written by Rajender Singh and published by CRC Press. This book was released on 2019-11-06 with total page 338 pages. Available in PDF, EPUB and Kindle. Book excerpt: Spermatogenesis involves the coordination of a number of signaling pathways, which culminate into production of sperm. Its failure results in male factor infertility, which can be due to hormonal, environmental, genetic or other unknown factors. This book includes chapters on most of the signaling pathways known to contribute to spermatogenesis. Latest research in germ cell signaling like the role of small RNAs in spermatogenesis is also discussed. This book aims to serve as a reference for both clinicians and researchers, explaining possible causes of infertility and exploring various treatment methods for management through the basic understanding of the role of molecular signaling. Key Features Discusses the signaling pathways that contribute to successful spermatogenesis Covers comprehensive information about Spermatogenesis at one place Explores the vital aspects of male fertility and infertility Explains the epigenetic regulation of germ cell development and fertility Highlights the translational opportunities in molecular signaling in testis
Download or read book Sperm Competition in Humans written by Todd K. Shackelford and published by Springer. This book was released on 2010-10-29 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: In species with internal fertilization, sperm competition occurs when the sperm of two or more males simultaneously occupy the reproductive tract of a female and compete to fertilize an egg (Parker, 1970). A large body of empirical research has demonstrated that, as predicted by sperm competition theory, males and females in many species possess anatomical, behavioral, and physiological adaptations that have evolved to deal with the adaptive challenges associated with sperm competition. Moreover, in recent years, evolutionary biologists and psychologists have begun to examine the extent to which sperm competition may have been an important selective pressure during human evolution. Some research has suggested that male humans, like males of many bird, insect, and rodent species, might be able to adjust the number of sperm they inseminate according to the risk of sperm competition. Other research has examined whether such responses might be accompanied by psychological changes that motivate human males to pursue copulations when the risk of sperm competition is high. Furthermore, there is research suggesting that aspects of human penile anatomy might function to enhance success in sperm competition. Much of this work has been controversial; some of the findings have been disputed and others have been greeted with skepticism. However, the idea that some aspects of human psychology and behavior might best be understood as adaptations to sperm competition remains intriguing and, in certain cases, very persuasive.
Download or read book XIIIth International Symposium on Spermatology written by Lars Björndahl and published by Springer Nature. This book was released on 2021-07-22 with total page 370 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
