Oxidants, Antioxidants and Impact of the Oxidative Status in Male Reproduction is an essential reference for fertility practitioners and research and laboratory professionals interested in learning about the role of reactive oxygen species in sperm physiology and pathology. The book focuses on unravelling the pathophysiology of oxidative stress mediated male infertility, recruiting top researchers and clinicians to contribute chapters. This collection of expertise delves into the physico-chemical aspects of oxidative stress, including a new focus on reductive stress. Furthermore, the inclusion of clinical techniques to determine oxidative stress and the OMICS of reductive oxidative stress are also included.

This is a must-have reference in the area of oxidative stress and male reproductive function.

Offers comprehensive information on oxidative stress and its role in male reproduction, including new therapeutic approaches Deals with current approaches to oxidative stress using OMICS platform< Designed for fertility practitioners, reproductive researchers, and laboratory professionals interested in learning about the role of reactive oxygen species in sperm physiology and pathology

Herbal Medicine in Andrology: An Evidence-Based Update provides a comprehensive overview of ethnomedical approaches in andrology, including ethnopharmacology of plant extracts and relevant bioactive compounds. It highlights information on the availability of medicinal plants and the legal and procedural processes involved in developing a marketable product. This reference helps clinicians and scientists develop an understanding on how herbal medicine can be used to treat andrological patients in practice. Only a limited number of journal articles are available on this topic, making this reference a valuable source of information for a large audience, including urologists, andrologists, gynecologists, reproductive endocrinologists and basic scientists.

Provides essential evidence-based information about herbal medicine Offers an ethnopharmacological background on bioactive compounds in certain plant extracts Educates the basic scientist and clinician on the use of herbal medicines in andrology Provides an update to recent advances on herbal medicine in andrology from world experts

Selecting good-quality sperm for use in in-vitro fertilization is a key step in assisted reproduction. For many years purely morphological attributes have been used to assess suitability, but increasingly biochemical and molecular biological techniques are now identifying sperm with the best chances of producing viable and healthy embryos. Focusing on modern sperm function testing, this manual provides technical details of commonly used tests and gives an overview of the laboratory techniques used to evaluate sperm samples. Covering a variety of testing methods in detail, from manual and computer-assisted semen analysis to zona pellucida binding assays, and tests assessing sperm DNA damage such as the TUNEL assay. Describing the underlying science, practical advice for performing the tests is given, including tips for optimizing outcomes and trouble-shooting. This is an essential guide for reproductive medicine specialists, clinical andrologists, urologists and gynecologists working with sub-fertile men.

It also covers the most recent developments in the study of oxidative and reductive stress (redox stress), including the role of radical and reactive species, novel antioxidant therapies, and methods for assessing free radicals and redox stress.

This book pinpoints one of the fastest growing, complex subjects in chemistry and medical science: the dangers of oxidative stress to human beings. It provides a solid background on the chemistry behind the generation of reactive species as well as how reactive species are involved in essential physiological processes and in almost every human disease. It also covers the most recent developments in the study of oxidative and reductive stress (redox stress), including the role of radical and reactive species, novel antioxidant therapies, and methods for assessing free radicals and redox stress. The chapters present concise, yet thorough, summaries of the state-of-the-art methods and techniques that any investigator working in the oxidative/reductive stress field needs to access. The current methodologies including the development of sensors and biosensors for the detection of ROS/RNS/RHS and of biomarkers of redox stress are thoroughly discussed. This book is a useful resource for all researchers and students interested in oxidative stress, molecular biology, and chemistry. Physicians and healthcare professionals interested in understanding the molecular mechanisms underlying the redox stress-related diseases also stand to benefit from this book.
