Male fertility, both resilient and fragile, is heavily affected by external factors such as the environment, drug use, and eating habits, in a similar way to a wall of stone that is constantly attacked and weathered to varying degrees. The use of cancer drugs, for instance, may increase life expectancy and cure diseases, but may also negatively affect male fertility. A variety of factors complicate male infertility, such as the intricate spermatogenesis process. The available methods for diagnosis are limited, not to mention treatment. However, some evidence showed that different reproductive physiologies may share some biological basis and thus molecular pathways, such as mTOR, which plays a role in testis physiology, Sertoli cell function, transcriptional and translational control of spermatogenesis, as well as drug and environmental exposure. Moreover, male fertility can also reflect men's overall health and the likelihood of suffering from certain diseases, suggesting that these events have common regulatory mechanisms. This Research Topic aims to identify these potential shared mechanisms, analyze and explore how environment, disease, drug use, and nutritional supplements affect male fertility, as well as reveal the seemingly chaotic but traceable phenomena. It will be crucial for the development of diagnostics, treatments, and maintenance methods needed to enhance male fertility, which is also the objective of this research topic. This Research Topic encourages Original Research, Reviews, and other accepted article types, including, but not limited to: • Analyses of the possible effects of environmental pollutants brought about by industry and human activities, such as endocrine-disrupting chemicals (EDCs), on male reproduction; • Links between men's overall health and fertility, as well as andrological effects of various illnesses, including infectious diseases, deficiencies, hereditary diseases, and physiological disorders; • Effects of medications and dietary supplements on male reproductive systems, such as those used for cancer treatment, psychiatric disorders, diabetes, etc; • The use of herbal and medicinal remedies to prevent or reverse adverse andrological effects caused by putative toxic chemicals and diseases; • Specific molecular mechanisms and signalling pathways that affect spermatogenesis, the testis, and sperm function associated with the above 4 points; • Shared molecular mechanisms underlying both the generation and remission of male infertility disease.

In this book, twenty-one researchers and clinicians review the study of the genetics of male infertility, the tools available in the laboratory and clinic, the current state of knowledge, and the future of research and translation into clinical diagnostics and treatments. New tools discussed are discussed. This book therefore serves as a guide to evidence-based clinical applications, and a preview of future possibilities.

This book provides andrologists and other practitioners with reliable, up-to-date information on all aspects of male infertility and is designed to assist in the clinical management of patients. Clear guidance is offered on classification of infertility, sperm analysis interpretation and diagnosis. The full range of types and causes of male infertility are then discussed in depth. Particular attention is devoted to poorly understood conditions such as unexplained couple infertility and idiopathic male infertility, but the roles of diverse disorders, health and lifestyle factors and environmental pollution are also fully explored. Research considered stimulating for the reader is highlighted, reflecting the fascinating and controversial nature of the field. International treatment guidelines are presented and the role of diet and dietary supplements is discussed in view of their increasing importance. Clinicians will find that the book’s straightforward approach ensures that it can be easily and rapidly consulted.

Recent advances in genomic and omics analysis have triggered a revolution affecting nearly every field of medicine, including reproductive medicine, obstetrics, gynecology, andrology, and infertility treatment. Reproductomics: The –Omics Revolution and Its Impact on Human Reproductive Medicine demonstrates how various omics technologies are already aiding fertility specialists and clinicians in characterizing patients, counseling couples towards pregnancy success, informing embryo selection, and supporting many other positive outcomes. A diverse range of chapters from international experts examine the complex relationship between genomics, transcriptomics, proteomics, and metabolomics and their role in human reproduction, identifying molecular factors of clinical significance. With this book Editors Jaime Gosálvez and José A. Horcajadas have provided researchers and clinicians with a strong foundation for a new era of personalized reproductive medicine. - Thoroughly discusses how genomics and other omics approaches aid clinicians in various areas of reproductive medicine - Identifies specific genomic and molecular factors of translational value in treating infertility and analyzing patient data - Features chapter contributions by leading international experts

To safeguard public health, the US Environmental Protection Agency (EPA) must keep abreast of new scientific information and emerging technologies so that it can apply them to regulatory decision-making. For decades the agency has dealt with questions about what animal-testing data to use to make predictions about human health hazards, how to perform dose-response extrapolations, how to identify and protect susceptible subpopulations, and how to address uncertainties. As alternatives to traditional toxicity testing have emerged, the agency has been faced with additional questions about how to incorporate data from such tests into its chemical assessments and whether such tests can replace some traditional testing methods. Endocrine active chemicals (EACs) have raised concerns that traditional toxicity-testing protocols might be inadequate to identify all potential hazards to human health because they have the ability to modulate normal hormone function, and small alterations in hormone concentrations, particularly during sensitive life stages, can have lasting and significant effects. To address concerns about potential human health effects from EACs at low doses, this report develops a strategy to evaluate the evidence for such low-dose effects.

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
