Obtaining good quality sperm for in-vitro fertilization, ICSI, or for cryopreservation can be a major problem if a man suffers from medical conditions that preclude normal collection. Major advances in sperm retrieval and preparation techniques have been witnessed in recent years, allowing a better understanding of the contribution of the sperm to a couple's fertility. This Manual is a complete guide to sperm retrieval methods performed for men with azoospermia. Covering all the basic and advanced steps for implementation of these procedures, the Manual includes descriptions of the underlying science along with detailed, practical advice on methods, including tips for optimizing outcomes and trouble-shooting, using an evidence-based approach. This will be an invaluable resource for andrologists, urologists, embryologists, male fertility specialists, gynecologists, and other healthcare workers practising reproductive medicine. It is particularly valuable for reproductive laboratory personnel wishing to refine or develop technique and improve outcomes, and for IVF Quality Managers.

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.

This unique, case-based guide provides a thoughtful and comprehensive overview of the genetic basis of male infertility for the practicing clinician. In addition to discussing the molecular foundations of sperm production and the consequences of genetic abnormalities on various stages of sperm development, it examines the clinical aspects of acknowledged genetic disorders and their implications on male fertility. In so doing, it offers the necessary tools required by the clinician for the diagnosis and treatment of infertile men with genetic abnormalities. Moreover, it provides essential algorithms that may aid in counseling patients in the clinic.The text is arranged in four thematic sections for easy reference. The genetic foundation of male reproduction is presented in part 1, including regulation of sperm production, the structure of sperm chromatin, and spermatogenesis. The impact of genetic abnormalities on male infertility is the subject of part 2,covering sperm defects, mitochondrial function and DNA fragmentation. The clinical case material in part 3 illustrates real-world examples of genetic etiologies and the current diagnostic and therapeutic strategies for conditions such as vas asplasia, cryptorchidism, immotile cilia syndrome, sperm aneuploidy and other challenging scenarios. Casting forward, the fourth and final section presents an overview of future possibilities for management of genetic causes of male infertility, including gene editing.Fully exploring the clinical context of these genetic conditions in a practical manner that appeals to the practicing clinician, Genetics of Male Infertility is an exciting and essential text for reproductive medicine specialists, andrologists, urologists, researchers and all other clinicians treating infertile patients.

This comprehensive, multidisciplinary guide provides an up-to-date presentation of fertility preservation techniques with male cancer patients and other challenging conditions. Divided into four thematic sections, part one provides an overview of the pathophysiologic processes interrelating cancer and its treatment with infertility and discusses different methods of sperm preservation and fertility outcomes in cancer patients. Part two then explores male fertility preservation in various non-cancerous conditions, such as immunosuppressed, hypogonadal and transgender patients. The fundamental principles of cryobiology and sperm optimization are covered in part three, which also offers essential building blocks for scientists to develop a sperm banking service and implement high standards of practice. The final section describes the current practices of male fertility preservation along with its psychological impact on patients, and extends beyond to future innovative methods—tissue preservation, xenografting and artificial gametes—being researched and implemented in this field.Fertility preservation among cancer patients and survivors is an evolving practice, which involves focused research and timely collaboration of professionals from related fields. The Complete Guide to Male Fertility Preservation is unique and original in its design and will appeal to a larger audience of andrologists, reproductive endocrinologists, urologists, embryologists, and all other clinicians practicing reproductive medicine and oncology.

This unique textbook – the first of its kind – presents a thoughtful and comprehensive discussion of the significance of varicocele and its impact on male fertility. This hot topic is covered from a multitude of angles in seven thematic sections: origin and pathophysiology, clinical evaluation, medical and surgical therapy, controversies, pro and con debates, and clinical case scenarios. The scope of varicocele includes basic and transitional research, genetics, diagnostic testing with conventional and advanced molecular biology approaches, hormonal control, interventional therapy and assisted reproductive technology (ART). Repair of varicocele, which can be carried out by various methods, not only alleviates oxidative stress‐associated infertility but also prevents and protects against the progressive character of varicocele and its consequent upregulations of systemic oxidative stress. Even with the advances in the understanding of this intriguing disease and consensus on some areas such as diagnosis and pathophysiology, substantial controversy still exists, in particular concerning the benefits of treatment and to whom treatment should be offered. Additional chapters discuss, in depth, such controversies surrounding the role of varicocele in male infertility and present clinical case scenarios dealing with management of subclinical and clinical varicocele. A series of editorial comments is provided by the editors at the end of selected chapters, containing an objective and concise summary of the information from each chapter. In addition, chapters open up with key points for quick references and conclude with multiple choice questions and answers for immediate review and retention of the rich content.Generously illustrated, Varicocele and Male Infertility: A Complete Guide represents an invaluable tool for medical students in reproductive medicine as well as researchers and clinicians working in the field of infertility(e.g., urologists, gynecologists, reproductive endocrinologists, and embryologists) and is comprised of chapters written by leading and internationally recognized clinicians and scientists with expertise in varicocele, skillfully edited by leaders in the field.
