Foreword
Drs. Parekattil (University of Florida) and Agarwal (Cleveland Clinic) have combined their expertise in the clinical and laboratory science, respectively, of male reproduction to create a novel and valuable textbook. Dr. Parekattil’s urologic fellowships at the Cleveland Clinic in both male infertility/microsurgery and laparoscopic/robotic surgery added considerably to his vision of the field of male fertility. He has pioneered the area of robotic microsurgical procedures for correction of obstructions in the male reproductive tract, varicocelectomy, neurolysis of the spermatic cord for relief from scrotal and groin pain, and for other procedures. Dr. Agarwal is a recognized authority in the study of the effect of reactive oxygen species (ROS) in the semen and their impact on sperm function. The compilation of a textbook that contains chapters that are written by so many international experts in both clinical and laboratory areas of male reproduction is a prodigious undertaking and the editors are to be congratulated for their efforts to create this book. Drs. Wiser, Sandlow, and Köhler (University of Wisconsin at Milwaukee) offer an encyclopedic discussion on a wide variety of causes of male infertility. They consider genetic, anatomic, endocrine, environmental, coital, immunologic, and surgically correctable factors that may affect a man’s fertility potential, and options for treatment other than in vitro fertilization (IVF)/ICSI of many of these conditions. Drs. Haywood, Laborde, and Brannigan (Northwestern University) offer a detailed discussion of various endocrinopathies that may cause male infertility. Drs. Agarwal and du Plessis (Tygerberg, South Africa) offer a chapter concerning the impact of obesity on male fertility. Drs. Mori and Sabanegh (Cleveland Clinic) present a detailed consideration of laboratory tests that are used for the diagnosis of male infertility. Dr. Claudio Teloken and associates (Brazil) discuss various environmental factors that may cause male infertility. The effects of various malignancies and of irradiation therapy and chemotherapy used to treat these malignancies on spermatogenesis are reviewed by Daniel Williams, IV (University of Wisconsin), who also discusses the use of sperm that were cryopreserved before treatment for assisted reproductive technologies when spermatogenesis does not resume after chemotherapy. Drs. Faasse and Niederberger (University of Illinois at Chicago) present a detailed discussion of the epidemiological considerations of male infertility, including considerations about the incidence and prevalence of infertility in developed countries and in the developing world. They consider the relationship between semen parameters and male infertility and whether or not semen parameters predict fertility and assisted reproductive technology (ART) outcomes. Their chapter also concerns novel assays for the evaluation of male infertility and whether or not male semen quality is declining, as well as health care resource utilization for male infertility in the USA. Dr. Henkel (Bellville, South Africa) gives a thorough discussion of infections of the male genitourinary tract according to the etiologic agent and the location of the infection within the genitourinary tract.

Drs. Inci and Gunay (Turkey) discuss medications and other exogenous agents that may decrease the male fertility potential. Drs. Cohen and Moseley (University of Florida) present four fascinating cases of ethical issues that may arise and create problems to both physicians and patients when making decisions about the management of fertility problems. Dr. Vaithinathan et al. (Puducherry, India) consider the various causes of apoptosis that may affect a man’s fertility status, while Drs. Misro and Ramya (New Delhi, India) offer an elegant view of fuel energy sources for spermatozoa. Drs. Hsieh and Shin (Georgetown University) discuss nutritional pathways to protect male reproductive health. Their chapter primarily concerns the use of various antioxidants for infertile men and the impact of obesity on men’s fertility potential. Dr. Pasqualotto et al. (Brazil) discuss the effect of the aging process on male fertility status and the effect of increased DNA abnormalities that occur with increasing age on the genomic pattern of the offspring of aged men. Dr. Kumar (New Delhi, India) discusses various causes of azoospermia in India, some of which are rarely, if ever, seen in the USA. He also presents his techniques for microsurgical vasoepididymostomy and for microsurgical varicocelectomy. Drs. Cassidy, Jarvi, Grober, and Lo (Toronto, Canada) discuss their use of a “mini-incision” to perform vasectomy reversal using no-scalpel techniques. Drs. Hsiao and Goldstein (Cornell Weill School of Medicine) discuss the historical development of microsurgical vasoepididymostomy. The latter author’s extensive experience with that procedure and the evolution of his anastomotic technique are described in detail. Drs. Stember and Schlegel (also at Cornell Weill) review Schlegel’s extensive experience with microsurgical dissection for testicular sperm extraction (microTESE). All aspects of dealing with patients who have non-obstructive azoospermia, including genetic findings, testicular histology and hormonal values in these patients are considered. The details of the microTESE procedure, including sperm processing methods and results, are clearly described. Various discussions of the use of robotic microsurgery are contained in this book. Drs. Brahmbhatt and Parekattil discuss robotic microsurgery to perform vasovasostomy, varicocelectomy, as well as to perform spermatic cord denervation and robotic single port neurolysis to relieve scrotal and groin pain caused by various etiologies. They describe newly available and prototype instrumentation for robotic microsurgery. Drs. Shu and Wang (Houston, Texas) discuss their method of robotic microsurgical varicocelectomy. They deliver the spermatic cord externally in the normal operative manner, but then use the DaVinci robot to perform dissection within the cord. They found a short learning curve to perform this procedure and now prefer this method for performing varicocelectomy due to the complete lack of tremor and the ease of identification of the various structures within the spermatic cord. Dr. De Wil et al. (Belgium and Switzerland) present interesting arguments that robotic vasovasostomy is useful to reduce tremor and to enhance dexterity when this procedure is performed. They also discuss the background of robotic surgery and describe the details of their method of robotic vasovasostomy. While many may question the value of robots for urologic microsurgical procedures, the total elimination of tremor when the robot is used certainly should improve the results of microsurgical procedures. The question that will need to be answered in the future is whether or not cost/benefit considerations support the use of robots for urologic microsurgery except for the unusual situation in which repair of vasal obstruction deep within the pelvis may be required. Drs. Rosevear and Wald (University of Iowa) review experimental procedures to develop vas deferens allografts to bridge the gap when the distance between the two ends of the vas is too long for reconstruction to be performed with microsurgical vasovasostomy. A chapter by Drs. Ignatov and Turek (San Francisco) concerns the diagnosis and management of various types of ejaculatory dysfunction, as well as the surgical treatment of ejaculatory duct obstruction. Drs. Cocuzza (Sao Paulo, Brazil) and Parekattil discuss the various uses of radiology in the diagnosis and treatment of male infertility. There are detailed discussions about IVF and intracytoplasmic sperm injection (ICSI) in the treatment of male infertility. Drs. Rhoton-Vlasak and Drury (University of Florida) discuss

their institution’s multidisciplinary clinic for the evaluation of couples as potential candidates for ART and describe in great detail the laboratory aspects of ARTs, including the indications for, and use of, antioxidants in vitro during ART procedures. Dr. Antinori (Italy) discusses motile sperm organellar morphology examination (MSOME) to reach a final video magnification of 6,600×. This allows the detection of subcellular abnormalities of sperm. The author assumes that certain subcellular microscopic changes in sperm are a result of exposure to reactive oxygen species. Subsequently, the intracytoplasmic morphologically selected sperm injection (IMSI) procedure is described as a new method of sperm selection to treat couples with previously failed ICSI cycles. This technology currently is so expensive that it falls into the category of experimental therapy, but it offers promise for the future. Drs. Grunewald and Paasch (Leipzig, Germany) also elaborate on subcellular and other methods of sperm selection for ICSI. The discussions about the effect of ROS on sperm quality and male fertility and on the use of antioxidants to treat male infertility are virtually encyclopedic in nature. Dr. Lampiao et al. review oxidative stress, the physiologic role of ROS in normal sperm physiology, the pathologic effects of ROS on sperm function, and the prevention of, and therapy for, impaired fertility due to seminal fluid ROS. Dr. Balercia et al. from Italy discuss the role of coenzyme Q10 and l-carnitine in the treatment of ROS damage to sperm, and Drs. Iremashvili, Brackett, and Lynne (University of Miami) discuss the sources, consequences, and possibility for therapy of ROS in the semen of spinal cord injured men. Drs. Said (Toronto, Canada) and Agarwal contribute information about the use of antioxidants in sperm cryopreservation. Dr. Lanzafame et al. (Syracuse and Catania, Italy) present detailed information about the use and value of a host of antioxidants to treat ROS-induced sperm damage. As a balance to these considerations of antioxidant therapy, the harmful effects and risks of antioxidant therapy are discussed by Drs. Stewart and Kim (University of Tennessee). Dr. Garrido et al. (Valencia, Spain) discuss the role of antioxidants in ICSI. Drs. Celik-Ozenci (Antalya, Turkey) and Huszar (Yale University) add other aspects of oxidative stress on sperm and mention the fact that medical therapy for this problem has not proved to be significantly successful. They show the benefits of the sperm–hyaluronic acid binding assay and hyaluronic acid-mediated selection of single sperm without DNA chain fragmentation in order to select sperm for ICSI. Drs. Hwang and Lamb (Baylor at Houston) offer an explanation for the molecular mechanisms of antioxidants in male infertility. Dr. Tremellen (Australia) contributes a critical review of the literature concerning the effectiveness of antioxidant therapy for the enhancement of male reproductive health. The author should be congratulated on presenting an overview of the common methodological weaknesses in antioxidant trials. Dr. Ko and others (Cleveland Clinic) conclude that there is a need for randomized controlled trials regarding the value of medical treatment of infertility due to ROS. Dr. Alvarez (Barcelona) discusses the effects on sperm function after thawing that are caused by the loss of intracellular antioxidant enzyme activity during cryopreservation. Dr. Varghese et al. (Montreal, Canada and Cleveland Clinic) discuss the use of antioxidants during embryo culture and during embryo cryopreservation to prevent lipid peroxidation of the cell membrane of the developing embryo. A unique feature of the book is the inclusion of a section of “Expert Commentary” at the end of many of the chapters. This treatise contains discussions of virtually all areas of the diagnosis and treatment of male infertility and also contains information about newer evolving therapies to treat male infertility. The chapters on ethical considerations in male infertility and on the management of chronic inguinal and scrotal pain are welcome additions that are not usually found in textbooks concerning male infertility. The addition of the various laboratory considerations of male infertility makes the book valuable for the libraries of not only clinicians, but also of laboratory scientists. Louisville, KY

Preface
The field of male infertility truly illustrates the need for a multispecialty approach to the effective diagnosis and management of such conditions. From the initial referral possibly from a reproductive endocrinology gynecologist and embryologist to the male infertility urologist, andrologist, nurses, researchers, and alternative medicine specialists, this multidisciplinary team needs to work as a cohesive unit to provide our patients with the most effective and highest quality care. This book was an attempt to gather experts from each of these fields and present an integrated management approach with detailed descriptions of topics ranging from the initial clinical diagnosis, management, new treatment options, and scientific rational for the various approaches. The book initially focuses on the clinical aspects of male infertility and then dives into the use of antioxidants as adjunctive therapy and the current state of affairs in antioxidant research. The authors come from leading institutions from around the globe in an attempt to capture a wide range of techniques and approaches. We are hoping that this text may serve as a reference guide for specialists across this team to further enhance dialogue, discussion, and refinement in our multidisciplinary approach. We would like to thank the authors for their contributions and our families for their patience in allowing us to put together this project. We would like to acknowledge the Glickman Urological Institute at the Cleveland Clinic Foundation and the Department of Urology at University of Florida for institutional support for this endeavor as well. We are grateful to Richard Lansing, executive editor, for his support and advice, and to Margaret Burns, developmental editor, for her tireless efforts in reviewing and editing each of the manuscripts. We hope that this book will provide a concise, consolidated reference for antioxidants and male infertility. Winter Haven, FL, USA Cleveland, OH, USA
