This text presents research findings on the use and abuse of steroids in sports and exercise, and information on steroid use within professional sports and among Olympic athletes. In addition, information on drug use among international student athletes, adolescents and body builders is explored.

Anabolic steroids have traditionally been controversial in the sporting arena. Today, research indicates a dramatic increase in the use of anabolic steroids and other performance-enhancing drugs outside of competitive sports. With evidence of widespread steroid abuse among the general population, health professionals are citing the emergence of an

Drug abuse and addiction are common in clinical practice. Often they interfere with patient treatment or require an alternative approach. Drug Abuse and Addiction in Medical Illness: Causes, Consequences, and Treatment is a major contribution to the literature, a gold standard title offering a comprehensive range of topics for those who care for patients with addiction, conduct research in this area, or simply have an interest in the field. Offering state-of-the-art information for all those working with drug abusing or addicted patients, or for those interested in this topic from other research perspectives, the volume is a first of its kind book -- rich, comprehensive, yet focused, addressing the needs of the very active theoretical, basic, and clinical research in the field. Comprised of 46 chapters organized in four sections and developed by the leading international experts, Drug Abuse and Addiction in Medical Illness: Causes, Consequences, and Treatment covers virtually every core, as well as contemporary, topic on addiction, from the established theories to the most modern research and development in the field. Enhancing the educational value of the volume, every chapter includes an abstract and two boxes summarizing learning objectives and directions for future research. Drug Abuse and Addiction in Medical Illness: Causes, Consequences, and Treatment discusses the topic in a authoritative, systematic manner and is an indispensable reference for all clinicians and researchers interested in this rapidly changing field.

This volume was planned to provide a comprehensive survey of the role of the anabolic-androgenic steroids in the vital economy exclusive of the androgenic (sexual) functions. It seemed appropriate to bring together all of this information in an organized fashion in one volume at this time not only to serve as a source of information but also to indicate and suggest areas that need further exploration. The anabolic action of the steroid hormones has gone through a period of great activity in both basic and clinical research. A complete understanding of the manifold anabolic effects still remains to be elucidated and the art of clinical application is only gradually becoming apparent. This volume should be useful not only to the experienced investigator in both basic and clinical research but also for the novice. Furthermore, it should serve as a source of information for the careful use of these steroids in certain metabolic diseases. These steroids have had wide clinical application with variable results. In many instances further careful exploration is suggested. Other instances have demonstrated varying degrees of usefulness.

The book provides chapters on sex hormones and their modulation in neurodegenerative processes and pathologies, from basic molecular mechanisms, physiology, gender differences, to neuroprotection and clinical aspects for potential novel pharmacotherapy approaches. The book contains 14 chapters written by authors from various biomedical professions, from basic researchers in biology and physiology to medicine and veterinary medicine, pharmacologists, psychiatrist, etc. Chapters sum up the past and current knowledge on sex hormones, representing original new insights into their role in brain functioning, mental disorders and neurodegenerative diseases. The book is written for a broad range of audience, from biomedical students to highly profiled medical specialists and biomedical researchers, helping them to expand their knowledge on sex hormones in neurodegenerative processes and opening new questions for further investigation.

New developments in testosterone therapy are summarized here by internationally renowned experts. They review both basic and clinical knowledge in fourteen chapters. The book begins with the biochemistry of testosterone, its biosynthesis, metabolism and mechanisms of action in target organs. Three chapters deal with specific aspects of testosterone action, namely its role in spermatogenesis, its psychotropic effects and its effects on bones. Syndromes caused by androgen resistance are described in order to highlight the importance of properly functioning enzymes and receptors in the target organs. Causes and symptoms of male hypogonadism, the major indication for testosterone treatment, are described. Five chapters are devoted to the pharmacology, pharmacokinetics and clinical uses and abuses of testosterone preparations. The new transdermal testosterone application is described in detail. Side effects of testosterone treatment are reviewed. The possible role of androgens in the development of prostatic hypertrophy and carcinoma is discussed extensively since this question is of major concern to the clinician.

Experts everywhere are arguing over the effects of steroid use on individuals, sports, and society. Anabolic steroids build up muscle tissue. Most steroids used for medical purposes are synthesized in labs. These are used by doctors to treat a wide variety of diseases, such as muscle wasting, growth deficiency, asthma, skin conditions, and others. Two groups of people commonly abuse steroids: athletes who believe that building up more muscle will give them a competitive edge, and people who are concerned about their personal attractiveness, who wish to enhance their physique. Buying and using steroids without a prescription is illegal--and dangerous. Steroids have many serious effects on the body and mind. Too much of them can cause harm and permanent damage.

This case-based guide is written from the clinician's perspective, dealing with a defined male infertility problem, tracing the actual clinical pathway arriving at the diagnosis, and discussing the treatment options and the likely outcome. Rather than focusing on excessive theoretical details, each chapter presents a unique clinical vignette or scenario, the relevant aspects of which are followed throughout the entire chapter, correlating specific fertility issues with clinical findings, describing treatment options, prognoses and procedures (when indicated), and concluding with practical clinical pearls. Opening with chapters describing current diagnoses of male infertility and semen analysis, the subsequent cases presented cover a variety of relevant topics in male infertility, including anabolic steroid use, ejaculatory and erectile dysfunction, azoospermia, Klinefelter Syndrome, varicocele, cystic fibrosis and spinal cord injury. Additional chapters discuss choosing the right assisted conception technique and developing and managing a sperm bank. Practical and illustrative of a wide array of male fertility issues, The Diagnosis and Treatment of Male Infertility is a go-to resource for clinical andrologists, reproductive endocrinologists, urologists, primary care physicians and any professional working to treat the infertile male.

The first edition of this work, published in 1982, concentrated on the athlete's use of and the physician's knowledge of, anabolic steroids. This fully updated second edition discusses the continuing controversy over their use in competitive sports. An introduction of the use and abuse of anabolic steroids is followed by chapters on such topics as anabolic steroid compounds, the anabolic-to-androgen ratio, basic principles of muscle building, current anabolic steroid preparations, anabolic steroid regimes used by athletes, the enhancement of athletic performance, adverse physical effects and mental health risks, the classification of anabolic steroids as controlled substances, growth hormones and other anabolic hormones, the limits of urine drug testing, medical applications of anabolic steroids, muscle building and ergogenic supplements, and addictions.
