This is an authoritative reference on testosterone, and its role in human physiology and pathology.

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.

Even though research on testosterone is increasing, there is still much controversy regarding its physiology and clinical use. This book provides a broad overview on testosterone, from its basic features to the most recent evidence of clinical applicability. In addition, specific conditions in which testosterone play a pivotal role are discussed in detail, such as hypogonadism, misuse and abuse, puberty, cardiovascular effects and testosterone therapy. The testes are vital organs for reproduction of the human species, besides being the main source of testosterone production in men. Although not essential for survival, these singular structures represent the essence of male biological function. Testosterone is the most important testicular androgen in men. Low serum testosterone levels are associated with cardiovascular morbidity, metabolic syndrome, type 2 diabetes mellitus, atherosclerosis, osteoporosis, sarcopenia, and mortality. Also, there is increasing evidence that serum testosterone is a major biomarker status of men's health in general. Hypogonadism in a male refers to a decrease in one or both of the two major functions of the testes: sperm production or testosterone production. These abnormalities can result from disease of the testes (primary hypogonadism) or disease of the pituitary or hypothalamus (secondary hypogonadism). Currently, the clinical features of male hypogonadism are sufficiently well-recognized, the causes are well-known, and the tests of the hypothalamic-pituitary-testicular axis are accurate enough for the diagnosis in most patients. Testosterone, the focus hormone of this book, is used in different forms and routes of administration. Several authors unravel its peculiarities and assist in choosing the most suitable form in each case, as well as the possible risks of its misuse or even abuse in men and women, seeking alternatives to help patients in this situation.

Low testosterone isn't just about sexual health. It can increase your risk of metabolic syndrome and cardiovascular disease as you age. Symptoms may include obesity, Type 2 diabetes, osteoporotic fractures, generalized weakness and even facial hair loss.[3] If you're experiencing these signs, it's worth investigating your testosterone levels.

Popular culture often equates testosterone with virility, strength, and the macho male physique. Viewed by some as an "antiaging tonic," testosterone's reputation and increased use by men of all ages in the United States have outpaced the scientific evidence about its potential benefits and risks. In particular there has been growing concern about an increase in the number of middle-aged and older men using testosterone and the lack of scientific data on the effect it may have on aging males. Studies of testosterone replacement therapy in older men have generally been of short duration, involving small numbers of participants and often lacking adequate controls. Testosterone and Aging weighs the options of future research directions, examines the risks and benefits of testosterone replacement therapy, assesses the potential public health impact of such therapy in the United States, and considers ethical issues related to the conduct of clinical trials. Testosterone therapy remains an attractive option to many men even as speculation abounds regarding its potential.

Testosterone takes a historical approach to understanding testosterone. It is a comprehensive description of the functions of testosterone and its role in determining the biological, medical, psychological, behavioral and cultural features of the male sex/gender and the male/female differences.It is a unique reference that explains not only the biological aspects of the function of testosterone, but also the psychophysical aspects. Unlike most other hormones, testosterone not only regulates biological functions of the body, but its functions are also psychological. This wide spectrum of effects influences nearly all biological and behavioral features of a male, makes testosterone particularly exciting.Sex/gender issues are of great interest for a wide readership of experts within various disciplines and specialties including GP, gynecology, pediatrics, urology, andrology, and endocrinology. - Discusses groundbreaking discoveries about the function of endocrine glands and hormones from the 19th century until present - Includes information on the biology of testosterone production and its effects in men and women, including effects of high and low testosterone - Presents male contraception with its successes and failures as well as future directions and strategies in the development of novel effective male contraceptives - Discusses the correct, questionable and misuse of testosterone treatments

Written by the leading authority on hormone receptors and prostate cancer, this book reveals the surprising truth about how you can prevent and treat breast cancer, prostate cancer, and Alzheimer's with testosterone and other FDA-approved drugs.For decades, doctors have sought to combat prostate cancer under the mistaken assumption that testosterone fueled its growth. But the latest research into the nature of hormone receptors and therapies using bioidentical instead of synthetic hormones have caused a shift in thinking and new hope for treating this cancer with testosterone. Today the medical profession equates a diagnosis of Alzheimer's with a death sentence. In fact, the only thing doctors do is throw ineffective drugs at it and resign themselves to failure. For the first time, this book explains how testosterone can halt the disease and cure early-stage Alzheimer's. Similar breakthroughs for fighting breast cancer follow close on the heels of these revelations, outlining how the avoidance of synthetic progestins and the use of aromatase inhibitors are crucial tools in prevention and treatment. At the core of this book is the remarkable observation that we experience our highest hormone levels during our teen years--a time of life when there is no breast cancer, prostate cancer, or Alzheimer's. Could bringing hormones back to teen levels be the key to vibrant good health? The answer is a resounding yes. This thoroughly researched guide to the latest biomedical research is must-reading for medical professionals and anyone concerned about their health.
