Testosterone is a steroid hormone from the androgen group. Testosterone is primarily secreted in the testes of males and the ovaries of females although small amounts are secreted by the adrenal glands. It is the principal male sex hormone and an anabolic steroid. In both males and females, it plays key roles in health and well-being. Examples include enhanced libido, energy, immune function, and protection against osteoporosis. On average, the adult male body produces about twenty times the amount of testosterone that an adult female's body does. This book presents new and important research in this field from around the world.

This book provides information on testosterone and other androgens, and their role in human physiology and pathology. It covers biosynthesis and mechanisms of action and reviews their effects on brain and behaviour, spermatogenesis, hair growth, bones, muscles, erythropoiesis, the cardiovascular system and lipids, erection, and the prostate. Therapeutic uses of testosterone preparations are carefully evaluated, including use in women, the aging male, and its abuse and detection in sport. The book reviews applications in male contraception, the role of 5a-reductase inhibitors and the controversial use of DHEA. For this book the editors have assembled the world leaders in testosterone research and clinical andrology and endocrinology. A special feature of the book is the fact that its 24 chapters were submitted simultaneously to insure rapid publication. This revised and significantly expanded edition will serve as the standard source of reference for many years.

Finalist for the Los Angeles Times Book Prize From the man who Oliver Sacks hailed as “one of the best scientist/writers of our time,” a collection of sharply observed, uproariously funny essays on the biology of human culture and behavior. In the tradition of Stephen Jay Gould and Oliver Sacks, Robert Sapolsky offers a sparkling and erudite collection of essays about science, the world, and our relation to both. “The Trouble with Testosterone” explores the influence of that notorious hormone on male aggression. “Curious George’s Pharmacy” reexamines recent exciting claims that wild primates know how to medicate themselves with forest plants. “Junk Food Monkeys” relates the adventures of a troop of baboons who stumble upon a tourist garbage dump. And “Circling the Blanket for God” examines the neurobiological roots underlying religious belief. Drawing on his career as an evolutionary biologist and neurobiologist, Robert Sapolsky writes about the natural world vividly and insightfully. With candor, humor, and rich observations, these essays marry cutting-edge science with humanity, illuminating the interconnectedness of the world’s inhabitants with skill and flair.

This pioneering study looks at the effects of prenatal testosterone on postnatal development and behavior. Hormonal effects on behavior have long been studied in animals; the unique contribution of this book is to suggest a connection between human fetal hormones and later behavior. It details for the first time testosterone's effect on social and language development, opening a new avenue of research for cognitive neuroscience. The authors look at samples of amniotic fluid taken during amniocentesis at 16 weeks' gestation, and relate the fetal level of testosterone (which is present in fetuses of both sexes, although in different quantities) to behavior at ages 1, 2, and 4 years. They argue that the amniotic fluid provides a window into the child's past—a chemical record of that child's time in the womb—that allows informed prediction about the child's future brain, mind, and behavior. This is not the retrospective speculation of psychoanalysis, they point out, but an opportunity to study development prospectively and trace developmental precursors and causes of later cognition. The study suggests that prenatal levels of testosterone affect a range of later behaviors in children, from the inclination to make eye contact with others to the size of the vocabulary. It also suggests that prenatal testosterone level may be related to the development of typically "masculine" and "feminine" behaviors. The study's ongoing research explores whether fetal testosterone has any link with the risk of developing autism. Connecting endocrinology and psychology, the authors propose that there is a biological component to behaviors often thought to be produced by the social environment.

Testosterone has inspired dreams—of restored youth, recharged sexual appetites, faster running, quicker thinking, bigger muscles—since it was first synthesized in 1935. This provocative book investigates the complex, bizarre, and sometimes outrageous history of synthetic testosterone and other male hormone therapies. Exploring many little-known social arenas—both inside and outside the medical world—in which these substances are becoming increasingly available and accepted, Testosterone Dreams examines the implications and dangers of their use in professional sports, in the workplace, in our sex lives, and beyond. Testosterone Dreams tells the story of testosterone's growing and sometimes concealed influence in our culture over the past 70 years. It explores such controversial topics as the invention and marketing of the male menopause, the disturbing history of hormonal and other medical treatments aimed at boosting or suppressing women's sexuality, and hormone doping in sporting events such as the Tour de France and the Olympics, and in Major League Baseball. It brings to light the hidden use of hormone doping by policemen, soldiers, and other workers in a variety of jobs. It also discusses the burgeoning steroid use in the gay community and its relation to AIDS, and takes a hard look at the pharmaceutical industry's promotional campaigns to create new markets for testosterone products. Testosterone Dreams is the first book to bring together the whole story of testosterone and to consider its social and ethical implications: Where does therapy end and performance enhancement begin? How are changing medical technologies affecting how we think about our identities as men and women and the elusive goal of "well-being"? This book will be essential reading as we move inexorably toward the wide-open, libertarian pharmacology that is now making these drug regimes available to a wider and wider clientele.

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.

We inherit mechanisms for survival from our primeval past; none so obviously as those involved in reproduction. The hormone testosterone underlies the organization of activation of masculinity: it changes the body and brain to make a male. It is involved not only in sexuality but in driving aggression, competitiveness, risk-taking - all elements that were needed for successful survival and reproduction in the past. But these ancient systems are carried forward into a modern world. The ancient world shaped the human brain, but the modern world is shaped by that brain. How does this world, with all its cultural, political, and social variations, deal with and control the primeval role of testosterone, which continues to be essential for the survival of the species? Sex, aggression, winning, losing, gangs, war: the powerful effects of testosterone are entwined with them all. These are the ingredients of human history, so testosterone has played a central role in our story. In Testosterone, Joe Herbert explains the nature of this potent hormone, how it operates in mammals in general and in humans in particular, what we know about its role in influencing various aspects of behaviour in men, and what we are beginning to understand of its role in women. From rape to gang warfare among youths, understanding the workings of testosterone is critical to enable us to manage its continuing powerful effects in modern society.

Androgen Deficiency and Testosterone Replacement: Current Controversies and Strategies explores the difficulties around the diagnosis and treatment of androgen deficiency. The text examines the available evidence concerning the diagnosis and treatment of men with low testosterone. It also examines controversies in the identification and management of these men. While the information contained within will be of use to those who specialize in androgen deficiency and sexual medicine, the scope of the book will serve as a source of basic information about testosterone replacement and as a source of reasoned analysis of the controversies surrounding testosterone replacement in the aging male. Physicians and physician extenders will be able to apply evidence management principles to the evaluation and treatment of men with testosterone deficiency; supported by the most recent practice guidelines available. The authors represent a select group of physicians with expertise in androgen deficiency and replacement. Androgen Deficiency and Testosterone Replacement: Current Controversies and Strategies will be of great value to all physicians and physician extenders who deliver health care to men of all ages.

This volume provides a brief résumé of the history of testosterone research, from the early pioneers through to the most recent advances in the field. We discover how steroid hormones were first identified and how testosterone was shown to be essential for male development. Moving forward we explore how and where testosterone is produced, and how the body controls testosterone production. We then investigate the impact testosterone has on different body systems both during their development and function, and how perturbation of testosterone action is associated with disease. We complete our story with an exploration of the emerging roles of testosterone in clinical therapy, and the future potential for manipulation of the testosterone signaling system for human health benefit.

¿Do you want to increase your testosterone without drugs or shady supplements? With this book you will learn how to increase your testosterone naturally and according to science. Backed by more than 130 scientific studies, you will find what worked for me to increase my testosterone levels, without drugs or unproven substances. From diet to exercise, lifestyle, supplements or even the amazing link between mind, behavior and testosterone. Everything in this book is proven by science (and my own experience). There is no room for new age nonsense or unproven theories, it just works. I never thought it could happen to me, but I suffered from low testosterone in my mid-thirties. It all started on the front seat of a car with a terrible hangover. Since months ago I have suffered from lack of motivation, low sexual drive and performance, poor focus and crappy mood… All the time. I did not know testosterone had to do with that, in fact, as many men, I did know almost nothing about the hormone. But I embarked on a personal quest to regain my former healthy testosterone levels. I researched every scientific study, every book, every paper… I experimented and I tested the results in myself, finally achieving success. And I can tell you, my energy levels went through the roof, my motivation returned, tackling project after project (including this book), and my sex drive and performance were back. And everything is explained in layman terms, don't worry about that.
