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.

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.

*** RECOMMENDED AS ONE OF THE TIMES' BEST SCIENCE BOOKS OF 2021 'With all the talk about testosterone in sex, sports and politics, we need a good explanation of the science and its implications, and this one is outstanding.' STEVEN PINKER, bestselling author of The Blank Slate 'There are whole books written about the idea that behavioural sex differences are a societal construct and how a male hormone we know influences animal behaviour somehow doesn't influence us. Hooven's book is a riposte to that silliness - and also a defence of a hormone that isn't just about aggression.' TOM WHIPPLE, THE TIMES, BEST SCIENCE BOOKS OF 2021 'Fascinating, vital, unputdownable.' JULIE BINDEL 'The definitive book on testosterone . . . A brave and significant book . . . simply fascinating and filled with extraordinary facts.' EVENING STANDARD 'Testosterone does what all superb popular science must do: it entertains as it educates.' THE WALL STREET JOURNAL Through riveting personal stories and the latest research, Harvard evolutionary biologist Carole Hooven shows how testosterone drives the behaviour of the sexes apart and how understanding the science behind this hormone is empowering for all. The biological source of masculinity has inspired fascination, investigation and controversy since antiquity. From the eunuchs in the royal courts of ancient China to the booming market for 'elixirs' of youth in nineteenth-century Europe, humans have been obsessed with identifying and manipulating what we now know as testosterone. And the trend shows no signs of slowing down. Thanks to this history and the methods of modern science, today we have a rich body of research about testosterone's effects in both men and women. The science is clear: testosterone is a major, invisible player in our relationships, sex lives, athletic abilities, childhood play, gender transitions, parenting roles, violent crime, and so much more. But there is still a lot of pushback to the idea that it does, in fact, contribute to sex differences and significantly influence behaviour. Hooven argues that acknowledging testosterone as a potent force in society doesn't reinforce stifling gender norms or patriarchal values. Testosterone and evolution work together to produce a huge variety of human behaviour, and that includes a multitude of ways to be masculine and feminine. Understanding the science sheds light on how we work and relate to one another, how we express anger and love, and how we fight bias and problematic behaviour to build a fairer society.

While menopause in women is a well-established and well documented phenomenon, the andropause in men is a relatively new concept. The terms male menopauseand andropausesuggest that this is an abrupt phenomenon related to a sudden deprivation of sex hormones. Unlike the menopause, which has a relatively sudden onset, the andropause appears to be a gradual process. It has been hypothesized that an androgen deficiency might develop with aging. Androgens and the Aging Male explores this hypothesis. The book focuses on the gradually progressive problems related to the decline in androgens that can occur with advancement of age. It examines the debate about the extent to which an age-dependent decline in androgens leads to health problems that affect or impair the quality of life, and the theory behind it. In addition, it reviews studies evaluating the effects of androgen supplementation. Androgens and the Aging Male comprehensively covers androgen function and how it changes over time.

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.

An Independent Publisher Book Awards Gold Medal Winner A Progressive Book of the Year A TechCrunch Favorite Read of the Year “Deeply researched and thoughtful.” —Nature “An extended exercise in myth busting.” —Outside “A critique of both popular and scientific understandings of the hormone, and how they have been used to explain, or even defend, inequalities of power.” —The Observer Testosterone is a familiar villain, a ready culprit for everything from stock market crashes to the overrepresentation of men in prisons. But your testosterone level doesn’t actually predict your appetite for risk, sex drive, or athletic prowess. It isn’t the biological essence of manliness—in fact, it isn’t even a male sex hormone. So what is it, and how did we come to endow it with such superhuman powers? T’s story begins when scientists first went looking for the chemical essence of masculinity. Over time, it provided a handy rationale for countless behaviors—from the boorish to the enviable. Testosterone focuses on what T does in six domains: reproduction, aggression, risk-taking, power, sports, and parenting, addressing heated debates like whether high-testosterone athletes have a natural advantage as well as disagreements over what it means to be a man or woman. “This subtle, important book forces rethinking not just about one particular hormone but about the way the scientific process is embedded in social context.” —Robert M. Sapolsky, author of Behave “A beautifully written and important book. The authors present strong and persuasive arguments that demythologize and defetishize T as a molecule containing quasi-magical properties, or as exclusively related to masculinity and males.” —Los Angeles Review of Books “Provides fruitful ground for understanding what it means to be human, not as isolated physical bodies but as dynamic social beings.” —Science

A groundbreaking book that examines all aspects of male aging through an evolutionary lens While the health of aging men has been a focus of biomedical research for years, evolutionary biology has not been part of the conversation—until now. How Men Age is the first book to explore how natural selection has shaped male aging, how evolutionary theory can inform our understanding of male health and well-being, and how older men may have contributed to the evolution of some of the very traits that make us human. In this informative and entertaining book, renowned biological anthropologist Richard Bribiescas looks at all aspects of male aging through an evolutionary lens. He describes how the challenges males faced in their evolutionary past influenced how they age today, and shows how this unique evolutionary history helps explain common aspects of male aging such as prostate disease, loss of muscle mass, changes in testosterone levels, increases in fat, erectile dysfunction, baldness, and shorter life spans than women. Bribiescas reveals how many of the physical and behavioral changes that we negatively associate with male aging may have actually facilitated the emergence of positive traits that have helped make humans so successful as a species, including parenting, long life spans, and high fertility. Popular science at its most compelling, How Men Age provides new perspectives on the aging process in men and how we became human, and also explores future challenges for human evolution—and the important role older men might play in them.

Behavioral correlates of hormones, emphasized by psychologists, have captured the attention of economists in the past years. Behavioral economists, in particular, have investigated the possible roles of hormones on economic decision making and behavior as well as social preferences and cognitive abilities. Testosterone, oxytocin, dopamine, serotonin and stress hormones are the foremost studied ones in economic contexts. Yet, the results are mixed and the relationship between hormones and economic behavior is under-investigated to this date. Hormone levels are measurable and manipulatable (e.g. activate, de-activate, block). The fact that the behavioral economics also employs experimental methodology makes it possible to observe both correlational and causal relationships between hormones and economic behavior. Since numerous environmental, social and biological factors interact with hormone fluctuations, capturing the true impacts of hormones on decisions and behavior is challenging. Manipulating hormone levels in the body is a method that is used to tackle this issue. Such studies compare observed behaviors of hormones or placebo administrated participants to determine causal relationships. This Research Topic welcomes the studies on the direct or indirect correlates of hormones on economic behavior and decision making to create new insights on the economic consequences of endocrine activity.
