Carruthers explains the male menopause and why low testosterone activity is common in men over 40 and is often confused with the male mid-life crisis. Illustrations.

This is a controversial account of why, because of the barriers to testosterone action in the body, men can have normal levels of testosterone but still have life-, love-, and health-wrecking symptoms of testosterone deficiency which need treatment. The deficiency is increasingly being linked to common and serious medical conditions such as obesity, diabetes, heart and circulatory disorders, and even Alzheimers disease. This has clearly been shown by the authors pioneering research publications as well as those of other colleagues and researchers worldwide. However, in the majority of cases, they are often denied this because of the lack of understanding of the medical profession and other authorities regulating the treatment. This is a wake-up call to both doctors and patients alike to treat the symptoms of testosterone deficiency and related conditions with what the author argues is the most effective, safest, and economic form of preventive medicine of the twenty-first century.

In The Testosterone Factor, the first practical all-natural guide for midlife men, Dr. Shafiq Qaadri offers a groundbreaking strategy for assessing and overcoming—without hormonal supplements—the symptoms of male menopause, including depression, fatigue, explosive anger, loss of ambition, and, perhaps most widely recognized, loss of virility. He offers comprehensive worksheets to help readers quantify their symptoms and gauge their level of andropause, then arms them with specific, personalized strategies for improving their overall wellness. He also tackles that most sensitive of issues—"plumbing problems"—and discusses the pros and cons of Viagra and its cousins. By offering clear information in an upbeat tone, as well as a variety of lifestyle approaches, natural exercises, and step-by-step techniques, The Testosterone Factor helps the midlife andropausal man identify his priorities and follow a strategy that's best for him.

*** 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.
