Most of us believe that more testosterone makes for more man. But what if this assumption is fundamentally wrong? What if the quest for authentic manhood is less determined by testosterone than we all thought?Bringing together extensive scientific research, author Robin Haring shows that testosterone is involved in virtually every aspect of life: relationships, work, health, sleep, diet, exercise, learning and sexuality. Drawing on the latest research in medicine, psychology and behavioral neuroscience, Haring not only reveals what testosterone can (and cannot) do for men, but also makes the compelling and radical argument that quality of life for men has very little to do with their testosterone levels and everything to do with their lifestyle.Presented with insight and humor, the book has a provocative and liberating message for all of us: testosterone levels are much more malleable than previously thought which means that men are not doomed to be the passive victims of age-related testosterone depletion. But above and beyond this, the book has a subversive message. It says that your testosterone level is not and ought not to be the benchmark for successful living. Each individual man has the freedom to define this for himself. Because you are more than your testosterone level. Are you ready for that?

Holding a PhD in epidemiology, Professor Robin Haring's scientific work focuses on the role of low testosterone concentrations as a cardiovascular risk factor in men. With more than 50 publications in peer-reviewed medical journals, he has made a significant contribution to establish testosterone as a men's health biomarker.
