The Virility Factor: Masculinity Through Testosterone, the Male Hormone

An estimated TWELVE MILLION MEN suffer testosterone deficiency. Others fall victim to excess production. Yet, THE VIRILITY FACTOR is the ONLY book for laymen devoted to testosterone & its effects on the body, personality & sexuality. LIBRARY JOURNAL named THE VIRILITY FACTOR one of the 100 best science books of the year. PENTHOUSE FORUM: "Even as he lucidly unveils the complexities of testosterone, Bahr slips in interesting sidelines, such as information on men's annual sex cycle & exact instructions on how to measure your penis. A good book." PUBLISHERS WEEKLY: "Bahr's informed & lucid book is a boon to the man who is troubled by the most common 'masculine' problems...how a man's sexual drive, general health, appearance & psychology suffer when testosterone levels for whatever reason (stress is one) fall below the norm." Every man—& woman—should know how the relationship between testosterone & body hair, muscle building, voice pitch & strength, passive & aggressive personality traits, prostrate cancer, bone strength, symptoms of aging—virtually every aspect of life. Women too, produce testosterone, & can suffer from excesses & deficiences.
