Sooner or later, starting from forty, each man knows various disorders: general tiredness, overweight, cardiovascular troubles, sexual problems, memory losses, irritability, and tendency to depress. Often, they put these disturbances on stress and overwork.These disorders are due to a natural phenomenon easy to diagnose: andropause disease that is the start point of sexual aging and of aging diseases. In 1992, Georges Debled MD presented this topic in Dallas.Unfortunately, generally, andropause disease is only recognized, occasionally and tardily by doctors, at its end stage called Low Testosterone in old age.But andropause disease has a commencement around forty, and sometimes before. That condition produces a pathologic fall in production of dihydrotestosterone, the strong sexual hormone produced from transformation of testosterone, and, consequently, sexual aging. With time, there is also a progressively pathologic fall in testosterone that finalize in Low Testosterone and diseases of aging.Lack of androgens induces diabetes, high cholesterol, arterial rigidity and hypertension, cardiovascular diseases, osteoarthritis, hearing and eye troubles, nervous breakdown, Parkinson's and Alzheimer's diseases. This book explains the mechanisms of sexual aging, prostate problems, and diseases of aging since their early stages; and how to prevent them with mesterolone, a safe mimetic hormone of dihydrotestosterone. This should be a priority for everyone who want to live a strong longevity beyond eighty.Ageless Man is already born. Do you want to be him?
