Dr. Shippen uses case histories to prove that high levels of testosterone are directly related to higher levels of mental and physical functioning. Just as women have a menopause, so men experience a "male menopause", often called andropause, which can occur in over a period of 15 to 20 years, and which can take an equally devastating toll on strength, energy, and zest for life. In this book, Dr. Shippan uses case histories to show how adjusting levels of testosterone can have a positive effect on this time in a man's life .
