"Testosterone therapy can improve the overall health and feeling of well-being of aging men, improving sex drive, mental functions, and energy levels and reducing the risk of cardiovascular disease. Sex hormone therapy has likewise proved beneficial to menopausal and postmenopausal women. The success of such therapy combined with other recommended therapies -- proper nutrition, vitamins, and exercise, as described in this book and under the supervision of a physician -- will be of great interest to many men and women and their physicians. Recommended." -- Library Journal.
