With the record-breaking demand for Viagra and ever-growing sales of synthetic male hormones, one thing is clear: men want to halt the symptoms of aging. Like women, men go through a type of menopause, in which they experience fatigue, loss of muscle mass, weakened bones, enlarged prostates, loss of hair, and perhaps worst of all, loss of sexual drive and function. These are natural manifestations of aging, and the authors contend that natural treatment -- rather than synthetic drugs -- will best help men retain their vitality without dangerous side effects.
