When I first began writing Male Menopause over five years ago, very few people were aware that men, like women, experience physiological changes that affect all aspects of their lives. My goal in the book was to show that male menopause is a multidimensional life transition and can only be treated effectively by focusing on the physical, hormonal, psychological, social, spiritual, and sexual changes that occur in all men's lives, generally between the ages of forty and fifty-five.

This book draws on the latest information from my own clinical experience over the last thirty-five years, as well as from worldwide studies on sexuality, longevity, and vitality medicine. In late 1997, this book was among the first to introduce you to a new medication, sildenafil citrate, being tested in the United Kingdom, Europe, and the United States. It was hoped that this new drug would help the more than thirty million men in the U.S. and hundreds of millions of men throughout the world who were suffering from erectile dysfunction (ED).

When I wrote Male Menopause, few took note when I reported the results of my colleague, Stephen M. Auerbach, M.D., on a new medication being developed by the pharmaceutical company, Pfizer. "Thus far, the research has been very positive," said Dr. Auerbach when I interviewed him three years ago. "It has helped 90 percent of my patients who have taken it, and there seems to be few side effects." Few knew then, though most know now, that sildenafil citrate, being marketed under the name Viagra, would become, perhaps, the most important medical breakthrough on male sexuality of the century.

I told you then that research on male menopause was just beginning and that we would know much more over the next few years. I am pleased to be able to give you the most up-to-date information available on this emerging new field of study. Specifically, included here are six new areas of research that will affect the lives of men and women around the world:

1. The latest information for men and their partners in treating erectile dysfunction, including the most recent findings on Viagra, Vasomax, and other new medications being researched.
2. New information on enhancing sexuality for men and women over forty, including studies on Viagra for women.
3. Hormone replacement therapy for men, including the latest research on testosterone replacement therapy for men experiencing male menopause.
4. New approaches for understanding and treating depression in men, including studies that show that male and female depression are often quite different.
5. Findings from the emerging field of vitality and longevity medicine, including research showing that we may soon be able to halt or reverse the aging process.
6. News from the front line from those who have been living with male menopause, including a major shift in the way male menopause is seen by the medical profession.
