The average global population is aging rapidly. Though there are many books on menopause and women's health, none before this one was specific on aging in men, especially with reference to andropause. Andropause can be considered a subject within gerontology, urology, endocrinology, obstetrics & gynecology, and especially primary care medicine. This book is case-based, with each case followed by a discussion of the subject and ending with itemized key points and a bibliography. This book is meant for practitioners who not only need to understand the physiological and biochemical changes of the aging male, but also how to apply the knowledge to the patient.
