Awareness of the importance of sexuality and its disorders in the aging population is increasing as the proportion of older people grows. Based in part on the author's clinical experience and research at Mount Sinai Medical Center in New York, this book presents an up-to-date overview of the sexuality of aging men in health and illness, within a multidimensional conceptual framework, and taking account of physiological, psychological, interpersonal and social influences. Also discussed are the impact of medical illness, psychopathology and drugs, with a review of coping strategies in shaping individual sexual responses to aging and disease. Many case studies and vignettes are incorporated, and a chapter is devoted to the sexuality of older gay men. A balanced account of medical and psychosocial evaluation and treatment concludes the book, which will be of broad interest to clinicians and students interested in sexuality and aging.
