Dr. Robert Tan draws upon his many years of treating older men during their Andropausal years to share his personal research findings (superbly illustrated with case histories) to define the Andropausal biological milestone for the aging male; describe the evolving physical, sexual, psychosocial and mental challenges encountered; explain the role of hormones and supplements relevant to the Andropause phenomenon; and offers unique perspectives on memory loss, erectile dysfunction and sexuality during the Andropause. Written with a completely reader friendly and accessible text, The Andropause Mystery is highly recommended to both medical professionals and the interested non-specialist general reader.
