From the judges' comments in awarding this book (joint) mention of "exceptional merit" in the Society for Sexual Therapy and Research Professional Book Awards 2010:This is an extraordinarily complete and thorough coverage of our area, from both the research and clinical viewpoints. The book is elegantly written with loving and rigorous attention to empirical data. Chapter 2, on the role of theory, is an important contribution and should be required reading for all sex therapists. There is an abundance of material on physiology, population studies and cross-cultural findings. Bancroft has done a remarkable work of reviewing the last several years of research in sexology, proposes resolutions of conflicting results, and offers guides for therapy from research findings.
