This fascinating new book explores the myriad aspects of biological theories of sexual preference. Sex, Cells, and Same-Sex Desire describes, reviews, and questions recent biological research on sexual preference from the point of view of knowledgeable scientists and of scholars in the social sciences and humanities representing the emerging field of gay studies. The issues involved have a vibrant history, are wide-ranging, and remain the objects of much controversy. This book demystifies biological research on sexual preference and makes it accessible to readers unfamiliar with biological and medical research. Sex, Cells, and Same-Sex Desire is divided into several sections, each of which is introduced by an explanation of key concepts and terms found in that section. The book begins with a discussion of the history of biological theories and sociocultural concepts of gender and sexuality. The next 3 sections explore specialized areas of biological science and related issues: genetics and evaluation, hormones and the endocrine system, and brain physiology and structure. A final section discusses social stigma, science, and medicine. A glossary of terms used by the authors is included, so readers may look up those that may be unfamiliar.
