"In this slim and elegant volume, LeVay explores why we are sexual animals, what brain mechanisms produce sexual behavior and how they differ in men and women. He asks `What determines sexual orientation? Genes, events in the womb or nurture?' -- a work of stunning scientific scholarship enhanced by gracious style and modesty."
-- Avodah K. Offit, Los Angeles Times

"Elegantly, even wittily, written [The Sexual Brain] merges evolutionary theory, endocrinology, molecular genetics and cognitive psychology into a synthesis that is brilliant and entertaining."
-- Peter Gormer, The Chicago Tribune

Written with clarity, directness, and humor, The Sexual Brain examines the biological roots of human sexual behavior. It puts forward the compelling case that the diversity of human sexual feelings and behavior can best be understood in terms of the development, structure, and function of the brain circuits that produce them. A new afterword to this paperback edition takes up the work of Dean Hamer and his colleagues who in 1993 produced molecular genetic evidence for the existence of a gene that influences sexual orientation in men.
