Few of us know much about the biology of sex determination, but what could be more interesting than to discover how we are shaped into males and females? In this book, Elof Carlson tells the incredible story of the difficult quest to understand how the body forms girls and boys.

Review quote

"Carlson does an excellent job presenting the researchers who, over time, worked out the details of sex determination and differentiation. Highly informative and instructive." -Johan Verhulst, MD, Kinsey Institute "Carlson reveals the various scientific advances, in both methods and understanding, that allowed researchers to identify anatomical structures, gametes, sex hormones, sex chromosomes, and ultimately, a firm comprehension of the genetics of sex... This scientific story of discovery is quite fascinating." -Barbara Baumgartner, Washington University, St. Louisshow more
