"It is the purpose of this book to survey the most important recent researches in problems of sex, especially those concerned with internal secretions, in order that the concepts already established by experimental evidence may be clearly stated and made readily available. While general principles can in many cases be stated concisely, the recent data have accumulated so rapidly that there has not yet been time for retesting and evaluating much of the evidence. This may account in some chapters for emphasis upon certain work with which contributors may have had personal contacts. Furthermore, sex and reproduction show such wide ranges of variation in both the structures and functions involved that major differences, even among species of higher mammals, make generalizations both difficult and dangerous. This whole field has recently undergone such rapid growth that many new questions have arisen to challenge the investigator's curiosity. An attempt will be made to indicate productive approaches to some of these unsolved or only partially solved problems. This book is intended for the reader with a moderate biological background, to whom the less involved technical terminology may not prove a serious handicap. It is not our intent that it should be a "popular book on sex." Instead, it is designed for those interested in the progress of research in problems of sex, and those who may be already engaged in investigations thereon or casting about for promising problems for investigation"--Preface.
