This book is the product of long years of close collaboration between two physicians, a pediatric endocrinologist and a pediatric surgeon, who are interested in the complex field of human malformations. Their efforts have set a new standard in the treatment of children with intersexual or mal­ formed female genitalia. It is impossible to convey the details of complex surgical procedures without the help of meticulous illustrations. It is fortunate that happened to meet an academically trained artist, Mrs. Siri Mills, M.A., while visiting in the United States. Her excellent knowledge of anatomy, her remarkable skills as an artist and technical illustrator, and her readiness to include all details of interest to the surgeon have found their fruitful expression in the illustrations of this book. We express our thanks to Springer-Verlag and especially to Prof. Diet­ rich Goetze, at whose suggestion this book was written, for their amiable compliance with all our wishes, and particularly for their willingness to retain Mrs. Mills as our illustrator.
