This volume represents the Proceedings of the World Conference on Embryo Transfer, In Vitro Fertilization and Instrumental Insemination held on September 24-27, 1980 in Kiel, West Germany. Professor Dr. L. Mettler and Dr. H. H. Riedel of Frauenklinik der UniversiUit in Kiel were the local co- chairpersons, who contributed very richly to the program. Basic research, clinical trials, preparation of manuscripts, editorial assistance and presentation of results were generously supported by the following institutions and organizations: Kulturministerium des Landes Schleswig-Holstein Medizinische FakuItat der Christian-Albrechts-UniversiUit, Kiel Wayne State University School of Medicine; Detroit, Michigan, USA C.

Sincere appreciation and gratitude are due to the contributors who meticulously prepared their chapters; to Ms Jackie Mucci for editorial skills and assistance, and Ms. Jackie Smieska for editorial help. Thanks are also due to Dr. H. D. Brackebusch for his assistance during the conference; to Ms. E. Seiss for her secretarial assistance; and to Mr.

Andrology, a counterpart to gynecology, deals with the study of the male reproductive organs.

During the past decade extensive investigations have been done on the testis. Since the observations have been published in many different journals. it seemed appropriate to bring together and summarize some of the pertinent findings in a single volume. Twenty-eight scientists and clinicians from nine countries have contributed to this book. They have reviewed the literature and presented their own, new observations on the developmentaL anatomicaL physiologicaL biochemical and pathological aspects of the descended and cryptorchid testis. In addition, several contributors have evaluated the usefulness of certain animals as models for systematically studying specific aspects of cryptorchidism. It is hoped that this volume will serve as a useful summary and reference for those working in this area and that it will encourage further research in testicular physiopathology. The editor thanks the contributors for their enthusiasm, cooperation and meticulous writing of the chapters. The support of the Departments of GynecologyjObstetrics and the Department of Physiology of Wayne State University School of Medicine. Detroit and the assistance from the staff of Martinus Nijhoff are gratefully acknowledged. The cheerful cooperation of Miss Lori Rust and Miss Penny Stoops who helped to type and assemble the volume is most deeply appreciated.

The subject matter in this volume was derived from papers presented at the Pediatric Andrology session of the 1st Pan American Congress of Andrology held in Caracas, Venezuela in February 1979, as well as from selected additional manuscripts of interest in this field.
