Since then our understanding of the hormone that turns males into men has tremendously increased. Therefore, the editors felt that a second extended edition of the book is warranted in order to summarize established and recent findings in the field and to present the reader with an up-to-date textbook. The increased mass of knowledge is reflected by the growth of the volume from 14 to 20 chapters. In the updated edition the biochemistry and metabolism of androgens have been complemented by extensive information on the molecular biology of the androgen receptor and its disorders. The key role of testosterone in spermatogenesis is now better de fined. We have a more complete understanding of the psychotro pic effects of testosterone and know so much about the different target organs and functions that individual chapters deal with testosterone and the prostate, lipids and the cardiovascular sys tem, hair, bones and muscles. The general chapter on pharmacol ogy and clinical uses of testosterone, in particular in male hypo gonadism, is extended by pharmacokinetic studies on testoster one preparations and individual substitution modalities using testosterone esters as well as implants and advanced trans dermal applications. The physiologic basis and possible clinical applica tions of testosterone in non-gonadal diseases, in male senes cence, in hormonal male contraception and in transsexuals are discussed. The last chapter describes the role of "investigative" steroid biochemistry applied to tracking anabolic steroid abuse. In order to synchronize the writing of the various chapters the authors met on January 22-25, 1998 at Castle Elmau, Bavaria, for final editing of their previously submitted chapters. This guaranteed that all chapters were concluded simultaneously and reflect precisely the state of current knowledge. The contributors deserve our appreciation for their prompt and reliable coopera tion in this venture. We are grateful for a generous grant from SmithKline Beecham Pharma (Munich) facilitating the meeting VI Preface of the authors in combination with a Symposion open to profes sionals interested in the topic. The splendid isolation of Castle Elmau high up in the Bavarian Alps provided a congenial atmo sphere for a productive meeting. Much of the editorial work was performed by Susan Nieschlag M. A. whose untiring professional help is gratefully acknowl edged. Barbel Bahnes, Kerstin Neuhaus and Angelika Schick helped with the word processing of the manuscripts. Finally we would like to thank Dr. Carol Bacchus and the Springer-Verlag for supporting the project and producing the book. Munster/SchloB Elmau, April 1998 Eberhard Nieschlag Hermann M.
