During the past two decades research on the testis has created a vast number of publications. New techniques, such as cell and gene clon ing, germ cell manipulation and transplantation, as well as gene ex pression, have surpassed the classical approaches that involved studies on receptor activation and endocrine, paracrine and autocrine regula tory mechanisms. Due to the expansion of this field of research it has become increasingly difficult to integrate the large number of observa tions and relate them to the physiology and pathophysiology of the tes tis. More emphasis must, therefore, be put on the integration of isolated findings and the construction of the total picture. In order to stimulate this specific mental activity we have named this book Testicular Tan gram. We hope that the chapters in this book will be used as pieces of the testicular puzzle and that the reader enjoys composing new shapes. The chapters of this book are representative of the plenary lectures presented at the I ih European Workshop on Molecular and Cellular Endocrinology of the Testis held in Doorwerth The Netherlands, from April 6 - I 0, 2002. Publication of this book has been made possible by the generous support of the Ernst Schering Research Foundation. We would also like to thank the distinguished scientists, who have pro vided us with their excellent manuscripts well before the start of the Workshop. We acknowledge the help of Dr. U. -F. Habenicht, Dr. M.

Unwanted childlessness affects approximately one in six couples worldwide. - though the exact proportion of the predominant cause of the problem remains controversial, according to the World Health Organization (WHO), in nearly 40% of cases the cause can be attributed to the female, in 20% to the male, in 25% to both, and in 15% the cause remains unknown. Based on these ?gures, the - cidence of male factor infertility in the general population is approximately 7%. The majority of these men, approximately 30%, experience irreversible idiopathic infertility and cannot father children without some form of medical intervention. Male factor infertility, in addition, may be caused by testicular germ cell cancer, which is known to represent the most common cancer among young men, aged 15 to 35 years, in Western industrialized countries. The number of affected men has increased dramatically over the past 50 years. There is now growing evidence that human testicular germ cell cancer originates from fetal germ cells exhibiting an aberrant programme of gene expression, and tumour progression may be favoured by an aberrant Sertoli cell-germ cell communication.

The 3rd edition, the first new one in ten years, includes coverage of molecular levels of detail arising from the last decade's explosion of information at this level of organismic organization. There are 5 new Associate Editors and about 2/3 of the chapters have new authors. Chapters prepared by return authors are extensively revised. Several new chapters have been added on the topic of pregnancy, reflecting the vigorous investigation of this topic during the last decade.The information covered includes both human and experimental animals; basic principels are sought, and information at the organismic and molecular levels are presented. *The leading comprehensive work on the physiology of reproduction*Edited and authored by the world's leading scientists in the field*Is a synthesis of the molecular, cellular, and organismic levels of organization*Bibliogrpahics of chapters are extensive and cover all the relevant literature

Combined oral contraceptives are the most convenient and accepted method of hormonal contraception. Nevertheless, the medical community and consumers constantly demand innovation, additional benefits during use and lower hormonal load despite the high safety profile of available products. At the Ernst Schering Research Foundation Workshop 52, new perspectives and mechanisms for tissue-selective, estrogen-free contraception were discussed. The aim of the workshop was to bring together experts in the field of molecular and pharmacodynamic action of progestins with clinicians and medical experts to discuss potential medical endpoints, physiological reactions and (bio)marker useful describing the tissue selectivity and the contraceptive action of new progestins in different target organs. A major factor for successful realization of these new concepts is a deeper understanding of local pharmacological responses to progestins in general and to new progestins in particular.

Personalized medicine employing patient-based tailor-made therapeutic drugs is taking over treatment paradigms in a variety of ?elds in oncology and the central nervous system. The success of such therapies is mainly dependent on ef?cacious therapeutic drugs and a selective imaging probe for identi?cation of potential responders as well as therapy monitoring for an early bene?t assessment. Molecular imaging (MI) is based on the selective and speci?c interaction of a molecular probe with a biological target which is visualized through nuclear, magnetic resonance, near infrared or other methods. Therefore it is the method of choice for patient selection and therapy monitoring as well as for speci?c e- point monitoring in modern drug development. PET (positron emitting tomography), a nuclear medical imaging modality, is ideally suited to produce three-dimensional images of various targets or processes. The rapidly increasing demand for highly selective probes for MI strongly pushes the development of new PET tracers and PET chemistry. ‘PET chemistry’ can be de?ned as the study of positron-emitting compounds regarding their synthesis, structure, composition, reactivity, nuclear properties and processes and their properties in natural and - natural environments. In practice PET chemistry is strongly in?uenced by the unique properties of the radioisotopes used (e. g. , half-life, che- cal reactivity, etc. ) and integrates scienti?c aspects of nuclear-, organic-, inorganic- and biochemistry.

The current progress in molecular medicine allows the identification of a plethora of new and often human-specific drug targets. An early in vivo validation of specific ligands binding to these targets in humans is needed to assess their potential for targeted imaging and radiotherapy. Radiopharmaceuticals are uniquely suitable for such target validation studies. The purpose of the Ernst Schering Research Foundation Workshop 48 was to offer a forum for an open exchange on the state of the art in the early development of such radiopharmaceuticals. Experts from academia, industry and regulatory authorities provided contributions covering the identification of targets, the necessary preclinical studies on the safety of ligands as well as their validation in human clinical trials.

The interconnectedness of genetics and susceptibility to disease, viral and non-viral inflammation, and the role of immunity and the development of autoimmunity is a fascinating and much discussed topic in cardiomyopathy. This publication constitutes the outcome of an ESRF meeting held together with the German Research Foundation. Clinical researchers, immunologists, virologists and molecular biologists provide the latest findings in their fields, advancing our understanding of what causes chronic viral and inflammatory cardiomyopathy, why it affects a subset of individuals while sparing the majority, how we can develop better therapies, and whether the disease can be prevented. Special emphasis is placed on the role of viruses in the aetiology and pathogenesis of cardiomyopathy. The editors are convinced that the broad spectrum covered by this state-of-the-art publication will be of exceptional value to its readers.
