The Developing Testis' is a complex site of various differentiation events resulting in two main functions in adult life - gametogenesis and androgen biosynthesis. Testis research is multidisciplinary in its nature and attracts both basic and clinical scientists. The purpose of this volume has therefore been to bring together a group of expert scientists in the fields of physiology, endocrinology, pediatrics and andrology to sum up our current knowledge on human testicular development, from the state of male sex determination to the end of puberty. The contents span from molecular events in male sex determination and testis differentiation to clinical entities such as the testis in childhood cancer, cancer in the testis and gonadotropin receptor mutations. Testicular descent and cryptorchidism are reviewed from the eyes of a pediatrician rather than from the traditional surgical view. Exciting recent developments in approaches to prevent male infertility after gonadotoxic cancer treatment in prepubertal boys are reviewed. The book addresses a wide readership among basic scientists, general pediatricians, endocrinologists, urologists, andrologists and others interested in the function of the developing male gonad.

The Testis, Volume I: Development, Anatomy, and Physiology focuses on the study of the testis. Particular concerns include embryology, morphology, physiology, cytology, and anatomy of this complex organ. Composed of contributions of authors that are divided into nine chapters, the book outlines the development of mammalian testis. Areas discussed include differentiation of the testis; genital glands and ducts; and postnatal development. The text highlights the relationship of this organ, along with the scrotum and epididymis, to the nervous system. The book discusses as well the supply of blood; secretion of fluid; and regulation of temperature of the testis. Concerns include testicular lymph and lymphatics; testicular fluid; and rete testis. The discussions proceed with an examination of the intertubular tissue of the testis. The selection ends with the discussions on the structure and functions of the testis. Noted are the presence of different cells and tissues that compose this organ and how these influence its functions. The selection is a good source of information for readers interested in studying the complex structure and functions of the testis.

The Testis, Volume II: Biochemistry focuses on the study of the biochemistry of mammalian testis. Composed of contributions of authors, the book starts with the endocrinology of the testis. Topics covered include testicular estrogens and androgens; the effect of age on testicular steroidogenesis; and endocrine regulation of spermatogenesis. The compilation also presents a histochemical analysis of the localization of testicular enzymes. Covered are histochemistry; enzymes of the fetal and mature testis; and the factors affecting testicular enzymes. The text notes as well that blood flow, hormones, nutrition, age, and temperature can affect testicular lipids and that the testis has testicular proteins and nucleic acids. The selection also outlines the growth and development of mammalian testis, and then ends with the discussions on hormonal regulation; chemical constituents; and testicular development, structure, and spermatogenesis of invertebrate testes. The compilation will best serve the interest of readers interested in studying the structure and functions of the testis.

The testicular descent (descensus testis) is described in a complete series of human material from stage 14 CC to the adult state by using own phases. Central points of interest in this work are answers to questions which have been discussed controversially by generations of scientists and which are wrong or inadequately documented in most textbooks of embryology: Does an inner gonadal descent exist? What about origin, role and fate of gubernaculum H., processus vaginalis peritonei and gonadal ligaments? How do the annexes of testis come into their final position? The results are based on serial sections, scanning electron microscopy, three-dimensional reconstructions, microdissection and immunohistochemistry.

The success of Assisted Reproductive Technology is critically dependent upon the use of well optimized protocols, based upon sound scientific reasoning, empirical observations and evidence of clinical efficacy. Recently, the treatment of infertility has experienced a revolution, with the routine adoption of increasingly specialized molecular biological techniques and advanced methods for the manipulation of gametes and embryos. This textbook – inspired by the postgraduate degree program at the University of Oxford – guides students through the multidisciplinary syllabus essential to ART laboratory practice, from basic culture techniques and micromanipulation to laboratory management and quality assurance, and from endocrinology to molecular biology and research methods. Written for all levels of IVF practitioners, reproductive biologists and technologists involved in human reproductive science, it can be used as a reference manual for all IVF labs and as a textbook by undergraduates, advanced students, scientists and professionals involved in gamete, embryo or stem cell biology.

It is curious that research in endocrinology has largely ignored the testis until quite recently. There were two impor tant reasons for this neglect; first, methods of study were difficult, and second, sperinatogenesis was considered to be the concern of the urologist or cell biologist but not the endocrinologist. Since it is now almost an ethical imperative that we develop a male contraceptive, and since a host of new techniques can be brought to bear on problems of testis function, research in male reproductive biology has effloresced. In fact, it has become possible to project aseries of workshops on the testis, each dealing with discrete aspects of biochemistry, physiology and pathology. It is fitting that this first Workshop should be on Binding and Activation, since this area is one of the frontiers in endocrinol ogy. At our present rate of progress it is probable that each of the succeeding workshops will likewise bring together leaders in a rapidly developing area. The National Institute of Child Health and Human Development has the major Federal respon sibility in reproductive biology, and has therefore agreed to sponsor this and succeeding workshops. On behalf of the Institute and for those members of the Committee who have organized this meeting, I welcome you. I am quite sure that this first Workshop on the Testis will initiate aseries of important contributions to scientific thought in male reproduc tive biology. Mortimer B. Lipsett, M. D.

Cytological techniques have greatly improved in the last twenty years, largely as a result of further development of the microscope. Electron microscopy, in particular, has opened up great prospects for the study of cell morphology, while the develop ment of radio-immuno-assay has brought great progress in endocrinology. The applica tion of these two techniques, which are complementary to each other and provide mutually supporting evidence, is the subject of this monograph. The work is divided into two parts. The first deals with the ultrastructure of normal testicular development, describing four main elements of the testicle - the germ cells, the Sertoli cells, the peri tubular connective tissue and the Leydig cell- with details of their individual development. To make the electron micrographs more easily understandable, diagrams have been used to explain the most important points. The second part deals with cryptorchid testicles, including the primary and sec ondary changes involved and morphometric studies of the secondary changes. The significance of these ultrastructural observations for the treatment of cryptorchidism is emphasized. With the aid of radio-immuno-assay the level of testosterone in cryp torchid mice was determined and comparisons drawn between the ultrastructural changes in cryptorchidism in mouse and man. The experimental studies served as a basis for the hypothesis that, in all probability, a congenital disturbance of the hy pothalamo-hypophyso-gonadal axis is responsible for cryptorchidism. I hope that this monograph will contribute towards a better understanding of normal and cryptorchid testicular development and of the etiology of cryptorchidism.
