Atlas on the Human Testis by Davor Ježek Pdf

Atlas on the Human Testis: Normal Morphology and Pathology presents histological illustrative material from paraffin and semi-thin sections of the human testis which are routinely used in the assessment of testicular morphology, allowing an early detection of carcinoma in situ and more advanced pathological changes of the testicular parenchyma. The early detection of cancer in situ is based on the careful morphological investigation of the biopsy and immunohistochemistry (IHC). Therefore, this atlas contains detailed descriptions of IHC methods as well as modern molecular biological methods such as DNA microarrays and proteomics and advanced microscopy techniques related to the testicular biopsy. Adequate evaluation of the testicular biopsy leads to high cure rates of testicular neoplasms which can be used as a basis to successfully treat infertility in men. Atlas on the Human Testis: Normal Morphology and Pathology is a valuable reference tool which will appeal to andrologists, urologists, pathologists, clinical embryologists, as well as reproductive biology scientists.

Descent of the Testis by John M. Hutson,Jørgen Mogens Thorup,Spencer W. Beasley Pdf

This book provides a state of the art overview of all aspects of testicular descent and cryptorchidism, including the mechanisms of descent and the causes, consequences, diagnosis, and treatment of undescended testis. The advances in understanding that have been achieved over the past two decades are clearly explained, covering the latest genetic information on the causes of normal and abnormal testicular descent, the role of INSL3 in transabdominal migration, and the evidence that a neurotransmitter released from the genitofemoral nerve mediates androgenic control of inguinoscrotal descent. Exciting changes in the management of both congenital and acquired cryptorchidism, such as the widespread use of laparoscopy for impalpable testes inside the abdominal cavity, are fully described. Evidence for the benefits of orchidopexy within the first year of life is reviewed, and an individual chapter is also devoted to hormonal treatment. Throughout the book due attention is given to ongoing controversies and divergences of opinion. This new edition of Descent of the Testis will be a timely update and valuable reference for all who are involved in research into testicular descent and management of cryptorchidism.

The Cryptorchid Testis by Thomas O. Abney,Brooks A. Keel Pdf

Current knowledge concerning both morphological and functional cryptorchid-related alterations in the various testicular compartments is summarized in this valuable new publication. Damage to the germinal epithelium and resulting infertility in both humans and experimental animals as well as the degree of damage to the different stages of germ cell development is discussed. In addition, information concerning hormonal therapy and orchidopexy to reverse cryptorchid-related damage is provided. Morphological alterations in Sertoli and Leydig cells is discussed in terms of cellular hypertrophy and hyperplasia, alterations in organelle number and characteristics as well as changes in cell-cell junctional complexes. Changes in Sertoli cell and Leydig cell function, including gonadotropin binding, steroidogenesis and other metabolic alterations is also outlined,as well as the influence of altered testicular function on subsequent hypothalamic-pituitary changes. Vascular disruption, the potential role of paracrine substances and direct thermal damage, all of which may be responsible for the resulting detrimental changes in one or more testicular compartments, are considered.

The Testicular Descent in Human by K.J. Barteczko,M.I. Jacob Pdf

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.

Cell and Molecular Biology of the Testis by Claude Desjardins,Larry L. Ewing Pdf

This book is a comprehensive, multi-authored work on the structure and function of the mammalian testis. The approach emphasizes gene expression, translation and production of specific gene products and the cellular and molecular regulation of these fundamental processes. Rather than provide a global survey of all aspects of male reproduction, this book stresses specific mechanisms that underscore the structure and function of the testis. It explains old and new concepts from a cellular and molecular perspective. This novel approach allows the authors to forge links between cell and molecular biology and well-established aspects of spermatogenesis and steroidogenesis. The result is a well-focused, comprehensive, and synthetic analysis of testicular biology.

Scrotal Pathology by Michele Bertolotto,Carlo Trombetta Pdf

Scrotal Pathology is a comprehensive practical guide to the management of patients who present with scrotal disorders. Introductory chapters consider imaging instrumentation, clinical evaluation, and clinical and imaging anatomy. The full range of disorders is then discussed in individual chapters organized according to clinical presentation. All clinical and imaging aspects are covered in depth, with full description of symptoms and explanation of the value of different clinical tests and imaging modalities. In addition, underlying histopathological features are presented and correlated with imaging features in order to clarify their pathological basis. For each disorder, therapeutic strategies are discussed and appraised. Adults and children are considered separately whenever necessary, bearing in mind that they often present essentially different scrotal pathology. The many images are all of high quality and were obtained using high-end equipment.

The Testis by A.D. Johnson Pdf

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.

Ultrasound of the Testis for the Andrologist by Andrea M. Isidori,Andrea Lenzi Pdf

This book presents a comprehensive study of scrotal ultrasound, helping readers cope with the growing number of pathology pictures revealed by accurate ultrasound examinations, and highlighting the novel applications of contrast-enhanced ultrasonography and elastography. This unique reference guide to scrotal ultrasonography draws on the accumulated expertise of the Experimental Medicine Department at “Sapienza” University, where the andrological ultrasonography unit has performed over 10,000 testicular ultrasound examinations for various conditions and explored experimental new imaging techniques. This core experience has been enriched by insightful contributions from several international experts to form one of the most comprehensive collections of ultrasound images, many in full color, of scrotal pathology in the world. The book’s emphasis on functional interpretation of the images, supplemented by clinical data, make it a unique tool for clinical management. This approach is intended to increasingly familiarize clinicians with the potentials of ultrasonography, from the basics to the most advanced approaches, so as to encourage them to incorporate this examination as a central component of the diagnostic pathway

Cryptorchidism by F. Hadziselimovic Pdf

Ferment, a sign of progress in any scientific field, has previously been lacking in the area of cryptorchidism, where the only activity has been in improving operative methods. Now, however, profound changes in the care of boys with cryptorchidism are being brought about; ideas are arising from a fresh look at comparative anatomy, and histological and experimental observa tions are being supplemented by clinical tests made possible by new hormonal agents. The treatment of cryptorchidism begins with its recognition by the pediatri cian, who until now has shown little interest because of disappointing results from chorionic gonadotropin administration. As for the surgeon, his bent toward restoration of normal anatomical relationships has kept his attention focused on the development of better surgical technics to bring the recalci trant testis into the scrotum. Both specialists have avoided the primordial question of why the testis did not descend properly. If this were known they would treat the cause of cryptorchidism, and not be satisfied merely with trying to correct its end result. As one reads this book, one sees that in most patients cryptorchidism is not caused by some anatomical structure blocking the way or by some deformity of the testis interfering with the transport mechanism. Rather, deficiencies in the hormonal environment of the fetus retard the developmen tal sequences essential to the normal differentiation and descent of the testis. The clinical solution is thus to provide the deficient substances.

Temperature and Environmental Effects on the Testis by Adrian W. Zorgniotti Pdf

It must be considered that there is nothing more difficult to carry out, nor more doubtful of success, nor more dangerous to handle, than to initiate a new order of things. Machiavelli: The Prince (1513) These are the Proceedings of a Conference on Temperature and Environmental Factors and the Testis which took place at New York University School of Medicine, December 8th and 9th, 1989. There is good reason to believe that this was the first of its kind to address, exclusively, the implications of temperature for this highly thermosensitive organ and its precious genetic cargo. The organizers of the Conference hoped to stimulate interest in this area which, paradoxically, has a considerable literature but which has received scant attention and sometimes outright opposition from clinicians expert in male infertility. There have been studies of the relationship of temperature to reproduction starting in the mid-18th Century with observations of the relationship of water temperature to spawning of fish. There is also a vast literature on the deleterious effects of externally applied heat upon spermatogenesis but little study of the possibility that intrinsic heat may be an important etiologic factor in subfertile semen. Today, fertility research has largely ignored this in favor of research in areas which have not produced successes, in terms of live births, comparable to what can be obtained by varicocelectomy (when appropriate) or scrotal hypothermia: viz. 1. Concentration upon the endocrine aspects of testicular function and its relation to spermatogenesis.
