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.

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.
This book analyzes the basic science and treatment of male factor infertility with Dr. Silber’s characteristic honesty and clear thinking. It describes finally what works and what doesn’t work. It will inspire everyone in reproductive medicine (Gynecologists, Urologists, Embryologists and Endocrinologists) who wish to better understand male infertility.
This book provides a practical guide to the congenital and acquired problems related to pediatric surgery and urology. A range of topics are covered, including; abdominal wall hernias, hemangioma and vascular malformations, gastrochesis, achalasia, congenital gastric outlet obstruction, renal and liver tumors, intestinal malrotation, and hydronephrosis. The book aims to be a quick reference text for the diagnosis and treatment of pediatric surgery conditions and presents information relevant to general surgeons, pediatricians, pediatric surgeons, and medical trainees.
Written in a simple point by point style for ease of use, this volume covers all aspects of pediatric surgery with emphasis on important points for diagnosis and management. Each chapter covers a topic with emphasis on the most common conditions in neonatal and general pediatric surgery. The text is well illustrated with clinical, operative, radiological, and histopathological color figures and illustrations. The book also presents some of the rare conditions encountered in pediatric surgery, as well as common pediatric urology conditions. An Illustrated Guide to Pediatric Surgery is a useful reference to pediatric surgeons, specialists, fellows and residents, as well as general surgeons, pediatricians, neonatologists, medical students and interns interested in pediatric surgery.
This book provides a comprehensive overview of endocrinology of the male reproductive system, explaining how it works and how, sometimes, it fails to work. World-class specialists present state of the art knowledge on all aspects, including anatomy, physiology, molecular biology, genetics, pathophysiology, clinical manifestations of testicular diseases, endocrine aspects of andrological and sexual diseases, and therapy. Extensive consideration is given to sexual development, testicular function, the clinical approach to disorders of male reproduction, male hypogonadism, sexual dysfunction, and male infertility. In addition, sociodemographic, psychological, and ethical aspects of male reproductive disorders are discussed. The book is intended as a major reference for endocrinologists, andrologists, and sexologists, as well as basic and clinical scientists. It is published as part of the SpringerReference program, which delivers access to living editions constantly updated through a dynamic peer-review publishing process.
Why do testicles hang the way they do? Is there an adaptive function to the female orgasm? What does it feel like to want to kill yourself? Does "free will" really exist? And why is the penis shaped like that anyway? In Why Is the Penis Shaped Like That?, the research psychologist and award-winning columnist Jesse Bering features more than thirty of his most popular essays from Scientific American and Slate, as well as two new pieces, that take readers on a bold and captivating journey through some of the most taboo issues related to evolution and human behavior. Exploring the history of cannibalism, the neurology of people who are sexually attracted to animals, the evolution of human body fluids, the science of homosexuality, and serious questions about life and death, Bering astutely covers a generous expanse of our kaleidoscope of quirks and origins. With his characteristic irreverence and trademark cheekiness, Bering leaves no topic unturned or curiosity unexamined, and he does it all with an audaciously original voice. Whether you're interested in the psychological history behind the many facets of sexual desire or the evolutionary patterns that have dictated our current mystique and phallic physique, Why Is the Penis Shaped Like That? is bound to create lively discussion and debate for years to come.
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.
