Structure and Function of the Gonadotropins
In September of 1977 scientists from many countries met at the Asticou Inn in Maine to present and discuss papers written especially for this monograph. The presentations were informal and directed to the special interests of the audience in order to generate discussions. The authors, many of whom are pioneers and leaders in their field, then had the oppor tunity to revise their contributions, which were brought together with the edited discussions to form this volume. The basic research studies presented here are important because of the essential role of gonadotropins in regulating the ovary and testis. This monograph will therefore be of interest to those concerned with fertility regulation, population control, possible new methods for contraception, and to those concerned with reproduction in domestic animals. Re searchers in other fields may find this monograph useful, as it has been de termined that gonadotropins are secreted by many tumors and are im plicated in many cancers. Human choriogonadotropin also seems to be found in most, if not all, cells of the human body. The significance of this, however, is unknown.
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.
Banking on the Body
Scientific advances and economic forces have converged to create something unthinkable for much of human history: a robust market in human body products. Every year, countless Americans supply blood, sperm, and breast milk to “banks” that store these products for later use by strangers in routine medical procedures. These exchanges entail complicated questions. Which body products are donated and which sold? Who gives and who receives? And, in the end, who profits? In this eye-opening study, Kara Swanson traces the history of body banks from the nineteenth-century experiments that discovered therapeutic uses for body products to twenty-first-century websites that facilitate a thriving gl...
Development, Anatomy, and Physiology
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.
New Approaches To Human Reproduction
This book bridges the gap between cultural values and medical technology, focusing in the areas of conception, birth, and neonatality. It brings together research data and analysis particularly relevant for social scientists as well as nurses, public health professionals, and physicians.

Hormone Binding and Target Cell Activation in the Testis
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....
Regulation of Organ and Tissue Growth
Regulation of Organ and Tissue Growth investigates the mechanisms underlying the regulation of organ and tissue growth. Theories of growth regulation are discussed, along with growth and renewal; factors that influence prenatal brain development; regulation of metabolic and functional properties of muscle; and the role of tension in muscle growth. Heart growth and size in homeotherms are also examined. Comprised of 18 chapters, this book begins with an introduction to two schools of thought that explain the orderly growth of organs and tissues: one contends that the dimensions of body parts are genetically predetermined, while the other holds that the correct size of an organ is a function o...
