REFACE
Recent advances in cellular and molecular biology have markedly increased our
understanding of normal and abnormal hypothalamic–pituitary–testicular function. Like
other volumes in the Contemporary Endocrinology series, the goal of Male Hypo-
gonadism: Basic, Clinical, and Therapeutic Principles is to link current knowledge of
basic biology to the practice of medicine. The development of new methods for testoster-
one replacement has substantially increased the number of men who are seeking to
determine whether they are hypogonadal, and who are using testosterone replacement
therapy, thus mandating a broader understanding of testosterone deficiency.
The chapters of this book were contributed by authors from around the world, and
from various scientific and clinical disciplines, who have devoted their careers to the
study of the physiology and pathophysiology of the male. Thus, this comprehensive and
focused volume is intended for a wide audience encompassing both basic scientists and
practicing clinicians. Its scope will provide a wealth of information for students and
fellows as well.
Chapters 1–3 review the neuroendocrine regulation of testicular function and provide
an overview of Leydig cell steroidogenesis and the normal spermatogenic process in
primates. The causes of gonadotropin deficiency and testicular failure are described in
Chapters 4–10. The impact of chronic illness on testicular function is the focus of Chap-
ters 11–13. Chapter 14 describes the endocrine mechanism for the decline in testicular
function with aging. Chapter 15 summarizes the data supporting an impact of environ-
mental factors on testicular function, whereas Chapters 16 and 17 discuss the testicular
consequences of exercise and obesity. Finally, Chapters 18 and 19 provide an overview
of androgen replacement therapy and an approach to stimulating spermatogenesis in
gonadotropin-deficient men.
I wish to thank the contributors who spent many hours researching, pondering, and
preparing their chapters, which collectively are exceedingly informative and clearly
presented.
