This timely resource offers extensive discussions on the pharmacological, environmental,endocrinological, and natural factors that alter reproductive or developmental processes-elucidating the effects of toxicants on mechanisms of reproduction. Describing biological actions common to both genders as well as gender-specific processes, Reproductive and Developmental Toxicologyprovides an overview of the basic biology and physiology of organ systems affected by toxicants furnishes detailed examples of developmental toxicology analyzes germ cell toxicity and infertility covers the developmental effects of neurotoxicity considers periods of exposure and long-term toxicological consequences explains how gonadal processes may be susceptible to toxicants in other reproductive organ systems and more!With over 3700 bibliographic citations and more than 100 photographs, drawings, and tables, Reproductive and Developmental Toxicology is a useful reference for toxicologists; reproductive, developmental, cell, and molecular biologists; endocrinologists; biochemists; obstetricians/gynecologists; pediatricians; pharmacists and pharmacologists; physiologists; geneticists; poison control specialists; and upper-level undergraduate, graduate, and medical school students in these disciplines.

Nuclear hormone receptors are not only important drug targets, but have also been the focus of decades of active and highly insightful research. Ten years ago, a review on nuclear receptors was entitled “The Second Decade” and a special issue of Molecular Endocrinology in 2005 dealt with the results of these research efforts. The consensus from nuclear receptor research was of course that the signaling pathways mediated by these receptors warrant further research, even though in principle they appeared to represent the most immediate, seemingly simple signaling pathway from hormone (ligand) binding to gene expression changes. In nuclear receptor molecular biology, estrogen receptor research has additional unique facets: since the discovery of ethinyl estradiol by Inhoffen and Hohlweg in the laboratories of Schering AG in the 1930s—and therefore several decades longer than nuclear receptor - searchitself—estrogenreceptorshavebeentargetsofwidelyused,orally administered drugs. Thus, accumulating clinical experience on estrogen action in vivo helps to support the progress in molecular biological research.

From our current knowledge, it is obvious that estrogen action in­ volves more than reproduction and fertility. Rather, estrogens affect and influence a number of other organ systems such as the immune, cardiovascular and central nervous system as well as the gastrointes­ tinal tract, urinary tract and skeleton. The importance of estrogens and estrogen receptor activity is appreciated from the spectrum of significant physiological dysfunctions that occur when there is a loss The participants of the workshop VI Preface of the hormone or the receptor activity. Loss of estrogen, however (for instance during menopause), occurs with time and results in a variety of clinical conditions. We know that the developmental loss of estrogen, as seen in clinical cases of aromatase gene mutations and experimental models, has dramatic effects in both men and women alike. The evidence that these effects are mediated through the estrogen receptor(s) is based on similar but not always identical phenotypes as observed in experimental animal models of estrogen receptor mutations as well as the single clinical case of an estrogen receptor alpha mutant patient. Developing an understanding of the spectrum of estrogen in a variety of tissues related to the condition of estrogen loss is a major and highly active clinical as well as basic scientific research area. Following the discovery of a second estrogen receptor and possible receptor ligand-independent activity as well as the genomic and non­ genomic actions of estrogen, it is clear that the mechanisms of the effects of estrogen are multifaceted.
