Book Description
The cause of many of the adverse reproductive outcomes and developmental diseases among offspring is not well understood. Most of the epidemiologic and experimental animal research has focused on the relationship between maternal exposures including medications, tobacco smoke, alcohol, infections, and occupation and the occurrence of spontaneous abortion, low birth weight, and birth defects. The potential role of paternal exposures has not been investigated as extensively despite long-standing animal research that demonstrates the induction of mutations in the male germ cell after exposure to certain agents and subsequent reproductive failure or early pregnancy loss. Given this relative lack of interest, acquisition of epidemiologic data and the development of a definitive model or mechanism for potential male-mediated effects has been hindered. However, recent laboratory and epidemiologic investigations have suggested that paternal exposures may be more important than previously suspected. This topic has been termed by some as "male-mediated developmental toxicity. " This is meant to refer to the effects of exposures and other factors relating to the male parent that result in toxicity to the conceptus and abnormal development. The developmental endpoints of interest can include fetal loss, congenital abnormalities, growth retardation, cancer, and neurobehavioral effects. These effects may operate through a variety of mechanisms including gene mutation, chromosomal aberrations, seminal fluid transfer of toxicants and epigenetic events.

Book Description
The issue of male germ line mutagenesis and the effects on developmental defects in the next generation has become increasingly high profile over recent years. Mutations are thought to be becoming more prevalent as a result of: exposure to chemicals in the environment; anti cancer regimes that use genotoxic agents and assisted conception techniques. In addition to the increasing frequency of mutations in the general population, attention is also being given to the effects of epigenetic events on future generations. Male-mediated Developmental Toxicity discusses these issues comprehensively and includes further analysis on the fundamental mechanisms of mutations. With both clinical and experimental sections, written by leading experts in the field, this book will appeal to both medical practitioners and researchers.

Book Description
To safeguard public health, the US Environmental Protection Agency (EPA) must keep abreast of new scientific information and emerging technologies so that it can apply them to regulatory decision-making. For decades the agency has dealt with questions about what animal-testing data to use to make predictions about human health hazards, how to perform dose-response extrapolations, how to identify and protect susceptible subpopulations, and how to address uncertainties. As alternatives to traditional toxicity testing have emerged, the agency has been faced with additional questions about how to incorporate data from such tests into its chemical assessments and whether such tests can replace some traditional testing methods. Endocrine active chemicals (EACs) have raised concerns that traditional toxicity-testing protocols might be inadequate to identify all potential hazards to human health because they have the ability to modulate normal hormone function, and small alterations in hormone concentrations, particularly during sensitive life stages, can have lasting and significant effects. To address concerns about potential human health effects from EACs at low doses, this report develops a strategy to evaluate the evidence for such low-dose effects.

Book Description
Developmental toxicology, an increasingly important area, encompasses the study of toxicant effects on development, from conception through puberty. The Handbook of Developmental Toxicology provides useful insights gained from hands-on experience, as well as a theoretical foundation. In this convenient reference you will find information not previously gathered in one source-including comparative developmental milestones, historical data, and a glossary of terms used in developmental toxicity evaluation. This handbook is a practical guide for individuals who are responsible for testing chemical agents and for regulatory scientists who must evaluate studies, interpret data, and perform risk assessments. Packed with features, the Handbook of Developmental Toxicology is ideal for training students and technicians in developmental toxicology.

Book Description
Have U.S. military personnel experienced health problems from being exposed to Agent Orange, its dioxin contaminants, and other herbicides used in Vietnam? This definitive volume summarizes the strength of the evidence associating exposure during Vietnam service with cancer and other health effects and presents conclusions from an expert panel. Veterans and Agent Orange provides a historical review of the issue, examines studies of populations, in addition to Vietnam veterans, environmentally and occupationally exposed to herbicides and dioxin, and discusses problems in study methodology. The core of the book presents What is known about the toxicology of the herbicides used in greatest quantities in Vietnam. What is known about assessing exposure to herbicides and dioxin. What can be determined from the wide range of epidemiological studies conducted by different authorities. What is known about the relationship between exposure to herbicides and dioxin, and cancer, reproductive effects, neurobehavioral disorders, and other health effects. The book describes research areas of continuing concern and offers recommendations for further research on the health effects of Agent Orange exposure among Vietnam veterans. This volume will be critically important to both policymakers and physicians in the federal government, Vietnam veterans and their families, veterans organizations, researchers, and health professionals.

Book Description
Exposing Men examines how ideals of masculinity have long skewed our societal--and scientific--understanding of one of the pillars of male identity: reproductive health. Only with the recent public exposure of men's reproductive troubles has the health of the male body been thrown into question, and along with it deeper masculine ideals. Whereas once men's sexual and reproductive abilities were the most taboo of topics, today erectile dysfunction is a multi-billion dollar business, and magazine articles trumpet male reproductive decline with headlines such as "You're Half the Man Your Father Was." Cynthia R. Daniels casts a gimlet eye on our world of plummeting sperm counts, spiking reproductive cancers, sperm banks, and pharmacological cures for impotence in order to assess the true state of male health. What she finds is male reproductive systems damaged by toxins and war, and proof piling up that men through sperm, pass on harm to the children they father. Yet, despite the evidence that men's health, as much as women's, significantly affects the vitality of their offspring, Daniels also sees a society holding on to outdated assumptions, one in which men ignore blatant health risks as they struggle to live up to antiquated ideas of manliness.
