Book Description
Methods in Toxicology, Volume 3: Male Reproductive Toxicology, Part A, deals with the male reproductive system and discusses methods that will help identify toxicant-induced changes at all levels in living organisms. It is important to realize that a toxic effect does not occur in a vacuum. All work in toxicology must be predicated on a demonstrated adverse effect in vivo. If good toxicology cannot exist in a vacuum, then there must be a structure. Thus, the book begins by presenting a few models as examples of the ways experiments could be grouped to define the toxicity of a chemical. This is followed by separate chapters on methods such as male mouse sexual behavior test; in vitro techniques for assessing pituitary secretory function; histological methods for preservation of the rat testis; procedures for assessing testicular sperm head counts in mice, rats, and dogs; and guidelines for conducting rodent dominant lethal tests. Subsequent chapters cover topics such as methods for the isolation and purification of Leydig cells from rat and mouse testes, and techniques used in semen analysis and fertility assessment in the rabbit.

Book Description
The most recent volume in the Drinking Water and Health series contains the results of a two-part study on the toxicity of drinking water contaminants. The first part examines current practices in risk assessment, identifies new noncancerous toxic responses to chemicals found in drinking water, and discusses the use of pharmacokinetic data to estimate the delivered dose and response. The second part of the book provides risk assessments for 14 specific compounds, 9 presented here for the first time.

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
Does exposure to environmental toxicants inhibit our ability to have healthy children who develop normally? Biologic markersâ€"indicators that can tell us when environmental factors have caused a change at the cellular or biochemical level that might affect reproductive abilityâ€"are a promising tool for research aimed at answering that important question. Biologic Markers in Reproductive Toxicology examines the potential of these markers in environmental health studies; clarifies definitions, underlying concepts, and possible applications; and shows the benefits to be gained from their use in reproductive and neurodevelopmental research.

Book Description
Bioenvironmental Issues Affecting Men's Reproductive and Sexual Health is structured into two parts related to men’s reproductive and sexual health with eight sections designed to enable a logical flow of such knowledge. The book is focused on the biology of key organs involved in male reproduction and the environmental influences affecting their functions with particular emphasis on clinical aspects. Individual chapters within the book range from basic to translational aspects, but all hold clinical relevance. This is an essential reference for those working and learning in the field of human reproduction, reproductive toxicology and environmental influences on reproductive and sexual health. Brings together the leading authorities working in the field of male reproduction and sexual health and how the environment affects these issues. Provides guidelines and reference values of various reproductive hormones, semen parameters, inclusion/exclusion criteria for clinical trials. Discover the most efficient methods by which to design clinical protocols for sperm safety studies and reproductive toxicology trials.

Book Description
Physiology and Toxicology of Male Reproduction is a collection of papers that deals with general reproductive biology and specific aspects of reproductive toxicology, pertaining to the male sex. Some papers discuss testicular organization, reproductive toxicity testing systems, and germ-cell genetic toxicology. The use of in vitro systems by investigators to dissect the male reproductive toxicants can lead to a more scientific approach toward hazard assessment and the development of safer drugs and chemicals. Other papers explain the fundamental reproductive biology of the testis, the neuroendocrine system, the epididymis and accessory sex organs, and spermatozoal evaluation. Toxicological aspects cover the toxicological evaluation of the complete reproductive system, testicular morphology, sperm assessment, and germ-cell mutagenesis. One paper describes alternative methods in toxicology—by using new in vitro systems that should reduce or eliminate the need for tests conducted on animals. In vitro methodology embraces other systems such as from subcellular fractions to isolated intact organs. In relation to target-organ toxicity, the researcher can focus using primary cell cultures. This collection will prove helpful to toxicologists, graduate students and researchers in biology, particularly in male reproductive toxicology and fertility testing.
