Many reproductive and developmental health problems are caused by exposure to chemicals that are widely dispersed in our environment. These problems include infertility, miscarriage, poor pregnancy outcomes, abnormal fetal development, early puberty, endometriosis, and diseases and cancers of reproductive organs. The compelling nature of the collective science has resulted in recognition of a new field of environmental reproductive health. Focusing on exposures to environmental contaminants, particularly during critical periods in development and their potential effects on all aspects of future reproductive life-course, this book provides the first comprehensive source of information bringing together the arguments that are spread out among various scientific disciplines in environmental health, clinical and public health fields. It provides a review of the science in key areas of the relationship between environmental contaminants and reproductive health outcomes, and recommendations on efforts toward prevention in clinical care and public policy.

This book will focus on the harmful effect of environmental toxins on female reproductive health. Reproduction is the basis of the continuation of human beings, and environment is the basis of human survival. However, environmental pollution has become a potential risk factor for human reproductive health, which not only leads to many chronic diseases, but also causes certain harm to reproductive health. Compared to male reproduction, female reproductive process is more complex, the reproductive system is more fragile, and is more vulnerable to be damaged. The aim of this book is to review the research progress, to address the challenges, and to stimulate the development in the direction of environment and female reproductive health.

Some investigators have hypothesized that estrogens and other hormonally active agents found in the environment might be involved in breast cancer increases and sperm count declines in humans as well as deformities and reproductive problems seen in wildlife. This book looks in detail at the science behind the ominous prospect of "estrogen mimics" threatening health and well-being, from the level of ecosystems and populations to individual people and animals. The committee identifies research needs and offers specific recommendations to decision-makers. This authoritative volume: Critically evaluates the literature on hormonally active agents in the environment and identifies known and suspected toxicologic mechanisms and effects of fish, wildlife, and humans. Examines whether and how exposure to hormonally active agents occursâ€"in diet, in pharmaceuticals, from industrial releases into the environmentâ€"and why the debate centers on estrogens. Identifies significant uncertainties, limitations of knowledge, and weaknesses in the scientific literature. The book presents a wealth of information and investigates a wide range of examples across the spectrum of life that might be related to these agents.

The world population surpassed the seven billion mark in 2011, yet many women and couples still lack access to reproductive health services. These facts have profound implications for maternal and child health, environmental quality, and food security. Global Population and Reproductive Health provides an introduction to an important and timely public health topic. The text is unique in that it explores the inextricable link between population and reproductive health – a connection that is often overlooked – as well as their impact on global and local environmental issues. Students will come away with a clear understanding of the relationships among all these issues, and the vital need for integrated policies and international cooperation. Contents Include: 1. Overview 2. Measures and Theories 3. Health 4. Related Issues 5. Policies

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

In the tradition of Silent Spring and The Sixth Extinction, an urgent, meticulously researched, and groundbreaking book about the ways in which chemicals in the modern environment are changing—and endangering—human sexuality and fertility on the grandest scale, from renowned epidemiologist Shanna Swan. In 2017, author Shanna Swan and her team of researchers completed a major study. They found that over the past four decades, sperm levels among men in Western countries have dropped by more than 50 percent. They came to this conclusion after examining 185 studies involving close to 45,000 healthy men. The result sent shockwaves around the globe—but the story didn’t end there. It turns out our sexual development is changing in broader ways, for both men and women and even other species, and that the modern world is on pace to become an infertile one. How and why could this happen? What is hijacking our fertility and our health? Count Down unpacks these questions, revealing what Swan and other researchers have learned about how both lifestyle and chemical exposures are affecting our fertility, sexual development—potentially including the increase in gender fluidity—and general health as a species. Engagingly explaining the science and repercussions of these worldwide threats and providing simple and practical guidelines for effectively avoiding chemical goods (from water bottles to shaving cream) both as individuals and societies, Count Down is at once an urgent wake-up call, an illuminating read, and a vital tool for the protection of our future.

What is healthy sperm or the male biological clock? This book details why we don't talk about men's reproductive health and how this lack shapes reproductive politics today. For more than a century, the medical profession has made enormous efforts to understand and treat women’s reproductive bodies. But only recently have researchers begun to ask basic questions about how men’s health matters for reproductive outcomes, from miscarriage to childhood illness. What explains this gap in knowledge, and what are its consequences? Rene Almeling examines the production, circulation, and reception of biomedical knowledge about men’s reproductive health. From a failed nineteenth-century effort to launch a medical specialty called andrology to the contemporary science of paternal effects, there has been a lack of attention to the importance of men’s age, health, and exposures. Analyzing historical documents, media messages, and qualitative interviews, GUYnecology demonstrates how this non-knowledge shapes reproductive politics today.
