Biologic Markers In Reproductive Toxicology

This leaves nearly 60% of birth defects for which the etiology is unknown but in which environmental exposure might play a role. For every 3,000,000 U.S. births annually, at least 600,000 embryos or fetuses are aborted spontaneously before the 20th week, and some 24,000 fetuses die before birth. Of live births, nearly 8% are premature, and approximately 7% have low birthweight. Another 3–7% possess some type of malformation. Although the overall incidence of infertility remained stable between 1965 and 1982, infertility among. | Biologic Markers in Reproductive Toxicology Free Executive Summary http www.nap.edu catalog 774.html Free Executive Summary Biologic Markers in Reproductive Toxicology Subcommittee on Reproductive and Neurodevelopmental Toxicology Committee on Biologic Markers Board on Environmental Studies and Toxicology National Research Council ISBN 978-0-309-03979-6 420 pages 7 x 10 paperback 1989 This free executive summary is provided by the National Academies as part of our mission to educate the world on issues of science engineering and health.

Does exposure to environmental toxicants inhibit our ability to have healthy children who develop normally Biologic markers--indicators that can tell us when environmental factors have caused a change at the cellular or biochemical level that might affect reproductive ability--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.
