Shawn Dohertyâ??s article on Prof. Nancy Langstonâ??s book, â??Toxic Bodies: Hormone Disruptors and the Legacy of DES,â? didn’t make reference to the pioneering work done by Theo Colborn, as evidenced in her book, â??Our Stolen Future: Are We Threatening Our Fertility, Intelligence, and Survival? A Scientific Detective Story.â? Published in 1996, Colbornâ??s book builds on decades of research, tracing birth defects, sexual abnormalities and reproductive failures to their sources — synthetic chemicals that mimic natural hormones, upsetting normal reproductive and developmental processes.
