Evidence of intergenerational transmission of diethylstilbestrol health effects: hindsight and insight

Abstract

Abstract This review summarizes key findings from the US National Cancer Institute (NCI) diethylstilbestrol (DES) Combined Cohort Study with a focus on the results of the NCI Third Generation Study, a cohort of DES-exposed and -unexposed granddaughters. Findings to date from the Third Generation Study are discussed in the context of other research efforts and case reports, suggesting an intergenerational heritability of DES-related effects. The DES story serves as a model for the influence of endocrine disrupting chemicals on human health. It also serves as a warning of the special hazards of pregnancy exposures, and more broadly, of the potential for invisible health consequences arising from new or changing exposures.
