EDCs’ effects include disorders of the reproductive system throughout life (abnormalities of sexual differentiation, infertility or subfertility and some neoplasia) and disorders of energy balance (obesity and metabolic syndrome). They could also influence the development of the cerebral cortex. However, the demonstration of the involvement of a single EDC remains difficult in human since we are virtually exposed to a mixture of several ubiquitous EDCs which are variably persistent in the environment and the body and have lifelong consequences. Moreover, since their dose-response relationship can be non-monotonic, setting a threshold dose for EDCs effects has become meaningless. Pregnant women, newborns and young children appear to be mostly at risk. However, the role of the physician remains difficult and raises several questions: how can we formulate justified, applicable and updated recommendations that are not counterproductive or alarmist…in a society that has to take the necessary steps to regulate production and protect the population?
