ABSTRACT
An endocrine disruptor is dened as an exogenous agent that interferes with synthesis, secretion, transport, metabolism, binding action, or elimination of natural bloodborne hormones in the body that are responsible for homeostasis, reproduction, and developmental processes.1 Endocrine disruptors are also called xenobiotics. When they interfere with thyroid homeostasis, they are designated thyroid disruptors (TDs). In a broad sense, those conditions eliciting disruption by xenobiotics (e.g., iodine deciency) may be included as thyroid disruptors or at least co-disruptors.
