Many xenobiotics are considered reproductive toxins because of their ability to interact with the nuclear estrogen receptors (ERalpha and ERbeta). However, there is evidence that these xenobiotics can regulate gene expression in the reproductive targ

Chlordecone (Kepone) is a polychlorinated hydrocarbon that has a low affinity for the estrogen receptor. Although the compound has been shown to be an estrogen antagonist for some responses within the central nervous system, and in hypophyseal gonado
