Endocrine Disruptors Certain compounds are likely to act as endocrine disruptors not only by a direct binding to receptorsacting as hormone-mimics (agonists) or as antihormones (antagonists)but also indirectly by modulating endogenous hormone levels by interfering with biochemical processes associated with the production, availability, or metabolism of hormones or also by the modulation of receptors.

It may either increase or decrease the stimulus, but the stimulus is not allowed to continue as it did before the receptor sensed it. Furthermore, the case history of TBT provides evidence for vertebrate-type steroids playing an important functional role in a number of invertebrate groups, including prosobranchs. B.sc.
