In all vertebrates, the thyroid axis is an endocrine feedback system that affects growth,
differentiation, and reproduction, by sensing and translating central and peripheral signals to …

Thyroid hormones (THs) are well-known regulators of development and metabolism in
vertebrates. There is increasing evidence that THs are also involved in gonadal …

Many xenobiotic compounds with endocrine disrupting activity have been described since
the late eighties. These compounds are able to interact with natural hormone systems and …
