Who We Are


EDC History | Common EDCs and Where They Are Found | Frequently Asked Questions


In 2009, alarmed by discoveries in new research, the Endocrine Society set a precedent for dozens of scientific and medical organizations by being the first to take a public stance on endocrine-disrupting chemicals (EDCs). In 2015, we reviewed the latest science and developed a comprehensive Scientific Statement on what was known and what gaps existed in EDC research. Our statement:

  • Defined an EDC as a compound that, through environmental or developmental exposure, alters how an organism communicates and responds to the environment
  • Asserted that there is no endocrine system that is immune to EDCs and that the effects may be transmitted to future generations (i.e., transgenerational)
  • Declared that the evidence for adverse reproductive outcomes is strong and mounting for effects in areas such as neuroendocrine, sexual development, obesity, metabolism, thyroid systems, and insulin resistance
  • Highlighted the “precautionary principle” for informing decisions about exposure and risk: Chemicals must be tested before being introduced into the environment
  • Encouraged scientific societies to partner with organizations with scientific and medical expertise to evaluate the effects of EDCs and communicate to other researchers, clinicians, community advocates, and politicians

This statement reflects our dedication to raise awareness, support research, and advocate for evidence-based regulatory decisions that protect public health and the environment. Combined with the work of our membership, the statement underscores our commitment to improving clinical well-being and furthering our scientific pursuits.
