"The Endocrine Society is the world’s largest and oldest professional society dedicated to the understanding of hormone systems and clinical care of those with endocrine diseases including a global membership of physicians and scientists from over 120 countries. Our expertise has defined much of what we know about the endocrine system: what hormones are, what they do and how they do it. Our members have advanced our understanding of how chemicals in plastics can interfere with the function of endocrine systems and act as endocrine-disrupting chemicals or EDCs and cause human and ecological health impacts."
