The varied hormones in our bodies exert their effects by attaching to specific receptors. Once this attachment is established, a hormone initiates a unique, complex chain of events that regulate our body’s development and function. Think of each hormone as a member of an orchestra that is performing a demanding, perpetual symphonic work.
Hormone disrupters are chemicals – some naturally occurring, some man-made – that interfere with this delicate process. A disrupter may mimic a hormone, attaching to its unique receptor, then launch an inappropriate action.

The banned pesticide DDT, for instance, interfered with fertility and sexual development in a variety of animals.
Dioxins, chemicals produced in waste incineration, some industrial processes and forest fires, have been shown to disrupt hormonal function in wildlife. Dioxins are widely dispersed in trace amounts; human exposure to dioxins is through food.
