They can influence the function of the immune system, and even alter behavior.Before birth, they guide development of the brain and reproductive system.ignaling ends when the circulating hormones are broken down and excreted by the body. Hormone disrupting chemicals, or endocrine disruptors, can act at any point along this hormone signaling pathway. Some are hormone mimics: they bind the receptor and send a false signal-one not commanded by the brain.
