- Dunn is an associate of the Center for Investigative Reporting. Hormones are chemical messengers that travel throughout the body coordinating complex processes like growth, metabolism, and fertility. 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.

Where are hormones produced in the body? Hormones are chemical substances that are produced in one part of an organism but cause effects in other parts. Thus, hormones serve as a means of communication among various parts of an organism. In the human body, most hormones are produced by organs called endocrine, or ductless, glands. The hormones control such important body activities as growth and development.

- A hormone is a chemical substance of an endocrine gland. Endocrine glands, which are also called ductless glans, deposites the hormones into the blood stream. The blood, on its turn, carries the hormones to every part of the body. The sex hormones are estrogen and testosterone. Like all hormones, they are chemical messengers, substances produced in one part of the body that go on to tell other parts what to do. Both women and men produce both estrogen and testosterone, though in different quantities, and both sexes produce less as they age.
