Hormone therapy is used by transsexuals to change some secondary sex characteristics, including breast size, weight distribution, and hair growth. Like most aspects of human chemistry, the endocrine system - which controls the body's production and balance of hormones, including sex hormones - is still, at best, only loosely understood. However, one thing is for certain, hormones represent some of the strongest and subtlest chemicals produced by the body and should not be 'messed-with' without extreme care. Always consult a physician before using, or contemplating the use of, sex hormones on your body.

HOR-monezs Sex Chemicals in your body
Hormones are natural chemicals that affect different parts of your body. They travel around your body in your blood. The sex hormones control your growth and sexual development. The main female hormones are called oestrogen and progesterone, the male hormone is called testosterone. At puberty the body starts to change as these hormones are made. The changes start earlier for some people than others, so that some girls will develop breasts, grow pubic hair and start menstruating (having their periods). Some young men will find that their voice grows deeper, they experience erections and have wet dreams. Every person is different - there is no right or wrong time for the changes to happen.
Proteins produced by your body, which move around in your blood. Hormones control how you grow, how you burn up the food you eat, and how you reproduce.

Chemicals found naturally in animals' bodies that control processes like growth and metabolism. Synthetic (man-made) hormones have been developed for a number of purposes, including treatment of hormonal disorders in people, and also for promotion of unnaturally fast growth in farm animals. One of the most well-known and controversial hormones used in farming is recombinant Bovine Growth Hormone or rBGH, which is genetically engineered and injected into dairy cattle. (See rBGH.) Scientists have linked excess hormones to cancer.

messages that can travel long distances around the body from cells in what's called an endocrine gland (eg. the pituitary gland) to cells in 'distant' organs or tissues (eg. the uterus). Immune Complexes - formed when lots of antibodies bind to antigens floating around (see "The immune System"). These should normally be cleared by special macrophages in the liver and spleen with the aid of the complement system. In lupus, immune complexes aren't cleared very well and can get trapped in small blood vessels of the skin and kidneys causing inflammation.

These can be prescription, over-the-counter, synthetic or natural agents. Examples include adrenal hormones such as corticosteroids and aldosterone; glucagon, growth hormone, insulin, testosterone, estrogens, progestins, progesterone, DHEA, melatonin, and thyroid hormones such as thyroxine and calcitonin.
