title: [Overview on synthetic steroid hormone-chemistry and definition].
abstract: Synthetic steroids are reviewed in terms on "synthetic", "steroid" and hormone. Natural steroids are also synthesized but, are not included in this review, because "synthetic" is rather well defined by the term "not natural". A short history of development of "not natural" steroids are described for the better understanding. "Hormone" is defined more broad in this review. Finally, a classification of steroids under use are proposed. It should be stressed that some of the synthetic steroids are no more hormones and regarded as a foreign substance to the human.
