Abstract
Anabolic steroids are extensively abused as ergogenic aids by athletes (and others). A number of features of anabolic steroid use and toxicology have been recently reviewed in the Journal, and a large body of data has accumulated concerning their toxic nature. The lipoprotein profile induced by anabolic steroids carries a markedly adverse cardiovascular risk. Glucose metabolism is significantly altered and includes peripheral insulin resistance, hyperinsulinaemia and attenuated responses to glucagon. Hypertension has been noted. Psychiatric and psychological alterations are major toxicities of anabolic steroids, and probably constitute the major mechanism of their action. Hepatic neoplasia occurs in the setting of abuse of this class of drugs, and may be related to their use, although there is no convincing evidence that other malignancies are induced in athletes who abuse them. Gross disturbance of reproductive function occurs in both sexes: hypogonadal states are common and prolonged. The anabolic steroids are toxic drugs with both long and short term effects. Their abuse by athletes is to be decried, particularly in view of the frequent and prolonged use by the young.
