0378-4274/$doi:10.1016/jandrogenic steroids (AAS) are used as ergogenic aids by athletes and non-athletes to enhance performance bymuscular development and strength. AAS administration is often associated with various adverse effects that arese related. High and multi-doses of AAS used for athletic enhancement can lead to serious and irreversible organong the most common adverse effects of AAS are some degree of reduced fertility and gynecomastia in males and

tion in women and children. Other adverse effects include hypertension and atherosclerosis, blood clotting, jaundice,lasms and carcinoma, tendon damage, psychiatric and behavioral disorders. More specifically, this article reviewstive, hepatic, cardiovascular, hematological, cerebrovascular, musculoskeletal, endocrine, renal, immunologic andeffects. Drug-prevention counseling to athletes is highlighted and the use of anabolic steroids is must be avoided,that sports goals may be met within the framework of honest competition, free of doping substances.
