Addiction: Anabolic- Androgenic Steroids Anabolic steroids, technically known as anabolic-androgenic steroids, are drugs that are related to the cyclic steroid ring system and have similar effects to testosterone in the body. They increase protein within cells, especially in skeletal muscles. They address the development and maintenance of masculine characteristics such as the growth of the vocal cords, testicles and body hair. Anabolic steroids were first made in the 1930s, and are now used therapeutically in medicine to stimulate bone growth and appetite, induce male puberty and treat chronic wasting conditions; such as cancer and AIDS. The American College of Sports Medicine acknowledges that AAS, in the presence of adequate diet, can contribute to increases in body weight, often as lean mass increases and that the gains in muscular strength achieved through high-intensity exercise and proper diet can be additionally increased by the use of AAS in some individuals. Health risks can be produced by long-term use or excessive doses of anabolic steroids. These effects include harmful changes in cholesterol levels, acne, high blood pressure, liver damage, and dangerous changes in the structure of the left ventricle of the heart. Conditions pertaining to hormonal imbalances such as gynecomastia and testicular atrophy may also be caused by anabolic steroids. Ergogenic uses for anabolic steroids in sports, racing, and bodybuilding as performance-enhancing drugs are controversial because of their hostile effects and the potential to gain unfair advantage is considered cheating. Their use is referred to as doping and banned by all major sporting bodies. Mechanism of action The pharmacodynamics of anabolic steroids are unlike peptid... ...ses the production of red blood cells. Through a number of mechanisms anabolic steroids stimulate the formation of muscle cells and hence cause an increase in the size of skeletal muscles, leading to increased strength. The androgenic effects of AAS are numerous. Depending on the length of use, the side effects of the steroid can be irreversible. Processes affected include pubertal growth, sebaceous gland oil production, and sexuality. Some examples of effects are growth of the clitoris in females and the penis in male children, increased vocal cord size, increased libido, suppression of natural sex hormones, and impaired production of sperm. Effects on women include deepening of the voice, facial hair growth, and possibly a decrease in breast size. Men may develop an enlargement of breast tissue, known as gynecomastia, testicular atrophy, and a reduced sperm count.
