Cells of the zona fasciculata and zona reticularis lack aldosterone synthase (CYP11B2) that converts corticosterone to aldosterone, and thus these tissues produce only the weak mineralocorticoid corticosterone. However, both these zones do contain the CYP17A1 missing in zona glomerulosa and thus produce the major glucocorticoid, cortisol. Zona fasciculata and zona reticularis cells also contain CYP17A1, whose 17,20-lyase activity is responsible for producing the androgens, dehydroepiandosterone (DHEA) and androstenedione. Thus, fasciculata and reticularis cells can make corticosteroids and the adrenal androgens, but not aldosterone.

While there are a myriad of hormones responsible for an almost infinite number of physiological functions, the hormones listed above are directly influenced by physical activity and play important roles in helping the body adapt to the imposed physical demands of exercise. Many fitness professionals understand that the nervous and muscular systems play important roles in determining the outcomes of an exercise program. However, the reality is that hormones influence many of the physiological adaptations to physical activity. That means that, “It’s all hormones nowadays,” is the appropriate response to many questions about how the human body responds to exercise. 

Anabolic steroids are synthetic substances related to male sex hormones (androgens). Although it is illegal in the United States to possess or distribute anabolic steroids for nonmedical use, a "black market" for them exists, and many amateur and professional athletes take them to enhance performance. In many cases, the athletes take doses that are extremely high—perhaps 100 times the doses that might be prescribed for medical use. As a result, they put themselves in real danger of short-term and long-term health problems. Blood testing, as has been used in the Olympic Games, can detect, identify, and quantify the presence of anabolic steroids in the blood of athletes, which can lead to the disqualification of an athlete.

  2. Carcinoma of the breast in females with hypercalcemia ; androgenic anabolic steroids may stimulate osteolytic resorption of bone .
  3. Nephrosis or the nephrotic phase of nephritis .
  4. WINSTROL (anabolic steroids) can cause fetal harm when administered to a pregnant woman.
WINSTROL (anabolic steroids) is contraindicated in women who are or may become pregnant. If this drug is used during pregnancy , or if the patient becomes pregnant while taking this drug, the patient should be apprised of the potential hazard to the fetus .

The gains made by athletes in uncontrolled observations have been much more impressive. Weight gains of thirty or forty pounds, coupled with thirty percent increases in strength, are not unusual. Such case studies lack credibility because of the absence of scientific controls. However, it would be foolish to completely disregard such observations because the "subjects" have been highly trained and motivated see the articles on pharmacology of sport and sports medicine in the countries of the former Soviet Union for more information on anabolic steroids.
