Testosterone and Physical Function in HIV+ Men

Summary

Men infected with the HIV virus (the virus that causes AIDS) often lose weight even though they may try to eat more food to gain weight. The reasons for this weight loss are not clear. Many men with HIV have low levels of testosterone in their blood. Testosterone is a hormone that is naturally produced in the bodies of both men and women and has important effects on building muscle and bone mass. The purpose of this study is to find out if providing additional testosterone to HIV infected men who have low testosterone can help them gain weight, increase their muscle mass, and feel better. The study will also help see if testosterone improves the efficiency with which your body produces and uses energy including fat. The dose of testosterone being used in this study will raise testosterone levels in the blood to higher than normal levels (2-3 times normal level).
