Spironolactone (Aldactone) may be used with other medicines to treat high blood pressure and heart failure. It may also help people who have too much aldosterone, a hormone, or people who have edema (fluid retention) from heart, liver, or kidney disease.

Testosterone levels gradually decline throughout adulthood â about 1 percent a year after age 30 on average. A blood test is the only way to diagnose a low testosterone level or a reduction in the bioavailability of testosterone. Some men have a lower than normal testosterone level without signs or symptoms. In this case, no treatment is needed.
