Men complaining of low testosterone, a condition known as hypogonadism, will often undergo hormone replacement therapy. As men find the symptoms of this condition becoming more intense and bothersome, they are willing to take medication to improve them. Hormone testosterone replacement therapy is commonly used to alleviate the following hypogonadism symptoms: Erectile dysfunction, less and less interest in sex, decreased energy levels, and loss of muscle mass. Men are aware that these symptoms stem from a condition beyond their control. They may feel helpless, depressed and confused when dealing with them. They often blame themselves and sit silent, thinking there is no treatment unless they get help.
