Treatment may depend on the cause. Low testosterone that causes symptoms usually is treated with testosterone hormone. This is called testosterone replacement. You can get it in different ways, such as in a shot, through a patch or gel on the skin, or in a tablet you place between your cheek and gum.

Another way to raise your testosterone is through pills that you swallow. These pills aren't testosterone. Instead they are other kinds of medicine that work well to raise testosterone levels. They include medicines such as clomiphene.

Testosterone replacement may improve your sexual desire, increase your muscle mass, and help prevent bone loss. Many men with low testosterone levels report that they feel better and have more energy while taking testosterone.

Testosterone may be used to treat some men who have erection problems.
