Low testosterone can cause a noticeable decrease in sexual drive, as well as erectile dysfunction, according to WebMD. In cases where your ED can be traced to low levels of testosterone, the problem can often be resolved by hormone replacement therapy.
Several forms of testosterone replacement therapy are available. These include transdermal skin patches, such as Androderm; gels such as AndroGel, Axiron, Fortesta, and Testim that are applied directly to the skin; injections and implants; and a mouth patch, such as Striant. Also available are testosterone tablets, which some medical professionals avoid because they can adversely affect the liver.
Although the benefits usually outweigh the risks of testosterone replacement, you and your doctor will have to make the final decision as to whether this form of treatment is advisable for you. One side effect of this therapy is an increase in red blood cell count, which can increase the risk of stroke.
