Future research

Research in erectile dysfunction continues the search for new and better treatments. Some researchers are attempting to identify new molecular targets for treatment of ED, especially for diabetic men. Others are working on new ways to protect against infection after the surgical implantation of devices. Gene therapy may someday provide a way not only to make erections possible, but to restore more normal function. However, it is likely to be a long time before research in gene therapy results in practical treatment options.

Currently, researchers are reporting that ED and heart disease appear to be linked. It is even possible that ED appears in some men as the first sign of disease that eventually will affect the arteries leading to the heart. This research is still preliminary. However, it is supported by reports that reducing lifestyle risks for cardiovascular disease (for example, by losing weight, stopping smoking, reducing cholesterol levels) may help alleviate ED, or help make treatments for ED more effective.
