Even though erectile dysfunction is not a normal aspect of aging, for 50% of men between the ages of 40 and 70 it can be difficult to have a normal and healthy erection.

Drug therapy can be effective in some cases, but there are always side-effects to be cautious about, and many people don’t want to rely on drugs to correct the issue.
