Investigation of erectile dysfunction. Diagnostic testing for vascular factors in erectile dysfunction.

To date, several accurate tests for diagnosing vascular ED may be chosen. It is necessary to be well aware of the purpose of testing: global assessment of erectile capacity in preparation for auto-injection therapy, or detailed assessment of arterial and erectile response in preparation for surgical treatment. Pharmacotesting may be sufficient for the majority of patients. Other, more invasive tests are reserved for preparing surgical treatment or scientific studies.
