An ED assessment usually begins with a conversation and examination, not a single pass-or-fail test. The aim is to understand symptoms, identify possible causes and choose safe next steps with you.
What to bring to your appointment
- A list of prescriptions, nonprescription medicines and supplements.
- A brief note of when symptoms began, whether they are occasional or persistent, and any changes in health.
- Your questions about privacy, treatment preferences and side effects.
Questions your clinician may ask
Expect questions about medical and sexual history, erections, medicines, alcohol, smoking and emotional or relationship concerns. These help put symptoms in context. An examination and selected blood tests may be suggested; additional tests depend on what the assessment shows.
Will everyone need an ultrasound?
No. Specialised tests are used selectively. Ask what a proposed test could show and whether its result would change treatment. Do not buy home tests or choose medicine strengths as a substitute for a clinical assessment.
After the assessment
Ask which possible causes need attention, what treatment options are appropriate, and when to return if symptoms persist. Bring up any cost or access concerns before starting treatment. Do not stop an existing medicine yourself because you think it may contribute to ED.
