Erectile dysfunction assessment and testing removes months of guessing and gives you an actual answer, rather than trying random fixes and hoping one works. Most men who eventually go through a proper assessment say the same thing afterwards, they wish they’d done it sooner. It’s usually a conversation and a blood draw, not something to dread.
Erectile Dysfunction Assessment And Testing
ED has dozens of possible contributing causes, vascular, hormonal, psychological, medication-related, and more. Guessing which one applies to you rarely works well; a short, structured assessment usually narrows it down quickly. It also matters for a reason beyond ED itself: persistent erectile difficulty can be an early sign of cardiovascular or metabolic disease, sometimes appearing years before other symptoms. Assessment isn’t just about erections.
The Consultation and History
This is where most of the diagnostic work actually happens. According to the American Academy of Family Physicians, a good assessment covers: how the problem presents, every time, or only sometimes, whether erections happen normally alone or in the morning but not with a partner, a strong pointer toward a psychological component, what’s changed in your health, lifestyle and medications, and how long it’s been going on. This conversation alone often points clearly toward a vascular, hormonal, psychological or mixed cause, before any blood test result comes back.
The 6 Standard Blood Tests Used in ED Assessment
Where blood tests are used, they typically screen for the most common underlying contributors:
- Testosterone (usually a morning sample, sometimes both total and free) — screens for hormonal causes
- LH and FSH — help distinguish where in the hormonal system a problem originates
- Prolactin — elevated levels can affect erectile function and desire
- HbA1c or fasting glucose — screens for diabetes or pre-diabetes
- Lipid profile (cholesterol) — screens for vascular risk
- Thyroid function (TSH) — thyroid imbalances can also affect erectile function
Not every man needs every test, your practitioner or doctor will typically select based on your history and presentation rather than running everything by default.
Questionnaires: The IIEF-5
Doctors and urologists commonly use a validated questionnaire called the IIEF-5 (International Index of Erectile Function, short form) to score the severity of ED consistently, track change over time, and support a diagnosis alongside the clinical picture. It’s a five-question, self-administered tool that’s been in clinical use for decades. If you’d like a formal score, ask your doctor for it directly, we’ve deliberately not reproduced it here, since it’s a specific validated clinical instrument rather than something to complete informally online.
When More Specialised Testing Is Used
For most men, history and basic blood work are enough. In more complex or unclear cases, a doctor or urologist may use additional tools: penile Doppler ultrasound, which assesses blood flow directly, nocturnal penile tumescence testing, which checks whether erections occur normally during sleep and helps separate physical from psychological causes, or, rarely, more invasive vascular studies. These sit outside naturopathic scope and would be arranged through a urologist. According to the workup guidance from Medscape, most men are appropriately managed with history and basic labs alone, with specialist testing reserved for unclear or complex presentations.
A Private Self-Check
Click an answer on each question to see what it might suggest. Not the IIEF-5, and not a diagnosis, just a way to see how ready your situation is for a proper assessment.
Whatever your answers, this isn’t a diagnosis, a structured consultation gives you a much clearer picture than working through this alone.
Frequently Asked Questions
Do I need blood tests before my first consultation?
No. The consultation itself usually determines which, if any, tests make sense for your situation.
Is the IIEF-5 the same as a diagnosis?
No, it’s a scoring tool that supports a diagnosis alongside your history and any test results, not a standalone diagnostic test.
What if my blood tests come back normal?
That’s genuinely useful information too, it points more strongly toward psychological, lifestyle or vascular causes that don’t always show on standard blood work, and helps focus the assessment.
Will I need an ultrasound or more invasive testing?
Most men don’t. It’s typically reserved for cases where the cause remains unclear after history and basic blood work, or before certain surgical treatments.
Can this practice order blood tests?
Naturopathic consultations typically work alongside your GP for blood testing; we’ll guide you on what’s worth requesting and help interpret the fuller picture alongside your assessment here.
I’m nervous about what the assessment might find, is that normal?
Very. Most men feel that way beforehand, and most report relief afterwards, uncertainty is usually harder to sit with than an actual answer.

This article provides general educational information and is not a substitute for personalised medical advice, diagnosis or emergency care. This practice does not order specialist tests such as penile Doppler ultrasound or nocturnal penile tumescence testing; where indicated, referral to a GP or urologist is made. Persistent ED, particularly with cardiovascular risk factors present, is a reasonable prompt to have blood pressure, blood sugar and cholesterol checked by a medical doctor.
