What's usually going on
Erections depend on blood flow, nerves, hormones and how you are feeling. Stress, poor sleep, alcohol, some medicines and conditions like high blood pressure or diabetes can all get in the way.
Because the same blood vessels run everywhere, it is also worth a proper look at your general health. The conversation is the hard part, so we have made it a questionnaire.
Wording under reviewClinician sign-off before publishing.
When we open, all of this happens online.
An honest assessment
A short, private online questionnaire about your health and what is happening, reviewed by a UK clinician. No photos, no video unless you want one.
A plan you agree together
If treatment is suitable, your clinician explains the options, how they work and what to expect.
Check-ins that notice change
Your sleep, stress and Daily Debrief sit alongside your plan, because they are often part of the answer.
Five questions. Anonymous. A score and what it means.
The standard IIEF-5, answered in private. Your result stays on screen; a doctor-written report by email is optional.
