Correction: The previous version gave blanket percentage claims about erectile dysfunction and lifestyle. Those figures did not establish an individual risk reduction and have been removed.

There is more than one cause

Erectile dysfunction can involve physical conditions, medicines and psychological factors. It should not automatically be blamed on lifestyle. The NIDDK causes guide describes these different possibilities.

Where exercise fits

Regular physical activity may form part of a clinician's treatment advice, alongside addressing underlying conditions. It is not a universal cure or a substitute for assessment. See NIDDK's treatment information.

Reading a percentage claim

Before applying a study result to yourself, ask who was studied, what changed, how the outcome was measured and whether the number describes a relative change or an absolute one. Improvement on a questionnaire is different from a guaranteed recovery.

For persistent symptoms, discuss them with a healthcare professional rather than buying a treatment from an unverified advertisement. This article provides general source guidance.
