Why it matters

Erectile dysfunction can be an early marker of cardiovascular disease. Check blood pressure, QRISK3, HbA1c and lipids.

Check a morning testosterone if libido is low or a PDE5 inhibitor has not worked. A PDE5 inhibitor is first line unless contraindicated, for example with nitrates.
