An erection is a plumbing event. A sexual cue releases nitric oxide, the penile arteries relax and open, blood floods the tissue and stays trapped under pressure 1. Those arteries are about a millimetre wide, half the width of the ones feeding the heart, so anything that narrows vessels hits them first 2. Erectile dysfunction and heart disease are usually one problem in two places, showing up here first.
The signal is not soft. Pooled across ninety-three thousand men, erectile dysfunction raised the risk of a future heart attack by 62%, a stroke by 39%, and death from any cause by 25%, independent of age, cholesterol, smoking, and diabetes 3. In men in their forties the jump in new coronary disease was roughly fifty-fold 4. About half of men aged 40 to 70 have some degree of it, doubling each decade past forty 5.
Two tracks, in parallel. Pills restore function in weeks; the workup addresses the disease underneath. One appointment should produce both.
Two speeds. Most men who respond to the pill know it on the first or second real try, not weeks later. The lifestyle side is slower: six months of exercise improves function on its own, more the worse you started 9, and a year or two of Mediterranean eating and weight loss returns about a third of men to normal without medication 8. Erectile dysfunction roughly triples depression; as function returns, the shame-and-avoidance loop with a partner lifts too 10.
The fine print โ when to skip it, and what people get wrong
Never combine a PDE5 inhibitor with nitrates โ chest-pain nitroglycerin, isosorbide, or recreational "poppers." Stacking two vasodilators can drop blood pressure fatally 7.
It's rarely "in your head" after forty; the vessel lining is usually involved, and "just relax" buys the disease time 11. The pills don't create desire, only the response to arousal you already have 12.
A fair trial is four attempts at the top tolerated dose, with real stimulation, not one try after dinner 6. If it still fails, a urologist has second-line options: injections, vacuum devices, an implant.
