'Eat better and exercise' is true, useless, and the reason most men ignore lifestyle advice entirely. Here is the specific version, ordered by the size of the effect we observe in practice.
1. Treat sleep apnea
This is first because it is the most commonly missed and among the most consequential. Obstructive sleep apnea fragments the sleep architecture during which testosterone is produced and nocturnal erections occur. Men who begin effective treatment frequently report improvement within weeks. If you snore heavily, wake unrefreshed, or your partner has observed you stop breathing, get tested.
2. Stop smoking
Nicotine is directly vasoconstrictive and smoking accelerates endothelial damage. The effect is dose-dependent, and — importantly — partially reversible. Improvement in erectile function is one of the earlier benefits of cessation, often within months rather than years.
3. Aerobic exercise, specifically
The mechanism here is endothelial function, not weight loss, which is why the type of exercise matters. Roughly 160 minutes a week of moderate aerobic activity, sustained over six months, has produced measurable improvement in erectile function in randomized trials. Resistance training has benefits, but not this one.
4. Reduce visceral fat
Abdominal adipose tissue converts testosterone to estradiol and drives insulin resistance and systemic inflammation. Waist circumference correlates with erectile function considerably better than body weight does. A ten percent reduction in body weight has produced meaningful improvement in trial settings.
5. Audit your medication list
- Thiazide diuretics and non-selective beta blockers, where alternatives frequently exist
- SSRIs, where dose adjustment or switching agents may resolve the problem
- Finasteride and dutasteride, which affect a minority of men but affect them significantly
- Certain antihistamines and antipsychotics
Never stop a prescribed medication on your own. Bring the list to us and we will work through it with the physician who prescribed it.
6. Moderate alcohol
Acutely, alcohol impairs the erectile response; chronically, heavy use damages nerves and lowers testosterone. There is no need for abstinence in most men. There is often a need for honesty about the actual weekly quantity.
None of this replaces [treatment](/treatments). All of it makes treatment work better, and some of it makes treatment unnecessary.
