If a pharmaceutical company could put the benefits of regular aerobic exercise into a pill, it would be the best-selling ED drug in history. The evidence for exercise as both prevention and treatment for erectile dysfunction is overwhelming—and summer makes it easier to get than any other time of year.
The Meta-Analytic Evidence
A 2018 meta-analysis in the journal Sexual Medicine reviewed 10 studies encompassing over 600 men and concluded that aerobic exercise significantly improves erectile function in men with ED—with effects comparable to PDE5 inhibitor medications in cases of mild to moderate severity.[1]
Why Swimming Is Particularly Effective
Swimming combines several mechanisms that benefit erectile function simultaneously. The horizontal body position redistributes blood flow toward the core and pelvic region. Water pressure provides a gentle compression that improves venous return. The cardiovascular demand builds endothelial function—the same endothelial cells that produce nitric oxide in your penile arteries.
Unlike running, swimming is low-impact, reducing the barriers that keep many men from consistent exercise. And unlike gym workouts, a summer swim at the beach or pool feels like recreation rather than obligation—which means you’re more likely to actually do it.
The Cycling Question
Cycling gets complicated press regarding ED. The concern about saddle pressure on the perineum is real but highly manageable. Properly fitted seats, appropriate riding position, and regular standing intervals largely eliminate the risk. Meanwhile, the cardiovascular benefits of cycling are exceptional for pelvic blood flow.[2]
A large study published in the Journal of Men’s Health found that recreational cyclists did not have an increased risk of ED compared to non-cyclists, and that the cardiovascular benefits outweighed any pressure-related concerns for most riders.
Outdoor vs. Indoor Exercise
Summer outdoor exercise delivers benefits beyond what a treadmill provides. Sunlight exposure boosts vitamin D and testosterone. Varied terrain improves proprioception and engages more muscle groups. The psychological benefits of nature exposure reduce cortisol—a hormone that directly suppresses testosterone when chronically elevated.[3]
Studies on “green exercise” show that outdoor physical activity produces greater reductions in stress hormones and greater improvements in mood compared to identical exercise performed indoors. Since psychological stress is a major contributor to ED, the outdoor advantage is real and measurable.
The Summer Exercise Prescription
The minimum effective dose for erectile health is roughly 150 minutes per week of moderate-intensity aerobic exercise. In summer terms, that’s five 30-minute swims, three 50-minute bike rides, or some combination of hiking, beach volleyball, surfing, paddleboarding, or whatever gets you moving and enjoying it.
