Does Drinking Water Help with Erectile Dysfunction?
Medically reviewed by Linda Girgis | MD, Girgis Family Medicine on August 20th, 2026.
Drinking adequate water can help with erectile dysfunction by improving blood flow and cardiovascular health. Dehydration reduces blood volume and circulation, which can worsen ED symptoms since erections depend on proper blood flow to penile tissues. Studies show that men who drink 6-8 glasses of water daily have better vascular function than those who are chronically dehydrated. However, water alone rarely resolves moderate to severe ED cases, which typically require medical evaluation to address underlying causes like diabetes, hypertension, or hormonal imbalances. While staying hydrated supports overall sexual health, most men with persistent ED benefit from comprehensive treatment addressing both lifestyle factors and medical conditions.
