What Causes Erectile Dysfunction in Men?
Erectile dysfunction (ED) isn’t just a problem for older men. According to research, 11.3% of men aged 30–39 experience some level of ED — and this number is rising in today’s fast-paced lifestyle, with increasing stress and cumulative risky behaviors.

1. Stress and Mental Health Issues
Stress, anxiety, depression, and even sleep deprivation from overworking can all contribute to ED.
Men with depression are 2.5 times more likely to experience ED.
Sleeping less than 5 hours per night increases ED risk by 15–20%.

Regular smoking increases the risk of ED by 50–60%.
Drinking more than 3 alcoholic drinks per day is associated with long-term erectile problems.

6. Medications With Sexual Side Effects
Certain medications like antidepressants (SSRIs), antihypertensives, and DHT-blockers have been linked to ED when used long-term.
For example, 25–60% of SSRI users report erectile issues.

Conclusion
Erectile dysfunction is often viewed as a concern only for older men, but in reality, men in their 30s and 40s are increasingly affected. Paying attention to early warning signs and consulting a specialist can help identify the root cause and lead to effective prevention and treatment.
