What causes erectile dysfunction is one of the most common questions men ask when they notice changes in sexual performance. In this video, board‑certified urologist Dr. Kia Michel explains what causes ED, how physical and psychological factors play a role, and why erectile dysfunction can be an early warning sign of more serious health conditions. With over 20 years of experience at Comprehensive Urology in Beverly Hills, Dr. Michel offers trusted, medically grounded insight.

Video Description

What causes erectile dysfunction can vary widely from person to person. In this rapid‑fire Q&A video, Dr. Kia Michel explains that erectile dysfunction occurs when there is inadequate blood flow to the penis during sexual stimulation, resulting in erections that are not firm enough for penetration or sexual satisfaction.

Dr. Michel clarifies that ED can be physical, psychological, or a combination of both. Some men have no measurable physical abnormalities but experience erectile dysfunction due to anxiety, stress, or performance concerns. Others have true physiological causes, including diabetes, high blood pressure, vascular disease, and the natural aging process, all of which can impair blood flow. Hormonal factors, particularly low testosterone, also play an important role in erectile physiology.

Another key point discussed is why ED should never be ignored. Dr. Michel explains that erectile dysfunction is often an early marker of vascular disease and may appear years before symptoms of heart disease or other atherosclerotic conditions. In this way, understanding what can cause impotence may help identify serious underlying health issues early, when intervention can be most effective.
