Victor Liu is by far one of the best surgeon’s around. It was my first time seeing him. I had a cyst size of a golf ball in the middle of my chest.

Lifestyle has a major impact on erectile function because erections depend on healthy blood vessels, nerves, hormones, and psychological health. Erectile dysfunction (ED) is often one of the earliest signs of declining cardiovascular or metabolic health. In many men, lifestyle factors contribute significantly to the onset or worsening of ED.
Regular physical activity improves blood flow, vascular health, and testosterone levels, all of which are critical for erections.
Benefits of Exercise
Exercise helps by:
Men who exercise regularly have significantly lower rates of erectile dysfunction.
Best Types of Exercise for Erectile Health
Aerobic exercise
Resistance training
Pelvic floor exercises (Kegel exercises)
Recommended amount
Diet strongly influences vascular health, which directly affects erections.
Diets Associated With Better Erectile Function
Mediterranean-style diet
Key components:
Benefits:
Several studies show men following a Mediterranean diet have lower rates of ED and better response to ED treatments.
Foods That Help Erectile Function
These foods support nitric oxide production and vascular health.
Obesity is one of the strongest lifestyle risk factors for ED.
Excess body fat contributes to:
Men with obesity have approximately 2–3× higher rates of erectile dysfunction.
Weight loss can significantly improve erectile function.
Studies show that losing 5–10% of body weight can improve erections in many men.
Smoking damages the lining of blood vessels (endothelium) and accelerates atherosclerosis, which reduces penile blood flow.
Effects of smoking on erectile function:
Men who smoke have about double the risk of ED compared with non-smokers.
Stopping smoking often leads to measurable improvement in erectile quality within months.
Alcohol has dose-dependent effects on erectile function.
Moderate alcohol
May have minimal effect or mild benefit in some studies.
Heavy alcohol use
Often causes ED through:
Chronic heavy alcohol use is a common cause of sexual dysfunction and decreased libido.
Sleep plays a key role in hormone regulation and sexual function.
Poor sleep or sleep disorders such as sleep apnea can lead to:
Most testosterone production occurs during deep sleep, especially in the early morning hours.
Men with untreated sleep apnea have significantly higher rates of ED.
Mental health strongly influences erectile performance.
Common psychological contributors to ED include:
Stress activates the sympathetic nervous system, which interferes with the relaxation of penile smooth muscle required for erections.
Managing stress can significantly improve erectile function.
Helpful approaches include:
Long periods of sitting are associated with:
Men with sedentary lifestyles have significantly higher rates of ED.
Even simple changes like walking daily can improve erectile health.
Erectile dysfunction is often an early warning sign of vascular disease.
Penile arteries are smaller than coronary arteries, so reduced blood flow may appear as ED years before heart disease symptoms develop.
For this reason, ED is increasingly viewed as a marker of overall cardiovascular health.
Addressing lifestyle factors can improve:
Clinical Perspective
In many men with mild or early erectile dysfunction, lifestyle improvements combined with medical therapies such as:
Can significantly improve outcomes.
Watching porn can contribute to ED in some men by causing desensitization and altered arousal patterns, making real-life intimacy less stimulating and sometimes increasing performance anxiety. However, porn is not the main cause of ED for most men—physical factors (vascular, hormonal, neurological) are often more important.
Complete quitting isn’t always necessary. Moderate use is usually fine, but consider reducing or stopping if you notice weaker erections, need for more extreme content, or less interest in real partners. A 4–6 week break can help determine if it’s a factor. If ED persists, a medical evaluation is recommended.
Below are answers to common questions about our physician-led approach, treatment philosophy, and what to expect when beginning care.
No. BeYounger Clinic is a physician-led medical practice. All care begins with a comprehensive medical evaluation and is provided under physician oversight.
