Self-Treatment for ED | Effects and Limits of Foods, Strength Training, and Lifestyle Improvements Explained by a Doctor





I want to treat ED on my own, can I improve it without relying on medication, with food and exercise? Many men have these thoughts. Lifestyle improvements such as exercise, dietary improvement, smoking cessation, and stress management have a certain effect on mild ED and ED caused by lifestyle-related diseases. On the other hand, self-treatment also has its limits, and there is a risk of worsening if left untreated. In this article, our medical team explains the types, effects, and limits of self-treatment methods you can use for ED.

“I want to cure ED (erectile dysfunction) on my own,” “If possible, I want to improve it without using medication” – these voices are heard from many men of all ages.

The internet is full of information such as “foods that work for ED,” “improve ED with strength training,” and “how to cure ED on your own,” but few people accurately understand how scientifically supported these claims are and how much effect can be expected.

In this article, we cover 5 self-treatment approaches for ED – exercise, diet, smoking cessation, stress management, and supplements – and explain the effects and limits of each based on medical evidence. We also introduce cautions for self-treatment and cases where treatment at a medical institution is necessary.

What Is ED? Understanding Its Types and Causes Correctly

Explanation of the types and causes of ED

ED (Erectile Dysfunction) refers to a persistent state in which a man cannot obtain or maintain an erection sufficient for satisfactory sexual intercourse. It includes not only the case of “no erection at all” but also “insufficient hardness” and “losing the erection mid-intercourse (mid-intercourse softening).”

The causes of ED can be broadly classified into 3 categories. Whether self-treatment is possible greatly depends on the type of cause.

Type Cause Possibility of Self-Improvement
Organic ED Vascular disorders, neurological disorders, hormone decline, and other physical factors Triangle: Some improvement possible with lifestyle changes, but pharmacotherapy is the main approach
Psychogenic ED Stress, anxiety, trauma, relationship with partner Circle: Easily improved by stress relief and counseling
Mixed-type ED Combination of organic and psychogenic factors Triangle: Approach from both sides is needed

According to Japanese epidemiological studies, the prevalence of ED is approximately 20% in those in their 40s, approximately 40% in those in their 50s, and approximately 60% in those in their 60s (Japanese Society for Sexual Medicine). However, in recent years, juvenile ED in those in their 20s and 30s has also been on the rise, with cases caused by psychogenic factors and pornography dependence becoming increasingly noticeable.

Self-Treatment for ED 1 | Exercise and Strength Training

ED improvement through exercise and strength training

Exercise is the method with the most evidence for self-improvement of ED. A 2018 meta-analysis (Gerbild et al., Sexual Medicine) reported that moderate aerobic exercise of more than 150 minutes per week showed a significant effect on ED improvement.

There are multiple mechanisms by which exercise works for ED.

  • Improvement of vascular endothelial function: Exercise promotes the production of nitric oxide (NO) and improves vasodilatory capacity
  • Increase in testosterone: In particular, resistance training (strength training) promotes testosterone secretion
  • Reduction of body fat percentage: Obesity causes excess estrogen and decreased testosterone, increasing ED risk
  • Improvement of mental health: Endorphin release from exercise reduces stress and anxiety

Effective Exercise Programs for ED Improvement

  • Aerobic exercise (more than 150 minutes per week): Walking, jogging, swimming, cycling, etc. Continue at an intensity that slightly raises your heart rate
  • Squats: Train large muscle groups in the lower body to promote testosterone secretion. Aim for 20 reps x 3 sets per day
  • Pelvic floor muscle training (Kegel exercises): Strengthen the bulbocavernosus (BC) muscle involved in maintaining erection. Hold for 5 seconds with the feeling of stopping urination midway, repeat 10 times, 3 sets per day
  • HIIT (High-Intensity Interval Training): Improves cardiopulmonary function in a short time, promoting testosterone secretion and NO production

Caution: Long-distance cycling (hard road biking for more than 3 hours per week) may conversely increase ED risk by compressing the perineum. Pay attention to saddle shape and position.

Self-Treatment for ED 2 | Foods and Dietary Improvement

Foods and dietary improvement that work for ED

“Foods that work for ED” is a topic many people search for, but just eating specific foods does not cure ED. However, by improving the overall diet, vascular function and hormonal balance can be regulated, which may lead to ED improvement.

In particular, the Mediterranean diet has been shown in multiple studies to be associated with ED improvement.

Nutrients and Foods Good for ED

Nutrient Expected Effect Foods Rich in It
Zinc Essential for testosterone synthesis Oysters, beef, pork liver, cheese
L-Citrulline Converted to L-arginine in the body, promotes NO production Watermelon, cucumber, melon
L-Arginine Precursor of nitric oxide (NO) Chicken, nuts, soy products
Omega-3 fatty acids Improvement of vascular endothelial function, anti-inflammatory Mackerel, salmon, sardines, flaxseed oil
Flavonoids Vasodilatory and antioxidant effects Berries, citrus fruits, dark chocolate
Vitamin D Maintenance of testosterone, vascular function Salmon, egg yolks, mushrooms

Conversely, there are also dietary habits to avoid. High-fat, high-sugar diets and excessive consumption of processed foods accelerate atherosclerosis and increase ED risk.

Self-Treatment for ED 3 | Smoking Cessation and Reduced Drinking

ED improvement through smoking cessation and reduced drinking

Smoking is one of the largest risk factors for ED. Nicotine and carbon monoxide contained in tobacco damage vascular endothelium and accelerate atherosclerosis of the penile arteries.

  • The ED risk for smokers is approximately twice that of non-smokers (meta-analysis: Cao et al., 2013)
  • ED improvement after smoking cessation: Vascular endothelial function begins to recover within several months to a year after smoking cessation, and improvement in erectile function has been reported
  • Heated tobacco products and e-cigarettes: The risk may be lower than conventional tobacco, but products containing nicotine still have vasoconstrictive effects, and complete smoking cessation is ideal for ED improvement

Regarding alcohol, small amounts (1-2 drinks per day) have no negative effect on ED due to vasodilatory and relaxation effects, but excessive drinking suppresses the central nervous system and reduces erectile function. Chronic heavy drinking also negatively affects testosterone metabolism via liver dysfunction.

Self-Treatment for ED 4 | Stress Management and Sleep

ED measures through stress management and improved sleep

In particular, in juvenile ED in those in their 20s and 30s, psychogenic factors account for a large proportion. Stress management and sufficient sleep are the basics of psychogenic ED improvement.

  • Performance anxiety: The pressure of “can I do it well” makes the sympathetic nervous system dominant, creating a vicious cycle that hinders erection
  • Stress from work and relationships: Chronic stress raises cortisol and lowers testosterone
  • Lack of sleep: Approximately 70% of testosterone is secreted during sleep. There are reports that men who sleep less than 5 hours have testosterone levels 10-15% lower

Specific countermeasures that are effective include the following.

  • Ensure 7-8 hours of quality sleep
  • Mindfulness meditation: 10 minutes of meditation per day is effective for reducing anxiety
  • Open communication with partner
  • Limiting pornography viewing: Excessive pornography dependence may dull sexual responses with actual partners

Are Supplements and Virility Products Effective?

ED improvement effects of supplements and virility products

Many people try supplements and virility products because they “do not want to rely on medication.” However, there is limited evidence that over-the-counter supplements and virility products have the same effect as ED medications.

Ingredient Expected Effect Evidence Level
Zinc supplements Improvement of testosterone in zinc deficiency Circle (effective only when there is deficiency)
Maca Improvement of libido and stamina Triangle (small-scale studies only)
L-Citrulline Promotion of NO production, vasodilation Triangle (reports of supplementary effect for mild ED)
Korean red ginseng Promotion of blood circulation, recovery from fatigue Triangle (improvement trends in some studies)
Over-the-counter virility products Mostly only nutritional support Cross (no effect equivalent to ED medications)

The biggest risk is overseas-made “powerful virility products.” Surveys by the Ministry of Health, Labour and Welfare have reported cases in which some overseas-made virility-enhancing supplements purchased online illegally contained unapproved pharmaceutical ingredients (sildenafil or tadalafil-like substances). These products carry a risk of health damage and should never be used.

Cautions and Limits of Self-Treatment for ED

Cautions and limits of self-treatment for ED

Lifestyle improvements are important as a foundation for ED measures, but relying solely on self-treatment also carries risks.

  • It takes time for effects to appear: The effects of lifestyle improvements often take several weeks to several months, with no immediate effect
  • Insufficient for moderate to severe ED: In the case of organic ED, lifestyle improvements alone often cannot achieve sufficient improvement
  • Possibility that ED is a sign of serious disease: ED can appear as an early symptom of atherosclerosis and may be a precursor to cardiovascular disease or diabetes
  • Worsening from neglect: Leaving ED untreated tends to fall into a vicious cycle of accumulated failure experiences leading to coexisting psychogenic ED and further worsening

We strongly recommend seeing a medical institution early in the following cases.

  • ED symptoms have continued for more than 3 months
  • Morning erections (nocturnal penile tumescence) have disappeared
  • You have a chronic illness such as diabetes, hypertension, or dyslipidemia
  • Accompanied by depressive symptoms or strong anxiety
  • It is affecting your relationship with your partner

ED Treatment at a Medical Institution as an Option

ED treatment at a medical institution

While trying self-improvement for ED, combining the use of PDE5 inhibitors (ED medications) can lead to more reliable and earlier improvement.

The 3 ED medications approved in Japan:

Drug Name Active Ingredient Duration of Effect Effect of Food Characteristics
Viagra sildenafil 4-6 hours Large Longest history with extensive clinical record
Levitra vardenafil 5-8 hours Somewhat large Highly fast-acting
Cialis tadalafil Up to 36 hours Almost none Long-lasting effect, daily dosing possible

The most effective approach is to combine ED medications with self-improvement. Supporting erectile function with medication while improving lifestyle and gradually reducing the dosage of medication – this is the basic strategy of modern ED treatment.

Frequently Asked Questions (FAQ)

Q. Can ED be treated on your own?

Mild ED or ED caused by lifestyle may improve with exercise, dietary improvement, smoking cessation, and stress management. However, for moderate or severe and organic ED, treatment at a medical institution is recommended.

Q. Are there foods that work for ED?

Foods rich in zinc such as oysters and beef, watermelon containing citrulline, antioxidant-rich berries and dark chocolate, and oily fish containing omega-3 fatty acids may have a positive effect through improved vascular function. However, food alone does not cure ED.

Q. Can strength training improve ED?

The combination of aerobic exercise and strength training is effective for improving ED. In particular, squats promote testosterone secretion, and pelvic floor muscle training (Kegel exercises) is said to be effective for improving the ability to maintain an erection.

Q. Can ED resolve on its own?

In the case of psychogenic ED, it may resolve on its own if the cause of stress or anxiety is removed. Temporary ED due to fatigue or alcohol also resolves. However, organic ED is unlikely to resolve on its own and tends to progress if left untreated.

Q. Can supplements or virility products cure ED?

There is no evidence that over-the-counter supplements or virility products have the same effect as ED medications. Some ingredients such as zinc and maca may have supplementary effects, but they are not the main pillar of ED treatment. Some overseas products have been found to contain unapproved ingredients, so caution is required.

Q. Do men in their 20s and 30s also get ED?

Yes. Juvenile ED is often caused by psychogenic factors (stress, pressure, relationship with a partner). In recent years, juvenile ED caused by pornography dependence has also been on the rise. ED in younger men tends to improve more easily when addressed early.

Q. What kinds of ED medications are there?

The 3 ED medications approved in Japan are Viagra (sildenafil), Levitra (vardenafil), and Cialis (tadalafil). They differ in duration of effect and the influence of food. Consult a doctor to choose the right one.

Summary

  • Exercise: Aerobic exercise of more than 150 minutes per week + pelvic floor muscle training has the most evidence
  • Diet: Based on the Mediterranean diet, consciously consume zinc, citrulline, and omega-3 fatty acids
  • Smoking cessation: The largest risk factor that approximately doubles ED risk. Vascular function recovers with smoking cessation
  • Stress and sleep: Especially in juvenile ED, resolving psychogenic factors is the key
  • Supplements: Stay in the supplementary role, not the main pillar of ED treatment
  • Limits: ED that is moderate or severe, lasts more than 3 months, or is accompanied by chronic illness should be seen at a medical institution

Self-improvement and treatment at a medical institution are not opposing approaches; combining them is most effective. For ED treatment consultations, please contact Mens Care Clinic. Online consultation available.
