Control. Stamina. Confidence.

Erectile dysfunction (ED), also known as impotence, occurs when a man is unable to achieve or maintain an erection that is firm enough for sexual activity consistently. While many men may have occasional nights of difficulty, this is normal. If erectile dysfunction occurs for longer than three months and consistently affects a man's ability to engage in sexual activity, it is considered a clinical problem.

ED does not just affect a man in the bedroom, it could potentially be a symptom of a more serious condition, such as heart disease or diabetes, long before other symptoms appear. This makes it very important for men to receive proper evaluation and treatment.

Key Points: ED is a common and treatable condition, and it may be the first indication of a problem impacting a man's general health.

Erectile dysfunction is rarely caused by one thing alone. For men, erectile dysfunction usually results from a combination of several factors, including physical, psychological and lifestyle factors.

Physical Causes Of Erectile Dysfunction

Physical causes of ED are those that affect the blood supply, nerve supply or hormones required to achieve and maintain an erection. Some common physical causes of erectile dysfunction are:

• Cardiac conditions and atherosclerosis (narrowing of the arteries due to the build-up of plaque)
• Type 2 diabetes (affects circulation, nerve function)
• Hypertension (high blood pressure)
• Hyperlipidemia (high cholesterol)
• Obesity/metabolic syndrome
• Hormonal imbalances (Low testosterone, thyroid disorders & excess cortisol)
• Neurological disorders (Parkinson's disease, spinal injury, Alzheimer's disease)
• Prostate disease or side effects from chemotherapy for prostate cancer
• Peyronie's disease, scar tissue in the penis causing curvature and/or pain
• Certain drugs (antidepressants, blood pressure drugs and cholesterol lowering drugs)

Psychological Causes

The connection between mental health and sexual performance is strong. The majority of men experiencing ED due to psychological causes are not only younger but also have experienced these issues since they were younger. Some psychological causes include:

• Performance anxiety occurs most frequently with new partners
• Depression/chronic stress
• Low self-esteem and/or body image
• Difficulty in relationships/resolving emotional conflict
• Negative past sexual experiences.

Lifestyle Factors

• Smoking causes permanent damage to the blood vessels that supply blood to the penis
• Excessive alcohol intake
• Having a sedentary lifestyle or not engaging in physical activity
• Consuming an inadequate amount of fruits/vegetables
• Lack of quality sleep/having sleep problems.

Modern erectile dysfunction treatment is highly effective and for most of the men, the right treatment or combination of treatments can restore their confidence and sexual function. There are several treatment options available for erectile dysfunction, which include the following:

Treatment Options at a Glance

Oral Medications (Sildenafil, Tadalafil, Avanafil)

How It Works: Relax blood vessels in the penis, increasing blood flow with sexual stimulation

Best For: Most men with ED — first-line treatment

Daily Low-Dose Tablet (Tadalafil 2.5-5mg)

How It Works: Builds a steady drug level so you're always ready, no timing needed

Best For: Men who prefer spontaneity

Penile Injection Therapy (Alprostadil)

How It Works: Injected into the penis before intercourse, causes a direct erection

Best For: Men unresponsive to oral medication

Vacuum Erection Device (Penis Pump)

How It Works: Creates a vacuum to draw blood into the penis; the ring maintains an erection

Best For: Men who cannot take oral medications

Penile Implant (Surgery)

How It Works: Inflatable or semirigid device surgically inserted into the penis

Best For: Severe ED after other treatments fail

Psychological Therapy (CBT / Sex Therapy)

How It Works: Addresses anxiety, depression, relationship issues contributing to ED

Best For: Psychological or mixed-cause ED, especially in younger men

Testosterone Replacement Therapy (TRT)

How It Works: Restores hormone levels when low testosterone is contributing to ED

Best For: Men with confirmed hypogonadism (low testosterone)

Low-Intensity Shockwave Therapy (LiSWT)

How It Works: Sound waves stimulate new blood vessel growth in penile tissue

Best For: Emerging option; still under clinical evaluation in Australia

Lifestyle Changes

How It Works: Quitting smoking, exercising, losing weight, improving diet

Best For: All men, often combined with medical treatment

1. Oral Medications (PDE5 Inhibitors)

PDE5 Inhibitors, found in oral medications, are the most commonly used first-line treatment for erectile dysfunction in Australia. PDE5 inhibitors will relax smooth muscles allowing for increased blood to flow into the penis facilitating erections when sexual arousal occurs. This class of medications will not induce an erection without sexual arousal being present.

• Sildenafil (Viagra): dm Ready
  • Onset Time: 30 to 60 minutes
  • Duration: 4 to 6 hours
  • Best For: On-demand and occasional use
• Tadalafil (Cialis): dm Lasting
  • Onset Time: 30 to 60 minutes
  • Duration: Up to 36 hours
  • Best For: Weekend plans and longer activity window
• Tadalafil (Low Dose): dm Steady
  • Onset Time: Taken daily
  • Duration: Always-on effect
  • Best For: Spontaneous intimacy without planning
• Vardenafil (Brand Name: Levitra)
  • Onset Time: 25 to 60 minutes
  • Duration: 4 to 5 hours
  • Best For: Diabetes patients and older men
• Avanafil (Brand Name: Spedra / Stendra)
  • Onset Time: 15 to 30 minutes
  • Duration: 4 to 6 hours
  • Best For: Fast action with fewer side effects

Important: Never take PDE5 inhibiting medications with nitrate containing medications (used to treat chest pain). Taking these medications together can cause dangerously decreased blood pressure. Always check with a physician before taking any medications to treat erectile dysfunction.

2. Erectile Dysfunction Alternative Treatments

For men with erectile dysfunction that cannot tolerate or respond to PDE5 inhibiting medications, there are alternative treatment options to consider:

Penile Injection Therapy (Alprostadil)

When a man injects alprostadil directly into the side of the penis with a very thin needle, he can expect to achieve an erection within 5 to 20 minutes of injection, with the erection generally lasting for at least one hour. As part of the process, physicians will train men how to safely inject their own alprostadil at home for future use.

Intraurethral Medicine (MUSE)

With the use of special applicators, alprostadil is inserted in the female urethra via a small pellet. Men can expect an erection to develop within 10 minutes of inserting an intraurethral medication pellet, with the erection typically lasting between 30 and 60 minutes.

Vacuum Erection Device (Penis Pump)

An apparatus is applied to the penis that uses a manual or electrical means to create a vacuum, which subsequently brings blood into the erectile tissues. Finally, a tension band is applied to maintain the erection. The process is drug free and appropriate for those with medical restrictions.

Penile Implant (Surgical)

This option involves surgery to insert either an inflatable or semi rigid and permanent system into the shaft of the penis. This type of device is used on patients who have not had success with treatment options available. Patient satisfaction rates after surgery are very high.

Low-Intensity Shockwave Therapy (LiSWT)

This newer technology is still under investigation but involves using directed sound waves to enhance tissue in the penis and create new blood vessels. As an experimental measure in Australia, clinical trials are currently underway and results from those studies will dictate whether or not LiSWT is available in the future.

ED natural treatments have the potential to drastically reduce an individual’s ability to have an erection, particularly when ED is mild-moderate. Some men regain the use of their erections through changes to their lifestyles by themselves only.

Quit Smoking

• Evidence Level: Strong

Regular Exercise

• Why It Helps ED: Improves cardiovascular health, boosts testosterone and reduces anxiety
• Evidence Level: Strong

Healthy Weight Management

• Why It Helps ED: Obesity reduces testosterone and impairs vascular function
• Evidence Level: Strong

Mediterranean / Heart Healthy Diet

• Why It Helps ED: JAMA study links plant rich diets to reduced ED risk in men
• Evidence Level: Moderate

Reduce Alcohol Intake

• Why It Helps ED: Chronic heavy drinking suppresses testosterone and impairs nerve signals
• Evidence Level: Moderate

Improve Sleep Quality

• Why It Helps ED: Poor sleep reduces testosterone and treats sleep apnoea-related ED
• Evidence Level: Moderate

Stress Reduction / Mindfulness

• Why It Helps ED: Reduces cortisol which directly suppresses testosterone production
• Evidence Level: Moderate

Psychological & Counselling Treatments for ED

In general terms people with physical & lifestyle causes of ED who have developed anxiety about their performance will have their underlying causes of ED addressed through therapy. The potential outcomes produced through addressing the mental layer of ED often yield better results than medications.

• Cognitive Behavioural Therapy (CBT) is designed to shift negative views about sex and performance.
• Sex Therapy provides a distinct form of therapy that is aimed at improving your sexual function (where possible) through communication skills and will give you direction for improving your relationship with your partner.
• Couples counseling is about providing support for both partners in a relationship and assisting with rebuilding intimacy.
• Mindfulness based therapy consists of present-focused awareness which can significantly diminish any performance fears.

If your GP or psychiatrist believes you may benefit from this form of therapy, they can refer you to a psychologist, a GP-based mental health professional or a trained sex therapist. The use of a combination of medications and therapies can have the best overall benefit for your well-being.

Can ED Affect Younger Men?

Yes, erectile dysfunction (ED) is indeed something that can affect men of all ages, not just older men. Research shows that men at any age have ED, including younger men under forty years old. Most of the time in young men, their ED is caused by something psychological like performance anxiety, stress, depression, or relationship problems, not necessarily something physical.

That said, lifestyle issues like drinking alcohol, smoking, eating poorly, and not exercising can also lead to erectile dysfunction in men in their twenties and thirties. Getting a full assessment from a medical professional will help identify what is causing the ED so that the proper treatment can be applied.

ED as a Warning Sign: The Heart-Penis Connection

The arteries that provide blood flow to the penis are smaller than the arteries providing blood flow to the heart, which means that men who have ED may have an early warning sign for cardiovascular disease; ED can develop long before a physician would have the opportunity to test for cardiovascular disease (up to 3 to 5 years) and possibly experience a heart attack or stroke.

• Men with erectile dysfunction are approximately two times for likely to develop cardiovascular disease as compared to men without erectile dysfunction
• Erectile dysfunction can be symptomatic of cardiovascular risk factors such as hypertension, diabetes, and high cholesterol.
• Treating the cardiovascular risk factors that cause erectile dysfunction can improve both the man's heart health (reduce their risk of heart attack/stroke) as well as their ability to achieve an erection.

This is why the doctors at Directmeds do not simply prescribe a pill, they assess the total health picture of the patient to help identify and address any risk factors first.

The success of treating erectile dysfunction is dependent on the cause of ED, your general health and the treatment pursued. Here’s a realistic assessment of what you can expect:

• 70%-80% of men will respond positively to oral medication for ED
• Most will respond to their first few doses, but some men will require new adjustments to their dose
• Most psychological counseling will result in improvement after 6-12 weeks
• Changes in lifestyle will create considerable benefits after 3-6 months
• Men who have penile implants as a last resort report a satisfaction rate of over 90%

There are times that ED will be manageable but not curable but satisfactory sexual function can be achieved with treatment. The most important factor is not to stop looking for the best method of treatment after the first attempt. Many men ultimately find an adequate treatment through a continuous process of treatment trial and error with the help of their doctor.
