Understanding ED

ED Causes & Treatment Options

Understanding what causes erectile dysfunction is the first step to finding the right treatment. ED is very common, usually treatable, and can be a sign of other health issues worth addressing.

ED is Common and Treatable

Around 50% of men aged 40-70 experience some degree of ED. Most cases can be successfully treated with medication, lifestyle changes, or other therapies.

Physical Causes of ED

Physical causes account for the majority of ED cases, particularly in men over 40. Many are related to cardiovascular health.

Cardiovascular
  • Atherosclerosis (narrowed arteries)
  • High blood pressure
  • Heart disease
  • High cholesterol

ED can be an early warning sign of cardiovascular problems

Metabolic
  • Type 2 diabetes
  • Obesity
  • Metabolic syndrome

Diabetes is one of the most common causes of ED

Neurological
  • Multiple sclerosis
  • Parkinson's disease
  • Spinal cord injury
  • Stroke

Nerve damage can interfere with signals needed for erection

Hormonal
  • Low testosterone
  • Thyroid disorders
  • Hyperprolactinemia

Hormonal imbalances are less common but treatable causes

ED as a Warning Sign

ED can appear 3-5 years before other symptoms of cardiovascular disease. If you develop ED, especially if sudden or without obvious cause, it's worth having a cardiovascular health check.

Psychological Causes of ED

Psychological factors can cause ED on their own or make physical ED worse. They're particularly common in younger men.

Common Psychological Causes

  • • Performance anxiety
  • • Stress (work, financial, life events)
  • • Depression
  • • Anxiety disorders
  • • Relationship problems
  • • Low self-esteem or body image issues
  • • Previous negative sexual experiences

Signs ED May Be Psychological

  • • ED came on suddenly rather than gradually
  • • You can get erections during masturbation or morning erections
  • • ED occurs with one partner but not another
  • • ED is situational (e.g., only during intercourse)
  • • You're under significant stress
  • • You're younger with no obvious physical risk factors

Note: In practice, most ED has both physical and psychological components. Even when the initial cause is physical, anxiety about ED can make it worse. Treatment often addresses both.

Lifestyle Factors That Affect ED

These factors can cause or worsen ED - and importantly, addressing them can often improve erectile function significantly.

Smoking

Impact: Damages blood vessels and restricts blood flow

Good news: Quitting can improve erectile function within weeks to months

Excessive Alcohol

Impact: Depresses nervous system and affects hormone levels

Good news: Reducing alcohol often leads to noticeable improvement

Obesity

Impact: Associated with cardiovascular issues, diabetes, and low testosterone

Good news: Weight loss can significantly improve erectile function

Sedentary Lifestyle

Impact: Poor cardiovascular fitness affects blood flow

Good news: Regular exercise improves both ED and overall health

When to See a Doctor

While occasional erectile difficulties are normal, you should consider seeing a doctor if:

  • ED is persistent (happening more than 50% of the time)
  • ED came on suddenly without obvious cause
  • You have risk factors for cardiovascular disease
  • ED is causing relationship problems or distress
  • You want to rule out underlying health conditions

Don't be embarrassed: Doctors deal with ED regularly. It's a medical issue like any other. Getting proper assessment ensures you get the right treatment and identifies any underlying health issues.
