Erectile Dysfunction Causes

There are various causes of ED – it can be physical (a ‘hardware’ problem) or psychological (mental health effects – ‘the software’). In order for sexual activity to be physically and mentally satisfactory, both physical and mental health should be considered.


Besides this however, biological processes also need to be at their optimum – as essentially, these processes are what make up the sexual response cycle.


For an individual to have a healthy and sustainable erection, three aspects of the body’s process should be working well.


  1. The blood flow (BF) or blood supply
  2. Nerve supply and blood vessel health
  3. The balance of sex hormones


Problems and/or disruptions in any of these processes can lead to ED

How Common Is Erectile Dysfunction?

It has been said that said that one in 10 adult males experience ED on a long-term basis. Besides popular belief, ED is not only common in older ages, rather affects younger men as well. It has been researched that not being able to achieve an erection at least 50% of the time generally correlates to an ED diagnosis.

Understanding how sexual dysfunction can affect sexual performance is key. With this in mind, there are various factors that can lead to Erectile Dysfunction symptoms. Breaking them down into different possibilities allows you to get a clearer picture on the different types of situations that can lead to ED symptoms.

Sexual and medical history is important to diagnose and treat erectile dysfunction – but determine the right cause, is a key as well. Here are the most common causes of ED broken down into sections that can make it easy to understand.

Physical Causes of Erectile Dysfunction

Two Doctors explaining about the Physical Causes of Erectile Dysfunction

Medical Conditions

Health conditions such as peripheral artery disease, coronary artery disease (any heart or cardiovascular disease), atherosclerosis, diabetes (increased blood sugar), hypertension (high blood pressure), obesity (due to lack of physical activity for example), etc, can cause reduced blood flow to the penis due to artery narrowing. This can affect sexual function and activity as this can lead to sexual dysfunction. In fact, ED can lead to other sexual disorders such as low sexual desire.

Furthermore, spinal cord injury or radiation therapy can disrupt or harm nerves present in the penis.

Nerve-damaging pelvic injury


Physical injury to the pelvic area can damage pelvic nerves which can reduce flow to the pelvic area. Optimum blood flow is required for a sustainable erection – damage to this area can lead to negative effects to erectile function.


Surgeries – such as prostate surgery, or any surgery in the pelvic region – has a risk of affecting the pelvic nerves. In some cases, therefore, any injury to this area through reproductive surgery can result in damaged pelvic nerves or decrease blood supply to penile arteries.

Hormonal disruption


Sex hormones – testosterone (androgens), estrogen and progesterone – play a critical role in sexual health. The abnormal variations of these hormone levels – through increased production or suppression – can result in concerns with erectile function.

  • Increased or decreased testosterone production
  • Increased prolactin production
  • Increased steroid usage causes testosterone suppression
  • Increased or decreased thyroid hormone production.
  • Increased growth hormone production
  • Penis abnormalities
  • Phimosis/Paraphimosis
  • Peyronie’s disease

Men with low sexual desire such as in Hypoactive Sexual Desire Disorder (HSDD) can also present with arousal concerns such as ED.

Psychological Causes of Erectile Dysfunction

Psychological Causes of Erectile Dysfunction

The smooth working of physical hardware or genitalia isn’t the only thing needed for sex to be satisfying and comfortable. The mind and body, together, affect the sexual arousal phases.

  • Anxiety and/or anxiety disorders such as OCD
  • Depression
  • Chronic stress: Stress hormones cortisol and adrenaline cause sex hormone suppression
  • Performance Anxiety
  • Interpersonal concerns among couples
  • Abuse

Can Addictions Cause Erectile Dysfunction?

Recreational drug usage can affect an individual’s ability to get and sustain an erection especially when people abuse them or are addicted to them in the following mechanisms.


  1. Alcohol: causes dehydration (reduces sensation in genitals), lowers testosterone (lowers sexual desire) levels, and is a depressant (suppresses blood circulation and nerve sensitivity).
  2. Nicotine: Disrupts blood circulation and has negative effects on the arousal phase of the sexual response cycle.
  3. Cannabis: Can prevent smooth muscle relaxation needed for penis blood flow and erection.
  4. Cocaine: Post-effects of the drug can cause delayed ejaculation, can lower sperm count, and can cause ED.
  5. Porn addiction can also be a cause of ED due to the stimuli’ desensitization.

What Medications Could Cause Erectile Dysfunction?

There are a variety of prescription medication classes that can result in ED as a negative side effect. These classes of intravenous or oral prescription drugs treat the following conditions.


  1. Hypertension drugs: some of these can negatively affect penis blood flow
  2. Cholesterol drugs (specifically some of the Statins): can lower testosterone levels
  3. Psychiatric drugs: some medications in some people can disrupt brain chemical signaling which affects sexual function
  4. Chemotherapy: can cause nervous system damage
  5. Cardiovascular drugs: can cause low testosterone production in some patients
  6. Pain killers: Opioids can reduce testosterone levels in some patients

Is medication induced erectile dysfunction permanent?
