ED can feel like it hits out of nowhere. But often, there’s a reason behind it, and sometimes it is more than one. Understanding what causes erectile dysfunction is the first step in taking back control of your sexual health.

AnswerBox: Erectile dysfunction can be caused by physical health issues like heart disease or diabetes, psychological factors like stress or anxiety, or a combination of both.


What Is Erectile Dysfunction, Really?

Erectile dysfunction (ED) refers to the consistent inability to achieve or maintain an erection sufficient for satisfactory sexual performance. It’s a medical condition that affects confidence, emotional wellbeing, and intimate relationships [1].

In Australia, it is not uncommon to have Erectile Dysfunction and the percentage increases with age [1].

Common Physical Causes of ED

The majority of ED cases are linked to underlying physical health conditions that impact blood flow, nerve function, or hormone levels. Scientifically supported causes include:

·      Cardiovascular disease: Atherosclerosis can reduce arterial blood flow to the penis, impairing erectile response [1].

·      Diabetes mellitus: Both type 1 and type 2 diabetes are strongly associated with ED due to vascular and neurological damage [1][3].

·      Hypertension and high cholesterol: These contribute to endothelial dysfunction, which impairs blood vessel dilation necessary for erections [1].

·      Obesity: Excess adipose tissue can lead to hormonal imbalances and increased risk of metabolic syndrome [3].

·      Prostate cancer treatment: Surgical and radiotherapy interventions often damage the nerves or blood supply to the penis [1][4].

·      Neurological disorders: Conditions like Parkinson’s disease, multiple sclerosis, and stroke are all documented ED risk factors [3].

·      Medication side effects: Common offenders include selective serotonin reuptake inhibitors (SSRIs) and antihypertensives [5].

Psychological and Behavioural Factors

Mental health and sexual performance are tightly linked. Psychological causes are especially prevalent in younger men and may either be primary or secondary to physical ED.

·      Stress and performance anxiety can disrupt the brain-penis connection essential for initiating erections [2][5].

·      Depression is often accompanied by reduced libido and impaired arousal [1].

·      Relationship difficulties or traumatic experiences may result in sexual dysfunction.

·      Porn-induced ED, though still debated, is gaining recognition for contributing to desensitisation and altered arousal responses.

ED in Younger Men: A Growing Concern

While ED is commonly seen as an age related condition, recent data show a rising prevalence among men under 40. Contributing factors include:

·      High psychological stress related to work, study, finances or relationships [2]

·      Early exposure to internet pornography and unrealistic expectations

·      Illicit drug and alcohol use, especially substances that impair central nervous system function

·      Lack of sleep and sedentary lifestyle

Research published in the Medical Journal of Australia emphasises that early ED in young men may be a “canary in the coal mine” for broader psychological or metabolic concerns [5].

When to Seek Medical Advice

ED can be a symptom of serious underlying health problems. According to Healthy Male, men experiencing persistent ED should seek medical assessment not only to improve sexual function but to identify potentially life threatening conditions like cardiovascular disease [1][6].
