Erectile dysfunction (ED) is one of the most common health concerns among men, yet it is still surrounded by myths. Understanding what drives it is the first step toward addressing it with confidence.

What causes erectile dysfunction?

ED usually results from a mix of physical and psychological factors. Blood flow, nerve signalling, hormones and mental state all play a role.

Physical factors

  • Cardiovascular conditions that reduce blood flow
  • Diabetes and high blood pressure
  • Certain medications and smoking

Psychological factors

Stress, anxiety and relationship pressures can all contribute, often alongside physical causes.

Treatment options

Most men respond well to oral medication such as sildenafil or tadalafil, combined with lifestyle changes. Your doctor can help you choose a suitable option.

ED is a signal worth listening to — it can be an early marker of wider cardiovascular health.

Key Takeaways

  • ED is common and, in most cases, highly treatable.
  • It often has both physical and psychological causes.
  • Oral medication plus lifestyle changes works for most men.
  • ED can be an early sign of cardiovascular issues — worth a check-up.
