Causes of Erectile Dysfunction

Erectile dysfunction (ED) can have various causes, such as:

  • disease;
  • certain medicines intake;
  • psychological problems related to stress.

To better understand the possible causes of erectile dysfunction, you need to understand what determines the erection.

When a man is sexually excited, his brain sends signals to the nerves. Nerves stimulate blood flow to penis, because of this tissue expands and hardens. So anything that interferes with nervous system performance or blood circulation, can cause problems with potency.

Anything that affects libido (sexual desire and excitement), can also cause impotence, because of decreased libido brain harder controls erection. Mental disorders such as depression can decrease libido, as well as hormone levels (chemical substances produced by the body).

There are four main types of physical disorders that prevent erection emergence:

  • vasculogenic disorders are blood flow disorders to penis;
  • neurogenic disorders are disorders of nervous system comprising brain, nerves, and spinal cord;
  • hormonal disorders are hormonal violations;
  • anatomical disorders are disorders of penis anatomical structure.

Vasculogenic disorders:

  • Cardiovascular disease – the disease of cardiac or blood vessels, such as arteriosclerosis (arteries hardening);
  • high blood pressure (hypertension);
  • diabetes – a disease associated with elevated levels of glucose in blood can affect both blood supply and nerve endings in penis; it is also known as neurogenic disorder.

Erectile dysfunction has a direct relationship with cardiovascular disease, so it may be one of the first reasons that would consider the doctor for diagnosis and initial erectile dysfunction treatment.
