Physical causes of erectile dysfunction

Cardiovascular conditions

An umbrella term for a group of conditions that affect the function of the heart and, more crucially in the case of ED, circulation.

These conditions cause blood flow to be restricted to many of your vital organs, including your heart and brain. It puts you at a higher risk of serious cardiovascular events (heart attack or stroke) but can also cause ED.

This is because, like the rest of the body, blood flow is restricted to the penis. The penis needs adequate blood flow to the arteries and blood vessels to become hard, so when you have a vascular condition, you have a higher risk of ED.

Cardiovascular conditions that are ED risk factors include:

   high cholesterol
   high blood pressure (hypertension)
   atherosclerosis (clogged blood vessels)
   coronary artery disease

Diabetes

Diabetes , specifically type 2 diabetes, is another leading cause of ED . In fact, studies have estimated that 50% of men diagnosed with type 2 diabetes will develop ED within 5 to 10 years of diagnosis.

Diabetes is an endocrine disease that develops when the blood sugar level is too high. Over time and without intervention, this can damage the blood vessels. Similar to cardiovascular conditions, this can restrict blood flow to the penis.

Poorly controlled blood sugar levels also cause nerve damage, a phenomenon known as diabetic neuropathy. Although this usually occurs in the legs and feet, it can also be linked to impotence in men.

Neurological disorders

Impotence can also be a complication of neurological disorders, sometimes referred to as neurogenic ED. There are  비아그라  can happen.

The first is that these disorders can interfere with the processing of sexual stimuli, which affects your sex drive and means that it can be harder to get excited.

The second reason is that they also interfere with the physical process, as these conditions can interfere with the neural pathways between the spinal cord (central nervous system) and the pelvic nerves. The pelvic nerves are responsible for orgasm, ejaculation and erectile function.

Examples of neurological disorders that cause ED include:

   multiple sclerosis (MS)
   Parkinson's disease
   multiple system atrophy (MSA)
   spinal cord injury
   Alzheimer's disease
   epilepsy and other conditions that cause seizures

Although there are few studies on the effect of the nervous system on sexual dysfunction, one study found that nearly 40% of men with a neurological disorder had ED, half of whom had moderate to severe ED.
