- Diabetes – Causes nerve and artery damage which can make achieving an erection difficult.
- Kidney Disease – Causes chemical and hormonal changes which often lead to lower libido and sexual performance.
- Neurological Diseases – Damage to the normal functioning of the nerves and brain make it difficult to achieve and maintain an erection. Common examples include strokes, multiple sclerosis (MS), Alzheimer’s, and Parkinson’s disease.
- Vascular Disease – Account for up to 70% of all diagnosed ED cases due to restrictions in blood flow to the heart, brain, and penis.
Non-disease related causes of ED:
- Prostate or Bladder Surgery – damage or removal of nerves and tissue in the pelvic region can often cause physical desensitization in men.
- Injuries – Physical injuries to the pelvis, lower spinal column, bladder, and penis can cause long-term blood flow or sensitivity problems.
- Hormonal Imbalances – Often associated with andropause in middle-aged men, imbalances of the thyroid, prolactin, and testosterone can all negatively impact a man’s sexual virility.
- Venous Leak – Occurs when the veins in the penis are physically unable to stop the blood from flowing back out of the penis, making an erection impossible.
- Tobacco, Alcohol, or Drug Use – These substances have been clinically proven to damage blood vessels and restrict blood flow throughout the body, ultimately leading to erectile dysfunction.
- Prescription Drugs – Over 200 types of prescription drugs are known to cause ED.
- Prostate Enlargement – Recently implicated as being associated with ED, enlarged prostates may be causing restrictions in nerve and blood vessel function.
