Erectile dysfunction can be placed into several categories based on the cause:
Vascular erectile dysfunction is the most common type of erectile dysfunction. This is where the blood flow to the penis that’s needed to create and maintain an erection is affected by a vasculogenic condition such as cardiovascular disease or high blood pressure. Diabetes is also a common risk factor due to the effects on small vessels as well as the nerves.
Neurogenic erectile dysfunction occurs as a result of disruption with the nerves to the penis, which prevent signals from travelling from the brain to the penis to create an erection. This can be caused by pelvic surgery such as prostate operations, multiple sclerosis, Parkinson’s disease, a spinal injury or disorder, a stroke, radiation therapy or trauma.
Hormonal erectile dysfunction can occur as a result of hormonal conditions, such as hypogonadism which cause a reduction or increase in certain hormones including testosterone and cortisol.
Anatomical erectile dysfunction is where a condition, such as Peyronie’s disease, affects the tissue of the penis making it difficult to get an erection.
Psychogenic erectile dysfunction involves psychological conditions that affect your thoughts, feelings or behaviour, which can cause erectile dysfunction. Anxiety and depression are the most common psychological causes of erectile dysfunction, but your ability to get and maintain an erection may also be a result of relationship problems or being in a new relationship, a lack of sexual experience or knowledge, past sexual problems or sexual abuse.
Other factors that may affect your ability to get or maintain an erection include:
- Certain medications, such as diuretics, antidepressants and corticosteroids
- Excessive alcohol
- Illegal drug use, such as cannabis or cocaine
- Fatigue
- Obesity
- Sleep disorders
