There are seven main causes which increase the risk of experiencing erection difficulties.
Pyschological causes. Conditions such as anxiety, depression and even stress can affect sexuality. Another potential cause is excessive worrying about relationship, employment or family problems which can lead to a neglected sex life. Fatigue, poor appetite, lack of exercise, insomnia or a failure can also affect your sexual reflexes.
Vascular causes. The artery supplying the penis with blood is prone to the same vascular risk factors as any other blood vessel in the body. Therefore the most frequent causes of vascular impotence are diabetes, high blood pressure, increased cholesterol, smoking and cardiovascular diseases. Prostate, bladder or rectal surgery, or radiotherapy in the area around the pelvis can also damage these vessels and generate erection problems.
Pharmacological causes. There are several medicinal products whose secondary effects may include a decreased ability to sustain an erection. Featured among those products are medicines used to treat high blood pressure, heart disease and psychiatric conditions.
Neurological erectile dysfunction arises when the brain experiences difficulties in transmitting messages down the spinal cord to the penis. This is often caused by spinal cord injuries, multiple sclerosis, diabetes, kidney failure or due to surgery in the pelvic region. Neurological impotence is also caused by chronic kidney failure.
Hormonal causes. Hormonal imbalances, such as a testosterone deficiency, elevated prolactin levels or abnormal thyroid levels, can be a cause of erectile dysfunction.
Anatomical or structural causes. Male reproductive system anomalies (e.g., hypospadias or epispadias), micropenis, congenital penile curvature, Peyronie’s disease.
