What causes erectile failure

Erection failure is sexual dysfunction that is characterised by inability to attain or maintain erection that is firm enough. All men can occasionally face the problem, but it is a cause of concern when it happens often.


Erection failure is often mistaken to be caused only due to physiological issues. However, mental problems are seen to be main reasons of erection failure in most of the cases. It can be either due to performance anxiety i.e. if a man feels that he is forced to perform well then he may become anxious. Sexually demanding situations can bring in occasional difficulty in erection.

Neurological disorders

The neurological disorders that inhibit electrical nerve to the penis can cause erection failure. For example, stroke and spinal cord injury are some of the disorders that can lead to erection failure.

Blood flow

Erection failure can also result from impeded blood flow. Vascular diseases can block or constrain blood arteries of penis. Besides this vascular diseases also slow down the blood supply to the penis that can finally lead to erectile dysfunction.

Hormonal imbalance

Hormonal imbalance in men occurs due to psychological reasons rather than physiological. In some cases, pituitary glands may fail to produce the stimulating hormones that encourage erection. Lack of interest in sex and erectile dysfunction are also caused by failure of production of thyroid and adrenal gland. This hormonal deficiency can be corrected by injecting hormones.


Priapism is a painful medical condition in which erected penis does not return to normal condition in spite of physical and psychological stimulation. If your erection lasts for long or unusual period then you must take immediate medical assistance.


Erectile failure is closely associated with high blood sugar level. When the blood sugar level is lowered then there will be improvement in erection.

Penis Infection

Infection in penis and the surrounding tissues can lead to erection failure in men. Viral infection in testes can cause discomfort and lead to erectile failure. Bacterial infection can inflame urethra and prostate glands finally leading to pain in genital area.
