Health problems such as heart disease and vascular problems can raise the risk of erectile dysfunction. Experts also believe that psychological factors can do the same. According to research, stress, anxiety, guilt, depression, low self-esteem, and fear of sexual failure cause 10% to 20% of ED cases.
Men with a physical cause for ED frequently experience the same sort of psychological reactions such as stress, anxiety, guilt, depression. The other surprising causes are smoking. Smoking affects blood flow in veins and arteries, and hormonal abnormalities, such as not enough testosterone which can lead to ED. If you notice any problems, the first thing to do is quit smoking and talk to your doctor.
