If a man is unable to sustain an erection or maintain an erection for a sufficient period of time, he is considered impotent. Impotence refers to erectile dysfunction, which means that a man is unable to sustain an erection during sexual intercourse or is unable to maintain an erection for a sufficient period of time after erection to accomplish a satisfactory sexual life. Impotence is a chronic disease that affects both physical and mental health. It may be caused by psychological reasons, such as excessive mental stress, disharmonious relationship between husband and wife, excessive economic pressure, and fearfulness. It may also be caused by organic diseases, such as vascular diseases, neurological diseases, and diseases of the penis itself. Impotence can seriously affect the couple’s life, once found to the hospital in a timely manner after the consultation, with the doctor before going to the examination and treatment.
