Erectile Dysfunction or ED is a chronic condition characterized by the inability of a man to get a firm erection. The firmness of an erection is measured in terms of the patient being able to perform sexually and complete sexual intercourse. The degree of ED has to be determined by the doctor and can vary from the complete inability to achieve an erection to an erection that goes away too quickly. There are many things one can do to prevent or deal with erectile dysfunction. Quitting smoking, taking up some sports to get a certain amount of exercise regularly and losing excessive weight are all great ways to start. In general, the treatment depends on what has caused the problem.

Surprising as it may seem, for some patients the recommendation may be to modify the lifestyle, making it healthier. ED is usually treated with the help of drugs that increase the blood inflow into the tissue of the penis and with some sexual stimulation cause an erection that lasts long enough to have sex. The most efficient medicines include Viagra, Levitra and Cialis, each drug being efficient for different periods of time. For example, while Viagra will provide up to 4 hours of sexual performance, in case of Cialis it’s up to 36 hours, which is a lot more convenient.
