How common is erectile dysfunction - Erectile dysfunction (ED, impotence) varies in severity; some men have a total inability to achieve an erection, others have an inconsistent ability to achieve an erection, and still others can sustain only brief erections. The variations in severity of erectile dysfunction make estimating its frequency difficult. Many men also are reluctant to discuss erectile dysfunction with their doctors due to embarrassment, and thus the condition is underdiagnosed. Nevertheless, experts have estimated that erectile dysfunction affects 30 million men in the United States. buy levitra for sale online viagra switzerland online buy viagra online
Surgery: There are different types of surgery. Implanted devices, known as prostheses, can restore erection in many men. These can come in different forms. For instance, paired rods can be inserted into the corpora cavernosa to enable the user to manually adjust the position of the penis. Alternatively, inflatable cylinders can be inserted inside the penis and expanded using pressurized fluid. In some cases doctors may attempt to repair blockages in damaged arteries. However, this usually only works if the blockages are not widespread. cialis generic order online bad experience buy cialis

Vacuum devices - There are several different devices. Basically, you put your penis into a plastic container. A pump then sucks out the air from the container to create a vacuum. This causes blood to be drawn into the penis and cause an erection. When erect, a rubber band is placed at the base of the penis to maintain the erection. The plastic container is then taken off the penis and the penis remains erect until the rubber band is removed (which must be removed within 30 minutes). Therefore, the dose and frequency of tadalafil has to be lowered in the following examples:Medications such as erythromycin, ketoconazole (Nizoral), itraconazole (Sporanox), ritonavir (Norvir), and indinavir (Crixivan) can slow the breakdown of tadalafil. Therefore men taking these medications should not take more than 10 mg of tadalafil and should not take tadalafil more frequently than every 72 hours. buy levitra for sale online buy levitra for sale online Men with a rare heart condition known as long QT syndrome should not take vardenafil since this may lead to abnormal heart rhythms. The QT interval is the time it takes for the heart's muscle to recover after it has contracted. The QT interval is measured with an electrocardiogram (EKG). Some people have longer than normal QT intervals, and they may develop potentially life-threatening abnormal heart rhythms, especially when given certain medications. Since long QT syndrome can be inherited, men with a family history of long QT syndrome should not take vardenafil. Furthermore, vardenafil is not recommended for men who are taking medications that can affect the QT interval such as quinidine (Quinaglute, Quinidex), procainamide (Pronestyl; Procan-SR; Procanbid), amiodarone (Cordarone), and sotalol (Betapace). The risk of heart attack or abnormal heart rhythms during sex is higher in men with unstable angina (angina that occurs at rest or with minimal exertion), poorly controlled hypertension, moderate to severe heart failure, moderate to severe disease of the heart valves, recent heart attack (less than two weeks previously), potentially life-threatening disorders of heart rhythm such as recurrent ventricular tachycardia, and moderate to severe disease of the heart muscles. In these men, doctors usually stabilize or treat the heart conditions before prescribing sildenafil.
