Fortunately, most cases of sexual dysfunction are treatable, so it is important to share your concerns with your partner and doctor. 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. Pelvic floor muscle exercises - The pelvic floor muscles are a group of muscles that wrap around the underside of the bladder and rectum. One of these muscles (the bulbocavernosus muscle) also partly wraps around the base of the penis. This is involved with preventing blood escaping during an erection, (as well as being active during ejaculation, and when emptying the urethra of urine when finishing at the toilet). buy propecia pills propecia online cheapest generic cialis online buy cialis In all four studies, vardenafil was significantly better than placebo in improving men's ability to achieve and maintain erections in all age categories (less than 45, 45-65, and greater than 65 years of age) and in all races. Erectile Dysfunction At A Glance: Erectile dysfunction is treatable in all age groups. Erectile dysfunction (impotence) occurs when a man can no longer get or keep an erection firm enough for sexual intercourse. Having erection trouble from time to time isn't necessarily a cause for concern. But if erectile dysfunction is an ongoing problem, it may cause stress, cause relationship problems or affect your self-confidence. 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).
