Medically reviewed by C. Fookes, BPharm Last updated on Jun 11, Erection problems are common and an occasional problem achieving an erection is normal. Erectile dysfunction ED is the consistent inability to get or maintain an erection that is firm enough to have sexual intercourse. Men with ED are either unable to get an erection at all, achieve an erection inconsistently, or achieve an erection briefly but not long enough for intercourse. Erectile dysfunction may also be called impotence.
April 18, by PCRI. Before discussing recovery of erectile function in men following radical prostatectomy, it is important to understand the current causes and treatments for ED. There are many causes of ED. Diabetics are four times more likely to have ED because they tend to have poor blood flow and nerve function in their penis. Radical prostatectomy can result in nerve injury to the penis. Unfortunately, some men never recover their erections after surgery. Other causes of ED include smoking, high blood pressure, high cholesterol, and certain medications.
Getting and maintaining an erection requires a surprising amount of things to go right. You have to get aroused, then pass that signal from your brain, through your nerves and hormones, to your blood vessels and muscles before an erection can even happen. If one thing goes wrong in that complicated exchange between your cardiovascular, and nerve system, and your hormone levels, blood vessels, and even your mood the result is usually erectile dysfunction. In other words, getting an erection is hard. Even better, many of these ED causes are treatable with medication and simple lifestyle changes.
The aim of this study was to determine the functional and morphologic effects of nebivolol on penile structures in hypertensive rats. After 6 months, SHR groups given nebivolol and amlodipine showed similar reductions in blood pressure compared with untreated SHR. Nebivolol presented equivalent BP control compared with amlodipine. However, only nebivolol showed a significant better functional outcome with a protective role against structural changes in erectile tissue that are caused by arterial hypertension.
