What is erectile dysfunction?

Erectile dysfunction is described as the inability to achieve an erection firm enough for sexual intercourse, or alternatively, the inability to sustain an erection long enough to achieve climax. While this is a troubling and unpleasant condition for many men, it is almost always the symptom or result of another underlying problem and can be caused by a number of factors. The following are common causes of erectile dysfunction.


There are a number of surgeries which may result in short or long term erectile dysfunction. Surgery such as cystectomy and prostatectomy can disrupt the nerves and cause erectile dysfunction. Over recent years, robotic surgery has proved as a far more precise procedure which reduces the risk of erectile dysfunction.
