Erectile Dysfunction: The Inability To Achieve Or Maintain An Erection

What Is Erectile Dysfunction?


Erectile dysfunction refers to the inability to achieve or maintain an erection due to decreased blood flow to the penis or the inability of the penile muscles to relax during sexual activity. It is particularly common in men over the age of 40, as a result of the decrease in testosterone production, although it can also be attributed to other underlying conditions or factors. It can be a temporary problem or a permanent condition, depending on the cause. Erectile dysfunction is very common, with more than 3 millions cases per year in the U.S. alone.

Your primary care physician can diagnose erectile dysfunction based on your medical history and reported symptoms. They will likely order a series of diagnostic tests to evaluate blood flow to the penis and rule out underlying conditions. These diagnostic tests may include penile ultrasonography and penile nerve testing.


The most common method of treatment for erectile dysfunction is medication. These medications can boost libido and increase blood flow to the penis. Some men choose to use devices called “penis pumps” to increase blood flow to the penis immediately before intercourse. Severe cases may require penile prosthesis surgery, in which artificial rods are implanted into the penis.
