Testing the Blood Flow in the Penile Arteries

When a man becomes sexually excited, blood flows to the penis and is absorbed by the spongy tissue there.  This engorges the penis and makes it erect.  The more blood flowing into the penis, the longer and harder it becomes.  Most men don’t actually get the maximum amount of blood flow during an erection, so their penis isn’t quite as long or as hard as it could be.  Male enhancement pills can increase circulation so a man can reach his maximum length, but if there is any damage to the arteries in the penis, even this powerful pill may not be able to help.  How can you find out if damaged arteries are behind your erection difficulties?

There are a few different tests your doctor can perform.  One thing that can be done is a Doppler ultrasound.  This will allow him to check the blood pressure of the penile arteries.  If the penile blood pressure index is too low, it’s possible you may have penile vascular disease.  If that’s the case, your doctor may suggest one of several different courses of action.

While male enhancement pills can increase the blood flow to your erection, making it harder, if you have damaged veins and arteries, you may need medical assistant to repair the problem and give you a normal sex life.  However, enhancement pills can overcome a lot of sexual issues naturally, allowing you to avoid prescription medication that comes with a number of side effects.
