We actually take a very, very fine needle, about the size of a human hair in diameter, and inject the equivalent of liquid Viagra into the man’s penis. And he will get a firm, sustained erection, and then we can study it. Typically we study it with an ultrasound device. So actually I can see the artery flowing blood as during the erection.
I can see all the tissues, what happens to the tissues. I can see the thickness of various chambers. I can see if tissues are healthy versus scarred. It’s a fabulous opportunity to gain insight into what’s happening with the erection. I always tell patients, if you go to your car dealer and you have a sound at 60 miles an hour that you don’t have at any other miles per hour, and the man looks as the car is parked and says, “Gee, I think I know what’s wrong with it,” he can’t really do that. So you can’t go to a regular doctor with an erection problem and be studied in a flaccid state. That makes no sense. So you need to be in a specialized facility where having an erection and testing it is how you’ll find out what’s wrong.
