Tests for Erection Problems
Risks
Nocturnal penile tumescence (NPT) test
There are no problems from having the nocturnal penile tumescence (NPT) test.
Intracavernosal injection test
The intracavernosal injection test has a small chance of causing:
- Bleeding at the injection site.
- Bruising or swelling around the injection site.
- An erection that lasts for 3 or more hours. This condition, called priapism, is a rare side effect of some medicines used for this test. If priapism occurs, it usually can be reversed using another medicine.
Doppler ultrasound
There are no problems from an ultrasound test. If a device is used to cause an erection, you may have some mild discomfort. If a shot of medicine is used, you have the same chance for problems as the intracavernosal injection test.
