How It Feels

Nocturnal penile tumescence (NPT) test

A nocturnal penile tumescence (NPT) test does not cause any discomfort, but you may feel embarrassed about doing the test. Remember that it is important to find the cause of your inability to have an erection and you do not need to feel embarrassed about the test.

Intracavernosal injection test

During the intracavernosal injection test, you will feel a sharp, stinging pain at the base of your penis from the needle. If you feel a burning or aching pain during the erection, tell your doctor immediately.

Doppler ultrasound

The ultrasound does not cause any pain. If you get a medicine or device during the test to cause an erection, you may feel embarrassed and the shot may hurt.
