Erection self-test - Risks

Alternative Names

Nocturnal penile tumescence (NPT) stamp test; Nighttime penile tape test

What the risks are:

There are no risks.

Special considerations:

This test is rarely done anymore. It test is not very accurate and there are better tests available to monitor blood flow. This test does not indicate many important factors of sexual dysfunction, such as quality, duration, or number of erections during the night.
