What is the tape test for erectile dysfunction (ED)?

Madeleine M. Castellanos, MD
One way to know if the cause of your partner's erectile problem is physical or psychological is to do the tape test.

Normally, a man can develop an erection during the night or upon awakening. This body response is known as nocturnal penile tumescence and is proof that he's physically able to have an erection.

If your guy isn't sure, he can wrap a very thin and narrow piece of tissue paper around his flaccid penis, secured with a little bit of scotch tape. It's likely that if he has an erection when he's sleeping the paper will break to some degree. If he easily gets an erection during sleep, but not in other situations, the cause is likely psychological. If not, the reason is likely physical.
