What Is an Erection Self-Test?
An erection self-test is a procedure a man can do by himself to determine if the cause of his erectile dysfunction is physical or psychological.
It is also known as the nocturnal penile tumescence (NPT) stamp test.
Why Is an Erection Self-Test Performed?
According to a review published in the Journal of Endocrinology, the average healthy pubescent male will have between three to five spontaneous erections a night. Those with physiological difficulties, such as a spinal cord injury, will not (Benson, 2005).
Erectile dysfunction can be caused by physical, emotional, or mental problems. This test helps determine if a man’s erectile functions are impacted by physical problems.
The test is considered outdated. More reliable tests, such as nocturnal penile tumescence (NPT) testing using the RigiScan test, are now available. Also, it is becoming increasingly difficult to find postage stamps, which are used in the test, that aren’t already sticky on the back.
However, it may be used as a discreet way of testing yourself if you are embarrassed to discuss the subject with a doctor.
How to Prepare for an Erection Self-Test
You will need to buy four to six postage stamps. The denomination of the stamps does not matter, but they should be the roll style with the dry glue on the back.
Abstain from alcohol or any chemical sleep aids for two nights before the test. Avoiding caffeine during these days is also advised to ensure you get a good night’s rest.
How an Erection Self-Test Is Performed
Prior to going to bed, change into a pair of briefs or boxer-brief underwear. Take enough stamps to circle the shaft of your penis.
Pull your flaccid penis through the fly in your underwear and ensure the majority of your pubic hair remains close to your body.
Moisten one of the stamps on the roll and wrap the stamps around your penis. Overlap the stamps in the roll to ensure they will stay securely in place. It should be snug enough so the stamps break apart if you have an erection. Place your penis back inside your shorts and go to bed.
For best results, sleep on your back so the stamps aren’t disturbed by your movement.
Do this three nights in a row.
When you awake in the morning, check to see if the roll of stamps is broken. You could have had an erection in your sleep if the stamps are broken. This indicates that your penis physically functions properly.
There are no risks associated with an erection self-test. There may be some slight discomfort if the stamps used during the procedure become stuck to pubic hair, but these easily become unstuck during a morning shower.
After an Erection Self-Test
Failure to have an erection (not breaking the stamps) during the course of the test suggests that your erectile dysfunction is caused by a physical problem. If so, you should see your doctor.
This test only indicates whether you are capable of having an erection, but does not indicate why you might have problems getting or maintaining an erection. Failure to have an erection during sex may be psychological in nature, and would require a discussion with a doctor or a counselor.
Talk to your doctor if you regularly experience erectile dysfunction. While many men don’t feel comfortable about talking about the subject, it is a fairly common condition, especially as you age.
There have been numerous advances—namely in pharmaceutical drugs (e.g. Cialis or Viagra)—that can help men with erectile dysfunction.
