What you can expect

Using a penis pump requires a few simple steps:

• Place the plastic tube over your penis.
• Use a hand pump or electric pump attached to the tube to create a vacuum inside the tube and pull blood into the penis.
• Once you have an erection, slip a rubber constriction ring around the base of your penis. This helps you maintain the erection by keeping blood inside the penis.
• Remove the vacuum device. The erection typically lasts long enough to have sex.

Don't leave the tension ring in place for more than 30 minutes — cutting off blood flow for too long might injure your penis.
