I always strongly encourage my patients to use a vacuum erection device as a means of stretching the penis and improving blood flow in that area. Here is the information I provide my patients regarding a vacuum erection device.

Vacuum erection device:
Regular use of a VED helps maintain penile length, improve blood flow, and prevent scar tissue (fibrosis) after prostate surgery or radiation, or if you've had longstanding erectile dysfunction. Think of it as “physical therapy” for your penis.

You can purchase a medical-grade VED through the Mayo Store at the websites below. The major difference in cost is whether it is electronic (battery operated - more expensive) or manual pump (less expensive). Otherwise they are all equally good and perform the same function. A medical-grade vacuum device is like getting prescription eyeglasses—built for safety, comfort, and effectiveness. Cheaper pumps online are more like toy sunglasses—they may look similar but don’t work as well, may not fit properly, and can even cause harm. For penile rehabilitation after surgery or radiation, I recommend a medical-grade device because it’s safer, lasts longer, and is designed for your health needs.

The Mayo Clinic store has several different types of devices available for purchase.

Step-by-Step Instructions
1. Get Set Up
o Make sure the device is clean and assembled.
o Apply a small amount of water-based lubricant around the base of the cylinder and on the penis to help create a seal.
2. Position the Device
o Place the cylinder snugly against your body at the base of the penis.
o Make sure there are no gaps so air does not leak out.
3. Create the Vacuum
o Use the hand pump (or battery pump, if included) slowly.
o You will see the penis gradually enlarge and become firm.
o A gentle stretching feeling is normal; stop if you feel pain.
4. Rehabilitation Use (without constriction ring)
o For rehab, do not place the tension ring.
o Pump until the penis is stretched/erect, hold for about 1–2 minutes, then release.
o Repeat this cycle 5–10 times in one session.
o Goal: use the device at least 3–4 times per week (daily if possible).
5. If Using for Intercourse (with constriction ring)
o After pumping, slide the tension ring onto the base of the penis.
o Remove the cylinder; the ring will help maintain erection.
o Do not keep the ring on for longer than 30 minutes.

Tips for Success
• Be patient—results improve with consistent use over weeks to months.
• Some mild bruising or discomfort at first can happen; it usually improves with practice.
• Always use water-based lubricant (not oils or lotions).
• This is not just for sex—using the device regularly helps preserve penile health, even if you are not sexually active.
