A vacuum erection device (VED), commonly called a penis pump, is a simple mechanical way to produce an erection without drugs. It consists of a plastic cylinder that fits over the penis, and a pump that removes air from the cylinder to create vacuum pressure. This vacuum gently pulls blood into the penile tissue, causing an erection. Once the penis is erect, a rubber tension ring (also called a constriction band) is slid from the end of the tube onto the base of the penis to trap the blood and keep the penis hard for up to 30 minutes. You then remove the pump/cylinder, and you can proceed with intercourse. After finishing, the band is taken off to restore normal circulation.
Effectiveness
Vacuum pumps work for most men, regardless of the cause of ED. They can produce a firm erection suitable for sex in the majority of users. This makes them a great option if medications are not effective or not recommended for you. Pumps are often suggested for men who cannot take ED drugs (for example, due to drug interactions or side effects), and they are also used as part of penile rehabilitation after prostate surgery (to help preserve erectile tissue).
Because the pump doesn’t rely on body chemistry, even men with severe medical conditions can often use it successfully. It may take a little practice to get the technique right, but many couples find it to be a satisfactory solution. It’s non-invasive (no surgery), and after the initial cost of buying the device, it’s inexpensive to use.
Side effects and considerations
A vacuum device is generally safe. The most common issues are minor and temporary, such as mild bruising or a feeling of coolness/numbness in the penis due to the constriction band. The band can also restrict ejaculation (semen might not come out, or only dribble out, because the exit is partially closed by the ring). This doesn’t harm you and the semen will simply drain out when the ring is removed. Some men (and their partners) say the pump process can feel a bit awkward or unromantic, but others incorporate it into foreplay. It’s important to use the device as instructed to avoid injury – for example, using the safety vacuum limiter so you don’t pump too hard, and not leaving the tension ring on for longer than recommended (usually 30 minutes maximum).
Availability
Good quality penis pumps are medical devices. In the USA, you can get a pump with a prescription (which might be covered by insurance in certain cases) or you can also buy one over-the-counter (for example, online or from medical supply stores) without a prescription. If you buy one on your own, it’s wise to ask a doctor which models are safe and effective.
In the UK, some vacuum pumps are available through the NHS (if a specialist recommends it), but they’re not always provided by the NHS and you might be directed to purchase one yourself if needed. Either way, in both countries there are reputable brands available.
Always ensure any device you use has a vacuum limiter and comes with instructions. Many hospitals have ED clinics or sexual health clinics where they can demonstrate how to use a VED properly.
Overall, vacuum pumps are a reliable, drug-free option. They have been used for decades and have a high success rate when used correctly. They can also be used alongside other treatments (for example, with medications or after injection therapy, though not at the exact same time).
