Penis pumps for ED: can they help with erectile dysfunction?

Penis pumps have been helping people manage erectile dysfunction (ED) for decades. Yet, they remain a commonly overlooked treatment option, probably because the name makes them sound less like a medical device and more like a novelty item.

Here’s what the research shows about penis pumps for ED, and what to know before buying one.

Short answer: yes, for most people. Penis pumps are included as a recognized treatment option in the American Urological Association's (AUA) ED clinical guidelines. Plus, studies report success rates ranging from 69%–93% among people who use them correctly (with exact figures depending on the population and device).

Penis pumps won't fix the root cause of ED (no external device can), and they do take some getting used to. But if you're looking for something that works without a prescription, or you can't take ED pills (PDE5 inhibitors) like Viagra (sildenafil) or Cialis (tadalafil) due to other health conditions or medications, a vacuum erection device (VED) is a well-supported option.

Get started

A penis pump is a simple, non-invasive device that helps produce an erection without medication. It has three main parts: 

1. A plastic tube that fits over the penis

2. A hand or battery-powered pump attached to the tube

3. A tension ring (also called a constriction ring) that slides to the base of the penis to keep things in place. (It’s generally recommended to keep the ring on for no more than 30 minutes to avoid injury to the penis.)

Here's how it works: Activating the pump removes air from the tube, creating a vacuum that draws blood into the penis. Once an erection develops, the tension ring is slid to the base to trap that blood and maintain the erection long enough for sex.

You might also see penis pumps listed as vacuum erection devices (VEDs) or vacuum constriction devices (VCDs), but they refer to similar devices.

Using a penis pump is straightforward. Most people get the hang of it within a few tries:

1. Apply water-soluble lubricant to the base of the penis. This helps create a tight seal between the device and your body, which is what allows the vacuum to work properly.

2. Place the plastic tube over the penis. Press it firmly against the body to form a seal.

3. Activate the pump. This removes air from the tube, creating a vacuum that draws blood into the penis. It may take a few minutes for a full erection to develop. That's completely normal.

4. Slide the tension ring to the base. Once an erection develops, carefully slide the ring off the tube and onto the base of the penis to trap blood and maintain the erection.

5. Remove the tube. The erection should last long enough for sex.

One important rule: Don't leave the tension ring on for more than 30 minutes. Cutting off blood flow for too long can cause injury. So set a timer if you need to.

Penis pumps work well for a wide range of people with ED. But they can be especially useful for those in certain situations, such as:

• People who can't take PDE5 inhibitors. If you take nitrates for a heart condition, or have certain cardiovascular contraindications, oral ED medications like sildenafil, tadalafil, or vardenafil might not be safe for you. A VED gives you an effective option that doesn't involve medication at all.

• People who prefer a non-drug approach. Some people simply want a mechanical option, and that's completely valid. VEDs have decades of clinical use behind them.

• People recovering from prostate surgery or radiation. After prostate surgery, the nerves responsible for natural erections are temporarily disrupted. Meaning, spontaneous erections — including those during sleep — are reduced or absent. Without them, penile tissue can deteriorate over time, and that's where a VED can help fill the gap.

• People who want support during penile rehabilitation. Regular VED use maintains blood flow during recovery from prostate surgery — a process called penile rehabilitation — and may also help preserve penile length.

• People who want to combine treatments: VEDs can be used alongside ED medications or a penile implant to enhance results.

While they may be especially useful for the individuals listed above, penis pumps may also not be a fit for others. The AUA guidelines recommend using VEDs with caution for people taking blood thinners (anticoagulants), with a bleeding disorder, or a history of priapism. Some guidelines recommend caution when using a penis pump if you have Peyronie’s disease, too. 

If any of these apply to you, speak with a healthcare provider before using one.

Penis pumps are safe for most people. But like any treatment, there are a few side effects worth knowing about before you get started. These include: 

• Petechiae. These are tiny red or purple dots that can appear on the skin of the penis after use, caused by minor bleeding just under the surface. They may look alarming, but they tend to be harmless and clear up on their own.

• Numbness, color change, or coldness. These can occur while the tension ring is in place, due to restricted blood flow. They typically go away as soon as the ring is removed.

• A "hinged" erection. VED-produced erections can feel less firm at the base than a natural erection, which can cause the penis to pivot slightly. This is normal and something most people adjust to with time.

• Trapped or uncomfortable ejaculation. Some people find that the tension ring restricts ejaculation or makes it feel different. Some devices come with rings that have a small cutout specifically designed to help with this.

• Bruising. This is often related to incorrect use or too much vacuum pressure, both of which are easy to avoid once you're familiar with the device.

The good news is that most of these side effects are mild and avoidable. Using a device that’s cleared by the US Food and Drug Administration (FDA) correctly and sticking to the 30-minute limit for the tension ring helps keep the risk low.

Individual responses to treatment can vary. Talk with your healthcare provider before using a VED to make sure it's appropriate for your specific health situation and any medications you're currently taking.

Want to see how a penis pump stacks up against other options? Here's a quick breakdown:

These options aren't mutually exclusive. VEDs can be used alongside ED medications or following penile implant surgery in some cases.

Most penis pumps fall into two main categories based on how the vacuum is generated. Both can be effective when used with an FDA-approved device.

1. A manual pump is hand-operated to generate the vacuum. 

2. A small battery-powered pump generates the vacuum electronically.

You may also see water-based pumps (sometimes called hydropumps), typically marketed for penis enlargement or general sexual enhancement rather than as medical devices for ED.

For ED specifically, an FDA-cleared manual or battery-powered VED is the safer, evidence-backed choice.

Penile implant pumps — also called inflatable penile prostheses (IPPs) — are a completely different device from an external VED.

Rather than sitting outside the body, an IPP is surgically implanted inside the penis, with cylinders placed in the corpora cavernosa and a pump positioned in the scrotum that inflates the device when an erection is desired.

IPPs are typically considered when other ED treatments haven't worked. They're not reversible: Once implanted, the device replaces the body’s natural erectile mechanism. For the right candidate, though, satisfaction rates as high as 90% have been reported, with good long-term reliability.

Given its permanence, an IPP is a decision best made after a conversation with an experienced provider.

Where you buy a penis pump matters. Devices sold through novelty stores or unregulated online platforms aren't built to medical standards and can cause real injury. Here's what to look for when choosing a penis pump or VED for ED:

• FDA approval. Make sure the device is cleared as a medical device, not marketed as a novelty item. This is the most critical factor.

• A vacuum limiter. This built-in safety feature prevents pressure from building too high, which is what causes most injuries.

• A manual safety release. This lets you release pressure quickly if something doesn't feel right.

• A reputable medical supplier. Your healthcare provider can recommend specific models or write a prescription, which may mean the device is covered by your insurance.

If you're unsure where to start, your healthcare provider can help you find something safe and suitable. Any decision about starting a new treatment should be made with their guidance.

Personalized ED treatment for you.

Using penis pumps for ED is a well-established, non-drug approach with a solid safety record when used correctly. They work by creating a vacuum that draws blood into the penis, with a tension ring used to maintain the erection. Here's a quick recap:

• Penis pumps, or VEDs, have decades of clinical backing. VEDs are listed as a recognized ED treatment and have been studied for both on-demand use and post-surgical recovery.

• They can play a role after prostate surgery. Daily use may help maintain penile blood flow and support size preservation during recovery.

• Penis pumps are not for everyone. People taking blood thinners, with bleeding disorders, or with a history of priapism should speak with a healthcare provider before use. 

• You should only use FDA-approved devices. An FDA-approved model with a vacuum limiter and safety release is essential. Novelty pumps can cause real harm.

• Combination use (i.e. a penis pump with another ED treatment) can help address ED. Pairing a VED with ED medication or using one after a penile implant procedure may improve results for some people.
