A penis pump uses negative pressure to draw blood into the vessels of your penis to help produce an erection. Following the device’s instructions carefully is important to avoid injury and other unwanted outcomes.
Also called a vacuum pump or vacuum erection device, a penis pump typically includes:
- a cylinder that slides over the penis
- a seal or ring that fits around the base of the penis
- a battery-powered or manual vacuum mechanism that extracts air from the cylinder, prompting an erection
A penis pump may not be the best option for individuals with mild erectile dysfunction (ED), and it might not work for very severe ED.
However, if you have been diagnosed with moderate ED, a penis pump could be a nondrug therapy worth considering.
How do you use a penis pump?
Using a penis pump may feel awkward at first, but it’s a relatively straightforward tool to operate.
- Begin by placing the cylinder over your penis. You might apply a lubricant to prevent irritation from the tube.
- If the device is battery-operated, switch it on; if it’s manual, use the hand pump to begin extracting air from the cylinder.
- The reduced air pressure will encourage blood to flow into the vessels of your penis. It can take a few minutes for an erection to develop.
- When you have an erection, release the vacuum, remove the cylinder, and proceed with sexual activity.
Most systems include a constriction or cock ring that you place at the base of the penis to help sustain the erection by restricting blood outflow.
After achieving an erection, put the ring around the base of the penis and then take off the cylinder. Keep the ring on for no longer than 30 minutes, since extended use can impair circulation and damage the penis.
What are the benefits of using a penis pump?
Penis pumps produce erections for the majority of users. How long the erection lasts varies by person, but around 30 minutes is common.
These devices are generally safe and do not carry the systemic side effects associated with ED medications. They are also noninvasive compared with penile implants, which require surgical procedures.
Over time, a penis pump is often less costly than recurring medication expenses because it can be used repeatedly without ongoing purchase of pills.
Pumps can be particularly useful after treatments such as prostate surgery or radiation for prostate cancer.
Another advantage is that a pump can be used alongside ED medications or other therapies without added risk. Some users find that routine use helps encourage more natural erections.
Are there side effects or risks to using a penis pump?
Most people with moderate ED can use a penis pump safely. However, if you take blood thinners such as warfarin (Coumadin), your risk of bleeding complications may be higher.
Blood-clotting disorders or conditions that increase bleeding risk may make use of a penis pump unsafe for you.
It’s critical to follow the manufacturer’s directions. Excessive vacuum pressure can harm the penis.
There is a risk of minor bleeding beneath the skin, which can cause small red spots (petechiae) on the penis.
Frequency of use depends on how your body responds. Some people can use a pump multiple times a day, while others may only need it occasionally.
What to look for when choosing a penis pump
Many models are available, and a number of them are not cleared by the U.S. Food and Drug Administration (FDA) or other health authorities.
Over-the-counter (OTC) pumps are sold in drugstores, adult shops, and online. Since many of these are not FDA-cleared, their safety and effectiveness are not guaranteed.
When selecting a pump, choose one with a vacuum limiter. This safety feature prevents the internal pressure from getting excessively strong, which could injure the penis.
The size of the constriction ring is also crucial. It should be snug enough to be effective but not so tight that it causes pain. You may need to try several sizes to find the correct fit.
Be wary of advertisements claiming vacuum devices permanently enlarge the penis. There’s no credible evidence that such claims are true, and attempting to use a device for enlargement risks injury.
Do you need a prescription to purchase a penis pump?
Before purchasing a penis pump, speak with a healthcare provider. A prescription helps ensure you obtain a device that’s FDA-cleared.
Not every pharmacy stocks these devices, so you may need to call around to find one. A urologist or other clinician may be able to point you to local pharmacies that carry FDA-approved pumps.
How much does a penis pump typically cost?
Prices vary by brand and features. Models with added functions or accessories generally cost more.
Because penis pumps are recognized as a treatment for ED, many insurers cover some or all of the expense. If you have insurance, contact your plan provider to check your coverage.
The bottom line
A penis pump can be a safe, effective, and accessible nondrug treatment for ED. If you’re wondering whether a pump is right for you, talk to a healthcare professional to get personalized guidance.
