A vacuum erection device typically consists of a plastic tube (called a cylinder), a rubber or silicone band (called a constriction band, or more commonly known as a “cock ring”) which is used to keep the erection once achieved and either a manual or electric pump, which is used to create the erection.
Using a vacuum erection device
While each vacuum erection device varies by manufacturer, they work by removing the air from the cylinder, which creates a vacuum. The vacuum encourages blood flow into the penis, causing an erection. It can take up to 10 minutes to achieve an erection, but once achieved, you simply remove the cylinder and slip the constriction band around the base of your penis.
It is very important not to leave the ring on for more than 30 minutes.
Vacuum erection devices are not recommended if you take medication to prevent blood clotting or if you have a bleeding disorder.
Frequently asked questions about vacuum assisted devices for erectile dysfunction
Does using a penis pump hurt?
The constriction band can cause discomfort, and it’s not uncommon to have trouble ejaculating. You may also find your penis is cold to touch or appears blue in colour. While this is normal within the 30-minute window of safe sexual activity, if you experience a cold or blue penis after the constriction ring has been removed, you should speak to a medical professional.
Can I use a penis pump and medication?
Yes, it’s safe to use a vacuum erection device and PDE5I medication.
Are penis pumps safe?
Devices that have been approved by a regulatory body, such as the European Medicines Agency (EMA) or Food and Drug Administration (FDA) have been tested in clinical trials and deemed to be both safe and effective. You should avoid devices that are advertised as penis enlargement devices, and those without a vacuum limiter. These devices are not approved by the regulatory bodies, and you risk damaging your penis by using devices that allow unlimited pressure.
Although you don’t need a prescription to buy a vacuum erection device, getting a prescription ensures you will be given a safe device. This is another reason why it’s important to speak to your doctor if you are having erection problems.
