A vacuum erection device, also called a "penis pump," can help you get and keep an erection. It's a good option if you can't or don't want to take medication for erectile dysfunction. In fact, it works for up to 90% of men.
A vacuum erection device usually has three parts: a plastic tube (called a cylinder) that fits over your penis, a stretchy band (often called a “cock ring”) that helps keep the erection, and a pump, either manual or electric, that helps create the erection.
Each vacuum erection device is a little different, but they work by removing the air from the cylinder, which creates a vacuum. This vacuum helps draw blood into your penis and causes an erection. It can take up to 10 minutes to get an erection. Once you do, you remove the cylinder and place the constriction band at the base of your penis to keep the erection.
It’s very important not to leave the ring on for more than 30 minutes.
Vacuum erection devices are not recommended if you take blood thinners or have a bleeding disorder.
Frequently asked questions
Q: Does using a penis pump hurt?
A: The constriction band may feel a little uncomfortable, and you may have trouble ejaculating. Your penis could also feel cold or look blue. This is normal as long as it’s within the 30-minute limit. If it stays cold or blue after removing the band, see a doctor.
Q: Can I use a penis pump and medication?
A: Yes, it's safe to use a penis pump along with PDE5I medication.
Q: Are penis pumps safe?
A: Penis pumps that are approved by regulatory bodies like the EMA or FDA have been tested and are safe and effective. Avoid pumps that claim to make your penis bigger or don’t have a pressure limit. These are not safe and could cause harm.
- You don’t need a prescription to buy a vacuum erection device, but getting one makes sure you get a safe device. That’s why it’s a good idea to talk to your doctor if you're having trouble with erections.
- A regulatory body is an organisation responsible for setting rules and making sure that products meet certain safety and quality standards. Examples include the Food and Drug Administration (FDA) in the U.S. and the European Medicines Agency (EMA) in Europe. These organisations make sure that medical devices, drugs, and other products are safe for use.
