Penis pumps use air pressure to expand the blood vessels in the penis to help achieve an erection. Proper use of the pump  can reduce the risk of side effects. 

Penis pumps are one of several non-drug treatment options for erectile dysfunction (ed). These devices are relatively easy to use. However, it is important to be careful as it can cause harm and side effects if used incorrectly. Penis pumps are also called vacuum pumps or  vacuum erection pumps. The device consists of: 

•  Tube that fits the penis 
• A seal or ring that fits around the base of the penis 
• A battery-powered or manual vacuum pack that removes air from the tube to cause an erection. 

Penis pumps may not be a good choice for people with mild erectile dysfunction and  may not be effective for severe erectile dysfunction. However, if you have been diagnosed with moderate erectile dysfunction, you may want to consider a penis pump as a non-drug treatment option.
