Penis pumps (or constriction vacuum devices) are one of the oldest methods of fighting impotence. They are made of an acrylic cylinder with a pump that may be attached directly to the end of the penis. A constriction ring or band is placed on the cylinder at the other end, which is applied to the body. The cylinder and pump are used to create a vacuum to help the penis become erect; the band or constriction ring is used to help maintain the erection.

Intercourse can be attempted with the constriction band in place to help maintain the erection. The band can be left on safely for up to 30 minutes to allow for successful intercourse. Studies suggest that about 50%-80% of men are satisfied with the erections obtained with the help of penis pumps. So they are relatively safe to use if you don't want or if you cannot make use of Viagra or other approved erectile dysfunction medication.

If you do intend to use one, read the label and be sure you follow the instructions. Penis pumps can be dangerous if used improperly. Take caution when using one and ensure that whatever pump you use has a reliable pressure gauge and that you follow the instructions closely.

Furthermore, using the wrong kind of vacuum pump and using it too often can burst blood vessels in the penis, peel skin, cause general pain, and soreness. They also tend to thin out the penis, making it very weak and reducing the duration of erections. There are some cases of penis pumps even deforming the penis. Some men have found out that after using a penis pump for a period of time, the only way they would be able to obtain an erection is with the pump.

But do penis pumps work when it comes to making your penis larger? And why are they found among male enhancement products when penis pumping has only one application - and that's to help you achieve erection when using it. You can find frauds and scams everywhere on the internet and with the excellent results that penis extenders have proved, some marketers have thought about enriching their stores with penis pumps claiming they will do the same thing for you: lengthen your penis that is.

Penis pumps and penis stretchers are not the same thing and they don't work in the same manner. They are not interchangeable! Penis pumps do nothing more than help you keep the blood within the penile cavity with the help of a constriction ring. It's true that by forcing more blood into the penile cavity you can force it to expand to accommodate a larger volume of fluid, but it's not safe to attempt this type of exercises using vacuum devices.

Too much vacuum can cause large blood vessels to rupture and any kind of penile injury is the last thing you want. Penis stretchers on the other hand are a lot easier to control. They are made to be used often and precisely for enlarging the penis. Penis extender devices work by applying a constant traction force along the shaft of your penis. Over time this triggers the reaction capacity of the tissues which causes cellular multiplication. And cellular multiplication means a longer, thicker penis.

Penis stretchers are safe because you can absolutely control the traction force you apply and you can also stop at any time you feel discomfort. Even a very low traction force applied to the penis can produce good results for beginners, which is great news for people who want to try penis enhancement but are afraid of injuries. Not needing to exercise on an erect penis is an added bonus and it means the risk of injury is very small compared to penis pumps.
