Recently introduced to our collection of sex toys have been both male penis pumps and female vacuum pumps, sometimes with vibration. The male penis pump is used to increase the size of the penis (over time - measured in months). It is also used as an aid to getting and maintaining an erection, usually in conjunction with a cock-ring of some kind.

This is a cylinder that is fitted over the penis, and a pump that creates a vacuum. There are two very different uses for penis pumps. 

Firstly, they can act as valuable sex aids for men who have difficulty achieving and maintaining an erection, as they can be used to achieve an erection, with a compressive ring on the base of the penis then maintaining the erection. This is best used along with a cock ring of some sort.

Secondly, a "Penis Pump" can also be used to temporarily increase the size by increasing the amount of blood and other fluids that are in the corpus cavernosa and surrounding tissue. These temporary gains are well proven and abundantly documented on various "hobbyist" sex toy websites. However, the effectiveness of penis pumps increasing absolute penis size is very hard to determine. Some practitioners follow the overload principle which stipulates that as a part of the body is pushed past its limits the natural healing process will accommodate for the extra stress when making repairs i.e. muscles get bigger and in this case tissues lengthen and swell. Over time it is believed that regimen of pumping and or other methods will cause gains, however minor, to be realized.

Many people have a well-justified concern for the safety issues involved in pumping. If used improperly the pumping process can cause blood vessels to burst as well as blisters. In some cases the testicles can be unexpectedly pulled into the cylinder and cause an extreme amount of pain as well as possible injury. It is also believed that the rim of the cylinder can cut into the skin and over time cause damage to the ligaments surrounding the penis. However, these dangers are easily avoided by a little instruction and a lot of patience. Far too often newcomers to the practice will use too much vacuum (anything greater than 10 mm Hg) and hurt themselves before ever reading any guides to the hobby

Attempts at using vacuum cleaner base units as opposed to penis pumps for this purpose have resulted in severe injury; the machine causes too much vacuum and there is also danger in contacting the vacuum fan unit both scenarios can cause severe damage.
