Since weight hanging penile enlargement systems aren't really a device, penis pumps could be considered the first penile enlargement device ever created. These pumps have been selling for a long period of time and their popularity never seems to decline. Before you consider buying one of these devices there are a few things you need to know about the device being hazardous to your health.

If you have never a penis pump, it is a cylinder that fits tightly over the penis. The cylinder forms an air-tight seal around the penis and the small amount of air inside is removed by the pump. The vacuum pressure fills the sponge-like tissues within the penis with blood. Pump makers claim the tissues fill with more volume of blood than normal and the quality of erections is improved. They also claim that the penis expands in girth and length as a result and permanent enlargement is achieved. However, these claims are false. Subjecting any part of the human body to such pressure under vacuum conditions results in rupturing blood vessels just like "hickies" on someone's neck. Although the penis and blood vessels heal in time, repeated use of penis pumps is very likely to result in long term damage to your penis.

The pump only yields short-term positive effects. Erections achieved with the aid of penis pumps only last a short time, since they were made for men suffering from diabetes and poor circulation to achieve erection. The suction power of the pump does fill the penis to maximum capacity but will being to leave as soon as the pressure is removed. The stronger erections come at the price of preventing blood from circulating through the penis for a long period of time which can result in tissue within the penis dying from lack of oxygen. The vacuum also puts pressure on nerve cells within the penis which results in numb feeling or desensitized erections. Unsafe amounts of pressure being applied on the penis can also result in curved or deformed penises as well as the inability to get an erection naturally.

Any man that is interested in safe and effective penis enlargement should avoid such a hazardous device. Penis extender devices and exercise programs can achieve enlargement in safer and faster ways.
