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

If you have never a vacuum pump, it is a cylinder that fits tightly over the penis. The cylinder forms an air-tight seal and the small amount of air inside is removed by the pump. The resulting vacuum pressure stretches the sponge-like tissues within the penis. Pump makers claim the tissues fill with more volume of blood than during normal erections and the quality of erections is improved. They also claim that the penis expands in length and girth as a result and permanent gains are 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 ruptured blood vessels and surrounding tissue will heal in time, continuous use of penis pumps is sure to result in long term damage.

Any positive effects from penis pumps are temporary. Erections gained with the aid of a penis pump only lasts a short time, since they were made for men suffering from poor circulation or diabetes 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 fuller feeling erections come at the price of preventing blood from circulating through the penis for long periods of time which can result in tissue within the penis dying from lack of oxygen. The pump 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 and dependence on the device to achieve erection.

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