Penis pumps could be thought of as the first penile enhancement device ever created, as hanging weights on your penis isn't really a device. The popularity of these pumps has not declined over their long presence on the market. Before you think about buying one of these devices there are a few things you need to know about the device being hazardous to you.

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 within is removed by the pump. The pressure fills the sponge-like tissues within the penis with blood. 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 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 ruptured blood vessels and surrounding tissue will heal in time, continuous and over-zealous use of penis pumps is very likely to result in long term damage.

Any positive effects from penis pumps are short-term. Erections gained with the aid of penis pumps only last a short time, as they were made for men suffering from poor circulation and diabetes to achieve an 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 extended period of time which can result in tissue within the penis dying from lack of oxygen. Penis pumps also put pressure on nerve cells within the penis which results in desensitized or numb-feeling 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.

For any man that is looking for safe penis enlargement should avoid the hazards of penis pumps. Penis exercise programs and extender devices can achieve gains in size in safer and faster ways.
