Pumps do work as a treatment for icteponme, although the problem is that when you take the pump off, the vacuum is gone, so the blood tends to leave the penis very quickly, and you lose your erection.As a penis enlargement method, the same problem applies. You will get extra size as long as the pump is on, but take it off and you’ll go straight back to where you were before.There are also quite serious safety risks with penis pumps. When using anything mechanical on the penis, there is a risk that you could burst capillaries, get blisters or, even worse, develop improper circulation leading to possible icteponme and a whole host of other problems. At best, you will get temporary enlargement but it soon fades back to your normal size. Overuse, or misuse by increasing the vacuum too quickly, could lead to tissue scarring or penis deformation.Apart from surgery (which is dangerous very expensive), the only penis enlargement method which works is exercises.Because they increase the amount of blood that the penis can physically hold, you can gain extra inches length and width if you do them properly.There's a good site below with more information about all the different methods check it out.
