A numbing cream, followed by an injected numbing agent, prevents pain. “Depending on the patient’s goals, a filler is chosen and then injected into the corpus cavernosum of the penis [two columns that contain most of the blood during an erection]. The filler is then worked through the penis, to achieve a uniform increase in length and girth,” says Cedar Grove, New Jersey, physician Dr. Muhammad Mirza in a RealSelf Q&A.
Streching devices and penis pumps are increasingly popular, often selling for hundreds of US dollars. We recommend staying away from these devices, because using them can lead to permanent damage of the cavernous body and blood vessels of your penis. In worst case, the usage of penis extenders can result in erectile dysfunction, the inability to get and maintain an erection. Although many surgeons, including our advisory team, keep warning about them, these warnings are unheard and ignored by many men. Reconstructive surgery for a penis damaged by excessive and wrong use of streching devices is very expensive and rarely results in full recovery.
An extender is designed to provide gentle and painless penis traction. The device fastens around the base of the penis and around the corona glans (head), offering a fully adjustable traction apparatus. When you gradually increase the longitudinal force on the shaft of the penis, the body’s natural reaction to this force is multiplication of tissue cells and gradual expansion of the penile tissue. In other words, the penis gradually adds tissue for a larger and longer penis. But be careful with these devises, some of them can traumatize your penis.
