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.

Penuma is a permanent silicone that’s been cleared (though not yet fully approved) by the U.S. Food & Drug Administration (FDA) for penile enhancement. It’s made of malleable, medical-grade silicone, so it looks and feels like a natural penis. This relatively new procedure is currently performed only in select cities in the U.S., but we expect its popularity and availability to grow. Its manufacturer claims that clinical studies have shown very low adverse-event rates (infection in 3% of cases and seroma [fluid buildup] in 5% of cases) and high patient satisfaction.

Penile disassembly is a more invasive form of sliding elongation surgery in which the degloved shaft is completely severed just below the head of the penis. The gap is then filled with a section of rib cartilage taken from the patient and reassembled by suturing the degloved tissues back into place. While less commonly used, the surgery can be effective for men with micropenis, congenital defects, or deformities resulting from penile cancer,


The vacuum pump. This is a cylinder that sucks out air. You stick your penis in and the resulting vacuum draws extra blood into it, making it erect and a little bigger. You then clamp off the penis with a tight ring -- like a tourniquet -- to keep the blood from leaking back into your body. What are the drawbacks? The effect only lasts as long as you have the ring on. Using it for more than 20 to 30 minutes can cause tissue damage. This is sometimes used as a treatment for erectile dysfunction, but has not been proven to actually increase the size of the penis.
