The Penuma is a crescent-shaped piece of medical-grade silicone inserted under your penis skin to make your penis longer and wider. It’s provided in three sizes: large, extra-large, and extra-extra-large.

The tissues that give your penis its shape are composed largely of two types:

• Corpus cavernosa: two cylindrical pieces of tissue that run parallel to each other along the top of your penis
• Corpus spongiosum: one cylindrical piece of tissue that runs along the bottom of your penis and surrounds your urethra, where urine comes out

Your Penuma device will be designed to fit your specific penis shape. It’s inserted into your shaft over the corpus cavernosa, like a sheath.

This is done through an incision in your groin area just above the base of your penis. The device stretches the penis skin and tissues to make your penis look and feel larger.
