- Contains the cylinders, pump, and fluid reservoir
- Done through 1 incision
- Mimics the natural erection in that it is hard when desired, and soft when not sexually active
- Easy to use, simply squeeze pump to inflate and hit a button to deflate
- High degree of penile rigidity
- In the soft state, is fully flaccid and hidden: would be unnoticeable even if naked in a locker room-
- Fully concealed: single patients do not even need to tell their partner
- Is a more involved surgical operation, though still done in about 25 minutes
- Acts as a tissue expander, so offers maximal length and girth by stretching over time
