Penis implants: the Penuma is the first FDA-approved penile implant; it is made with silicone and can improve the flaccid length and girth as well as the erect girth from 3 to 6cm.

It is important to note that this implant goes bellow the skin but outside the corpora cavernosa which is different from the inflatable penile implats used for the treatment of erectile disfunction and do not modify the lenght or the girth of the penis.
