We cut into a Mentor Testicular Prosthesis, RME, to point out what happens..nothing.
Do the same to the other unit and you can see the difference.
Yet these reinforced silicone elastomer units are very soft with a natural consistency and optional positional stability, in a suturable polyester reinforced silicone elastomer pad.
See the difference for yourself!

The Differences
1. Reinforced molded silicone elastomer (RME), a cohesive gel substance designed to approximate the weight, shape, and softness of the normal testicle.
2. Optional suturability in a polyester mesh reinforced pad that is rnolded within and flush with the silicone shell. There are no external tabs or loops to cause irritation. Suturing within the reinforced area will not compromise the shell.

Supplied
Individually in a sterile double-wrap packaging system which facilitates transfer to the sterile field.
In the event of contamination, may be resterilized

A competitive testicular prosthesis in the same kink of
cross-section.
