How Is The Size Of The Internal Chamber Of A Wrap Around Hollow Testicle Implant Determined?

Q: Dr. Eppley, In hollow wrap around testicle implants does the size of the cavity need to be customized as well so that it fits snugly? Or is there some kind of packing used at the time of surgery to fill in the gap between the natural testicle and the inner wall of the implant?

A: The size of the internal chamber due to material constraints is fixed based on the length and diameter of the external measurements. The testicle is secured inside the chamber by sutures with the hope that it will be adequate to keep it there as it heals. A snug fit is never going to be enough by itself to keep it in place.

If you really wanted to have an ideal match between the size of the internal chamber and the size of the testicle one would get a scrotal ultrasound where the measurements of the natural testicles can be known precisely and then built into the implant design.
