Hollow Chamber Testicle Implants (Malakon Rex) – Improved Design, Softer Feel

Hollow chamber testicle implants are a newer variation of testicular prostheses designed to feel more natural and reduce some drawbacks of traditional solid implants.

What they are

Instead of being completely solid (usually low durometer silicone elastomer), hollow chamber implants have a small internal cavity. The outer shell is still medical-grade silicone, but the hollow interior allows the implant to compress more like a natural testicle. More compressibility = softer feel

Potential advantages

• More natural feel
  The hollow space allows slight deformation with pressure, closer to a real testis.
• Lighter weight
  Reduced mass may lessen long-term discomfort or downward pull on the scrotum.
• Improved patient satisfaction
  Some patients report better tactile realism compared with solid implants.

Potential disadvantages / considerations

• Durability concerns
  Such hollow designs are not known to make them more prone  to collapse or rupture over a patient’s lifetime.
• Limited long-term data
  Solid implants have decades of outcome data; hollow designs have less published longevity data.
• Availability
  The hollow chamber design is proprietary to Dr. Eppley and his patients.
• Cost
  Is more expensive than standard solid implants.

How they compare to standard solid implants

Typical candidates

• Patients seeking maximum realism
• Men bothered by the firmness of traditional implants
• Secondary implant patients dissatisfied with prior prostheses

Surgical considerations

Placement technique is similar to standard testicular implants. One placement advantage of the hollow chamber design is that the internal cavity can be filled with antibiotic solutions or powders to act as an infection-prevention mechanism. This is possibope becasue of the 4mm opening on one end of the implant which is needed to make the internal hollow chamber in the manufacturing process.
