Custom Testicle Implants – An Overview

What Are Custom Testicle Implants?

Custom testicular implants are individually designed silicone implants created when standard, off-the-shelf testicle prostheses don’t achieve the desired shape, size, or fit. They are most commonly used for:

• Congenital absence of one or both testicles
  
• Testicular removal after cancer or trauma
  
• Gender-affirming surgery
  
• Revision of unsatisfactory results from standard implants
  
• Cosmetic enlargement or symmetry improvement
  

Dr. Eppley is one of the only surgeons worldwide specializing in fully custom silicone implants for the body, including the testicles.

Why Go Custom?

A custom implant is recommended when:

1. Standard sizes don’t match your anatomy

Commercial implants come in limited sizes. Some patients need:

• Larger dimensions
  
• A specific shape that doesn’t conform to a 0.7 width to length ratio.
  
• A softer more realistic feel
  
• Two different sizes.

2. You need an implant designed around existing anatomy

Examples:

• Only one side has a native testicle
  
• Scar tissue or prior surgeries limit pocket space
  
• You want bilateral implants designed to look symmetrical
  
• You need a special shape that off-the-shelf implants don’t provide
  

3. You want a non-spherical, more realistic look

Many standard implants are too round. Custom implants can be:

• Anatomically contoured
  
• Slightly asymmetrical (just like natural testicles)
  
• Softer or firmer depending on preference
  

How Custom Implants Are Made

1. 3D design based on your measurements
   Measurements come from exam, ultrasound, or 3D imaging.
   
2. Prototype model creation
   A 3D-printed model may be made to confirm size and shape.
   
3. Medical-grade solid silicone fabrication
   These implants are not gel-filled—they are solid silicone, meaning:

• • No risk of rupture
    
  • Very durable
    
  • Long-lasting
    
  • Hollow chamber for soft feel (Malakon Rex design)

1. Sterilization and surgical preparation
   

The entire design process usually takes 3 – 4 weeks.

Surgical Procedure

Placement

• Outpatient 1 hour surgery
  
• Usually under general anesthesia
  
• Incision typically at the midline of the scrotum
  
• Pocket creation to seat the implant securely
  
• Closure with dissolvable sutures
  

Implant Stability

• Free-floating for a natural hang
  
• NO suture fixation

Recovery Timeline

Week 1:

• Swelling, tightness, and soreness common
  
• Supportive garment recommended
  

Weeks 2–4:

• Most swelling resolves
  
• Return to work (depending on job type)
  

Weeks 4 – 6:

• Resume exercise and sexual activity
  
• Implants settle into final position
  

Risks & Considerations

While custom implants are generally safe, risks include:

• Asymmetry of implant position
  
• Infection
  
• Capsular contracture (rare in scrotal implants)
  
• Dissatisfied with size (too big/too small)
