AMS 700 CX vs Coloplast Genesis vs AMS LGX — Penile Implant Devices Compared

Three penile prosthesis devices are available at certified Busan facilities. The choice between AMS 700 CX and Coloplast Genesis is the most common decision — made at pre-consultation based on anatomy, prior pelvic surgery, and patient preference.

Questions

Neither is universally better. AMS 700 CX has the longest published clinical track record and the highest satisfaction data at 5 years (92–95%). Coloplast Genesis has a narrower pump profile — preferred when prior pelvic surgery (prostatectomy, bladder surgery) has created scrotal scarring. The decision is anatomy-based, not brand-based.
AMS 700 LGX adds length expansion (up to +2cm in the inflated state) through a lengthening cylinder design. It is chosen when the patient's stretched penile length (SPL) is a primary concern. The LGX has a slightly lower satisfaction rate than the CX in published data (88–92% vs 92–95%). The CX is the primary recommendation for most patients.

How to Choose Between AMS and Coloplast — A Patient Guide

Most patients defer entirely to their surgeon's recommendation — which is reasonable given the surgeon has direct knowledge of your anatomy. However, understanding the differences helps you ask better questions at consultation.

Choose AMS 700 CX If...

  • You want the most extensively published clinical data (longest track record)
  • You have no prior pelvic surgery or scrotal scarring
  • Your surgeon primarily uses AMS devices (most Busan surgeons do)
  • The InhibiZone antibiotic coating is important to you

Choose Coloplast Genesis If...

  • You have had prior prostate surgery, bladder surgery, or scrotal procedures — the narrower pump may fit better in scarred tissue
  • Your surgeon has specific training and preference for Coloplast
  • The slightly lower device cost is a factor (USD $8,800 vs $9,200 entry-level)

Choose AMS 700 LGX If...

  • Length expansion is a specific concern alongside girth — LGX provides up to +2cm in erect length
  • You accept the slightly lower satisfaction data (88–92% vs 92–95% for CX)
  • Your surgeon has assessed your anatomy as benefiting from length expansion
