A comprehensive comparison of surgical penile implants versus non-surgical filler enhancement—helping you understand the differences in results, costs, risks, and recovery.
Men considering penis enhancement face a fundamental choice: surgical implants that provide permanent results, or non-surgical fillers that offer proven enhancement with less commitment. Both approaches have legitimate roles depending on your priorities, risk tolerance, and goals.
This guide provides an objective comparison to help you understand which approach might be right for your situation.

Understanding the Two Approaches
Silicone Penile Implants
Penile implants are subcutaneous silicone devices surgically placed beneath the penile skin to create permanent girth enhancement. An FDA-cleared silicone implant is the primary device used in the United States.
How it works: Through an incision in the scrotum, a crescent-shaped medical-grade silicone implant is positioned around the penile shaft and secured with sutures. The implant stretches tissue over time, creating permanent girth and potential length enhancement.
Hyaluronic Acid Fillers (Penis Enlargement Injections)
Filler-based enhancement uses injectable hyaluronic acid—the same technology used in facial aesthetics—placed beneath the penile skin to add volume and increase girth.
How it works: Using a microcannula technique, medical-grade HA filler is injected along the penile shaft in an office procedure. The filler integrates with tissue to create immediate, natural-appearing girth enhancement.
Results Comparison
Girth Enhancement
Implants: Average girth increase of up to 2 inches. Results develop over 6-12 months as tissue stretches around the implant and a capsule forms.
Typical results — yours depend on your starting size and the volume you choose, and your doctor tells you what to expect for you at your consultation.
Fillers: Girth increase of up to 2 inches, depending on volume. Results are usually immediate and visible the same day.
Verdict: Both approaches achieve similar girth enhancement of up to 2 inches, depending on volume.
Length Enhancement
Implants: Some patients experience flaccid length increase as the implant’s weight stretches tissue over time. This is variable and not guaranteed. Erect length increases are uncommon.
Fillers: Modest flaccid length increase (typically ~0.75 inch) from the added weight. No significant erect length change.
Verdict: Neither approach reliably increases erect length. Both may modestly improve flaccid length.
Duration of Results
Implants: Permanent. The implant remains as long as it’s in place, though complications could require removal.
Fillers: Temporary. Results last about two years and gradually diminish as the body metabolizes the filler. Maintenance treatments required.
Verdict: Implants win on permanence, but this is a double-edged sword—complications are also permanent.

Natural Feel
Implants: Most patients and partners report natural feel after full healing (6-12 months). The capsule that forms around the implant contributes to natural texture. Initially may feel firmer.
Fillers: Feel natural shortly after swelling resolves (2-4 weeks). HA integrates with tissue and has similar properties to natural tissue.
Verdict: Both achieve natural feel, though fillers achieve this faster.
Procedure Comparison
Surgical Requirements
Implants:
- Surgical procedure requiring general anesthesia
- Operating room setting
- 45-60 minute procedure
- Incision in scrotum
- Drain tube placed for 2-3 days
Fillers:
- Office-based procedure, typically under local anesthesia only
- No operating room, no sedation
- procedure of under an hour
- Tiny entry points (no significant incisions)
- No drains or tubes
Verdict: Fillers are significantly less invasive.
Recovery Time
Implants:
- 2-3 weeks before returning to normal daily activities
- 6-8 weeks before sexual activity
- Full healing and final results at 6-12 months
Fillers:
- Return to normal activities same day or next day
- Sexual activity resumes at 7 days
- Final results visible at 2-4 weeks
Verdict: Fillers have dramatically shorter recovery.
Risk Comparison
Full list of risks and complications →
Implant Risks
- Infection: ~3% of cases; may require implant removal
- Seroma (fluid collection): ~5% of cases
- Temporary sensation changes: 1.5% report temporary numbness
- Implant complications: Shifting, perforation, need for removal
- Surgical risks: Anesthesia complications, bleeding, scarring
- Revision rate: Approximately 10% require revision or removal
Full list of risks and complications →
Filler Risks
- Bruising and swelling: Common, temporary
- Lumps or irregularities: Uncommon; usually correctable
- Infection: Rare
- Vascular occlusion: Very rare but serious
- Allergic reaction: Very rare
Verdict: Fillers have a lower overall risk profile. Crucially, most filler complications are reversible (HA can be dissolved), while implant complications often require surgical intervention.

Reversibility
Implants: Can be removed, but removal is a surgical procedure. Post-removal, some retraction may occur, and the penis may not return exactly to pre-implant state. Previous implant placement also disqualifies patients from future filler procedures due to tissue changes.
Fillers: Reversible. Hyaluronidase enzyme dissolves HA filler within 24-48 hours if desired, which allows correction of unsatisfactory results; an implant comes out only with a second operation.
Verdict: Fillers offer clear reversibility advantage.

Candidacy Requirements
Implant Candidates Must:
- Be circumcised (or undergo circumcision 8+ weeks prior)
- Have no prior penile enhancement procedures (including fillers)
- Refrain from tobacco/drugs for 30 days before and 90 days after
- Be in good general health for anesthesia
- Have realistic expectations and appropriate psychological profile
Filler Candidates Must:
- Be in reasonably good health
- Have no severe bleeding disorders or allergies to HA
- Have realistic expectations
- Circumcision is not required
- Prior enhancement procedures may or may not affect candidacy (evaluated individually)
Verdict: Filler candidacy requirements are less restrictive. Notably, choosing fillers preserves the option of implants later if desired; choosing implants eliminates the option of fillers forever.
Cost Comparison
Implant Costs
- One-time cost: $10,000-$19,000
- Includes implant, surgery, anesthesia, facility fees
- No maintenance costs unless complications arise
Full list of risks and complications →
Filler Costs
- Initial treatment: $4,000-$8,000
- Maintenance treatments about every two years
- 10-year estimated cost: $20,000-$40,000
Verdict: Implants have lower lifetime cost if no complications occur. However, initial cost is much higher. Fillers have lower entry cost but accumulate over time.

Decision Framework: Which Is Right for You?
Consider Fillers If:
- You want to try enhancement before committing to permanent change
- You prefer minimal downtime and non-surgical approach
- You value reversibility
- You’re uncircumcised and prefer not to get circumcised
- You want to preserve options for future decisions
- You’re willing to maintain results with periodic treatments
- Lower initial cost is important
Full list of risks and complications →
Consider Implants If:
- You strongly prefer permanent, one-time solution
- You’re fully committed to enhancement (already done extensive research)
- You can afford the higher upfront cost
- You’re willing to undergo surgery and 6-8 week sexual abstinence
- You’re circumcised (or willing to be)
- You’ve never had prior penile enhancement procedures
- Long-term cost savings matter more than initial cost
Recommendation
For most men new to enhancement, doctors affiliated with Upsize™ recommend starting with fillers. The reasons:
- Trial without permanent commitment: Fillers let you experience enhancement and determine if it provides the benefits you hoped for—without irreversible change.
- Preservation of options: You can always pursue implants later if you decide you want permanent enhancement. You cannot pursue fillers after an implant.
- Lower risk profile: Non-surgical procedure with fewer and more reversible complications.
- Faster recovery: Back to normal life and sexual activity much sooner.
Implants make sense for men who have done extensive research, are fully committed to permanent enhancement, meet all candidacy requirements, and prefer a one-time surgical solution.

Combining Approaches
A reasonable pathway for many men:
- Start with filler enhancement to experience results
- Maintain with fillers for several years
- Evaluate whether permanent enhancement via implant makes sense long-term
- If implant is chosen, allow filler to fully dissolve first, then proceed
This pathway provides the benefits of both approaches: trying enhancement with lower commitment, then converting to permanent solution if desired.
