Suspensory Ligament Release
(Penile Lengthening Surgery)
Suspensory ligament release (SLR) severs the ligament anchoring the penis to the pubic bone, allowing more of the shaft to extend outward. The evidence for this procedure looks very different depending on whether it’s done alone in a healthy man seeking cosmetic length, or alongside penile implant surgery in a man with erectile dysfunction — and that distinction is often blurred in how this procedure gets marketed.
Overview
What this procedure actually does
The suspensory ligament anchors the base of the penis to the pubic bone, holding a portion of the shaft internally. Severing this ligament allows the internal portion to extend outward, increasing visible flaccid — and sometimes erect — length.
The catch is that the ligament also provides structural support during erection. Cutting it can affect the angle and stability of erections, which is the source of the procedure’s most significant and consistently reported risk.
After SLR, providers typically require a period of daily traction device use to help prevent the ligament remnant from reattaching and pulling the gained length back in — without this, some of the surgical gain can be lost over time.
The critical distinction
Two very different situations, often described as the same procedure
This is the single most important thing to understand before considering this surgery — the quality of evidence depends heavily on which of these two situations applies to you.
Healthy men seeking length alone
This is SLR performed by itself in men with normal erectile function, purely for cosmetic length increase. This is the context the SMSNA’s position statement addresses directly, and where caution has been most explicit — citing concerns about penile instability and glans numbness, and noting that published outcome data for standalone SLR remains limited.
Men with ED getting an implant at the same time
This is SLR combined with pubic lipectomy and Z-plasty, performed during penile prosthesis implantation for men with erectile dysfunction — often to address the perceived shortening some men experience after implant surgery. A 2022 randomized controlled trial in this specific context found substantial improvement in sexual satisfaction without serious complications.
The SMSNA’s own review of that 2022 RCT noted that because multiple procedures (SLR, lipectomy, and Z-plasty) were performed together, “it is not clear to what extent the SLR played in the beneficial length gains” on its own — while attributing the reported complications of glanular numbness and penile instability most directly to the ligament release itself.
In other words: even in the better-studied context, the positive result can’t be cleanly credited to SLR alone, while the specific risks of SLR are still clearly present.
What the RCT actually found
The El Gharably et al. 2022 trial
61 men undergoing penile implant surgery for refractory ED were randomized: 31 received SLR plus pubic lipectomy via Z-plasty alongside their implant, 30 received the standard implant procedure alone.
Important limitations: this is a single trial from one center, in men already undergoing implant surgery for ED — not in healthy men seeking cosmetic length alone. It should not be read as proof that standalone SLR is safe or effective for cosmetic purposes.
Real risks to understand
What’s consistently reported
Penile instability — loss of the fixed base angle, sometimes described as a “wobbly” erection
Glans (tip) numbness or altered sensation
Scarring at the surgical site
Retraction — some or all of the gained length can be lost over time without diligent post-op traction
Effect on erect length is less reliable than the effect on flaccid length
Standalone cosmetic outcome data remains genuinely limited compared to the implant-adjunct context
Common questions
Frequently asked questions
Does suspensory ligament release actually increase erect length?
It’s more reliably shown to increase flaccid length than erect length. Some studies report modest erect length changes, but this is far less consistent across the literature than flaccid gains, and the strongest positive trial (2022) was specifically in the context of concurrent implant surgery, not standalone use.
Is standalone cosmetic SLR recommended by urology organizations?
No — the SMSNA’s position statement expresses direct caution about this specific use, citing concerns about penile instability and numbness, and notes that available outcome data is limited. The better-designed randomized trial evidence exists in a different context: SLR performed alongside penile implant surgery in men with ED, not standalone cosmetic use in healthy men.
Why do I need traction after surgery?
The severed ligament remnant can reattach and scar down over time, which can pull the gained length back in. Daily traction device use during recovery is standard practice specifically to prevent this and help maintain the surgical result.
What is penile instability, exactly?
The suspensory ligament normally provides a fixed anchor point that stabilizes the base of the penis during erection. Once released, some men experience a loss of that fixed angle — the erection may feel less firmly anchored at the base, sometimes described as increased mobility or a “wobbly” quality, particularly during penetration.
