👨🏻🏫 Decisions, Strengths, Preferences
Choosing an inflatable penile prosthesis (IPP) requires balancing surgical considerations, biomechanical goals, and patient lifestyle preferences. The two leading three-piece inflatable devices: the Coloplast® Titan and the Boston Scientific AMS 700™ LGX, address these factors through distinct approaches to cylinder materials, inflation mechanics, pump design, and anti-infection technologies. While both devices demonstrate high patient satisfaction and comparable low long-term infection rates, their clinical profiles appeal to different baseline anatomies and anatomical goals. Please note that the functional insights and many of the comparative observations presented in this article reflect user-reported forum experiences and real-world patient feedback rather than official manufacturer claims.

⚙ Biomechanical Comparison
Cylinders & Expansion Dynamics
Coloplast® Titan
Constructed from Bioflex, a proprietary polyurethane material, the Titan cylinders offer exceptional column strength and axial rigidity.
- Rigidity & Deformity Correction: When inflated, the high tensile strength of Bioflex provides substantial force to overcome severe fibrous plaque for manual modelling in, Peyronie’s disease, or corporal asymmetry. (A Direct Head to Head)
- Girth Expansion: Titan cylinders expand strictly in girth. Expansion is constrained only by the patient’s tunica albuginea, allowing girth potential to exceed 21mm on longer cylinder models. In peer-to-peer patient forums, this notable expansion in girth is commonly described as the ‘Titan flare‘, distinguishing its post-inflation profile from standard uniform cylinder models.
- Flaccid Mechanics: Polyurethane does not contract in length when deflated. Instead, pressure drops, causing the material to flatten and bend. In men with a smaller flaccid baseline (under 5.5inches, the cylinders may fold into internal “dog-ear” creases, producing a firm, semi-pendant flaccid state (“shower profile“).

Boston Scientific AMS 700™
The LGX (Length and Girth Expansion) utilizes a silicone inner cylinder encased in a woven textile fabric sleeve that permits simultaneous length and girth expansion.
- Controlled Expansion: The mesh casing limits maximum lateral expansion to 18mm while allowing up to 20% axial elongation under inflation pressure.
- Soft-Tissue Feel: The silicone construction yields a soft, flexible profile when deflated. The penis contracts naturally into the body, avoiding internal creasing or unnatural flaccid stiffness (“grower profile“).
- Anatomical Limitations: Because maximum girth is capped at 18mm, the LGX may provide less lateral fullness in patients with large corporal capacity or cylinder lengths exceeding 20cm.

Proximal Stability & Distal Design
Titan vs. AMS 700
Proximal Base: The Titan features a 5cm solid proximal rear tip with a wide diameter, offering a tight seat within the corporal crus. This wide anchor reduces axial rotation, side-to-side wobble, or downward drooping at the 3 o’clock position. The AMS 700 LGX uses a 4.5cm proximal base with a 9mm diameter, which provides a slimmer profile but may feel less anchored in patients with larger corporal dilations.
Distal Tips: Titan cylinders incorporate larger, soft-molded distal tips designed to cushion the glans and distribute pressure broadly, reducing apical erosion risks.

📋 Clinical Decision Framework
Choosing between the Coloplast Titan and the Boston Scientific AMS 700 LGX depends largely on individual anatomical needs, clinical presentation, and personal cosmetic preferences. While both devices deliver excellent long-term patient satisfaction, their distinct material mechanics and expansion profiles make each particularly suited for specific patient goals. Ultimately, the choice of device should be guided by a consultation with an experienced urological surgeon who understands your unique clinical history and anatomical requirements, as summarized below:
Furlow Insertion Tool
While Coloplast uses a reusable stainless-steel Furlow tool and Boston Scientific offers a single-use disposable model, both serve the exact same purpose for the patient: ensuring precise internal measurement and cylinder placement. For patients, this means an anatomically custom fit that maximizes functional length, ensures natural placement, and lowers the risk of surgical complications.
👨🏻⚕️ Post-Procedure Expectations
Following penile implant surgery, typical recovery spans four to six weeks, during which men commonly experience mild to moderate pain, localized swelling, and slight discomfort as the surgical sites heal. Patients can generally return home on the day of the procedure and resume light daily activities like walking within a few days, though heavy lifting, strenuous exercise, and sexual activity must be avoided until specifically cleared by a physician. Initial inflation and deflation of the device usually begin between four and six weeks post-operation under medical guidance, after which routine daily cycling helps soften the pump and reduce erect penile pain over time. Helpful Informational vendor leaflets are widly available. While mild swelling and pain are expected, severe pain, extensive discoloration, fever, or drainage from the incision site require prompt contact with your surgeon.

At 2 years post-implant using the Coloplast Titan paired with aggressive sizing and a structured rehabilitation inflation protocol, 96.5% of men reported overall functional satisfaction. Additionally, 77.0% perceived their penile length as equal to or longer than baseline pre-surgery levels, with 64.3% reporting increased satisfaction with penile length compared to before surgery.
⚙️ Durability & Satisfaction: 15-Year Insights
Long-term clinical data tracking patients over a median of eight years demonstrates strong mechanical endurance and high patient satisfaction:
- High Mechanical Survival: Device survival rates reached 93.3% at 5 years, 76.5% at 10 years, and 64.8% at 15 years (overall survival: 89.1%, 71.4%, and 60.5%).
- Uncompromised by Health Factors: Durability was not negatively impacted by age, diabetes, hypertension, obesity, or ED etiology.
- Exceptional Rigidity & Satisfaction: 86.8% of patients were satisfied overall, 83.0% would repeat the procedure, and 90.6% gave top scores for erect rigidity.
- Ejaculatory/Orgasmic Expectations: 60.4% reported achieving orgasm, underscoring the need for proper pre-operative counseling regarding sensation versus mechanical function.
🚫 Common Contraindications
Patients with an active infection present anywhere in the body, especially urinary tract or genital infection. Patients with unresolved problems affecting urination, such as an elevated residual urine volume secondary to bladder outlet obstruction or neurogenic bladder. Patients unwilling to undergo any further surgery for device revision.
⚠ Common Warnings & Considerations
Loss of Natural Function: Implantation permanently eliminates natural erections and alternative non-surgical treatments.
Infection Risk: Higher in patients with diabetes, spinal cord injuries, or compromised immune systems. There are multiple studies on post-operative results and patient satisfaction with malleable prostheses. Documented infection rates range from 1.4% to 8.3%. Published values of erosion (1.4–5.1%) and mechanical dysfunction (0.5% and 12%) are also documented. General patient satisfaction rates in retrospective surveys range from 69–86.6% depending on malleable model.
Erosion: Unmanaged erosion can lead to severe tissue loss and infection.
Anatomical Changes: May cause penile shortening, curvature, or scarring.
Surgical Complexity: Pre-existing abdominal/penile scarring or contractures can make surgery more difficult or impractical.
⛔ Common Potential Complications
Scrotal swelling, autoinflaction, discomfort, angulation/curvature, edema, device malfunction/deflation, pain, difficulty with ejaculation, transient urinary retention, fever, mitration, patient dissatisfaction, infection, hematoma wound leakage, bleeding, delayed wound healing, phimosis, sensory loss cylinder aneurysm, fibrous capsule formation, over/under inflation, erosion, scrotal erythema, genital change, inguinal hernia. See the device manual for detailed information regarding the implant procedure, contraindications, warnings, precautions, and potential complications/adverse events.
🩲 Post-Procedure Comfort Tools
While early scrotal support manages swelling around the pump, keeping the penile shaft comfortable presents a different challenge. Specialized options like Catchfords Non-Friction Recovery Underwear act as a simple post-op comfort tool, providing a soft, cushioned pouch that shields the shaft and glans from rough outer fabrics. By preventing jeans or trousers from catching on delicate suture lines and reducing chafing against sensitive skin, it makes walking and daily movement far more comfortable as you heal.
✨ Restoring Confidence
Taking the step to explore a penile implant is a deeply personal journey toward reclaiming your intimacy, comfort, and peace of mind. Both the Coloplast Titan and Boston Scientific AMS 700 LGX are proven, highly reliable options designed to help you feel like yourself again. The right choice simply depends on your unique body and goals: whether you prefer the maximum girth and firmness of the Titan or the natural flaccid feel and length expansion of the AMS 700. You don’t have to navigate this decision alone: partner with a trusted urological surgeon to review your history and choose the implant that best supports your path forward.
