AMS 700 vs. Coloplast Titan: What Both Devices Actually Are

The AMS 700 (Boston Scientific) and Coloplast Titan are both three-piece inflatable penile prostheses. In each case, the system uses three parts: cylinders in the penis, a pump in the scrotum, and a fluid reservoir in the lower abdomen.

As a result, both devices allow a natural-feeling erection on demand. The rest of the time, the implant stays fully deflated.

Surgeons implant both brands for men with erectile dysfunction that has not responded to less invasive treatments. Consequently, this comparison assumes that implant surgery is already the right path for you. If that is not yet clear, in addition, see our When Should I Consider Penile Implant Surgery guide first.

Design and Deflation: The Real Difference

Both devices share the same three-piece architecture. However, they differ slightly in how the pump deflates the cylinders.

The AMS 700 relies on a squeeze-and-release pump action. This cycles fluid back into the reservoir.

Coloplast Titan, in contrast, uses a One-Touch Release valve. It offers a simpler, single-step deflation.

In practice, most patients adapt to either mechanism within a short learning period. For this reason, therefore, the deflation style rarely determines long-term satisfaction on its own.

AMS 700 vs. Coloplast Titan: What the Evidence Shows

Systematic literature reviews comparing AMS 700 and Coloplast Titan consistently find only minor, inconsistent differences between them. Neither device shows a clear, reproducible advantage across large patient cohorts. Consequently, most specialists rely on their own clinical judgment and hands-on experience with each brand.

Preoperative expectations, moreover, appear to influence satisfaction as much as the device itself. Therefore, a thorough consultation matters more than the brand you choose. One notable exception involves complex anatomy: Titan's wider range of narrower cylinder sizes gives surgeons more options for patients with significant scar tissue or corporal fibrosis, including men who need implant surgery alongside Peyronie's disease correction.

Why Surgeon Experience Matters More Than Brand

The surgeon's skill and experience remain the strongest predictor of a successful outcome, regardless of which implant is chosen. Some surgeons naturally gain more experience with one brand over the other. This often comes down to regional availability or where they trained, rather than any real performance gap.

For this reason, we recommend asking any prospective surgeon directly about their experience with both brands. Ask, specifically, how many of each device they have implanted, and what their own complication and revision rates look like.

Dr. Tuncay Tas discusses both AMS 700 and Coloplast Titan with every implant patient. As a result, the final choice reflects your anatomy, not a single default preference.

This individualized approach, rather than a one-size-fits-all recommendation, most consistently predicts a satisfied outcome years after surgery.

Other Factors Worth Weighing

• Patient reviews: Online forums and men's health communities offer real-world perspectives, though individual experiences vary widely.
• Insurance and cost: Coverage and out-of-pocket cost can differ by brand and provider, so confirm this directly with your clinic before deciding.
• Sizing needs: Both brands offer multiple cylinder lengths and girths, so your specific anatomy may fit one range slightly better.
• Revision history: Ask your surgeon about their own revision rates with each device, not just published averages.

Ultimately, prospective randomized trials may one day settle the debate more conclusively. Until then, in the meantime, an individualized consultation remains the most reliable way to choose. During that consultation, bring a written list of your priorities, whether that means material feel, deflation style, or long-term durability, so Dr. Tas can match the device to what matters most to you specifically.
