What Is a Penile Implant?
A penile implant is a medical device placed entirely inside the body — nothing is visible from the outside. It replaces the function of the spongy erectile chambers (the corpora cavernosa) with cylinders that you control. When you want an erection, you make one; when you're done, you return the penis to a soft, natural-looking state.
Sensation, orgasm, and ejaculation aren't controlled by the erectile chambers, so for most men those are preserved — the implant restores rigidity, not the other sensations.
It's also surgery, and it's irreversible: placing the device removes the natural erectile tissue's ability to function on its own. That's why it sits at the considered end of the treatment conversation — not because it's a last resort to be feared, but because it's a permanent commitment that, for the right man, is genuinely life-changing.
Malleable vs. Inflatable
Malleable (Semi-Rigid) Implants
Two bendable rods placed in the erectile chambers. The penis stays permanently firm — you bend it up for sex and down toward the body for concealment. They're simpler, have no mechanical parts to fail, are easier to use for men with limited hand strength or dexterity, and cost less. The trade-offs: the penis is always semi-rigid (concealment takes practice), and it tends to feel less natural than an inflatable. A good fit for select men — for example, those with poor manual dexterity or certain medical situations.
Inflatable Implants — The Modern Standard
The large majority of men choose an inflatable device because it most closely mimics a natural erection: rigid and larger when you want it, soft and concealed when you don't. The modern standard is the three-piece inflatable: two cylinders in the penis, a pump with a deflation valve in the scrotum, and a fluid reservoir hidden in the abdomen/pelvis. Because the reservoir holds plenty of saline, it gives the firmest erections and the softest, most natural flaccid state.
How the Three-Piece Works
- 1
Squeeze and release the small pump in your scrotum several times (usually about 10–15 squeezes).
- 2
Each squeeze moves sterile saline from the abdominal reservoir into the two penile cylinders.
- 3
The cylinders expand and stiffen, creating a firm, controllable erection that lasts as long as you want.
- 4
When you're finished, press the deflation valve on the pump; the saline drains back to the reservoir and the penis becomes soft again.
Device Anatomy
The Three Components
Paired Cylinders
Two inflatable cylinders implanted inside the corpora cavernosa — the same chambers that fill with blood during a natural erection. When inflated, they produce a rigid, natural-feeling erection.
Scrotal Pump
A small pump placed in the scrotum. Squeezing it transfers fluid from the reservoir into the cylinders to create an erection; pressing a deflation valve returns fluid to the reservoir.
Fluid Reservoir
A saline-filled reservoir placed behind the pubic bone. It stores the fluid that inflates the cylinders and is completely concealed within the body.
Choosing Your Device: Titan vs. AMS 700
Two manufacturers make excellent three-piece inflatable implants. The right choice depends on your anatomy and your surgeon's experience — here's what actually differs. Both produce very high satisfaction, so this isn't about a 'better' device — it's about the right fit.

Boston Scientific AMS 700
What the differences mean for you
- Titan tends toward high pressure and rigidity; AMS toward a very natural feel — but the differences are small in real life.
- LGX uniquely adds length on inflation, helpful if you're concerned about post-surgery shortening.
- Both yield roughly 1–3% infection rates; real-world rates depend heavily on surgeon technique and patient factors (notably diabetes).
- The Titan pump is easier for weak hands; the AMS deflation valve is easier to locate.
- Your surgeon matches the device to your anatomy — this is a conversation to have together.
Satisfaction, Durability & Length
Once a man has healed and learned the device, most report it feels like a natural part of them — over 90% of patients and partners report satisfaction in large series. Modern implants typically last about 15–20 years, with mechanical survival around 90% or better at 5 years.
But a lot depends on how you treat the device. Treat it like a work truck — use it every day, put 300,000 miles on it in 18 months — and it may need service sooner than the Cadillac that stays covered in the garage and only comes out for the Sunday evening cruise.
A Word on Size
An implant is sized to fit your own anatomy — it restores the erect length your tissues allow, not a larger one. The LGX cylinder can preserve or modestly increase length over time; otherwise, implants aren't a lengthening procedure. Many men who'd lost length (after prostate surgery, or from severe ED) feel they regain what they'd lost, because they can now achieve full rigidity again.
Risks & Complications
Implant surgery is safe and routine in experienced hands — but every surgery has risks, and you deserve the honest list. The two that matter most are infection and mechanical failure.
Infection (~1–3%)
The most serious complication. Because a device is involved, an infection usually means the implant must be removed. Antibiotic coatings, careful surgical technique, and optimizing health beforehand (especially blood sugar in diabetics) keep this rate low.
Mechanical Failure
Uncommon and lower with modern devices, but possible over many years; it's the main reason a device might eventually need replacement. The good news is that revision is usually straightforward — the body has already formed a smooth capsule around the original implant, which actually makes the second surgery easier.
Other Risks
Bleeding or scrotal bruising, pain during healing, change in sensation, erosion of the device through tissue (rare), and the possibility that the result isn't quite what you pictured. Glans (head) sensitivity and natural lubrication aren't changed by the device, but the glans doesn't engorge with an implant, which some men notice.
Surgery & Recovery
The men happiest with their implants are the ones who went in well-informed. Use this as your checklist — before you decide, before surgery, and through recovery.
Setting Expectations
Read this with your partner if you can.- An implant restores rigidity, not the other sensations. Orgasm, ejaculation, sensation, and desire come from systems the device doesn't touch — most men keep them, but the erection itself is now device-driven.
- The glans (head) won't swell as it once did, because only the shaft chambers are replaced.
- Length is set by your anatomy. Discuss length honestly beforehand; if shortening worries you, ask about the LGX option and pre-op stretching/rehab.
- Choosing an implant is permanent. The natural erectile tissue won't work on its own afterward — there's no going back to pills or injections.
- There's a learning curve. The first weeks of using the pump feel awkward; nearly everyone masters it.
Questions to Ask Your Surgeon
- How many implants do you place per year, and what are your infection and revision rates?
- Which device do you recommend for my anatomy — Titan or AMS 700, and which cylinder — and why?
- Given my concerns about length, is the LGX (length-expanding) cylinder right for me?
- What incision will you use (penoscrotal vs. infrapubic), and how will that affect recovery and scarring?
- What's your plan to minimize infection — and do I need to optimize my A1c or stop any medications first?
- What should my partner and I realistically expect for feel, length, and spontaneity?
- What happens if the device fails years from now — what does revision involve?
Pre-Op Safety Checklist
- Diabetics: optimize your A1c before surgery — high blood sugar raises infection risk. Most surgeons won't proceed if blood glucose on the morning of surgery is over 200.
- Stop anticoagulants/blood thinners only as your surgeon instructs.
- Treat any active infection (skin, urine, dental) before the date.
- Stop smoking — it impairs healing.
- Arrange help at home for the first few days, and loose, supportive underwear.
The Procedure
The operation itself is shorter and easier than most men expect. It takes about 45–90 minutes under general or spinal anesthesia. The surgeon places all three components through a single small incision (either at the penis-scrotum junction, called penoscrotal, or just above the penis, called infrapubic). Most men go home the same day or after one night.
Recovery Timeline
Rest, ice, and scrotal support; some swelling and bruising are normal. Most men return to desk work within about a week.
Light activity; swelling settles. Keep the device deflated.
First 'pump-cycling' session, usually taught in clinic — you begin inflating and deflating to learn the device and keep tissue from tightening around it.
Typically cleared for sexual activity once healing is confirmed.
Full comfort and confidence; the device feels like part of you.
Post-Op Pearls
- Take all prescribed antibiotics and keep follow-up visits — early infection control is everything, as is tight perioperative glucose control for diabetic men.
- Don't inflate the device until your surgeon says so (usually around week 4).
- No sexual activity or cycling until cleared (typically ~6 weeks).
- Some men are taught to keep the penis pointed upward on the abdomen early on to guide healing position — follow your surgeon's instruction.
- Call promptly for fever, spreading redness, increasing pain, or drainage — these can signal infection.
Why Surgeon Volume Matters
Penile implant surgery is a technically demanding procedure. Outcomes — including infection rates, device survival, and patient satisfaction — are significantly better in the hands of high-volume surgeons. Dr. Mutter is a designated AMS 700 Center of Excellence, reflecting his surgical volume, outcomes data, and commitment to patient education. When choosing a surgeon for this procedure, volume and specialization matter.
