A penile implant is an internal medical device placed by a surgeon to restore sexual function when other treatment options have not helped. It is not an enhancement; it is a reconstructive option for people with persistent erectile dysfunction.
There are two main types: inflatable models with a small pump in the scrotum that creates an erection on demand, and non‑inflatable bendable rods that provide shape. Both types sit inside the body and require an operation and a period of recovery.
This guide explains what the implant does inside the body, what happens during surgery, and how daily use and outcomes compare. It is aimed at people in the United Kingdom researching ED options, those with Peyronie’s disease, and anyone considering reconstructive pathways.
Readers are encouraged to discuss choices with a qualified clinician. Clear, factual steps will reduce anxiety and set realistic expectations about sensation, longevity and the likely result of the procedure.

What a penile implant is and when it is used for erectile dysfunction
Penile implant, penis implant and penile prosthesis are terms that describe the same broad category of surgical device. Clinicians and search results use these phrases interchangeably to denote an internal device placed into the shaft of the penis to restore sexual function when other options fail.
Penile implant, penis implant and penile prosthesis: key terms
The word device here means a manufactured medical product inserted during an operation. This treatment is reconstructive rather than cosmetic: it aims to return function rather than to enhance appearance. Patients will also see references to inflatable and non‑inflatable types; these describe how the device creates rigidity.
When ED treatments are not enough
An implant is usually considered when conservative treatments — tablets, injections or a vacuum constriction device (penis pump) — fail to produce reliable erections for sex. Decision‑making generally moves from least invasive to surgical options, and an implant becomes relevant when outcomes remain inconsistent or unacceptable.
Restoring erectile function with an implant means the device creates penile firmness mechanically, rather than depending on the blood‑flow changes that produce a natural erection. That distinction helps patients understand realistic expectations.
- Clinicians discuss benefits and risks as part of informed consent.
- An implant is for persistent dysfunction when other treatments fail.
Who may be a good candidate for penile implants
Some people reach a point where reconstructive devices become the most reliable path to function. Candidates are assessed on symptoms, anatomy and overall health. A clinician will discuss realistic goals for sexual activity before any decision.
Erectile dysfunction and Peyronie’s disease
Most suitable candidates have long‑standing erectile dysfunction or severe Peyronie’s disease that does not respond to conservative care. When curvature or lack of rigidity prevents intercourse, an operative option may be considered.
When other options have been tried
Good candidacy usually follows attempts with oral medicines and vacuum devices. If these treatments fail to restore reliable function, a surgical path is discussed.
After penis construction or reconstruction
Devices are also used after metoidioplasty or phalloplasty. Planning is specialised; choices between semi‑rigid rods and inflatable systems depend on anatomy and desired flaccid‑erect transition.
- Selection is individual and guided by clinical review.
- Inflatable systems include a small back reservoir and pump; users learn device control as part of long‑term management.

Types penile implants available
Different models offer distinct benefits for comfort, concealment and control. Choice depends on anatomy, lifestyle and personal preference. Clinicians will explain realistic expectations and everyday handling before any decision.
Inflatable versus semi‑rigid rods
Inflatable penile implant systems use two cylinders, a fluid reservoir and a small scrotal pump. The user squeezes the pump to move fluid into the cylinders and creates firmness on demand. A release valve returns fluid to the reservoir after sex.
Semi‑rigid rods are bendable silicone cores that provide constant baseline firmness. The penis is manually positioned up for intercourse and down for concealment. There is no pump or reservoir.
Daily life and practical differences
Different types affect comfort under clothing, spontaneity and handling in public settings. Inflatable devices often read as more natural when flaccid. Rods are simpler to use and need less manual dexterity.
| Feature | Inflatable | Rods | Considerations |
|---|---|---|---|
| Key parts | Cylinders, reservoir, pump | Silicone cores | Named parts affect day‑to‑day handling |
| Flaccid appearance | More natural | Less natural | Impacts concealment |
| Ease of use | Requires pump control | Simple repositioning | Consider manual dexterity |
How do penile implants work in the body
Inflatable systems act as a closed loop of fluid, tubing, pump and paired cylinders. Two cylinders sit inside the erection chambers (corpora cavernosa). Thin tubing links those cylinders to a reservoir tucked beneath the lower abdominal muscles. A small pump resides under the scrotal skin for easy, discrete access.
Reservoir, cylinders and body placement
The reservoir stores sterile fluid out of the way beneath abdominal muscles. Cylinders replace or sit within erectile tissue and create rigidity when filled. The pump in the scrotum is positioned so it can be squeezed without pressing the testicles.
Pump action, flow and inflation
Repeated squeezes of the scrotal pump transfer fluid from the reservoir through tubing into the cylinders. This raises thickness and firmness to the chosen level. The erection can be held for as long as desired because the device maintains pressure in the cylinders.
Release valve and deflation
To deflate, the user depresses a release valve on the pump. Fluid flows back to the reservoir and the penis returns to a flaccid state for everyday comfort.
Semi‑rigid rods
Semi‑rigid devices use two bendable silicone rods placed in the same chambers. They provide constant structural support and need no pump or fluid movement. The wearer simply positions the shaft up for sex and down for concealment.
- Key point: components sit within erectile tissue and do not extend into the glans.
- Operation is mechanical and user‑controlled, with predictable inflation and deflation steps.
What happens during penile implant surgery
Surgery begins with careful planning to match the device to a patient’s anatomy. The pre‑operative pathway is an assessment, discussion of goals and a clinic appointment where sizing and a bespoke plan are agreed.
Pre‑op appointment and measurement for a custom fit
At the appointment the surgeon measures internal dimensions to select the largest safe cylinders. This clinical “custom fit” aims to restore a length close to the stretched penile measurement before surgery.
Assessment includes health checks and informed discussion so the chosen implant suits the individual’s anatomy and expectations.
Placing cylinders into the corpora cavernosa
During implant surgery the two cylinders are inserted into the corpora cavernosa, the erection chambers inside the shaft. This means the device replaces or supports erectile tissue rather than sitting superficially.
Positioning the pump in the scrotum and the reservoir in the lower abdomen
The small pump sits under loose scrotal skin between the testicles for discrete, easy access. The reservoir is placed under the lower abdominal muscles out of sight.
Tubing links cylinders, pump and reservoir to form a closed system. After recovery, patients learn inflation and deflation steps in clinic as part of rehabilitation and device familiarisation.
“Clear discussion and accurate measurement are key to a predictable result.”
- Clinic assessment and an appointment set expectations and sizing.
- Cylinders occupy the corpora cavernosa; the pump and reservoir are tucked away for comfort.
- Post‑operative training helps users gain confidence with inflation and deflation.
Recovery and getting back to sexual activity
Recovery follows a clear arc: initial rest, gradual healing and step‑wise reintroduction of sexual activity. Early care focuses on wound healing and reducing swelling. Most people begin practical familiarisation only once the surgeon gives the all‑clear.
Healing timeline and adjusting to the device
Healing often takes several weeks. Comfort improves as swelling falls and the scrotum settles.
Adjusting to an implant can take time; for some it is a few weeks, for others a couple of months. Regular clinic follow‑ups guide the pace of recovery and safe return to sex.
Learning to use the pump: practical tips for inflation and deflation
The pump sits under the scrotal skin and is located by gentle feeling. Repeated squeezes move fluid into the cylinders; inflation may take a minute or two to reach preferred firmness for an erection.
To deflate, press the release valve and allow fluid to return to the reservoir. This becomes quicker with practice and builds confidence in everyday use.
- Start slowly: follow clinician advice before resuming sexual activity.
- Practice: try inflation and deflation out of concern for privacy until it feels discreet.
- Seek help: ask the surgical team for device‑specific training if manual dexterity or pain is a problem.
What results to expect: erection, sensation, size and how long the implant can last
After recovery, the device becomes the primary way to achieve an erection. With an inflatable system, pumping usually takes a minute or two to reach full firmness. Semi‑rigid rods are always firm and are simply positioned for intercourse.
Can they become erect whenever they choose?
An inflatable system allows the user to become erect on demand by operating the scrotal pump. Semi‑rigid options give a constant firmness that is shaped into a ready position.
Does it feel the same and affect orgasm or ejaculation?
The implant stiffens the shaft mechanically but does not change skin sensation. Most people report that orgasm and ejaculation remain unaffected after healing.
Size and the glans
Implants do not usually make the penis larger than its pre‑operative stretched length; some recall natural erections as longer. The glans does not harden with inflation because cylinders do not occupy the head.
Where concern about head softness exists, clinicians may suggest treatments to improve blood flow to the glans.
| Outcome | Typical result | Notes |
|---|---|---|
| Control | On demand (inflatable) or fixed position (rods) | User training makes operation discreet |
| Sensation | Usually unchanged | Orgasm/ejaculation generally preserved |
| Size perception | Similar to stretched pre‑op length | Some report reduced perceived length versus remembered natural erection |
| Durability | Around 20 years on average | When worn out, revision surgery replaces the device |
Longevity: most devices last about two decades. If a unit fails, revision surgery typically removes and replaces it. After healing, the implant is usually unnoticeable in daily life.
Conclusion
This guide summarises the key facts to support a decision about a penile implant. Internal components create mechanical rigidity, giving an on‑demand erection with an inflatable system or steady firmness with semi‑rigid rods.
These devices suit people with persistent erectile dysfunction or Peyronie’s disease who have not found acceptable results from conservative treatments, and those in specific reconstructive scenarios.
Choice rests on daily feel, willingness to use a pump, acceptance of a firmer baseline and readiness for surgery and recovery. There are risks and outcomes vary, so a specialist urology consultation is essential for personalised advice.
Realistic expectations: reliable erections, usually unchanged sensation and orgasm, no guaranteed enlargement, and long device lifespan with possible future revision. Use this guide to frame questions for your consultation about type, recovery and long‑term care.
