What is a penile implant?
A penile implant is a medical device placed surgically inside the spongy erectile tissue (corpus cavernosum). It is not visible from outside and cannot be noticed when dressed. The aim is to provide mechanically the rigidity needed for intercourse when the natural erection mechanism cannot be restored.
The implant does not change sexual desire, ejaculation or the sensation of orgasm; these continue through their own natural mechanisms. The implant addresses the erection alone.
Types of implant
There are two main groups in practice, and the choice is made individually:
- Malleable implant: permanently semi-rigid, positioned up or down by hand. The mechanism is simple and it is easier to use in terms of manual dexterity.
- Inflatable (three-piece) implant: made up of cylinders, a pump and a fluid reservoir. Because it can be inflated and deflated with the pump, it offers an appearance closer to natural erection and relaxation; its mechanism is more complex.
Who is it considered for?
A penile implant is not a first-line treatment. It usually comes into play after other options have been tried without an adequate response. The situations most often seen are:
- Advanced erectile dysfunction due to long-standing, difficult-to-control diabetes
- Persistent erectile dysfunction developing after radical prostate cancer surgery or other pelvic surgery
- Advanced vascular insufficiency that has not responded adequately to medication and injection treatments
- Cases with marked curvature due to Peyronie’s disease alongside erectile dysfunction
- Selected cases in which severe venous leak has been identified
Before and after the operation
A detailed information consultation takes place at the decision stage. Expectations, what the implant can and cannot do, possible complications and the alternative options are all discussed openly. For those found suitable, a general pre-operative assessment, blood glucose control and preparation with regard to infection are carried out.
After the operation, the recovery period, follow-up appointments and training in how to use the implant are planned. When you can return to sexual activity is determined by the physician according to how healing progresses.
Risks and what you should know
As with any surgical procedure, penile implant surgery carries risks: infection, mechanical failure, pain, changes in sensation and, rarely, the need to remove the implant are the principal ones. The risk of infection is higher particularly in people with diabetes whose blood glucose is not under control.
Because placing an implant requires using the erectile tissue inside the penis, it is regarded as an irreversible procedure. The decision is therefore taken only after all the options have been weighed and the person has been informed in detail.
Frequently asked questions
Is a penile implant noticeable from outside?
The implant is placed entirely within the body and cannot be noticed when dressed. With malleable types the penis is permanently semi-rigid and needs positioning; with inflatable types it stays flaccid when not in use.
Does an implant affect desire and ejaculation?
No. The implant addresses the erection alone. Sexual desire, sensation and ejaculation continue through their own natural mechanisms.
How long does an implant last?
Implants are manufactured to be used for many years; but because it is a mechanical device, failure remains possible over time. If it fails, replacement may be needed. It would not be right to give a fixed figure, and regular review is advised.
How soon after surgery can sexual activity resume?
This varies with the individual and with healing, and is determined by the physician. Swelling and tenderness are expected findings in the early period.
Is it necessary to try other treatments first?
As a rule, yes. A penile implant comes into play in cases that have not benefited from other methods. In some advanced cases, however, the physician may consider it appropriate to assess this option directly.
