Penile Implants
What is a Penile Implant?
A penile implant, also called penile prosthesis, is a device that reverses erectile dysfunction by enhancing the rigidity of the erectile bodies.
It is designed to mimic the look and performance of a natural erection. All components are concealed within the body and cannot be seen from the outside.
The penile implant cylinders / rods reside into the corpora cavernosa. No tissue is removed to place the cylinders, the cylinder simply fill the space that previously filled with blood when one was potent.
A penile implant does not disrupt the flow of urine or ejaculate. It does not alter the sensation of the penis.
How do I know if I need a Penile Implant?
Penile implants are typically considered when:
Other Treatments Have Failed: Medications, injections, or lifestyle changes haven't effectively treated erectile dysfunction.
Desire for a Permanent Solution: Men prefer a long-term fix without the need for ongoing medication or injection therapy.
Preference for Spontaneity: The ability to achieve an erection whenever desired, without planning around treatments.
Penile atrophy: Patient is experiencing shortening or loss of girth related to underlying ED and wishes this to cease.
Peyronie’s Disease: Men with deformities caused by Peyronie’s disease and erectile dysfunction can often address both issues simultaneously with a penile implant. The added benefit is that the implant acts as a tissue expander and can prevent further Peyronie’s-related changes.
The Penis Anatomy
The penis contains three cylinders held together by your connective tissue and skin.
The two cylinders that run along the top are the erectile bodies or corpora cavernosa, which get hard when they fill with blood and make penetration possible. They are wrapped in a strong fibrosis layer, called the tunica albuginea.
The third cylinder – corpus spongiosum – runs underneath the two erectile bodies and surrounds the urethra as it travels to the end of the penis. As the name suggests, this cylinder remains softer during erection to allow passage of semen during ejaculation.
The head of the penis – the glans – is a direct extension of the corpus spongiosum.
What are the Different Types of Penile Implant?
There are two main types of penile implants:
Malleable (Semi-Rigid) Implants: These bendable rods are always firm but can be positioned as needed for sexual activity or concealment.
Inflatable Implants: These devices can be inflated to create an erection and deflated at other times, offering a more natural look and feel. It has 3 parts:
Two cylinders placed in the erectile bodies of penis
A pump placed in the scrotum like a third testicle
A reservoir placed in the pelvis or abdominal wall
The system is interconnected and filled with saline (sterile salt water), providing an on-demand erection when the cylinders are filled
How does an Inflatable Penile Prosthesis Work?
Contrary to the name, Inflatable penile implants are not filled with air. When you squeeze the pump in the scrotum, fluid moves from the reservoir into the cylinders in the shaft of the penis, creating an erection.
When you press the deflate mechanism on the pump in the scrotum, the fluid moves out of the penis and back into the reservoir for a natural looking flaccid state.
The device is a closed-system and the fluid does not need to be changed or topped up.
Which is the Best Penile Implant Available Today?
Penile implants are produced by three main companies – Coloplast, Rigicon and Boston Scientific / AMS.
There are subtle differences between devices made by each company. Dr. Ross will highlight these in your consultation to ensure you select the best penile implant for your specific goals and penis type.
How do I Choose Between the Different Penile Implants?
Although it is possible to change from one implant to another, Dr Ross wants this implant to be your last. Below outlines the main differences between malleable vs inflatable penile implants:
Malleable Penile Prosthesis
Advantages
Easy to use
Does not need a reservoir or pump to be inserted
Shorter operating time
More economical
Disadvantages
Creates an erection that is more natural
Comparatively easier to hide
Inflatable Penile Prosthesis
Advantages
Penis remains slightly rigid when flaccid, though it can be concealed
Disadvantages
Requires reservoir to be placed in pelvis or abdominal wall and pump in scrotum
How is Penile Implant Surgery Performed?
The procedure can be performed using one of three main approaches: infrapubic, penoscrotal, or subcoronal - each with its own unique advantages and considerations.
Trained by global leaders that champion each of these, Dr Ross is highly experienced in all these techniques and will recommend the approach best suited to your needs and anatomy, prioritising minimal complications, a swift recovery, and the shortest possible downtime.
Assuming surgeon expertise, patients generally benefit most from the minimally-invasive infrapubic technique, which allows all components of the inflatable penile implant to be inserted through a 2.5 – 3cm incision just above the base of your penis.
Advantages of Dr Ross’ infrapubic approach:
Minimally interruption: Completed through a single 2.5 – 3cm incision, the procedure is typically day-surgery under local anaesthetic and sedation.
Minimal pain: Most patients are comfortable with paracetamol alone and rest comfortably at home following the procedure.
Minimal down time: 85% of Dr Ross’ patients are beginning to enjoy sex again 14-21 days after surgery.
No urethral catheter
No scrotal incision
Infection rates are routinely < 1%
Erectile-Tissue Sparing Technique
Where possible, Dr Ross employs a tissue-sparing technique during surgery, which preserves the healthy tissue in your erectile bodies around the implant device. This approach can offer several benefits:
Reduced Pain and Bleeding: By preserving natural tissue, recovery is typically more comfortable, with fewer complications. (Moncada, 2010)
Enhanced Size and Appearance: Keeping the tissue around the implant healthy can enhance the implant’s natural look and feel, and has been shown to preserve length and girth better (Moncada, 2010)
Improved Functionality: Preserved erectile tissue promotes better blood flow, which can enhance the sensation of your restored erections, as the same rush of blood and swelling occurs around the implant. (Zaazaa, 2019)
Head Swelling: Depending on your specific vascular anatomy, this technique helps maintain a fuller appearance of the penile head during intimacy. Since penile implants do not cause the head of the penis to become erect, preserving healthy tissue ensures that medications for erections still remain effective after the implant procedure and can be used to enhance the prosthetic erection if needed. (Zaazaa, 2021)
Fewer Post-operative Complications E.g Bleeding / haematoma, erosion of cylinder outside corpora, device malfunction. (Chang, 2023)
Complication Prevention
Complication prevention during penile implant surgery is the top priority, requiring meticulous planning and execution. Dr Ross works with a dedicated team in a specialised theatre environment designed for optimal sterility. The procedure is performed efficiently to minimise "airtime." Ensuring the implant is exposed to air for the shortest possible duration is a critical factor in infection prevention. This, combined with strict protocols that go beyond simply avoiding skin contact, significantly reduces the risk of infection and ensures the best possible outcomes for patients. For first time implant cases, our risk of infection is consistently <1% and approaches zero.

Penile implants are a great solution for men who need them. Most of these men wish they had done it sooner, thus avoiding bouncing back and forward between treatments that demonstrate little or no efficacy.
Penile implant surgery is not a last-ditch effort. The main consideration of whether to have a penile implant is this: Does the penis get hard and stay hard enough for penetrative intercourse? What do you currently need to do to ensure this happens?
Getting the stars to align often takes the spontaneity and enjoyment out of intimacy. This is common problem many men face, whether they care to admit it or not. For these men, penile implants offer a reliable solution that ensure you have a penetrating penis, whenever you want, for as long as you want, 100% of time.
Proactive consideration of a penile implant also prevents the loss of penile size caused by atrophy from years of inadequate erection. The penis is a unique organ that oxygenates itself during tumescence, as such, men can lose between .5 and 5cm’s in 14 months from the onset of impotence. Penile implant surgery stops this atrophy as the device acts as an internal tissue expander.
This being said, Dr Ross firmly believes that there is nothing better than having sex with your own penis with natural erections and penile implant surgery is reserved for people who need it. Knowledge is power when it comes to successful treatment of erectile dysfunction – knowing what treatment will work and what will not is key. As such, for men with erectile dysfunction, Dr. Ross will usually perform a quick study of the penile vascular system, called a penile duplex ultrasound. With this study, we can immediately start and expedite the algorithm to restore sexual health and function in a targeted way. It highlights which men do not need a penile implant and have the ability to restore or regenerate their natural function VS those who should consider a penile implant earlier to prevent the complications and architectural changes in the penis associated with delayed treatment.
While most ED cases are labelled broadly as vasculogenic, neurogenic or psychogenic, this overlooks a critical point of differentiation. Vasculogenic is divided into arteriogenic and veno-occlusive dysfunction. Medications, injections, and the newer regenerative options only work for arteriogenic ED. For those with veno-occlusive dysfunction or “venous leak”, these treatments rapidly lose effectiveness because the problem is not inflow.
Contrary to now disproven techniques, venous leak cannot be corrected by tying off superficial veins (venous ligation surgery). The “leak” that is picked up on ultrasound is the cumulative effect of thousands of deeper microscopic channels that are not closing effectively during erection because the erectile tissue is not expanding as it should. Veno-occlusive dysfunction is more accurately a structural problem within the erectile tissue, which results in reduced flexibility and expansion. While this can coexist with arteriogenic ED (where blood inflow is a problem), men with veno-occlusive dysfunction typically don’t have a problem getting blood out to the penis, the problem is keeping it there. This is why medications and injections can temporarily hold things at bay, but the problem ultimately progresses despite this. Once medications stop working for this type of ED, the only option is high-dose injection therapy (usually with a cock-ring) or penile implant surgery.

Yes! Many patients believe they are not candidates for penile implant surgery because they consider themselves a “high risk” for any surgery. Thankfully, this 15-30 minute procedure can be performed with any form of anaesthesia available: local with IV sedation, spinal or general. With Dr Ross, patients on anticoagulant therapy can also safely undergo penile implant procedure without stopping their therapy. This is especially important in patients who have undergone cardiac stent placement. Considering the age range of our patients who have undergone a penile prosthesis (21 to 95) and their co-morbidities (transplant, diabetics, dialysis, etc.) few patients are considered unsafe for this minimally invasive procedure.
-
In Dr Ross’ experience, he has not encountered a hobby, sport, or occupation that prevents implant patients from continuing their participation. Whether you’re passionate about high-intensity activities like cycling, swimming or martial arts, or enjoy pursuits such as yoga or weightlifting, or work in physically demanding environments, a penile prosthesis does not get in the way, nor is it at risk of injury. The implant does not set off security alarms at airports or guarded buildings. Once healed, my patients proceed with a normal active lifestyle if so desired.
The discreet nature of the device also ensures it remains unnoticed, even during intimate moments. With proper care and guidance, most men find they can return to their usual routines shortly after recovery, experiencing minimal disruption and maximum benefits. For those who need it, getting a penile implant is a transformative procedure not only restores sexual function but empowers patients to live life fully - physically, emotionally, and socially.

When inflated, an inflatable penile prosthesis provides rigidity comparable to a natural erection, giving you a penetrating penis on demand and restoring confidence and spontaneity in intimacy. Importantly, the prosthesis does not alter the sensation on the skin of the penis, a man's ability to reach orgasm, or ejaculation.
However, it’s worth noting that once a penile prosthesis is placed, the natural erection reflex—characterised by the sensation of blood rushing to the penis—may be diminished. Additionally, while the prosthesis ensures reliable rigidity of the erectile bodies (corpora cavernosa), it does not cause swelling (tumescence) of the penile head (glans).
To address this, Dr Ross uses an erectile tissue-sparing surgical approach. This technique aims to preserve the natural erection reflex, allowing many men to retain the familiar sensation of penile engorgement even after the implant. The erectile bodies are not cored out, we want to keep and maintain the health of this tissue. Depending on their baseline function, many of my patients say they can almost get hard without activating the device. Thus, the implant enhances your natural erectile function by providing dependable rigidity, while maintaining as much of the penis’s natural responsiveness as possible. In this way, men can continue to effectively use medications like Viagra and Cialis, even after penile implant surgery, to enhance the engorgement of the tissue around the implant with good effect.

Unlike a car that needs servicing, there is no reason to replace a penile implant or change the fluid unless it breaks or if a problem arises. With a correctly selected penile implant in the hands of a specialist, 80% of implants remain perfectly functional beyond 15 years. A recent study assessing the minimally invasive infrapubic approach, found that device survival was 92.5% at 7 years (the end of their follow-up period) and likely to continue at this rate (Di Pierri, 2024).
Based on long-term data, there is a difference in the overall longevity between different companies that make penile implants. This difference may be more or less relevant depending on your goals and each implant has their advantages in meeting the specific needs of any patient. Dr Ross will address this issue with you confidentially during your consultation to ensure you are matched with the best implant for your needs. Irrespective of the company, he generally says that 1 to 2% of all inflatable penile implants will fail per year, with a mechanical malfunction occurring in 5-10% of cases in the first 10 years. Failure is usually due to fluid leakage or a breakdown in device function, necessitating implant replacement surgery. Infections also require removal of the implant, followed by immediate replacement with a placeholder malleable implant (to prevent shortening) or after a healing period. The risk of post-operative infection is well below 1% for initial implant surgeries.

The most common complaint Dr Ross sees from patients seeking second opinions or revisions, beyond device failure, is related to pump placement. Sometimes the pump can ride up and be difficult to use. Other times the tubing is too long for the anatomy and coils uncomfortably in the scrotum. Counterintuitively, long scrotal tubing can also make the pump difficult to access, sometimes deflecting too far back into the perineum. Dr Ross places the pump in the midline between the testicles, toward the back of the scrotum and right at the bottom (the dependent position). Tubing length is tailored to your anatomy. The reason the scrotum pump is placed here
It’s easy to use
It can be accessed easily with either hand
It’s not or less visible from the outside. Other common complaints are undersized cylinders.
-
Any patient seeking re-operation for a failed penile implant should research with their surgeon which implant will be used to replace the implant and why. If seeking a revision for a functioning implant, patients must clearly identify their perceived implant inadequacies and set realistic expectations. Better is the enemy of good and revision surgery does come with risks. Setting proper goals and expectations is key.

There is a lot of confusing information about this on the internet. Let’s clear it up. Firstly, be careful of any treatment that offers you a longer penis. If it sounds too good to be true, it probably is!
Studies have repeatedly shown that your stretched flaccid penile length equates to your erect penile length, both with and without a penile implant. So, what you bring on the day to your procedure, is what you will take home when it comes to penis size. For this reason, Dr Ross will talk to you about what you can do in the lead up to surgery to get the best possible outcome on the day.
Oversizing the cylinders does not increase the length of your penis but it does lead to higher risk of cylinder complications. Equally, length growing cylinders do not perform the same way once inside the fixed structure that is your corpora cavernosa.
Once the right penile implant is in place, if used frequently both with my post-implant rehabilitation regime and sex, the penis will begin to grow in both length and girth. This increase is not immediate but modest changes do occur over time.
Prevention of length loss in the first place is critical. Think back to a time when had regular morning erections. During sleep men without erectile dysfunction have 5-10 erections every night. These cyclical erections ensured that your erectile tissue remained healthy and oxygenated. When you remove this, the erectile tissue becomes less oxygenated, resulting in decreased elasticity and increased scarring (fibrosis), which ultimately manifests as loss in length and girth. Since the implant is matched to the size of your corpora on the day of surgery, restored erections with the implant may appear smaller compared to your recollection of previous normal erections you’ve experienced throughout your life.
For this reason, a proactive and targeted approach based on the underlying cause of erectile dysfunction is critical to prevent dissatisfaction down the track.
The take home messages here are:
Erectile dysfunction leads to penile atrophy.
The penile implant does not make the penis shorter.
The only treatment for erectile dysfunction that stops all atrophy is the penile implant.
