How Does Penis Enlargement Surgery Work?

Penis enlargement surgery refers to a range of medical procedures designed to alter the appearance or dimensions of the penis. Depending on the individual's anatomy and objectives, treatment may focus on increasing visible penile length, improving girth or addressing factors that make the penis appear shorter than it actually is.

For men considering treatment, understanding how penis enlargement surgery works is essential. Different procedures involve different techniques, produce different outcomes and have their own recovery requirements and potential risks.

At Moorgate Andrology, penis enlargement treatment includes surgical options as well as non-surgical hyaluronic acid filler procedures for men seeking increased penile girth. These approaches are not interchangeable: surgery may involve altering supporting structures or transferring the patient's own fat, whereas fillers are injected beneath the penile skin.

In this guide, we explain how the main procedures work, what they can realistically achieve, how recovery is managed and what men should consider before deciding whether treatment is appropriate.

What Are the Different Types of Penis Enlargement Surgery?

There is no single operation that achieves every type of penis enlargement. Different procedures target different anatomical structures, and the most appropriate approach depends on the patient's starting anatomy, treatment objectives and medical suitability.

The main approaches include:

1. Suspensory ligament release

This procedure involves releasing the suspensory ligament that connects the penis to the pubic bone. It can allow a greater proportion of the penile shaft to hang externally, potentially improving visible flaccid length.

However, it does not create additional erectile tissue and does not necessarily increase erect penile length. There are also potential disadvantages, including changes to the angle and stability of erections.

2. Fat transfer for penile girth enhancement

Fat transfer involves taking fat from another area of the patient's body, processing it and injecting it into the penile shaft to increase circumference.

Some of the transferred fat may be reabsorbed by the body, so results can be variable. Uneven absorption, irregularities and other complications are important considerations.

3. Hyaluronic acid penile girth enhancement

Hyaluronic acid fillers provide a non-surgical option for increasing penile circumference. The filler is carefully injected beneath the penile skin to add volume around the shaft.

Unlike surgery, this approach does not involve releasing ligaments or transferring fat. Results are temporary, and the amount of enhancement depends on the individual's anatomy and treatment plan.

These procedures have different benefits, limitations and risks. A specialist assessment is important to establish which approach, if any, is appropriate for an individual patient.

How Does Suspensory Ligament Release Work?

Suspensory ligament release is a surgical procedure intended to increase the visible length of the penis, particularly when flaccid.

The suspensory ligament is a structure that connects the penis to the pubic bone and helps support it. By carefully releasing part of this ligament, the surgeon can allow a greater proportion of the penile shaft to extend externally.

What happens during the procedure?

The operation is generally performed under anaesthesia. The surgeon makes an incision in the pubic region to access the suspensory ligament and carefully releases the relevant supporting tissue. The incision is then closed, and the patient receives post-operative instructions to support healing.

In some cases, a surgeon may recommend additional measures to reduce the risk of the ligament reattaching during healing. The precise technique depends on the patient's anatomy and the surgeon's assessment.

What results can be expected?

The main potential benefit is an improvement in visible flaccid length. However, the procedure does not create new penile tissue or guarantee an increase in erect length.

Patients should also understand the potential disadvantages. Releasing the ligament can change the angle at which the penis is supported during an erection, potentially affecting stability or making penetration more difficult in some cases.

For this reason, careful patient selection and a detailed discussion of the benefits and limitations are essential before proceeding.

How Does Fat Transfer for Penile Girth Enhancement Work?

Fat transfer, sometimes called autologous fat transfer, is a surgical technique that uses the patient's own fat to increase penile circumference.

Unlike hyaluronic acid fillers, which use a manufactured gel, fat transfer involves taking fat from another part of the body and placing it beneath the skin of the penile shaft.

What happens during the procedure?

The process generally involves three stages:

1. Fat harvesting: Fat is removed from an area such as the abdomen or thighs using liposuction.
2. Fat processing: The harvested fat is prepared to separate suitable fat cells from unwanted fluid and other material.
3. Fat injection: The processed fat is carefully introduced into the penile shaft to increase girth.

The procedure requires surgical expertise and careful attention to the distribution of the transferred fat.

What results can be expected?

Fat transfer can increase penile circumference, but the final result is not entirely predictable. Some of the transferred fat is normally reabsorbed by the body, meaning the initial appearance may change as healing progresses.

Potential complications include uneven fat absorption, lumps, irregularities, asymmetry, infection and tissue damage. Further treatment may sometimes be required.

Men considering fat transfer should understand that results vary and that the procedure does not guarantee a uniform or permanent increase in girth. A specialist consultation is important to discuss whether this approach is appropriate compared with other available options.

How Does Hyaluronic Acid Penis Enlargement Treatment Work?

Hyaluronic acid penile girth enhancement is a non-surgical treatment that uses a specialised dermal filler to increase the circumference of the penis.

Hyaluronic acid is a substance naturally found in the body, where it helps retain moisture and maintain tissue volume. In penile girth enhancement, a medical-grade hyaluronic acid gel is carefully injected beneath the skin of the penile shaft to add volume.

Unlike suspensory ligament release or fat transfer, this treatment does not require an operation or the removal of tissue from another part of the body.

What happens during treatment?

The procedure generally involves several stages:

1. Initial assessment: A specialist assesses the patient's anatomy, medical history and expectations to establish whether treatment is suitable.
2. Preparation: The treatment area is cleaned and an appropriate anaesthetic approach is used to improve comfort.
3. Filler injection: Hyaluronic acid filler is carefully introduced beneath the penile skin using an appropriate injection technique.
4. Shaping and assessment: The clinician assesses the distribution of the filler to achieve an appropriate and even appearance.
5. Aftercare: The patient receives instructions about recovery, hygiene, sexual activity and any temporary restrictions.

What filler treatments does Moorgate Andrology offer?

Moorgate Andrology offers three levels of hyaluronic acid penile girth enhancement:

• Essential: An entry-level treatment option.
• Signature: A higher-level treatment option.
• Elite: A premium treatment option.

The appropriate option depends on the patient's anatomy, desired outcome and clinical assessment. The amount of filler used and the treatment plan should be individualised rather than based on a fixed volume for every patient.

How long do the results last?

Hyaluronic acid filler is gradually broken down by the body, so the results are temporary. How long the enhancement 

remains noticeable varies according to the individual, the filler used and other factors.

Potential complications include swelling, bruising, infection, uneven distribution, lumps and, rarely, serious vascular complications. Treatment should only be undertaken by an appropriately trained medical professional with a clear understanding of penile anatomy and complication management.

Hyaluronic acid filler is an alternative to surgical girth enhancement, but it is important to understand that it does not increase the underlying length of the penis

What Happens Before Penis Enlargement Surgery?

Before undergoing penis enlargement surgery, patients should have a thorough assessment to establish whether treatment is appropriate and what can realistically be achieved.

The consultation process is an important part of treatment. It allows the urologist to understand the patient's concerns, examine relevant anatomy, review medical history and explain the available procedures.

1. Initial consultation

Patients can discuss their concerns and objectives with a specialist urologist. This includes establishing whether the priority is increased visible length, greater girth or a combination of both.

2. Medical assessment

The urologist reviews relevant medical history, previous procedures, medications and any conditions that could affect surgery or healing. An examination may be required to assess penile anatomy and suitability.

3. Discussion of treatment options

The surgeon explains the procedures that may be appropriate, including their potential benefits, limitations, risks and alternatives. Patients should have a clear understanding of what surgery can and cannot achieve.

4. Understanding the risks and recovery

Before deciding to proceed, patients should understand the likely recovery requirements, restrictions on sexual activity, follow-up arrangements and possible complications.

5. Informed consent

Patients should have sufficient time to consider the information provided and ask questions before signing consent documents. Consent should be voluntary and based on a clear understanding of the proposed procedure.

At Moorgate Andrology, patients can arrange an initial video consultation with a specialist urologist to discuss their 

concerns and explore the available options before making a decision.

What Happens During Penis Enlargement Surgery?

The details of penis enlargement surgery depend on the procedure being performed. Surgical techniques for increasing visible length are different from those used for penile girth enhancement.

Before the operation, the patient undergoes the necessary pre-operative checks, and the surgical team confirms the planned procedure.

Anaesthesia

The type of anaesthesia depends on the operation, the patient's medical circumstances and the surgeon's preference. Procedures may be performed using local anaesthesia, sedation or general anaesthesia, depending on the treatment plan.

The surgical procedure

For suspensory ligament release, the surgeon accesses the suspensory ligament through an incision in the pubic region and carefully releases the relevant supporting tissue.

For fat transfer, fat is harvested from another area of the body, processed and then carefully injected into the penile shaft to increase circumference.

These are distinct procedures and are not necessarily performed together. The appropriate technique depends on the patient's anatomy and treatment objectives.

After the operation

The surgical team monitors the patient during the immediate recovery period and provides instructions about wound care, hygiene, medication, physical activity and follow-up.

Patients should not assume that the appearance immediately after surgery represents the final result. Swelling and bruising can affect the appearance during early healing, and recovery times vary according to the procedure and individual circumstances.

What Is the Recovery Process After Penis Enlargement Surgery?

Recovery following penis enlargement surgery varies depending on the procedure performed, the patient's general health and how their body heals.

It is important to follow the operating surgeon's instructions rather than rely on a fixed recovery timetable. Different procedures involve different levels of tissue disruption and have different aftercare requirements.

The initial recovery period

Swelling, bruising, tenderness and temporary changes in appearance can occur following surgery. Patients may be advised to rest, keep the treated area clean and avoid activities that could place pressure on the healing tissues.

Returning to everyday activities

The timing of a return to work, exercise and normal activities depends on the operation and individual recovery. Strenuous exercise, heavy lifting and activities that place pressure on the surgical area may need to be restricted temporarily.

Resuming sexual activity

Patients must avoid sexual activity, including masturbation, until their surgeon confirms that it is safe to resume. Returning too early may interfere with healing and increase the risk of complications.

Follow-up appointments

Post-operative review allows the clinical team to assess healing, discuss any concerns and monitor the developing result. Patients should contact their treating team if they experience increasing pain, significant swelling, spreading redness, fever, unusual discharge or other unexpected symptoms.

It is important to remember that recovery is not simply about waiting for the penis to look different. Allowing tissues to heal properly and attending recommended follow-up appointments are essential parts of treatment.

What Are the Risks and Complications of Penis Enlargement Surgery?

As with any surgical procedure, penis enlargement surgery carries potential risks and complications. These vary according to the technique used, the patient's anatomy, general health and the experience of the treating surgeon.

It is important to understand these risks before deciding whether to proceed.

General surgical risks

Potential complications associated with surgery include:

• Infection at the treatment or incision site.
• Bleeding, bruising and swelling.
• Pain or prolonged tenderness.
• Delayed wound healing or wound separation.
• Scarring or changes in skin sensation.
• An unexpected cosmetic result or the need for further treatment.

Risks associated with suspensory ligament release

Specific concerns include changes to the angle or support of erections, reduced stability during sexual activity, scarring and the possibility that the ligament may reattach during healing. The procedure does not guarantee increased erect length.

Risks associated with fat transfer

Transferred fat may be absorbed unevenly, potentially resulting in lumps, asymmetry or irregularities. Other complications can include infection, fat necrosis and tissue damage.

Risks associated with hyaluronic acid fillers

Although filler treatment is non-surgical, it is not risk-free. Potential complications include swelling, bruising, infection, uneven distribution, palpable lumps and, rarely, vascular compromise or tissue injury.

The importance of specialist assessment

The safest approach is to have an individual assessment with a suitably qualified and experienced medical professional who can explain the relevant risks and determine whether treatment is appropriate.

Patients should never feel pressured to proceed. They should have the opportunity to ask questions, understand the limitations of treatment and consider the alternatives before providing informed consent.

What Results Can Penis Enlargement Surgery Realistically Achieve?

The results of penis enlargement surgery depend on the procedure performed, the individual's anatomy and how their body responds to treatment. It is important to understand what each technique is designed to achieve and to have realistic expectations before proceeding.

Visible penile length

Suspensory ligament release may increase the amount of the penis visible outside the body, particularly when flaccid. However, it does not create additional penile tissue and does not necessarily increase erect length. The degree of visible change varies between patients.

Penile girth

Fat transfer and hyaluronic acid filler treatment are used to increase penile circumference. Both can produce an increase in girth, although the results differ.

With fat transfer, some of the transferred fat is normally reabsorbed by the body. The amount that remains can vary, so the final result may be less than the initial post-treatment appearance.

Hyaluronic acid fillers provide an increase in girth by adding volume beneath the penile skin. The result is temporary, and its duration varies between individuals and according to the treatment provided.

Individual results will vary

There is no single result that can be guaranteed for every patient. Factors such as starting anatomy, skin characteristics, treatment technique, healing and individual response can all influence the outcome.

A consultation with an experienced specialist is important to establish which treatment, if any, is appropriate. The aim should be a proportionate, natural-looking result that takes account of the patient's anatomy, expectations and the potential risks of treatment.

Who Is Suitable for Penis Enlargement Surgery?

Penis enlargement surgery is not suitable for everyone. Whether treatment is appropriate depends on a man's anatomy, general health, medical history, expectations and understanding of the potential benefits and risks.

A specialist assessment is important before any procedure is considered. This allows the clinician to examine the relevant anatomy, discuss the concerns prompting the request and establish whether a surgical or non-surgical approach is likely to be appropriate.

Factors considered during assessment include:

• General health: Medical conditions, previous surgery, medications and other factors that could affect anaesthesia, healing or the risk of complications.
• Penile anatomy: The amount of visible penile length, skin characteristics and any anatomical features that may influence the likely outcome.
• Treatment objectives: Whether the main concern relates to visible length, girth or another aspect of penile appearance.
• Realistic expectations: An understanding that procedures have limitations and cannot guarantee a particular measurement or cosmetic result.
• Psychological wellbeing: Whether concerns about penile size are causing significant distress or are associated with an unrealistic perception of normal anatomy.

Treatment may need to be delayed or considered unsuitable where there are medical concerns, active infection, healing risks or expectations that cannot reasonably be achieved. Further assessment or psychological support may sometimes be appropriate before making a decision.

The purpose of a consultation is not simply to establish which procedure a patient wants. It is to determine whether treatment is medically appropriate, explain the available options and support an informed decision.

Penis Enlargement Surgery vs Non-Surgical Treatment

Men considering penis enlargement often want to understand whether surgery or a non-surgical treatment is likely to be the better option. The answer depends on the intended outcome, individual anatomy, expectations and willingness to accept the different risks and limitations of each approach.

At Moorgate Andrology, treatment options include surgical procedures and hyaluronic acid (HA) filler treatment. These approaches work in different ways and should not be regarded as interchangeable.

Surgical penis enlargement

Surgical procedures may be considered where the objective is to alter visible penile length or increase girth using the patient's own fat.

• Suspensory ligament release: This procedure aims to increase visible penile length, particularly when the penis is flaccid. It does not create additional penile tissue or reliably increase erect length.
• Fat transfer: Fat is taken from another area of the patient's body, processed and injected beneath the penile skin to increase girth. Some transferred fat is normally reabsorbed, so the retained result varies.

Surgery involves procedural risks, recovery requirements and the possibility of an outcome that differs from the patient's expectations.

Non-surgical hyaluronic acid filler treatment

HA filler is injected beneath the penile skin to increase girth. It does not involve suspensory ligament surgery or fat harvesting, and it does not increase penile length.

The treatment is temporary because the body gradually breaks down the hyaluronic acid. Results and their duration vary between individuals. Possible complications include swelling, bruising, infection, uneven distribution, lumps and, rarely, vascular complications.

Which approach is right?

There is no universally best option. A man primarily concerned about visible flaccid length may require a different assessment from someone whose main objective is increased girth.

The most appropriate approach should be based on a specialist consultation, an assessment of anatomy and health, and a clear discussion of realistic outcomes, risks, recovery and alternatives. In some cases, the safest and most appropriate recommendation may be not to undergo enlargement treatment

Frequently Asked Questions About How Penis Enlargement Surgery Works

Does penis enlargement surgery actually work?

Penis enlargement procedures can change aspects of penile appearance, but the results depend on the technique used and the individual's anatomy. Suspensory ligament release may increase visible flaccid length, while fat transfer and hyaluronic acid fillers can increase girth. No procedure can guarantee a particular result.

Does penis enlargement surgery increase erect length?

Suspensory ligament release is primarily intended to increase visible penile length when flaccid. It does not create additional penile tissue and does not reliably increase erect length.

How is penile girth increased during surgery?

One surgical option is fat transfer, where fat is taken from another area of the body, processed and injected beneath the penile skin. Hyaluronic acid filler can also increase girth, although this is a non-surgical injectable treatment rather than an operation.

How long do the results last?

This depends on the procedure. Results from suspensory ligament release are intended to be long-lasting, although the final appearance can be affected by healing and scarring. With fat transfer, some of the transferred fat is reabsorbed, and the amount retained varies. Hyaluronic acid filler is temporary and is gradually broken down by the body.

Is penis enlargement surgery painful?

Some discomfort, swelling and bruising can occur after treatment. The level of discomfort and the recovery experience vary according to the procedure and the individual. The clinical team should explain the expected recovery and appropriate pain management before treatment.

Is penis enlargement surgery safe?

All surgical procedures carry risks, and penis enlargement is no exception. Potential complications include infection, bleeding, delayed wound healing, scarring, changes in sensation and an unsatisfactory cosmetic result. The specific risks depend on the procedure. A specialist assessment and informed consent are essential.

Can penis enlargement surgery be combined with filler treatment?

Different procedures may sometimes be considered as part of an overall treatment plan, but combining treatments is not appropriate for everyone. The timing, potential benefits and additional risks need to be assessed by the treating specialist. Patients should not assume that combining procedures will necessarily produce a better result.

How do I find out which penis enlargement procedure is suitable for me?

The best starting point is a consultation with a suitably qualified specialist who can assess your anatomy, medical history and objectives. They can explain the available options, their limitations and risks, and whether treatment is appropriate in your circumstances.
