Penile Fracture Explained: Understanding the Emergency

A penile fracture is a traumatic rupture of the tunica albuginea, the fibrous tissue sheath surrounding the penis’s erectile chambers (corpora cavernosa).

This urologic emergency typically occurs from blunt force trauma to an erect penis and requires immediate medical attention to prevent long-term complications. Despite its name, it does not involve a bone.

The incidence of penile fracture is relatively low, estimated at around 1 case per 100.000 to 175.000 men in the United States annually.

This comprehensive guide will walk you through the anatomy, causes, symptoms, diagnosis, and crucial treatment steps for this serious injury, empowering you with the knowledge to act quickly and ensure the best possible outcome.

What Exactly Is a Penile Fracture?

The term “penile fracture” can be alarming and misleading.

Understanding the anatomy of the penis and what happens during this injury is the first step toward demystifying the condition and recognizing its severity.

It’s not a break in a bone, but a tear in a critical structural tissue.

It’s Not a Broken Bone: The Anatomy of an Erection

The human penis contains no bones. Its rigidity during an erection is achieved through a hydraulic process.

The main erectile bodies are two parallel cylinders called the corpora cavernosa.

A third cylinder, the corpus spongiosum, surrounds the urethra and forms the head of the penis (glans).

Each of these erectile bodies is encased in a tough, fibrous, and elastic sheath called the tunica albuginea.

During sexual arousal, blood rushes into the corpora cavernosa, causing them to expand.

The tunica albuginea stretches and becomes thin, trapping the blood under high pressure and creating a firm erection.

In a flaccid state, the tunica is about 2 mm thick, but during a full erection, it thins to as little as 0.25 mm, making it more vulnerable to injury.

The “Snap”: Understanding the Tunica Albuginea Tear

A penile fracture occurs when a sudden, forceful bending or blunt trauma is applied to the erect, blood-filled penis.

This immense pressure can exceed the tensile strength of the thinned tunica albuginea, causing it to tear or rupture. This is the “fracture”.

When the tunica albuginea tears, the high-pressure blood inside the corpora cavernosa escapes rapidly into the surrounding tissues under the penile skin.

This event is often accompanied by an audible “popping” or “snapping” sound, followed by immediate, severe pain and a rapid loss of the erection (detumescence).

The resulting internal bleeding leads to significant swelling and bruising. In some cases, the injury can also damage the corpus spongiosum or the urethra, which runs through it.

How Common Is a Penile Fracture?

Penile fracture is considered a rare urological emergency.

However, the true incidence may be underreported due to the embarrassment and social stigma associated with the injury, which can cause some individuals to delay or avoid seeking medical care.

Published data provides a range of estimates:

A study using the Nationwide Emergency Department Sample in the United States from 2010-2014 found a national incidence of 1.02 per 100.000 male subjects per year.
Other sources, including the Cleveland Clinic and StatPearls, cite an estimated incidence of 1 in 100.000 to 1 in 175.000 men.

The injury most commonly affects sexually active men, with studies noting an average age between 30 and 50 years.

Some research has also observed a higher incidence during summer months and on weekends.

What Are the Telltale Symptoms of a Penile Fracture?

The presentation of a penile fracture is typically dramatic and unmistakable.

The combination of historical context (trauma to an erect penis) and a distinct set of symptoms usually makes the diagnosis clear to a healthcare provider.

The Classic Triad: The “Pop”, Pain, and Immediate Detumescence

Most individuals who experience a penile fracture report a classic sequence of events at the moment of injury:

An Audible “Popping” or “Cracking” Sound: This is the sound of the high-tension tunica albuginea tearing. Many patients describe it as being loud enough for both them and their partner to hear.
Sudden, Severe Pain: The tear and subsequent internal bleeding cause immediate and intense pain in the penis.
Rapid Loss of Erection (Detumescence): As the blood escapes from the corpora cavernosa through the tear, the penis quickly becomes flaccid.

This combination of symptoms is a hallmark of penile fracture and a clear signal that you need to go to the emergency room immediately.

Visual Signs: The “Eggplant Deformity” and Bruising

Following the initial injury, the appearance of the penis changes rapidly and dramatically.

The blood that has escaped from the erectile chambers collects under the skin, leading to:

Severe Swelling: The penis quickly becomes swollen and enlarged.
Dark Bruising (Ecchymosis): The trapped blood causes the penile shaft to turn a dark purple, blue, or black color.
“Eggplant Deformity”: This descriptive term is used by medical professionals to characterize the appearance of a fractured penis—swollen, discolored, and often bent.
Penile Angulation: The penis will often bend or deviate to the side opposite the tear in the tunica albuginea.

If the tear also involves Buck’s fascia (a deeper layer of connective tissue), the hematoma (collection of blood) can spread to the scrotum, perineum, and lower abdomen, sometimes creating a “butterfly” pattern of bruising.

Associated Symptoms You Shouldn’t Ignore

In a significant number of cases, the injury is not limited to the tunica albuginea.

The urethra, the tube that carries urine out of the body, can also be torn.

Studies suggest that a concomitant urethral injury occurs in approximately 10-20% of penile fractures.

Signs of a potential urethral injury include:

Blood at the tip of the penis (meatus).
Blood in the urine (hematuria).
Difficulty or inability to urinate.
Pain during urination (dysuria).

Any of these symptoms, in addition to the classic signs of a fracture, reinforces the need for urgent medical evaluation.

What Causes a Penile Fracture?

A penile fracture is almost always the result of direct, blunt force trauma to an erect penis.

The rigid, blood-filled state makes it susceptible to injury from sudden bending or impact.

Sexual Intercourse: The Most Common Cause

The vast majority of penile fractures occur during sexual activity.

The injury typically happens when the erect penis accidentally slips out of the vagina or anus and is forcefully thrust against a hard surface, such as the partner’s pelvic bone or perineum (the area between the genitals and anus).

While it can happen in any position, certain sexual positions are associated with a higher risk.

A review of studies suggests that positions where the person with the penis is not in full control of the thrusting motion can be riskier. These may include:

Partner-on-top positions (e.g., “cowgirl” or “reverse cowgirl”): A sudden shift in weight or an awkward angle can cause the penis to bend forcefully.
Rear-entry positions (e.g., “doggy style”): Vigorous thrusting can lead to the penis missing the entrance and striking the perineum or pubic bone.

Inadequate lubrication can also increase friction and the likelihood of the penis slipping out, contributing to the risk of injury.

Other Causes: Masturbation, Trauma, and Cultural Practices

While less common than intercourse-related injuries, other scenarios can also lead to a penile fracture:

Aggressive Masturbation: Forceful or energetic masturbation that involves extreme bending of the erect penis can cause the tunica albuginea to tear.
Rolling Over in Bed: Accidentally rolling onto an erect penis during sleep can apply enough force to cause a fracture.
Direct Trauma: Falls onto an erect penis or accidents (like a car crash or contact sports injury) that involve a direct blow to the genitals can be a cause.
Taqaandan: This is a practice, more common in some Middle Eastern and Central Asian cultures, of forcefully bending the erect penis to achieve rapid detumescence. It is a known and significant cause of penile fractures in regions where it is practiced.

Are Some People at Higher Risk?

A new and emerging risk factor is related to the treatment of Peyronie’s disease (a condition causing curved, painful erections due to scar tissue).

Injections of an enzyme called collagenase clostridium histolyticum (CCH) are used to break down the plaque.

This treatment, however, can weaken the tunica albuginea, increasing the risk of a fracture or rupture, even with less force.

The reported incidence of penile fracture after CCH treatment ranges from 0.5% to 4.9%.

How Do Doctors Diagnose a Penile Fracture?

In most cases, a penile fracture is a clinical diagnosis.

This means a doctor, typically a urologist in an emergency department, can confidently diagnose the condition based on your story and a physical examination alone. However, imaging may be used in specific situations.

The Importance of Clinical History and Physical Exam

The diagnosis starts with you describing what happened.

The classic history of an audible “pop” during trauma to an erect penis, followed by immediate pain and loss of erection, is highly indicative of a fracture.

According to the American Urological Association (AUA) Urotrauma Guidelines, clinicians must suspect penile fracture when a patient presents with penile ecchymosis, swelling, pain, a cracking or snapping sound during intercourse or manipulation, and immediate detumescence.

The physical exam will then confirm the suspicion. The presence of the “eggplant deformity”—a swollen, bruised, and potentially deviated penis—is the key physical finding.

The doctor will gently examine the penis to assess the extent of the swelling and locate the likely site of the tear, which often presents as a palpable defect or clot.

When is Imaging Necessary?

The AUA guidelines state that for patients with clear signs and symptoms, immediate surgical exploration is the standard of care, and imaging is not always required as it can delay definitive treatment.

However, imaging becomes valuable in equivocal cases, where the history or physical exam is not typical.

For example, if there was no audible pop, the pain is mild, or the swelling is minimal, an imaging study can help differentiate a true penile fracture from a less severe injury, such as a ruptured superficial dorsal vein or a simple hematoma.

Preventing an unnecessary surgery is as important as not delaying a necessary one.

Comparing Imaging Modalities: Ultrasound vs. MRI

When imaging is needed, ultrasound and MRI are the two primary modalities used. Each has its own set of advantages and disadvantages.

Imaging Modality	Advantages	Disadvantages
Penile Ultrasound	Readily available and quick; Inexpensive; Non-invasive; Can show a hypoechoic (dark) breach in the tunica albuginea	Highly operator-dependent, requires specific expertise; Significant swelling and pain can make the exam difficult; Large hematomas can obscure the view of the tear
Magnetic Resonance Imaging (MRI)	Excellent soft tissue detail; Highly accurate in detecting and localizing the tear; Can clearly show the extent of the hematoma; Not operator-dependent	Less available, especially in emergency settings; More expensive and time-consuming; Can delay definitive surgical repair

Studies have shown MRI to have very high sensitivity (approaching 100%) for detecting a tunical tear, making it the most accurate imaging test.

It is often considered the best choice for clarifying an uncertain diagnosis.

Checking for Urethral Injury

If there is any suspicion of a urethral injury (e.g., blood at the meatus, inability to urinate), a specific evaluation is mandatory.

This is typically done with a retrograde urethrogram (RUG), where a contrast dye is injected into the urethra and an X-ray is taken to see if any dye leaks out, indicating a tear.

Alternatively, the urologist may perform a cystoscopy (inserting a small camera into the urethra) in the operating room just before the repair to directly visualize any injury.

What Is the Treatment for a Penile Fracture?

The consensus among urological experts and major guidelines, including those from the American Urological Association (AUA) and the European Association of Urology (EAU), is clear: prompt surgical repair is the gold standard treatment for penile fracture.

Why is Immediate Surgery the Gold Standard?

Historically, penile fractures were sometimes managed conservatively with ice packs, compression bandages, and anti-inflammatory drugs.

However, this approach has been largely abandoned due to unacceptably high rates of long-term complications.

A meta-analysis reviewing outcomes found that immediate surgical repair is associated with significantly lower rates of erectile dysfunction (ED) compared to both delayed surgery and conservative management.

The incidence of ED after immediate surgery was found to be around 6.6-16.5%, whereas with conservative management, it skyrocketed to 45.5-52.9%.

Immediate surgery allows the surgeon to evacuate the hematoma, accurately identify and repair the tear in the tunica albuginea, and address any associated urethral injury.

This leads to better healing, less scar tissue formation, and a higher likelihood of preserving normal erectile and urinary function.

Most experts recommend surgery within 24-48 hours of the injury for the best outcomes.

The Surgical Procedure: A Step-by-Step Overview

Penile fracture repair is performed by a urologist under general or spinal anesthesia.

The goal is to restore the normal anatomy of the penis.

Incision: The surgeon makes an incision to access the site of the injury. The most common approach is a circumferential subcoronal incision, made just below the head of the penis. This allows the penile skin to be pulled back (“degloved”), providing excellent exposure of the entire shaft to find all injuries. In some cases, a direct incision over the suspected tear or a penoscrotal incision (at the base of the penis) may be used.
Hematoma Evacuation: Once the deeper layers are exposed, the surgeon will drain the large collection of clotted blood (hematoma) that has formed. This is crucial for visualizing the underlying structures.
Identifying the Tear: With the hematoma cleared, the tear in the white, fibrous tunica albuginea becomes visible. The surgeon will inspect the entire corpora cavernosa to ensure no other tears are missed.
Repairing the Tunica: The edges of the tear are brought together and meticulously sutured. Strong, absorbable sutures are typically used to close the defect in a watertight fashion.
Urethral Assessment and Repair: The urethra is carefully inspected. If a tear is found, it is repaired with very fine, absorbable sutures over a temporary urinary catheter (Foley catheter).
Closure: After ensuring there is no further bleeding, the layers of tissue and skin are closed. A light compressive dressing is applied.
No Tunical Tear: If imaging (like an MRI) definitively rules out a tear in the tunica albuginea, and the injury is confirmed to be a superficial hematoma or vein rupture, surgery is not necessary.
Fracture after CCH Injections: For penile fractures that occur after collagenase injections for Peyronie’s disease, some experts recommend conservative management if the urethra is not injured. The reasoning is that the enzyme has already weakened the tissue, and surgery may not be as effective.

What Does Recovery After Penile Fracture Surgery Look Like?

Recovery from penile fracture surgery is a gradual process that requires patience and adherence to your doctor’s instructions.

The primary goals are to allow the tissues to heal properly and to slowly return to normal function.

The First Few Weeks: Managing Pain and Swelling

The initial postoperative period will involve managing discomfort and significant swelling.

Weeks 1-2: Pain and swelling are most pronounced during this time but should slowly begin to decrease. Your doctor will prescribe pain relievers. Applying ice packs (wrapped in a cloth) to the area for short periods can help reduce swelling. You will need to keep the incision site clean and dry.
Weeks 2-4: Swelling continues to subside. Most people can resume light daily activities and return to a desk job. However, strenuous physical activity, heavy lifting, and any form of sexual activity are strictly prohibited.

The Road Back: A Recovery Timeline

Full healing takes time, and everyone’s timeline is slightly different. However, a general guide is as follows:

0-2 Weeks: Hospital stay (1-3 days). Focus on rest, pain control, and managing swelling. Follow-up appointment to check the incision.
2-6 Weeks: Gradual return to non-strenuous activities. Continue to avoid any activity that puts pressure on the penis. Swelling and bruising should be significantly improved by the end of this period.
6+ Weeks: This is the most common milestone for when doctors clear patients to resume sexual activity. However, it is absolutely critical to get your doctor’s approval before doing so.
3-6 Months: While sexual activity may be possible, full healing, including the resolution of any minor discomfort or internal scarring, can take up to six months or even longer. Erectile function may continue to improve during this time.

When Can You Resume Sexual Activity?

The most common recommendation is to abstain from all sexual activity, including intercourse and masturbation, for a minimum of 6 weeks after surgery.

Attempting sexual activity too early can disrupt the healing suture line, cause re-injury, and lead to poor long-term outcomes.

Your urologist will assess your healing at your follow-up appointments and give you the green light when it is safe to proceed.

When you do resume activity, it’s wise to be gentle at first and use ample lubrication.

Follow-Up Care and Monitoring

You will have several follow-up appointments with your urologist to monitor your healing.

They will check the incision, assess for any signs of infection, and ask about your urinary and erectile function.

In some cases, a follow-up ultrasound may be performed to assess blood flow and the integrity of the surgical repair.

What Are the Potential Long-Term Complications?

With prompt and proper surgical repair, the prognosis for penile fracture is excellent, with over 90% of men regaining the ability to have satisfactory erections.

However, complications can still occur, either from the initial injury itself or the surgery.

The risk of these complications is significantly higher in cases with delayed treatment or those managed conservatively.

Erectile Dysfunction (ED): The Biggest Concern

The most feared complication is long-term erectile dysfunction. ED after a penile fracture can result from several mechanisms:

Veno-occlusive dysfunction: Scar tissue from the injury can prevent the veins from compressing properly, allowing blood to leak out of the penis and making it difficult to maintain an erection.
Arterial damage: Though less common, damage to the arteries that supply blood to the penis can impair the ability to get an erection.
Nerve damage: Injury to the nerves responsible for sensation and erection can affect function.
Psychological factors: Anxiety, fear of re-injury, and trauma can have a powerful negative impact on erectile function.

As noted earlier, the risk of ED is dramatically lower with immediate surgery (around 10-15%) compared to conservative management (up to 50% or more).

Physical Complications: Curvature, Scar Tissue, and Pain

Other potential physical sequelae include:

Penile Curvature or Angulation: As the tear heals, scar tissue (plaque) can form. If this scar tissue is not elastic, it can cause the penis to bend or curve during an erection, a condition similar to Peyronie’s disease.
Palpable Nodules or Plaques: You may be able to feel a hard lump or scar at the site of the repair.
Painful Erections: Scar tissue can cause pain or discomfort when the penis becomes erect.
Loss of Penile Length: Significant scarring can sometimes lead to a slight shortening of the penis.
Urethral Stricture: If the urethra was injured, scarring during the healing process can cause a narrowing of the urethra, leading to a weak urinary stream or other voiding problems.
Infection: As with any surgery, there is a small risk of a wound infection.

Psychological Impact: Anxiety and Fear of Re-injury

The physical trauma of a penile fracture is often accompanied by significant psychological distress.

It’s very common for men to experience performance anxiety, fear of engaging in sexual activity, and concern about causing another injury.

This can create a vicious cycle where anxiety itself contributes to erectile difficulties. If you experience these feelings, it is important to talk about them.

Speaking with your partner, your urologist, or a licensed therapist or sex counselor can be incredibly helpful in overcoming the psychological hurdles to a healthy sexual recovery.

How Can You Prevent a Penile Fracture?

While accidents can happen, taking some precautions can significantly reduce the risk of this traumatic injury.

Prevention largely revolves around awareness and safe practices during sexual activity and other situations involving an erect penis.

Safe Sexual Practices

Use Ample Lubrication: Adequate lubrication is key. It reduces friction and makes it less likely for the penis to accidentally slip out of the vagina or anus during intercourse.
Be Cautious with Vigorous or “Rough” Sex: While passion is great, be mindful of the forces at play. Avoid overly aggressive or uncontrolled thrusting.
Communicate with Your Partner: Especially when changing positions or if you feel you are in an awkward or unstable position, communication is crucial.
Take Care During Position Changes: Manually guide the penis when changing positions to ensure it enters correctly and doesn’t strike the perineum or pubic bone.
Be Mindful in Higher-Risk Positions: If your partner is on top or you are in a rear-entry position, pay extra attention to the angle and force of movement.

Avoiding Other Risky Behaviors

Don’t Forcefully Bend an Erect Penis: Avoid practices like “taqaandan” or any other forceful manipulation intended to make an erection go away.
Be Careful in Bed: Be aware of your surroundings, especially when sleeping with an erection, to avoid rolling over on it or hitting it against a bedpost.
Avoid Forcing an Erection into Tight Clothing: This can cause an unnatural and forceful bend.

Frequently Asked Questions (FAQ)

1 – Can a penile fracture heal on its own?

No. While the body will try to heal, conservative (non-surgical) management leads to very high rates of complications like permanent erectile dysfunction, painful erections, and severe penile curvature. Immediate surgery is the standard of care for the best outcome.

2 – Is a penile fracture always painful?

Yes, a true penile fracture causes sudden and severe pain at the moment of injury. The pain is a direct result of the tear in the tunica albuginea and the rapid internal bleeding and swelling that follows.

3 – Can you still get an erection with a penile fracture?

No. The injury causes an immediate loss of the erection (detumescence) because the tear in the tunica albuginea allows the trapped blood to escape. You will be unable to get or maintain an erection until the injury is surgically repaired and has healed.

4 – What is the success rate of penile fracture surgery?

The success rate is very high when performed promptly. Over 90% of patients who undergo immediate surgical repair regain full or near-full erectile function and have a good long-term prognosis with a low rate of complications.

5 – Will my penis look different after surgery?

After the initial swelling and bruising resolve, which can take several weeks, the penis should return to a normal appearance. There will be a fine scar from the incision, often hidden in the circumcised line, which typically fades over time.

6 – How long does the surgery take?

The surgery itself is relatively straightforward for an experienced urologist and typically takes about one to two hours, depending on the complexity of the tear and whether there is an associated urethral injury that also needs repair.

7 – Is it possible to fracture a flaccid (soft) penis?

No. A penile fracture, by definition, is a rupture of the stretched and thinned tunica albuginea of an erect penis. A flaccid penis is soft and its tunica is thick and relaxed, so it will bend without tearing under force.

8 – Does a penile fracture affect fertility?

A penile fracture itself does not directly damage the testicles or sperm production. However, if the injury leads to severe, long-term erectile dysfunction that prevents intercourse, it can indirectly affect the ability to conceive naturally. This is another reason why proper treatment is vital.

Conclusion

A penile fracture is a serious and frightening urologic emergency, but it is treatable.

The key takeaway is that time is critical. The classic signs—an audible “pop” during trauma to an erect penis, immediate severe pain, and rapid loss of erection—are your body’s alarm bells.

Do not “wait and see” or let embarrassment prevent you from seeking help.

Going to the emergency room immediately and undergoing prompt surgical repair provides the best possible chance for a full recovery, preserving both sexual and urinary function for the long term.

While the recovery process requires patience and a temporary break from sexual activity, the vast majority of men return to a healthy and satisfying sex life.

If you believe you have experienced a penile fracture, your only next step should be to get to a hospital. Find Emergency Care Near You
