A penile fracture is a tear in the tough outer lining of the erectile chambers of the penis. It is not a broken bone, because the penis does not contain bone, but it is still a true medical emergency. The injury usually happens when an erect penis bends suddenly during sex, masturbation, or accidental pressure. Many men notice a loud pop or crack, sharp pain, fast loss of erection, swelling, bruising, or a bent “eggplant” appearance.
The right response is simple: stop sexual activity and go to the emergency room. Waiting can raise the risk of erectile dysfunction, scar tissue, curvature, painful erections, and urinary problems. Surgery is often recommended because it lets a urologist find the tear, remove trapped blood, repair the tissue, and check for urethral injury. Recovery usually takes several weeks, with sex avoided until the surgeon confirms healing.

What a Penile Fracture Is
A penile fracture happens when the erect penis bends hard enough to tear the tunica albuginea. The tunica albuginea is the strong, fibrous covering around the two erectile chambers called the corpora cavernosa. During an erection, these chambers fill with blood under pressure. The covering becomes thinner and tighter, which makes a sudden bend more likely to split it.
The word “fracture” can be confusing. There is no bone involved. The injury gets that name because the tear can happen suddenly, with a cracking or popping sound, like a fracture elsewhere in the body.
Most cases happen during sex when the penis slips out and strikes the partner’s pelvis, pubic bone, perineum, or inner thigh. It can also happen during forceful bending, masturbation, rolling over onto an erect penis, or trying to quickly hide an erection by pushing it down.
The tear allows blood to escape from the erectile chamber into surrounding tissue. That is why swelling and dark bruising can appear quickly. The penis may bend away from the tear because one side loses support. Some men also develop scrotal or lower abdominal bruising if blood spreads into nearby tissue.
A penile fracture is different from a skin cut, a frenulum tear, soreness after sex, or a minor bruise. Those problems can be painful, but they do not usually cause the classic combination of a snap, sudden pain, fast loss of erection, and major swelling. When that pattern appears, assume it is serious until a urologist proves otherwise.
Symptoms That Mean Go to the ER
The most concerning pattern is sudden injury during erection followed by a pop, pain, swelling, bruising, and immediate loss of firmness. Even if the pain fades after a few minutes, the tear may still need repair.
Common symptoms include:
- A cracking, popping, or snapping sound
- Sudden sharp penile pain
- Rapid loss of erection
- Swelling that appears quickly
- Purple, blue, or black bruising
- A bent, twisted, or “eggplant” shape
- A tender lump or gap along the shaft
- Pain with touch or movement
- Bruising spreading to the scrotum, groin, or lower abdomen
Some men do not have every symptom. A less dramatic injury can still be a fracture, especially if the penis changed shape or lost the erection right after trauma.
Urinary symptoms are especially important because they can mean the urethra was injured. The urethra is the tube that carries urine and semen through the penis. Go to emergency care right away if any of these happen after penile trauma:
- Blood at the tip of the penis
- Blood in the urine
- Trouble starting to urinate
- Inability to urinate
- Burning or severe pain while urinating
- Urine leaking from an unusual area
- Severe swelling around the underside of the penis
Blood in the urine after trauma is not something to watch at home. It needs medical evaluation, especially when paired with penile pain or swelling. A separate guide on blood in urine in men explains other causes, but after penile injury, the concern is damage to the urinary tract.
Pain alone is less specific. Penile pain can come from irritation, infection, tight pelvic floor muscles, skin injury, Peyronie’s disease, or other causes. After a clear bending injury, though, pain plus swelling or sudden erection loss should be treated as an emergency. For non-emergency patterns, common causes of penile pain can help separate irritation from injury.
What to Do Right Away
Stop sexual activity immediately and go to the emergency department. Do not try to “test” the penis by getting another erection, masturbating, having sex again, or bending it to see if it still works. More pressure can worsen bleeding or extend the tear.
A safe first response looks like this:
- Stop all sexual activity.
- Put on loose underwear or loose pants.
- Apply a cold pack wrapped in cloth for comfort if it does not delay care.
- Go to the ER, preferably one with urology coverage.
- Tell the triage nurse there was trauma to an erect penis with swelling, bruising, or a pop.
- Do not urinate if there is blood at the tip unless a clinician tells you what to do.
Avoid tight wrapping, heavy compression, massage, heat, alcohol, recreational drugs, and erectile dysfunction pills. Do not take aspirin unless a clinician recommends it, because it can worsen bleeding. If pain medicine is needed, the ER team can guide safer choices based on your bleeding risk, medications, and possible surgery.
Embarrassment is one of the biggest reasons men delay care. ER and urology teams treat genital injuries more often than most people realize. They are not there to judge what happened. A clear history helps them act faster.
Be direct about:
- When the injury happened
- Whether there was a pop or snap
- Whether the erection disappeared right away
- Where the swelling started
- Whether there is blood at the tip of the penis
- Whether you can urinate
- Any blood thinners, bleeding disorders, or major medical conditions
A partner does not have to come with you, but it can help if they saw what happened or can drive. If pain, dizziness, severe bleeding, or inability to urinate is present, avoid driving yourself.
How Doctors Diagnose It
Doctors often diagnose penile fracture from the story and exam. The classic history is specific: trauma to an erect penis, a snap or pop, sudden pain, fast loss of erection, and swelling or bruising. A urologist will examine the shaft, scrotum, urinary opening, and sometimes the lower abdomen to see how far bruising has spread.
The exam may look for:
- The side of the suspected tear
- A tender defect in the tunica
- Penile curvature or deformity
- Blood at the urethral opening
- Scrotal swelling
- Skin injury
- Signs of infection or other trauma
Testing depends on how clear the diagnosis is. If the symptoms are classic, doctors may move straight to surgery instead of waiting for imaging. Fast repair is often more important than proving every detail with a scan.
When the diagnosis is uncertain, imaging may be used. Ultrasound can sometimes find the tear and blood collection. It is quick and widely available, but small tears may be missed, especially if swelling or pain limits the exam. MRI gives clearer soft tissue detail and can be helpful when symptoms are not classic or when doctors need to locate the tear more precisely. MRI is not always available quickly, so it should not delay treatment when the diagnosis is obvious.
If urethral injury is suspected, doctors may use tests such as retrograde urethrography or cystoscopy. Retrograde urethrography uses contrast dye and X-rays to look for a leak in the urethra. Cystoscopy uses a small camera to inspect the urethra and bladder passage. These tests are more likely when there is blood at the tip, blood in urine, trouble urinating, or injury to the underside of the penis.
Not every swollen penis is a fracture. Some injuries mimic it, including rupture of a superficial vein, dartos bleeding, skin trauma, or a severe bruise without a tunica tear. That distinction matters because true fracture usually needs surgical repair, while some mimics may be treated without surgery. The problem is that it can be hard to tell at home. A cautious ER visit is better than missing the window for repair.
Emergency Treatment and Surgery
Surgical repair is the usual treatment for a confirmed penile fracture. The goal is to close the tear in the tunica albuginea, remove clotted blood, control bleeding, restore normal shape, and repair the urethra if needed.
Before surgery, the ER team may give pain medicine, check urine, order imaging if needed, and contact urology. You may be told not to eat or drink because anesthesia may be needed. Blood tests and an IV are common before an operation.
During surgery, the urologist makes an incision to reach the injured area. The exact incision depends on the location of the tear, the amount of swelling, and the surgeon’s approach. The surgeon then removes trapped blood, identifies the tear, closes it with stitches, and checks for any related injury. If the urethra is torn, it may be repaired during the same operation. A catheter may be placed to drain urine while the urethra heals or to keep the bladder empty after surgery.
Some men worry that surgery will damage erections. In general, prompt repair is done to protect erections, not harm them. Untreated tears can heal with thick scar tissue, curvature, painful erections, or erectile dysfunction. Surgery does carry risks, but delayed or conservative treatment often carries higher long-term risk when a true fracture is present.
Conservative treatment may include rest, compression, ice, anti-inflammatory medicine, and sexual abstinence. It is less favored for classic penile fracture because it does not directly close the tear or remove the clot. It may be considered only in selected cases, such as a confirmed mimic injury or a very small injury after specialist evaluation. It should not be chosen at home because the penis looks “less swollen” after a few hours.
The timing matters. Many urologists aim to repair penile fracture as soon as reasonably possible, often within the first day. A short delay for safe anesthesia, transfer to urology, or needed imaging may happen. A long delay because of shame, denial, or hope that it will heal on its own is the bigger problem.
| Situation | Likely next step | Why it matters |
|---|---|---|
| Classic pop, pain, swelling, and loss of erection | Urgent urology evaluation and usually surgery | Repair lowers the chance of scar-related curvature and erection problems |
| Unclear symptoms without classic deformity | Exam plus ultrasound or MRI if available | Imaging may separate true fracture from a vein rupture or bruise |
| Blood at the penile opening or trouble urinating | Urethral testing and possible repair | A missed urethral injury can cause strictures or urinary problems |
| Confirmed minor non-fracture injury | Specialist-guided conservative care | Some mimics heal without surgery, but they must be correctly identified |
Recovery Timeline After Repair
Recovery varies by the size of the tear, whether the urethra was involved, how quickly repair happened, and the surgeon’s instructions. Most men need several weeks before returning to sex. The surgeon’s clearance matters more than the calendar.
During the first 24 to 48 hours, pain, swelling, and bruising are expected. The penis may look worse before it looks better because bruising spreads as blood settles. Hospital stay may be short, sometimes same day or overnight, unless there was a more complex injury.
During the first week, the main goals are wound care, swelling control, pain control, and preventing strain on the repair. A catheter may remain in place if the urethra was repaired or if the surgeon wants urinary drainage during early healing. Follow instructions on showering, dressing changes, and activity. Avoid heavy lifting, cycling, sex, masturbation, and anything that causes pressure on the penis.
By weeks 2 to 4, bruising often fades and tenderness improves. Stitches may dissolve or be checked at follow-up. Some men notice tightness, mild lumps, or sensitivity around the incision. Erections may happen during sleep and can be uncomfortable. Tell the surgeon if erections are very painful, the wound opens, drainage appears, fever develops, or swelling suddenly worsens.
By weeks 4 to 8, many men are healing well enough to discuss return to sexual activity. Some surgeons recommend waiting about six weeks, while others adjust the timing based on the operation and exam. If urethral repair was needed, the timeline may be longer and may include catheter removal, urine testing, or repeat evaluation before sex.
A general recovery pattern looks like this:
| Time after repair | What may happen | What to avoid |
|---|---|---|
| First 1–2 days | Pain control, swelling, bruising, possible catheter | Sex, masturbation, alcohol, heavy activity |
| First week | Wound care, rest, follow-up planning | Pressure on the penis, cycling, lifting, tight clothing |
| Weeks 2–4 | Bruising fades, tenderness improves, erections may feel sore | Testing erections, sexual activity without clearance |
| Weeks 4–8 | Surgeon checks healing and discusses return to sex | Rough sex or positions that risk bending until fully cleared |
| After clearance | Gradual return to sex, monitoring for pain or curvature | Ignoring new bending, pain, or erection problems |
Call the surgeon or seek urgent care if you develop fever, spreading redness, foul drainage, severe pain, inability to urinate, catheter blockage, heavy bleeding, worsening swelling after initial improvement, or new numbness. Persistent penile numbness or tingling after an injury also deserves follow-up.
Possible Complications
Prompt repair lowers the risk of long-term problems, but it does not make complications impossible. The main issues are erectile dysfunction, curvature, painful erections, plaques or nodules, altered sensation, infection, and urinary problems if the urethra was involved.
Erectile dysfunction can happen after the injury itself, after delayed treatment, or from anxiety after a frightening sexual event. Some men have normal nighttime erections but lose confidence during sex. Others have weaker erections because of scarring, blood flow changes, pain, or fear of reinjury. Sudden erection changes after recovery should be discussed with a clinician. A broader guide on sudden erectile dysfunction explains other causes that may also need checking.
Curvature can happen if scar tissue forms unevenly. A mild curve that does not hurt or interfere with sex may only need monitoring. A new, painful, or worsening curve should be evaluated. Penile fracture can also lead to firm scar areas that feel like plaques. Those symptoms can overlap with Peyronie’s disease and penile curvature, although the cause and timing may be different.
Painful erections often improve as healing continues. Persistent pain may come from scar tissue, nerve irritation, infection, tight pelvic floor muscles, or anxiety-related guarding. Pain that blocks sex or continues for months deserves follow-up rather than repeated attempts to push through it.
Urethral complications are less common but important. A urethral stricture is a narrowed area of the urine tube that can form after injury or repair. Symptoms can include weak stream, spraying, straining, dribbling, urinary tract infections, or feeling unable to empty the bladder. Men with these symptoms after penile trauma should see a urologist. Related urinary symptoms, such as a weak urine stream, should not be dismissed if they started after the injury.
Emotional effects are also real. Some men avoid sex, worry about penis appearance, or feel anxious during positions linked to the injury. This can create a cycle where fear causes erection loss, which then increases fear the next time. A urologist can check the physical repair, and a sex therapist or mental health professional can help when fear, shame, or performance anxiety remains after the body has healed.
Sex After Healing and Prevention
Sex should wait until the urologist confirms that the repair has healed. Many men are advised to avoid intercourse and masturbation for several weeks, often around six weeks, but the exact timing depends on the injury. Starting too early can stress the repair and increase pain, swelling, or reinjury risk.
The first few times after clearance, go slowly. Choose positions where the penis is less likely to slip out and bend. Use enough lubrication to reduce friction. Stop if pain, sharp bending, sudden swelling, or new bruising occurs. It is better to pause early than to repeat the injury.
Penile fractures often happen when thrusting continues after the penis slips out. Risk can be reduced by slowing down during position changes, guiding the penis back in with a hand, avoiding forceful thrusting at awkward angles, and stopping when either partner feels the penis bend. Positions where the receiving partner controls depth or movement may carry more risk for some couples if motion becomes forceful or poorly aligned. That does not mean those positions are forbidden; it means control, communication, and alignment matter.
Alcohol and recreational drugs can increase risk because they reduce coordination, pain awareness, and judgment. Erectile dysfunction drugs can also contribute indirectly if they lead to prolonged or very firm erections during rough or prolonged sex. Men using ED medication should follow prescribing instructions and avoid combining these drugs with unsafe substances. Any erection lasting four hours or longer is a different emergency called priapism, which needs urgent care; it is covered separately in prolonged erection emergency treatment.
After recovery, get checked if you notice:
- Painful erections that do not keep improving
- A new curve that affects sex
- A firm plaque or lump in the shaft
- Weaker erections than before the injury
- Numbness or reduced sensation
- Blood in urine or semen
- Weak stream, spraying, or straining to urinate
- Fear of sex that does not improve with time
A good outcome is common when the injury is treated quickly. The most important step is not trying to diagnose it at home. A pop, sudden pain, swelling, and fast loss of erection after bending trauma should be treated as a urology emergency.
