A hernia does not literally develop inside the penis itself, but several types of hernia can extend into the groin, scrotum, or surrounding tissue in ways that directly involve or visibly affect the penis. The most common scenario is an inguinal hernia that descends into the scrotum and, if large enough, buries the penis beneath swollen tissue. Rarer situations include penile invagination through a scrotal defect and complications from penile implant surgery where a prosthetic reservoir herniates into the inguinal canal. Each of these conditions looks and feels different, but all of them bring hernia-related problems uncomfortably close to the penis.
How an Inguinal Hernia Reaches the Genital Area
The inguinal canal is a short passageway in the lower abdominal wall through which structures like blood vessels and the spermatic cord travel down to the scrotum. When abdominal contents push through a weakness in that canal, the result is an inguinal hernia. In many cases the bulge stays in the groin crease and is easily pushed back in. But when the hernia keeps growing, abdominal organs can slide all the way down the canal and into the scrotum, creating what surgeons call an inguinoscrotal hernia. The scrotal sac stretches to accommodate bowel, omentum, or even the bladder, and as it enlarges it can pull surrounding skin and structures with it.
In extreme cases the hernia grows so large that it extends past the midpoint of the inner thigh when the person is standing. These are classified as giant inguinoscrotal hernias, and case reports describe contents including the entire greater omentum, loops of small bowel, and even the appendix sitting inside the scrotum for years or decades.
When a Hernia Buries the Penis
One of the most distressing consequences of a large inguinoscrotal hernia is what clinicians call a buried or concealed penis. The mechanism works like this: as bowel descends into the scrotal sac, the sheer weight pulls the scrotal skin downward and outward. Meanwhile, the hernia contents compress the blood and lymphatic vessels that drain the testicle and surrounding tissue. That compression causes fluid buildup and swelling in the scrotum. The combination of a dilated, heavy scrotum and lymphedema can retract the shaft of the penis into the surrounding tissue so that it is no longer visible or functional.
A cadaveric study detailed one such progression. An indirect inguinoscrotal hernia had gone untreated, and as loops of ileum descended into the right scrotal sac, the weight stretched the skin while compressing testicular vessels. Dissection revealed both a hematoma along the lateral scrotal wall and significant fluid between the tissue layers of the tunica vaginalis, consistent with chronic lymphedema. The combined effect had pulled the penis entirely into the scrotal mass.1International Journal of Cadaveric Studies and Anatomical Variations. Diagnostic Challenges in Donor Studies: A Case of Buried Penis Secondary to Giant Inguinoscrotal Hernia and Scrotal Lymphedema – Section: Discussion
A buried penis is not just a cosmetic problem. It makes urination difficult and messy, leads to chronic skin irritation and infections in the moist folds of trapped tissue, and makes sexual intercourse physically impossible. In a prospective study of patients with bilateral giant inguinoscrotal hernias in which the penis was completely engulfed, every single patient reported poor sexual satisfaction, and over half presented specifically because their partners had refused intercourse.2PubMed Central.

A Pediatric Rarity: Penile Invagination Through the Scrotum
In a very different scenario, the penis itself can herniate through a defect in the scrotum. A reported case involved a seven-year-old boy whose flaccid penis invaginated and then became trapped in a hole in the scrotal wall after he manipulated it. The penis had been stuck for three days before presentation. Under general anesthesia, surgeons reduced the hernia and performed a circumcision to prevent recurrence.3PubMed Central. PENILE INVAGINATION COMPLICATED BY HERNIA THROUGH THE SCROTUM – CASE REPORT
This is exceedingly rare and quite different from the adult inguinoscrotal hernia picture. Rather than abdominal contents pushing into the scrotum and burying the penis, the penis itself pushes through an abnormal opening in scrotal tissue. In children, developmental defects or unusually thin scrotal walls may create that vulnerability. The key sign is a penis that cannot be brought back to its normal position, along with visible trapping at the scrotal surface. It requires prompt surgical attention to avoid compromised blood flow.
When a Penile Implant Reservoir Herniates
Men who have a three-piece inflatable penile prosthesis implanted for erectile dysfunction carry a small but real risk of a complication that brings hernias into the picture from a completely different direction. These devices include a fluid reservoir that is typically placed behind the abdominal wall near the bladder. If the reservoir migrates through a weak spot in the inguinal canal, it herniates into the groin or scrotum.
A survey of surgeons who perform these procedures found that the incidence of reservoir herniation was about 0.7 percent. When it happened, it tended to show up in the early postoperative period, often triggered by vigorous coughing or vomiting that spiked abdominal pressure. Imperfect surgical technique during placement was also implicated in some cases. The fix usually involved reopening the inguinal area, repositioning or replacing the reservoir, and repairing the defect in the abdominal wall.4PubMed. Reservoir herniation as a complication of three-piece penile prosthesis insertion
A review from a single institution cataloged six reservoir-related complications over its experience, including one herniation and one direct inguinal hernia that developed after surgery. Other reported problems ranged from erosion of the reservoir into the bladder to compression of the iliac vein.5PubMed. Review of penile prosthetic reservoir: complications and presentation of a modified reservoir placement technique For men considering or living with a penile prosthesis, awareness that a new groin bulge or device malfunction could signal reservoir herniation is useful. It is not an emergency in most cases, but it does need surgical correction.
Bladder Herniation and Urinary Symptoms
Sometimes the organ that slides into the scrotum is the bladder itself. A sliding inguinoscrotal hernia can drag part of the bladder wall down with it, and the urinary symptoms that result can be the first thing a person notices rather than a visible bulge. One case report described a man who noticed his scrotum would shrink after urinating and who had to press on his scrotum to fully empty his bladder, essentially squeezing urine out of the herniated bladder segment.6PubMed Central. Large sliding inguino-scrotal hernia of the urinary bladder – Section: Case report
Bladder herniation matters in the context of the penis because the urinary stream and voiding mechanics are affected. Men with this condition often describe a two-stage void: first a normal stream, then a pause, followed by more urine after applying manual pressure to the groin or scrotum. If undiagnosed, a herniated bladder can develop complications like recurrent urinary infections or even kidney damage from chronic incomplete emptying. Imaging and a careful physical exam are critical to identifying the bladder as part of the hernia contents before any surgical repair.
How Inguinal Hernia Repair Affects Sexual Function
Even a standard inguinal hernia that has not grown into a giant mass can interfere with sexual function. Pain, swelling, and anxiety about the bulge in the groin all contribute. The good news from clinical studies is that hernia repair tends to improve sexual function rather than harm it.
One study tracked men’s sexual function scores before and after inguinal hernia repair. Every domain except sexual desire showed significant improvement by the first month after surgery. By six months, desire had also improved, and all scores continued climbing compared to the one-month mark.7PubMed Central. Does inguinal hernia repair have an effect on sexual functions? A separate study confirmed that sexual function domains improved at three months after hernioplasty, with the total sexual score continuing to progress through nine months. Quality-of-life measures including physical function, vitality, and social activity also recovered within the first three months.8PubMed.

These findings are reassuring for men who worry that surgery near the groin could damage sexual nerves or blood supply to the penis. While temporary soreness and swelling are normal in the weeks following repair, the trajectory for most men is toward better function than they had before the operation. The initial dip in desire at one month likely reflects postoperative discomfort rather than any lasting nerve damage.
Why Giant Hernias Often Go Untreated for So Long
Giant inguinoscrotal hernias do not appear overnight. They develop over years or decades, and by the time the penis is buried and daily life is severely compromised, the hernia has often been present for a very long time. The reasons for delay are rarely medical ignorance. In the prospective study of patients with bilateral giant hernias in Nigeria and Sierra Leone, the primary reason for delayed presentation was financial constraint. Social embarrassment compounded the problem: all patients reported poor self-esteem and poor socialization because of continuous ridicule from peers.9PubMed Central. Bilateral giant inguinoscrotal Hernia: psychosocial issues and a new classification
The cadaveric study of a buried penis case similarly proposed that the donor had likely neglected to address the hernia, potentially due to lack of resources or embarrassment.10International Journal of Cadaveric Studies and Anatomical Variations. Diagnostic Challenges in Donor Studies: A Case of Buried Penis Secondary to Giant Inguinoscrotal Hernia and Scrotal Lymphedema – Section: Discussion This is a cycle that feeds on itself: the hernia causes embarrassment, which prevents the person from seeking care, which allows the hernia to grow larger and more embarrassing. By the time patients do present, the hernia has often become a surgical challenge far more complex than an early repair would have been.
Surgical Challenges With Massive Hernias
Repairing a giant inguinoscrotal hernia is not the same as fixing a small groin bulge. The central problem is that the abdominal organs have been living outside the abdomen for so long that the abdominal cavity has effectively shrunk to accommodate their absence. Surgeons call this “loss of domain.” Pushing everything back in raises pressure inside the abdomen and chest, which can compromise breathing and circulation.11PubMed Central. Giant inguinoscrotal hernia–report of a rare case with literature review
Some cases require progressive pneumoperitoneum, a technique where air is slowly injected into the abdomen over days or weeks before surgery to gradually stretch the abdominal wall and make room for the returning organs. Other approaches involve staged operations or debulking of the hernia contents. However, not every giant hernia demands such extreme measures. One case report described a hernia that extended nearly to the patient’s knees but was successfully repaired through a standard transverse inguinal incision using a tension-free mesh technique, with no need for abdominal enlargement or debulking.12PubMed Central. Simple repair of a giant inguinoscrotal hernia
Another approach used in a small series of giant inguinoscrotal hernia repairs involved a preperitoneal technique with specialized mesh placed through an inguinal incision. Nine patients with eleven giant hernias were treated this way over roughly a decade.13PubMed. Transinguinal preperitoneal repair of giant inguinoscrotal hernias using Kugel mesh The variety of techniques reflects the reality that no single approach works for every massive hernia. The surgeon has to assess how much bowel is involved, how much the abdominal cavity has shrunk, and whether the patient’s cardiopulmonary system can tolerate the pressure increase when the organs are returned.
What Recovery Looks Like After a Large Hernia Repair
After a straightforward inguinal hernia repair, most men are back to normal activity within a few weeks. But when the hernia has been large enough to bury the penis or drag the bladder into the scrotum, recovery involves more than just wound healing. The penis may need time to re-emerge as scrotal swelling resolves and lymphedema clears. Residual skin excess from years of scrotal stretching sometimes requires a separate procedure to remove. Urinary function, if the bladder was involved, may take weeks to normalize as the bladder resumes its normal position and capacity.
Sexual recovery follows a pattern the studies above describe: initial soreness gives way to progressive improvement. For men whose hernia had made intercourse impossible, the return of function can be dramatic. The nine-month timeline for continued gains in sexual scores and quality of life suggests that patience is warranted, and that a disappointing first month does not predict the long-term outcome.14PubMed.

When to Seek Help
Any new bulge in the groin or scrotum deserves a medical evaluation, even if it is painless and easily pushed back in. The earlier an inguinal hernia is identified, the simpler the repair and the lower the risk of complications like bowel incarceration, testicular damage, or the progressive burial of the penis. Specific warning signs that warrant urgent attention include a bulge that suddenly becomes hard and painful, inability to push the hernia back in, nausea or vomiting alongside groin swelling, and changes in urination pattern like the two-stage voiding described in bladder herniation cases.
For men with penile prostheses, any new lump in the groin or any change in how the device inflates or deflates should prompt a call to the urologist. A herniated reservoir is not life-threatening, but it does mean the prosthesis cannot function properly and the defect in the abdominal wall will not close on its own. And for parents who notice that a child’s penis has become trapped or retracted in an unusual way, the situation calls for emergency evaluation rather than watchful waiting, because blood flow can be compromised when tissue is incarcerated.
