What Is a Pearl in Jail? Risks, Rules, and Removal

In jail, a “pearl” is a small bead or hard object that an inmate has permanently inserted under the skin of the penis as a body modification. The practice is called pearling or genital beading, and it shows up across American correctional facilities. Some online sources claim “pearl” is slang for a respected or wise inmate, but that usage has no documented basis in prison slang references or academic literature. In real conversations about jail life, the body modification is what people mean.

What Pearling Is and Why Inmates Do It

The procedure involves a small incision on the shaft of the penis, usually along the top where the skin is easiest to work with, and a bead placed beneath the skin. Once the cut heals, the bead stays embedded permanently, leaving a raised bump.¹

The stated reason is almost always physical stimulation for a sexual partner. Beyond that, pearls work as a visible marker of time served and toughness, and in some groups the number a person carries is treated as a form of status.² The best-known cultural link is to the Japanese Yakuza, where each bead was said to represent a year in prison, but in American facilities that symbolism has mostly faded. Inmates today are generally motivated by sexual enhancement or peer pressure.

How It’s Done Behind Bars

Done properly, pearling would involve sterile instruments, anesthesia, and medical-grade implants like titanium or surgical silicone. Prison allows none of that. Inmates perform the procedure on themselves or on each other with whatever is available.

Documented cases describe razor blades or sharpened plastic used to make the cut, with the implant itself made from pieces of dominoes, rosary beads, melted plastic rolled into balls, or fragments of other items. One published case involved an inmate who tried to push a domino fragment through a puncture wound made with a ballpoint pen.³ In the case literature, a brand-new razor blade counts as the clean option.¹ No anesthesia. No sterile field. No infection control.

The Health Risks

The medical literature on pearling complications is grim. Published case series consistently document infections, abscesses, swelling, and chronic pain. These are not rare worst-case outcomes; they are what emergency departments see when inmates finally present for care.⁴

Infection and abscesses. Non-sterile conditions make infection nearly inevitable. Case reports describe pus drainage, foul-smelling wounds, and infections that required emergency surgery.
Tissue damage. An implant placed too deep can injure arteries, nerves, and internal structures. An implant on the underside risks damage to the urethra.
Erectile dysfunction. Damage to the tunica albuginea, the tissue that enables erections, can cause permanent impotence or abnormal curvature similar to a penile fracture.
Implant migration. Beads shift under the skin over time, causing pain, redness, and sometimes partial breakthrough of the skin surface.
Bloodborne disease. Sharing cutting instruments or performing the procedure on someone else creates direct blood-to-blood contact, with risk of HIV, hepatitis C, and other viruses.⁵

One documented case involved an inmate who tried to insert a domino fragment and arrived at the hospital with heavy bleeding, significant swelling, and a visible laceration across the shaft. Another developed a chronic draining infection that would not heal. In the most severe published case, a man who tried to remove his own implant with a razor blade developed skin necrosis so extensive that surgeons had to remove the entire foreskin and much of the shaft skin to save the organ.⁶

Long-term complications of subcutaneous penile implants remain understudied, which means problems can surface years later that medical science has not yet fully characterized.⁴

Prison Discipline for Getting Pearled

In the federal Bureau of Prisons system, pearling falls under the prohibited act of “tattooing or self-mutilation,” a high-severity offense coded as 228. Getting caught can mean up to six months in disciplinary segregation, loss of good conduct time credits (up to 50% or 60 days of available credit, whichever is less), forfeiture of earned First Step Act time credits, loss of privileges like visitation and commissary, and monetary fines.⁷

The cutting instruments used in the procedure can also be treated as contraband. Under federal law, possessing any object that threatens the order, discipline, or security of a prison carries a potential sentence of up to six additional months, and that sentence runs consecutively, added to whatever time the inmate is already serving.⁸

State facilities have their own disciplinary codes, but most treat self-inflicted body modifications the same way: as a security-level infraction that can cost an inmate privileges and push back a release date.

Safe Removal

Medical professionals strongly recommend that anyone with pearl implants seek removal from trained medical personnel rather than attempt it alone. The published cases where inmates cut out their own implants produced some of the worst outcomes in the literature, including uncontrolled bleeding, severe infection, and tissue death that required reconstructive surgery.⁶

In a clinical setting, removal is usually a minor outpatient procedure under local anesthesia. The doctor makes a small incision, extracts the implant, and closes the wound under sterile conditions. When infection or an abscess is present, treatment typically adds antibiotics, wound care, and sometimes a urinary catheter to keep the healing area clean. The more implants a person has and the longer they have been in place, the more complex removal becomes, especially if the beads have migrated or the surrounding tissue has scarred.

If you or someone you know has pearl implants and is experiencing pain, swelling, drainage, or any sign of infection, seek medical attention immediately rather than waiting for a release date or trying to handle it alone.
