The Prince Albert (PA) is one of the more common male genital piercings.^[1] The PA is “a ring-style piercing that extends along the underside of the glans from the urethral opening to where the glans meets the shaft of the penis.”^[2] The related “reverse Prince Albert piercing” enters through the urethra and exits through a hole pierced in the top of the glans.^[3]

While some piercers may choose to avoid the nerve bundle that runs along the center of the frenulum altogether, others will choose otherwise.^{[citation needed]} The piercing can be centered if the bearer is circumcised. Otherwise, the piercing must be done off-center because the surrounding skin needs to be able to reposition itself dynamically.^[4]
