What is "paraphimosis"

Paraphimosis \Par`a*phi*mo"sis\, n. [NL., fr. Gr. ?; ? beyond + ? to muzzle.] (Med.) A condition in which the prepuce, after being retracted behind the glans penis, is constricted there, and can not be brought forward into place again.

n. A medical condition where the foreskin becomes trapped behind the glans.

Paraphimosis ( or ) is an uncommon medical condition in which the foreskin of an uncircumcised penis becomes trapped behind the glans penis, and cannot be reduced (pulled back to its normal flaccid position covering the glans). If this condition persists for several hours or there is any sign of a lack of blood flow, paraphimosis should be treated as a medical emergency, as it can result in gangrene.
