Paraphimosis

Paraphimosis is an uncommon medical condition in which the foreskin of a penis becomes trapped behind the glans penis, and cannot be reduced. 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.
