or PRIAPISM, is an erection of the penis without any concomitant pain, or the consent of other parts. It is thus called, because the person in this state resembles the lewd god Priapus. Coelius Aurelianus says it is a palsy of the seminal vessels, and other nerves distributed to the parts about the penis, by the distention of which this disorder is produced. It is of the same nature as the fatyriasis. See MEDICINE, No. 372.
