Joyce relates a history of a stout man who awoke with a vigorous erection, and feeling much irritation, he scratched himself violently.

He soon bled copiously, his shirt and underlying sheets and blankets being soaked through.

On examination the penis was found swollen, and on drawing back the foreskin a small jet of blood spurted from a small rupture in the frenum.

The authors have knowledge of a case in which hemorrhage from the frenum proved fatal.
The patient, in a drunken wager, attempted to circumcise himself with a piece of tin, and bled to death before medical aid could be summoned.
It sometimes happens that the virile member is amputated by an animal bite.

Paullini and Celliez mention amputation of the penis by a dog-bite.
