There is recent mention made of a method of preventing masturbation by a cage fastened over the genitals by straps and locks.

In cases of children the key was to be kept by the parents, but in adults to be put in some part of the house remote from the sleeping apartment, the theory being that the desire would leave before the key could be obtained.
Among some peoples the urethra was slit up as a means of preventing conception, making a meatus near the base of the penis.

Herodotus remarks that the women of a certain portion of Egypt stood up while they urinated, while the men squatted.

Investigation has shown that the women were obliged to stand up on account of elongated nymphae and labia, while the men sought a sitting posture on account of the termination of the urethra being on the inferior side of the base of the penis, artificially formed there in order to prevent conception.

In the Australian Medical Gazette, May, 1883, there is an account of some of the methods of the Central Australians of preventing conception.
