Penis captivus

Penis captivus is a supposed occurrence during human sexual intercourse when the muscles in the vagina clamp down on the penis much more firmly than usual, making it impossible for the penis to be withdrawn from the vagina. According to a 1979 article in the British Medical Journal, this condition was unknown in the twentieth century,[1] but a subsequent letter to the same journal reported an apparent case of penis captivus in 1947.[2] Penis captivus should not be confused with vaginismus, though a relation between the supposed event of penis captivus and the occurrence of vaginismus is assumed in the existing descriptions.

The "medical man named Davis, not otherwise identified," whose account Kräupl Taylor cites in the fifth paragraph is actually Sir William Osler's fictitious surgeon 'E.Y. Davis'.
