Vagina dentata

Vagina dentata (Latin for toothed vagina) describes a folk tale in which a woman's vagina is said to contain teeth, with the associated implication that sexual intercourse might result in injury, emasculation, or castration for the man involved. The topic of "vagina dentata" may also cover a rare medical condition affecting the vagina, in which case it is more accurately termed a vaginal dermoid cyst.

Such folk stories are frequently told as cautionary tales warning of the dangers of unknown women and to discourage rape.

Erich Neumann relays one such myth in which "a fish inhabits the vagina of the Terrible Mother; the hero is the man who overcomes the Terrible Mother, breaks the teeth out of her vagina, and so makes her into a woman".

The legend also appears in the mythology of the Chaco and Guiana tribes of South America. In some versions, the hero leaves one tooth.

In Hinduism, the asura Andhaka, son of Shiva and Parvati (but not aware of it), is killed by Shiva when he tries to force the disguised Shiva into surrendering Parvati. Andhaka's son Adi, also an asura, takes the form of Parvati to seduce and kill Shiva with a toothed vagina in order to avenge Andhaka, but is also slain.

In Shintoism the Ainu legend is that a sharp-toothed demon hid inside the vagina of a young woman and emasculated two young men on their wedding nights. Consequently, the woman sought help from a blacksmith who fashioned an iron phallus to break the demon's teeth. The legendary iron phallus is considered that enshrined at the Kanayama Shrine in Kawasaki, Japan, and there the popular Festival of the Steel Phallus (かなまら祭り) is held each spring. Also, prostitutes considered that praying at that shrine protected them against sexually transmitted diseases.
