Eversion Typical eversion of iguana hemipene seen when the iguana defecates, deposites seminal plugs or other seminal discharge, or he just decides to flash his keeper. A prolapse is the eversion of tissue into an area where it should not be.

Reptiles are like birds in that they have a single chamber into which feces and urates are deposited before being voided. This chamber is called the cloaca and is found just inside the vent.
