Egg-binding: A Threat to Reptiles

Egg-binding occurs when a female cannot pass the mature eggs formed in her reproductive system. It is also called dystoica and egg retention and is common in several reptile species including iguanas, snakes, and turtles. One survey conducted that nearly 10% of the reptile population is affected by egg-binding. It happens most frequently in snakes and iguanas.

Complications that can arise from egg-binding include:

• Death of the young or eggs
• Peritonitis
• Inflammation and scarring of the reproductive tract. This leads to decreased fertility in the future
• Death of the female

Causes of Egg-Binding

The condition of the female, nesting area, and eggs themselves could all contribute to egg-binding. If the female has an anatomical defect that is obstructive, it would be physically impossible for the egg to pass. A female who has poor muscle tone due to lack of exercise may be too exhausted to lay the last egg or not be able to do the repeated contractions necessary to clear the reproductive tract of the egg.

The nesting site needs to be the correct depth and selection of substrate for the species. Wrong conditions will deter the female from laying the eggs. The eggs themselves can also play a role. If the egg is overly large or malformed, or if it is not positioned correctly, is broken, or joined to other eggs it will be almost impossible to pass.
