In vertebrates, the hypothalamus, located at the base if the brain, plays a central role in integrating the endocrine and nervous systems. The hypothalamus receives information from nerves throughout the body and the brain. (Mousa and Mousa, 2003) In response, the hypothalamus initiates endocrine signalling appropriate to environmental conditions. In many vertebrates’ nerve signals from the brain pass information to the hypothalamus about seasonal changes, therefore the hypothalamus regulates the release of reproductive hormones, which are required during breeding seasons.

Blotched blue-tongue can have from one up to fifteen live young, which in temperate regions, parturition usually is summer or early autumn. These temperate zone blue tongues complete vitellogenesis, ovulation, gestation and parturition all in the time frame of one year. Mating season occurs in October-November where males are aggressive towards, not only one another, female’s as well. Male blotched blue-tongues do not show any loyalty to any particular female, and the mother does all the caring for the
