When this happens, the thyroid gland is no longer under pituitary control. The amount of hormone it produces is dependent on levels of TSI. TSI are the direct cause of hyperthyroidism in Gravesâ disease and various immune system chemicals known as cytokines also contribute to the symptoms that occur in this disorder.
Iguanas are reptiles and nearly all reptiles lay eggs. There are some reptiles that do not lay eggs, but they are very rare. Female iguanas usually lay a clutch of eggs every year once they're mature. If there is no male iguana, she will still lay eggs, but they won't be fertile.
Once your iguana has laid her eggs, you can remove the eggs and nesting box and discard the eggs. It's a good practice to freeze any eggs overnight before discarding to prevent any chance of future hatching in a landfill. Iguanas do not have maternal instincts and do not care for their eggs or young.
