When one hormone is needed for a second hormone to produce an effect, it is called permissive. This means that the first hormone enables or enhances the action of the second hormone, but does not directly participate in the effect. An example of this is the relationship between thyroid hormone and growth hormone. Thyroid hormone is permissive for growth hormone, meaning that it sets the stage for growth hormone to act on tissues and promote growth. Without thyroid hormone, growth hormone would not be as effective.
