Pituitary function following treatment with reproductive toxins.

Appropriate regulation of reproductive processes are dependent upon the integrity of pituitary function. In this selected review, we evaluate the evidence that certain environmental compounds exert their effect on reproductive function via a direct action on the pituitary gland. We also discuss examples of changes in pituitary hormone secretion that occur in response to changes in neuronal or gonadal control of the pituitary. A limited number of studies suggest that measures of pituitary hormone secretion provide an early and sensitive measure of a compound's potential effects on the reproductive system. However, the most striking aspect of this area is the sparse and inconsistent information describing pituitary function following exposure to environmental pollutants.
