Background: Gonadotropin Releasing Hormone (GnRH) is a key element in sexual maturation and regulation of the reproductive cycle in the human organism. GnRH interacts with the pituitary cells through the activation of the Gonadotropin Releasing Hormone Receptors (GnRHR). Any impairments/ dysfunctions of the GnRH-GnRHR complex lead to the development of various cancer types and disorders. Furthermore, the identification of GnRHR as a potential drug target has led to the development of agonist and antagonist molecules implemented in various treatment protocols. The development of these drugs was based on the information derived from functional studies of GnRH and GnRHR.

Objective: This review aims at shedding light in the versatile function of GnRH and GnRH receptor and offers an apprehensive summary regarding the development and function of different agonists, antagonists and non-peptide GnRH analogues.

Conclusion: The information derived from these studies can enhance our understanding of the GnRH-GnRHR versatile nature and offer valuable insight for the design of new more potent molecules.
