When FSH secretion was ionophoretically induced by A23187, however, little cAMP was detected. These results support a role for calcium mobilization in the second messenger cascade underlying GnRH-induced FSH release.
IP3, DAG, and Ca are second messengers in the phosphoinositol pathway. The pathway begins with the binding of extracellular primary messengers such as epinephrine, acetylcholine, and hormones AGT, GnRH, GHRH, oxytocin, and TRH, to their respective receptors. Epinephrine binds to the α1 GTPase … See more Second messengers are intracellular signaling molecules released by the cell in response to exposure to extracellular signaling molecules—the first messengers.

Activation of the GnRHR ultimately causes the release of follicle stimulating hormone (FSH) and luteinizing hormone (LH).
