Acute hormone secretion results in hormone levels that can vary dramatically. Episodic hormone secretion results in a cyclic pattern of hormone release. WebThe concept that different systems control episodic and surge secretion of gonadotropin-releasing hormone (GnRH) was well established by the time that GnRH was identified and formed the framework for studies of the physiological roles of GnRH, and later kisspeptin.
