[Beta-endorphin--physiologic role and menstrual cycle disorders].
There are three classes of endogenous opioid peptides: endorphins, enkephalins, dynorphins. Beta-endorphin is the main representative of endogenous opioid peptides. Beta-endorphin plays a role in the regulation of the normal menstrual cycle and possibly in the onset of puberty. This peptide is also involved in the pathophysiology of such menstrual disorders as: exercise-associated amenorrhoea, stress-induced amenorrhoea, weight loss related amenorrhoea and premenstrual syndrome. Probable mechanism is that alterations in the levels of beta-endorphin may change the pulsatile release of GnRH. This article reviews contemporary views on the role of beta-endorphin in the physiology and disorders of the menstrual cycle.
