Androgen effects on neurosteroids and endogenous opioids - Abstract

Androgen arriving from the gonads via the circulation modulate brain function, affecting gender differentiation and sexually differentiated behavioral responses, but also the ability of the brain to process, store and retrieve sensory information. Gonadal steroids are being increasingly recognized as important factors influencing the endogenous opioid system and the neurosteroids milieu in both sexes, underlining the presence of additional hormone-related neurobiological mechanisms for gender differences of brain function. Beta-endorphin is the endogenous opiate that has received the most research attention: behavioral, analgesic, thermoregulatory and neuroendocrine properties of this peptide have been widely described and a role in the central drive of sexuality it has been recently evaluated. Furthermore, brain and plasma concentrations of neurosteroids have been found to modulate both behavioral and biochemical responses to acute and chronic stress, anxiety, depression, anaesthesia, sleep, memory and pain. These observations have suggested that the fluctuations of neurosteroids and modification of the beta-endorphin system could be involved in the development, course and prognosis of some mental disorders like depression, premenstrual dysphoria, anorexia and bulimia nervosa and Alzheimer’s disease. Though a large attention has been given to the study of estrogens role, relative attention and awareness has been focused on the activity of endogenous or exogenous androgens. Delta-5 and delta-4 androgens affect directly the endogenous beta-endorphin system and the neurosteroids milieu showing also a gender-related response. The present data, suggest additional clues in the neurobiology of gonadal steroids.
