| Abstract |
Reproduction is a highly integrative function whose success depends throughout the life cycle on an appropriate balance between the hormonal status of the individual and the surrounding environment. A suitable condition will lead to gonadal development and eventually the triggering of a preovulatory surge of LH via activation and/or desinhibition of the GnRH system. Among the brain factors that have been shown to relay the information to the pituitary, the primary target organ, GnRH, monoamines, aminoacids and several other neuropeptides have been identified as the main actors controlling LH secretion. However, there is still little understanding of how the neuroendocrine brain integrates all the inputs from the peripheral organs and from the external environment. Such mechanisms involve a complex interplay mainly between gonadal steroids and metabolic hormones under the influence of environmental signals. This paper will try to address those questions by reviewing recent data from the literature and our own work with special emphasis on what we have recently learnt concerning the brain as an integrative reproductive organ. |
