摘要：

Gonadotrophin-releasing hormone (Gn-RH) mediates the hypothalamic control of pituitary gonadotrophin (Gn) secretion. During the last decade, evidence has accumulated to suggest that Gn-RH and its agonists can exert extrapituitary effects via specific tissue receptors which have been identified in many tissues such as the ovary and certain hormone-sensitive tumours.1,2 The stimulation of Gn-RH receptor suppresses Gn-dependent maturation and steroidogenesis in the ovary, and expresses the antigrowth signal in the tumours. In contrast to a correlation between the direct extrapituitary effects of Gn-RH and the presence of Gn-RH binding sites in the cells, the physiological role of the extrapituitary Gn-RH receptor is not clear.
