CRH receptors in human reproduction.

Abstract Corticotropin releasing hormone (CRH), the main peptide-mediator of stress, has been found in the female reproductive system. Herein, the role of CRH receptors in the female reproductive sysem is presented. It is clear that CRH receptors are involved in the regulation of the hypothalamic-pituitary-ovarian axis, while locally are associated with decidualization, embryonic implantation, early fetal development and triggering of parturition. Abnormal CRH signalling may contribute to obstetrical pathophysiology, such as pre-eclampsia, abnormal placenta invasion, endometrial growth retardation and preterm delivery.
