The paper contains a summary of the original research on the role of catecholamines in the secretory function of the corpus luteum (CL) . Short term stimulation of receptors in the b- CL enhances ovarian progesterone and oxytocin (OT) in a few minutes , whereas the b- receptor blocking reduce the basal secretion of 20 CL ? 40 %. The process involves the b1- b2 - receptors and which, through the cell membranes luteal circumferential positively correlated with the concentration of P4 and negatively with the concentration of noradrenaline (NA ) and dopamine (DA) in the luteal tissue . CL is able to synthesize NA DA as the precursor , indicating the presence of the dopamine b- hydroxylase luteal tissue . NA also enhances the process of post- translational synthesis , and synthesis P4 OT interferes with the cytochrome P450scc and 3b- HSD . Short-term changes in local circulation in the CL under the influence of NA does not impair its function . These data indicate that CL is a major area of ​​autoregulation own actions , which may be important in the states of short-term stress, especially in pregnant females .
