Possible priming effect of luteinizing hormone releasing hormone on the anterior pituitary gland in the Japanese quail and the stimulation of secretion of follicle-stimulating hormone.
After the i.m. injection of 10 micrograms synthetic LH releasing hormone (LH-RH) into Japanese quail the levels of LH and FSH in plasma rose significantly within 2 min. The increased level of LH declined rapidly but that of FSH was maintained for the duration of the experiment. To determine whether the anterior pituitary gland is primed by LH-RH a double injection schedule was adopted. It would appear that, while endogenous LH-RH may prime the avian pituitary gland slightly, synthetic LH-RH is ineffective.
