A comparison was made between the stimulatory effects of luteinizing hormone-releasing hormone (LHRH) and long acting luteinizing hormone-releasing hormone (l.a. LHRH) on the gonadotropin secretion of normally menstruating women. The luteinizing hormone (LH) and follicle stimulating hormone (FSH) concentrations were measured by RIA. The synthetic l.a. LHRH was found more potent than the parent hormone in terms of the magnitudes and durations of the LH and FSH responses. There was no close correlation between the initial gonadotropin values and the peak levels in normally menstruating women having basal LH and FSH values within the normal ranges.
