Observed distribution (top) and analytical reconstruction (middle) of the tripartite relationship among calculated pulsatile LH secretion rates, serum ganirelix (GRX) concentrations, and age in 24 healthy men. A 3-parameter exponential model was used to represent the GRX-LH inhibitory interface. Estimated inhibitory functions projected to ages 20 and 80 yr and age-dependent linear increase in inhibitory sensitivity (bottom).
