Abstract:
A nonlinear dynamical model for the pulsatile secretion of thehypothalamo-pituitary-gonad axis in human male is proposed and chaoticsolutions are obtained. We investigate the bifurcation character of thesolution and calculate the Lyapunov exponents. Some deductions of thismodel are obtained and compared with experimental results. All the resultsshow that the model is a quite reasonable one.
