since it is generally held that a lh pulse is occasioned by , and therefore reflects , a discharge of hypothalamic gonadotropin-releasing hormone , it may be proposed that in the rhesus monkey , the testes impose a decisive retardation on the neural mechanism that governs the timing of intermittent gonadotropin-releasing hormone secretion , and that this modulation of the hypophysiotropic oscillator by the gonad is mediated by testicular t secretion .
