Atrial natriuretic factors (ANF) may influence testicular steroidogenesis. This study was conducted to evaluate the presence of specific ANF-binding on isolated adult rat Leydig cells and the effects of ANF on testosterone production. Indirect immunofluorescence technique demonstrates that adult rat Leydig cells possess specific ANF-binding and that rAP-II strongly stimulates the testosterone production. rAP-II exerts its maximal stimulatory effect on the testosterone secretion at low doses (10(-11) M), corresponding at the physiological plasmatic concentration in the adult normal rat. High doses (10(-9)-10(-7) M) of rAP-II show a decline in the stimulatory effect on testosterone secretion. Our data suggest that rAP-II influences the testicular steroidogenesis by a receptorial mechanism; the biphasic effect of rAP-II on the testosterone production may be related to an acute receptorial desensitization phenomena.
