it is concluded that : ( 1 ) tgf beta directly stimulates inhibin production by rat granulosa cells and the combined effect with fsh was largely additive , ( 2 ) the inhibitory effect of egf on fsh-induced inhibin production was enhanced by tgf beta , ( 3 ) individual members of the tgf beta/inhibin gene family regulate ovarian function , not only by direct action on follicle cells but also indirectly by influencing the production rate of other members of that family .
