Abstract_ Background The intracellular signalling mechanisms that regulate ovarian follicle development are unclear however we have recently shown differences in the Akt and Erk signalling pathways in dominant compared to subordinate follicles. The aim of this study was to investigate the effects of inhibiting Akt and Erk phosphorylation on IGF- and gonadotropin- stimulated granulosa and theca cell function in vitro and on follicle development in .
