Let {BtH,t∈[0,T]} be a fractional Brownian motion with Hurst parameter H. We prove the existence and uniqueness of a strong solution for a stochastic differential equation of the form Xt=x+BtH+ ∫ 0 t b(s,Xs) d s , where b(s,x) is a bounded Borel function with linear growth in x (case H⩽ 1 2 ) or a Hölder continuous function of order strictly larger than 1−1/2H in x and than H− 1 2 in time (case H> 1 2 ).
