Abstract: We show that oblivious transfer of bits from $A$ to $B$ can be obtained from a single instance of the same primitive from $B$ to $A$. Our reduction is perfect and shows that oblivious transfer is in fact a symmetric functionality. This solves an open problem posed by Cr\'epeau and S\'antha in 1991.
