Abstract: A generalization of Mazur's theorem, proved by Kamienny, states that there are 26 possibilities for the torsion subgroup of an elliptic curve over quadratic extensions of the rational numbers. We prove that if $G$ is isomorphic to one of these subgroups then the elliptic curves up to height $X$ whose torsion is isomorphic to $G$ is on the order of $X^{\frac{1}{d}}$ where $d>1$.
