From studiosus' answer to

A 3-manifold with fundamental group isomorphic to a surface group.

a closed 3-manifold cannot have a fundamental group isomorphic to that of a closed surface of genus $\geq 2$.

What about genus 1? I wonder if there exist a closed 3-manifold with fundamental group isomorphic to the fundamental group of the 2-dimensional torus or the Klein bottle.

Thanks in advance

    Thanks again

    Actually, the proof in my answer only uses the assumption that genus is $\ge 1$. – Moishe Kohan Dec 12 '14 at 20:17
