Effects of spin polarization on the structure of symmetric nuclear matter and pure neutron matter are investigated. We show that spin polarization induces a deformation of the Fermi spheres for nucleons with spins parallel and opposite to the polarization axes. This feature can be related to the structure of the one-pion exchange contribution to a realistic nucleon-nucleon interaction. While the anisotropies in the momentum distribution lower the energy of the system by a small amount, the associated variations of the single-particle energies with the angle between the polarization axis and the particle momentum are significant.
