  We address the propagation of twin-beam of radiation through Gaussian
phase-sensitive channels, i.e. noisy channels with squeezed fluctuations. We
find that squeezing the environment always reduces the survival time of
entanglement in comparison to the case of simple dissipation and thermal noise.
We also show that the survival time is further reduced if the squeezing phase
of the fluctuations is different from the twin-beam phase.
