We deduce the relation between the critical temperature associated to the
U(1) symmetry breaking of scalar fields with one--loop correction potential
immersed in a thermal bath, and the condensation temperature of the
aforementioned system in the thermodynamic limit, within the semiclassical
approximation for a weakly interacting bosonic gas with a positive coupling
constant. Additionally, we show that the shift in the condensation temperature
caused by the coupling constant is independent of the thermal bath.
