  In this work, we analyze the electroweak loop corrections to the Neutralino
dark matter relic density in the framework of effective coupling. In the first
part, we comment on the generic features of the corrections and quantitative
changes to the predicted relic density. We analyze the correlation between the
characteristics of effective couplings to the nature of neutralino. Effective
couplings, however, absorb only the most dominant one loop corrections and are
not an exact calculation. In the second part, we assess the validity of
effective couplings by comparing them to the full one loop calculations in
various regions of parameter space.
