  The excess of low invariant mass dilepton yield in heavy ion collisions
arising from reduction in the rho meson mass at finite temperatures is
partially suppressed because of the effect on the width of the rho meson
induced by Bose enhancement, essentially due to emission of pions in a medium
of the pion gas in the central rapidity region. The sensitivity of the effect
on the initial temperature of the hadronic phase is also examined.
