We calculate the double-spin transverse asymmetries for the Drell-Yan lepton pair production in pp and {bar p}p collisions. We assume the transverse and the longitudinal polarization densities to be equal at a very small scale, as is suggested by confinement model results. Using a global fit for the longitudinal distributions, we find transverse asymmetries of order of 10{sup {minus}2} at most, in the accessible kinematic regions. {copyright} {ital 1997} {ital The American Physical Society}
