If the Wolf-Rayet stars are produced by the evolution of massive stars with mass loss (Paczynski 1967, Conti 1976) from 0 stars to WN stars and thereafter to WC stars, then we may expect to observe a correlation of decreasing mean masses in the same sense as the evolution.Information about the masses of TO stars are obtained from studies of binary systems with WR components. Table 1 presents the today available data for the WN type stars.
