Here is a solution that I lifted from a previous posting (by P.J. Hinton) to
this group:
<<Graphics`ParametricPlot3D`
gr = (ParametricPlot3D[{Cos[u] Cos[v], Sin[u] Cos[v], Sin[v]},{u, 0, 2Pi,
Pi/20},{v, -Pi/2, Pi/2, Pi/10}, DisplayFunction -> Identity] /.
Polygon[x_] -> {EdgeForm[], Polygon[x]} );
Show[gr, DisplayFunction -> $DisplayFunction];
