Our codes do not allow Copper male to PVC female since the metal can develop corrosion inside the plastic and the pressure will split the PVC female adapter. A male adapter is the weakest fitting made, and I have to replace a broken one about once a week. The best trasition as far as strength and logevity is concerned is to use a schedule 80 TOE nipple into the female copper adapter and then a coupling to connect the rest of the PVC line to it.
