It is a simple test and relatively inexpensive to have him checked for live sperm. Some are sterile from birth, others produce to 14-15 years. Most seem to start shooting blanks about 10-12 years old. If pups from this female is critical at this point in time, checking the male will let you know in time to select another male if this one cannot produce any longer.
