In my experience, and I know with many of my peers, the major inhibiting factor in the successful treatment of male disorders is treatment compliance.  Bottom line, unless something is literally falling off or aesthetically grusome, men most often fall short of finishing a course of recommended treatment.  One way of improving fertility/sperm rates, would be to actually complete treatment protocols given by their healthcare provider.  I was looking looking through my past treatment schedules, and whether they are dragged in by their girlfriend or wife, or they actually decided on their own to 'check it out', most men stop treatment very early into the program protocol.  OK guys, its time to take more responsibility for your health, especially when it is affecting someone you love.
