Study Arms (4)
Control
NO INTERVENTIONGroup 1 will represent controls and will not receive prednisone in the 3-year post-op period.
Prednisone Monthly - Scheduled
EXPERIMENTALGroup 2 will receive 3, one-month courses of prednisone (20 mg daily x 1 week, 10 mg daily x 1 week, 5 mg x 2 weeks). These will be given at the beginning of months 0, 2, and 4 and will be self-administered.
Prednisone Monthly - As Needed
EXPERIMENTALGroup 3 will receive a maximum of 3, one-month courses of prednisone (20 mg daily x 1 week, 10 mg daily x 1 week, 5 mg x 2 weeks). These will be administered based on sequential semen analyses. If a semen analysis demonstrates a drop in concentration from a prior analysis or if it shows a 0 concentration, the course will be administered.
Prednisone Every Other Week
EXPERIMENTALGroup 4 will receive alternating 1 week dosages of prednisone (1 week on, 1 week off - 5 mg daily only) for a total of 24 weeks
Interventions
Treatment groups will be administered different dosages of Prednisone post vasectomy reversal.
