  1. T0, T2, T6, and T12 indicate the time-points (time zero, 2 months, 6 months, and 12 months, respectively) following intratesticular injection. Data are expressed as mean ± SD. After injection of calcium chloride, levels of testosterone in serum decreased: a = significant within group difference comparing T0 to T2-T12; b = significant between group difference comparing group A-D to control group E at T2-T12.
