The percentage of seminiferous tubules at each stage with greater than three total RSH in control and 0.33% HD treated testes. (A) Exposure to 0.33% HD for 11, 13, 15, and 18d. Treated testes first show a increase in the percentage of seminiferous tubules with greater than three RSH at stage X after 15d of exposure, which further increases to include stages IX-XI after 18d of exposure. Points significantly different from control are indicated with an “a”. (B) Exposure to 0.33% HD for 18d followed by a post-exposure recovery period of 1, 2, or 4 wk. After 1 and 2 wk of recovery, the percentage of seminiferous tubules with greater than three RSH is statistically identical to 18d of exposure (indicated with “a”). After 4 wk of recovery, the percentage of seminiferous tubules with greater than three RSH returns to the levels seen in control. See Supplemental Table 2 for SEM values at each point.
