Testis dimensions (mean ± SE) for hamsters undergoing regression in short days (SDs) in phase 1 or after pinealectomy in phase 2. Hamsters with intact pineal glands were maintained in 16L or 10L in phase 1 and then either pinx or sham-pinx at phase 2, week 0 (= phase 1, week 28). *Tukey test: all long-day (LD) versus all SD hamsters (p < 0.05). †Tukey test: LD-pinx different from LD-sham (p < 0.05). ‡Tukey test: LD-pinx different from all other groups (p < 0.05). The final mean ETV for the LD-pinx nonresponders (NR) is shown for comparison (gray shaded circle).
